基　　金：重庆工程职业技术院院级课题“基于LoRa的矿用精确定位系统设计与研究”(项目编号:KJA201803);国家重点基础研究发展计划(973计划)“煤矿动力灾害前兆采集传感与多网融合传输技术及方法”(项目编号:102405116)。

摘　　要：针对现有精确定位系统成本高、覆盖半径小和功耗大等缺点,设计了一种基于LoRa的矿用精确定位系统。该系统采用LoRa技术来获取人员标签与基站之间的距离数据,所设计的人员标签和基站具备电路结构精简、成本低廉、易于部署等优点。通过实测表明,在略微降低定位精度的条件下,采用LoRa技术的精确定位系统在覆盖半径、电池使用寿命以及设备成本等指标上,均优于采用CSS技术和UWB技术的精确定位系统。因此具备高性价比的LoRa矿用精确定位系统,能较好地促进精确定位系统在煤矿的推广应用。The present accurate positioning technology has the disadvantages of high cost,small coverage radius and large power consumption.An accurate positioning system based on LoRa for mine is designed.The system uses LoRa technology to obtain the distance information between the label and the base station,and the label and the base station have the advantages of simple circuit structure,portability and easy deployment.The actual measurement shows that LoRa technology can greatly reduce the power consumption and equipment cost of the accurate positioning system,and can expand the coverage distance of the accurate positioning system,although positioning accuracy is slightly reduced.
