基于UWB的矿井人员精准定位技术

摘要

A design and implementation scheme of mine personnel precise positioning system based on UWB technology was proposed. The principle of SDS -TWR ranging algorithm is analyzed. Combining with the one -dimensional linear space characteristics of mine roadway, the system uses a single card reader to achieve precise positioning and direction discrimination, and uses time division multiplexing technology to solve the wireless signal collision problem and the method ensures the positioning success rate and improves the positioning accuracy. The experimental results show that the positioning accuracy of the system is less than 0.3 meter and the effective coverage reaches 300 meters, which meets the actual needs of mining.%提出了一种基于UWB技术的矿井人员精准定位系统的设计与实现方案.分析了SDS-TWR测距算法原理,结合矿井巷道一维线性空间特征,采用单个读卡器实现精准定位和方向判别,并且采用时分复用技术解决无线信号碰撞问题,保证了定位成功率,提高了定位精度.试验结果表明:该系统定位精度达到了0.3 m以内,有效覆盖范围达到300 m,满足矿用实际需求.
