Abstract


The Embedded Remote Video Surveillance System is a kind of new video surveillance system realized by embedded technology, video coding technology and network transmission technology. The system better performance in the aspect of stability, real time, processing speed, functionality, price, scalability, etc than the traditional video surveillance system, and also represents the development of current video surveillance systems.The thesis describes the applications and general development of video surveillance systems, and then proposes a solution of embedded remote video surveillance system based on FPGA and ARM embedded system. The system is mainly composed of a professional video processing and microprocessor HI3512 and Linux operating system which manager the application software such as capturing video information, encoding/decoding, transmission, processing. The FPGA is also used to realize the E1 standard network protocol for remote transmission.Particularly to the video transmission fluid, clear screen, etc, it analyzed the key technology of realizing ,and then the E1 standard network protocols is used for video data transmission on FPGA. In the aspects of hardware designing, details of the overall scheme of the system hardware and individual hardware module are descried, including the system power supply module, video analog-digital conversion module, video isolation module. And then studied the signal integrity and power integrity from the perspective of the overall design of the system . And in the aspects of software designing, after researching the development platform of the embedded Linux system. Some main application software such as video capture software, encoding software, storage software and transmission software are designed. In the details of video transmission, the realization of E1 standard transport protocol based on FPGA is particular described, And then tested and validated the performance of real-time video data transmission and packet loss rate .The system designed in this thesis combined the advantages of the Embedded systems combine and remote transmission, And so it is innovative in some aspects and also practical in monitoring application. Overall, the last performance of the system matched its exported requirments.
