摘　　要：阐述一种基于UWB的多基站高效DS-TWR测距算法。通过测距消息帧的时分控制(TDMA)来减少测距消息帧的数量,用基站对标签的时隙控制来自动分配各标签的测距时间点,使标签有序工作。实验结果表明,该测距方法具有标签功耗低、标签容量大、测距时延小、系统响应快等特点。This paper explains an efficient DS-TWR ranging algorithm based on UWB for multiple base stations.It reduces the number of ranging message frames through time-division control(TDMA)of ranging message frames,and automatically assigns ranging time points to each tag through time slot control of the base station,so that the tags work in an orderly manner.The experimental results show that this ranging method has the characteristics of low tag power consumption,large tag capacity,small ranging delay,and fast system response.
