Abstract

The invention discloses a heart rate detection method and a wearable device. The wearable device includes a housing, a processor installed in the housing, and a The optical heart rate sensing module and the distance sensing module on one side of the user's wearing part. The method includes: detecting the positional relationship between the optical heart rate sensing module and the user's wearing part through the distance sensing module, and obtaining the relative distance between the optical heart rate sensing module and the user's wearing part. location data. According to the relative position data, the signal transmission power of the optical heart rate sensing module is adjusted, and the user's heart rate is detected through the optical heart rate sensing module. The invention greatly improves the detection accuracy of the heart rate of the wearable device.

Description

Technical field [0001] The invention belongs to the field of electronic technology, and specifically relates to a heart rate detection method and a wearable device. Background technique [0002] With the rapid development of electronic technology, wearable devices realize more and more functions by detecting the user's heart rate, such as exercise monitoring, health monitoring, and sleep monitoring. [0003] In the prior art, wearable devices usually use PPG (Photoplethysmography) pulse wave method for heart rate detection, where PPG is a method for heart rate measurement based on the principle of photoelectric detection of changes in blood volume with pulse beats. The wearable device emits a light signal to the user's wearing part through an optical heart rate sensor module including an LED light and a photodetector, and detects the reflected intensity of the light signal, and the reflected intensity change frequency obtained by the detection can be obtained after processing The ...
