Technical field
The present invention relates to a kind of heart rate breathing detection method and system more particularly to a kind of contactless heart rate to breathe inspection
Survey method and system.
Background technology
Heart rate and breathing are the most important physiological parameters of human body, and the existing detection mode to heart rate and breathing mainly has following
Two kinds：
(1) it is worn on human body by Wearable, is measured by way of being in direct contact human body and shows that human body is worked as
Preceding heart rate and breathing.But the existing usual burdensome of Wearable, when human body wears Wearable, feel stupid
My and it is uncomfortable.
(2) physiologic motion sensors based on radar are detected, and are given birth to from radiation source by way of contactless humanbody
At electromagnetic radiation, the signal for each frame returned from Human feed back is then received, signal is handled, and then obtained human body and work as
Preceding heart rate and breathing.But radar emission has harm to human body, can influence the health of human body instead.
Invention content

Referring to Fig. 1, its flow chart for the heart rate breathing detection method in the embodiment of the present invention.The heart rate breathing detection
Method includes the following steps：
Step S1：Obtain the heart rate breath signal of heart rate device for detecting respiratory acquisition；Wherein, the heart rate breathing detection dress
It sets including for being fixed in the extraneous bearing structure of carrying human body and flexible cloth body and acceleration transducer, institute
Acceleration transducer is stated to be arranged on the cloth body.
In one embodiment, the cloth body is preferably the cloth that canvas etc. has certain elasticity, by by acceleration sensing
Device be arranged on cloth body, then by cloth body be arranged carrying human body bearing structure such as nylon bed under or canvas chair under,
And then when can prevent human body from sitting suddenly and/or lying in bearing structure by flexible cloth body, by acceleration transducer from carrying
It pops up and is detached from structure；Further, people sits and/or when lying in bearing structure, and heart rate bounce and breathing generate smaller
The vibration of amplitude will be amplified by flexible cloth body, so can be obtained by acceleration transducer the heart rate vibration and
Breathing vibration, that is, heart rate breath signal.And by by flexible cloth body to human heart rate beat and breathe generate more by a small margin
Vibration be amplified, compared to directly by acceleration transducer be arranged bearing structure measure human heart rate bounce and breathing produce
The mode of raw vibration more by a small margin is more accurate.
In one embodiment, the acceleration transducer uses the stronger sensor of sensitivity, specifically model
Six axle sensors of MPU6050.
Step S2：Kalman filtering and the processing of band logical Butterworth filter are carried out to the heart rate breath signal, obtained
Heart rate breath signal after denoising.
Step S3：Judge whether the heart rate breath signal after denoising is effective, if in vain, continuing to obtain detection device acquisition
Heart rate breath signal, that is, return to step S1；Otherwise, effective heart rate breath signal is divided into two-way to be respectively processed, one
The effective heart rate breath signal in road sequentially carries out shape filtering, auto-correlation computation and Interspace interval extraction process, obtains heart rate letter
