Abstract

The application discloses a heart rate detection method and a heart rate detection device. The heart rate detection method includes: receiving a photoplethysmography sensor signal and a motion signal; determining the state of the human body according to the motion signal; calculating the spectrum of the photoplethysmography sensor signal; and obtaining the spectrum of the photoplethysmography sensor signal with motion noise removed based on the spectrum of the motion signal; and calculating the estimated heart rate value according to the spectrum of the photoplethysmography sensor signal with motion noise removed. By distinguishing the motion state of the human body, the method removes the interference noise caused by the motion to the signal of the photoplethysmography sensor, improves the accuracy of heart rate calculation, saves power consumption, and improves detection efficiency.

Description

technical field

[0001] The invention belongs to the technical field of heart rate detection, in particular to a heart rate detection method and a heart rate detection device. Background technique

[0002] Heart rate refers to the number of times the human heart beats per minute. In the detection of human body parameters, heart rate is a very important physiological indicator, which provides a reference for medical diagnosis. At the same time, heart rate, as an objective evaluation index of the physiological load of human exercise, has been widely used in various aspects of fitness and competitive sports training.

[0003] Photoplethysmography (PPG) is a non-invasive heart rate detection method that detects changes in blood volume in living tissue by means of photoelectric means. When the light beam of a certain wavelength is irradiated on the skin surface, the light beam will be transmitted to the photoelectric receiver through transmission or reflection. During this proc...
