Embodiment 1

[0024] like figure 1 As shown, embodiment one provides a block storage system for video surveillance data, the system includes:

[0025] A memory 106 for storing video monitoring data, and the memory is provided with a continuous storage space;

[0026] The data block conversion unit is used to divide each data block in the multi-channel video surveillance data into at least one data block 104, and communicate with the memory in units of data blocks; wherein, the data block conversion unit can be arranged inside the video surveillance, Can also be a separate module;

[0027] The serial communication unit 105 is configured to store the data blocks sequentially in a serial communication manner in a continuous storage space or read the data blocks 104 from the continuous storage space.

[0028] continued see figure 1 , preferably, the video surveillance data block storage system is also provided with data buffers 101, 102, 103, and when the data block 104 is written into the m...

Embodiment 2

[0038] The difference between this embodiment and Embodiment 1 is that a cache device (also referred to as a buffer or a buffer device) can be directly arranged in the video surveillance equipment, and the block storage system of video surveillance data is directly connected with the video surveillance monitoring system. devices to communicate. Specifically, such as image 3 As shown, the video monitoring data system provided by this embodiment includes:

[0039] Multi-channel monitoring equipment 201, 202, 203, 204 for collecting video surveillance data, and each channel of data in the multi-channel monitoring equipment is divided into at least one data block, and the data block is used as a unit;

[0040] A memory for storing video surveillance data, and the memory is provided with a continuous storage space; wherein, the storage space is provided with continuous sector partitions, and in the sector partitions, each partition is provided with an identification sector in a p...

Embodiment 3

[0045] In this embodiment, on the basis of Embodiment 1 or Embodiment 2, the memory is divided into two different large areas, the first large area is used to store backup files; the second large area is a continuous sector partition, It is used to implement the continuous storage space in Embodiment 1 and / or Embodiment 2; in this way, video surveillance data storage is more secure. Moreover, the sector partition data is also written into the first large area for backup files in a predetermined order; preferably, the first area can be set to read video surveillance data, while the second area can be set to write video Surveillance data; this enables simultaneous and fast read and write of video surveillance data.

Abstract

The present invention provides a blocking storage system of video monitoring data. The system is characterized by comprising: a memory used for storing video monitoring data and provided with a continuous storage space; a data block conversion unit, used for dividing each-path data of multi-path video monitoring data into at least one data block, and communicating with the memory in a unit of data blocks; and a serial communication unit, used for storing the data blocks into the continuous storage space sequentially in a serial communication manner or reading the data blocks from the continuous storage space. According to the storage system of the video monitoring data provided by the present invention, the problems of lowering read / write efficiency of a disk and reducing service life of the disk, which are caused by keeping moving a head of the disk to perform a positioning write operation by a parallel processing mode of the disk when multi-path videos are written, are avoided.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a block storage system for video surveillance data. Background technique [0002] In video surveillance system, data storage is a very important technical issue. The storage of video surveillance data generally adopts digital compression technology, and stores the data in the form of files on the hard disk. As time goes by, the disk needs to constantly delete old files and record new files. Therefore, there may be a failure of the hard disk due to frequent read and write operations, thereby causing loss of video surveillance data. [0003] In order to solve the above-mentioned technical problems caused by frequent read and write operations, in the patent application with the Chinese patent application number CN201410730092.9, a hard disk without formatting is disclosed. A technical scheme for storage in a zone logic access mode, the technical scheme includes: the da...
