Embodiment Construction

[0027] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0028] figure 1 It is a flow chart of storing video surveillance recording data in a specific embodiment of the present invention. Such as figure 1 As shown, the process includes the following steps:

[0029] Step 101, format the disk on the storage server to ensure that no task files are stored in the disk, and then create a file with a fixed size on the common file system of the storage server. The size of the created file is usually 200MB.

[0030] Step 102, write file status data and file identification in the header of each file, the file status data must at least include storage file length, video surveillance point identification, video surveillance video data format version, video surveillance video data decoding The global parameters and the last modification ID of , where the last modif...

Abstract

The invention discloses a method for storing surveillance video data, comprising the following steps of: creating a file with a fixed size in a general file system of a storage server; writing file status data and a file identifier at the head of each file; searching for a free file according to the file identifier when the storage server starts to execute a video recording function; receiving surveillance video data from a network by the storage server; dividing the surveillance video into block data and writing the block data and description information thereof in the free file, and updating the file status data and the file identifier. By adopting the technical scheme, the concurrent processing capacity of the storage server is obviously improved and the use cost of the system deployment and the utilization of a network video surveillance system are reduced.

Description

technical field [0001] The invention relates to the technical field of electronic information, in particular to a method for storing video surveillance video data. Background technique [0002] With the continuous development of technology, the network video surveillance based on broadband communication technology has been widely used, and the storage server based on disk array technology has become an important functional module of the network video surveillance system. The use of RAID5 technology greatly improves the stability of video surveillance video file storage. Enterprise-level disk arrays can support tens of terabytes of storage space, but storing video surveillance video files is a highly concurrent disk writing application, and disk IO becomes a performance bottleneck. The capacity cannot match the video surveillance business needs. [0003] The reasons affecting the performance of the storage server in the network video surveillance system include two aspects:...
