Design And Implementation Of The Bus Information Dissemination System Based On RFID

The Bus Information Dissemination System has good application in various fields. It’s able to disseminate the useful information to the public on the display monitor. such as disseminating the natural disaster emergency information and fire information and so on. Great changes have taken place in the bus management system, from a relatively traditional way gradually to the development of intelligent and network transport system. In the aspect of intelligent network, the application of RFID technology in the traffic is particularly great, it is significant to improve the efficiency, and the formation of the intelligent transportation system in china.There are many questions in current bus system, such as information is disseminated timelessly, resource utilization rate is low, information collection is not accurate and so on. It has many technology to acquisition data, such as vehicle GPS terminal, RFID technology, sensor network and so on. It is mainly applied to the distribution of data collection difficult situations based on sensor network.GPS is mainly applied to the location of the more stringent requirements of the applications based on RFID technology, the cost is low, RFID tags, labels can be used repeatedly, long recognition distance. To select the appropriate working labels according to different applications, the information dissemination system, to collect data by using RFID technology, is a key technology in the current. The reason is that RFID tag has a multiple object recognition, recognition speed, strong anti-interference, label use of the advantages of long service life, strong anti pollution ability, realize the data acquisition and transmission without physical contact. It is widely used in access control systems, identity recognition, high speed ETC, logistics and other fields, and has broad application prospects. Therefore, this paper is based on the design of the bus system, bus information dissemination system based on RFID, in order to make full use of existing resources to improve the utilization of the bus, the bus utilization. Research of background and research status of the structure of this paper first introduces the RFID bus information dissemination system, and the research status at home and abroad are analyzed and summarized; the basic working principle of RFID system, RFID system,.NET technology and UML modeling technology are introduced, and the analysis of the application of RFID technology in the public transport system, and then put forward the framework of public traffic information dissemination system based on RFID. Study on the key technology of the key point. At the same time, demand analysis, the overall target analysis, flow analysis, function analysis and technical architecture. Then according to RFID bus information release system functional design and system design in detail, and then the information release system based on RFID.
