摘　　要：针对煤矿井下无线信道的信号传播模型,提出将接收信号强度复合滤波器、一元线性回归测距模型和多边定位方法相结合的改进接收信号强度指示(Received Signal Strength Indicator,RSSI)值的井下定位技术,通过利用基于无线传感器网络操作系统TinyOS的节点进行离线建模、在线测算,实现煤矿井下人员及设备的实时定位。井下巷道试验表明,该技术提高了定位精度,增强了定位系统的鲁棒性,适用于煤矿井下定位。An improved Received Signal Strength Indication（RSSI） value localization technology which combined the Received Signal Strength Indication multiple filter,the linear regression distance measurement model and the multilateral location method for miners and equipment was proposed according to the signal transmission model of underground radio channels in this paper,and by using the nodes which were based on the wireless sensor network system TinyOS,an off-line model was built and the on-line calculation was conducted,this thus realized the real-time location of underground miners and equipment.The tests in mine roadways showed that this technology improved the location accuracy,enhanced the system＇s robust and can be used for underground location.
