Method, system and management node for cloud storage of video data

Abstract

The invention discloses a method, system and management node for carrying out cloud storage on picture recording data, wherein the method comprises the steps that: the management node receives a picture recording plan, extracts a front end equipment address from the picture recording plan and queries an access node list for a video access node identifier corresponding to the front end equipment address; if the querying is successful, the picture recording plan is issued to a video access node corresponding to the video access node identifier; if the querying is not successful, a video access node is selected, the picture recording plan is issued to the selected video access node, and the picture recording plan is added to the identifier, corresponding to the selected video access node, in the access node list; and the video access node execute the received picture recording plan, picture recording data is obtained from front end equipment, and the picture recording data is sent to a storage node for storage. According to the scheme provided by the invention, the successful access to the picture recording data is ensured, and the storage requirement of the mass data is met.

Description

technical field [0001] The invention relates to video data storage technology, in particular to a method, system and management node for cloud storage of video data. Background technique [0002] In the video recording technology, the recording scene is collected to obtain the recording data; a front-end device corresponds to at least one channel, and the front-end device obtains the recording data of the corresponding application scene through the designated channel according to the recording plan and stores them. [0003] Existing front-end equipment is, for example, a Network Video Recorder (NVR, Net Video Recorder) or a Digital Video Recorder (DVR, Digital Video Recorder). The current method for storing video data is: directly send the video recording plan to the corresponding front-end equipment such as DVR or NVR, and the DVR or NVR executes the video recording plan. [0004] The recording plan includes the address of the front-end device that needs to acquire video d...

Problems solved by technology

[0006] When the application establishes a connection with the DVR or NVR for access, due to the limitation of the maximum number of connections of the DVR or NVR, if multiple users need to access the same DVR or NVR at the same time, they will not be able to connect all of them, resulting in request failure; Moreover, due to the limited storage space of DVR or NVR, it cannot meet the storage requirements of massive data
