摘要
以基于射频收发芯片AS3992、工作于840～960 MHz UHF ISM频段的UHF RFID读写器核心模块作为硬件基础,在芯片已经集成18000-6C协议的基础上,软件上通过对码元进行曼彻斯特编码及CRC校验,从而实现读写器同时兼容18000-6B协议。分别合理配置防碰撞算法,18000-6C协议采用时隙ALOHA算法,18000-6B协议采用二进制搜索算法,使得该UHF RFID读写器能同时兼容读取大量18000-6B/6C电子标签。
The software systerm selected RFID UHF reader core modules as hardware foundation,working in 840-960MHz UHF ISM band,which based on the RF transceiver chip AS3992,integrated 18000-6C agreement on chip,and after Manchester coding and the CRC checking,RFID reader realized compatibly 18000-6B agreement in software.The paper allocated the anti-collision reasonably and respectively,18000-6 C used slotted ALOHA algorithm,18000-6B adopted binary search algorithm,which makes the UHF RFID reader is compatible with 18000-read 6B/6C electronic tags.
