摘要
针对北斗卫星定位技术因障碍物的阻挡导致室内无法获取定位信息的问题,提出了北斗室内外无缝定位技术方案。在此基础上,对卫星定位及超宽带(Ultra Wide Band,UWB)两种定位模式算法原理的研究,提出了一种可兼容两种定位模式的高精度定位算法,在该算法下可以实现两种定位模式的无缝切换,不影响最终定位结果精度。并对变电站等复杂电磁环境下的算法模型进行研究,确定了室内UWB定位基站的布站模式以及定位精度的实现方案,解决室内定位信号弱的难题,确保在实际应用环境中的定位精度。对电力系统中的人和设备的定位提供了理论依据。
Beidou satellite positioning technology has the problem that the indoor positioning information can not be obtained due to the obstruction of obstacles.A seamless positioning technology scheme of Beidou indoor and outdoor was put forward to solve this problem,basing on which the principle of satellite positioning and UWB positioning mode algorithm was studied,and a high⁃precision positioning algorithm compatible with the two positioning modes was proposed.In the algorithm,the seamless switching between the two positioning modes can be realized without affecting the final positioning accuracy.The algorithm model of substation and other complex electromagnetic environment was studied,and the layout mode of indoor UWB positioning base station and the implementation scheme of positioning accuracy were determined,which have solved the problem of weak indoor positioning signal,and ensure the positioning accuracy in practical application environment.This paper provides a theoretical basis for the positioning of people and equipment in power system.
