The sensor module 206 may include a touch sensor 206A, an Acceleration (ACC) sensor 206B, a photoplethysmography (PPG) sensor 206C, and the like. Wherein:

the touch sensor 206A may also be referred to as a "touch device". The touch sensor 206A may be provided to the display screen 205. The touch screen composed of the touch sensor 206A and the display screen 205 may also be referred to as a "touch screen".

The ACC sensor 206B may be used to detect the magnitude of acceleration of the electronic device 200 in various directions (typically x, y, and z axes). For example, when the electronic device 200 is stationary, the ACC sensor 206B may detect the magnitude and direction of gravity.

Taking the example of detecting the heart rate of the user, in a particular implementation, the PPG sensor 206C may emit a light signal of a specified wavelength that may impinge on arterial blood vessels under skin tissue and be reflected back to the PPG sensor 206C. When the heart beats, the contraction and expansion of the blood vessel changes the volume of blood in the arterial vessel, and thus affects the absorption or attenuation of the optical signal by the arterial vessel, and thus affects the reflection of the optical signal. The PPG sensor 206C may detect the heart rate of the user based on the change in the reflected light signal. It should be noted that, the PPG sensor 206C may also detect the heart rate of the user by other methods, which is not limited in this application.

Optionally, the electronic device 200 may further include a USB interface, through which the electronic device 200 may establish a wired communication connection with the electronic device 100, and transmit data information with each other through the wired communication connection.

It should be understood that the electronic device 200 shown in fig. 3 is merely one implementation of the embodiments of the present application and is not intended to limit the electronic device 200 in any way. Preferably, the electronic device 200 may be a smart watch, and the electronic device 200 may further include a watchband and a dial. The dial may include a display 205 for displaying images, videos, controls, text information, and the like. The wristband may be used to secure the electronic device 200 to a person's extremities for ease of donning. In practice, the electronic device 200 may include more or fewer components than shown without limitation.

Next, a process of detecting whether a user is in a sleep state according to the embodiment of the present application will be described.

The exemplary illustration is given taking electronic device 200 as a smart watch. In some application scenarios, the electronic device 200 may secure the electronic device 200 on a wrist of a user through a wristband. The electronic device 200 may detect whether the user is in a sleep state through the ACC sensor and the PPG sensor.

Specifically, when the electronic device 200 detects that the acceleration values in the x-axis, y-axis, and z-axis are smaller than the specified threshold A1 by the ACC sensor, and at the same time, the heart rate of the user is smaller than or equal to the specified threshold A2 by the PPG sensor, and is maintained for a certain period of time (for example, 10 minutes), the electronic device 200 may determine that the user is in a sleep state.

However, the above-mentioned process of detecting whether the user is in the sleep state often causes the electronic device 200 to misjudge that the user has entered the sleep state. For example, when the user lies on a sofa for a long time and plays a cell phone and is not active, the body of the user is in a stationary state, and the electronic apparatus 200 may detect that acceleration values in the x-axis, y-axis, and z-axis are less than the specified threshold A1 and the heart rate of the user is less than or equal to the specified threshold A2 for a certain period of time through the ACC sensor, and thus the electronic apparatus 200 determines that the user is in a sleep state. However, in an actual scenario the user has not yet fallen asleep, and is still awake. The misjudgment of the sleep state can cause the problems that the sleep data obtained by the electronic equipment and the real sleep data have larger errors, the accuracy of the sleep data is lower, and the like.

Accordingly, the embodiment of the application provides a sleep state detection method.

In particular, the method may be applied to the communication system 10 described previously.

First, the electronic apparatus 200 may determine that the user is in a suspected sleep state through the ACC sensor. The electronic device 200 may then send a display screen status detection instruction to the electronic device 100. After receiving the display screen state detection instruction, the electronic device 100 may acquire the display screen state of the electronic device 100. The electronic device 100 or the electronic device 200 may determine the device state of the electronic device 100 according to the display screen state of the electronic device 100. Here, the device state of the electronic device 100 can be divided into: a use state and a non-use state. The use state refers to that the user is using the electronic device 100, and the non-use state refers to that the user is not using the electronic device 100.

When the electronic device 100 or the electronic device 200 determines that the device state of the electronic device 100 is in the non-use state according to the display screen state of the electronic device 100, the electronic device 200 may detect sleep data of the user through data information of the PPG sensor. When the electronic device 100 or the electronic device 200 determines that the device state of the electronic device 100 is in the use state according to the display screen state of the electronic device 100, the electronic device 200 does not detect sleep data of the user through data information of the PPG sensor. In some examples, the electronic device 200 may clear acceleration data acquired by the ACC sensor when the device state of the electronic device 100 is in the use state.

As can be seen from the steps of the sleep state detection method described above, the sleep detection method provided in the embodiment of the present application may indirectly determine the behavior of the user (for example, whether to use the electronic device 100) through the display screen state of the electronic device 100, and detect the sleep data of the user by combining the data information acquired by the ACC sensor and the PPG sensor. In this way, the occurrence probability of misjudging the sleep state of the user can be reduced, the accuracy of judging the sleep state of the user can be improved, and meanwhile, the power consumption of the electronic equipment 200 can be reduced, and the accuracy of acquiring the sleep data of the user can be improved.

Next, a specific flow of a sleep state detection method provided in the embodiments of the present application is described.

Referring to fig. 4, fig. 4 is a schematic flow chart schematically illustrating a sleep state detection method according to an embodiment of the present application.

As shown in fig. 4, the specific flow of this embodiment may be as follows:

s401, the electronic device 100 and the electronic device 200 establish wireless communication connection.

Preferably, the wireless communication connection is exemplified by a bluetooth connection in the embodiments of the present application. The electronic device 100 may detect or scan the electronic device 200 by transmitting a signal through the bluetooth module, establish a wireless communication connection with the electronic device 200, and transmit data information to each other. Wherein the bluetooth module may provide a solution comprising one or more bluetooth communications of BR/EDR or BLE.

In some examples, the electronic device 100 may also detect or scan the electronic device 200 by transmitting signals over the WLAN module, establishing a wireless communication connection with the electronic device 200 and transmitting data information to each other. The WLAN module may provide a solution including one or more WLAN communications among Wi-Fi direct, wi-Fi LAN, or Wi-Fi softAP, among others.

In other examples, the electronic device 100 may also establish a wireless communication connection with the electronic device 200 through frequency modulation (frequency modul ation, FM), near field communication (near field communication, NFC) or Infrared (IR), and transmit data information with each other based on the wireless communication connection. The present application is not limited in this regard. The present application is not limited in this regard.

S402. the electronic device 200 determines, through the ACC sensor, whether the user is in a suspected sleep state.

Specifically, the electronic device 200 may detect acceleration values in the x-axis, the y-axis, and the z-axis in real time through the ACC sensor. The electronic device 200 may store acceleration values for the three axes described above for a specified period of time C1 (which may also be referred to as a first period of time, e.g., approximately 30 minutes). When the electronic apparatus 200 detects that the acceleration values of the three axes are smaller than the specified threshold A1 (may also be referred to as a first threshold, for example, 1.1m/s 2) in the specified period C2 (may also be referred to as a second period, for example, in approximately 10 minutes), and that the time period in which the acceleration values of the three axes are larger than the specified threshold A1 is smaller than the specified time period B3 (for example, 3 minutes) in the specified period C3 (for example, in approximately 15 minutes), the electronic apparatus 200 may determine that the user is in a suspected sleep state. The electronic device 200 may perform the following steps. Otherwise, the electronic device 200 determines that the user is not in the suspected sleep state, and the electronic device 200 may continue to execute the flow of this step.

In one possible implementation, the electronic device 200 may store acceleration values for the three axes over a specified period of time C1 (e.g., approximately 30 minutes). When the electronic device 200 detects that the acceleration values of the above three axes are less than the specified threshold A1 (e.g., 1.1m/s 2) in the specified period C2 (e.g., in approximately 10 minutes), the electronic device 200 may determine that the user is in a suspected sleep state.

S403, when the electronic device 200 determines that the user is in a suspected sleep state, the electronic device 200 sends a display screen state detection instruction to a first application in the electronic device 100.

Specifically, the electronic device 200 may send a display screen state detection instruction to the first application in the electronic device 100 based on the wireless communication connection established in the foregoing S401. Preferably, the electronic device 200 may send the display status detection instruction to the first application in the electronic device 100 based on the bluetooth connection.

S404, after a first application in the electronic device 100 receives the display screen state detection instruction, the electronic device 100 acquires the display screen state of the electronic device 100 through the first application at intervals of a designated duration B1 (for example, at intervals of 3 seconds).

Specifically, the specified function/specified service in the display status detection module in the electronic device 100 may detect the status of the display on the electronic device 100 every specified duration B1 (e.g., every 3 seconds). Then, the first application in the electronic device 100 may acquire the display screen state of the electronic device 100 detected by the above-described designation function/designation service every designated period B1 (may also be referred to as a first period, for example, every 3 seconds). The display status detection module may be located in an application framework layer of the electronic device 100.

For example, the electronic device 100 may detect that the display screen is in a bright screen state or in an off screen state based on an iscorenen ("isscreen") function in a powermanager service. The bright screen state may refer to a state in which all areas of the display screen on the electronic device 100 are lit up for display; the off-screen state may refer to a state in which the display screen of the electronic device 100 is dormant to be a black screen, the display screen does not display interface elements, but other devices and programs normally operate. The electronic device 100 may detect that the display is in a locked state or in an unlocked state based on a system broadcast event. The screen lock state may refer to a state in which a part of functions of the electronic device 100 are locked, that is, the electronic device 100 does not provide a part of functions. The functionality provided by the electronic device 100 in the locked state requires less data security, for example: answering calls, hanging up calls, adjusting the volume of music, starting camera applications, turning on/off flight modes, etc. In the unlocked state, the electronic device 100 can provide not only the above-mentioned functions with low data security requirements, but also functions with high data security requirements, for example: a portion of the application (e.g., a WeChat application) is launched, and the functionality provided by the application (e.g., displaying a WeChat payment interface). That is, in the unlocked state, the electronic device 100 may provide functions that all of the electronic device 100 may perform.

It is to be understood that the above-described exemplary illustrations are for purposes of explanation only and are not to be construed as limiting the present application in any way. The electronic device 100 may also obtain the display status of the electronic device 100 in other ways.

Otherwise, the electronic device 100 determines that the device state of the electronic device 100 is in a non-use state.

Wherein the display screen being in the first state may refer to: the display screen is in a bright screen state and in an unlocked state, or the display screen is in a bright screen state and whether the display screen is in a locked screen state is not limited. Preferably, in the embodiment of the present application, taking an example that the display screen is in the first state, that the display screen is in the bright screen state and that the display screen is in the unlock state as an example, a flow of implementing the present embodiment is described.

For example, when the first application of the electronic device 100 acquires the display status of the electronic device 100 every 3 seconds, the first application of the electronic device 100 may record the display status. When the first application of the electronic device 100 determines that the display screen on the electronic device 100 is in the bright screen state and the time of the unlock state is greater than 51 seconds within 1 minute based on the recorded display screen state, the electronic device 100 may determine that the device state of the electronic device 100 is in the use state.

When the electronic device 100 determines, based on the display screen state, through the first application that the time that the display screen is in the first state on the electronic device 100 is less than or equal to the specified duration B2 (e.g., 51 seconds) within the specified period of time C4 (e.g., within 1 minute), the electronic device 100 determines that the device state of the electronic device 100 is in the non-use state.

For example, when the first application of the electronic device 100 acquires the display status of the electronic device 100 every 3 seconds, the first application of the electronic device 100 may record the display status. When the first application of the electronic device 100 determines that the display screen on the electronic device 100 is in the bright screen state and the time of the unlock state is less than or equal to 51 seconds within 1 minute based on the recorded display screen state, the electronic device 100 determines that the device state of the electronic device 100 is in the non-use state.

Specifically, when the electronic device 200 receives the state information of the electronic device 100 to indicate that the device state of the electronic device 100 is in the non-use state, the electronic device 200 may acquire sleep data of the user through the heart rate and/or blood oxygen of the user detected by the PPG sensor.

In some examples, when the wireless communication connection established between the electronic device 100 and the electronic device 200 is unstable, or the wireless communication connection established between the electronic device 100 and the electronic device 200 has been disconnected, the electronic device 200 does not receive the status information of the electronic device 100 within a specified period C5 (for example, 1.5 minutes, 2 minutes, etc.) after sending the display status detection instruction to the electronic device 100, at this time, the electronic device 200 may acquire sleep data of the user through the heart rate and/or blood oxygen of the user detected by the PPG sensor.

In some examples, the electronic device 200 may clear acceleration data acquired by the ACC sensor when the device state of the electronic device 100 is in the use state.
