摘　　要：针对煤矿环境复杂、易发生信号丢失致使井下作业人员定位结果存在较大误差的问题,提出煤矿环境下人员的移动无线传感器节点协同定位算法。采用min-max算法构建网络节点的锚盒,确定井下人员移动范围,并利用MBTA算法得出各样本间距离;使用未知节点历史时间点空间位置信息,将未知节点历史时间点空间位置作为锚节点空间位置,完成煤矿人员的协同定位。结果表明:本文方法定位误差较小,适用于复杂煤矿环境下人员定位。The positioning error of underground operation personnel is large,resulting in the loss of signal and other problems.Based on this,a cooperative localization algorithm of mobile wireless sensor nodes for personnel in coal mine environment is proposed.The min-max algorithm is used to construct the anchor box of the network node to determine the movement range of underground personnel,and the MBTA algorithm is used to obtain the distance between each sample;Using the spatial position information of the historical time point of the unknown node,the spatial position of the historical time point of the unknown node is used as the spatial position of the anchor node to complete the collaborative positioning of coal mine personnel.The results show that the proposed method has small positioning error and is suitable for personnel positioning in complex coal mine environment.
