Design Of Video Supervisory System Based On 3g

The third generation wireless network CDMA20000-1X EVDO has been fully put into commercial service. As the most maturely developed wireless network, it has the most advanced key technologies such as forward link design and resource scheduling., which has profound influence on future mobile communications, video transmission, monitoring system and so on. And the globalization of monitoring system, increasingly stronger function of ARM9 processor chip, and perfecting standard of video coding and decoding push forward the fast development of wireless video monitoring system.With the theme of video transmission system, this paper gives a detailed description on how to establish the software and hardware platform, and analyses the implementation procedure of 3G module by software and hardware based on chip MC8630. The work is as follows:(1) Make a study on the current situation and development prospects of remote video transmission terminal and put forward the implementation of this terminal according to the meaning of study on this subject.(2) Analyse the popular standard for video coding and decoding such as MPEG-4,JPEG and H.264. Realize the procedure of capturing for chip TW2835, which is used in this system.(3) With processor GM8180 as core, analyse the overall structure of hardware platform, and show how to design core-board such as storage system, serial port control, GPIO control and so on in detail. Describe the software architecture and the way to construct it in software platform.(4) Analyse the development history and work process of CDMA2000-1X EVDO technology from the point of 3G wireless communication network and put forward the implementation with software and hardware based on chip MC8630.(5) Centered with monitoring mainboard and surrounded with 3G board, simulate the transmission results of video transmission system.
