针对目前矿井内部工作人员定位精度低的难题,提出了利用ZigBee技术组建井下无线通信网络的方案,通过采用距离向量-跳段DV-hop算法实现井下人员定位,同时将位置信息通过多跳中继和有线网络方式发送到地面监控服务中心,以实现实时监视和控制。一旦发生突发事件,可通过监控中心对井下人员进行精确定位,定位误差小于15 m,并能够及时采取有效措施展开救援。 Aimed at the problem of low positioning accuracy of internal staff in mine, a scheme of using ZigBee technology to establish underground wireless communication network was proposed. Through the use of distance vector - hop-segment DV-hop algorithm to realize underground personnel positioning, at the same time, the location information was transmitted through multi-hop relay And wired network sent to the ground monitoring service center in order to achieve real-time monitoring and control. Once an emergency occurs, the downhole personnel can be precisely positioned through the monitoring center with a positioning error of less than 15 m and timely and effective measures can be taken to rescue the mine.
