改进的RFID防碰撞算法在仓储管理系统中的应用

Application of Improved Anti-collision Algorithm of RFID in Warehouse Management System

RFID标签防碰撞是无线射频识别技术的关键问题之一,目前常用的二进制防碰撞算法虽然识别正确率较高,但存在着重复搜索过程,影响了识别速度.为了提高RFID系统识别标签的效率,在二进制算法的基础上进行了改进,并对算法的性能进行了分析,得出改进的算法比二进制算法提高了识别的效率,尤其在被识别的标签数量较大时,能显著地节约识别标签所花的时间,提高仓储的作业效率.

RFID tag anti-collision is one of the key problems of radio frequency identification technology.Although the correct rate of binary anti-collision algorithm is higher,the repeat search process affects the recognition speed.To improve the efficiency of the RFID tag identification system,based on binary anti-collision algorithm have been made.In this paper,the performance of the improved algorithm was analysed.The results showed that compared with the binary algorithm,the improved algorithm could improve the efficiency of identification.Especially when the number of tags to be identified was large,the improved algorithm could save the time spent in identifying the labels significantly. Then the efficiency of warehouse operations was improved.
