摘要
井下巷道人员及设备定位是智慧矿山的重要功能,UWB定位系统依赖定位区域提前部署的大量锚节点,存在部署成本高的问题;针对上述问题,提出了巷道环境稀疏锚节点定位方法,以降低定位系统的部署成本;结合巷道特殊环境,设计了两点定位法获得标签节点的位置信息;设计了锚节点上安装双测距模块的锚节点的方法,获得两条不同的测距信息,提高了节点定位速率;提出了设置虚拟锚节点方法,将已定位的标签节点升级为虚拟锚节点,增加锚节点的密度,提高定位精度;最后的结果表明:该方法能够有效地降低锚节点的数量,减少人工部署的成本,提高节点的定位率。
Personnel and equipment positioning in underground roadway is an important function of smart mines.anultra wideband(UWB)positioning system relies on a large number of anchor nodes deployed in advance in positioning area,which has the problem of high deployment cost.Aimed at above problem,a localizationmethod forsparse anchor nodes for the roadway environment is proposed to reduce the deployment cost of the positioning system.Combined with the special environment of roadway,a two-point positioning method is designed to obtain the location information of label nodes.An anchor node with multiple ranging modules is designed to obtain multiple different ranging informationand improve node localization rate.A method of setting virtual anchor nodes is proposed,the located label nodesareupgradedto the virtual anchor nodes by the method,which increase the density of anchor nodes and improve the positioning accuracy.The final results show that the method can effectively reduce the number of the anchor nodes and improve the positioning accuracy.
