摘要
介绍了基于DSP实现RFID超高频(UHF)射频识别系统的方法,该系统采用TMS320F2812DSP作为主控芯片,AS3991作为无线收发模块,基于EPCGEN2协议实现RFID读写器对标签的识别、读写等操作。DSP的使用简化了射频系统的复杂度,使得该系统具有低成本、通信稳定、操作简单等优点,应用前景十分广阔,对RFID的推广具有一定的指导意义。
This paper introduces an UHF RFID system based on DSP technology. TMS320F2812 is used as MCU and AS3991 as RF transmitter, meanwhile EPC GEN2 protocol is used in this system to fulfill identifying, reading and writing the tag. DSP used in RFID helps to reduce the complexity and make design more convenient, which brings the system having low costs, reliable communication and simple operation. It can be anticipated that the system this paper putting forward will have widely application in the future and have somewhat instructional significance in spreading RFID.
