Method and related device for detecting state of psychological stress

Abstract

The embodiment of the present invention discloses a detection method and a related device of a state of psychological stress, the method comprising: collecting the electrocardiographic signal of the subject to be detected, and extracting the R wave in the electrocardiographic signal; obtaining the R wave in the electrocardiographic signal Multiple target RR intervals, based on multiple target RR intervals, the heart rate variability HRV time domain characteristic parameters, HRV frequency domain characteristic parameters and HRV nonlinear characteristic parameters are obtained; the heart rate variability HRV time domain characteristic parameters, HRV frequency domain characteristic parameters and The HRV nonlinear characteristic parameters are input into the stress detection model, and the psychological stress state of the subject to be detected is determined based on the stress detection model. By adopting the embodiment of the present invention, the psychological stress state of the subject to be tested can be detected based on the multi-dimensional parameters obtained from the electrocardiographic signal, and the accuracy and stability of the detection of the psychological stress state can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a detection method and a related device of a state of psychological stress. Background technique [0002] With the rapid development of economy and society, the psychological stress of the masses has become an important health problem in the world. Psychological stress is a psychological process triggered by external factors such as threats, injuries, or challenges. Greater psychological stress will affect health. [0003] At present, the evaluation of psychological stress status is often inseparable from the subjective opinions of experienced medical staff, and the common detection equipment of psychological stress status usually uses fixed indicators in Heart Rate Variability (HRV) to realize the detection of psychological stress status. Covering the vast majority of the population, while the detection accuracy of psychological stress state can not be guaranteed. [0004] T...
