At present, various terminals, such as smart phones and tablet computers, have become indispensable communication, entertainment and life tools in people's lives. Auxiliary products of terminals, such as protective cases, are also widely used in terminals for their anti-drop, anti-scratch, and aesthetic functions. At present, in addition to protecting the terminal, the protective shell of the terminal also has other auxiliary functions, such as controlling the terminal through the protective shell. For example, the screen lock function of the protective case: when the user closes the protective case of the terminal, the terminal locks the screen; when the user opens the holster, the terminal wakes up the screen, thereby saving power consumption of the terminal and facilitating user operation.

The control principle of the existing protective shell on the terminal is mainly to identify the state of the protective shell by sensing the magnetic field generated by the magnet of the flip cover of the holster through the Hall sensor built in the terminal.

The terminal control method provided by the embodiment of the present invention is discussed in detail below.

Please refer to FIG. 7. FIG. 7 is a terminal control method provided by an embodiment of the present invention.

Step S100: The terminal detects the current state of the protective shell.

Specifically, the state of the protective shell includes an open state and a closed state. When the terminal detects that the current state of the protective shell is an open state, the terminal may perform steps S200 and S300; when the terminal detects that the current state of the protective shell is a closed state, the terminal Steps S400 and S500 may be performed.

Please refer to FIG. 8. FIG. 8 is another terminal control method provided by an embodiment of the present invention. An implementation manner of electronically detecting the current state of the protective case may include steps S101, S102, S103, S104, S105, and the like.

Step S101: The terminal acquires the light intensity value through the light sensor.

It can be understood that the light sensor can obtain the light energy in the environment and convert the light energy into electrical signals to obtain the light intensity value.

Step S102: The terminal determines whether the light intensity value is greater than a first light intensity threshold.

Specifically, in the case of sufficient light in the environment, the light intensity value of the terminal detected by the optical sensor when the protective shells are respectively in the open state is much larger than that detected by the optical sensor when the protective shells are in the closed state respectively. strong value. However, in the case of insufficient light in the environment, the light intensity values detected by the light sensor when the protective case of the terminal is in an open state and a closed state, respectively, are relatively small. The first light intensity threshold is not less than the light intensity value obtained by the terminal through the light sensor when the ambient light is sufficient and the protective case is in a closed state.

When the light intensity value is greater than the first light intensity threshold, it means that the protective case is in an open state and the light in the current environment is sufficient, and the terminal can perform step S103; when the light intensity value is not greater than the first light intensity threshold, it means that the protective case is in In a closed state, or indicating that the protective case is in an open state and there is no light source or insufficient light in the current environment, the terminal may perform step S104.

Step S103: The terminal detects whether the change of the acquired light intensity value from time T1 to time T0 is greater than the second light intensity threshold.

Wherein, time T0 is the current time, and T1 is the time of the first duration before the current time. The first duration may be 0.5s, 1s, or 2s, or the like.

When there is sufficient light in the environment, when the protective shell changes from the open state to the closed state, the light intensity value detected by the terminal within the state transition time of the protective shell will send strong fluctuations, that is to say, the obtained light intensity value during this time period The change in the light intensity value is greater than the second light intensity threshold. Wherein, the second light intensity threshold may be the minimum light intensity value obtained by the terminal when there is sufficient light in the environment and the protective case is in an open state and the maximum light intensity value obtained by the terminal when there is sufficient light in the environment and the protective case is in a closed state Difference.

If it is detected that the change of the light intensity value is greater than the second light intensity threshold, it means that there is an obstruction blocking the light sensor of the terminal, or the environment has changed from sufficient light to insufficient light. The obstruction may be the user's hand, or it may be The flip cover of the protective case, at this time, the terminal can perform step 200; if it is detected that the change of the light intensity value is not greater than the second light intensity threshold, and the state of the protective case has not changed greatly, the terminal can perform step S101 to pass the light again The sensor gets the light intensity value.

Step S104: The terminal detects whether a user operation is received from time T0 to time T2.

Specifically, when the terminal receives a user operation, the protective shell is in an open state; when the terminal does not receive a user operation, the terminal may be in an open state or a closed state. The terminal may monitor the user operation in real time, and when the terminal detects that the user operation is not received from time T0 to time T2, the terminal may be triggered to perform step S200.

Wherein, the time T0 is the current time, and T2 is the time of the second duration after the current time, and the second duration may be 5s, 10s, 16s, or the like. The second duration may be smaller than the no-operation response duration for entering automatic sleep mode set by the terminal. The user operation may be an operation input by the user through a keyboard, a mouse, a key, a touch screen, a remote control, etc., for example, a click operation on a target on the touch screen of the terminal.

When the terminal detects that a user operation is received from time T0 to time T2, it is considered that the user is using the terminal and the protective shell of the terminal is in an open state. At this time, the terminal can perform step S101 or continue to perform step S104; If no user operation is received from time T0 to time T2, it is considered that the user stops operating the terminal, and the user may perform a closing operation on the protective shell. At this time, the terminal can perform step S200 to further verify whether the protective shell is closed.

It can be understood that the terminal can also identify or assist in identifying the current state of the protective shell through other devices or methods. For example, the terminal may include a pressure sensor. When the protective case of the terminal is in a closed state, the pressure sensor may detect the pressure information generated by the flip cover of the protective case covering the pressure sensor. When the terminal detects the pressure information through the pressure sensor When it is greater than the preset pressure threshold, it is recognized that the protective shell is in a closed state; otherwise, the protective shell is in an open state.

For another example, the terminal may include a distance detection device disposed on the front of the terminal, and the distance of an object directly above the terminal may be detected by the distance detection device. When the protective case is in the closed state, the flip cover is close to the distance detection device, and the distance value detected by the terminal is far smaller than the distance value detected by the distance detection device when the protective case is in the open state. When the distance value detected by the distance detection device is less than a preset distance threshold, such as 1 cm, it is recognized that the protective case is in a closed state; otherwise, the protective case is in an open state.

For another example, the terminal can also identify the current state of the protective case through the Hall sensor.

Step S200: The terminal performs on-off control of the light-emitting device according to the first rule, and detects whether the change rule of the first light intensity value received by the light sensor is consistent with the first rule.

Specifically, referring to the light guide principle of the light guide strip in the protective shell shown in FIG. 2 or FIG. 3 , it can be seen that when the protective shell is in the open state, almost all the light emitted by the light-emitting device diffuses into the surrounding environment, and can be absorbed by the light. The light captured by the sensor is very small, which is not enough to show the information carried by the regular opening and closing of the light-emitting device; only when the protective case is in the closed state, the light sensor will detect the regular change of the first light intensity value or the first light intensity value. A change rule of the first light intensity value that is consistent with a rule.

The first rule may be a rule formed by the terminal by controlling the turn-on time and turn-off time of the light-emitting device. The first rule may have periodic switch control, such as turning on the indicator light, turning off the indicator light after 1 s, turning on the indicator light after 2 s, and performing on-off control of the light-emitting device as a cycle.

For example, please refer to FIG. 9. FIG. 9 is a schematic diagram of the detection principle of the change rule of the first light intensity value provided by the embodiment of the present invention. , wherein a high level indicates that the light-emitting device is in an on state, and a low level indicates that the light-emitting device is in an off state. It can be understood that the square wave has a certain frequency, duty cycle, and the like.

When the protective case is in a closed state, the image formed by the first light intensity value received by the light sensor is shown as waveform 902 . In the first aspect, the terminal can analyze whether the waveform 902 is a regularly changing waveform, such as whether it contains a specific frequency. When the waveform 902 is a regularly changing waveform, then the first light intensity value received by the light sensor changes the law. Consistent with the first rule. In the second aspect, the terminal can analyze the frequency of the waveform 902. When the frequency of the waveform 902 is equal to the frequency of the square wave 901 or the difference is smaller than a preset threshold (such as 1 Hz, etc.), the first light intensity value received by the light sensor The change rule of is consistent with the first rule. In the third aspect, the terminal can calculate the duty cycle of the waveform 902 and the duty cycle of the square wave 901. When the difference between the duty cycle of the waveform 902 and the duty cycle of the square wave 901 is less than a preset threshold, such as 0.05, the light The variation rule of the first light intensity value received by the sensor is consistent with the first rule. In the fourth aspect, the terminal can perform filtering processing on the waveform 902, such as performing a comparison operation to form a waveform 903, by comparing whether the frequencies of the square wave 901 and the waveform 903 are equal, or the difference between the duty cycles of the square wave 901 and the waveform 903. Whether the change rule of the first light intensity value received by the sensor conforms to the first rule is determined whether it is less than the preset threshold, and reference may be made to the relevant descriptions in the second aspect and the third aspect above.

It can be understood that when the terminal is placed in the user's pocket or in a moving vehicle, due to the regular movement of the user or the regular bumping of the vehicle, the protective case may be opened and closed at a small angle continuously. At this time, the terminal can also detect the first A regular change of the light intensity value, at this time, it can be further judged whether the frequency or duty cycle of the first light intensity value conforms to the first law, if so, the first light intensity value received by the light sensor is The changing law is consistent with the first law.

It can be understood that when the protective case is in an open state, in step S200, the terminal may perform one-cycle on-off control on the light-emitting device, or can perform multiple-cycle on-off control.

When the change rule of the first light intensity value received by the light sensor is consistent with the first rule, the protective case enters the closed state, and the terminal may perform step S300; otherwise, the protective case is in the open state, and the terminal may perform step S100 , S101 or S104, the terminal may also control the terminal to enter the sleep state when the monitored inactivity duration of the terminal exceeds the inactivity response duration set by the terminal to enter automatic sleep.

Step S300: The terminal performs the first operation.

Specifically, when it is detected that the change rule of the first light intensity value received by the light sensor is consistent with the first rule, the terminal detects the closing operation of the protective case, and the terminal can perform the first operation. The first operation may be a sleep operation or a screen-off operation, so as to reduce the power consumption of the terminal.

Step S400: The terminal controls the on-off of the light-emitting device according to the second rule, and detects whether the change rule of the second light intensity value received by the light sensor is consistent with the second rule.

Specifically, when the terminal recognizes that the protective shell is in a closed state, the terminal can perform on-off control on the light-emitting device according to the second law, wherein, for the description of the second law and the detection principle of the change law of the second light intensity value, please refer to The description about the detection principle of the first law and the change law of the first light intensity value in step S200 will not be repeated in this application. The second law may be the same as the first law or different from the first law, that is, the frequency, duty cycle, etc. included in the second law may be the same or different from those included in the first law.

It can be understood that the terminal continuously controls the switching of the light-emitting device according to the second rule until the terminal detects that the change rule of the second light intensity value does not conform to the second rule. At this time, the terminal may execute step S500.

Step 500: The terminal performs the second operation.

Specifically, when it is detected that the change rule of the second light intensity value received by the light sensor does not conform to the second rule, the terminal detects the opening operation of the protective case, and the terminal can perform the second operation. The second operation may be a wake-up system or a screen wake-up operation.

Step S600: The terminal turns off the light-emitting device.

It can be understood that while or after the terminal performs the second operation, the terminal can turn off the light-emitting device and perform step S101 to prevent the light emitted by the light-emitting device from affecting the identification of the state of the protective case.

In the embodiment of the present application, when the protective case is in an open state, the terminal switches on and off the light-emitting device according to the first rule, and when it is detected that the change rule of the first light intensity value received by the light sensor is consistent with the first rule When it matches, the terminal performs the first operation; when the protective case is in a closed state, the terminal switches on and off the light-emitting device according to the second law, and detects that the change law of the second light intensity value received by the light sensor is consistent with the first operation. When the second rule is not met, the terminal performs the second operation, thereby realizing the control of the terminal by the protective shell.

Moreover, by controlling the light-emitting device to send the optical signal in a certain regularity, the terminal can avoid confusion with the optical signal in the environment received by the optical sensor, and improve the accuracy of the terminal's identification of the state of the protective shell.

The light captured by the sensor is very small, which is not enough to show the information carried by the regular opening and closing of the light-emitting device; only when the protective case is in the closed state, the light sensor will detect the regular change of the first light intensity value or the first light intensity value. A change rule of the first light intensity value that is consistent with a rule.

When the change law of the light intensity value currently received by the light sensor does not conform to the first law, the protective case is currently in an open state; when the change law of the light intensity value currently received by the light sensor conforms to the first law, then the protective case Currently open.

When it is detected that the change law of the light intensity value received by the light sensor changes from not conforming to the first law to conforming to the first law, it means that the protective case has changed from the open state to the closed state, that is, the closing operation for the protective case is detected. At this time, the terminal can perform the first operation. The first operation may be a sleep operation to reduce power consumption of the terminal.

For example, when the terminal switches on and off the light-emitting device at the first frequency, the terminal may perform the first operation when the terminal detects that the frequency of the light intensity value received by the light sensor changes from the non-first frequency to the first frequency.

Step S1030: When detecting that the change rule of the light intensity value received by the light sensor changes from conforming to the first rule to not conforming to the first rule, the terminal performs the second operation.

The second operation may be to wake up the system.

For example, when the terminal switches on and off the light-emitting device at the first frequency, when the terminal detects that the frequency of the light intensity value received by the light sensor changes from the first frequency to a non-first frequency, the terminal can perform the second operation.

In the embodiment of the present application, the terminal performs on-off control on the light-emitting device according to the first rule, and when it is detected that the change rule of the light intensity value received by the light sensor changes from not conforming to the first rule to conforming to the first rule, the terminal executes the first rule.
