摘要
主要对RFID的标签防碰撞算法进行研究,RFID系统中的二进制防碰撞算法的原理和二进制搜索算法,并在此基础上提出改进的算法。介绍改进的二进制算法需要的编码方式和指令、算法的基本原理并且举例说明算法的工作流程。从阅读器的通信次数、传输时延和吞吐量三个方面,仿真并分析改进的二进制算法,仿真结果与分析表明改进的二进制算法的性能高于二进制搜索算法。
The research on anti-collision algorithm for the label of RFID was carried out in this paper.The theory of binary anti-collision algorithm and binary search algorithm in RFID system were introduced,based on which,the improvement of the algorithm was proposed.The encoder mode needed by the binary algorithm together with the basic principles of instruction and algorithm were all introduced,and the workflow of the algorithm was explained through example.From three aspects of the communication frequency,transmission delay and throughput of the reader,the improved binary algorithm was simulated and analyzed.The results show that the performance of the improved algorithm is higher than that of binary search algorithm.
