Multi-channel signal fusion method for magnetic leakage detection of steel wire ropes

This paper analyzed some problems in the existing magnetic leakage detection system of steel wire ropes, such as the small amplitude of the damage signal and the relatively simple processing method of multiple magnetic sensitive components at the front end, and in response to these problems, a multi-channel signal fusion method in the magnetic leakage detection system of steel wire ropes was proposed. First, from the perspective of magnetic sensor arrays, a variety of magnetic sensor array methods were proposed. Secondly, from the perspective of signal processing analog circuits, a multi-channel signal fusion hardware circuit was designed. Finally, actual tests were conducted on steel wire ropes to verify the feasibility of this method.
