Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched
The specific embodiment stated is used only for explaining the present invention, rather than limitation of the invention.It also should be noted that, in order to just
Part related to the present invention rather than entire infrastructure is illustrate only in description, accompanying drawing.
Human body is kept in motion down, heart rate detection system and human body surface skin just cannot effective contact, and then now
The heart rate signal obtaining is generally inaccurate.
Embodiment one
A kind of flow chart of heart rate detection method that Fig. 1 provides for the embodiment of the present invention one, the present embodiment is applicable to the heart
Rate detects, the method can be executed by the hardware being equipped with corresponding software, specifically includes following steps：
Step S110, acquisition air bag current pressure values, and obtain the collection heart rate value mating with current pressure values；Air bag one
Side be fixedly connected on detecting system or detection means body, opposite side then presses close to human body surface skin, the pressure value of air bag
The actually detecting system or detection means body pressure value to the human body surface time.Detecting system or detection means can adopt sound
Pressure detection mode obtains collection heart rate value.
Further, human body surface skin can be the skin corresponding to posterior auricular artery region, little because of posterior auricular artery region
Sweat gland is less, and the perspiration that motion is perspired is also relatively small, and air bag contacts human body surface skin, human body surface by direct friction
After coupling occurs, air bag will become " slip " friction with the direct friction of human body surface skin, and then the accuracy gathering has
Declined, thus as further preferred scheme, human body surface skin can be the skin corresponding to posterior auricular artery region, improves pressure
Force value and/or the collection accuracy of collection heart rate value.
Step S120, judge the described pressure value whether effective threshold signal of matching pressure or the invalid threshold signal of pressure；And
Form judged result output；
Step S130, send out in the state of described judged result is the described pressure value coupling invalid threshold signal of described pressure
Go out alarm；In the state of described judged result is the described pressure value coupling invalid threshold signal of described pressure, judge detection system
System or detection means body is not yet in effect with human body surface skin contacts.
The air bag of the present invention can for can not pressurizing balloon, alternatively can pressurizing balloon, when air bag be can not pressurizing balloon when,
If described judged result is described pressure value mates the invalid threshold signal of described pressure, usually wearing mode is inaccurate leads
Cause.When air bag be can pressurizing balloon when, if described judged result is described pressure value mates the invalid threshold signal of described pressure,
Be usually that wearing mode is inaccurate leads to, wearing mode inaccurate so that air bag cannot effectively stress it is also possible to be in air bag
Air pressure not enough, need air bag is done with pressurising and process.The reason contact not yet in effect, may have a lot.It is only for example herein, rather than
Limitation of the invention further.
Step S140, in the state of described judged result is the described pressure value coupling effective threshold signal of described pressure,
Calculated according to described pressure value, described collection heart rate value and pressure criteria value and form heart rate signal output.

Rate value；Judge the described pressure value whether effective threshold signal of matching pressure or the invalid threshold signal of pressure；And form judged result
Output；By the pressure value of air bag judge detecting system or detection means body whether with human body surface skin effective contact,
In the state of described judged result is the described pressure value coupling invalid threshold signal of described pressure, judge detecting system or detection dress
Put that body is not yet in effect with human body surface skin to be contacted, now send alarm and reminding user's current state cannot obtain the effective heart
Rate value, in the state of described judged result is the described pressure value coupling effective threshold signal of described pressure, judges detecting system
Or detection means body is not yet in effect with human body surface skin contacts, according to described pressure value, described collection heart rate value and pressure mark
Quasi- value calculates and forms heart rate signal output.
In the present invention, detection to current pressure values, judge that detecting system is had with human body surface skin by this pressure value
Effect contact, calculates in the state of detecting system with human body surface skin effective contact and forms heart rate signal output.In the present invention,
On the one hand, when judge detecting system invalid with human body surface skin contact to send alarm and reminding user and currently gather adopt for invalid
Collection, need to do corresponding adjustment to obtain effective collection, on the other hand, according to described pressure value, the described collection heart to detecting system
Rate value and pressure criteria value calculate and form heart rate signal output, it is to avoid because detecting system is low to human body surface skin formation pressure
Cause output heart rate signal inaccurate, be intended to improve the accuracy in detection of heart rate signal by said method.
It should be noted that：In detecting system or detection means body, an air pump can also be set, when described judged result
For air bag being done in the state of the described pressure value coupling invalid threshold signal of described pressure with inflation process and/or sending alarm.With
The atmospheric pressure value in air bag is made to mate effective threshold signal.The technique effect phase of the technique effect of this kind of mode and technique scheme
Seemingly, the equivalent to above-mentioned technique effect.
