Multi-physics field fatigue intervention method and device

The invention discloses a multi-physics field fatigue intervention method and device. The method comprises the steps that human body electrocardiosignals are collected and preprocessed, and electrocardiosignals only containing electrocardiograph group wave information are obtained; extracting RR interval information from the electrocardiosignals only containing the electrocardiograph group wave information by adopting a self-adaptive threshold value method; extracting characteristic parameters of the RR interval information to obtain a characteristic parameter sequence; inputting the feature parameter sequence into a trained SVM multi-classification model to obtain a classification index; converting the grading index into a mode parameter; and determining an intervention mode according to the mode parameters, and performing fatigue intervention according to the intervention mode. According to the method, fatigue grades can be accurately and quickly divided, and different intervention means are realized accord
