一种RFID阅读器的列表式读取方式研究

UID-listed reading mode of RFID reader

摘要:

为了提高RFID系统中阅读器的标签读取效率,提出了一种列表式读取方式．通过将阅读器内既定标签群体唯一识别号（UID）事先存储于阅读器地址列表中,按照一定规则对地址列表逐个锁定式搜索,完成标签识别．针对阅读器寻呼次数、传输时延以及系统效率等三个重要性能指标,对本算法进行仿真,仿真实验结果表明列表式读取方式较传统的二进制搜索算法性能更具优越性．

Abstract:

In order to improve the RFID system read efficiency, a reading mode named UID-Listed Reading Mode is proposed. With putting the UID of tags to be identified into the address list of a RFID reader, which was formed in advance, the address list would be tracked and searched until all of the tags were identified one by one, according to certain rules. To prove the strong points of the UID-Listed reading mode proposed, query times, transmission delay and system efficiency were simulated, and then contrasted with the Binary Search Algorithm, which had similar operation principle with proposed reading mode. The consequences of simulation indicate that the UID-Listed reading mode turns out to be better than the classical binary search algorithm.
