摘　　要：对已有的防冲突算法进行分析比较,从通信过程的数据量和搜索命令的发送次数这两方面考虑,提出了一种基于RFID的改进二进制防冲突算法,运用FPGA器件对其进行仿真,验证了该优化算法在性能上有较大提升。多标签识别防碰撞技术是射频识别RFID应用研究中的关键技术之一,主要包括基于时隙的ALOHA统计型算法及基于二进制的搜索确定型算法。The existing anti-collision algorithm was analyzed and compared in this paper. Considering that the number of the amount of data sent from the communication process and the search command, it pro- posed an improved binary anti-collision algorithm based on RFID, and using FPGA device to simulate the implementation, validation of the optimization algorithm has great improvement in performance. Multiple tag identification anti-collision technology is one of the key technologies of radio frequency identification application, including of ALOHA statistical algorithm based on time slot and deterministic algorithm based on binary search.
