Design And Implementation Of Pro-Active Moving Video Monitoring System Based On GPRS

With the development of the embedded technology, network technology and communication technology, security monitoring system is to the direction of the smaller, mobile, and active, so pro-active remote home video monitoring will slowly slip into a trend. In this paper, with a combination of embedded systems and GPRS communication technology, design and implement a pro-active home mobile video monitoring systems. Through the platform, once the monitoring equipment detect anomalies, it will take the initiative through the GPRS network to send SMS, Email or MMS message to the user. And after users receive the information, they can also use mobile applications to view live images and video or video designated historical timeto understand the situation at home.The whole system is divided into three parts, including forward server, on-site monitoring terminal and mobilephone application based on Windows Mobile operating system. on-site monitoring terminal which is the core of the whole system, mainly completes the on-site monitoring the situation, live video recording, alarm handling and the provision of video, image, voice services.First of all, paper introduced the current status and development trends of video monitoring system, introduced the prospects for the development of mobile security. Then this paper introduces the use of the system hardware and software platform, aswell as embedded Linux development platform and mobile application development platform. Then study in the GPRS network point-to-point communication. Then focuson the point-to-point communications under NAT, the UDP sliding window protocol application based on GPRS in the subject and raise an effective transferring mothod. Then studied the mothod to send SMS, Email and MMS through the GPRS module. Finally give the design of programs, including design ideas and the realization of modules of forward server, on-site monitoring terminal and mobilephone application. Finally, do a brief summary to the work and follow-up put forward how the next stepshould be carried out.
