【摘要】：针对现有煤矿井下精确人员定位系统采用大量有线通信线缆导致部署困难、成本高及紧急情况求援时智能化程度低等问题,设计了一种矿用智能精确人员定位系统。该系统中读卡器采用基于超宽带定位技术的到达时间测距方法准确获取人员标签位置,数据集中器通过LoRa无线通信技术收集读卡器采集的人员标签信息并上传至分站,地面监控中心根据分站上传的数据,在井下人员失去手动触发求救按钮能力时,通过紧急状况处理方案自动报警并通知管理人员。实测结果表明,该系统定位精度为1m,可在2km以内实现误码率小于5%的无线数据可靠传输,在井下人员失去手动触发求救按钮能力时自动报警率达93.5%以上。
[Abstract]:In order to solve the problems of difficult deployment, high cost and low intelligence in emergency situations caused by a large number of wire communication cables used in the present precise personnel positioning system in coal mine, a mine intelligent precise personnel positioning system is designed. In this system, the card reader uses the time-of-arrival ranging method based on the ultra-wideband positioning technology to accurately obtain the location of the personnel label, and the data concentrator collects the information of the personnel label collected by the card reader through LoRa wireless communication technology and uploads it to the sub-station. According to the data uploaded by the sub-station, the ground monitoring center automatically alarm and notify the manager through the emergency treatment scheme when the downhole personnel lose the ability to trigger the help button manually. The measured results show that the positioning accuracy of the system is 1 m, and the wireless data transmission with error rate less than 5% can be realized within 2km, and the automatic alarm rate is more than 93.5% when the downhole personnel lose the ability to trigger the help button manually.
