Research on A Low-power Underground Personnel Positioning and Tracking System Based on Bluetooth 4.0

为解决矿山井下人员多种定位跟踪系统普遍存在的高复杂度、定位精度低、续航能力差等问题,提出一种基于蓝牙4.0的低功耗井下人员定位跟踪系统,并对该定位跟踪系统的定位跟踪算法以及系统软硬件进行了研究分析,提出了该系统的软硬件设计以及定位跟踪算法的实现方法,并通过仿真模拟对该系统方案进行了检验,结果表明:基于蓝牙4.0的低功耗井下人员定位跟踪系统的跟踪误差为0.26,且具有易于部署、定位准确、功耗低等优势,为矿山井下人员定位提供了新方案。

In order to solve the existing problems of personnel positioning and tracking system in mines, such as high complexi- ty, low positioning accuracy and poor endurance, a low-power underground personnel positioning and tracking system based on Bluetooth 4.0 was proposed. And the positioning and tracking algorithm of the system were analyzed, as well as its hardware and software. Then, the hardware and software designs and the implementation method of positioning and tracking algorithm were put forward and the system scheme was verified by analogue simulation. And the results showed that, the tracking error of the system was 0.26, and the new system had advantages of flexible arrangement, accurate positioning, and low power consumption and so on, which provided a new solution for personnel positioning and tracking in underground mines.
