A dynamic heart rate measurement method, device and smart watch

Abstract

The invention discloses a method and device for measuring the dynamic heart rate and a smartwatch. According to the method and device for measuring the dynamic heart rate and the smartwatch, after electric signals directly received by a photoelectric sensor are subjected to hardware filtering, interference signals are intelligently filtered through low-order digital filtering software, the resting heart rate of a user is obtained through the signal cycle calculation method, and finally the resting heart rate is used as an initial filtering parameter to perform dynamic software filtering, so that the accurate dynamic heart rate of the user in the motion state is obtained, the health condition of the user can be reflected more realistically, and user experience is improved.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a dynamic heart rate measurement method, device and smart watch. Background technique [0002] Heart rate is an important physiological indicator that reflects the health of the human body. It is commonly used as medical equipment. However, in recent years, with the launch of the heart rate measurement function of the Apple Watch, heart rate measurement has been widely used in the smart wearable industry. [0003] However, wearable devices produced by most manufacturers can only measure the resting heart rate, that is, the heart rate of the user in a static state. The measurement principle is: the light emitted by the photoelectric sensor (green is the best, and red or infrared light can also be used) Arm vascular reflex, whose reflection intensity can change with the pulsation of blood vessels, the continuous change of reflection intensity can be reflected as the user's heart...

[0003] However, wearable devices produced by most manufacturers can only measure the resting heart rate, that is, the heart rate of the user in a static state. The measurement principle is: the light emitted by the photoelectric sensor (green is the best, and red or infrared light can also be used) Arm vascular reflex, whose reflection intensity can change with the pulsation of blood vessels, the continuous change of reflection intensity can be reflected as the user's heartbeat waveform, and the number of cycles per minute of this waveform is the resting heart rate

If the user measures in a static state, the resting heart rate can accurately reflect the user's real heart rate, but if the user measures in the exercise state, due to the existence of too many interference factors, the user's heartbeat waveform is irregular, and the obtained The data is divergent data, which cannot represent the real state of the user's heartbeat, so the resting heart rate cannot reflect the user's real heart rate, and the measurement accuracy should be improved
