基于惯性导航和Wi-Fi 6的矿井人员融合定位管控

Integrated Positioning Control of Mine Personnel Based on Inertial Navigation and Wi-Fi 6

针对井下人员定位精度差,搜救被困矿工人员困难的问题,研发了一套基于惯性导航定位和Wi-Fi 6中RSSI定位模型的融合定位信息系统。利用Wi-Fi 6的本地定位补偿,减少了惯性导航的实时全局定位误差。同时通过电子地图标注显示井下矿工的位置和行走轨迹,还可以利用地图信息的内部定位算法。管理人员能够实时了解矿山人员的动态和静态信息,有效提高矿山人员的位置管理和应急救援能力。

This paper focuses on the problem of poor positioning accuracy of underground personnel, and the difficulties in finding and rescuing trapped miners, aims to develop a set of fusion positioning information system based on inertial navigation positioning and RSSI positioning model in Wi-Fi 6. In this paper, by employing the local positioning compensation of Wi-Fi 6, the real-time global positioning error of inertial navigation is reduced. At the same time, the location and walking trajectory of the underground miners are displayed through the electronic map annotation, and the internal positioning algorithm of the map information can be used. Thus, the management person can grasp the dynamic and static information of mine personnel in real time, which effectively improves the position management and emergency rescue capabilities of the mine personnel.
