The invention discloses a method for constructing a mental fatigue detection data set based on a PVT experimental normal form, which comprises the following steps of: inducing mental fatigue of a subject by using the PVT experimental normal form, and synchronously acquiring behavioral performance and corresponding electroencephalogram signal data of the subject; performing noise reduction preprocessing on the collected electroencephalogram signals; segmenting fixed-length segments corresponding to the test times from the electroencephalogram signals; based on the reaction time task performance indexes of the PVT, various derived task performance indexes are formulated, and the task performance indexes and the combination thereof are used for representing the mental fatigue state; based on the task performance indexes and the mental fatigue state represented by the task performance indexes, a classification threshold value, a classification benchmark and a cleaning method are set, and the electroencephalogram
