The invention relates to a heart rate signal processing method and device based on head pulse waves and an electronic device. A heart rate value calculation method comprises the steps: acquiring original head pulse wave signals, collected in a preset time period, of a measured object, determining a filtering range according to historical heart rate values of the measured object before the preset time period, performing band-pass filtering on the original head pulse wave signals based on the filtering range to obtain a filtering signal, extracting a peak value from the filtering signal, and calculating the heart rate of the measured object in the preset time period based on the peak value. The anti-interference capability of a pulse wave signal processing process on the action of the measured object is improved, the influence of external factors on heart rate value calculation is lowered, and therefore, stable and accurate calculation of the heart rate value is achieved.
Description
technical field [0001] The present application relates to the field of signal processing, in particular to a heart rate signal processing method, device and electronic device based on head pulse waves. Background technique [0002] The heart rate value is an important indicator reflecting the health status of the body. Real-time detection of the heart rate value of the human body through the wearable device can realize real-time tracking of the physical condition. At present, the main method of heart rate detection based on the piezoelectric pulse wave signal is to obtain the pulse wave signal of the wrist of the measured object by installing an acquisition device on the wrist of the measured object, and then use the obtained wrist pulse wave signal for heart rate detection. Since in daily life, the wrist is more frequently moved, which will cause more interference to the pulse wave signal, which makes the anti-interference performance of this method poor, resulting in low...
