A method and system for storing video screenshots that are easy to retrieve

Abstract

The invention discloses an easy-to-retrieve video screenshot storing method and system. The easy-to-retrieve video screenshot storing method comprises the steps: a screenshot storage server receives screenshot data sent by a client and analyzes the attribute of the screenshot data; the screenshot storage server judges whether the capacity of a disk is so sufficiently large that the screenshot data can be stored; if the capacity of the disk is sufficiently large, the screenshot data is stored in the disk according to an appointed path rule; otherwise, the screenshot is stored in another disc with the sufficiently large capacity according to an appointed path rule; a database server obtains information of the screenshot data and writes the information into a data sheet in a current secondary database file, wherein the information of the screenshot data comprises the attribute of the screenshot data, and absolute path information and relative path information of a directory where the screenshot data is located. The invention provides a distributed storage scheme, and according to service requirements, the directory structure of each level is optimized from multiple angles, and the screenshot information database is built; therefore, performance of searching, moving and canceling screenshot files are improved.

Description

technical field [0001] The invention relates to the field of data storage, in particular to a video screenshot storage method and system for easy retrieval. Background technique [0002] The main characteristics of video capture at expressway toll stations, expressway speed measuring points, railway station security checks, airport security checks and other places are small files, large quantities, long storage period, and a large number of disk fragments will be generated after being stored on the hard disk; It has a serious impact on operations such as file reading, moving, and deleting. [0003] At present, most relevant software products on the market use only storage for screenshot storage, and other delete, move, and read performance operations are not carefully designed; resulting in that when the hard disk storage is full, you cannot move files for a long time if you want to delete or move them. Taking video screenshots as a unit of 50kb each, when the number of pic...

AI Technical Summary

Problems solved by technology

Frequent hard disk reading during this period will greatly shorten the life of the hard disk and easily cause hard disk failure

Therefore, it is necessary to optimize the design of the storage structure of the stored pictures to overcome the deletion, movement, and retrieval performance problems caused by a large number of screenshots of the folder.
