Abstract


The video system is now widely used in all aspects of social life . In various traffic junctions video surveillance systems , and a variety of image processing in the laboratory and video algorithms , you need to have a reliable video system to support . As technology advances and people require the continuous improvement of the video system , a variety of processing speed is faster , more compatibility , the external expansion richer video system continuously market . The design of the video surveillance system is more complex , it is a very broad concept . Including hardware design , software design , and algorithm design . The main work of this paper is a complete video surveillance system hardware design and commissioning work. The main processing chip of the video surveillance system is provided by the Texas Instruments (TI) TMS320DM642 DSP . The hardware design of the system include: memory module design , the JTAG interface design , the design of the clock system , the design of the power supply module , reset the system design , the design of video input and output modules , alarm circuit design . The system also expanding outside the USB interface and Ethernet interface provides a convenient , again the system development and system upgrade . The system hardware design tools is widely used Protel DXP, it can easily complete system schematic design and PCB design . System debugging module hardware design debugging , in order to ensure that the entire system can achieve the desired design effect . System debugging is completed in TI 's integrated development environment CCS . The system can provide a good experimental platform for image and video algorithms , to be supplemented by the algorithm can be widely used in the field of video surveillance and security , as well as video conferencing and other occasions . Finally, the paper also summarizes the work raised a number of deficiencies in the work place and needs to be improved , and the direction of future research prospects .
