摘要:
结合射频识别(RFID)系统的工作特点,在给出适用于该系统的面阵多波束实现方法基础上,提出了一种防冲突算法.该算法采用平面阵列天线,通过数字多波束形成算法控制加权系数,将三维空间划分为多个波束方向,并同已有基于时分多址(TDMA)算法相结合,实现对在阅读器的识别范围内大量密集分布的标签进行快速准确识别的目的.此外,在实现多标签识别的同时,该算法还引入二次波束形成策略,以解决波束之间的重叠碰撞问题.实验表明,本算法可将识别效率提高65%以上.
Abstract:
In this paper,a radio frequency identification(RFID) anticollision algorithm was proposed based on an analysis of digital multi-beaming forming algorithm of planar array antenna. For identifying the numerous dense tags quickly and accurately in the recognition range of reader,three-dimensional spaces were divided into several subspaces by using planar array antenna and combined with the existing time division multiple access (TDMA) algorithm to avoid the tag collision in each beam. Twice digital beamforming strategy was adopted to solve the reader collision in the overlapping areas between adjacent beams. The simulation results show that the efficiency of identification can be improved more than 65%.
