Heart rate detection method and heart rate detection device for enhancing accuracy

Abstract

The invention provides a heart rate detection method and a heart rate detection device for enhancing the accuracy. The heart rate detection method includes S100, acquiring first heart rate detection values and first credibility values corresponding to the first heart rate detection values; S200, comparing the first credibility values to preset credibility thresholds and acquiring current heart rate values by means of computation according to comparison results. The heart rate detection device comprises an acquisition module and a control module. The control module is connected with the acquisition module; the first heart rate detection values and the first credibility values corresponding to the first heart rate detection values can be acquired by the acquisition module; the first credibility values can be compared to the preset credibility thresholds by the control module, and the current heart rate values can be acquired by the control module by means of computation according to thecomparison results. The heart rate detection method and the heart rate detection device have the advantages that the heart rate detection accuracy can be enhanced by the aid of the heart rate detection method and the heart rate detection device, and accordingly heart rate detection results are close to actual heart rate values of users.

Description

technical field [0001] The invention relates to the field of heart rate detection, in particular to a heart rate detection method and device for improving accuracy. Background technique [0002] With the improvement of living standards, people begin to pay more attention to the health of themselves and their families. Therefore, wearable devices such as watches and wristbands are becoming more and more popular in the market, because they can monitor many conditions of the human body, such as step counting, sleep monitoring, heart rate monitoring, etc. [0003] For the heart rate monitoring on wearable devices, in the prior art, the measurement is carried out by photovolume scanning method, that is, by turning on the green LED light, and then using CMOS to collect the reflected light, and then using a certain algorithm to roughly calculate the heart rate of the human body. heart rate value. [0004] Since the heart rate detection in the prior art is carried out by using the...

AI Technical Summary

Problems solved by technology

[0004] Since the heart rate detection in the prior art is carried out by using the reflection of light, it is easy to be affected by the external environment and the person being tested. For example, when people sweat, or people with darker skin, the reflection of light will be seriously affected. influence, so the accuracy of the measurement cannot be guaranteed
