Abstract: Aiming at problems of poor information perception ability and low decision level in coal mine safety production, a coal mine information comprehensive perception and intelligent decision system was proposed, which was composed of capsule network layer, data transmission layer and cloud service layer. The capsule network layer is composed of personnel position and behavior perception capsule, equipment status perception capsule and environment perception capsule to realize comprehensive perception of "person, machine and ring" in coal mine. The data transmission layer adopts method of combining wireless sensor network and wired network to realize reliable data transmission in underground coal mine. The cloud service layer provides guarantee for efficient and reliable decision for coal mine production through intelligent decision mechanism based on random forest. The experimental results verify effectiveness of the system.
