摘要

With the continuous expansion of power grid companies' production scale, it is of great significance to develop wearable devices that are suitable for on-site power operations in order to increase inspection efficiency, improve safety management levels, and improve emergency treatment levels. Among them, the precise positioning of wearable devices is a key part of the research. In view of this, this paper analyzes the precise positioning requirements of wearable devices in power job scenes, combines GPS and UWB positioning principles and their positioning characteristics, determines the GPS/UWB combined positioning mathematical model, and proposes using Helmert variance component estimation to estimate the combination. System view measurement is reasonable and right, GPS and UWB positioning are integrated with each other, and the seamless positioning task of power field operation wearable device is completed.
