Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative work fall within the protection scope of the present application.

For example, a process, method, system, product or device comprising a series of steps or elements is not limited to the listed steps or elements, but may include unlisted steps or elements.

In order to make those skilled in the art better understand the solution of the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

Next, a wake-up method for a smart wearable device provided by an embodiment of the present application is introduced in detail. FIG. 1 is a flowchart of a method for waking up a smart wearable device provided by an embodiment of the present application, and the method includes:

S101: In the case of acquiring the pulse wake-up signal transmitted by the microcontroller, determine whether a new pulse signal is received within a preset time.

The application processor obtains the pulse wake-up signal transmitted by the microcontroller, indicating that the smart wearable device has a wake-up requirement. In order to reduce the power consumption of the smart wearable device, the microcontroller will further transmit a new pulse signal to the application processor. The new pulse signal is used to characterize the wake-up source for the desired wake-up.

In the embodiment of the present application, an interrupt wake-up line and an SPI (SerialPeripheral Interface, serial peripheral interface) communication bus are set between the application processor and the microcontroller. The interrupt wake-up line can be a single line, and the SPI communication bus needs to be composed of at least 4 lines. Based on the consideration of the signal transmission rate and transmission power consumption, the microcontroller can transmit the pulse wake-up signal and the new pulse wake-up signal to the application processor through the interrupt wake-up line. Pulse signal.

In practical applications, the application processor can obtain the signal transmitted by the microcontroller through the interrupt wake-up line; if the signal is a high-level pulse, it indicates that the signal is a pulse wake-up signal, and at this time, it can be further judged whether it is within the preset time. A new pulse signal is received.

The value of the preset time may be set based on actual requirements, for example, the preset time may be set to 1 millisecond (ms).

After acquiring the pulse wake-up signal transmitted by the microcontroller, if the application processor does not receive a new pulse signal within a preset time, it can wake up all components and tasks of the smart wearable device in a conventional manner.

The application processor receives a new pulse signal within the preset time, indicating that it is not necessary to wake up all components and tasks of the smart wearable device at present, but to wake up some components and tasks corresponding to these components according to the current requirements. S102 may be executed when a new pulse signal is received within a preset time. The tasks corresponding to the components can be implemented based on the application.

S102: Based on the set correspondence between the wake-up source and the pulse distribution, determine the target wake-up source matching the pulse signal.

In the embodiment of the present application, in order to reduce the power consumption of the smart wearable device, different types of pulse signals may be set according to different wake-up requirements. In practical applications, different types of pulse signals can be characterized according to the number of pulses contained in the pulse signal per unit time. That is, the pulse distribution can be the number of pulses contained in the pulse signal per unit time. The unit time can be 1ms.

The number of pulses contained in the pulse signal per unit time is different, and the corresponding wake-up sources are different. Wherein, the wake-up source may include peripheral devices connected to the microcontroller in the smart wearable device. Peripherals can include various types of sensors, such as heart rate modules, accelerometers, and altimeters.

In practical applications, the application processor may pre-record the correspondence between wake-up sources and pulse distribution, and the correspondence may include pulse signal types corresponding to different wake-up sources; wherein different pulse signal types include different numbers of pulses.

When the application processor receives a new pulse signal, it can identify the target pulse number contained in the pulse signal; query the correspondence between the wake-up source and the pulse distribution, and determine the target wake-up source corresponding to the target pulse number.

For example, the pulse signal sent by the microcontroller within 1 ms contains 1 pulse, indicating that the heart rate detection function is turned on, and the corresponding wake-up source is the heart rate module; the pulse signal sent by the microcontroller within 1 ms contains 2 pulses, indicating When the step counting function is turned on, the corresponding wake-up source is the acceleration sensor; the pulse signal sent by the microcontroller within 1 millisecond contains 3 pulses, indicating that the positioning function is turned on, and the corresponding wake-up source is the altimeter.

FIG. 2 is a schematic diagram of a pulse signal provided by an embodiment of the present application. After the microcontroller transmits a pulse wake-up signal to the application processor, it can transmit a new pulse signal. In FIG. 2, three kinds of pulse signals are listed. The form of the pulse signal, from top to bottom, is a pulse signal containing one pulse, a pulse signal containing two pulses, and a pulse signal containing three pulses.

S103: Wake up the components and tasks corresponding to the target wake-up source.

The target wake-up source can be a component that needs to perform wake-up. Considering that in practical applications, various components in the smart wearable device have functional correlations. In addition to the target wake-up source, the component corresponding to the target wake-up source may also include a component that is functionally related to the target wake-up source.

The wake-up source of the screen display type may be that the wake-up source needs to cooperate with the display screen, for example, the information collected by the wake-up source is displayed through the display screen. The wake-up source of data transmission type may be that the wake-up source needs to cooperate with the wireless communication component, for example, the information collected by the wake-up source is transmitted to the APP through the wireless communication component.

Taking the screen display type wake-up source as an example, the application processor can start the wake-up source, the display screen, and the respective application programs corresponding to the wake-up source and the display screen.

Wherein, the screen display type wake-up source may include a heart rate module and/or an acceleration sensor.

Taking a wake-up source of data transmission type as an example, the application processor can start the wake-up source, the wireless communication part, and the respective application programs corresponding to the wake-up source and the wireless communication part.

Wherein, the wake-up source of the data transmission type may include an altimeter.
