Abstract: Provided are a method and system for detecting an oil abrasive particle size. The method includes: acquiring a voltage signal of an oil abrasive particle in real time, where the voltage signal is generated in real time in a process that the oil abrasive particle passes through an electromagnetic abrasive particle sensor; establishing a voltage curve coordinate system with an amplitude of the voltage signal as a Y-axis and a time of the voltage signal as an X-axis, and obtaining a voltage curve; performing feature extraction on the voltage curve, and obtaining an area S defined by a voltage curve within a half voltage signal cycle T and the X-axis and a maximum absolute value A of a voltage signal value according to the voltage curve coordinate system; and inputting S and A to a trained back propagation neural network for prediction to obtain a predicted oil abrasive particle size.
