System and method for implementing detection on pulse and heart rate and monitoring on emotion and fatigue degree

Abstract

The invention relates to a system and a method for implementing detection on a pulse and a heart rate and monitoring on an emotion and a fatigue degree. The system comprises an optical detection module, a pulse wave signal calculation module, a heart rate and heartbeat interval calculation module, a heart rate variation index calculation module and an emotion and fatigue degree estimation module, wherein the optical detection module is used for detecting information about skin surface light intensity variation caused by variation of a blood-flow volume in blood vessels of a user after light of at least one LED (Light-Emitting Diode) irradiates the surface of skin; the pulse wave signal calculation module is used for acquiring a pulse wave signal according to the light intensity variation information; the heart rate and heartbeat interval calculation module is used for calculating the heart rate and interval time of each stroke of heartbeat; the heart rate variation index calculation module is used for carrying out analysis on a heart rate or heartbeat time interval sequence to obtain related indexes of heart rate variation; the emotion and fatigue degree estimation module is used for estimating the fatigue degree and the emotion state according to the related indexes of the heart rate variation. The system and method for implementing detection on the pulse and the heart rate and monitoring on the emotion and the fatigue degree, which adopt the structure, are greatly improved in comfort and convenience, are economic and practical and have a wider application range.

Description

technical field [0001] The present invention relates to the technical field of health monitoring, in particular to the technical field of pulse and heart rate detection, and specifically refers to a system and method for realizing pulse and heart rate detection as well as emotion and fatigue level monitoring. Background technique [0002] The currently commonly used heart rate / pulse measurement method is mainly obtained by analyzing the signals collected by the blood oxygen sensor, that is, the red light and infrared light modules, and the infrared light is easily affected by temperature. Fatigue and emotional state can be assessed by subjective and objective methods. It is difficult to quantify the level and degree of fatigue by subjective evaluation methods; objective evaluation mainly determines the degree of fatigue and emotional state through EEG, ECG, EMG waveform or galvanic skin response. Most HRV (HeartRateVariability, heart rate variability analysis) analysis and ...

AI Technical Summary

Problems solved by technology

Most HRV (HeartRateVariability, heart rate variability analysis) analysis and emotion and fatigue analysis are based on patching at designated body surface locations and collecting electrocardiogram / electrocardiogram sequence (ECG or EKG) data for detection and analysis, not only comfort and convenience Not good, and the price is relatively expensive, and most of the patches are disposable, not very environmentally friendly
