Design Of Embedded Interface In Video Surveillance System Based On Internet

With the rapid development of internet and embedded technology, the research of embedded equipment with network function is becoming a hotspot field. With the gradual popularization of internet, more and more families could surf on internet, it's a so viable and valuable research project that transmitting the video and image datas for familial applications on internet platform. At the same time, with the progress of apparatus facture technics, embedded facility has the evident ascendencies such as low cost and powerful,steady perform- ance which are fit for family field.The paper brings forward a design plan of low-cost embedded network interface equipment used in remote video surveillance system against house environment. This remote video surveillance system was built by connecting the embedded network interface and USB camera,internet platform, consumers could use the internet PC to real-time and remote monitor houses'circses. The embedded network interface uses the powerful and great performance embedd- ed processor named ARM9 as the core of hard platform. During the design course, the paper completed the simple structure designs of storage module, network module, debug module, usb circuit and external circuit, at last built a hard platform contrapose the interface's main functions. At the same time, a free source embedded Linux operation system as the platform for softwares'design based on exist hard platform was reduced and replanted. According to the structures of linux system core and device driver's characteristic, the paper accomplished the driver designs of front video monitoring equipment and application programs based on API functions provided by Linux core against image capture and display. Finally, the paper completed the design of Socket network transmission program based on TCP/IP protocol and achieved anticipate task, people can surveillance the faraway locale real-time.The paper accomplished the anticipate design task and used the powerful embedded processor as the core of simple hard platform, so the embedded interface has some merits of powerful, higher scope of integration, low-cost, small, lower energy expenditure,etc. By using the internet as the transmission platform for excellences of fast, real-time, long distance transmission around whole internet, low-cost and simple installation, resolves the problem of cost and distance for family consumer. The paper bestows the free source and real-time embedded operation system as software platform, fulfill the program functions, avoids the problem of copyright. Research of this interface is so available and valuable.
