Bank Atm Machine, System Design, Embedded Network Video Surveillance

The dissertation is derived from a project, which is to design a kind of embedded network video monitor system used by ATM of the bank. Based on embedded technique, the system realizes the function of monitoring video via network, by cooperating with video collection, video compression and network transmission technique.At the beginning of the thesis, the development, status quo of video monitor and the outlook of embedded network video monitor system is discussed;then two kinds of basic technique,video compression and network transmission,used in network video monitor system,are introduced;to the demand of ATM video monitor,we do the overall design,analyse the function demand and select the core chip of system;after the overall design,the system hardware design is detailedly introduced, including video collection module, video compression module, network controller module,sensor and logic control module;at last,with the TINI platform of network controller chip DS80C400 and Java language, correlative software design is briefly introduced to integrate the whole project. The system printed-circuit board and preparatory software are now completed and the system can realize the function of video monitor via network.
