File format and data power failure restoration method and system based on intelligent terminal

Abstract

The invention provides a file format and data power failure restoration method and system based on an intelligent terminal. The method specifically comprises the following steps: detecting the power failure event of a system at the intelligent terminal; checking a data backup area, judging whether the file format in the system is corrupted, if the file format is corrupted, performing the corresponding file format restoration operation according to a pre-stored file format attribute and to-be-restored file configuration information, and then saving; further judging whether the file data of the system is corrupted, if the file data is corrupted, performing the corresponding data restoration operation according to a pre-stored file log, and then saving. Through the adoption of the method provided by the invention, the cleaning operation of the original system restoration method is avoided, the data loss when an accident occurs is reduced, the data restoration efficiency is improved, and the convenience is provided for a user.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a file format and data power-off repair method and system based on an intelligent terminal. Background technique [0002] For monitoring and driving recording equipment, the recorded data before the accident is very important. In practice, after the power failure occurs, the record files at that time are likely to be damaged. In this way, the accident scene cannot be accurately restored, which will cause troubles to the analysis and handling of the accident. The existing technology mainly adopts: (1) adding a backup battery, but for some equipment with harsh working conditions, the battery has a high risk of working under such conditions and is not applicable; (2) the file system and The disk drive will generate abnormality when the system is powered off, and the existing repair operation after power-on will often lead to the overwriting of abnormal data, r...
