摘　　要：针对目前市场流行的超高频RFID识别系统成本高、制作方法复杂等问题,提出了一种基于射频读写专用芯片MagicRF M100的兼容国际标准ISO/IEC 18000-6C和EPC Class-1 Generation-2协议的UHF RFID读写器的设计方案,详细阐述了读写器的工作原理,并相应地介绍了系统软硬件设计中比较重要的部分,经测试,系统可实现对电子标签的读写、灭活等操作。并且在2dBi陶瓷天线的增益下,读写器识别距离较为理想。同时,设计基于LabVIEW的射频识别系统上位机,可以实现与下位机的数据通信、标签的EPC及RSSI等数据的可视化以及对读写器相关参数进行设置等功能。Aiming at the high cost and complicated production methods of the UHF RFID identification system popular in the current market,the design scheme of the UHF RFID reader compatible international standard ISO/IEC 18000-6C and EPC Class-1 Generation-2 protocol based on the RF read/write chip MagicRF M100 is proposed in this paper,and the working principle of the reader is elaborated in detail,and the more important parts of the system hardware and software design is introduced accordingly.The testing results show that the system can read,write and destroy the electronic tag.And under the gain of the 2dBi ceramic antenna,the reader recognizes the distance ideally.Meanwhile,the design of the radio frequency identification system host computer based on LabVIEW can realize the functions of data communication with the lower computer,visualization of data such as EPC and RSSI of the tag,and setting of parameters related to the reader.
