Experimental Design of Coal Mine Tunnel Target Tracking Based on Signal Strength and Channel State
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.
