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
Real-time location detection of personnel underground based on UWB (Ultra-Wideband) technology and improved TDOA algorithm
摘要
矿下工作环境复杂，常存在电磁干扰、无线电频率干扰、地质与结构干扰、机械与振动干扰、环境干扰和人为干扰等，导致常规定位方法无法准确有效地定位矿下人员的实时位置。本文提出基于UWB对矿下人员实时定位系统通过部署UWB锚点网络与编写式标签，改进的TDOA（到达时间差）算法实现厘米级定位。实验测试表明，该系统在井下多径干扰环境下平均定位误差≤15cm，响应延迟<200ms,显著提升了应急响应效率与安全管理水平。
Abstract
Due 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.关键词
