摘要
在分析EPCglobal UHF class1 generation2和基于DFSA协议的高速标签识别算法的基础上,采用位隙FSA协议标签响应标志位隙的设置方法,通过在标签上设置一个组位隙响应标志字,提出了一种EPC Gen2标准下的RFID标签分组多位隙并行识别协议GMBPIP,设计了一条新的分组查询命令和基于DFSA的多组标签并行识别协议流程,从理论上了分析GMBPIP协议的性能,并使用EPC Gen2标准协议时间参数进行了仿真实验。结果表明,GMBPIP协议在不增加标签太多计算负担的情况下,能够在EPC Gen2标准下有效降低时隙空闲率和冲突率,提高了标签的识别率、时隙利用率;平均识别率不仅突破了帧时隙ALOHA协议最高36. 8%的瓶颈,而且高于目前文献所述同类算法的性能指标,达到了70. 95%~81. 61%。GMBPIP可以作为低成本RFID系统高速识别大量被动标签的支撑协议。
