基于DV-hop算法的矿井人员定位系统研究

Research on Mine Personnel Positioning System Based on DV-hop Algorithm

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。

A wireless communication network project is put forward for the current low positioning accuracy of workers in coal mine by using ZigBee technology.It implements personnel positioning in coal mine with DV-hop Algorithm,meanwhile,sending position information to monitiong center by Multi-hop relay and cable network for inspetion and control in real time.Once there is a sudden accident,the monitoring center can locate the accurate position of workers in coal mine,and the positioning error is less than 15 meters,and also can take effective measures to rescue.
