Automatic screen-locking system and method for mobile phone placed in pocket

Abstract

The invention discloses an automatic screen-locking system and a method for a mobile phone placed in a pocket. The automatic screen-locking system and the method comprises the following steps: step A, a microprocessor correspondingly acquires an induction signal of the mobile phone; step B, the microprocessor compares the induction signal with a threshold value correspondingly stored in a storer, acquires a mobile-phone-placed-in-pocket signal, and transmits the mobile-phone-placed-in-pocket signal to a central processing unit (CPU); and step C, the CPU processes the phone-placed-in-pocket signal, transmits the mobile-phone-placed-in-pocket signal to a screen-locking signal, and correspondingly controls a display screen to conduct screen locking through the screen-locking signal. According to the automatic screen-locking system and the method for the mobile phone placed in the pocket, an luminance sensor, an acceleration sensor and a distance sensor conduct signal induction on whether the mobile phone is placed in the pocket, the microprocessor is used for judging and analyzing, mobile-phone-placed-in-pocket information is acquired, then the CPU controls a locking module to lock the screen, and the purpose that the screen of the mobile phone is automatically locked after the mobile phone is placed in the pocket is achieved. The automatic screen-locking system and the method solve problems that after the mobile phone is placed in the pocket, electric quantity of a battery of the mobile phone is wasted and misoperation is easily caused due to the fact that the screen is not locked in time.

Description

technical field [0001] The invention relates to mobile phone screen lock technology, in particular to a system and method for automatically locking the screen when the mobile phone is put into a pocket, which mainly solves the problem of wasting battery power of the mobile phone and easily causing misoperation due to failure to close the screen in time after the mobile phone is put into the pocket question. Background technique [0002] With the rapid development of smart phones, the use of touch screens is becoming more and more popular. While touch technology brings superior mobile phone experience to users, it also puts forward higher requirements for battery power. Usually, in order to reduce the consumption of battery power, when the mobile phone is not in use, it is necessary to turn off the screen of the mobile phone to make it in a standby state. The current method is to directly press the switch button of the mobile phone to turn off the screen or turn off the scre...
