摘　　要：RFID技术中的防碰撞算法分为阅读器的防碰撞以及标签的防碰撞两种。文章通过对RFID中各种主流防碰撞方法的思想、实现及算法的研究,在现有的二进制搜索算法的基础之上,提出了一种改进算法,并对改进算法的实现进行了Matlab仿真。结果证实:改进后的算法相较其他算法在标签长度较短的情况下,可以表现出极其优越的性能。The anti-collision algorithm of RFID technology fails into reader anti-collision and tag anti-collision. Through the study of thoughts, implementation and algorithm of various mainstream anti-collision methods, an improved algorithm was put forward based on the existing binary search algorithm, and a simulation of the improved algorithm with Matlab is conducted. The results show that the improved algorithm has a very superior performance compared with other algorithms with short label length.
