Problems solved by technology

If all the data before 3 days is not backed up, it will be completely overwritten and cannot be queried
[0013] It can be seen that the existing technical solution unifies the data management time into a fixed long time, and all data will be overwritten after the data life cycle is reached. In the case of no backup measures, the previously stored data will not be queried

Embodiment 1

[0044] When EC supports image layering technology, its coded video surveillance data is divided into basic layer and enhancement layer. This embodiment describes the storage management process of video monitoring data including the basic layer and the enhanced layer.

[0045] In the embodiment of the present invention, when allocating IPSAN logical storage space for video surveillance data, each basic unit of the IPSAN logical space of the IPSAN device is divided into a basic data area and at least one enhanced data area. In the embodiment of the present invention, each The quantity of the enhanced data area contained in a basic unit is not specifically limited, and may be greater than, equal to or less than the number of enhanced layers of the video surveillance data. Preferably, the quantity of the enhanced data area contained in each basic unit is equal to that of the video surveillance data. The number of enhancement layers is the same. The space of the basic data area is...

Embodiment 2

[0079] When the EC does not support the image layering technology, the encoded video surveillance data will not be divided into the base layer and the enhancement layer. This embodiment describes the storage and management process of non-hierarchical video surveillance data.

[0080] In the embodiment of the present invention, when allocating IPSAN logical storage space for video monitoring data, each basic unit of the IPSAN logical space of the IPSAN device is divided into a basic data area and at least one enhanced data area, and the space of the basic data area is larger than each Enhance the space of the data area. Among them, the number of enhanced data areas can be set according to needs, and the division method can be as follows Figure 4 shown.

[0081] When there is video surveillance data that needs to be stored in the IPSAN storage device, the IPSAN storage device stores the video surveillance data into the IPSAN storage device in units of time (such as seconds). ...

Abstract

The invention discloses a data storage management method and equipment thereof. Each basic unit of an Internet protocol storage area network (IPSAN) space is divided into a basic data region and at least one enhanced data region. The method comprises the following steps of: receiving video monitoring data with a basic layer and an enhanced layer by using storage equipment and writing the basic layer data into the basic data region and the enhanced layer data into each enhanced data region according to the video monitoring data of each time unit; when the basic data region of the last basic unit is fully written, starting to rewrite from the basic data region in the first basic unit; when each enhanced data region in the last basic unit is fully written, starting to rewrite from the corresponding enhanced data region in the first basic unit; and building index information by using the storage equipment according to the storage conditions of the video monitoring data.

Description

technical field [0001] The invention relates to video surveillance technology in the field of communication technology, in particular to a data storage management method and equipment thereof. Background technique [0002] At present, the use of IPSAN (IP Storage Area Network, IP Storage Area Network) for data storage in the monitoring system is widely used. The typical network of video surveillance system is as follows: figure 1 As shown, the front-end equipment and the central equipment communicate through the IP network. The front-end equipment mainly includes a camera, EC (Encoder, encoder); the central equipment mainly includes: VM (Video Management, video management server), IPSAN, DM (Data Management Server , data management server), MS (Media Switch, media exchange server), DC (Decoder, decoder), VC (Video Client, video client), and the corresponding software management system and network transmission equipment. in: [0003] EC: Located at the front end of the mon...
