Problems solved by technology

[0009] The purpose of the present invention is to provide a method and device for video surveillance data backup, so as to solve the problem that the performance of the VOD module is not enough when the backup server performs video surveillance data backup through the VOD module in the prior art or the backup server directly reads the video surveillance data from the data storage device. When data is used for backup and storage of video surveillance data, it will greatly affect the performance of data storage devices

Embodiment Construction

[0048] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.

[0049] The network structure of video monitoring data backup in this embodiment is as follows: figure 1 As shown in the figure, IPC is the camera, IPSAN is the data storage device, and the video management server is used to manage the corresponding relationship between the camera and the backup server and the backup time requirement of the monitoring video data of each camera, and interact with the camera and the backup server through iSCSI linkage Message information. The video data captured by the IPC is sent to the data storage device IPSAN through the switch A, and the switch A encapsulates the video data into a UDP data packet and sends it to the backup server or the gateway device of the backup server.

[0050] The method for...

Abstract

The invention discloses a method and device for backing up video surveillance data. The front-end equipment constructs the video surveillance data as a linkage message to send, and the network equipment in the video surveillance system receives the data packet from the front-end equipment to judge whether it is an agreed linkage message. If it is, the monitoring video data in the linkage message will be packaged and sent to the data storage device, and at the same time, according to the backup server and its gateway information obtained by parsing the linkage message, the monitoring video data in the linkage message will be packaged and sent to the backup server. The device of the invention includes a receiving module, a judging module and a sending module. The method and device of the invention will not generate extra IO overhead and influence on the data storage device, and improve the backup efficiency.

Description

technical field [0001] The invention belongs to the field of video monitoring, in particular to a method and device for backing up video monitoring data. Background technique [0002] With the continuous development of video surveillance technology, video surveillance has been widely used in various industries. In many departments that require high security and reliability of video surveillance data, such as public security departments, banks, etc., in addition to normal storage of video surveillance data, some important video surveillance data must be backed up through a backup server save. [0003] The video monitoring data captured by the camera is generally stored on the storage device through the IP network using the iSCSI protocol. The iSCSI protocol is a SCSI instruction set that can be used by hardware devices and can run on the upper layer of the TCP protocol. This instruction set can be implemented on the TCP The SCSI protocol runs on the / IP network. The main fu...
