Intelligent Transportation Systems (ITS) is the world's transportation frontier research. Traffic information video detection technology in an intelligent transportation system as a key technology and the important part , as opposed to other traffic information detection technology has great advantages. Papers in the analysis of the domestic and international traffic video detection technology , based on the existing traffic video detection system for the presence of bulky, difficult to improve processing speed , low reliability , high cost , extensions and maintenance inconvenience other shortcomings, combined with practical application, design and development of a high-speed image processor DSP chip as the core of networked embedded traffic video detection system. The system consists of plug-in video detectors, switches, servers, composed of three parts , each of which can be installed detector 16 detects the card , each card can independently detect real-time processing a way standard video signals, with video decoding, video compression, video image processing, traffic incident detection , traffic statistics and parameters sent to the server test results and other functions. Switch is responsible for detector and a high-speed Ethernet communication between servers . Server is responsible for storing information about traffic events , traffic measurement parameters , events, video clips and other data as well as the camera detects the initial background , lane information , algorithm processing threshold initialization parameters such as cameras , as well as providing client access historical data communications interface . Thesis completion of the system functional requirements analysis, system demonstration program , video card detection hardware circuit design, system power integrity , signal integrity and electromagnetic compatibility theoretical analysis and research , the system speed PCB board design and development as well as the associated system software and hardware tune and test work. Dissertation research and development of the network traffic video detection hardware system has been successful in several practical projects to be applied , the application of the results showed that: the system is stable , reliable , full-featured , able to meet the needs of practical application for traffic video detection areas provide a good solution .
