摘要
煤矿井下环境复杂,往往在出现安全事故时会导致救援非常困难。基于RFID技术的井下人员定位误差较大,使用UWB无线传感网络可以有效提升井下人员定位精度。对UWB无线传感网络的测距原理进行了阐述,并对井下UWB信号衰减原因进行分析,构建了基于UWB技术的井下无线传感网络,并提出了基于ARM+DW1000的硬件设计方案。对UWB无线传感网络进行静态测试、动态测试、跟踪测试,测试结果表明UWB无线传感网络精度较高,完全满足井下人员定位需求。
The underground environment of coal mine is complicated,and the rescue is very difficult when safety accidents occur.The positioning error of underground personnel based on RFID technology is large,and the use of UWB wireless sensor network can effectively improve the positioning accuracy of underground personnel.The ranging principle of UWB wireless sensor network is described,and the reason of UWB signal attenuation is analyzed.The underground wireless sensor network based on UWB technology is constructed,and the hardware design scheme based on ARM+DW1000 is proposed.The static test,dynamic test and tracking test of the UWB wireless sensor network are carried out.The test results show that the UWB wireless sensor network has high accuracy and fully meets the positioning requirements of underground personnel.
