摘要: 针对库位管理中常用的 LANDMARC 定位算法在参考标签的选择和信号损耗误差方面存在的问题,提出了改进的 LANDMARC 定位算法,在不增加参考标签数量的前提下,找到与待定位标签距离最近的参考标签,并通过“距离- 损耗”公式,得到精确定位计算的方法。结果表明该改进算法提高了定位的精度和收敛速度。

Abstract: Aiming at the problem of Location Identification based on dynamic active RFID calibration ( LANDMARC) location algorithm on the choice of reference tags and loss of signal error, which monly used in inventory management, this paper put forward an improved LANDMARC location algorithm, which found the nearest undetermined reference tags wihtout increasing the number of reference tags, and got the precise location calculation method by the distance-loss formula. The result shows that the improved algorithm can improve the location precision and convergence speed.
Key words: inventory management; location; Location Identification based on dynamic active RFID calibration ( LANDMARC)
