Specifically, referring to fig. 1, an embodiment of the present application provides a method for detecting screen use time, where the method for detecting screen use time is used in a mobile terminal, and includes the following steps.
And step S11, when the mobile terminal is in a bright screen state, acquiring the distance L between the mobile terminal and a user at preset time intervals.
In the embodiment of the present application, the preset time may preferably be 30s, but is not limited thereto. If the time setting is too short, the distance measurement is frequent, and the electricity consumption is easy; if the setting time is too long, the distance between the two devices may change during the setting time, and the distance measurement is not accurate.
See fig. 2. Step S11 specifically includes the following steps.
And step S111, sending out ultrasonic waves by the mobile terminal every preset time and receiving the sent ultrasonic waves.
In step S112, the time interval between the transmission and reception of the ultrasonic wave is acquired.
And step S113, acquiring the distance L between the mobile terminal and the user according to the time interval and the propagation speed of the ultrasonic wave in the air.
In the embodiment of the present application, the distance L is obtained by an echo sounding method in ultrasonic ranging. Specifically, an ultrasonic transmitter (such as a receiver) of the mobile terminal transmits ultrasonic waves to a certain direction, a counter (arranged in the mobile terminal) starts timing at the same time of transmitting time, the ultrasonic waves are transmitted in the air and immediately reflected back after encountering a barrier (the face of a user) in the process of being blocked, and an ultrasonic receiver (such as a microphone) immediately stops timing after receiving the reflected ultrasonic waves. The propagation speed of the ultrasonic wave in the air is 340m/s, and the distance L of the emitting point from the obstacle (the face of the user) can be calculated according to the time recorded by the timer.
And step S12, judging whether the distance L meets a preset condition, wherein the preset condition is that L is more than or equal to a and less than or equal to b, and both a and b are positive real numbers. If yes, go to step S13. If not, step S14 is executed.
In the embodiment of the present application, in general, when a user uses a mobile terminal, the user is 8cm to 60cm away from the mobile terminal, so a may be preferably 8cm, and b may be preferably 60cm, but the value ranges of a and b are not limited thereto. If the setting a is too small, the screen is placed in a pocket of a user to be bright, the service time of the screen is also calculated, and if the setting b is too large, the screen is bright when the mobile terminal is not used, the service time of the screen is also calculated, so that the service time of the screen is inaccurate.
And step S13, when the distance L is judged to meet the preset condition, executing a timing function to acquire the screen service time.
In the embodiment of the present application, when the distance L satisfies the preset condition, it indicates that the user is using the mobile terminal, so that a timing function (a counter starts counting) is performed to obtain the screen usage time.
And step S14, when the distance L is judged not to meet the preset condition, the timing function is suspended.
In the embodiment of the present application, when the distance L does not satisfy the preset condition, it indicates that the user does not use the mobile terminal at this time, so that the timing function (the counter suspends counting) is suspended to avoid increasing the time that the user uses the screen.
Step S15, it is determined again whether the distance L satisfies the preset condition. If yes, go to step S16. If not, step S14 is executed.
And step S16, recovering the timing function until the distance L meets the preset condition again.
In the embodiment of the present application, when the user satisfies the preset condition again, it indicates that the user restarts using the mobile terminal at this time, so the counting function is resumed (the counter resumes counting on the basis of the previous time) to obtain the real screen usage time of the user.
In step S17, the timing function is reset every preset period.
In the embodiment of the present application, the preset period generally includes one day, and the timer function is reset to record the screen usage time of the user every day.

In the embodiment of the present application, the preset time may preferably be 30s, but is not limited thereto. If the time setting is too short, the distance measurement is frequent, and the electricity consumption is easy; if the setting time is too long, the distance between the two devices may change during the setting time, and the distance measurement is not accurate.
See fig. 4. The distance acquisition module 301 specifically includes an ultrasonic unit 401, a time acquisition unit 402, and a distance acquisition unit 403.
The ultrasonic unit 401 is configured to send an ultrasonic wave and receive the ultrasonic wave sent back at preset intervals.
The time acquisition unit 402 is used to acquire the time interval between the emission and reception of the ultrasonic waves.
The distance acquiring unit 403 is configured to acquire the distance L between the mobile terminal and the user according to the time interval and the propagation speed of the ultrasonic wave in the air.
In the embodiment of the present application, the distance L is obtained by an echo sounding method in ultrasonic ranging. Specifically, an ultrasonic transmitter (such as a receiver) of the mobile terminal transmits ultrasonic waves to a certain direction, a counter (arranged in the mobile terminal) starts timing at the same time of transmitting time, the ultrasonic waves are transmitted in the air and immediately reflected back after encountering a barrier (the face of a user) in the process of being blocked, and an ultrasonic receiver (such as a microphone) immediately stops timing after receiving the reflected ultrasonic waves. The propagation speed of the ultrasonic wave in the air is 340m/s, and according to the time recorded by the timer, the distance L of the emitting point from the surface of the obstacle (user) can be calculated.
The determining module 302 is configured to determine whether the distance L satisfies a preset condition, where a is greater than or equal to L and less than or equal to b, and a and b are both positive real numbers.
In the embodiment of the present application, in general, when a user uses a mobile terminal, the user is 8cm to 60cm away from the mobile terminal, so a may be preferably 8cm, and b may be preferably 60cm, but the value ranges of a and b are not limited thereto. If a is set to be too small, the screen is placed in a pocket of a user to be bright, the service time of the screen is also calculated, and if b is set to be too large, the screen is bright when the mobile terminal is not used, the service time of the screen is also calculated, so that the service time of the screen is inaccurate.
The execution module 303 is configured to execute a timing function to obtain the screen use time when it is determined that the distance L satisfies the preset condition.
In the embodiment of the present application, when the distance L satisfies the preset condition, it indicates that the user is using the mobile terminal, so that a timing function (a counter starts counting) is performed to obtain the screen usage time.
The suspending module 304 is configured to suspend the timing function when it is determined that the distance L does not satisfy the preset condition.
In the embodiment of the present application, when the distance L does not satisfy the preset condition, it indicates that the user does not use the mobile terminal at this time, so that the timing function (the counter suspends counting) is suspended to avoid increasing the time that the user uses the screen.
The recovering module 305 is configured to recover the timing function until the distance L satisfies the preset condition again.
In the embodiment of the present application, when the user satisfies the preset condition again, it indicates that the user restarts using the mobile terminal at this time, so the counting function is resumed (the counter resumes counting on the basis of the previous time) to obtain the real screen usage time of the user.
The reset module 306 is configured to reset the timing function every preset period.
In the embodiment of the present application, the preset period generally includes one day, and the timer function is reset to record the screen usage time of the user every day.
