Desing And Implementation Of The Pu Jiang Hua Yuan Video Security Monitoring

Along with the rapid development of China's economic level, people's life level has been improved significantly, especially the city residents living environment improved, the surrounding security more and more attention. Then in the modernization of today, some means of crime at present more and more covert, it is not easy to be found, and more intelligent. So it becomes strengthen video security monitoring technology is very important.Video security monitoring technology can correct implementation in the maintenance of social order, preventing and combating crime plays a big role. This paper is based on an area as an example, introduces the design and implementation of a video surveillance system. This video security monitoring system is also suitable for supermarkets, schools,shopping malls and so on some occasion need to monitor.This paper introduces the realization method of video surveillance system from the angle of the bottom. The main part of the video surveillance system includes a hard disk recorder, camera, keyboard control and electronic fence. Responsible for obtaining video camera, through the network to monitor the video to the hard disk recorders, hard disk recorder is responsible for the acquisition of video saved on your hard disk to consult, to control the keyboard is operating lever on the hard disk recorder, can be more easily operated by the control keyboard, the electronic fence through linkage module and a harddisk recorder the connection to play the role of warning and deterrent.This paper studies the various parts of the platform used in video security surveillance systems, including hard disk recorders Hass platform used to control the keyboard to use the new platform and platform Tang Extension of the electronic fence to use.Then study the video security monitoring system management system, linux operating systems, including Linux kernel, file system, and Uboot cut, as well as I2 C, SPI, UART bus technology.Then the main part of the design and implementation of video security monitoring system, cameras and hard disk recorders. Hass studied under the camera platform implementations and hard disk recorder. Hard disk recorder in which some of the major audio and video codec interfaces, video partially achieved ADC, infrared light control,IR-CUT, dual filters, high-speed infrared ball of implementation and realization of the auto iris.Finally, the system passes the functional and performance testing, and achieved the desired effect, at the same time the cell monitoring, electronic fence also played a role in the security of.
