摘要
在射频识别(Radio Frequency Identification,简称RFID)系统工作时,可能会有多个电子标签同时处于读写器的作用范围内,如果有两个或两个以上的电子标签同时向读写器发送数据,则会出现通信冲突或数据相互干扰。在读写器的接收器中,若不能正确识别电子标签的数据包,系统就会产生错误。为了防止RFID系统中多个电子标签同时向读写器发送识别信息产生冲突问题,从射频识别系统中防冲突算法的原理出发,研究了二进制搜索算法。结合动态二进制搜索算法的改进思路,提出了一种改良型动态二进制搜索算法。
When radio frequency identification system work, there may be more than one electronic tags at the same time in the role of the reader,if two or more of the RFID electronic tags at the same time transmit data to reader,there will be communication conflict, data interfere with each other.In the receiver of reader, the data packets of electronic tag can not be correctly identified and creat errors.In order to prevent from conflict while a number of electronic tags at the same time to transimt information to the reader to identify in the radio frequency identification （RFID）system,the paper set out to introduce the principle of the anti-collision algorithm of the radio frequency identification system and binary search algorithm are mainly specifically studied.With the improvement of thinking dynamic binary search algorithm,a modified dynamic binary search algorithm is proposed.
