摘　　要：在矿井中进行节点定位时,由于矿井物理环境的复杂程度影响了节点定位的精确度,因此充分研究矿井的无线信号传播路径损耗模型,并在传统的质心算法中引进了加权质心算法,进而得出了新的无线定位改进算法。最后,经过MATLAB仿真表明,该算法提高了矿井中节点定位精度,由于仿真环境结合了实际矿井模型,具有普遍的矿井工程应用意义。The physical environment of underground mine is complication and worse, which has deeply influence on the precision of location, so the advanced wireless location method has been researched to improve the propagating loss model of mine,and combine with weighted centroid algorithm. The simulate result of MATLAB confirms that this method improves the accuracy of.location. Because the simulate results with MATLAB were made, combined with the actual conditions of mine enviroment, the method is meaningful to the operation in the mine production.
