摘要： 为了解决射频识别(RFID)系统中的多标签防碰撞问题，在分析帧时隙ALOHA算法的基础上，提出一种基于分组动态帧时隙的RFID防碰撞算法。当标签数量庞大时，该算法可以通过分组限制响应标签数量达到较高的识别效率。仿真结果表明，当标签数为1 000时，与传统算法相比，该算法能使时隙利用率提高80%以上。

Abstract: In order to solve the problem of collision between multi-tag in radio frequency identification(RFID) system. This paper proposes RFID anti-collision algorithm based on grouping dynamic frame slotted by analyzing frame slotted ALOHA algorithm. When there are a large number of tags in the field, it can achieve high discernment efficiency by grouping to restrict the number of response tags. Simulation results show that the algorithm improves the slot utilization rate above 80% comparing with the conventional algorithms, when the number of tag is 1 000.
