In order to solve the problem of real-time accuracy location of substation staff and improve the intelligent security op-eration and maintenance level of substation,a substation staff positioning and tracking system based on particle filter Taylor al-gorithm is proposed.The hardware part of the proposed system consists of UWB base station,UWB tag,location computing server and related supporting facilities.The software algorithm optimizes the initial value of Taylor algorithm with the weighted least square method.After the preliminary positioning results are obtained,the particle filter algorithm is used to further smooth the location results,so as to realize the accurate positioning and tracking of personnel under the severe condition of non-line of sight(NLOS),and further improve the positioning accuracy.The application experiment results of the secondary switch room of Zhenjiang Yinshan 110 kV substation show that the personnel positioning and tracking system proposed in this paper can realize the personnel positioning with 10 cm accuracy under the severe condition of NLOS,which meets the practical appli-cation requirements,and has engineering practicability and feasibility.
