基于UWB（超宽带）技术并改进TDOA算法对矿下人员实时位置检测

ue to the complex working environment in mines, which often includes electromagnetic interference, radio frequency interference, geological and structural interference, mechanical and vibration interference, as well as environmental and human-related interference, conventional positioning methods cannot accurately and effectively track the real-time location of underground personnel. This paper proposes a real-time positioning system for underground personnel based on Ultra-Wideband (UWB). By deploying a network of UWB anchors and programmable tags, along with an improved Time Difference of Arrival (TDOA) algorithm, the system achieves centimeter-level positioning accuracy. Experimental tests demonstrate that, in underground multipath interference environments, the system achieves an average positioning error of ≤15 cm and a response latency of <200 ms, significantly improving emergency response efficiency and safety management standards.
