Problems solved by technology

[0004] Under the above storage system, whether it is data storage, preview, playback, etc., the main control CPU of the DVR needs to perform a large number of operations, occupying a large amount of I / O resources of the CPU, and the system performance is reduced. Moreover, the video data is scattered in each DVR. The hard disk is not conducive to the effective management of video data

Abstract

The invention provides a data storage system in video monitoring and a method for storing, previewing and reviewing data. The data storage system comprises a management platform and at least one DVR, wherein, each DVR is connected with an embedded PCI-E card; the embedded PCI-E card is connected with the management platform through a storage network and used for receiving and storing video data according to an instruction of a main control CPU of each DVR connected with the card; the management platform is connected with the embedded PCI-E card on each DVR and acquires the video data connected to the embedded PCI-E card; and the management platform manages the video stored on the embedded PCI-E card by an iSCSI mode. The invention lowers I / O expenditure of the main control CPU, improves system performances and realizes centralized management of scattered video data in each DVR through the management platform by adopting an iSCSI technology.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a data storage system and data storage, remote preview and remote playback methods in video monitoring. Background technique [0002] In digital video surveillance, especially in the case of real-time monitoring, a large amount of video data needs to be stored for use, and how to store video data reasonably, and realize fast remote preview and remote monitoring when needed through the management platform Playback is an important topic within this technical field. [0003] In the prior art, video data is stored mainly by using a local hard disk of a DVR (Digital Video Recorder, digital video recorder). The storage system structure is as follows figure 1 As shown, the DVR is connected to each DSP (Digital Signal Processing, digital signal processing) device through a PCI (Peripheral Component Interconnect, peripheral component expansion interface) bus, and each DSP is us...
