针对室内多种典型场景下UWB基站部署与定位精度间关系分析不够透彻的问题,该文研究了室内典型场景下不同数目和网型的UWB基站共面部署.基于基站密度建立部署性能分析模型,利用最小二乘、肖维勒准则及t检测实现动静态位置解算、数据预处理并进行精度评定,探究室内典型场景下合理的基站部署.选取4种场景(空旷房间、走廊、会议室和办公室)分别采用低密度三基站(三角型和L型)和四基站(菱型和方型)、高密度五基站(K型)和六基站(H型)开展实验.在空旷房间和其他3种场景下,定位精度最高的网型分别是低密度方型和高密度H型,平均绝对误差比其他网型至少减少了 26.92％、37.50％、17.24％和11.43％.室内典型场景下合理部署基站能够有效提高定位精度.
Research of UWB coplanar base station deployment in indoor typical scenarios
According to the problem that the relationship between UWB base station deployment and positioning accuracy is not thoroughly analyzed in a variety of indoor typical scenarios,this paper studied the coplanar deployment of UWB base stations with different numbers and types of network in indoor typical scenarios.Based on the density of base stations,a performance analysis model for deployment is established.,the dynamic and static position calculation,data preprocessing,and accuracy evaluation are achieved using the least squares,Shoveler's criterion,and t-detection to explore reasonable base station deployment in typical indoor scenarios.Four scenarios(open room,corridor,conference room and office)were selected to carry out experiments using low-density three base stations(Triangular-shape and L-shape)and four base stations(Diamond-shape and Square-shape),high-density five base stations(K-shape)and six-base stations(H-shape).In the open room and three other scenarios,the types of network with the highest positioning accuracy are low-density Square-shape and high-density H-shape,the mean absolute error has decreased by at least 26.92％,37.50％,17.24％,and 11.43％compared to other network types.Reasonable deployment of base stations in indoor typical scenarios can effectively improve positioning accuracy.
