Psychological stress monitoring method and device based on fusion of pulse rate variability and sleep quality

Abstract

The invention discloses a psychological pressure monitoring method and device integrating pulse rate variability and sleep quality. The method comprises the following steps of firstly collecting humanphotoplethysmography pulse signals and acceleration signals to recognize the current motion state; if the recognition result is a motion, discarding the pulse signal data, and if the recognition result is a peace state, first preprocessing the photoplethysmography pulse signals, then, extracting feature parameters of the pre-processed pulse signals to extract multidimensional feature parameters which can be used for measuring human psychological pressure, then inputting the extracted features into a pre-trained classifier, outputting the pressure state index, and finally, combining with recent sleep quality, and assisting the classifier to get the final psychological pressure state. The method and device can reduce the cost and complexity of pressure monitoring, can solve the problem of insufficient characterization ability of feature parameters of a single physiological signal, and at the same time, can greatly reduce the false judgment probability brought by short-range monitoring and ensure the accuracy and feasibility of the psychological pressure monitoring.

Description

technical field [0001] The invention belongs to the technical field of mental health applications, and in particular relates to a psychological pressure monitoring method and device combining pulse rate variability and sleep quality. Background technique [0002] Psychologists point out that 15%-20% of the general population has emotional disorders and psychological distress. In fact, it is often seen in real life that the onset of many patients is related to emotional agitation and excessive stress. Therefore, in people's study and life, it is very important to recognize their stress state in a timely and correct manner. [0003] For the recognition of one's own psychological pressure, the traditional method of using psychological scales to evaluate the pressure generally requires the cooperation of professional testers and the correct cognition of the testee to make an accurate assessment. The actual operation is inconvenient and the assessment is subjective. strong. Ob...

Problems solved by technology

[0007] An object of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a psychological stress monitoring method that combines pulse rate variability and sleep quality. Variability and sleep quality are integrated to jointly determine the state of human stress, which solves the shortcomings of using a single physiological signal and can greatly reduce the probability of misjudgment
