Research and design of underground coal mine positioning technology based on signal distribution diagram construction

针对煤矿井下WiFi定位方式存在的定位精度不高的现状,提出了一种基于信号分布图构建的煤矿井下定位系统,分析了该定位系统的总体架构,介绍了该定位系统的硬件系统设计和软件系统设计,经过实际场景测试表明,采用信号分布图实现指纹定位算法可以满足煤矿井下定位精度的要求,能够有效解决现有煤矿井下定位系统精度差、部署复杂以及向新工作面扩展困难等问题。

In the view of the low accuracy of current WiFi positioning method in coal mine,underground coal mine positioning system based on signal distribution diagram construction was proposed,overall architecture of the positioning system was analyzed and the hard- ware and software system designs were introduced. The practical scenario test showed that the signal distribution diagram realized finger print positioning algorithm, which could meet the requirement of underground coal mine positioning accuracy and effectively solve the problems of low accuracy, complex deployment and difficult extension of current positioning system.
