摘要
针对矿井下人员定位困难以及巷道内部结构复杂寻路难的问题,提出了一种基于iBeacon设备的矿井下人员定位与导航系统。该系统具备对井下人员的实时定位,矿井下环境数据的实时监测,基于矿井真实结构的路径规划与导航,危险预警功能。设计了系统架构,介绍了系统的硬件设计与软件设计以及详细分析了定位与导航算法,通过实验验证了系统的实用性与可行性。实验结果表明,该定位与导航系统的定位精度低于1.5m,且比较于传统的A*算法提升24%的搜索效率。
In view of problem that mine personnel positioning and the problem of finding the road with complex internal structure of the mine,this paper presents a mine personnel positioning and navigation system based on iBeacon equipment.The system has the functions of real-time positioning of mine personnel,real-time monitoring of underground environmental data,path planning and navigation based on the real structure of the mine and danger warning.In this paper,I introduced the system architecture,hardware design and software design of the system and analyzed the positioning and navigation algorithms in detail.The practicability and feasibility of the system are verified by experiments.The experimental results show that the positioning accuracy of the positioning and navigation system is less than 1.5m,and the search efficiency is improved by 24%compared with the traditional A-Star algorithm.
