Research on UWB personnel positioning system in coal mine

  • 摘要: 针对煤矿井下复杂环境中非视距(NLOS)干扰影响无线信号传输问题,设计了一种煤矿井下超宽带(UWB)人员定位系统。该系统采用带有回传帧机制的非对称双边双向测距算法进行测距,无需时钟同步,保证了测距精度;采用区域判定策略和区域校正策略划分定位区域,使得标签只与自身所在定位区域内基站通信实现定位,避免了定位过程中的大量无效帧问题,提高了定位效率;采用加权最小二乘法与无损卡尔曼滤波联合定位算法解算标签位置坐标,提高了定位精度;在基站中配置了备用电源,保证在断电情况下的应急供电;采用以太网与LoRa 2种通信方式,在以太网断线情况下以LoRa方式传输测距数据,保证了系统应急通信。测试结果表明:该系统具有较高的动静态定位精度,抗NLOS干扰能力较强;在基站断电或以太网断线情况下,系统能够实现一段时间内的应急通信。
