Abstract

Abstract: Herein, a precise positioning system for mine personnel based on the ultra wide band (UWB) technology is proposed, and the basic principle of typical SDS-TWR algorithm is analyzed. Using mine CAD drawings and two-dimensional (2D) coordinate positioning algorithm, this is the first study to realize a comprehensive management system of real-time, dynamic, synchronous tracking and monitoring, high-precision positioning, and trajectory playback in a 2D-CAD plane. The system has been tested at the Mazhuang Iron Mine of Laiwu Mining. Experimental results show that within 200 m of the UWB signal coverage, the positioning error of the system with respect to a static target is less than 30 cm, and the positioning error of a dynamic target is less than 1.65 m with a moving speed of 25 km/h. The system meets the requirements of personnel positioning in coal mines and has a broad market potential and application values.

Key words: ultra wide band, mine personnel positioning;CAD two-dimensional plane
