Method and device for detecting fatigue state of operator of nuclear power plant

The invention discloses a method and device for detecting the fatigue state of an operator of a nuclear power plant, and the method comprises the following steps: firstly, carrying out the random insertion of a reaction speed test for the operator of the nuclear power plant in each simulated nuclear power operation scene for all nuclear power operation scenes, physiological parameter data of the nuclear power plant operator and a test result made by the nuclear power plant operator for the reaction speed test are collected; preprocessing the physiological parameter data to generate a physiological signal sequence; determining a fatigue label corresponding to each section of physiological signal sequence by using a test result, and generating a fatigue physiological signal data set; inputting the fatigue physiological signal data set into a fatigue state detection model so as to train the fatigue state detection model; in a real nuclear power operation scene, collecting real physiological data of a nuclear pow
