摘　　要：在矿井人员准确定位的过程中,由于是通过粗略的信号定位估计来确定移动节点的位置信息,采用传统算法进行矿井人员定位,存在适应性差,定位精度不高。提出了一种采用Zigbee的矿井人员定位方法。根据接收信号强度初始判断井下人员与锚节点距离,运用最小二乘法对矿井人员方位进行估量,融合混沌粒子群方法对位置进行优化,利用动态三边测量(DTN)对移动节点进行详细的测距定位,最终实现了对矿井人员定位优化。实验结果表明,提出的基于Zigbee算法的矿井人员定位优化方法,精确度高,定位效率高,非常适合矿井人员定位。In the process of personnel＇s accurate positioning in mine, because the position information of the mobile node is determined by a rough signal position estimation, using the traditional algorithm for personnel positioning in mine, the adaptability is poor, and positioning accuracy is low. This paper proposed a method for personnel positioning in mine based on Zigbee. According to the received signal strength, the distance between personnel in mine and the anchor nodes can be initially judged. Using the least square method, the position of personnel in mine was estimated, and integrating chaos particle swarm algorithm was used to optimize the position. Dynamic three edge measurement （DTN） was used to measure the location of the mobile node in detail. Finally, the optimization of the personnel positioning in mine was realized. The experimental results show that the proposed optimization method has high precision and high efficiency of positioning, which is very suitable for the personnel positioning in mine.
