Design And Implementation Of The Video Monitoring System For School Bus Based On Wireless Networks

With the rapid development of Chinese economic, and the fast innovation of theinformation technology, operators are rushed into the communication market with fiercecompetition. Especially, the fast development of the technology of the Wireless Networkproduces the effect on every sides of the society. For instance, the monitor of the ‘school bus’is a good application which has been widely used in schools all of the country. The mostimportant advantage of the Wireless Network is that it won’t be restricted by the reticle. Wecan surf the Internet everywhere only if there covers the signal. Many kinds of applicationslike Wireless language, Wireless location and wireless video surveillance are pushed out insuccession, which bring us great convenience in our lives.The research theme in our paper belongs to the application of wireless videosurveillance. It’s a school bus video surveillance system based on wireless network, which isan indivisible part in guarantee the school safety. The surveillance system we designed andrealized include the function that can administrate the surveillance system through WirelessNetwork without regional in gradient, also it supports the function that store and share videomassage.Our system consists of three parts. The collected system is used to collect the videoinformation, and to code and decode as well. The second system is transmitted system, whichis used to transmit the information through the IP net. The third one is a manager system,which can store and administrate the whole system. The three parts interrelate and cooperatewith each other in order to complete the surveillance task. The collected system mainly usesthe camera which use infrared ray to collect data and code data.In this paper, we first introduce the technology of the video surveillance and the wirelesstransmission, and then we introduce the advantage of our surveillance system compared to theothers. Next, some core technologies are also described, which include the physics transportlayer technology based on ARM and GPRS, and TCP/IP transport protocols as well asembedded technology, QoS of streaming media, wireless safe technology, and so on. Then weintroduce the demand analysis which include both the function and performance demand. Inthe fourth chapter, overall design is introduced and the demand the school presents itself isintroduced. The demands of the function, performance and management also have beenshowed. We come up with the design thought, design principles of our school bus videosurveillance system which is based on wireless network. After that we introduce theimplement process of the modules of the system. At last, the work in this thesis is summarizedand the further steps are prospected.
