摘　　要：提出一种用于矿井环境中人员及其他活动目标位置跟踪的定位算法,分析了将现有基于RSSI测距的定位算法应用到矿井环境存在的问题;针对矿井下的地形环境和信号传播特性设计了地图和信号参数的配置形式;详细描述了基于路径搜索的定位算法的实现。采用ZigBee技术构建本算法的实现平台,实验结果表明:算法定位准确、运算量小,适合矿井下的大规模部署。This article proposes a positioning algorithm for tracing personnel and other activities target location in coal mines, analyzes problems of using the current RSSI -based ranging positioning algorithm in mine environment. According to the particular structure of coal mine and signal propagation characteristics, this algorithm designs a specific configuration of map and signal parameters, and de- scribes the implementation of positioning algorithm based on path searching. The implementation platform of algorithm is constructed with ZigBee technology. Experiment results show that the algorithm is suitable for large - scale installation of mine with its higher accu- racy and small amount of computation.
