首发时间:2018-05-03
Abstract:Aiming at the low accuracy of indoor position, this paper designed a novel indoor position system based on UWB. First, from the position accuracy, a cooperative position algorithm is proposed by analyzing and comparing the advantages and disadvantages of several position algorithms. And on the Matlab platform, the simulation model of the indoor position system is set up, and the position system is simulated with different distance error. The simulation results show that the position accuracy of the cooperative position algorithm is higher than the other two algorithms. Finally, based on the proposed position algorithm, this paper designs the hardware of the position system and experiments in the real indoor environment. The experimental results show that the position error of the proposed cooperative position algorithm is about 15cm, and the performance of the algorithm is better than the other two algorithms, and it can meet the normal indoor position requirements.

一种基于UWB的新颖室内定位系统
摘要:针对目前室内定位精度不高的问题,本文设计了一种基于UWB的新颖室内定位系统。首先通过分析对比几种定位算法的优缺点,从定位精度考虑,提出了一种协同定位算法。并在Matlab平台上,建立室内定位系统的仿真模型,分别在不同测距误差下对定位系统进行了仿真,仿真结果表明,协同定位算法的定位精度要高于其他两种算法。最后基于所提出的定位算法,本文对定位系统的硬件进行了设计,并且在真实的室内环境进行实验验证,实验结果表明,所提出的协同定位算法的定位精度为15cm左右,算法性能要优于其他两种,能满足正常的室内定位需求。
