Heart rate information detection method, device and detection equipment

Abstract

Embodiments of the present invention relate to a heart rate information detection method, device and heart rate information detection equipment. The method includes: acquiring a heartbeat sampling signal of a first preset duration; acquiring peaks and troughs of the heartbeat sampling signal; determining the first preset according to the peaks or troughs according to the number of peaks and troughs. Real-time heart rate information over time. The heart rate information detection method, device and detection equipment provided by the embodiments of the present invention can determine whether to calculate the real-time heart rate information by peaks or valleys according to the number of peaks and valleys when acquiring real-time heart rate information. It can avoid the problem of inaccurate heart rate information caused by calculating the real-time heart rate information only by peaks or only by calculating real-time heart rate information when the BCG signal waveform changes, and can improve the accuracy of heart rate information.

Description

Technical field [0001] Embodiments of the present invention relate to physiological information detecting techniques, and more particularly to a heart rate information detecting method, apparatus, and detection device. Background technique [0002] In modern medicine, the patient's sleep situation is often monitored by monitoring heart rate. Heart pump blood changes the force of the support object that is closely contacted with the human body, currently, the heart impact signal (Ballistocardiogram, BCG) generated when the human heartbeat is collected by the micro-signal sensor, and the heart shock signal ( That is, the heartbeat signal) detects heart rate information. like Figure 1A A heartbeat signal that is normal, no waveform changes, such as Figure 1B As shown, by calculating the peak position in each heartbeat period, the time interval T (T1, T2, T3, etc.) between the two peaks can be calculated, and real-time heart rate information can be obtained. The above method does not...

AI Technical Summary

Problems solved by technology

[0003] In the process of implementing the present invention, the inventors found that there are at least the following problems in related technologies: since the micro-motion signal sensor is often placed under the bed sheet or mattress, the position of the user relative to the micro-motion signal sensor will change during the sleep process of the user. , resulting in a change in the BCG signal waveform

like Figure 1c shows the waveform change of the BCG signal from Figure 1c It can be seen from the above that, in this case, if the heart rate information is calculated only by the peak or the trough, the calculation of the heart rate information will be inaccurate
