Rfid Technology Is Applied Research In The Electronic Tag Reading And Writing Machines

Nowadays, the radio frequency identification (RFID) develops fast, the characteristics of electronic label which are small, thin, pliant and tough, makes it can be used widely. But the read-write machines for electronic label have shortcomings, which are the characteristic of responsers in the read-write machines functional area can not be measured easily. This paper puts forward a design model for read-write machines through studying the traits of electronic label and read-write machines' circuits.Firstly, the research background and the topic sources are introduced, research state of this topic in our country and abroad are summarized. Trough the concrete introduction of simulated responser test circuits and read-write machine circuits, the analysis of test cuicuits voltage changing trough the reader's magnetic field intensity changing fuctional results are given. Based on analyzing the simulated responser test circuits and reader's cuicuits, the design of antenna control circuits, most kind shapes and size of antenna are discussed. Because the research on application of RFID technique applied to reader is not enough, which makes the reader's performance is instable and the distance between reader and writer is difficult to test, the paper solves the problem, and supported the design of read-write machines theoretically and practically. Then, the application of electronic label read-write machine in IN-OUT system is introduced. After introducing the special demand in fuction and structure of the system, the communication of the read-write machine and the computer is given; then, the run result of the IN-OUT system is given. At last, after conclusion the design and application of the system, the wide application future of this technique is pointed.
