The Research On RFID(Radio Frequency Identification) Based On Automobile

This article gives a systematic introduction to the present RFID applied in different fields, through its theory, formation system, classification and working style. And through the knowledge of RFID technology, the real state which the author develops in our country according to present demand and RFID, having proposed a real application of RFID, that is to use RFID technology on vehicle. Utilize RFID technology to carry on systematic, intelligent management to the vehicle. And dove the overall introduction to the development of vehicle RFID system and every technology.The railroad Auto train Identification System (ATIS) which is a kind of the vehicles Radio Frequency Identification system, is playing the major role in the railway administration. In our country, Ministry of Railways has already appeared the corresponding temporary technology standard on this domain. According to the Ministry of Railways "Railroad Auto train Identification System Temporary Technology standard", This paper has designed a set of ATIS system, and discussed the vehicles radio frequency identification system from the principle and the constitution.The ATIS design provides several design options about the section for technology standard, the ground identification equipment and the tag fault-tolerant and so on. The stability, reliability and expansion for the whole system are determined by the design of these aspects. Adopted by relevant information, the design can be made in the application of information management technology ATIS, power amplify, microwave reflector technology, and a variety of labels disk technology.At the same time, throughout the ATIS, readers with tags, antennas, almost all have close contact plane, which is the core of ATIS components. The design mainly is based on the technical specifications of the Ministry of Railways to design the request readers.Through the constitution working methods and the chips of readers, this article prominently introduces the design of ATIS readers with tags which working frequency cut between 910.2MHz/912.2MHz/914.2MHz. It can identifying 0~6 meters in distance, and radiation power achieve 2W. the design conforms to the technical standards ISO10374 readers design.Finally, this paper has introduced the ATIS functional and technical design parameters. And practical applications and works done on-line debugging.
