| 摘 要： | 标签防碰撞技术是RFID系统中的关键技术。该文在二进制算法的基础上,提出了一种改进算法。对碰撞位的表示方式进行了改进。读写器在检测到碰撞后,用一较短的包含碰撞位信息的定长序列来作为自己的命令参数;标签在接收到阅读器的请求指令后,发送位数低于碰撞位的序列号,减少了发送的数据量。改进后的算法很大程度上减少了搜索标签的时间。

| Abstract: | Anti-collision technique is a key technique in the RFID system.In this paper,an improved algorithm is proposed based on the binary algorithm.The representation method of the collision position is improved.When the reader detects the collision,it uses a shorter fixed-length sequence that contains the collision position information as its command parameters.The tags send the sequence that behind the collision position when they receive the command from reader.So the data that to be send is decreased.The impro... |
