摘　　要：针对煤矿井巷复杂作业环境导致的人、机、物定位和跟踪精度差问题,基于Wi-Fi指纹设计了接收信号强度指示(RSSI)区域定位和信道状态信息(CSI)精确定位相结合的煤矿井巷目标追踪实验,实验融合了通信、数字信号处理和现代信号处理等学科知识。构建了煤矿井巷目标定位追踪系统模型,并提出了基于煤矿井巷信号接入点(AP)测量准确度的动态在线匹配(ABAPM)RSSI区域定位和基于稳定载波链路的环境修正(EMSCL)CSI精确定位算法。实验结果表明,基于煤矿井巷信号接入点测量准确度和可信载波链路的有效判断,提出的ABAPM与EMSCL联合定位算法较好地解决了煤矿井巷中存在的信号接入点被移动物体遮挡、载波链路不稳定、离线环境与在线环境变化等问题,与传统RSSI与CSI算法相比,联合定位算法定位与追踪效果更佳。Aiming at the challenge of poor accuracy in human,machine,and object positioning and tracking caused by the complex working environment in coal mines,a coal mine tunnel target tracking experiment is designed based on Wi-Fi,which combines received signal strength indicator(RSSI)area positioning and channel state information(CSI)precise positioning.The experiment integrates the knowledge of communication,digital signal processing and modern signal processing,and constructs the target positioning and tracking system model of coal mine roadway.An accuracy base on access point measurement(ABAPM)RSSI regional positioning algorithm based on the measurement accuracy of coal mine roadway signal access point and an environment modified based on stable carrier link(EMSCL)CSI precise positioning algorithm are proposed.The experimental results show that the proposed ABAPM and EMSCL joint algorithm can effectively judge the accuracy of the signal access point(AP)and the credible carrier link in the coal mine roadway,and solve the problems of AP occlusion by moving objects,unstable carrier link,offline environment and online environment changes in the coal mine roadway.Compared with the traditional RSSI and CSI algorithms,the positioning and tracking effect is better.
