Multiple Controllable Fpga Digital Video Surveillance System

In this era of rapid development of science and technology, social development requirement makes the technology move forward. High-performance, flexibile, multi-functional video surveillance equipments come out one after another. They bring security and convenience to us.The deep-going application of electronic equipment digitization promote the video surveillance develop towards new field. Digital video surveillance system has strong anti-interference ability. We can make digital video processing, and easily store and retrieve video record as well.So the digital video surveillance system has extensive application prospects.FPGA devices and design softwares are constantly updating. Their performances are better than before, as they bring us more useful features.The current research on FPGA-based video surveillance is gradually going deep.They are not only used in Industrial and civil surveillance, but also in military applications.We give out a kind of digital video survilliance system used in tanks and armored vehicles in this article, which is based on Altera FPGA.The output video of the system can be controlled, and it has high resolution. The design makes full use of resources on the FPGA chip. It makes tanks, armored vehicles have 360 degrees eyesight. The hardware logic on the FPGA which is based on modual design can be upgraded to achieve more functions.The whole sysytem on programmable chip is constructed by SOPC Builder software.The development of digital video surveillance is discussed in the artical as well as the current situation. The hardware design and the theory of the multi-channel video monitoring system is briefly described in this artical.According to the practical application of video survilliance system, we design and debug the hardware system. We also research on the 12 channel video output and control, and then design the SOPC system on FPGA chip.We design the I2C controller, SDRAM controller, VGA display modules, and so on. Then we debug them exceprt for the I2C controller and achieve our goals.
