Description

Electronic device wake-up method, electronic device, and computer-readable storage medium

Technical Field

The embodiments of the present application relate to the technical field of electronic devices, and in particular, to a method for waking up an electronic device, an electronic device, and a computer-readable storage medium.

Background technique

With the development of electronic devices, the buttons (such as power buttons, volume buttons, etc.) of many electronic devices (such as mobile phones, tablets, etc.) have evolved from physical buttons (physical buttons) to solid-state buttons. Among them, solid-state buttons are buttons without mechanical structures and elastic elements, and need to be implemented by using sensing technology. Therefore, compared with physical buttons, solid-state buttons need to implement additional analog signal acquisition functions. In this way, for electronic devices, the corresponding acquisition power consumption will be increased, which will increase the power consumption of electronic devices and reduce product life.

Summary of the invention

Embodiments of the present application provide a method for waking up an electronic device, an electronic device, and a computer-readable storage medium, which are used to solve the problem of increased power consumption and reduced product life of electronic devices with solid-state buttons.

To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

In a first aspect, a method for waking up an electronic device is provided, which is applied to an electronic device including a solid-state button. The solid-state button includes a microcontroller and a power button, and the power button includes a first sensor. The method includes: in a shipping mode, the microcontroller controls the first sensor to collect signals at a first frequency. Then, after detecting a first touch operation of the user on the power button, in response to the first touch operation, the first sensor collects a first touch signal corresponding to the first touch operation at a first frequency, and the microcontroller switches the working mode of the electronic device from the shipping mode to the running mode according to the first touch signal corresponding to the first touch operation. The first frequency is less than the second frequency corresponding to the shutdown mode.

In the first aspect, since the lower the acquisition frequency of the sensor of the solid-state button, the lower the acquisition power consumption required by the sensor of the solid-state button, the lower the power consumption required for the corresponding solid-state button to collect analog signals. Therefore, according to different low-power modes, different corresponding acquisition frequencies can be set for the sensor to reduce power consumption. Thus, when the electronic device is in the low-power mode of shipping mode, the sensor corresponding to the solid-state button can adaptively drop to the corresponding first frequency and collect signals at the first frequency, so that in the shipping mode, the power consumption required by the solid-state button is reduced, thereby reducing the power consumption of the electronic device in the shipping mode and improving the battery life of the product. At the same time, the first frequency in the shipping mode is less than the second frequency in the shutdown mode, which can further optimize the power consumption in the shipping mode and improve the battery life of the product in the shipping mode.

In another possible implementation of the first aspect, in the shipping mode, the microcontroller first controls the first sensor to collect signals at a third frequency that is less than the first frequency. After detecting the second touch operation of the user on the power button, first responding to the second touch operation, the first sensor collects a touch signal corresponding to the second touch operation at the third frequency, and the microcontroller controls the first sensor to collect signals at the first frequency according to the touch signal corresponding to the second touch operation. Then, if the user's first touch operation on the power button is detected, responding to the first touch operation, the first sensor collects a first touch signal corresponding to the first touch operation at the first frequency, and the microcontroller switches the working mode of the electronic device from the shipping mode to the running mode according to the first touch signal corresponding to the first touch operation.

In this implementation, the sensor acquisition frequency is first reduced to a third frequency lower than the first frequency in the shipping mode, which can further save the power consumption required by the solid-state buttons during the shipping wake-up waiting process, thereby further reducing the power consumption of the electronic device in the shipping mode and improving the product life in the shipping mode. At the same time, since the touch signal used to wake up the electronic device needs to ensure that it can be successfully collected at a certain acquisition frequency, after detecting the user's second touch operation on the power button, the microcontroller immediately increases the acquisition frequency from the third frequency to the first frequency to ensure that the first touch signal corresponding to the first touch operation can be successfully collected to realize the wake-up of the electronic device. That is, through this acquisition frequency conversion method, more power consumption can be saved while ensuring the wake-up response in the shipping mode, further improving the product life.

In another possible implementation of the first aspect, in shutdown mode, the microcontroller controls the first sensor to collect signals at a second frequency. Further, after detecting a third touch operation of the user on the power button, in response to the third touch operation, the first sensor collects a second touch signal corresponding to the third touch operation at a second frequency, and the microcontroller switches the working mode of the electronic device from the shipping mode to the running mode according to the second touch signal corresponding to the third touch operation. The second frequency is less than the collection frequency corresponding to the standby mode and the collection frequency corresponding to the running mode.

In this implementation, similar to the shipping mode, when the electronic device is in the low-power mode of shutdown mode, the sensor corresponding to the solid-state button can adaptively drop to the corresponding second frequency and collect signals at the second frequency, so that in shutdown mode, the power consumption required by the solid-state button is reduced, thereby reducing the power consumption of the electronic device in shutdown mode and improving product life.

In another possible implementation of the first aspect, in shutdown mode, the microcontroller first controls the first sensor to collect signals at a fourth frequency that is less than the second frequency. After detecting a fourth touch operation of the user on the power button, first responding to the fourth touch operation, the first sensor collects a touch signal corresponding to the fourth touch operation at a fourth frequency, and the microcontroller controls the first sensor to collect signals at a second frequency according to the touch signal corresponding to the fourth touch operation. Then, if a third touch operation of the user on the power button is detected, responding to the third touch operation, the first sensor collects a second touch signal corresponding to the third touch operation at a second frequency, and the microcontroller switches the working mode of the electronic device from the shipping mode to the running mode according to the second touch signal corresponding to the third touch operation.

In this implementation, the acquisition frequency of the sensor is first reduced to a fourth frequency lower than the second frequency in shutdown mode, which can further save the power consumption required by the solid-state buttons during the shutdown wake-up waiting process, thereby further reducing the power consumption of the electronic device in shutdown mode and improving the product life in shutdown mode. At the same time, since the touch signal used to wake up the electronic device needs to ensure that it can be successfully collected at a certain acquisition frequency, after detecting the user's fourth touch operation on the power button, the microcontroller immediately increases the acquisition frequency from the fourth frequency to the second frequency to ensure that the second touch signal corresponding to the third touch operation can be successfully collected to realize the wake-up of the electronic device. That is, through this acquisition frequency conversion method, more power consumption can be saved while ensuring the wake-up response in shutdown mode, further improving the product life.

In another possible implementation of the first aspect, the acquisition frequency of the standby mode is less than the acquisition frequency of the operating mode. By further distinguishing the acquisition frequencies of the operating mode and the standby mode, the power consumption required by the solid-state buttons in the standby mode can be reduced, the power consumption of the electronic device in the standby mode can be further reduced, and the battery life of the product in the standby mode can be improved.

In another possible implementation of the first aspect, after the working mode of the electronic device is switched from the shipping mode to the operating mode, the microcontroller adds a non-shipping mode flag to ensure the implementation of shipping mode identification. According to the non-shipping mode flag, the microcontroller can determine that the electronic device is not currently in the shipping mode.

In another possible implementation of the first aspect, the wake-up method of the electronic device further includes identifying the working mode of the electronic device, including identifying the shipping mode and the shutdown mode. Specifically, if the microcontroller determines that the electronic device is not in the running mode or the standby mode, and there is no non-shipping mark, the microcontroller can determine that the electronic device is in the shipping mode. If the microcontroller determines that the electronic device is not in the running mode or the standby mode, and there is a non-shipping mark, the microcontroller can determine that the electronic device is in the shutdown mode. The non-shipping mark includes a non-shipping mode flag or a shipping mode signal.

In another possible implementation of the first aspect, the solid-state button further includes a non-power button, and the non-power button includes a second sensor; the wake-up method of the electronic device may further include: in the shipping mode or the shutdown mode, the microcontroller controls the second sensor to power off. In this implementation, since the wake-up response is usually achieved by touching the power button, for the non-power button (such as the volume button), it is highly likely that no response is required in low-power modes such as the shipping mode and the shutdown mode, so the second sensor corresponding to the non-power button can be powered off to save the power consumption of the second sensor in the low-power mode, further reduce the power consumption of the electronic device, and improve the product life.

In another possible implementation of the first aspect, in order to prevent the user from waking up by mistake, the touch signal for waking up the electronic device from the shipping mode to the operating mode needs to meet a certain duration and/or preset requirements (for example, the pressure sensor needs to have a certain pressing force). Based on this, the microcontroller switches the operating mode of the electronic device from the shipping mode to the operating mode according to the first touch signal corresponding to the first touch operation, which may include: if the first touch signal includes n consecutive touch signal values that meet the first preset requirement, switching the operating mode of the electronic device from the shipping mode to the operating mode in response to the first touch signal; wherein n is the first touch duration required for the power button in the shipping mode.

In another possible implementation of the first aspect, similarly, in order to prevent the user from waking up by mistake, the touch signal of the electronic device waking up and switching from the shutdown mode to the operating mode also needs to meet a certain duration and/or preset requirements (for example, the pressure sensor needs to have a certain pressing force). Therefore, the microcontroller switches the working mode of the electronic device from the shutdown mode to the operating mode according to the second touch signal corresponding to the third touch operation, which may include: if the second touch signal includes m consecutive touch signal values that meet the second preset requirement, the working mode of the electronic device is switched from the shutdown mode to the operating mode in response to the second touch signal; wherein m is the second touch duration required for the power button in the shutdown mode.

Detailed ways

The technical scheme of the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Among them, in the description of the embodiment of the present application, the terms used in the following embodiments are only for the purpose of describing a specific embodiment, and are not intended to limit the present application. In addition, in order to facilitate the clear description of the technical scheme of the embodiment of the present application, in the embodiment of the present application, if the words "first", "second" and the like are used to distinguish the same items or similar items with basically the same functions and effects. It can be understood by those skilled in the art that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not limit necessarily different. And, in the description of the embodiment of the present application, unless otherwise specified, the meaning of "multiple" means two or more.

With the development of electronic devices, the buttons (such as power buttons, volume buttons, etc.) of many electronic devices (such as mobile phones, tablets, etc.) have evolved from physical buttons (physical buttons) to solid-state buttons (touch buttons). Among them, physical buttons are buttons with mechanical structures and elastic elements, which mainly realize the control of electronic devices through interruptions. For example, taking the power button as an example, the physical button can convert the electronic device from ship mode, shutdown mode, standby mode, etc. to operating mode through interruptions. However, solid-state buttons are buttons without mechanical structures and elastic elements, and need to be realized by using sensing technology. It can be simply understood that solid-state buttons are buttons that use sensors to realize corresponding functions.

Compared with physical buttons, solid-state buttons have better waterproof performance and simple appearance, and are the development trend of button form. However, since solid-state buttons need to cooperate with sensors to realize corresponding functions, compared with physical buttons, solid-state buttons require sensors to realize additional analog signal acquisition. In this way, for electronic devices, the corresponding acquisition power consumption will be increased, resulting in increased power consumption of electronic devices and reduced product life.

The problem of increased power consumption and reduced battery life of electronic devices is more obvious for those electronic devices that work in low-power modes such as shipping mode and shutdown mode. Because the working modes of electronic devices are shipping mode and shutdown mode, it generally indicates that the electronic devices currently need to save power. At this time, most functions of electronic devices will usually enter a dormant state, and the power management module will no longer supply power to the corresponding power-consuming components, thereby reducing the power consumption of electronic devices.

However, for solid-state buttons, in order to ensure that the solid-state buttons (such as the power button) can normally wake up the electronic device in low-power mode, so as to trigger the electronic device's working mode to switch from low-power mode to running mode. Therefore, even in low-power modes such as shipping mode and shutdown mode, the electronic device's analog signal acquisition function will continue to run, that is, in low-power mode, the solid-state buttons will continue to be powered. As a result, the power consumption required by the solid-state buttons in low-power mode will be very obvious, resulting in increased power consumption of the electronic device in low-power mode and reduced product life.

At the same time, the analog signal acquisition function on existing electronic devices is mainly realized by smart sensor hubs. However, the sensor hub is generally in a power-off state in low-power modes such as shipping mode and shutdown mode. Therefore, once the working mode of an electronic device is in a low-power mode such as shutdown mode or shipping mode, it is no longer possible to wake up the electronic device through the sensor hub and switch the working mode of the electronic device to the running mode. Therefore, most traditional solid-state buttons also need to add additional devices dedicated to waking up electronic devices in shipping mode and shutdown mode, which also increases product costs.

It should be noted that the above-mentioned shipping mode refers to a low-power mode that is set during transportation of electronic devices after they leave the factory. Its main purpose is to save power in electronic devices, thereby ensuring that the electronic devices can still have power for the user to turn on and use for the first time after being transported over long distances. The shipping mode is generally only used once, and the manufacturer sets the electronic device to shipping mode before leaving the factory. Subsequently, once the electronic device is awakened and switched from shipping mode to operating mode, the electronic device will no longer enter shipping mode. It is understandable that after the user purchases the device, the electronic device responds to the user's power-on operation to turn on the electronic device for the first time. This process can be regarded as the electronic device being awakened and switched from shipping mode to operating mode.

Based on this, an embodiment of the present application provides a method for waking up an electronic device, which is applied to an electronic device including a solid-state button. This method can reduce the power consumption of the solid-state button in low-power mode, thereby reducing the power consumption of the electronic device to improve the battery life of the product. In an embodiment of the present application, the solid-state button includes a microcontroller and a power button. The power button includes a first sensor for collecting a touch signal on the power button.

Specifically, the lower the acquisition frequency of the sensor of the solid-state button, the lower the acquisition power consumption required by the sensor of the solid-state button, and the correspondingly lower the power consumption required by the solid-state button for analog signal acquisition.

Therefore, the wake-up method of the electronic device provided in the embodiment of the present application is based on the power consumption requirements and characteristics of the electronic device in different types of low power consumption modes, and configures different acquisition frequencies for the sensor of the solid-state button for each different type of low power consumption mode. Among them, the low power consumption modes in the embodiment of the present application include shipping mode and shutdown mode.

Furthermore, as long as the electronic device enters the corresponding low-power mode, the microcontroller in the electronic device will adaptably reduce the acquisition frequency of the sensor of the solid-state button to the corresponding acquisition frequency. Subsequently, when the electronic device is in this low-power mode, if the user detects a touch operation on the solid-state button, the sensor can collect the corresponding touch signal (analog signal) in response to the touch operation and send it to the microcontroller, and the microcontroller will then switch the working mode of the electronic device from the low-power mode to the running mode according to the touch signal, so as to wake up the electronic device from the low-power mode.

For example, after the working mode of the electronic device is switched to the shipping mode, the acquisition frequency of the first sensor of the power button can be reduced to the first frequency corresponding to the shipping mode. If a user touch operation on the power button is detected in the shipping mode, the corresponding first sensor can respond to the touch operation and collect the corresponding touch signal (analog signal) at the reduced first frequency and send it to the microcontroller. Then, the microcontroller responds to the collected touch signal to switch the working mode of the electronic device from the shipping mode to the running mode, so as to wake up the electronic device from the shipping mode.

For another example, after the working mode of the electronic device is switched to the shutdown mode, the acquisition frequency of the first sensor of the power button can be reduced to the second frequency corresponding to the shutdown mode. If the user's touch operation on the power button is detected in the shutdown mode, the corresponding first sensor can respond to the touch operation and collect the corresponding touch signal (analog signal) at the reduced second frequency and send it to the microcontroller. Then, the microcontroller switches the working mode of the electronic device from the shutdown mode to the running mode in response to the collected touch signal, so as to wake up the electronic device from the shutdown mode.

In some embodiments, when the sensor of the solid-state button (such as the first sensor of the power button) is a pressure sensor, the touch signal collected by the sensor of the solid-state button (such as the first sensor of the power button) may be a continuous pressure signal.

Therefore, after the working mode of the electronic device is switched to the low power mode, the power consumption of the analog signal acquisition function is reduced due to the reduced adaptability of the acquisition frequency of the sensor of the solid-state button. Accordingly, the power consumption required by the solid-state button in the low power mode will be reduced, thereby reducing the power consumption of the electronic device in the low power mode and improving the product life.

In some embodiments, the purpose of an electronic device entering shipping mode is to ensure that the electronic device has enough power to ensure that the user can turn it on and use it for the first time, but the actual transportation route and transportation time of the electronic device are uncertain. Therefore, in order to ensure as much as possible that the electronic device still has power after a long-distance and long-term transportation. In the embodiment of the present application, the collection frequency corresponding to the shipping mode can be further less than the collection frequency corresponding to the shutdown mode. That is, the first frequency is less than the second frequency.

Therefore, by further distinguishing between shipping mode and shutdown mode, the power consumption in shipping mode can be further optimized, more power consumption can be saved in shipping mode, and the product transportation endurance can be improved. At the same time, the electronic device in shipping mode is not yet turned on and used, so the functional modules that need to consume power in shipping mode should be the least. In addition, electronic devices are usually packaged during transportation and are generally not touched and used by users. Therefore, even if the acquisition frequency of solid-state buttons in shipping mode is reduced to a minimum, it will not affect the use of electronic devices. Therefore, the effect of further improving the product transportation endurance can be achieved without affecting the use of electronic devices.

Fig. 1 shows a schematic block diagram of the structure of a solid-state key 10. The solid-state key 10 is described below in conjunction with Fig. 1 .

1 , the solid-state button 10 in the embodiment of the present application includes a power module, a microcontroller and a sensor module.

Among them, the sensor module includes a first sensor for a power button and a second sensor for a non-power button (such as a volume button). The power button can have different functions according to different working modes of the electronic device. For example, in low-power modes such as shipping mode and shutdown mode, the power button can be used to wake up the electronic device. For another example, in running mode and standby mode, the power button can be used to implement functions such as locking the screen and shutting down the electronic device. Non-power buttons, such as volume buttons, can be used to control the volume, such as increasing the volume of the electronic device and decreasing the volume of the electronic device.

The first sensor is a sensor for collecting touch signals corresponding to user touch operations on the power button, and the second sensor is a sensor for collecting touch signals corresponding to user touch operations on non-power buttons. The first sensor and the second sensor may include one or more sensors, or may include one or more groups of sensors, respectively.

For example, the first sensor may consist of one sensor alone, or may consist of multiple sensors together. For another example, the second sensor may consist of one sensor alone, or may consist of multiple sensors together. In some embodiments, the first sensor and the second sensor may be of the same type.

In some embodiments, when all buttons of the electronic device need to remain responsive, such as when the electronic device is in operating mode, the first sensor and the second sensor need to be powered on to remain responsive. In the case where some non-power buttons do not need to remain responsive, such as when the electronic device is in low-power modes such as shipping mode and shutdown mode, the microcontroller can control the second sensor corresponding to the non-power button to be powered off, thereby saving power consumption of the second sensor.

In addition, it can be understood that the solid-state button 10 can also include a touch panel. Correspondingly, the touch panel can include a touch panel corresponding to the power button, and can also include a touch panel for a non-power button. The touch panel can be set on the surface of the electronic device housing, and the touch panel is not shown in FIG. 1 of the embodiment of the present application. The user can implement the corresponding touch operation by touching the touch panel on the surface of the electronic device housing.

It should be noted that the battery, power management unit (PMU), power management IC (PMIC) and system on chip (SOC) in Figure 1 are all common configurations of electronic devices. Among them, the power management module PMU communicates with the power management chip PMIC through the system power management bus (SPMI).

The power module of the solid-state button 10 is powered directly from the battery and is independent of the power management module PMU in the electronic device. In other words, the power module of the solid-state button 10 is powered directly from the battery and supplies power to the sensor module and the microcontroller via the power module. Therefore, when the electronic device is in a low-power mode such as a shipping mode and a shutdown mode, the solid-state button 10 can also power the microcontroller and the sensor module of the solid-state button 10 through an independent power module, thereby ensuring that the solid-state button 10 can respond to the user's touch operation in the low-power mode to wake up the electronic device.

As shown in FIG1 , power source 0 refers to the battery directly supplying power to the power module, and power sources 2 and 3 respectively supply power to the sensor module and the microcontroller of the solid-state key 10 via the power module. It can be understood that the solid-state key 10 can be independently powered by the power module, so that the solid-state key 10 can also keep running in the low power consumption mode, which is a prerequisite for the electronic device to be awakened from the shipping mode and the shutdown mode.

At the same time, since different modules may require different power supply voltages, FIG1 uses power supply 0, power supply 2, and power supply 3 to distinguish the power supply of different modules in the solid-state key 10. Of course, the power supply voltages required by different modules in the solid-state key 10 may also be completely the same, for example, power supply 0 = power supply 2 = power supply 3. It can be understood that the specific setting of the power supply is determined according to the actual circuit design of the electronic device, and the embodiment of the present application does not impose any limitation on this.

In addition, power supply 1 in Fig. 1 is used to represent the power supply provided by the battery to the power management module PMU. In some embodiments, power supply 1 can be equal to power supply 0, power supply 2 and power supply 3, that is, power supply 0=power supply 1=power supply 2=power supply 3.

In some embodiments, the sensor module of the solid-state button 10 may include, in addition to the sensor (including the first sensor and the second sensor), a power supply selection circuit, a signal conditioning circuit and other circuits connected to the sensor.

The power supply selection circuit is used for power supply selection. The signal conditioning circuit is a circuit for conditioning the touch signal (analog signal) collected by the sensor (including the first sensor and the second sensor), so that the touch signal (analog signal) collected by the sensor can be suitable for subsequent circuit processing.

Specifically, the input of the power supply selection circuit can be connected to the power supply module, and the output of the power supply selection circuit can be connected to the first sensor and the second sensor respectively. The input of the signal conditioning circuit can be connected to the first sensor and the second sensor respectively, and the output of the signal conditioning circuit can be connected to the microcontroller.

In some embodiments, the sensor (including the first sensor and the second sensor) in the sensor module may be a pressure sensor. When the sensor is a pressure sensor, when the user touches and presses the solid-state button, the solid-state button can wake up the electronic device by collecting the user's pressure signal (analog signal).

For example, when a user touches and presses a power button (it may be a touch panel that touches and presses the power button), the first sensor corresponding to the power button collects the user's pressure signal and conditions the pressure signal (analog signal) through a signal conditioning circuit, and then transmits the conditioned pressure signal (analog signal) to a microcontroller. The microcontroller then decides whether to switch the working mode of the electronic device from a low power mode to a running mode based on the pressure signal (analog signal) to wake up the electronic device.

In addition, the pressure sensor can be a resistive pressure sensor or a capacitive pressure sensor, and can be set specifically according to actual needs. The embodiments of the present application do not impose any limitations on this.

It should be noted that the sensor of the solid-state button can be not only a pressure sensor, but also other types of sensors, such as a photoelectric sensor. It is understandable that the type of sensor depends on the product configuration of the actual electronic device. If the sensor of the solid-state button is a photoelectric sensor, then the sensor of the solid-state button can collect continuous light signals.

In some embodiments, the signal conditioning circuit may include a filter, an amplifier, etc., which may be configured according to actual needs, and the embodiments of the present application do not impose any limitation on this. For example, if a pressure sensor collects a pressure signal, the signal conditioning circuit filters, amplifies, and conditions the pressure signal. For another example, if a photoelectric sensor collects an optical signal, the signal conditioning circuit filters, amplifies, and conditions the optical signal.

The microcontroller of the solid-state button 10 can be a microcontroller unit (MCU), a single-chip microcomputer, a digital signal processor (DSP) and other types of chips. The microcontroller can be configured according to actual needs. The embodiment of the present application does not impose any limitation on the specific type of the microcontroller.

In the embodiment of the present application, the microcontroller of the solid-state button 10 is mainly responsible for the power supply control, working mode identification, working mode switching and other functions of the sensor module.

As shown in FIG1 , the microcontroller can send a control signal to the power management module PMU through a level control signal to control the switching of the working mode of the electronic device. For example, the microcontroller determines that the electronic device can be awakened from a low-power mode such as a shipping mode or a shutdown mode based on the touch signal collected by the sensor module, and when the working mode of the electronic device is switched to the running mode, the microcontroller can send a level control signal to the power management module PMU, so that the power management module PMU starts to supply power to the system-level chip SOC and other functional modules in the electronic device, and the electronic device enters the running mode.

In some embodiments, the system-on-chip (SOC) may enter a corresponding working state as the working mode of the electronic device changes. For example, the working state includes a running state corresponding to the running mode, a standby state corresponding to the standby mode, and the like.

Each working state of the system-level chip SOC can have specific functions and usage scenarios. By reasonably switching the working state of the system-level chip SOC, low power consumption of the system-level chip SOC can be achieved. The switching of various working states of the system-level chip SOC can be realized by the power management module PMU that powers it.

For example, in the running state, all functions of the electronic device are responsive and executable, so in order to enable the system-on-chip SOC to achieve a variety of different tasks and functions, the power management module PMU controls the system-on-chip SOC to enter the running state. In the running state, the power management module PMU maintains power supply to each functional module in the system-on-chip SOC, thereby ensuring that each functional module is in a responsive state.

For another example, when the electronic device is in standby mode, the power management module PMU controls the system-on-chip SOC to enter the corresponding standby state. The power management module PMU can only guarantee the power supply of some functional modules in some SOCs, for example, the power supply guarantee can quickly respond to the triggering of external events.

Therefore, in an embodiment of the present application, the microcontroller can also communicate with the system-on-chip SOC through a communication bus such as I2C/SPI to determine whether the electronic device is in an operating mode and a standby mode. That is, the microcontroller communicates with the system-on-chip SOC through a communication bus such as I2C/SPI to obtain the working state of the system-on-chip SOC. The working state of the electronic device is judged according to the working state of the system-on-chip SOC. For example, if the working state of the system-on-chip SOC is an operating state, then the microcontroller can determine that the electronic device is in an operating mode. If the working state of the system-on-chip SOC is a standby state, then the microcontroller can determine that the electronic device is in standby mode.

In addition, the microcontroller can also communicate directly with the system-on-chip SOC through communication buses such as I2C/SPI, thereby sending the data collected by the sensor and some behavior recognition results to the system-on-chip SOC, on this basis, more feature functions can be realized.

It can be seen that the solid-state button provided in the embodiment of the present application can continuously power the microcontroller through an independent power supply mode even in low power consumption mode, thereby realizing the wake-up of the electronic device in low power consumption mode without adding additional components, thereby reducing product costs.

The electronic device may be at least one of a mobile phone, a foldable electronic device, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) device, a virtual reality (VR) device, an artificial intelligence (AI) device, a wearable device, a vehicle-mounted device, a smart home device, or a smart city device, including the solid-state button 10 shown in FIG1 . The embodiment of the present application does not impose any special restrictions on the specific type of the electronic device.

FIG. 2 shows a schematic structural diagram of an electronic device 100 .

The electronic device 100 may include a processor 110 (such as a system-on-chip SOC in FIG. 1 ), an external memory interface 120, an internal memory 121, a universal serial bus (USB) connector 130, a charging management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, an earphone interface 170D, a sensor module 180, a solid-state button 190 (such as the solid-state button 10 in FIG. 1 ), a motor 191, an indicator 192, a camera module 193, a display screen 194, and a subscriber identification module (SIM) card interface 195, etc. The sensor module 180 may include a pressure sensor, a gyroscope sensor, an air pressure sensor, a magnetic sensor, an acceleration sensor, a distance sensor, a proximity light sensor, a fingerprint sensor, a temperature sensor, a touch sensor, an ambient light sensor, a bone conduction sensor, etc.

It is to be understood that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may include more or fewer components than shown in the figure, or combine some components, or split some components, or arrange the components differently. The components shown in the figure may be implemented in hardware, software, or a combination of software and hardware.

The solid-state button 190 (such as the solid-state button 10 of FIG. 1 ) may include a microcontroller, a power module, and a sensor (including a first sensor and a second sensor). The power module of the solid-state button 190 is connected to the battery 142 , and is directly powered by the battery 142 , and independently powers the microcontroller and the sensor of the solid-state button 190 .

The sensor (including the first sensor and the second sensor) of the solid-state button 190 is used to collect the touch signal generated by the user's touch operation on the solid-state button. In some embodiments, the sensor (including the first sensor and the second sensor) of the solid-state button 190 can be a pressure sensor. The pressure sensor is used to sense the pressure signal and can convert the pressure signal into an electrical signal. In some embodiments, there are many types of pressure sensors, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc. A capacitive pressure sensor can be a parallel plate including at least two conductive materials. When a force acts on the pressure sensor, the capacitance between the electrodes changes. The microcontroller determines the intensity of the pressure based on the change in capacitance. When a touch operation acts on the solid-state button 190, the microcontroller detects the pressing intensity of the touch operation based on the pressure sensor.

For example, if the first touch signal generated by the touch operation has a signal value of n consecutive pressing strengths greater than the first pressure threshold, the mode is switched from the shipping mode to the running mode. For another example, if the second touch signal generated by the touch operation has a signal value of m consecutive pressing strengths greater than the first pressure threshold, the mode is switched from the shutdown mode to the running mode.

The microcontroller of the solid-state button 190 is mainly responsible for the power supply control of the sensor, working mode identification, working mode switching and other functions. For example, in low power mode, the microcontroller of the solid-state button 190 can control the second sensor corresponding to the non-power button to power off to save power. For the first sensor corresponding to the power button, in low power mode, the microcontroller of the solid-state button 190 can control the first sensor to reduce the acquisition frequency accordingly, thereby controlling the first sensor to collect signals at the reduced acquisition frequency. That is, in shipping mode, the first sensor is controlled to collect signals at a first frequency, and in shutdown mode, the first sensor is controlled to collect signals at a second frequency. Alternatively, in operating mode, the first sensor corresponding to the power button and the second sensor corresponding to the non-power button both remain responsive. The power button can realize functions such as locking the screen and shutting down. Non-power buttons, such as volume buttons, can realize the function of increasing and decreasing the volume of electronic devices.

For another example, according to the touch signal collected by the first sensor corresponding to the power button, the microcontroller of the solid-state button 190 can control the working mode of the electronic device to switch from the low power mode to the running mode, thereby waking up the electronic device. The microcontroller of the solid-state button 190 can communicate with the processor 110 to determine the working mode of the electronic device according to the working state of the processor 110.

It is understandable that the microcontroller of the solid-state button 190 can generate an operation control signal according to the instruction operation code and the timing signal to complete the control of fetching and executing instructions. Specifically in the embodiment of the present application, the microcontroller of the solid-state button 190 can implement the wake-up method of the electronic device provided in the embodiment of the present application.

A memory may also be provided in the microcontroller of the solid-state button 190 for storing instructions and data. In some embodiments, the memory in the microcontroller may be a non-volatile memory. The non-volatile memory may store a non-shipping mode flag, thereby ensuring that the non-shipping mode flag is not easily lost.

The processor 110 may include one or more processing units, for example, the processor 110 may include an application processor (AP), a modem processor, a graphics processor (GPU), an image signal processor (ISP), a controller, a video codec, a digital signal processor (DSP), a baseband processor, and/or a neural-network processing unit (NPU), etc. Among them, different processing units may be independent devices or integrated into one or more processors. The processor may generate an operation control signal according to the instruction opcode and the timing signal to complete the control of fetching and executing instructions.

In some embodiments, the processor 110 may include one or more interfaces. The interface may include an inter-integrated circuit (I2C) interface, an inter-integrated circuit sound (I2S) interface, a pulse code modulation (PCM) interface, a universal asynchronous receiver/transmitter (UART) interface, a mobile industry processor interface (MIPI), a general-purpose input/output (GPIO) interface, a subscriber identity module (SIM) interface, and/or a universal serial bus (USB) interface, etc. The processor 110 may be connected to a touch sensor, an audio module, a wireless communication module, a display screen, a camera module, and the like through at least one of the above interfaces.

It is understandable that the interface connection relationship between the modules illustrated in the embodiment of the present application is only a schematic illustration and does not constitute a structural limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may also adopt different interface connection methods in the above embodiments, or a combination of multiple interface connection methods.

The external memory interface 120 can be used to connect an external memory card, such as a Micro SD card, to expand the storage capacity of the electronic device 100. The external memory card communicates with the processor 110 through the external memory interface 120 to implement a data storage function. For example, files such as music and videos are stored in the external memory card. Or files such as music and videos are transferred from the electronic device to the external memory card.

The internal memory 121 can be used to store computer executable program codes, which include instructions. The internal memory 121 may include a program storage area and a data storage area. Among them, the program storage area may store an operating system, an application required for at least one function (such as a sound playback function, an image playback function, etc.), etc. The data storage area may store data created during the use of the electronic device 100 (such as audio data, a phone book, etc.), etc. In addition, the internal memory 121 may include a high-speed random access memory, and may also include a non-volatile memory, such as at least one disk storage device, a flash memory device, a universal flash storage (UFS), etc. The processor 110 executes various functional methods or data processing of the electronic device 100 by running instructions stored in the internal memory 121, and/or instructions stored in a memory provided in the processor.

The USB connector 130 is an interface that complies with USB standard specifications and can be used to connect the electronic device 100 and peripheral devices. Specifically, it can be a Mini USB connector, a Micro USB connector, a USB Type C connector, etc.

The charging management module 140 is used to receive charging input from a charger. The charger may be a wireless charger or a wired charger. The power management module 141 (the power management module PMU shown in FIG. 1 ) is used to connect the battery 142 , the charging management module 140 and the processor 110 .

The wireless communication function of the electronic device 100 can be implemented through the antenna 1, the antenna 2, the mobile communication module 150, the wireless communication module 160, the modem processor and the baseband processor.

The electronic device 100 can realize the display function through a GPU, a display screen 194, and an application processor. The GPU is a microprocessor for image processing, which is connected to the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 110 may include one or more GPUs, which execute program instructions to generate or change display information. The display screen 194 is used to display images, videos, etc.

The electronic device 100 can realize the camera function through the camera module 193, ISP, video codec, GPU, display screen 194, application processor AP, neural network processor NPU, etc.

The electronic device 100 can implement audio functions such as music playing and recording through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the headphone jack 170D, and the application processor.

The motor 191 can generate a vibration prompt. The motor 191 can be used for incoming call vibration prompts, and can also be used for touch vibration feedback. The indicator 192 can be an indicator light, which can be used to indicate the charging status, power changes, messages, missed calls, notifications, etc. The SIM card interface 195 is used to connect a SIM card.

It should be noted that the wake-up methods of electronic devices in the following embodiments can all be implemented in the electronic device 100 having the above hardware structure.

In some embodiments, in order to reduce the power consumption required for the solid-state button (i.e., reduce the power consumption required for the analog signal acquisition function), the response speed of the solid-state button can be guaranteed. The embodiment of the present application corresponds to four different working modes of the electronic device, and the working modes of the solid-state button are also divided into four types. That is, the four working modes of the solid-state button are shipping mode, shutdown mode, standby mode and operation mode. In the embodiment of the present application, the difference between these four working modes is that the acquisition frequency of the sensor is different and the number of sensors that maintain power supply and signal acquisition is different.

Furthermore, according to the required response speed, actual working requirements, power saving requirements, and the fact that the shipping mode can be further distinguished from the shutdown mode as described above to save more power in the shipping mode, the acquisition frequencies corresponding to the four working modes are in an increasing state. That is, the acquisition frequency of the shipping mode is less than the acquisition frequency of the shutdown mode, the acquisition frequency of the shutdown mode is less than the acquisition frequency of the standby mode, and the acquisition frequency of the standby mode is less than the acquisition frequency of the running mode.

The acquisition frequency, number of sensors, average current, etc. corresponding to the four working modules of the solid-state button in the embodiment of the present application can be referred to as shown in the following Table 1.

Table 1

Among them, the acquisition sensors shown in Table 1 refer to the sensors in the solid-state buttons. When the electronic device is in different working modes, the number of acquisition sensors working in the solid-state buttons is different. The number of acquisition sensors is the number of sensors that are powered to maintain operation and signal acquisition in the corresponding mode. For example, in the operating mode, all functional modules of the electronic device are powered on and running, so all sensors of the solid-state buttons must be powered on and running. For example, the first sensor corresponding to the power button needs to be powered on and in the running state to respond to the user's touch operation at any time to realize functions such as lock screen and shutdown. The second sensor corresponding to the non-power button (such as the volume button) also needs to be powered on and in the running state to respond to the user's touch operation at any time to realize the corresponding button function (such as realizing the volume increase and decrease function of the electronic device). Therefore, as shown in Table 1, the number of acquisition sensors at this time is the maximum number. The specific value of the maximum number depends on the number of sensors actually included in the solid-state button in the electronic device, and the embodiment of the present application does not impose any limitation on this.

For another example, in shutdown mode and shipping mode, in order to reduce power consumption, most functional modules of the electronic device are in a power-off state, and only the functional modules required for awakening can be powered. Therefore, only one sensor of the solid-state button can be kept in an operating state, that is, the first sensor corresponding to the power button for awakening the electronic device is kept. At this time, only the first sensor remains powered, as shown in Table 1, and the number of acquisition sensors is 1.

It should be noted that the acquisition frequency, number of acquisition sensors, etc. in Table 1 are examples of the embodiments of the present application, which can be modified and configured according to actual needs, and Table 1 does not constitute any limitation thereto. For example, the number of acquisition sensors in shutdown mode can also be configured to 2. For another example, the acquisition frequency, number of sensors, average current, etc. corresponding to the four working modules of the solid-state button in the embodiment of the present application can also be referred to as shown in Table 2 below.

Table 2

It can be understood that it is only necessary that the configured parameters can ensure the response speed and ensure that the four working modes increase the acquisition frequency in a progressive manner according to the above description.

Specifically, the microcontroller of the solid-state button can determine the working mode to be switched by the solid-state button by judging the working mode of the electronic device, and then the microcontroller controls the acquisition frequency of the sensor of the solid-state button to reduce the acquisition frequency of the sensor of the solid-state button to reduce the acquisition power consumption required by the solid-state button, thereby reducing the power consumption of the electronic device and improving the battery life of the product.

For example, if the working mode of the electronic device is switched to the shipping mode, the working mode of the solid-state button is correspondingly switched to the shipping mode, so that the microcontroller controls the sensor's acquisition frequency to be reduced to the acquisition frequency corresponding to the shipping mode. For another example, if the working mode of the electronic device is switched to the shutdown mode, the working mode of the solid-state button is correspondingly switched to the shutdown mode, so that the microcontroller can control the sensor's acquisition frequency to be reduced to the acquisition frequency corresponding to the shutdown mode.

As shown in Fig. 3, a flow chart of switching the working mode of a solid-state key is shown. In the following, the process of switching the working mode of a solid-state key is described in conjunction with Fig. 3.

Referring to Figure 3, the microcontroller of the solid-state key first determines the working mode of the electronic device. Then, since the electronic device can only operate in one working mode at the same time, the microcontroller of the solid-state key can control the solid-state key to enter the corresponding working mode according to the determined working mode of the electronic device.

Specifically, if the microcontroller of the solid-state button determines that the working mode of the electronic device is in the running mode, the solid-state button enters the running mode accordingly. That is, the microcontroller of the solid-state button keeps powering all sensors and controls the sensors to set the acquisition frequency to the acquisition frequency (sixth frequency) corresponding to the running mode, such as 80-100 Hz (sixth frequency) in Table 1.

That is, in the operating mode, the microcontroller can control the sensor to collect signals at the sixth frequency. In some embodiments, in the operating mode, the microcontroller can control the first sensor corresponding to the power button to collect signals at the sixth frequency. At the same time, the microcontroller can control the second sensor corresponding to the non-power button to collect signals at the sixth frequency.

Similarly, if the microcontroller of the solid-state button determines that the working mode of the electronic device is in the standby mode, the solid-state button enters the standby mode accordingly. The microcontroller of the solid-state button keeps powering all sensors and controls the sensors to set the acquisition frequency to the acquisition frequency (fifth frequency) corresponding to the standby mode, such as 30 to 50 Hz (fifth frequency) in Table 1, and the solid-state button enters the standby mode.

That is, in standby mode, the microcontroller can control the sensor to collect signals at the fifth frequency. In some embodiments, in standby mode, the microcontroller can control the first sensor corresponding to the power button to collect signals at the fifth frequency. At the same time, the microcontroller can control the second sensor corresponding to the non-power button to collect signals at the fifth frequency.

If the microcontroller of the solid-state button determines that the working mode of the electronic device is in the shutdown mode, the solid-state button enters the shutdown mode accordingly. The microcontroller of the solid-state button controls the sensor to set the acquisition frequency to the acquisition frequency (second frequency) corresponding to the shutdown mode, such as 1 to 2 Hz (second frequency) in Table 1, and the solid-state button enters the shutdown mode.

That is, in shutdown mode, the microcontroller can control the sensor to collect signals at the second frequency. For example, in some embodiments, in shutdown mode, the microcontroller can control the first sensor corresponding to the power button to collect signals at the second frequency. At the same time, the microcontroller can control the second sensor corresponding to the non-power button to collect signals at the second frequency.

For another example, in some other embodiments, since only the power button may need to remain responsive in shutdown mode, in order to ensure the solid-state button response while further saving the power consumption of the solid-state button, the microcontroller of the solid-state button can also control the power supply of the sensor. Therefore, in shutdown mode, while the microcontroller controls the first sensor corresponding to the power button to collect signals at the second frequency, the microcontroller controls the second sensor corresponding to the non-power button to be powered off.

If the microcontroller of the solid-state button determines that the working mode of the electronic device is in the shipping mode, the solid-state button enters the shipping mode accordingly. The microcontroller of the solid-state button controls the sensor to set the acquisition frequency to the acquisition frequency (first frequency) corresponding to the shipping mode, such as 0.5-1 Hz (first frequency) in Table 1, and the solid-state button enters the shipping mode.

That is, in the shipping mode, the microcontroller can control the sensor to collect signals at a first frequency. For example, in some embodiments, in the shipping mode, the microcontroller can control the first sensor corresponding to the power button to collect signals at a second frequency. At the same time, the microcontroller can control the second sensor corresponding to the non-power button to collect signals at a second frequency. As shown in Table 1, in the shutdown mode, the number of collecting sensors is 1.

For another example, in some other embodiments, since the power button may only need to remain responsive in the shipping mode, in order to ensure the solid-state button response while further saving the power consumption of the solid-state button in the shipping mode, the microcontroller of the solid-state button can also control the power supply of the sensor. Therefore, in the shipping mode, the microcontroller controls the first sensor corresponding to the power button to collect signals at the first frequency, while the microcontroller controls the second sensor corresponding to the non-power button to be powered off. As shown in Table 1, in the shipping mode, the number of collecting sensors is 1.

In order to ensure the response speed of the solid-state key while reducing the power consumption of the solid-state key in different working modes as much as possible, the relationship between the acquisition frequencies corresponding to each working mode is: sixth frequency>fifth frequency>second frequency>first frequency.

That is to say, as shown in FIG3 , in the shipping mode and the shutdown mode, the microcontroller of the solid-state button can also control the first sensor corresponding to the power button to keep powered, and control the second sensor corresponding to the non-power button to power off (i.e. stop powering), thereby saving the power consumption of the second sensor corresponding to the non-power button, further reducing the power consumption of the electronic device, and improving the battery life of the product.

As shown in Fig. 4, a flow chart of identifying the working mode of an electronic device is shown. In the following, the identification process of the working mode of an electronic device is described in conjunction with Fig. 4.

Referring to Figure 4, first, the microcontroller of the solid-state button can interact with the SOC through a communication bus such as I2C/SPI at a certain period to determine whether the electronic device is in standby mode or running mode. As mentioned above, since the working state of the SOC is controlled by the power management module PMU, the working mode of the electronic device is switched. Therefore, the microcontroller communicates with the SOC through a communication bus such as I2C/SPI at a certain period to obtain the working state of the SOC. Furthermore, the microcontroller determines the working mode of the electronic device according to the working state of the SOC.

If the microcontroller of the solid-state button determines that the electronic device is in standby mode or running mode through interaction with the SOC, the microcontroller of the solid-state button can determine that the current working mode of the electronic device is running mode or standby mode. Then, the solid-state button can switch into standby mode or running mode. That is, all sensors are powered on, and the microcontroller controls the sensor to set the acquisition frequency to the corresponding fifth frequency or sixth frequency, so that the sensor collects signals at the fifth frequency or sixth frequency in standby mode or running mode.

If the microcontroller determines that the electronic device is not in the standby mode or the operating mode by interacting with the SOC, the microcontroller further determines whether the current working mode of the electronic device is the off mode or the shipping mode. Specifically, the microcontroller can determine whether the current working mode of the electronic device is the off mode or the shipping mode by determining whether there is an off ship mode flag bit in the electronic device.

If the microcontroller determines that there is an off ship mode flag in the electronic device, indicating that the off ship mode flag is in a set state, then it is determined that the electronic device is in shutdown mode. In this way, the solid-state button can be switched into shutdown mode. In shutdown mode, the solid-state button only needs to ensure that the first sensor corresponding to the power button remains powered, and at the same time, the acquisition frequency of the first sensor is reduced to the second frequency.

If the microcontroller determines that there is no off ship mode flag in the electronic device, indicating that the off ship mode flag is in an unset state, then it is determined that the electronic device is in off ship mode. In this way, the solid-state button can be switched into the off ship mode. In the off ship mode, the solid-state button also only ensures that the first sensor corresponding to the power button remains powered, but the acquisition frequency of the first sensor needs to be reduced to the first frequency. In some embodiments, the first frequency is less than the second frequency.

In summary, the off ship mode flag can be understood as an indicator for determining whether the electronic device is in shipping mode. Before the electronic device is powered on for the first time, that is, before the electronic device is switched from shipping mode to operating mode, the off ship mode flag does not exist in the electronic device, that is, the off ship mode flag is not set at this time. At this stage, the microcontroller can determine whether the electronic device is in shipping mode.

When the electronic device is in the shipping mode, in response to the user's touch operation (such as the first touch operation) on the power button to realize the first power-on, the microcontroller or the system-on-chip SOC (i.e., the processor 110) can set the off-ship mode flag. In the embodiment of the present application, the setting can be understood as adding the off-ship mode flag in the electronic device. As a result, the off-ship mode flag is stored in the electronic device, and the microcontroller can determine whether the electronic device is in the off-ship mode. Among them, the off-ship mode includes the running mode, the standby mode and the shutdown mode, and the specific microcontroller can further determine.

Therefore, when the electronic device is not in standby mode or operating mode, if the off-ship mode flag is present, it indicates that the electronic device is in shutdown mode. When the electronic device is not in standby mode or operating mode, if the off-ship mode flag is absent, it indicates that the electronic device is in shipping mode.

It can be simply understood that as long as the off ship mode flag exists in an electronic device, it indicates that the electronic device is not in shipping mode.

In some embodiments, in order to facilitate the microcontroller to simply and quickly determine whether the off ship mode flag is set, the off ship mode flag in the embodiment of the present application can be written into the microcontroller.

Meanwhile, in other embodiments, since the shipping mode is only once, once the off ship mode flag is added (set), its stability must be ensured and it is not easily lost. Therefore, the off ship mode flag can be written into the non-volatile memory of the microcontroller. In some embodiments, the microcontroller or the system-on-chip SOC (i.e., the processor 110) can write the off ship mode flag into the non-volatile memory of the microcontroller to indicate that the electronic device is not in the shipping mode.

For example, in the shipping mode, if the microcontroller of the solid-state button detects a user's touch operation (such as the first touch operation) on the power button and has awakened the electronic device in response to the touch operation (such as the first touch operation) and switched the working mode of the electronic device from the shipping mode to the running mode, then the microcontroller can add an off-ship mode flag bit accordingly to indicate that the electronic device is no longer in the shipping mode.

That is, after the microcontroller switches the working mode of the electronic device from the shipping mode to the running mode according to the first touch signal (the touch signal collected in response to the user's first touch operation on the power button in the shipping mode), the microcontroller adds the off ship mode flag.

In some embodiments, the microcontroller of the solid state key may write this off ship mode flag into the non-volatile memory of the microcontroller.

For another example, in another case, when the microcontroller of the solid-state button determines that the working mode of the electronic device needs to be switched from the shipping mode to the running mode in response to the user's touch operation, it will synchronously send a level control signal to the power management module PMU of the electronic device to instruct the power management module PMU to control the electronic device to switch from the shipping mode to the running mode. Therefore, the system-on-chip SOC of the electronic device will also be awakened by the power management module PMU, so that the working state of the SOC is switched to the running state. Therefore, after the system-on-chip SOC wakes up and enters the running state, the SOC can also write this off-ship mode flag in the non-volatile storage of the microcontroller.

As shown in Fig. 5, a setting process of the SOC setting the off ship mode flag is shown. In the following, the process of the SOC setting the off ship mode flag is described in conjunction with Fig. 5.

Referring to FIG5 , after the electronic device switches from the shipping mode to the running mode, that is, after the working state of the SOC switches from the shipping state to the running state, the SOC can first read whether the off ship mode flag is stored in the non-volatile memory of the microcontroller through a communication bus such as I2C/SPI.

If the SOC reads and determines that there is an off ship mode flag in the non-volatile memory of the microcontroller, then it indicates that the off ship mode flag is currently set, that is, the off ship mode flag has been added, and the process ends.

If the SOC determines through reading that there is no off ship mode flag in the non-volatile memory of the microcontroller, then the off ship mode flag is not set, that is, the off ship mode flag has not been added. Therefore, the SOC can write this off ship mode flag to the non-volatile memory of the microcontroller through a communication bus such as I2C/SPI.

In some embodiments, the shipping mode can be determined by a level signal in addition to being determined by an off ship mode flag. In an embodiment of the present application, one input/output signal (IO signal) can be selected from the power management module PMU as the shipping mode signal of the electronic device and connected to the microcontroller of the solid-state button. The power management module PMU uses this IO signal to transmit information to the microcontroller of the solid-state button whether the electronic device is in shipping mode. Hereinafter, this embodiment of the present application refers to this IO signal as a shipping mode signal.

Exemplarily, a high level signal may be used to represent a non-shipping mode, and a low level signal may be used to represent a shipping mode. In some embodiments, in a digital circuit, a high level signal may be represented by 1, and a low level signal may be represented by 0.

For example, before the electronic device starts to be transported, the manufacturer's personnel send control instructions to the electronic device by controlling the upper computer connected to the electronic device to control the electronic device to enter the shipping mode. When the electronic device enters the shipping mode, the power management module PMU controls most of the functional modules of the electronic device to power off. At the same time, the power management module PMU sets the IO signal (shipping mode signal) connected to the microcontroller of the solid-state button to a low-level signal. Therefore, because the connected IO signal (shipping mode signal) is a low-level signal (such as the signal is 0), the power management module PMU can transmit the information that the electronic device is currently in shipping mode to the microcontroller of the solid-state button through this IO signal (shipping mode signal) connected. Furthermore, when the microcontroller enters the electronic device working mode identification process, it can be determined whether the electronic device is in shipping mode through this IO signal connected to the power management module PMU.

If this IO signal (shipping mode signal) is a low level signal (such as the signal is 0), the microcontroller determines that the current working mode of the electronic device is the shipping mode. If this IO signal (shipping mode signal) is a high level signal (such as the signal is 1), the microcontroller determines that the current working mode of the electronic device is the non-shipping mode. Similarly, the non-shipping mode in the embodiment of the present application includes the operating mode, the standby mode and the shutdown mode. The microcontroller can further determine which non-shipping mode the electronic device is in.

As shown in FIG6 , a setting process of a shipping mode signal is shown. That is, after the power management module PMU receives the control instruction issued by the host computer for controlling the electronic device to enter the shipping mode, the power management module PMU first determines whether the 1-way shipping mode signal (IO signal) is a low-level signal. If the 1-way shipping mode signal (IO signal) is a low-level signal (such as the signal is 0), the power management module PMU does not control the 1-way shipping mode signal (IO signal) to change, so that the 1-way shipping mode signal (IO signal) continues to maintain a low-level signal (such as the signal is 0).

If the shipping mode signal (IO signal) is a high level signal, the power management module PMU sets the shipping mode signal (IO signal) from a high level signal to a low level signal to indicate to the microcontroller of the solid-state button that the current working mode of the electronic device is the shipping mode. In this way, the microcontroller of the solid-state button can determine that the electronic device is currently in the shipping mode through the connected shipping mode signal (IO signal).

In other embodiments, when the microcontroller of the solid-state key determines that the working mode of the electronic device is switched from the shipping mode to the running mode according to the touch signal corresponding to the user's touch operation (the first touch signal corresponding to the first touch operation), the microcontroller sends a level control signal as shown in FIG1 to the power management module PMU to control the electronic device to switch into the running mode, that is, to control the power management module PMU to restore power to each functional module of the electronic device. At this time, the power management module PMU can change the 1-way shipping mode signal (IO signal) from the set low level signal to a high level signal to indicate that the electronic device is in non-shipping mode at this time.

As shown in FIG. 7 , a process of determining the working mode of an electronic device based on a shipping mode signal (I0 signal) is shown.

Referring to FIG7 , if the I0 signal (shipping mode signal) is a high-level signal, the microcontroller of the solid-state button can determine that the electronic device is in a non-shipping mode, so that the microcontroller of the solid-state button can determine that the solid-state button needs to be switched into a non-shipping mode. Further, for the judgment of the non-shipping mode, the microcontroller can also determine whether the electronic device is currently in a standby mode or an operating mode by communicating with the SOC. If it is determined through communication with the SOC that the electronic device is in standby mode or operating mode, it is determined that the electronic device is in standby mode or operating mode at this time, and the microcontroller can determine that the solid-state button is switched into standby mode or operating mode. If it is determined through communication with the SOC that the electronic device is not in standby mode or operating mode, it is determined that the electronic device is in shutdown mode at this time, and the solid-state button is switched into shutdown mode.

On the contrary, if the I0 signal (shipping mode signal) is a low level signal, the microcontroller of the solid-state button can determine that the electronic device is in the shipping mode. Similarly, when the electronic device is determined to be not in the standby mode or the running mode by communicating with the SOC, it can be determined that the electronic device is in the shipping mode at this time, and then it can be determined that the solid-state button is switched into the shipping mode.

In general, the electronic device in the embodiment of the present application can determine whether the electronic device is in the shipping mode according to the off-shipping mark, wherein the off-shipping mark includes the off-shipping mode flag or the shipping mode signal (I0 signal of the power management module PMU).

Fig. 8 shows a schematic flow chart of a method for waking up an electronic device, including steps S801-S805. The method for waking up an electronic device provided in an embodiment of the present application is described below in conjunction with Fig. 8.

S801, a microcontroller of a solid-state button determines whether the working mode of the electronic device is a shipping mode or a shutdown mode.

If the electronic device is not in the running mode or the standby mode, and there is no non-shipping mark, it is determined that the electronic device is in the shipping mode, and S802 is executed. If the electronic device is not in the running mode or the standby mode, and there is a non-shipping mark, it is determined that the electronic device is in the shutdown mode, and S804 is executed. The shipping mark includes a non-shipping mode flag bit and a shipping mode signal.

S802, the microcontroller of the solid-state button controls the first sensor to collect signals at a first frequency.

That is, in the shipping mode, the microcontroller controls the first sensor to reduce the acquisition frequency to the first frequency, so that the first sensor acquires the touch signal at the first frequency in the shipping mode.

The first sensor is a sensor corresponding to a power button (power on button). In the embodiment of the present application, the first frequency is less than the second frequency corresponding to the shutdown mode.

In some embodiments, the solid-state button also includes a non-power button (such as a volume button), and the non-power button includes a second sensor corresponding to the acquisition of a user touch signal. Generally, the non-power button of the electronic device does not need to be used and does not need to remain responsive in a low-power mode. Therefore, when the electronic device is in a shipping mode, the microcontroller of the solid-state button can control the second sensor to power off, thereby saving the power consumption of the non-power button in the shipping mode and improving the product's shipping life.

S803, in response to a first touch operation of the user on the power button, the microcontroller of the solid-state button switches the working mode of the electronic device from the shipping mode to the running mode according to a first touch signal corresponding to the first touch operation; wherein the first touch signal corresponding to the first touch operation is collected by the first sensor at a first frequency.

Specifically, in the shipping mode, if it is detected that the user presses the power button to perform a touch operation, the first sensor corresponding to the power button collects the touch signal corresponding to the press touch operation at the reduced first frequency. In the embodiment of the present application, the press touch operation of the power button by the user in the shipping mode is called the first touch operation, and the collected touch signal corresponding to the first touch operation is called the first touch signal.

Then, the microcontroller of the solid-state button determines whether the current pressing touch is a valid wake-up behavior based on the first touch signal collected by the first sensor. If it is a valid wake-up behavior, the microcontroller needs to respond to the first touch signal to wake up the electronic device and switch the working mode of the electronic device from the shipping mode to the running mode. If it is not a valid wake-up behavior, for example, it may be a false touch by the user, the microcontroller does not need to respond to the first touch signal to wake up the electronic device, and the working mode of the electronic device continues to be maintained in the shipping mode. In some embodiments, the microcontroller can send a control signal to the power management module PMU through a level control signal as shown in Figure 1 to control the electronic device to switch from the shipping mode to the running mode.

S804, the microcontroller of the solid-state button controls the first sensor to collect signals at a second frequency.

That is, in the shutdown mode, the microcontroller controls the first sensor to reduce the acquisition frequency to the second frequency, so that the first sensor acquires the touch signal at the second frequency in the shutdown mode.

The second frequency is the corresponding acquisition frequency in the shutdown mode, and the second frequency is greater than the first frequency in the shipping mode. In some embodiments, when the electronic device is in the shutdown mode, the non-power button also does not need to remain responsive, so the microcontroller of the solid-state button can also control the second sensor to power off, thereby saving power consumption of the non-power button in the shutdown mode, so as to improve the shutdown battery life of the product.

S805, in response to the user's third touch operation on the power button, the microcontroller of the solid-state button switches the working mode of the electronic device from the shutdown mode to the running mode according to the second touch signal corresponding to the third touch operation; wherein the second touch signal corresponding to the third touch operation is collected by the first sensor at the second frequency.

Similarly, in shutdown mode, if it is detected that the user presses the power button to perform a touch operation, the first sensor corresponding to the power button collects the touch signal corresponding to the press touch operation at the reduced second frequency. In the embodiment of the present application, the press touch operation of the power button by the user in shutdown mode is called the third touch operation, and the collected touch signal corresponding to the third touch operation is called the second touch signal.

Then, the microcontroller of the solid-state button determines whether the current pressing touch is a valid wake-up behavior based on the second touch signal collected by the first sensor. If it is a valid wake-up behavior, it is necessary to respond to the second touch signal to wake up the electronic device and switch the working mode of the electronic device from shutdown mode to running mode. If it is not a valid wake-up behavior, for example, it may be a false touch by the user, there is no need to respond to the second touch signal to wake up the electronic device, and the working mode of the electronic device continues to be maintained in shutdown mode. Similarly, in some embodiments, the microcontroller can send a control signal to the power management module PMU through a level control signal as shown in Figure 1 to control the electronic device to switch from shutdown mode to running mode.

In some embodiments, in order to reduce power consumption while ensuring that the power button can respond to the user's wake-up operation, the first frequency and the second frequency can be configured as the minimum frequency required for the first sensor to collect touch signals.

For example, the first frequency in the shipping mode can be set to 1 Hz, and the second frequency in the shutdown mode can be set to 2 Hz. It can be understood that the minimum frequency can be determined based on experience or by performing actual acquisition tests on the first sensor, and the present application embodiment does not impose any limitation on this.

It can be seen that in the embodiments of the present application, when the electronic device enters a low power consumption mode such as a shipping mode and a shutdown mode, the power button generally needs to remain responsive to wake up the electronic device. Therefore, in these low power consumption modes, the microcontroller of the solid-state button adaptively controls the first sensor of the power button to reduce the acquisition frequency, thereby reducing the power consumption required for analog signal acquisition, thereby reducing the power consumption of the electronic device in the low power consumption mode to improve the battery life of the product.

At the same time, the embodiment of the present application configures the corresponding first frequency and second frequency for the shipping mode and the shutdown mode respectively, and the first frequency is less than the second frequency. Thus, more power consumption can be further saved in the shipping mode, and the product transportation endurance can be improved.

Fig. 9 shows a schematic flow chart of another method for waking up an electronic device, including steps S901 to S907. In the following, another method for waking up an electronic device provided in an embodiment of the present application is described in conjunction with Fig. 9.

S901, a microcontroller of a solid-state button determines whether the working mode of the electronic device is a shipping mode or a shutdown mode.

The principle is the same as S901. If the electronic device is not in the running mode or the standby mode, and there is no non-shipping mark, it is determined that the electronic device is in the shipping mode. In the shipping mode, the embodiment of the present application then executes S902. If the electronic device is not in the running mode or the standby mode, and there is a non-shipping mark, it is determined that the electronic device is in the shutdown mode. In the shutdown mode, the embodiment of the present application then executes S905. Among them, the shipping mark includes a non-shipping mode flag and a shipping mode signal.

S902, the microcontroller of the solid-state button controls the first sensor to collect signals at a third frequency; wherein the third frequency is lower than the first frequency.

S903, in response to the user's second touch operation on the power button, the microcontroller of the solid-state button controls the first sensor to collect signals at the first frequency, wherein the touch signal corresponding to the second touch operation is collected by the first sensor at the third frequency.

S904, in response to a first touch operation of the user on the power button, the microcontroller of the solid-state button switches the working mode of the electronic device from the shipping mode to the running mode according to a first touch signal corresponding to the first touch operation, wherein the first touch signal corresponding to the first touch operation is collected by the first sensor at a first frequency.

The second touch operation is a touch operation in the shipping mode for instructing the microcontroller to increase the sensor acquisition frequency. The first touch operation is a touch operation instructing the microcontroller to switch the working mode of the electronic device from the shipping mode to the running mode.

In the embodiment of the present application, the second touch operation is a touch operation before the first touch operation. That is, the touch signal corresponding to the second touch operation is a touch signal before the first touch signal corresponding to the first touch operation.

In some embodiments, the touch signal corresponding to the second touch operation may be a single touch signal, and the first touch signal corresponding to the first touch operation may be a touch signal continuously including multiple touch signals. In other embodiments, the second touch operation and the first touch operation may be continuous touch operations, and the touch signal corresponding to the second touch operation and the first touch signal may be continuous touch signals.

Exemplarily, the first touch operation and the second touch operation are described below using a first time point, a second time point, and a third time point as examples, wherein the second time point is after the first time point, and the third time point is after the second time point.

If a user's touch operation is detected at the first time point, the touch operation is regarded as the second touch operation. In response to the touch signal corresponding to the second touch operation, the microcontroller increases the acquisition frequency of the first sensor from the third frequency to the first frequency at the second time point. Thereafter, if the user's touch operation is still detected at the second time point, the touch operation between the second time point and the third time point is continued to be acquired, and the touch operation is regarded as the first touch operation.

Specifically, in the embodiment of the present application, if the microcontroller of the solid-state button determines that the electronic device is in the shipping mode, the microcontroller of the solid-state button first reduces the acquisition frequency of the first sensor to a third frequency that is smaller than the first frequency. That is, in the shipping mode, the microcontroller of the solid-state button first controls the first sensor to collect signals at the third frequency. The third frequency is smaller than the first frequency. It can be understood that in the embodiment of the present application, the second sensor of the non-power button can also be controlled to be powered off to save the power consumption of the non-power button in the low-power mode, reduce the power consumption of the electronic device, and improve the battery life of the product.

Then, after detecting the second touch operation of the user on the power button, in response to the second touch operation, the touch signal corresponding to the second touch operation is collected at the third frequency. In response to the touch signal corresponding to the second touch operation, the microcontroller increases the collection frequency of the first sensor from the third frequency to the first frequency, so that the first sensor collects the first touch signal corresponding to the first touch operation at the first frequency. That is, in response to the second touch operation of the user on the power button, the microcontroller of the solid-state button controls the first sensor to collect signals at the first frequency. Among them, the touch signal corresponding to the second touch operation is collected by the first sensor at the third frequency. Afterwards, in response to the first touch operation of the user on the power button, the first sensor collects the first touch signal corresponding to the first touch operation at the first frequency and sends it to the microcontroller. Finally, the microcontroller of the solid-state button switches the working mode of the electronic device from the shipping mode to the running mode according to the first touch signal corresponding to the first touch operation.

In the embodiment of the present application, after the acquisition frequency of the first sensor is reduced to a third frequency which is lower than the first frequency, because the first frequency is already the lowest frequency that can ensure the wake-up response in the shipping mode, the first sensor may not be able to successfully complete the acquisition of the first touch signal if it is always maintained at the third frequency.

Therefore, in this case, if it is detected that the user presses and touches the power button, the microcontroller of the solid-state button first increases the acquisition frequency of the first sensor from the third frequency to the first frequency to ensure that the first sensor can successfully complete the acquisition of the first touch signal at the first frequency.

Then, the microcontroller of the solid-state button determines whether the current pressing touch (i.e., the first touch operation) is a valid wake-up behavior based on the first touch signal collected by the first sensor at the first frequency. If it is a valid wake-up behavior, it is necessary to respond to the first touch signal to wake up the electronic device and switch the working mode of the electronic device from the shipping mode to the running mode. If it is not a valid wake-up behavior, for example, it may be a false touch by the user, it is not necessary to respond to the first touch signal to wake up the electronic device, and the working mode of the electronic device continues to be maintained in the shipping mode.

In some embodiments, after the microcontroller increases the acquisition frequency of the first sensor from the third frequency to the first frequency, if the user's first touch operation is not detected, the acquisition frequency of the first sensor can be reduced from the first frequency to the third frequency. When waiting for the next second touch operation to arrive, the acquisition frequency of the first sensor is increased from the third frequency to the first frequency again. For example, if the microcontroller increases the acquisition frequency of the first sensor from the third frequency to the first frequency at the second time point and does not detect the user's first touch operation, the acquisition frequency of the first sensor can be reduced from the first frequency to the third frequency at the second time point. In this way, it is possible to avoid the user's accidental touch and increase the acquisition frequency.

S905, the microcontroller of the solid-state button controls the first sensor to collect signals at a fourth frequency; wherein the fourth frequency is lower than the second frequency.

S906, in response to the user's fourth touch operation on the power button, the microcontroller of the solid-state button controls the first sensor to collect signals at the second frequency, wherein the touch signal corresponding to the fourth touch operation is collected by the first sensor at the fourth frequency.

S907, in response to the user's third touch operation on the power button, the microcontroller of the solid-state button switches the working mode of the electronic device from the shutdown mode to the running mode according to the second touch signal corresponding to the third touch operation. The second touch signal corresponding to the third touch operation is collected by the first sensor at the second frequency.

The fourth touch operation has the same function as the second touch operation, and is a touch operation for instructing the microcontroller to increase the sensor acquisition frequency in shutdown mode. The third touch operation has the same function as the first touch operation, and is a touch operation for instructing the microcontroller to switch the working mode of the electronic device from shutdown mode to running mode.

Similarly, in the embodiment of the present application, the fourth touch operation is a touch operation before the third touch operation. In other words, the touch signal corresponding to the fourth touch operation is a touch signal before the second touch signal corresponding to the third touch operation.

In some embodiments, the touch signal corresponding to the fourth touch operation may be a single touch signal, and the second touch signal corresponding to the third touch operation may be a touch signal continuously including multiple touch signals. In other embodiments, the fourth touch operation and the third touch operation may be continuous touch operations, and the touch signal corresponding to the fourth touch operation and the second touch signal may be continuous touch signals.

Specifically, in an embodiment of the present application, if the microcontroller of the solid-state button determines that the electronic device is in shutdown mode, the microcontroller of the solid-state button first reduces the acquisition frequency of the first sensor to a fourth frequency that is smaller than the second frequency. That is, in shutdown mode, the microcontroller of the solid-state button first controls the first sensor to collect signals at the fourth frequency. The fourth frequency is less than the second frequency. It can be understood that in an embodiment of the present application, the second sensor of the non-power button can also be controlled to be powered off to save the power consumption of the non-power button in low-power mode, reduce the power consumption of the electronic device, and improve the battery life of the product.

Afterwards, when the user's fourth touch operation on the power button is detected, in response to the fourth touch operation, the touch signal corresponding to the fourth touch operation is acquired at the fourth frequency. In response to the touch signal corresponding to the fourth touch operation, the microcontroller increases the acquisition frequency of the first sensor from the fourth frequency to the second frequency, so that the first sensor acquires the second touch signal corresponding to the third touch operation at the second frequency. That is, in response to the user's fourth touch operation on the power button, the microcontroller of the solid-state button controls the first sensor to acquire the signal at the fourth frequency. Among them, the touch signal corresponding to the fourth touch operation is acquired by the first sensor at the fourth frequency. Afterwards, in response to the user's third touch operation on the power button, in response to the user's third touch operation on the power button, the first sensor acquires the second touch signal corresponding to the third touch operation at the second frequency and sends it to the microcontroller. Finally, the microcontroller of the solid-state button switches the working mode of the electronic device from the shutdown mode to the running mode according to the second touch signal corresponding to the third touch operation.

Also, because the second frequency is the lowest frequency that can ensure the wake-up response in shutdown mode, in order to ensure that the first sensor can successfully complete the acquisition of the second touch signal in shutdown mode. If it is detected that the user presses the power button, the microcontroller of the solid-state button first increases the acquisition frequency of the first sensor from the fourth frequency to the second frequency, so as to ensure that the first sensor can successfully complete the acquisition of the second touch signal at the second frequency.

Finally, the microcontroller of the solid-state button determines whether the current pressing touch (i.e., the third touch operation) is a valid wake-up behavior based on the second touch signal collected by the first sensor at the second frequency. If it is a valid wake-up behavior, it is necessary to respond to the second touch signal to wake up the electronic device and switch the working mode of the electronic device from the shutdown mode to the running mode. If it is not a valid wake-up behavior, for example, it may be a false touch by the user, there is no need to respond to the second touch signal to wake up the electronic device, and the working mode of the electronic device continues to be maintained in the shutdown mode.

In summary, in the embodiment of the present application, the acquisition frequency of the first sensor is first reduced to a third frequency lower than the first frequency in the shipping mode. At the same time, the acquisition frequency of the first sensor is also first reduced to a fourth frequency lower than the second frequency in the shutdown mode. Afterwards, in response to the user's first wake-up operation (such as the second touch operation and the fourth touch operation), the acquisition frequency is immediately increased to the first frequency or the second frequency. The touch signals (such as the first touch signal and the second touch signal) corresponding to the second wake-up operation (such as the first touch operation and the third touch operation) are collected at the first frequency or the second frequency.

By using this acquisition frequency conversion method, since the third and fourth frequencies are lower than the first and second frequencies, the power consumption of the solid-state buttons during the wake-up waiting process can be further reduced. When the user's wake-up behavior is detected, the acquisition frequency is immediately increased to ensure the smooth acquisition of the touch signal. Therefore, compared with a fixed acquisition frequency, the variable acquisition frequency can save more power consumption while ensuring the wake-up response, further improving the product's battery life.

It should be noted that the settings of the first frequency, the second frequency, the third frequency and the fourth frequency can be set according to actual needs, and the embodiments of the present application do not impose any limitation on this.

As shown in FIG. 10 , FIG. 10 shows a schematic flow chart of a method for waking up an electronic device by taking the first frequency=1 Hz, the second frequency=2 Hz, the third frequency=0.25 Hz, and the fourth frequency=1 Hz as an example.

Exemplarily, in the shipping mode, the acquisition frequency of the first sensor is first 0.25Hz, and the corresponding average acquisition current is 5uA. When the user's second touch operation is detected, the acquisition frequency is increased to 1Hz to collect the first touch signal corresponding to the first touch operation. Compared with the fixed 1Hz acquisition frequency, the average acquisition current corresponding to the 1Hz acquisition frequency is greater than 20uA. Therefore, according to the calculation of 180 days in the shipping mode, the electronic device in the embodiment of the present application can save at least: (20uA-5uA)*180 days*24 hours=64800uAh=64.8mAh of electricity, thereby reducing the power consumption required for solid-state buttons in the shipping mode by more than 75%.

It can be seen that compared with a fixed acquisition frequency, the variable frequency acquisition frequency method in the embodiment of the present application can further save power consumption while ensuring performance and response speed.

In some embodiments, when the electronic device is in a low power consumption mode such as shipping mode or shutdown mode, a user may accidentally touch the power button, which may easily cause the microcontroller of the solid-state button to mistakenly believe that the user needs to wake up the electronic device.

Therefore, in order to prevent the electronic device from being awakened by an accidental touch by the user, if the user needs to wake up the electronic device, the touch operation on the power button needs to have a certain touch duration.

For example, the touch duration for waking up the electronic device from the shipping mode may be the first touch duration. Exemplarily, the first touch duration may be 10 seconds. And the touch duration for waking up the electronic device from the shutdown mode may be the second touch duration. Exemplarily, the second touch duration may be 20 seconds.

It should be noted that the first touch duration and the second touch duration can be configured according to actual product requirements, and the embodiment of the present application does not impose any limitation on the first touch duration and the second touch duration.

Therefore, after the microcontroller of the solid-state key receives the first touch signal corresponding to the first touch operation collected by the first sensor, it is necessary to further determine whether the first touch signal meets the first touch duration. If it meets, it is determined that the first touch operation of the user this time is an effective wake-up behavior, and then the working mode of the electronic device is switched from the shipping mode to the running mode in response to the first touch signal corresponding to the first touch operation. If it does not meet, it is determined that the first touch operation of the user this time is not an effective wake-up behavior, and the working mode of the electronic device is not switched, and the electronic device continues to operate in the shipping mode.

Exemplarily, if the first touch signal includes n consecutive touch signal values, where n=10, it means that the first touch signal satisfies the first touch duration.

In addition, in addition to satisfying the first touch duration, the first touch signal and the n consecutive touch signal values also need to satisfy the first preset requirement. The first preset requirement is determined according to the type of the first sensor. For example, if the first sensor is a pressure sensor, the first preset requirement may be a first pressure threshold. That is, in order to prevent accidental touches, only when the user's pressure on the power button exceeds a certain pressure threshold can it be determined that the touch signal value is a signal for indicating that the electronic device is to be awakened from the shipping mode.

That is to say, in the embodiment of the present application, the first touch signal needs to include n consecutive touch signal values that meet the first preset requirement (such as the first pressure threshold) to indicate that the user's touch operation is an effective wake-up behavior, and then the microcontroller of the solid-state button switches the working mode of the electronic device from the shipping mode to the operating mode in response to the first touch signal. The switching of the working mode of the electronic device can be achieved by the microcontroller of the solid-state button sending a level control signal to the power management module PMU of the electronic device through the level control signal.

Similarly, when the microcontroller of the solid-state button receives the second touch signal corresponding to the third touch operation collected by the first sensor, it is also necessary to further determine whether the second touch signal meets the second touch duration. If satisfied, it is determined that the third touch operation of the user this time is an effective wake-up behavior, and then the working mode of the electronic device is switched from the shutdown mode to the running mode in response to the second touch signal corresponding to the third touch operation. If not satisfied, it is determined that the third touch operation of the user this time is not an effective wake-up behavior, and the working mode of the electronic device is not switched, and the electronic device continues to operate in the shutdown mode.

Exemplarily, if the second touch signal includes m consecutive touch signal values, where m=20, it means that the second touch signal satisfies the second touch duration.

At the same time, in addition to satisfying the second touch duration, the second touch signal and the m consecutive touch signal values also need to satisfy a second preset requirement. The second preset requirement is also determined according to the type of the first sensor. For example, if the first sensor is a pressure sensor, the second preset requirement may be a second pressure threshold.

That is, in order to prevent accidental touches, only when the user's pressure on the power button exceeds a certain pressure threshold can it be determined that the second touch signal value is a signal for instructing to wake up the electronic device from the shutdown mode.

That is to say, in the embodiment of the present application, the second touch signal needs to include m consecutive touch signal values that meet the second preset requirement (such as the second pressure threshold) to indicate that the user's third touch operation is an effective wake-up behavior, and then the microcontroller of the solid-state button switches the working mode of the electronic device from the shutdown mode to the operating mode in response to the second touch signal. The switching of the working mode of the electronic device can be achieved by the microcontroller of the solid-state button sending a level control signal to the power management module PMU of the electronic device through the level control signal.

As shown in FIG. 11 , the specific process of switching the working mode of the electronic device to the operating mode according to the first touch signal and the second touch signal is shown.

That is, in the shipping mode, after the microcontroller collects the first touch signal corresponding to the first touch operation according to the first frequency (such as 1Hz), if the first touch signal includes n consecutive touch signal values that meet the first preset requirement, the microcontroller switches the working mode of the electronic device from the shipping mode to the running mode. Otherwise, the microcontroller regards the first touch operation as a false touch by the user or the awakening behavior is invalid, and the microcontroller does not switch the working mode of the electronic device.

In shutdown mode, after the microcontroller collects the second touch signal corresponding to the third touch operation according to the second frequency (such as 2Hz), if the second touch signal includes m consecutive touch signal values that meet the second preset requirement, the microcontroller switches the working mode of the electronic device from shutdown mode to running mode. Otherwise, the microcontroller regards the third touch operation as a false touch by the user or the wake-up behavior is invalid, and the microcontroller does not switch the working mode of the electronic device.

It should be noted that the above-mentioned first preset requirement (such as the first pressure threshold) and the second preset requirement (such as the second pressure threshold) can be set according to actual needs, and the embodiments of the present application do not impose any restrictions on this. In some embodiments, the first preset requirement (such as the first pressure threshold) can be equal to the second preset requirement (such as the second pressure threshold).
