That is, determine for calculating the not exclusively multi-group data of data used in the parameter of pressure value, and it is multigroup
It is the data of different conditions that data are corresponding, meanwhile, a kind of state can correspond at least one set of data, many in a kind of state correspondence
In the case of group data, the multi-group data for being directed to same state can be the data of different periods.
For example, being directed to the less state of exercise intensity, there is three groups of data, be respectively morning hours, the period at noon with
And data the period in the evening.
For another example being directed to the medium state of exercise intensity, there are two groups of data, be morning hours and respectively the period in the evening

Deng state, strenuous exercise's state representation is the larger state of exercise intensity.
Below, enter for the acquisition process of one group of data (data i.e., in the first state) in the embodiment of the present invention
Row simple declaration.
The pressure value of user in the first state is gathered by the sphygmomanometer of medical certification, by input block 120 by blood
In the sphygmomanometer of the pressure value input embodiment of the present invention, meanwhile, pass through the detecting signal unit in the sphygmomanometer of the embodiment of the present invention
User's ECG signal in the first state and PPG signals are gathered, and then, processor 130 is carried out to PPG signals and ECG signal
Processing, obtains PTT, in this manner it is possible to achieve one under being directed to first state group data, i.e. the pressure value of systolic pressure, diastole
The pressure value and PTT of pressure.
So, different conditions are directed to, said process is repeated, the multi-group data of different conditions are obtained, so as to complete data
The process of collection.
If it should be noted that the first state is not inactive state, then, just gather blood pressure after user movement is complete
Value, PPG signals and ECG signal.
In addition, the time sequencing of collection pressure value and collection PPG signals and ECG signal is not limited, pressure value is gathered
Time can collection PPG signals and ECG signal time before, can also collection PPG signals and ECG signal time
Afterwards.But, gather interlude difference between the time of pressure value and collection PPG signals and the time of ECG signal oversize.
Generally, if first gathering pressure value, collection PPG signals and ECG letters can be started by having gathered pressure value after 1-3 minutes
Number；If first gathering PPG signals and ECG signal, having gathered can start to gather blood pressure after PPG signals and ECG signal after 1 minute
Value.
It should be understood that the pressure value described in the embodiment of the present invention there are two kinds, include the pressure value and systolic pressure of diastolic pressure
Pressure value.
In S220, processor 130 is according to the M group data, it is determined that parameter during for being taken blood pressure using the blood pressure measuring
Set.
That is, the processor 130 in the sphygmomanometer is stored in memory by obtaining the M groups data and calling
Being used in 140 represents the program of blood pressure detecting model, it is determined that parameter sets during for being taken blood pressure using the blood pressure measuring, should
Parameter sets can include following at least one set of parameter：First group of parameter, including for representing the function between diastolic pressure and PTT
The parameter of relation；Second group of parameter, including for representing the parameter of the functional relation between systolic pressure and PTT.
Alternatively, this is according to the M groups data, it is determined that the parameter set used during for being taken blood pressure using the blood pressure measuring
Close, including：
First group of parameter in the parameter sets is determined according to the M groups data and the first formula, every group of data include should
The pressure value of systolic pressure of the user under corresponding motion state, first formula isThe asAnd bsFor
Parameter in first group of parameter, the SBP represents systolic pressure, and the H represents the height of the user；And/or,
Second group of parameter in the parameter sets is determined according to the M groups data and the second formula, every group of data include should
The pressure value of diastolic pressure of the user under corresponding motion state, second formula isThe DBP is represented
Diastolic pressure, adAnd bdFor the parameter in second group of parameter, the H represents the height of the user.
That is, in embodiments of the present invention, the formula (in other words, blood pressure detecting model) for calculating pressure value can
To be：Wherein, what a and b were represented is parameter, and what BP was represented is pressure value, and what H was represented is the body of user
It is high.
For systolic pressure, above-mentioned formula can be the first formula, i.e.,Wherein, asAnd bsIt is to represent
The parameter of functional relation between systolic pressure and PTT, by the pressure value and corresponding M of M systolic pressure in the M group data
PTT brings above-mentioned first formula into respectively, obtains first group of parameter in parameter sets, i.e. asAnd bs。
For diastolic pressure, above-mentioned formula can be the second formula, i.e.,adAnd bdIt is to represent diastole
The parameter of functional relation between pressure and PTT, by the pressure value and corresponding M PTT of M diastolic pressure in the M group data
Bring above-mentioned second formula into respectively, obtain second group of parameter in parameter sets, i.e. adAnd bd。
Non-limiting as example, the formula (in other words, blood pressure detecting model) for calculating pressure value can be not only
Formula as described above, can be other formula, for example, BP=a+bln (PTT), BP=a+bPTT, wherein, a here
Also contribute to represent the parameter of the functional relation between PTT and pressure value with b.
Accordingly it is determined that after parameter in parameter sets, it is possible to pass through the PTT of sphygmomanometer direct measurement user, Jin Ertong
The functional relation (in other words, blood pressure detecting model) crossed between PTT and pressure value determines the pressure value of user.
In the prior art, the blood pressure measurement mode based on individual calibration, the data for calibrating blood pressure detecting model are one
Secondary property collection, on the one hand, ECG signal and PPG signal noises are larger so that the PTT obtained after processing compared to real PTT it
Between there is certain error, less data make it that this error caused due to measurement process is larger；Meanwhile, disposable collection
Data can not consider pressure value of the user in different conditions, especially for for continuity blood pressure measurement, it is necessary to measure use
Pressure value of the family in 24 hours one day, user can have various states in one day, measurement can not be met well different
The demand of pressure value under state, that is to say, that the degree of accuracy of measurement blood pressure is relatively low.And in embodiments of the present invention, by obtaining
Multi-group data of the family in different conditions is taken, more data can be not only efficiently reduced due to the mistake that processing procedure is caused
Multi-group data under difference, and different conditions can improve the blood pressure measurement scope of sphygmomanometer, so as to improve the accurate of blood pressure measurement
Degree.
Thus, the method for calibration sphygmomanometer provided in an embodiment of the present invention is more under different conditions by obtaining user
Group data, at least one set of data of every kind of state correspondence, every group of data include user pressure value and PTT under corresponding states, one
Aspect, more data can reduce the error of measurement process, so that the degree of accuracy of blood pressure measurement is improved, it is on the other hand, different
State of the multi-group data due to considering user under state so that blood pressure detecting model goes for larger blood pressure measurement
Correlation between scope and PTT, i.e. blood pressure measurement scope can be effectively improved, so that, it is favorably improved blood pressure measurement
The degree of accuracy.
Alternatively, the M group data are the data in the K period in calibration cycle, at least one of N kind states shape
Every kind of state correspondence K group data in state, K period of the K groups data and this corresponds, and the K group data belong to the M group numbers
According to the K is the integer more than 1.
Specifically, the M groups data are related to the state of user, also related to the period, i.e., the M group data are K periods
Interior data, are directed to the same state at least one state, can gather multi-group data of the user in different periods,
That is, every kind of state correspondence K group data at least one state, and the K groups data and K period one-to-one corresponding.Namely
Say, partial status can gather the data in K period, partial status can be gathered less than the data in K period.
For example, N is 3, and correspondence three state, K is 3, and corresponding respectively is morning hours, period at noon and the period in the evening,
M is 7,7 groups of data of correspondence：Wherein, 3 groups of data of morning hours correspondence, i.e. 3 group data of the collection user under three state；In
The period of the day from 11 a.m. to 1 p.m 2 groups of data of section correspondence, i.e. 2 group data of the collection user under 2 kinds of states, 2 kinds of states of period at noon can be 3 kinds
Any 2 kinds of states in state；2 groups of data of correspondence, i.e. 2 kind data of the collection user under 2 kinds of states, evening the period in the evening
2 kinds of states of period can be any 2 kinds of states in three state；That is, for a kind of state in three state, point
Not Cai Ji 3 group data of the user in 3 periods, other two state gathers 2 group data of the user in 2 periods respectively,
And different conditions can correspond to the different periods.
It is non-limiting as example, the K period can also be refined, the period can be defined with default duration.
For example, preset duration is 2 hours, i.e. 2 hours are a period, and number of the user in different conditions can be gathered at interval of 2 hours
According to.
Thus, during the blood pressure measuring is taken blood pressure, alternatively, this method also includes：
L PTT at least two periods in K period of the user in measurement period is obtained, this at least two
In period each period correspondence at least one PTT, the measurement period corresponding time the calibration cycle corresponding time it
Afterwards, the K period in the measurement period corresponds with the K period in the calibration cycle, and the L is the integer more than 1；
I-th of PTT and the parameter sets in the L PTT, it is determined that pressure value corresponding with i-th of PTT, institute
State i ∈ [1, L].
, can be by obtaining multiple PTT of different periods, so that according to the blood pressure that is, in actual use
Detection model, obtains pressure value corresponding with multiple PTT.
For the same period, the PTT under different conditions can be obtained, i.e. at least one PTT of each period correspondence, one
A state in PTT one period of correspondence.That is, within a period, user can be obtained under a state
Data, can also obtain data of the user under multiple states.
Wherein, i ∈ [1, L] represent to travel through L PTT, i.e. according to any one PTT (i.e. i-th PTT) and parameter sets,
