基于WSN的多金属矿井下人机定位系统设计

Design of Personnel and Vehicle Positioning System in Polymetallic Mine Based on WSN

综合运用超宽带通信(UWB)、高速工业以太网络、井下高精度地图及计算机三维展示技术,构建了多金属矿井下人员及车辆无线传感器网络定位系统。系统结合到达时间法(TOA)和卡尔曼滤波,实现了固定基站节点和移动传感器节点之间的精确测距;利用无线传感器网络定位模型,实现了井下人员和车辆位置信息的实时感知。系统可以实时掌握井下人员及车辆的时空分布,监控人员及车辆的运动轨迹,具有系统部署灵活、响应速度快、鲁棒性好的特点。

A wireless sensor network positioning system for underground personnel and vehicles in polymetallic mines is constructed by using ultra-wideband communication(UWB),high-speed industrial Ethernet,underground high-precision maps and computer three-dimensional display technology.The system combines time of arrival method(TOA)and Kalman filter to achieve accurate ranging between fixed base station nodes and mobile sensor nodes.The real-time perception of underground personnel and vehicle location information is realized by using wireless sensor network positioning model.The system can grasp the spatial and temporal distribution of underground personnel and vehicles in real time,and monitor the trajectory of personnel and vehicles.It has the characteristics of flexible system deployment,fast response speed and good robustness.
