基于超宽带技术的矿用人员精准定位系统

提出一种基于超宽带技术的矿用人员精准定位系统，通过分析典型的SDS-TWR算法基本原理，利用矿井CAD图纸及二维坐标定位算法，首次实现了在CAD二维平面内对井下人员位置进行实时、动态、同步跟踪监测、高精度定位与轨迹回放综合管理。系统在莱芜矿业马庄铁矿进行了现场测试，实验结果表明，超宽带信号覆盖范围200 m内，系统对静态目标定位误差小于30 cm，动态目标在25 km/h移动速度下，定位误差小于1.65 m，满足煤矿井下对人员定位要求，具有广阔的市场推广前景及应用价值。

Precise positioning system for mine personnel basedon ultra wide band technology

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.
