Abstract

A device status acquisition method, an electronic device and a computer-readable storage medium relate to the field of terminal technology. The accuracy of the accessory status can be improved. A first electronic device determines the first status of a second electronic device based on data collected by a sensor, and initiates a PING detection to the second electronic device. The first status is a removal status of the second electronic device from an adsorbable area or an adsorption status of the second electronic device adsorbed to the adsorbable area. If the PING fails, the real-time status of the second electronic device is determined to be a removal status. If the PING succeeds, the real-time status of the second electronic device is determined to be an adsorption status. The first electronic device first preliminarily obtains the first status of the second electronic device based on the sensor data collected by the sensor, and then initiates a PING detection to the second electronic device, and obtains a more accurate device status of the second electronic device through the result of the PING detection.

Description

Device state acquisition method, electronic device and computer readable storage medium

Technical Field

The embodiment of the application relates to the technical field of terminals, in particular to a device state acquisition method, electronic equipment and a computer readable storage medium.

Background

Some electronic devices may have accessories for matching use, for example, electronic devices such as tablet computers may have accessories such as handwriting pens that can be matched for use. The accessory may be attached to the electronic device, for example by magnetic force, in which case the state of the accessory relative to the electronic device may be referred to as an attached state. The accessory may also be lifted off by the user from the attached state, leaving the electronic device, at which point the state of the accessory relative to the electronic device may be referred to as the lifted-off state.

Currently, the electronic device can use a sensor module (including a controller and a magnetic force sensor for collecting magnetic force data) to detect the above-mentioned adsorption state and the removal state. The sensor module is used for detecting real-time magnetic force between the electronic equipment and the accessory and comparing the acquired real-time magnetic force with a pre-recorded magnetic force threshold value. If the real-time magnetic force is smaller than or equal to the magnetic force threshold value, the accessory is possibly taken away from the electronic device, namely, the accessory is switched from the adsorption state to the take-away state, and the sensor module reports a take-away event to the tablet computer. Otherwise, if the real-time magnetic force is greater than the magnetic force threshold value, the accessory is likely to be adsorbed on the electronic device, that is, the accessory is switched from the taken-off state to the adsorption state, and the sensor module reports an adsorption event to the tablet computer. The electronic device can respond to the event type reported by the sensor module and execute the corresponding event processing flow.

The electronic equipment relies on the scheme of magnetic force data acquisition accessory state that sensor module gathered, receives external environment's magnetic field variation influence easily, leads to the accuracy of acquired accessory state to reduce.

Disclosure of Invention

The embodiment of the application provides a device state acquisition method, electronic equipment and a computer readable storage medium, which are used for solving the technical problem that the accuracy of an accessory state determined by magnetic force data acquired by a magnetic force sensor is low, and further acquiring a more accurate accessory state by combining a PING detection result on the basis of the data acquired by the sensor.

In order to achieve the above purpose, the embodiment of the present application adopts the following technical scheme:

In a first aspect, an apparatus state acquiring method is provided, where the apparatus state acquiring method is applied to a first electronic apparatus, and the acquired apparatus state refers to a relative state between a second electronic apparatus and the first electronic apparatus. The first electronic device and the second electronic device may be used together, or the second electronic device may be an accessory of the first electronic device. For example, the first electronic device may be a tablet computer or a notebook computer, and the second electronic device may be an accessory of the tablet computer or the notebook computer, such as a stylus. The surface of the first electronic device is provided with a adsorbable region that can be used to adsorb the second electronic device. For example, an adsorbable region is provided on the side surface of the tablet computer, a magnetic attraction device is provided in the adsorbable region, and a device capable of being attracted by the magnetic attraction device is provided in the stylus pen correspondingly, so that the stylus pen can be attracted to the adsorbable region when the stylus pen is attached to the adsorbable region on the side surface of the tablet computer.

In other cases, the first electronic device may also be a wireless charger, such as a vehicle-mounted magnetic charger, and the second electronic device may be an electronic device such as a tablet computer, a notebook computer, a mobile phone, a smart watch, a bracelet, an earphone, etc. that is matched with the wireless charger, and these second electronic devices may also be adsorbed to the adsorbable area on the surface of the first electronic device.

The electronic equipment is provided with a sensor at a position corresponding to the adsorbable region and is used for acquiring sensor data of the adsorbable region. For example, a magnetic force sensor is disposed in the adsorbable region for acquiring magnetic force data of the adsorbable region. The first electronic equipment is a flat plate, the second electronic equipment is a handwriting pen, and when the handwriting pen can be adsorbed on an adsorbable area on the surface of the flat plate through magnetic force, the magnetic force sensor arranged in the adsorbable area can collect magnetic force data of the adsorbable area, and the magnetic force data of the adsorbable area is used as magnetic force data between the flat plate and the handwriting pen.

After the first electronic device acquires the sensor data acquired by the sensor, the device state of the second electronic device is initially acquired based on the sensor data, and the device state is defined as a first state, wherein the first state may be a take-off state or an adsorption state. Considering that magnetic force data collected by the magnetic force sensor may be affected by an environmental magnetic field, only the first state determined by the magnetic force data may not accurately reflect the device state of the second electronic device.

Based on this, the electronic device is triggered by the first state of the second electronic device determined by the sensor, further confirming the device state. Considering that the second electronic device is adsorbed on the surface of the first electronic device, that is, when the second electronic device is in a real adsorption state, the first electronic device and the second electronic device can perform PING connection. On the contrary, if the second electronic device is not adsorbed on the surface of the first electronic device, the first electronic device cannot perform PING connection with the second electronic device. And a program for testing the network connection quantity during PING connection. PING is a service command that works at the application layer in a TCP/IP network architecture, mainly to send an internet message control protocol Echo request message to a specific destination host, test whether the destination station is reachable and understand its relevant status.

The first electronic device initiates PING detection for wireless charging to the second electronic device in order to further verify the accuracy of the acquired first state of the second electronic device. Only if the second electronic device is in a real adsorption state, the PING detection result may be a PING success, otherwise, the PING detection result is a PING failure. The first electronic device determines the real-time state of the second electronic device according to the PING detection result. If PING fails, determining that the real-time state of the second electronic equipment is a take-off state. Otherwise, if the PING is successful, determining that the real-time state of the second electronic equipment is the adsorption state.

In the above method for acquiring a device state provided by the embodiment of the present application, a first electronic device initially acquires a first state of a second electronic device based on sensor data acquired by a sensor, and in order to verify accuracy of the first state, the first electronic device initiates PING detection to the second electronic device, and acquires a more accurate device state of the second electronic device through a PING detection result. In this way, subsequent control of the first electronic device based on the device status of the second electronic device, such as wireless charging, data transfer, etc., is more efficient. Based on the first state of the second electronic device determined by the sensor data collected by the sensor in the existing scheme, the first electronic device starts the operation of determining the device state of the second electronic device through PING detection when receiving the first state reported by the sensor, does not need to continuously initiate PING detection, and can acquire more accurate device state.

In a possible implementation manner of the first aspect, the first electronic device to which the provided device state obtaining method is applied may be a tablet computer or a notebook computer, and the second electronic device corresponding to the first electronic device may be an accessory of the first electronic device, where the accessory includes a handwriting pen.

Or in other cases, the first electronic device may be a wireless charger and the second electronic device includes at least one of a tablet computer, a notebook computer, a cell phone, and a wearable device. The wearable device herein may be a smart watch, a bracelet, a wireless headset, etc.

In a possible implementation manner of the first aspect, a scheme for implementing PING detection is further defined. Specifically, a first wireless charging chip is mounted in the first electronic device, and the first wireless charging chip comprises a transmitting coil. The second electronic device includes a second wireless charging chip including a receiving coil. The transmitting coil of the first wireless charging chip can transmit electromagnetic waves to the receiving coil of the second wireless charging chip, so that the first wireless charging chip can wirelessly charge the second wireless charging chip, and the first electronic device can wirelessly charge the second electronic device. Of course, the first wireless charging chip may perform data transmission in addition to the function of wirelessly charging the second wireless charging chip. One precondition that the first wireless charging chip performs wireless charging for the second wireless charging chip is that the second electronic device is adsorbed on the adsorbable area on the surface of the first electronic device. The first wireless charging chip can initiate PING detection to the second wireless charging chip only when the second electronic device is adsorbed on the adsorbable region of the surface of the first electronic device.

In a possible implementation manner of the first aspect, it is considered that if the first wireless charging chip in the first electronic device is to perform PING detection with the second wireless charging chip, the first wireless charging chip needs to be powered on first, and then the PING detection can be performed on the second wireless charging chip after the first wireless charging chip is powered on. Before the first wireless charging chip is powered on, if the first wireless charging chip is in a power-down state, the first wireless charging chip is directly controlled to be powered on, and the influence is hardly caused. If the first wireless charging chip is in a power-on state, especially in a charging state before power-on, the first wireless charging chip needs to be powered down and then powered up, and in this case, the originally ongoing charging state may be suspended, that is, the charging is stopped, and the second electronic device displayed on the first electronic device is powered up after the charging is stopped, so that the user experience is poor.

If the first state determined based on the data collected by the sensor is the adsorption state, the state of the second electronic device should be the taking-off state before that, the first wireless charging chip can not wirelessly charge the second wireless charging chip in the taking-off state, and in this case, the first wireless charging chip is directly controlled to be electrified and PING detection is performed, and no charging interruption is caused.

If the first state determined based on the data collected by the sensor is the take-off state, the state of the second electronic device should be the adsorption state before that, and the first wireless charging chip is likely to perform wireless charging for the second wireless charging chip in the adsorption state. In this case, the first wireless charging chip is directly controlled to power up and perform PING detection, which is likely to cause suspension of wireless charging which is performed originally, resulting in poor user experience.

Based on this, in the device state acquiring method provided in the present embodiment, for the case that the first state of the second electronic device is determined to be the taken-off state based on the data acquired by the sensor, the determination as to whether the first wireless charging chip is in the charging state is further increased, so as to reduce the case of the disconnection as much as possible.

Specifically, the step of controlling, by the first electronic device, the first wireless charging chip to initiate PING detection to the second wireless charging chip may include: if the first state of the second electronic device is the taken-off state, which is determined based on the data collected by the sensor, whether the first wireless charging chip is in the charging state can be judged first.

And a flag register is arranged in the first electronic equipment, and a charging state flag bit is arranged in the flag register and used for recording the charging state of the first wireless charging chip. The charging state flag bit is determined according to a control instruction that the first electronic device controls the first wireless charging to the second wireless charging, and does not necessarily truly reflect the charging state of the first wireless charging chip. After the first electronic device receives the state event reported by the sensor module and determines that the state event is a take-off event, whether the first wireless charging chip is in a charging state or not can be judged based on the charging state flag bit.

If the first electronic device determines that the first wireless charging chip is not in the charging state, the first electronic device can directly power on the first wireless charging chip, then control the first wireless charging chip to initiate PING detection to the second wireless charging chip, and further verify whether the device state of the second electronic device is a real taking-out state according to the PING detection result.

If the first electronic device determines that the first wireless charging chip is in a charging state, in order to avoid possible charging interruption, the first electronic device does not verify the device state of the second electronic device by initiating PING detection, but verifies the device state of the second electronic device by other means. For example, the electronic device may verify whether the device status of the second electronic device is a real taken-off status through the output power of the first wireless charging chip or other electrical parameters.

According to the equipment state acquisition method provided by the embodiment, for the situation that the first state determined by the data acquired by the sensor is the taken-off state, the adaptive equipment state acquisition scheme is selected according to the charging state of the first wireless charging chip, so that the situation that the charging is broken and the power consumption is increased possibly is avoided.

In a possible implementation manner of the first aspect, for a case where the first wireless charging is in a charging state, the real device state is obtained according to an output power of the first wireless charging chip.

In the service flow of wireless charging for the second electronic device, the first wireless charging chip is used for outputting power to the second electronic device, and the second wireless charging chip of the second electronic device is used for receiving the power output by the first wireless charging chip and is the most dominant or unique power receiving end. When the first wireless charging chip does not perform wireless charging for the second wireless charging chip, or the first wireless charging chip is in an idle state which is not in a charging state, the idle power in the idle state can be basically equal to the charging link loss power. That is, the output power of the first electronic device when in the charging state is greater than the output power when not in the charging state, and the real-time state of the device can be further verified by combining the output power.

Specifically, if the first electronic device determines that the first wireless charging chip is in the charging state, the output power of the first wireless charging chip is obtained, and if the output power of the first wireless charging chip is less than or equal to a predefined power threshold, the real-time state of the second electronic device is determined to be the taking-off state. And if the output power of the first wireless charging chip is larger than the power threshold value, determining that the real-time state of the second electronic equipment is the adsorption state.

In a possible implementation manner of the first aspect, the power threshold is further defined as an idle power when the first wireless charging chip is not in a charging state.

In a possible implementation manner of the first aspect, after the first electronic device determines the real-time state of the second electronic device according to the data collected by the sensor, the PING detection result, or the output power of the first wireless charging chip, the subsequent control flow may be further continued. For example, if the real-time state of the second electronic device is the adsorption state, the first electronic device may control the first wireless charging chip to charge the second wireless charging chip. In this way, the second electronic device can be ensured to be in a state where a high amount of power is available as much as possible.

Of course, in the implementation, the first electronic device may also acquire the real-time electric quantity of the second electronic device first, and under the condition that it is determined that the real-time electric quantity of the second electronic device does not reach the maximum electric quantity and the remaining electric quantity of the first electronic device meets the charging requirement, the first electronic device performs wireless charging for the second electronic device through the first wireless charging chip. Because the acquired equipment state of the second electronic equipment is high in accuracy, the follow-up control flow is not easy to be wrong, and the equipment operation efficiency is improved.

In a possible implementation manner of the first aspect, an internal implementation principle of the device state acquisition method is provided. Specifically, the first electronic device includes a first controller, and the first controller may execute the device state acquiring method and the interaction control method of the first electronic device and the second electronic device provided in this embodiment. The first electronic device further comprises a sensor module, and the sensor module comprises a second controller and a magnetic force sensor. The magnetic force sensor can collect magnetic force data, the collected magnetic force data are sent to the second controller, and the second controller preliminarily determines the first state of the second electronic equipment according to the magnetic force data collected by the magnetic force sensor.

Specifically, the second controller reports a state event corresponding to the first state to the first controller based on magnetic force data acquired by the magnetic force sensor. The first controller receives the state event reported by the second controller and initiates PING detection to the second electronic device. In actual implementation, the first controller sends a PING connection instruction to the first wireless charging chip, and the first wireless charging chip initiates PING detection to the second wireless charging chip of the second electronic device.

In a possible implementation manner of the first aspect, the step of reporting, by the second controller, a state event corresponding to the first state based on magnetic force data collected by the magnetic force sensor specifically includes:

The second controller stores a magnetic threshold value in advance, wherein the magnetic threshold value indicates critical magnetic data when the equipment state of the second electronic equipment is switched from the taking-off state to the adsorption state or critical magnetic data when the equipment state is switched from the adsorption state to the taking-off state.

The second controller receives magnetic force data acquired by the magnetic force sensor in real time, and then determines a state event corresponding to the first state according to the magnetic force data and a predefined magnetic force threshold value. Specifically, if the second controller determines that the magnetic force data is greater than or equal to the magnetic force threshold value, a state event corresponding to the adsorption state is generated and reported to the first controller. Otherwise, if the second controller determines that the magnetic force data acquired by the magnetic force sensor in real time is smaller than the magnetic force threshold value, a state event corresponding to the take-off state is generated and reported to the first controller.

It should be noted that, the first state corresponding to the state event generated by the second controller is only the initially determined device state, and the more accurate device state of the second electronic device may be obtained only after further verification and determination by the first controller.

Detailed Description

Exemplary embodiments of the present application will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present application are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

For the sake of easy understanding, a part of common technical knowledge related to the embodiments of the present application will be described.

As shown in fig. 1 and fig. 2, the first electronic device 100 and the second electronic device 200 may be used together, where the surface of the first electronic device 100 is provided with an adsorbable region, and the second electronic device 200 may be adsorbed on the adsorbable region on the surface of the first electronic device 100. The first electronic device 100 and the second electronic device 200 may perform unidirectional or bidirectional data transmission therebetween.

In particular, the second electronic device 200 may be an accessory of the first electronic device 100. For example, the first electronic device 100 may be a tablet computer or a notebook computer, and the second electronic device 200 may be an accessory of the first electronic device 100 such as a stylus. In some cases, the first electronic device 100 may also be a wireless charger, such as an on-board wireless charger, the second electronic device 200 may be a tablet computer, a notebook computer, a mobile phone, or a wearable device, and the wearable device may be a bracelet, a smart watch, an earphone, or the like that can be wirelessly charged through the wireless charger. In this embodiment, the first electronic device 100 is mainly used as a tablet computer, and the second electronic device 200 is used as a handwriting pen for example, to explain a specific implementation process of the device status acquisition method provided in the embodiment of the present application.

As shown in fig. 1 and 2, the first electronic device 100 is a tablet computer, and the second electronic device 200 is an accessory of the first electronic device, such as a stylus. As shown in (a) and (b) in fig. 1, the stylus is in an adsorption state with respect to the tablet computer. The adsorption state refers to that the handwriting pen is fixed close to the surface of the tablet computer through magnetic force or other types of suction. Under other conditions, the surface of the tablet personal computer can be provided with a buckle or a connecting wire, and the handwriting pen can be fixed close to the surface of the tablet personal computer through the buckle or the connecting wire. It should be noted that, in general, the stylus is attached to a fixed adsorbable area on the surface of the tablet computer, instead of any area, and the fixed adsorbable area may provide the magnetic force or other force required for stylus attachment. For example, the adsorbable region may be a side region of a tablet computer.

As shown in fig. 2, the first electronic device 100 includes a first wireless charging chip 110, and the second electronic device 200 includes a second wireless charging chip 210, where the first wireless charging chip 110 is configured to wirelessly charge the second wireless charging chip 210. When the second electronic device 200 is attached to the first electronic device 100, the first electronic device 100 performs wireless charging for the second electronic device 200 through electromagnetic coupling between the first wireless charging chip 110 and the second wireless charging chip 210.

As shown in fig. 1 (a), the tablet computer may obtain the real-time electric quantity of the stylus pen, and display an electric quantity mark of the stylus pen on the interface (as shown in a in fig. 1). The tablet computer detects that the electric quantity of the handwriting pen does not reach the maximum electric quantity, can charge the handwriting pen, and displays the prompt message on the interface when the handwriting pen is charged. For example, the tablet computer may display a charge flag on the charge flag of the stylus, or the tablet computer may also display a prompt message such as "charge the stylus" on the interface.

As shown in fig. 1 (b), when the tablet computer detects that the electric quantity of the handwriting pen reaches the maximum electric quantity, the tablet computer is fully charged, and the charging of the handwriting pen can be stopped. In addition, the tablet computer may cancel the charging mark displayed in advance on the interface, or display a prompt message (as shown in B in fig. 1) such as "the handwriting pen is full" on the interface by a popup frame, so as to prompt the user that the handwriting pen is full. When the tablet computer detects that the handwriting pen is in an adsorption state and is fully charged, an instruction for entering a low-power-consumption mode can be sent to the handwriting pen, so that the handwriting pen is instructed to be switched to the low-power-consumption mode, and power consumption is reduced. In the low power consumption mode, the handwriting pen does not receive and process other external instructions until the handwriting pen receives the instruction for exiting the low power consumption mode sent by the tablet personal computer, and the handwriting pen can exit the low power consumption mode and enter the normal working mode.

As shown in fig. 3 (a) and (b), the stylus is in a removed state with respect to the tablet computer. The taking-off state means that the handwriting pen is not adsorbed on the surface of the tablet personal computer through magnetic force. As shown in fig. 3 (a), the stylus is held by a user, and a touch operation is applied to the touch screen of the tablet computer. In this case, even if the pen tip of the stylus is in contact with the surface of the tablet computer, the tablet computer determines the state of the stylus as the taken-off state.

As shown in fig. 3 (b), the stylus is not adsorbed on the surface of the tablet computer, the pen tip of the stylus does not apply touch operation on the touch screen of the tablet computer, and a distance exists between the stylus and the tablet computer, so that the tablet computer can determine the state of the stylus as a taken-off state. The handwriting pen is in a take-off state, data transmission can be carried out between the handwriting pen and the tablet personal computer through a near field communication mode, and the near field communication mode can comprise Bluetooth communication or wireless network communication. If it is to be ensured that the stylus can transmit information with the tablet computer, the distance between the stylus and the tablet computer should meet the distance required by near field communication. If the distance between the handwriting pen and the tablet computer is larger than the distance required by near field communication, the handwriting pen cannot transmit information with the tablet computer, and the tablet computer can determine that the handwriting pen is in an abnormal state or a disconnection state.

Continuing with fig. 2, the tablet is equipped with a sensor module 120, and the sensor module 120 may be mounted near the adsorbable region of the tablet surface to collect sensor data for that region. In particular, the sensor module 120 may include a controller and a magnetic force sensor for collecting magnetic force data, such as magnetic flux, between the tablet and stylus. And the controller is internally provided with a magnetic threshold value of the adsorption state and the taking-off state of the handwriting pen in advance, and the real-time state of the handwriting pen is judged according to the magnetic data acquired by the magnetic sensor and the magnetic threshold value. For example, if the magnetic force data is greater than or equal to the magnetic force threshold value, the stylus pen is determined to be in an adsorption state. If the magnetic force data is smaller than the magnetic force threshold value, judging that the handwriting pen is in a take-off state. Of course, the description is simplified here, and in a practical solution, the magnetic force sensor is not one magnetic force data of a single direction, but multi-directional magnetic force data, such as triaxial magnetic force data, etc. The controller may compare magnetic force data of three axes when comparing, and then combine a series of calculations to obtain the real-time status of the stylus pen, which will not be described in detail herein.

Under other conditions, for example, when the handwriting pen is fixed on the tablet computer through a connecting piece such as a buckle, a sensor in the sensor module can be replaced by a pressure sensor arranged on the surface of the tablet computer, and the pressure sensor can collect the pressure of the handwriting pen attached to the surface of the tablet computer. The controller compares the pressure data collected by the pressure sensor with the pressure threshold value to judge the real-time state of the stylus, and the detection of the state of the stylus can be realized.

In addition, still be equipped with first wireless chip that charges in the panel computer, be equipped with transmitting coil on this first wireless chip that charges. Correspondingly, the handwriting pen is provided with a second wireless charging chip, and the second wireless charging chip is provided with a receiving coil. The transmitting coil of the first wireless charging chip transmits electromagnetic waves, and the receiving coil of the second wireless charging chip receives the electromagnetic waves, so that the tablet personal computer can perform wireless charging for the handwriting pen. If the tablet personal computer determines that the real-time state of the handwriting pen is the adsorption state, acquiring electric quantity data of the handwriting pen, and judging whether the handwriting pen needs to be charged or not. If the handwriting pen is determined to be charged, the first wireless charging chip is controlled to emit electromagnetic waves to the second wireless charging chip, so that the handwriting pen is charged.

For the scheme of acquiring the handwriting state based on the magnetic force data acquired by the magnetic force sensor, the magnetic force data acquired by the magnetic force sensor is easily influenced by the magnetic field of the surrounding environment, such as the strong magnetic environment, so that the accuracy of the determined handwriting state is reduced.

Based on the above, the embodiment of the application provides an equipment state acquisition method which is applied to first electronic equipment. The surface of the first electronic device is provided with an adsorbable region, and the second electronic device can be adsorbed on the adsorbable region of the surface of the first electronic device. The first electronic equipment determines the first state of the first and second electronic equipment based on the data acquired by the sensor, and further equipment state detection flow is added on the basis of the first state, so that the accuracy of the acquired equipment state is improved. The applied first electronic device may include a personal computer (Personal Computer, PC), a tablet computer, a notebook computer, a portable computer (e.g., a mobile phone), a wearable electronic device (e.g., a smart watch), an augmented Reality (Augmented Reality, AR) \virtual Reality (VR) device, a vehicle-mounted computer, etc., and the following embodiments do not limit the specific form of the first electronic device in particular. In this embodiment, the first electronic device may be a tablet computer, and the second electronic device may be a stylus.

Fig. 4 is a schematic flow chart of a method for acquiring a device status according to an embodiment of the present application. The provided equipment state acquisition method mainly comprises the following steps:

step S401, determining a first state of the second electronic device based on the data collected by the sensor, and initiating PING detection for wireless charging to the second electronic device.

Step S402, if the PING fails, determining that the real-time status of the second electronic device is the taken-off status.

Step S403, if PING is successful, determining that the real-time status of the second electronic device is the adsorption status.

The first electronic device is internally provided with a controller, and the controller can execute the device state acquisition method. For ease of description, the controller may be defined as a first controller. The first controller may be a main controller of the first electronic device, and controls an interaction flow between the first electronic device and the second electronic device.

As further shown in fig. 2, a sensor module is disposed in the first electronic device, where the sensor module may collect sensor data on the surface of the first electronic device, report the sensor data to a controller of the first electronic device, and determine, by the electronic device, a device state of the second electronic device according to the sensor, where the obtained device state is a predicted state, and may be defined as a first state, where the first state may be consistent with or inconsistent with a true device state of the second electronic device.

In particular, the sensor module may comprise a magnetic force sensor, which may collect magnetic force data within a range around, for example magnetic force data of the first electronic device surface. The sensor module may also include a controller, which may be defined as a second controller for ease of distinction.

In the implementation, the second controller may report a state event corresponding to the first state based on magnetic force data collected by the magnetic force sensor, and the first controller of the first electronic device receives the state event reported by the second controller and initiates PING detection for wireless charging to the second electronic device.

Fig. 5 shows a second flowchart of the provided device status acquisition method. The user adsorbs/takes the second electronic equipment off the adsorbable region on the surface of the first electronic equipment, the magnetic force of the adsorbable region on the surface of the first electronic equipment can be changed, the magnetic force sensor of the sensor module collects magnetic force data, the magnetic force change is detected, the second controller compares the magnetic force data with a magnetic force threshold value, a state event is obtained, and the state event is reported to the first controller of the first electronic equipment.

Specifically, the status events may include an adsorption event and a take-off event. The adsorption event is used for indicating that the real-time state of the second electronic device relative to the first electronic device is an adsorption state, and the taking-off event is used for indicating that the real-time state of the second electronic device relative to the first electronic device is a taking-off state. The adsorption event indicates that the real-time state of the second electronic device is the adsorption state with respect to the first electronic device, which is understood to mean that the real-time state of the second electronic device is switched from the take-off state to the adsorption state with respect to the first electronic device. Correspondingly, the take-off event indicates that the real-time state of the second electronic device relative to the first electronic device is taken off, which can be understood as that the real-time state of the second electronic device relative to the first electronic device is switched from the adsorption state to the take-off state.

And the second controller is internally pre-stored with magnetic force threshold values obtained by statistics when the second electronic equipment is in an adsorption state and a take-off state respectively. The magnetic force threshold value is used for indicating a magnetic force threshold value when the real-time state of the second electronic device relative to the first electronic device changes. The magnetic force sensor in the sensor module can periodically acquire real-time magnetic force data, and the second controller compares the acquired magnetic force data with a magnetic force threshold value of a pre-stored corresponding adsorption state and a corresponding take-off state to obtain a state event.

For example, if the magnetic force data is smaller than the magnetic force threshold value, the second controller determines that the second electronic device is switched from the adsorption state to the take-off state, and determines that the occurred state event is the take-off event. At this time, the second controller reports the take-off event to the first controller.

On the other hand, if the magnetic force data is greater than or equal to the magnetic force threshold value, the second controller determines that the second electronic device is switched from the take-off state to the adsorption state, and determines that the occurred state event is the adsorption event. At this point, the second controller reports the adsorption event to the first controller.

Of course, in other cases, other ways of acquiring the state event acquired by the first electronic device are also possible. For example, the sensor of the sensor module is a pressure sensor arranged in the adsorbable area, and the pressure sensor can also collect pressure data in real time, and the second controller judges whether to report a state event.

In other embodiments, the first electronic device may determine whether to take the electronic device out of the Control Error (CE) packet. The CE packet is a data packet for recording an error control instruction in the first electronic device. The CE packets may be divided into a fast CE packet and a slow CE packet, which have different recording periods, respectively. The second electronic device periodically sends CE packets to the first electronic device while the second electronic device is attached to the first electronic device. If the first electronic device does not receive the CE packet sent by the second electronic device in the appointed period, the first electronic device indicates that a take-off event occurs, and the device state of the second electronic device is switched to the take-off state. Therefore, the first electronic device can also acquire the device state of the second electronic device according to the contracted period and the packet sending state of various CE packets. The scheme of judging the device state of the second electronic device based on the period of the CE packet is relatively time-lag, and may not be able to acquire the device state of the second electronic device in time.

As shown in fig. 1, when the second electronic device is in an adsorption state relative to the first electronic device, the second electronic device is attached to the adsorbable region on the surface of the first electronic device. In this case, the first electronic device may make a PING connection with the second electronic device. PING, PACKET INTERNET Groper, is a program for testing network connectivity, an internet packet explorer. PING is a service command that works at the application layer in the TCP/IP network architecture, mainly to send an internet message control protocol (Internet Control Message Protocol, ICMP) Echo request message to a specific destination host, and to test whether the destination station is reachable and knows its relevant status. The PING referred to in this embodiment may refer to a PING connection for wireless charging. Before the first electronic equipment carries out wireless charging for the second electronic equipment, PING connection can be initiated, the first electronic equipment generally initiates PING connection to the second wireless charging chip of the second electronic equipment through an internal first wireless charging chip for wireless charging, and PING can be successfully performed only when the first electronic equipment and the second electronic equipment are in adsorption contact. In other cases, the PING detection may be implemented by other near field communication detection devices or chips capable of performing PING detection, which is not limited.

In the embodiment of the application, the second electronic device is attached to the adsorbable area on the surface of the first electronic device, that is, when the second electronic device is in a real adsorption state, the first electronic device and the second electronic device can be successfully connected by PING. If the first electronic device judges that the second electronic device is in the adsorption state, but the second electronic device is not in the adsorption state, the first electronic device cannot successfully realize PING connection with the second electronic device, and then PING failure can be caused.

Based on the foregoing analysis, in order to confirm whether the status event uploaded by the sensor module acquired by the first electronic device corresponds to a real device status, the first electronic device may initiate PING detection on the second electronic device, and detect whether the first electronic device and the second electronic device can successfully perform PING connection.

If the second electronic device is in a real adsorption state, the first electronic device and the second electronic device can perform PING successfully. If the second electronic device is in a real take-off state (i.e., the second electronic device is not in an adsorption state), the first electronic device and the second electronic device cannot perform PING successfully. That is, the second electronic device initiates the PING detection to the second electronic device in the real adsorption state, and if not, the PING detection results are PING success.

The first electronic device initiates PING detection to the second electronic device based on triggering of the state event reported by the sensor module, determines the real-time state of the second electronic device according to the PING detection result, and also verifies the accuracy of the state event reported by the sensor module.

In one case, assume that the status event reported by the sensor module is a take-off event. If the PING detection result is that the PING fails, the real-time state of the second electronic equipment is a real take-off state. Otherwise, if the PING detection result is that the PING is successful, the real-time state of the second electronic device is determined to be a real adsorption state, that is, the sensor module reports a false take-off event.

In another case, assume that the status event reported by the sensor module is an adsorption event. If the PING detection result is that PING is successful, determining that the real-time state of the second electronic equipment is a real adsorption state. Otherwise, if the PING detection result is that the PING fails, the real-time state of the second electronic device is a real take-off state. That is, the sensor module reports a false adsorption event.

According to the equipment state acquisition method provided by the embodiment of the application, after the first electronic equipment receives the state event reported by the sensor module, on the premise that PING is successful in a real adsorption state, the reliability degree of the state event is further verified by initiating PING detection to the second electronic equipment, so that the more accurate equipment state is acquired.

As shown in fig. 2, the first electronic device 100 is provided with a first wireless charging chip 110, and the second electronic device 200 is provided with a second wireless charging chip 210 corresponding to the first wireless charging chip, so that the first wireless charging chip can perform a function of initiating PING detection to the second electronic device in addition to a function of wireless charging for the second electronic device. That is, the first electronic device initiates PING detection to the second electronic device may be implemented through a first wireless charging chip in the first electronic device and a second wireless charging chip in the second electronic device.

In the implementation, the first electronic device responds to the state event reported by the sensor module, and the first wireless charging chip initiates PING detection to the second wireless charging chip of the second electronic device to further verify the credibility of the state event.

In some cases, it is considered that if the first wireless charging chip in the first electronic device performs PING detection with the second wireless charging chip, the first wireless charging chip needs to be powered on first, and the PING detection can be performed on the second wireless charging chip after the first wireless charging chip is powered on. Before the first wireless charging chip is powered on, if the first wireless charging chip is in a power-down state, the first wireless charging chip is directly controlled to be powered on, and the influence is hardly caused. If the first wireless charging chip is in a power-on state, particularly in a charging state before power-on, the first wireless charging chip needs to be powered down and then powered up, and in this case, the originally ongoing charging state may be suspended, that is, the charging is stopped, and the power is powered up after the charging is stopped, which may cause the power consumption of the first electronic device to increase.

On the basis of the embodiment, the embodiment of the application also provides another equipment state acquisition method. Compared to the device state acquiring method provided in the embodiment shown in fig. 4, this embodiment adds a process of selecting different processes according to whether the first electronic device is in a charging state, so as to reduce power consumption that may cause the first electronic device to be charged off, and improve accuracy of the acquired device state.

As shown in fig. 6, in the third embodiment of the present application, a flow chart of a device status acquisition method is provided, and the execution body may be a first controller in the first electronic device, and explain the main implementation procedure of the device status acquisition method from the perspective of the first controller. As shown in fig. 7, a fourth flowchart of the device status acquisition method according to the embodiment of the present application explains a main interaction process from the perspective of multiple execution subjects. Specifically, the provided equipment state acquisition method mainly comprises the following steps:

step S601, determining whether the status event reported by the sensor module is a take-off event.

If the status event reported by the sensor module is a take-off event, step S602 is executed to determine whether the first wireless charging chip is in a charging state.

The first controller of the first electronic device receives the state event reported by the sensor module, and the state event is divided into an adsorption event and a take-off event. If the state event reported by the sensor module is an adsorption event, the first wireless charging chip can be directly controlled to initiate PING detection to the second wireless charging chip, and whether the adsorption event reported by the sensor module is a trusted adsorption event is determined according to the PING detection result. For example, if the PING detection result is that PING is successful, the first electronic device may consider the reported adsorption event as a trusted adsorption event. Otherwise, if the PING detection result is that the PING fails, the first electronic device considers that the reported adsorption event is an unreliable adsorption event.

Before the first wireless charging chip is controlled to initiate PING detection to the second wireless charging chip, the first electronic device needs to control the first wireless charging chip to be electrified, and the PING detection can be initiated to the second wireless charging chip after the first wireless charging chip is electrified. In some cases, the control logic preconfigured in the first electronic device controls the first wireless charging chip to power down before the first electronic device controls the first wireless charging chip to power up. That is, the first wireless charging chip needs to be powered down and then powered up before PING detection can be initiated to the second wireless charging chip. If the first electronic device controls the first wireless charging chip to power down, the first wireless charging chip is charging the second wireless charging chip of the second electronic device, and the first electronic device controls the first wireless charging chip to power down, so that the wireless charging process of the first wireless charging chip for the second wireless charging chip is disconnected, and the charging is disconnected. The first electronic device switches the device state on the interface when detecting the charging failure or recharging after charging failure, for example, the charging frame disappears or the charging failure frame prompt is added. If the first electronic device switches the displayed device states frequently, the user perception is poor, and user experience is affected. Of course, in some cases, such as those where the stylus power is high, frequent recharging may also cause increased tablet power consumption.

In general, the adsorption event reported by the sensor module refers to that the second electronic device is switched from the take-off state to the adsorption state. That is, the first electronic device should be in the taken-off state before receiving the adsorption event reported this time. In the taken-off state, the first wireless charging chip of the first electronic device is not in a charging state for wirelessly charging the second electronic device. In this case, the first electronic device controls the first wireless charging chip to be powered down and then powered up, and initiates the PING detection operation to the second electronic device, so that no charging interruption is caused.

On the other hand, the take-off event reported by the sensor module means that the second electronic device is switched from the adsorption state to the take-off state. That is, before the first electronic device receives the take-off event reported by the sensor module, the previous state of the second electronic device should be an adsorption state, and in the adsorption state, the first wireless charging chip of the first electronic device may be in a charging state for wirelessly charging the second electronic device. In this case, the first electronic device controls the first wireless charging chip to be powered down and then powered up, and initiates a PING detection operation to the second electronic device, which may cause charging failure. That is, for some situations requiring the first wireless charging chip to be powered down and then powered up according to the control logic, if the first electronic device determines the credibility of the take-off event reported by the sensor module directly through the PING detection scheme, the second electronic device may be caused to be charged up, so that the power consumption of the first electronic device is increased.

Based on the above, the first electronic device may first determine whether the status event reported by the sensor module is a take-off event, and further determine whether the status event is in a charging state according to the take-off event, and respectively adopt different processing flows according to different situations in the charging state and not in the charging state.

Of course, if the status event reported by the sensor module is an adsorption event, a scheme of acquiring the real-time status of the second electronic device based on PING detection may be directly adopted, so as to save unnecessary computing operations. Of course, the first electronic device may follow the same processing flow for the adsorption event and the take-off event, so as to unify the control logic in the first electronic device, which is not limited. In this embodiment, a specific description is mainly made for the case that the status event reported by the sensor module is a take-off event.

And a flag register is arranged in the first electronic equipment, and a charging state flag bit is arranged in the flag register and used for recording the charging state of the first wireless charging chip. For example, if the charge status flag bit is 0, it indicates that the first wireless charging chip is not in the charge status. If the charge status flag bit is 1, it indicates that the first wireless charging chip is in a charge status. Of course, other recording modes are also possible, and are not limited.

The first electronic device determines that the second electronic device is in an adsorption state, determines that wireless charging is required to be performed on the second electronic device according to the real-time electric quantity of the second electronic device, controls the first wireless charging chip to charge the second wireless charging chip, and simultaneously marks the charging state at the position 1. The first electronic device determines that the second electronic device is in an adsorption state, and does not need to be wirelessly charged according to the real-time electric quantity of the second electronic device, or the first electronic device determines that the second electronic device is in a take-away state, and then the charging state flag position 0 can be set.

It should be noted that, the charging state flag bit herein is determined according to a control instruction that the first electronic device controls the first wireless charging to the second wireless charging, and does not necessarily truly reflect the charging state of the first wireless charging chip. For example, the first electronic device is in a process of controlling the first wireless charging chip to wirelessly charge the second wireless charging chip of the second electronic device, and the charging state is marked with the position 1. In the wireless charging process, if the user takes the second electronic device but the sensor module does not accurately report the take-off event, at this time, the first electronic device cannot control the first wireless charging chip to stop the operation of wireless charging for the second wireless charging chip because the first electronic device does not receive the take-off event, and then the charging state flag position 0 is not set. In the actual take-off state, the first wireless charging chip is not in the charging state, but the charging state flag bit may still be set to 1 and recorded as the charging state. In this case, the first electronic device needs to further determine in conjunction with the output power of the first wireless charging chip.

After the first electronic device receives the state event reported by the sensor module and determines that the state event is a take-off event, whether the first wireless charging chip is in a charging state or not can be judged based on the charging state flag bit. In one case, if the first electronic device determines that the first wireless charging chip is not in a charging state, a PING detection manner may be used to further determine the device state. In another case, if the first electronic device determines that the first wireless charging chip is in the charging state, the device state may be further determined according to the output power of the first wireless charging chip.

If the first wireless charging chip is not in the charging state, step S603 is performed to control the first wireless charging chip to power up.

In step S604, the first wireless charging chip is controlled to initiate PING detection to the second wireless charging chip.

If PING fails, step S605 is executed to determine that the real-time status of the second electronic device is the taken-off status.

If PING is successful, step S606 is executed to determine that the real-time status of the second electronic device is the adsorption status.

And the first electronic equipment firstly controls the first wireless charging chip to power on when determining that the first wireless charging chip is not in a charging state so as to control the first wireless charging chip to initiate PING detection to the second wireless charging chip. If the first wireless charging chip is in the power-down state, the first electronic device can directly control the first wireless charging chip to switch to the power-up state. If the first wireless charging chip is in a power-on state, and the initial control logic of the first electronic device indicates that the first electronic device must be switched from a power-off state to a power-on state to initiate PING detection, the first electronic device controls the first wireless charging chip to be switched to the power-on state and then to the power-on state before initiating PING detection. Of course, if the initial control logic of the first electronic device indicates that the first electronic device may directly initiate PING detection from the power-on state, or may directly initiate PING detection in the power-on state without an operation of switching to the power-down state.

The first electronic device controls the first wireless charging chip to initiate PING detection to the second wireless charging chip of the second electronic device, and determines the real-time state of the second electronic device according to the PING detection result. For example, if PING fails, the real-time state of the second electronic device is determined to be a take-off state, and the sensor module reports a real take-off event. If PING succeeds, determining that the real-time state of the second electronic equipment is an adsorption state, and reporting a false take-off event by the sensor module.

The specific implementation process of the first electronic device controlling the first wireless charging chip to initiate PING detection to the second wireless charging chip and determining the real-time state of the second electronic device according to the PING detection result may refer to the explanation about the corresponding content in the above embodiment, which is not repeated.

If the first wireless charging chip is in a charging state, step S607 is executed to obtain the output power of the first wireless charging chip;

in step S608, it is determined whether the output power of the first wireless charging chip is greater than the power threshold.

If the output power of the first wireless charging chip is not greater than the power threshold, step S605 is executed to determine that the real-time state of the second electronic device is the taken-off state.

If the output power of the first wireless charging chip is greater than the power threshold, step S606 is executed to determine that the real-time state of the second electronic device is the adsorption state.

In the service flow of wireless charging for the second electronic device, the first wireless charging chip is used for outputting power to the second electronic device, and the second wireless charging chip of the second electronic device is used for receiving the power output by the first wireless charging chip and is the most dominant or unique power receiving end. And combining the link power loss, and determining that the output power of the first wireless charging chip is as follows when the first wireless charging chip performs wireless charging for the second wireless charging chip according to the energy conservation principle: . Wherein Ptx represents the output power of the first wireless charging chip, prx represents the charging power of the second wireless charging chip, and Ploss represents the charging link loss power.

When the first wireless charging chip does not perform wireless charging for the second wireless charging chip, or the first wireless charging chip is in an idle state which is not in a charging state, the idle power in the idle state can be basically equal to the charging link loss power. The output power of the first wireless charging chip can be found as: The first electronic device may obtain no-load power when the first wireless charging chip is not in a charging state, as charging link loss power.

Based on the analysis, the first electronic device can use the idle power as a power threshold, and compare the output power of the first wireless charging chip with the power threshold to determine the charging power of the second wireless charging chip, and the charging power of the second wireless charging chip can accurately reflect the real charging state of the second electronic device.

The first wireless charging chip of the first electronic device can periodically collect and store electrical parameters, the collected electrical parameters generally comprise output current and output voltage, and the first electronic device can directly obtain the collected and stored electrical parameters without adding a process for collecting the electrical parameters. The first electronic device may obtain an output current and an output voltage of the first wireless charging chip, and through a power calculation formula: output power P (W) =output current I (I) ×output U voltage (V) to calculate the output power of the first wireless charging chip. Of course, considering that the output current and the output voltage are dynamically changed values, a single-number value acquired at each acquisition time may be used as a value involved in calculation, or an average value of a plurality of acquired values may be used as a value involved in calculation. Similarly, the second wireless charging chip of the first electronic device also periodically collects and stores the electrical parameters, so that the first electronic device can also obtain the charging current and the charging voltage collected and stored by the second wireless charging chip, and calculate the charging power of the second wireless charging chip.

Based on the analysis, the idle power of the first wireless charging chip in the first electronic device can be obtained through multiple experiments before the first electronic device leaves the factory. The specific process may include:

1. The data shown in table 1 were obtained by a plurality of experiments, respectively, and the collected data included: average voltage and average current of the first wireless charging chip, and average voltage and average current of the second wireless charging chip. Multiple experiments include a charged state and an uncharged state to record electrical parameters in different states, respectively.

TABLE 1

2. And calculating the output power of the first wireless charging chip according to the average voltage and the average current of the first wireless charging chip. And calculating the charging power of the second wireless charging chip according to the average voltage and the average current of the second wireless charging chip.

3. The analysis may obtain, for the experimental data (e.g., experimental data corresponding to the number 11 in table 1) obtained in the uncharged state, that the charging power of the second wireless charging chip is 0, and then the output power of the first wireless charging chip may be directly used as the no-load power. The difference power between the first wireless charging chip and the idle power is equal to 0. For each experimental data (such as experimental data corresponding to serial numbers 1-10 in table 1) obtained in the charging state, the difference between the output power and the idle power of the first wireless charging chip is greater than 0.

Therefore, the no-load power acquired in the uncharged state may be stored in the first electronic device in advance as the difference threshold. In the normal use process of the first electronic equipment after leaving a factory, the first electronic equipment can acquire the output voltage and the output current of the first wireless charging chip, and output power is obtained through calculation. And comparing the output power of the first wireless charging chip with a power threshold. If the output power of the first wireless charging chip is greater than the power threshold, the first wireless charging chip is in a charging state, and the state of the second electronic device is an adsorption state. Otherwise, if the output power of the first wireless charging chip is not greater than the power threshold, for example, equal to the power threshold, it indicates that the first wireless charging chip is not in a charging state, and at this time, the adsorption state of the second electronic device is a take-off state. That is, in the charged state, the current at the time of charge cut-off is not 0, prx is greater than 0, and as long as the second electronic device is in the charged state, ptx is greater than Ploss throughout the charging process, the determined take-off state in this case is the true take-off state.

In addition, when the experiment is carried out, an external oscilloscope can be used for collecting the minimum voltage value of the output voltage of the first wireless charging chip, and the output voltage of the first wireless charging chip can be used for screening out abnormal experimental data. For example, if the minimum voltage value acquired by the oscilloscope during an experiment is far smaller than the average value of the output voltage, the experimental data acquired by the experiment can be considered as abnormal experimental data, and the abnormal experimental data can be deleted.

Of course, when the first electronic device obtains the output voltage and the output current of the first wireless charging chip, the first electronic device may obtain the output voltage and the output current of the continuous period to calculate the corresponding average voltage and average current. For example, the continuous period may be between 5 ms and 30 ms, so that the waiting time for acquiring the device state is not too long, and more accurate electrical parameters can be acquired as far as possible, so as to reduce the influence of possible signal fluctuation on the accuracy of the acquired device state.

On the basis of the above embodiment, as shown in fig. 6, after determining that the real-time state of the second electronic device is the adsorption state, the first electronic device may further execute step S609 to control the first wireless charging chip to charge the second wireless charging chip in order to ensure the available state of the second electronic device. Therefore, the electric quantity of the second electronic equipment can be ensured to be in a higher electric quantity state all the time, and the use of a user is facilitated.

The equipment state detection method provided by the embodiment of the application can acquire a more real charging state according to the output power of the first wireless charging chip. Based on the above, the actual charging time length of the first electronic device for the second electronic device can also be obtained by monitoring the output power and the power threshold value of the first wireless charging chip. And comparing the actual charging time with the preset maximum charging time of the second electronic equipment to avoid possible battery damage caused by the maximum safe charging time exceeding the effective charging time.

Fig. 8 is a block diagram of a software and hardware structure of a first electronic device according to an embodiment of the present application. The software system of the first electronic device may adopt a layered architecture, where the layered architecture divides the software into a plurality of layers, each layer has a clear role and division, and the layers communicate with each other through software interfaces. In some embodiments, the software is divided into three layers, from top to bottom, an application layer (APPlication), a FrameWorK layer (FrameWorK, FWK), and a hardware abstraction layer (Hardware Abstraction Layer, HAL), respectively.

The application layer (i.e., application layer) may include a series of application packages, such as a setup application, a camera application, a stylus application, and the like. In this embodiment, software for implementing the device state acquiring method may be a setting application, or may be a separate stylus application, and is not limited thereto. This embodiment is exemplified by setting an application.

The application framework layer (i.e., framework layer) provides an application programming interface (Application Programming Interface, API) and programming framework for the application of the application layer. The application framework layer includes a number of predefined functions. The application framework layer may include a window manager, a content provider, a view system, a telephony manager, a resource manager, a notification manager, and the like. The window manager is used for managing window programs. The window manager can acquire the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like. The content provider is used to store and retrieve data and make such data accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phonebooks, etc. The view system includes visual controls, such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, a display interface including a text message notification icon may include a view displaying text and a view displaying a picture. The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like. The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction.
