Problems solved by technology

[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

Embodiment Construction

[0035] Specifically, such as figure 1 As shown, a kind of dynamic heart rate measuring method provided by the present invention comprises the following steps:

[0036] Step S101: After the original heart rate signal from the photoelectric sensor is basic filtered (for example, hardware filtering can be used), it is received by the MCU, and the waveform of the heart rate signal is sampled, converted into a digital signal and processed. ,.

[0037] In this step, the MCU only processes the heart rate signal, excluding all signals of the cardiac electromagnetic resonance angiography (magnetic resonance angiography, QRS) waveform. Since people are in the state of exercise, there will be many interference signals overlapping with the ECG QRS wave signal, and the amplitude of the interference signal can reach several times the ECG signal (including the heart rate signal), so in order to improve the accuracy in the calculation process, it is impossible to In the case of retaining th...

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...
