摘　　要：在超高频段,ISO/IEC 18000-6标准中6B多用于交通领域,而6C主要用于物流、生产管理和供应链管理领域。分析了ISO/IEC 18000-6 C标准,基于此标准设计了一种超高频射频识别读写器。详细阐述了读写器的软硬件设计,其中硬件设计主要包括射频发送电路、射频接收电路和数字基带处理电路。读写器软件设计中叙述了整体设计结构、基于概率、槽计数器的防冲突算法、发送接收链路的数据编解码设计、16 bit CRC校验以及读写器对标签操作命令流程。ISO/IEC 18000-6B has been mainly used in traffic while ISO/IEC 18000-6C has been mainly used in logistics, production and supply chain management.The ISO/IEC 18000-6C protocol standard, and designed an UHF RFID interrogator based on the standard are. Both software and hardware of the design are discussed. The hardware includes the RF sending cirouit, the RF receiving circuit and the digital base band processor circuit. The software includes the functioning mechanism, anti-collision algorithm and implementation of decoder elaborated explicitly.
