Below at first the realization of the recording function in the video monitoring system is introduced:
In the video monitoring system of describing in the application scenarios of the present invention, storage is divided into three layers, is respectively Access Layer storage, convergence-level storage and core layer storage.
For Access Layer; Behind the coding video data that head end encoder arrives the front end camera collection; Be kept at local front-end memory such as local hard drive or CF (Compact Flash; Compact flash) card waits in the storage medium, and after the memory space of front-end memory was filled with, covering circulated from the starting position of the memory space of front-end memory.For example the CF card of a 8G can be preserved about 9 hours 2M video code flow, can guarantee to have 9 hours up-to-date video media-data in the local storage all the time.The life cycle of the video data of promptly in head end encoder, preserving is 9 hours.Encoder is open to the data management server of convergence-level and the data management server of core layer through network sharing mode (as: iSCSI, share directory etc.) with local storage.
For convergence-level, data management server is according to the first preset strategy, transfers the video media-data of Access Layer from the memory of the head end encoder that is arranged in Access Layer, and is saved in the memory device that is arranged in convergence-level; This transfers process also can be described as data management server according to the first preset strategy; The video media-data of storing in the memory to the head end encoder of Access Layer is screened, and the video media-data that meets the first preset strategy after the screening is saved in the memory device that is arranged in convergence-level.The data management server of convergence-level will be arranged in the memory space of the memory device of convergence-level and share to the data management server that is positioned at core layer through the network sharing mode.Generally; The memory space that is positioned at the data management server of convergence-level adopts the storage area network technology like IP SAN, FC (Fiber Channel; Optical-fibre channel) SAN etc.; And the retention phase of the data that the memory device that its retention phase is arranged in Access Layer is stored is long, and the retention phase core layer that is arranged in the data that the memory device of core layer stores is short.
For core layer, data management server is transferred corresponding video media-data from the memory device that is arranged in convergence-level, and is saved in the memory device of core layer according to the second preset strategy; This transfers process also can be described as data management server according to the second preset strategy; The video media-data of storing in the memory device to convergence-level is screened, and the video media-data that meets the second preset strategy after the screening is saved in the memory device that is arranged in core layer.Generally, the memory space that is positioned at the data management server of core layer adopts the storage area network technology like IP SAN, FC SAN etc.Also have center management server in the core layer, be used to formulate first strategy and second strategy, first strategy is sent to the data management server in the convergence-level, second strategy is sent to the data management server in the core layer.
