Internet-Based Remote Video Surveillance Terminal Design

This topic based on the research and the analysis of existing video surveillance system, because of the current industrial environment monitoring system overall equipment cost is too high, put forward the design based on the Internet video monitoring system solutions of remote. The old control system, a surveillance camera needs to connect three video signal lines for data transmission, because the video signal transmission line is not far enough, and every cameras need a industrial computer, so it is very expensive and not applicable achieving large area of monitoring. This paper based on the Internet video monitoring system of remote plan, using existing network in the basis, through a server connection many cameras, each camera just pick up a piece of string can well data transmission, can enlarge monitoring area; Field camera the monitoring data collected by the network transmission to remote monitoring, and the monitoring in monitoring software control can be through the monitor terminal monitor the actions, suitable for industrial environment video monitoring remote.This paper firstly introduces the topic research background and project source video monitoring system, then expounds the development history of video monitoring system, and application of the relevant technology made certain instructions.In studied the embedded technology, on the basis of video processing development platform, the function requirements and performance demands are analyzed.in principle, the overall design was proposed based on Internet video monitoring system of remote overall design scheme, in this scheme to monitor terminal on the main processor which is needed and embedded operating system of choice, the choice of micro controller is based on the ARM920T kernel S3C2440 micro controller, embedded operating system is Linux system.Secondly, around monitoring terminal design scheme to the video terminals modules to carry on the design, mainly including:video module; Audio module; Network module; USB interface module; External memory expansion module; Power supply module; Relay circuit and J-TAG simulation interfaceAt last, according to the terminal requirements, completed the Linux operating system transplantation and peripherals driver, and use network video monitoring USB webcam to fulfill a test.
