摘要
针对煤矿井下人员定位困难以及现有定位算法存在较大定位误差的问题,提出了一种适合煤矿井下环境的新的热点簇中心定位算法。该算法利用RSSI值对移动节点在定位区域中的位置进行归类,有效地解决了现有文献定位方法中存在的定位盲点问题,同时,提高了定位的实时性能和定位精度。数值仿真和实验结果证明了本方法的有效性。
Considering the facts that the personnel orientation in the coal mine was difficult, and the existing algorithm is of high fixed position error, a new algorithm of hot spot cluster centered positioning for terrain underground in the coal mine was designed. The locations of moving nodes in position area were classified by using the RSSI, and the blind spots problems of positioning, which was not explained by the locating method mentioned in the existing literatures, was solved efficiently by means of new algorithm. Besides, the algorithm improved the real time performance and the accuracy of positioning. The validity of new algorithm was verified by the result of numerical simulation and experiment.
