To ensure the safety of belt transportation, the corridor needs to be inspected and the accumulated coal needs to be cleaned regularly. Currently, inspection robots are usually used for monitoring, so that the fault location of the coal conveyor belt can be discovered in time, facilitating its timely inspection and maintenance.
