| With the continuous development of network technology and communication technology, remote video surveillance technology has obtained the rapid development. Monitoring system is widely used in key industries such as public security and traffic control. This article has studied the remote monitoring system based on3G network, using3G technologies to complete the wireless transmission of remote video data.This article first explored the background meaning of the subject, the development history and trend of surveillance technologies. Secondly elaborated the basic theory of wireless remote video monitoring system based on3G technology, then from both hardware and software discussed the design and implementation of video monitoring system. Finally, the article summarizes the achievement of this subject and analyzes the deficiency of system.The hardware platform of this paper is DM6446embedded development board based on DaVinci technology. The hardware design mainly introduced the block diagram of the remote monitoring terminal of system, the core chips TMS320DM6446, ARM module, DSP module, and video processing module. This paper mainly realized the design and implementation of client and server of monitoring system, uses Microsoft Visual Studio2005as developing environment, chooses C#as the development language, uses SQL Server2005to build the database of system; Uses ASP.NET technology to design dynamic browser page of the video monitoring system and realizes the data information interaction between server and system’s database by the ADO.NET technology which is suitable for visiting the network database. User can be convenient and efficient to inquiry remote monitoring system by Web pages. |
