Design And Application Of Bank Video Supervision System

Nowadays, with the rapid development of multimedia technology and computer network and communication technology, along the new developing direction, the traditional surveillance system is also under continual update and development. Then with appearance of the embedded system technology and the urgent requirement reducing system cost and improving system reliability, the remote video surveillance will become new research focus.In this thesis, we aims at the requirements of bank video surveillance system, mainly combining embedded technology with computer network technology, designed a digital video surveillance system by using internet or LAN, which has steady property and strong process ability. The web server program runs under the embedded Linux system platform and acts as server role in the whole system. It runs by means of backstage and waits for the request of control center, thus realizes monitor in LAN or INTERNET.In the text, firstly we expatiate on the phylogeny of video surveillance system and the domestic and overseas video surveillance system development trend, then design video surveillance based on the embedded technology aiming at these features of technology, increasing the system stability and decreasing the cost.Secondly , according to analyzing the requirements of bank video surveillance system, we bring forward the whole architecture design .The whole system design is divided into three parts: hardware design,implement of Linux embedded system and software design. In hardware design part, the implement scheme is presented firstly, then analyzed detailedly the design of interface circuit of Hi3510 CPU chip with memory,video & audio data acquisition module, video and audio frequency play module,RS-232 communication module and fast Ethernet adapter module; In second depart, researched porting embedded Linux operation system to the hardware platform, the design of Boot loader is specified importantly; In software design part, mainly discusses Linux device driver, especially the implement of video controller .Finally, tests the system based on the office LAN and shows experiment result, realizes the function of remote monitor and control in LAN or INTERNET.Based on the research on this project, we supply rational solution for the bank that can meet their needs, which strengthen safe monitor and decrease the cost.
