一种多标签移动环境下的RFID防碰撞算法

Evaluation of RFID collision algorithm in mobile-tags environment

分析了智能超市结算口处安装RFID自动支付系统中多标签移动场景对标签可靠识别的应用要求.改进了现有的标签防碰撞算法来提高标签识别效率、减少识别时间.该算法通过删除EPC码版本号、倒置编码顺序、标签预估计等策略,实现对商品标签的快速识别.通过仿真证明了该算法具有识别效率高等优点.

This paper analyzed the application requirements of the reliability identification in multi-tags mobile environment,which has been installed an RFID self-payment system in the smart supermarket export.To increase the tag identification efficiency and reduce the recognition time,it was necessary to improve the existing anti-collision algorithm.This algorithm has achieved quickly identification of products by removing the EPC code version number,reversing coding order,tags pre-estimation strategies and so on.The simulation results proved that the algorithm has a high identified efficiency
