Embodiment Construction

[0032] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0033] Such as figure 1 As shown, a method for detecting heart rate is provided in one embodiment of the present invention, comprising:

[0034] Step 110, collecting heart rate signals. In this embodiment, there is no limitation on the manner of collecting the heart rate signal. For example, the camera of the mobile terminal may be used to obtain the PPG signal to detect the heart rate.

[0035] Step 120, extract the heart rate feature from the waveform corresponding to the heart rate signal. In this embodiment, there is no limitation on the type of extracted heart rate feature, and any feature based on waveform is applicable to the technical solution of this embodiment.

[0036] Step 130, judging whether the heart rate feature meets a preset condition. In this embodiment, the preset condition can be any condition...

Abstract

The invention discloses a method and device for detecting heart rat. The method includes: collecting a heart rate signal; extracting heart rate features from the waveform corresponding to the heart rate signal; judging whether the heart rate features conform to preset conditions or not; if so, outputting the corresponding heart rate according to the heart rate signal. The method has the advantages that due to the fact that the waveform of the normally detected heart rate signal has some common features, whether the heart rate detection is performed under normal conditions or not can be judged according to the features of the waveform, the heart rate signal under the normal conditions is stable in waveform, whether the waveform changes or not needs not to be detected constantly, the heart rate can be fast calculated favorably, the correct heart rate can be obtained by using the heart rate signal under the normal conditions to calculate the heart rate, and mistakes can be avoided.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for detecting heart rate. Background technique [0002] As an important information reflecting a person's health, heart rate has attracted much attention. Medical heart rate detection is based on ECG (ElectroCardioGram, electrocardiogram) signals. The measurement method is complicated, usually requires the assistance of others, and the equipment is not easy to carry. [0003] Recently, wearable, handheld and other smart devices accept the user's finger to press the camera, and use a certain wavelength of light (such as 660nm-720nm red light) to irradiate the user's finger and collect PPG (PhotoPlethysmoGraphy, photoplethysmography) signal through the camera. Take a heart rate measurement. Smart devices like wristbands and mobile phones are more portable, so they are good for real-time measurement. At present, more and more smart devices are adding this fu...
