File storage system for accelerating simultaneous playback of multiway monitoring

Abstract

The invention discloses a file storage system for accelerating simultaneous playback of multiway monitoring. When the file storage system is used for the first time, a disk is formatted to form 4 partitions including a system attribute partition, a date index partition, a file index partition and a data block partition; the format of a partitioned file is reset; when a video is played back, by directly reading and writing the file storage system, a server retrieves a primary index partition through a time period parameter to obtain an index record of a date of a time period, retrieves a secondary index partition through a recorded offset address field value to obtain initial offset addresses of all video data blocks in the time period corresponding to the date, extracts data and returns the data to a client; and the primary index partition takes the date as a retrieval standard, the secondary index partition takes a block timestamp and a block type as retrieval standards, and accordingto the setting of secondary index contents, the purpose of quick data retrieval is achieved. By adopting the file storage system, the problem of low disk storage, reading-writing, search and locatingspeeds during playback operation of a multiway monitoring device can be effectively solved.

Description

technical field [0001] The invention relates to the field of audio and video monitoring and file storage systems, in particular to a file storage system that speeds up multi-channel monitoring and simultaneous playback. Background technique [0002] FAT32, NTFS and other file storage systems on the traditional Windows platform can meet the needs for small data storage, reading and writing, searching, querying and exchanging operations. With the increasingly complex social security situation, video surveillance engineering has become a social security Important guarantee, video monitoring equipment and monitoring data are growing geometrically. For operations such as large or even massive data storage, reading and writing, and searching, such as when operating multiple monitoring equipment at the same time, the traditional file storage system hard disk data storage, The reading and writing speed is slow, the efficiency is low, and even it cannot be operated; at the same time,...

Problems solved by technology

[0002] FAT32, NTFS and other file storage systems on the traditional Windows platform can meet the needs for small data storage, reading and writing, searching, querying and exchanging operations. With the increasingly complex social security situation, video surveillance engineering has become a social security Important guarantee, video monitoring equipment and monitoring data are growing geometrically. For operations such as large or even massive data storage, reading and writing, and searching, such as when operating multiple monitoring devices at the same time, the traditional file storage system hard disk data storage, The reading and writing speed is slow, the efficiency is low, and even it cannot be operated; at the same time, the more files stored in the traditional file storage system, the greater the burden of sector area management, the more files are stored, the slower the storage speed, which cannot satisfy some When a major case occurs, the video needs to quickly view video resources and play back, etc.

[0003] At present, in order to facilitate monitoring data retrieval and data recovery, many file storage systems store data in units of blocks, and establish one-level or multi-level indexes to achieve the purpose of fast storage, but the contents of the first-level or second-level index areas and formats, and cannot fully meet the needs of storage and fast playback of multi-channel monitoring equipment
