Embodiment Construction

[0065] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0066] As a first aspect of the present invention, a heart rate monitoring method based on an audio signal is provided, wherein, as figure 1 As shown, the heart rate monitoring method based on the audio signal comprises:

[0067] S110, emitting frequency-modulated continuous waves through the loudspeaker;

[0068] S120. Receive a sound wave signal through a microphone, the sound wave signal includes a reflected sound wave signal obtained by reflecting the FM continuous wave through the chest cavity of a human body and a direct sound wave signal in which the FM continuous wave directly reaches the microphone from the speaker, and the reflected sound wave signal ...

Abstract

The invention discloses a sound signal based heart rate monitoring method. The sound signal based heart rate monitoring method includes: emitting frequency modulated continuous waves outwards througha loudspeaker; receiving sound wave signals through a microphone, wherein the sound wave signals include reflected sound wave signals obtained by human thoracic cavity reflection of the frequency modulated continuous waves and direct sound wave signals formed by the frequency modulated continuous waves directly reaching the microphone from the loudspeaker, and the reflected sound wave signals include heartbeat reflected sound wave signals and breath reflected sound wave signals; processing the sound wave signals to obtain the heartbeat. The invention further discloses a sound signal based heart rate monitoring device and a sound signal based heart rate monitoring system. By the sound signal based heart rate monitoring method, heartbeat monitoring based on sound signals is realized, a noncontact heartbeat monitoring means is provided, and convenience in monitoring and operation and low cost are realized.

Description

technical field [0001] The present invention relates to the field of mobile medical technology, in particular to an audio signal-based heart rate monitoring method, an audio signal-based heart rate monitoring device, and a heart rate monitoring system including the audio signal of the audio signal heart rate monitoring device. Background technique [0002] As an emerging technology, mobile medical monitoring uses ubiquitous mobile devices to measure human vital signs in real time. Thanks to the development of the Internet of Things and mobile sensing technology, mobile medical monitoring alleviates the problems of low frequency, high cost, and complicated use of professional equipment in the traditional medical field, and provides universal, user-friendly, sustainable and Inexpensive means of medical monitoring. [0003] Heart rate is an important vital sign that reflects the health status of the human body. However, symptoms such as heart rhythm imbalance generally occur ...
