The Design And Implementation Of Remote Monitoring System Based On Linux

Use technology to bendfit humen’s life is the themes of our era. With the help of wireless sensor network(WSN). It can save manpower in the area of monitor environment enormously. Obviously it will be more beneficial if we can obtain the environmental data of the monitor regions as well as the local real-time video and the image data of the environment at the same time. The purpose of this paper is to design a set of remote video monitoring system for real-time monitoring.The whole system uses S3C6410 chips as the main control chip, one of products of Samsung Company. The design of the operating system is based on Linux open source system with deep customization and improvement. The abilities of the video monitoring system include real-time video data collection, MJPEG format compression, and a number of JPEG image data photographed regularly. The video transmission is through the protocol of TCP/IP, with the ability of wired and wireless transmission. Wireless transmission uses 3G network and is monitored by means of VPN connection for remote real-time monitoring.The paper mainly involves the part of selection of chip to form the system and the main hardware modules. Then it introduces the overall design scheme of the software system and the application programs needed to carry on the design of software. The system boot loader program U-boot, kernel and file system porting and design. Finally comes the design of network video server and system transmission part of the software, accompanied with the establishment of the VPN client embedded into the system and the design to imply the VPN server host. The test results are given in the end of each part correspondingly.
