The Design And Implementation Of Network Video Monitoring System Based Embedded Web Server

With the blowout development of computer technology,communications technology and network technology,The of video surveillance that plays an important role in the field of security comes to be the concern,The remote of video surveillance(that is network video surveillance)becomes a trend by the Internet,It uses PnP monitoring methods,and where there is the local network coverage,there is real-time monitoring Anytime and anywhere on the target sites.Network video surveillance system can be used B / S and C / S in two modes,in which the user B / S mode is accessed through a browser on a video server,access to video recording.This paper is based on this core idea,completed the design and implementation of network video surveillance system.There are the main work and innovation of this paper:(1)By analyzing the background,domestic and foreign Situation,development trend of video surveillance system in-depth,there is an overview of the composition working principle,key technologies involved and development methodology of conventional embedded Linux operating system of the network video surveillance system based embedded Web server.(2)The combination of practical experience in anko,there is a design of network video surveillance based "IP camera NVR" type.The implementation of the program relies on embedded Linux operating system,embedded microprocessors,network cameras IP camera,embedded Web server and other modules,the key of complement of the program is to build the system development platform,involving the establishment of cross-compiler environment,the selection and transplant of Boot Loader,implementation of Yaffs root file system and the cutting and transplantation embedded Linux kernel.(3)At the front end of Collection about the video Database,this paper uses a built-in IP address of the network camera(namely IP camera),The advantage is that authorized user on the client can use this IP address to access directly to the IP camera,to get HD video streaming data,improving greatly the operability and the real-time of the monitoring.(4)In aspects of the video server,combined with the latest trends and exploring of the embedded server,the subject achieve an embedded Web server builded rapidly,using Java Applet to complete the preparation of Web page,which can complete the transmission of the streaming of video and playback.
