An education experimental platform based on nondestructive testing of steel wire ropes is designed based on a research project and practical engineering problem. The steel wire rope is magnetized through the excitation mechanism, and the Hall sensor array is used to detect the radial magnetic field of the magnetized steel wire rope, then the signal processing technology is used to identify fault signature, and local flaw of the steel wire rope is finally recognized. This project involves a whole process of the signal through “generation—sensing—acquisition—transmission—recording—processing—application”, and forms a complete closed knowledge cycle. Thus, the students can understand the course knowledge system in an all-round way. It helps to stimulate students’ interest and cultivate students’ scientific research ability and innovation ability.
