The invention discloses a pilot fatigue detection method based on an electroencephalogram signal. The pilot fatigue detection method comprises the steps of based on wavelet packet preprocessing of theelectroencephalogram signal, four rhythm fatigue characteristic evaluation indexes of an electroencephalogram and a deep contraction self-encoding network, recognizing the pilot state and displayingthe recognized pilot fatigue state, firstly, utilizing a wavelet packet to preprocess the electroencephalogram signal and extracting four rhythm waves of the electroencephalogram signal; using a recombined wave band signal as a pure electroencephalogram and calculating fatigue characteristics based on power spectrum areas of the four rhythm waves; then utilizing an extracted deep contraction self-encoding network model to analyze the electroencephalogram signal to recognize the pilot state; displaying the recognized pilot fatigue state. The pilot fatigue detection method is used for airworthiness certification or recognition of the pilot fatigue state in high-altitude flight, the pilot fatigue state is monitored in real time, safe flight of a pilot is ensured, the pilot load is reasonablydesigned, and an airworthiness certification standard is completed.
