摘要
本文从RFID(Radio Frequency Identification,无线射频识别技术)的关键技术之一射频标签序号防碰撞入手,先介绍了常用的二进制防碰撞算法,针对其在终端射频卡数量越多,UID(Ubiquitous Identifications,身份识别标签)位数越多,传送时间越长的缺点;提出了二进制防碰撞算法的改进算法,改进算法与传统算法相比,在标签位数逐渐增多的情况下,其查询次数增加速度明显减慢;最后通过仿真给以证实。
In this paper, one of the key technologies of RFID radio-frequency tag numbers start with anti-collision,The first this paper introduced the common binary anti-collision algorithm, for the shortcomings of algorithm its terminal in the radio-frequency card, the more the card number and UID, the longer the transmission time;I proposed A binary anti-collision algorithm to improve the algorithm, the improved algorithm slow down in the pace of a gradual increase of label number than the traditional method;Lastly, through simulation to give confirmation.
