Problems solved by technology

[0003] 1: The file system will be repaired at the next startup, and some data will be lost
[0004] 2: The file system is abnormal, the system will fail to start, and it needs to be re-flashed
However, there is currently no related technology that proposes a data protection scheme for cloud terminals when they are abnormally powered off

Embodiment Construction

[0031] figure 1 Shown is a schematic structural diagram of an existing power supply circuit, based on figure 1 In the structure shown, when the terminal is abnormally powered off, the power supply chip will be directly powered off, so that the file system cannot be synchronized in real time, causing data loss or abnormality. In order to solve the above problems,

[0032] In the embodiment of the present invention, the data protection in the case of abnormal power failure is realized through the circuit transformation of the power supply part on the hardware and the cooperation on the software. The circuit transformation of the power supply part is mainly to interrupt the CPU during abnormal power failure, and to use a large capacitor to delay power failure.

[0033] figure 2 It is a schematic flow chart of a data protection method according to an embodiment of the present invention, such as figure 1 As shown, the method includes:

Abstract

Embodiments of the invention disclose a data protection method and apparatus as well as a power supply module. The method comprises the steps that when a system abnormally loses power, the power supply module of a terminal device starts delayed power supply; a central processing unit (CPU) module of the terminal device sends a stop signal to all processes in the system and synchronizes system files; and the CPU module of the terminal device turns off the system. After the system abnormally loses the power, the power supply can be delayed for a period of time to synchronize the file system, so that according to the technical scheme provided by the embodiments of the invention, the data protection in a scene of abnormal power losing can be realized and the data security and the system stability are improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of data protection, in particular to a data protection method, device and power supply module. Background technique [0002] Most of the ARM cloud terminals in the current industry run the Linux operating system. When using the Linux operating system, the file system generally uses Ext3, Ext4, UBIFS, Yaffs, etc. When using these file systems, if a sudden power failure occurs, the following two situations will generally occur: [0003] 1: The file system will be repaired at the next boot, and some data will be lost. [0004] 2: The file system is abnormal, the system will fail to start, and it needs to be re-flashed. [0005] It can be seen that when the cloud terminal is abnormally powered off, because the file system is generally not the reason for real-time synchronization, it is easy to cause data loss or abnormality. [0006] Since cloud terminals are basically powered by AC sockets a...
