摘要
射频识别技术应用前景广泛,技术标准以ISO/IEC为主。与传统通信系统一样,RFID系统也存在信道争用问题——标签冲突问题,标签防冲突性能是决定RFID系统性能的关键参数之一。论文比较研究了ISO/IEC标准体系里关于高频13.56MHz频段的几个协议的标签防冲突算法,分析了各自特点,并对技术改进方向提出了一些看法。
RFID has been popular for a long time, and plays an important role in industry and trade. Protocols of ISO/ IEC are valued worldwide. Like traditional communication system, anti-collision is a problem of RF1D, which is a key efficiency factor. The paper analyzes and compares anti-collision algorithms of three ISO/IEC protocols about high-frequency（13.56MHz） RFID system.
