Embodiment Construction

[0022] The core idea of ​​the present invention is: the present invention monitors the working state of the main battery through the power-off trigger installed in the mobile phone. The CPU of the mobile phone saves the data in operation according to the trigger signal to prevent data loss. At the same time, the battery is switched to the backup battery working mode through the power switcher, and the battery is powered by the backup battery to realize the normal shutdown of the mobile phone.

[0023] In order to illustrate the idea and purpose of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] See figure 1 as shown, figure 1 It is a system block diagram of the present invention. The invention provides a smart phone power-off protection system, which is mainly used to solve the problems of mobile phone data loss and system inability to start when the smart phone is p...

Abstract

According to a power-off protection system and method for a smart phone, when the smart phone is powered down, a power-down trigger generates a power-off signal, and a phone CPU (central processing unit) perform processing and analysis after acquiring the power-down signal, stores currently-processed data into a temporary Flash memory, generates a power-off instruction and controls the smart phone to power off normally. Compared with the prior art, when the phone is powered down, the power-off protection system and method for the smart phone can guarantee the determinacy of the system operation state and the integrity of recorded data and ensure to power off the system normally, thereby having good protection effects on the phone. When system power supply is restored, the currently-processed data of the phone can be restored timely, so that the problems of system chaos, phone data loss and incapability of starting the system can be effectively avoided.

Description

technical field [0001] The invention relates to a smart phone, in particular to a smart phone power-off protection system and method to solve the problems of data loss and system inability to start when the smart phone is powered off. Background technique [0002] Smartphones have an independent operating system, and users can install programs provided by third-party service providers such as software and games by themselves. Through such programs, the functions of mobile phones can be continuously expanded, and wireless network access can be realized through mobile communication networks. . [0003] With the rapid development and popularization of smart phones, more and more functions can be realized on smart phones, such as text editing, file read and write operations, software installation, etc. Since smart phones have an open operating system, more There are many applications, so that the functions of the smartphone can be expanded infinitely, but too many installed pro...
