Detection method and related device of psychological stress states

Abstract

Embodiments of the present invention disclose a detection method and a related device of psychological stress states. The method comprises the following steps: collecting electrocardiosignals of subjects to be detected and extracting R waves in the electrocardiosignals; acquiring multiple target RR intervals of the R waves in the electrocardiosignals, and acquiring heart rate variability (HRV) time domain feature parameters, HRV frequency domain feature parameters and HRV nonlinear feature parameters based on the multiple target RR intervals; and inputting the heart rate variability (HRV) time domain feature parameters, HRV frequency domain feature parameters and HRV nonlinear feature parameters into a pressure detection model, and determining the psychological stress states of the subjects to be detected based on the pressure detection model. According to the embodiments, multi-dimensional parameters obtained from the electrocardiosignals can be used to detect the psychological stress states of the subjects, and detection accuracy and stability of the psychological stress states 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...
