Problems solved by technology

However, this method also has major limitations. For example, different races and different skin colors have different light absorption of different wavelengths. When the human body is sweating, the light reflectance is also different. Devices are difficult to achieve more accurate heart rate detection

Embodiment Construction

[0015] The present invention is further described in conjunction with the following examples.

[0016] In order to detect the heart rate in real time, the user wears a smart bracelet with a built-in adaptive switching heart rate detection device based on the spectrogram, such as figure 1 As shown, there are photoelectric signal acquisition modules PD2 and PD3 for collecting and recording the photoelectric signal of the skin surface under green light (color light A) in the smart bracelet, and for collecting the skin surface under red light or infrared light (color light B). ) under the photoelectric signal acquisition modules PD1 and PD4. The photoelectric signal acquisition modules PD1, PD2, PD3, and PD4 are placed in the smart bracelet, and there is a transparent glass material between them and the skin. The photoelectric signal acquisition modules PD1, PD2, PD3, and PD4 can also be placed outside the smart bracelet. The part that is in direct contact with the skin to reduce...

Abstract

The invention relates to the technical field of heart rate detection, in particular to a self-adaption heart-rate-switching detection method based on a spectral pattern and a wearable heart rate detection device. Electrocardio signals obtained under colored light are subjected to fourier transformation mapping to form a spectral intensity pattern distributed according to the time-frequency point relationship, a time connecting line of user-heart-rate-frequency peak value areas in the spectral intensity pattern serves as a heart-rate variation curve, the effectiveness of heart-rate signal collection of current colored light can be judged through the continuity of the heart-rate variation curve, and optoelectronic signals collected under the current colored light is indistinct; in other words, when the heart-rate variation conditions cannot be clearly reflected, the current colored light is instantly switched into colored light with the higher penetrability for collecting the electrocardio signals to guarantee the continuity and the accuracy of heart-rate detection. For the self-adaption heart-rate-switching detection method based on the spectral pattern, a functional module framework can be combined by establishing functional modules, and implementing is carried out through computer programs stored in a readable storage medium of a computer.

Description

technical field [0001] The invention relates to the technical field of heart rate detection, in particular to a spectrogram-based self-adaptive switching heart rate detection method and a wearable heart rate detection device. For the spectrogram-based self-adaptive switching heart rate detection method, functional modules can be established, combined into a functional module framework, and implemented by a computer program stored in a computer-readable storage medium. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for health. Among them, many people choose aerobic exercise such as running, which can effectively consume calories, exercise cardiopulmonary function and even improve sleep quality, as a daily exercise program. Heart rate has always been the most direct indicator for measuring the proportion of aerobic exercise. Knowing your own maximum aerobic heart rate will help sports enthusiasts exercise heal...
