Shenzhen subway data monitoring memory system successful case

Huicong safe guard net the news Shenzhen subway first phase has been Shenzhen municipal construction city invests the biggest national key project, is also receives the community attention the popular sentiment project. Shenzhen subway 1 line first phase, window of from Luohu to the world, has put into service in December, 2004. The Shenzhen subway 1 line subsequent construction the project, stands window of by the world to the Shenzhen Baoan international airport, supposes 15 stations. Subsequent construction in project all stations, the transformer substation, how to use the newest technology to construct set of high performances high, reliable, the high stable synthesis peaceful against system, becomes focal point question which Shenzhen subway most pays attention. The Shenzhen subway 1 line subsequent construction the project to synthesize the safe guard system is by the safe guard network sub-system, peaceful against to integrate the management subsystem, the synthesis television surveillance subsystem small steelyard system composition. The overall system uses two network constructions: The backbone level and the turning on level, the backbone level uses the pair of 10,000,000,000,000,000 ring circuit redundant structure, an entire subway line various stations interconnection; The turning on level primary cognizance various stations internal message control, the transmission and so on, and become the entire 10,000,000,000,000,000 networks a node, the subway digitization peaceful against monitoring camera system form in the turning on level network system. The star full science and technology succeeds by its VSTOR family product is selected a Shenzhen subway line to subsequent construction the project video frequency monitoring camera to save the project. The subway subsequent construction the project safe guard monitoring camera system request to select the digital compression method, to carry on the image transmission, the memory and the inquiry. Altogether has 1105 monitoring cameras, the image coding form is H.264, achieves the 4CIF/25 frame/second image clarity, namely 3Mbps symbol stream. The video image and the control use the unified TCP/IP agreement transmission, realizes the transparent transmission, all image storage time above 168 hours. The video frequency source data through the camera (security officer equipment), the encoder, the switchboard, the video frequency server arrives at the star full storage device finally, completes whole set digitized video frequency monitoring camera data the memory (security camera equipment), the entire memory system can process under the 3Mbps symbol stream, is most greatly concurrent 180 groups to storage device's pressure; Has solved in the FC host interface, under the SCSI floppy disk connection, the single wrap system achieves 64 positions the storage capacity demands; Solved local saved the mix pattern which +SAN saved to issue the subway to the video frequency supervisory system data secure request; Shenzhen subway choice star full storage device's another substantial clause also lies, the star full VSTOR family storage device based on the independent research and development, the peaceful against supervisory system request entrance guard, the platform, the memory, the server unifies completely in the identical platform carries on the monitoring and the dispatch, requests the equipment supplier to be able to provide the equipment interface parameter, even is the product program code, the star full storage device may maximum limit coordinate the project the progress, displays the highest project affinity and support dynamics.from: cctv security equipment
