Rfid In Their Own Turn To Applied Research, In The Rail Car

As a newly developed automatic identification technology, RFID (Radio Frequency Identification) is currently widely applied in the fields such as procurement and distribution of goods, trade, logistics and so on, and it mainly for automatic toll use in transportation. However, it is still seldom applied to vehicle automatic control. For the following features of railway transportation such as higher-speed operation, higher transport capacity, lower cost, safe and comfortable, less harm to environment and so on, we put forward the concept and modeled for a kind of single-railway car.On the basis of the Beijing Natural Science Foundation Project and Beijing Municipal Education Commission's Key Project, Study of Auto-veering suspended single-railway car and it's railway structure, this subject set up a applied model of RFID used in auto-veering railway car, and put forward related resolvent, that is to use tags of RFID system as memory units of roadway information, reader as an information collection system installed in the car, the micro-processor as the processing unit of gathered information and generating unit of controlling signals, as to control veer of the car.In this paper, it firstly introduces several kinds of currently used navigating methods of intelligent vehicle, compares and analyzes these methods in detail, and put forward advantages to use RFID. Then, it describes structure and technology theory of RFID system, mainly introduces structure of reader in RFID and the design of UHF reader. After that, it describes design of system applying RFID to auto-veering car, which includes hardware connection and coding. At last, it brings forward some suggestion on the father research based on this subject.RFID standard is being established step by step, and being spread and supported by the state, so it makes great sense to apply RFID to auto-veering car. Firstly, to use RFID technology in such a system, not only brings forward a novel navigating method of railway car, but also extends the application of RFID in transportation at a certain extend. Secondly, the high-speed recognizing makes RFID adapt for the railway traffic which is character of high travel speed, and combination of RFID and GIS makes a completely system. Thirdly, to design a kind of reader that can gather information, process data and control the train makes a great sense. It can make enough use of the hardware and reduce system redundancy. Finally, the system using RFID can be easily extended in the next research.
