- the distance sensor notifies the mobile terminal to process the program, and moves.
- the terminal handler stops timing.
- the fifth step is to record the length of time the user blocks the distance sensor for a duration.
- the length of time is compared with the preset duration (ie, the fixed length of time D). If it is greater than D, the seventh step is performed, otherwise the eighth step is performed.
- Step 7 If the length of time is greater than D, the mobile terminal processing program recognizes that the user inputs a long signal "one", that is, generates an unlock signal for indicating that the time length is greater than D.
- the eighth step if the length of time is less than or equal to D, the mobile terminal processing program recognizes that the user inputs a short signal "-", that is, generates an unlock signal for indicating that the time length is less than or equal to D.
- the unlocking signal is combined with the previously generated unlocking signal to form an unlocking signal sequence, that is, the generated unlocking signal is added to the unlocking signal sequence, and the long signal "one" and the short signal "-” are formed.
- a new unlock signal sequence composed.
- the mobile terminal processing program recognizes the signal type of each time the user operates by the user's repeated occlusion and removal of the distance sensor, thereby forming an unlock signal sequence of the long and short signals.

If the unlock signal sequence matches the preset signal sequence, perform the eleventh step, otherwise perform the first step. In the eleventh step, the screen of the mobile terminal is unlocked, otherwise it remains locked.
- the mobile terminal displays the signal type on the display screen of the mobile terminal every time the unlock signal of the user operation is recognized. For example, when the user inputs a long signal, the mobile terminal software displays a long bar graphic on the screen. When the user inputs a short signal, the mobile terminal software displays a dot pattern on the screen. In order to handle the user input error, a graphic button can be placed on the touch screen, and the user can clear the previous input when the button is clicked. When the unlocking signal sequence input by the user is inconsistent with the preset signal sequence, the mobile terminal prompts the user to input an error.
- the mobile terminal stops the unlocking function when the user inputs the unlocking signal sequence error multiple times in succession. And wait for a certain period of time before allowing the user to unlock. Further, if the signal input is not detected within the set time length after the distance sensor is started, that is, the distance between the object and the screen of the mobile terminal is not detected, the mobile terminal turns off the unlocking function, exits the unlocking state, and waits for the user to re-trigger Unlocked status.
- the mobile terminal determines that the screen unlocking timeout, the mobile terminal exits the unlocking state, and waits for the user to re-trigger the unlocking.
- This embodiment is a preferred embodiment. After the mobile terminal lights up the screen, the user can check whether the input is correct through the screen, thereby improving the correct rate of the input.
- the distance sensor of the mobile terminal is always in the working state. During the time when the mobile terminal is in the locked state and the screen is off (ie, the black screen), the screen unlocking may be performed by repeating the third step to the eleventh step, that is, omitting The second step shown in Figure 3.
- the present invention has the following technical effects:
- the present invention realizes encryption and unlocking of a mobile terminal, and has practicality and confidentiality
- the above technical solution provided by the present invention can be applied to an unlocking process of a mobile terminal, and during a period in which the mobile terminal is in a locked state, determining a length of time that the object approaches the mobile terminal screen and remains within a predetermined distance range; The length, the corresponding unlocking signal is generated; the technical solution for unlocking the mobile terminal by using the unlocking signal solves the problem that the physical button or the touch screen of the mobile terminal is seriously worn out in the related art, and improves the confidentiality of the unlocking of the mobile terminal and Practicality.
