ASIC Design Of RFID System Applied To Automobiles Administration By MCU(89C51)

RFID(Radio Frequency Identification) system is a high efficient information collection and identification system. It has many advantages, such as abundance of data information, high security of data, great ability of anti-EMI(Electro Magnetic Interference), short recognizing time and low cost. Therefore it has a promising future, such as in application to electronic street nameplate, to system of ticket service, to automobile management, to assembly line administration. In this paper, I first studied basic theories of RFID system, including algorithms of encryption, error correcting codes, theory of CRC(Cyclic Redundancy Check), techniques of EMC (Electromagnetic Compatibility), I/O techniques of SCM(Single Chip Micyoco). Then, I designed the project of RFID system applied to automobiles administration, hierarchical structure of data stream and structures of reader and responder. Then, I designed circuitries of reader and responder, made showpiece of them, then OS(operating system) programmed by C51, emulated and debugged by Wave In-circuit Emulator. After being tested and optimized, a qualified RFID system has been completed, which implemented the project. In conclusion the design has great expansibility and is the theory and practice base of integrated(ASIC & MCM) RFID system applied to automobiles administration.
