The invention belongs to the technical field of rail transit turnout fault diagnosis, and particularly relates to a railway turnout fault diagnosis method and system based on machine learning, and the method comprises the steps: sampling a power characteristic curve of a switch machine for multiple times, carrying out the normalization processing and analysis of the collected power characteristic curve, and obtaining a power characteristic curve of the switch machine; the method comprises the following steps: acquiring power characteristic curve slope data of the action of the switch machine in each process, and calculating the power characteristic curve slope data of the action of the switch machine based on the power characteristic curve mean value slope data; training set data and test set data are selected according to the concentration degree of power characteristic curve mean slope data to train and test the deep belief network model DBN, and power curves corresponding to various actions in different processes when the switch machine works in real time are input into the trained deep belief network model DBN. The deep belief network model DBN carries out comparative analysis on the slope of the real-time power characteristic curve of the switch machine, and whether the switch machine breaks down or not and the fault type are judged.
