The embodiment of the invention provides a turnout jamming diagnosis method and device based on a current curve and electronic equipment. The method comprises the following steps: acquiring current data of a point switch; performing wavelet transformation on the current data and generating a sampling current curve; performing noise reduction processing on the sampling current curve by using accumulative integral; performing high-pass filtering processing on the sampling current curve after noise reduction processing, and generating a corresponding filtering current curve; performing curve segmentation on the filtering current curve by using a KS density function method, and screening out a target data section; performing linear fitting on the data in the target data section; and judging whether the turnout is jammed or not according to a linear fitting result. In this way, feature recognition of the current curve can be completed with high quality and high efficiency, and it is ensured that whether the turnout is jammed or not is diagnosed timely and accurately.
