煤矿井下证人节点的精确定位技术研究

Research on Witness Nodes Precise Position Technology Underground Coal Mine

针对目前煤矿井下人员定位系统定位精度不高、存在定位盲区等问题,研究采用物联网辅助节点定位原理实现系统精确定位。本文分析了证人节点精确定位思想,设计了证人节点定位算法流程和具备行人航迹推算功能的定位系统,并选取楼道长直走廊模拟巷道环境进行了实验测试,验证了该方法的有效性。

In view of the current personnel positioning system in coal mine,the positioning accuracy is not high,and the location blind area exists.The research uses the principle of the Internet assisted node localization to realize the precise positioning of the system.In the paper, the idea of precise positioning of witness nodes is analyzed,the flow of witness node positioning algorithm and the positioning system with pedestrian track estimation function are designed.The test of the long lane corridor simulating the roadway environment is carried out to verify the effectiveness of the method.
