An intelligent non-destructive inspection system of wire rope core conveyor belt is designed through the research of perspective and laser three-dimensional reconstruction technology, the failure characteristic detection and early warning of the inner and outer parts of the steel cord conveyor belt, the calculation of the frame selection area and the wear volume of the outer wear area, and the failure characteristic diagnosis of the steel cord such as the broken wire, tap, twist and the change of the length of the joint are verified by experiments, the results show that the system can accurately judge the fault point of the steel cord conveyor belt and give an early warning based on the analysis of the digital detection data of the belt.
