摘要
在煤矿开采过程中,通过应用井下人员定位系统,可以有效提高矿井的安全性。基于此,首先阐述了超宽带UWB技术(无载波通信技术)及人员定位的基本原理,然后对定位系统框架进行了分析,该系统主要由井下、地面两部分构成,前者负责采集人员标签信息,后者借助内置算法对标签坐标进行计算;其次,对人员标签和定位基站的硬件结构及设置进行了研究,两者硬件结构接近,主控芯片与无线信号收发芯片分别为STM 32、DW 1000;最后,对该系统的运行效果进行了试验,结果显示人员的定位误差小于1 m,有利于提高井下人员作业的安全性。
In the process of coal mining,the application of underground personnel positioning system can effectively improve the safety of the mine.Based on this,the basic principles of UWB technology(carrier free communication technology)and personnel positioning were first explained.Then,the framework of the positioning system was analyzed,which mainly consists of underground and ground parts.The former is responsible for collecting personnel tag information,while the latter uses internal algorithms to calculate tag coordinates.Secondly,the hardware structure and settings of personnel tags and positioning base stations were studied.The hardware structures of the two are similar,with the main control chip and wireless signal transceiver chip being STM 32 and DW 1000,respectively.Finally,experiments were conducted on the operational effectiveness of the system,and the results showed that the positioning error of personnel was less than 1 m,which is beneficial for improving the safety of underground personnel operations.
