The invention discloses a driver mental fatigue recognition intervention method and system based on electroencephalogram signals, relates to the technical field of intelligent traffic, and solves the problem that fatigue recognition robustness is not high due to the fact that a fatigue recognition algorithm is easily interfered by the external environment. The method comprises the following steps: S1, preprocessing a physiological signal of a driver; s2, constructing a brain function network according to the preprocessed physiological signals; s3, electroencephalogram topological features are extracted from the brain function network; s4, inputting the electroencephalogram topological features into a recognition model, and recognizing the mental fatigue state of the driver by the recognition model according to the electroencephalogram topological features; s5, determining fatigue intervention measures according to the mental fatigue state of the driver; by analyzing the electroencephalogram signals, the system can detect the fatigue condition of the driver in real time.
