System application software backup and restoration method and device

Abstract

The present invention relates to a method and device for restoring a backup of system application software. The method comprises: (a) after an operating system is started, automatically starting a backup detecting and guiding program; (b) performing, by the backup detecting and guiding program, the following steps: performing digital fingerprint checking and testing on a file contained in target application software stored in a normal zone of a memory, if the step of digital fingerprint checking and testing fails, copying the file contained in the target application software stored in a backup zone of the memory to a restoration zone of the memory, and restarting the operating system after the copying is completed; (c) after the operating system is restarted, automatically starting a restoration detecting and guiding program; (d) after the restoration detecting and guiding program is started, performing, by the restoration detecting and guiding program, the following steps: checking whether application software which needs to be restored exists in the restoration zone, if exists, performing an restoring operation on the target application software, and starting a target application program after the restoring operation is completed. Therefore, the method and device according to the present invention can realize the self-restoration of the system application software.

Description

technical field [0001] The invention relates to the technical field of system application software management, in particular to a method for backing up and restoring system application software and a device for backing up and restoring system application software. Background technique [0002] The development of the Internet and the continuous innovation of display screen control technology have promoted the rapid growth of LED display screens in offline display, and the LED display screen control system based on embedded systems has emerged spontaneously. [0003] like figure 1 As shown, the basic components of the embedded LED display control system include: media interface, cascade output port, microprocessor module, media storage module, data processing module and display data output interface. Wherein, the media interface is, for example, a network port, a USB interface and / or an SD card interface; the cascade output port is, for example, a network port, which is suita...

Problems solved by technology

[0005] However, due to the high integration of the embedded microprocessor itself, when there is instability (such as unstable storage modules, unstable running timing), the application software running in it will lose and damage files, making the software unable to run normally.

Due to the "simple and small" characteristics of the embedded system, when there is a problem with the software operation, it cannot be self-recovered, and it can only be returned to the factory for repair, which consumes high maintenance costs and a long cycle; control, the LED display will appear a long-term black screen or display failure, resulting in a series of joint accidents
