摘要
为了能够在低成本的RFID单片机上运行碰撞标签数的估计算法,需要降低RFID盘存标签数的计算复杂度。本文推导分析了在总时隙长度足够大的前提下,碰撞标签的数量主要取决于碰撞时隙占比,与空闲时隙占比或单标签时隙占比的相关性较小。通过对比分析表明,在对精度要求不高的情况下,计算碰撞标签所依赖的变量维度可以从3维下降到1维,从而简化盘存标签数的计算。
In order to run the algorithm of estimating collision tag count on a low-cost RFID MCU,it is necessary to reduce the computational complexity of RFID inventory tag count.In this paper,it is deduced that under the premise that the total time slot length is large enough,the number of collision labels mainly depends on the proportion of collision time slots,and the correlation with the proportion of idle time slots or the proportion of single label time slots is small.Through comparative analysis,it is shown that in the case of a low precision requirement,the variable dimension on which the collision label is calculated can be reduced from 3 dimensions to 1 dimension,thereby the calculation of inventory tag count is simplified.
