Abstract: The manual inspection work of the coal mine belt transportation system is strong, especially the inspection of the belt conveyor with a large slope is easily affected by coal falling, flying rocks, etc., which is dangerous. This paper designs the intelligent sensing and control system of a suspended inspection robot in coal mines, studies the overall architecture of the system and the layout of various sensors, and focuses on the functional design of the inspection robot's image acquisition, voice recognition, environment perception and wireless communication modules. And parameter optimization. Carried out field industrial tests in coal mines, effectively verifying the performance of the robot intelligent sensing and control system, which can realize the functions of meter data recognition, knob status recognition, belt deviation recognition, flame recognition, sound detection, abnormal alarm, etc., with coal mine transportation Comprehensive perception and real-time monitoring capabilities of the system status underground, above ground, and smart phone. Using inspection robots to replace people can realize continuous inspection operations in harsh environments such as underground high temperature, dust, and low illumination, effectively avoiding problems such as missed inspections and false inspections.
