摘要
为了降低扫描次数和摆脱定位对RSSI值的依赖,提出了一种快速收敛的RFID标签定位算法。通过手持RFID阅读器扫描目标,以读写边界的交点求得目标定位点,并结合组合数学求出满足定位点的解集,以均值优化得到精确定位坐标。实验结果表明,该算法呈现了快速的收敛性,且定位误差低至8cm。
In order to reduce the number of scan,and do not use the RSSI value,a rapid convergent RFID localization algorithm is proposed.It scans the target tag with a handheld RFID reader.The target locating point can be obtained by the intersection of the reader＇s reading boundary.The algorithm combines the combination mathematics to find all the solutions of the fixed point,and average optimization is used to get accurate positioning coordinate.The experimental results show that this algorithm converges fast,and the positioning error is as low as 8cm.
