Automatic shutdown method and device for mobile terminal and mobile terminal

Abstract

The embodiments of the present invention disclose an automatic power-off method for a mobile terminal. The method comprises the following steps: receiving an instantaneous acceleration value of a mobile terminal in the vertical direction, which is detected by a gravity sensor in real time; judging whether the received instantaneous acceleration value is greater than or equal to a preset acceleration threshold value or not; and if the instantaneous acceleration value is greater than or equal to the preset acceleration threshold value, sending a power-off instruction to a hard power-off circuit module so as to cut off a power source of the mobile terminal. The embodiments of the present invention also disclose an automatic power-off device, a mobile terminal and a computer storage medium.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method, device and mobile terminal for automatic shutdown of a mobile terminal. Background technique [0002] With the rapid development of information technology, multimedia products are becoming more and more closely related to people's lives, and multimedia products have become an indispensable part of daily life. With the increase in the application rate of multimedia products, there are more and more emergencies of multimedia products in various environments, and the most common incidents caused by product failure are the most common ones. [0003] At present, traditional multimedia products, such as MP3, MP4, etc. are used for fall protection methods. The existing protection schemes mainly consider the selection of raw materials and the design of engineering mechanical structures to protect them. For example, when a multimedia product is dropped, the outer shell ...

Problems solved by technology

However, these methods have a major disadvantage: if the multimedia product is in the power-on state during the fall, the software and hardware of the multimedia product will always be in the running state, and the software program will affect the I / O port of the ROM / RAM when it is running. access control

When a multimedia product is dropped and subjected to a severe external impact, errors may occur to the input and output control devices and programs being accessed, resulting in damage to hardware chips or software crashes, and even damage to the system after the execution of the Boot solidified boot program is destroyed. The software is not recoverable even after restarting

In addition, after the electronic components are severely dropped and collided during live operation, the electronic components may be directly damaged and cannot continue to work.
