Specific embodiment
In order to make those skilled in the art more fully understand application scheme, with reference to the accompanying drawings and detailed description
The application is described in further detail.Obviously, described embodiments are only a part of embodiments of the present application, rather than
Whole embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall in the protection scope of this application.
Human heart rate is the whether good important reference factor of human health status, how to be obtained more accurate
Heart rate data, it is significant to analysis human health status.Therefore, conventional utilization photoplethysmography measures people
When the rate of body-centered, the acceleration information of the movement of human body is often detected simultaneously, is obtained more accurately to integrate acceleration information
Dynamic Heart Rate data.But when due to measurement heart rate data and acceleration information, obtains frequency and all exist in time centainly
Error, when finally to calculate Dynamic Heart Rate, the heart rate data and acceleration information of use cause to calculate and obtain there are time warping
Obtain the problem of Dynamic Heart Rate data inaccuracy.
Therefore, the technology that heart rate data and acceleration information there is technical issues that is able to solve in the application
Scheme, below just the technical solution is described in detail with specific embodiment.
As shown in FIG. 1, FIG. 1 is the flow diagrams of Dynamic Heart Rate data capture method provided by the embodiments of the present application, should
Method may include:
Step S1: the heart rate data group and acceleration information group detected within a preset period of time is obtained.
Specifically, heart rate data group is multiple heart rate numbers detect within a preset period of time and that theory detection frequency is F1
According to；Acceleration information group is multiple acceleration informations detect within a preset period of time and that theory detection frequency is F2.
Step S2: judge the acceleration information number in the heart rate data number and acceleration information group in heart rate data group
Whether ratio a is equal to F1:F2, if it is, S3 is entered step, if it is not, then entering step S4.
Step S3: the number of acceleration information in amendment acceleration information group makes ratio a=F1:F2, generates revised
Acceleration information group.
Step S4: storage heart rate data group and acceleration information group.
It should be noted that needing to acquire heart rate data and acceleration simultaneously in doing Dynamic Heart Rate algorithm in detection heart rate
Degree evidence, and collected data are stored in SD card, it is analyzed for Dynamic Heart Rate algorithm.
Since heart rate sensor and acceleration transducer are two independent components, there is respective reference clock, and each
From reference clock all can there is a certain error, so sample frequency is caused to have deviation.For example, photoplethaysmography
(PPG) sample frequency is 40Hz, and the sample frequency of acceleration transducer (ACC) is that 50Hz is ideally stored in SD card
The quantitative proportions of two groups of data should be 40:50.But due to clock jitter, the ratio of two groups of data volumes is caused to deviate this
Ratio, if according to 40:50, this ratio goes to take acquisition heart rate data and acceleration information when this will lead to final analysis data,
It will cause temporal dislocation, for example obtaining the data of PPG is the data of 1s, the data of the ACC taken may be the number of 5S
According to, this can analyze to algorithm and bring problem, and the initial time that when detection time distance of acquired data is opened is detected is longer,
The dislocation of data in time is more serious.
Pass through the number of the data of number and acceleration to the heart rate data obtained in the same period in the present embodiment
Ratio compare, the ratio of the number of heart rate data and acceleration information is modified, so that being stored in SD card
The quantity of heart rate data and acceleration information keeps identical with theoretic sample frequency ratio, then when needing in SD card
When data are analyzed, heart rate data and acceleration information directly are obtained according to the ratio of theoretical sample frequency, that is, can guarantee institute
There is no dislocation in sampling time point for the heart rate data and acceleration information of acquisition.
Specifically, because to heart rate data and acceleration information generally by photoplethaysmography (PPG) and acceleration
The detection of sensor duration can detect heart rate data and acceleration since identical starting timing in the actual operation process
Degree evidence, after preset time period, just by the quantity of the heart rate data detected in the preset time period and acceleration degree
According to the ratio of quantity compare, guarantee the quantity and acceleration information of the heart rate data got in the preset time period
Quantitative proportion is identical with the theoretical ratio of sample frequency, later again using the end time of this preset time period as new timing
Starting point, in preset time period after the time zero heart rate data and acceleration information carry out above-mentioned repetition detection correction
Operation, finally makes the quantitative proportion and interest rate sample frequency ratio phase of the heart rate data stored in SD card and acceleration information
Together.For the duration of each preset time period, the period of identical duration can be, that is to say pair according to fixed time period
The quantitative proportion of the heart rate data and acceleration information that detect in cycle time is detected and is corrected；It can also be different duration
Preset time period, as long as finally the data that store into SD card have all carried out comparison amendment.
In addition, the accuracy of heart rate data is relative to acceleration information for the data for calculating Dynamic Heart Rate
Accuracy is even more important, so often being corrected by the way of being modified to acceleration information when revising to data.
In the application by predetermined amount of time detect to heart rate data and acceleration information number ratio carry out
It examines and corrects, finally make the quantitative proportion of the heart rate data obtained for calculating Dynamic Heart Rate data and acceleration information
It is identical with theoretical sample frequency ratio, when avoiding according to data progress Dynamic Heart Rate calculating, due to heart rate data and acceleration
There are time warpings between for degree, and lead to the problem for calculating the Dynamic Heart Rate data inaccuracy obtained, improve to the human body heart
The accuracy of rate monitoring of pulse helps user to guard heart rate fitness at any time, guarantees that user is physically and mentally healthy.
As previously mentioned, for when the heart rate data number and acceleration degree in the heart rate data group detected in preset time period
When being not equal to F1:F2 according to the acceleration information number ratio a in group, need to the acceleration information number in acceleration information group
It is revised.But the acceleration information number ratio a in the heart rate data number and acceleration information group in heart rate data group
Not equal to F1:F2, there are two kinds of situations, and one is ratio a to be greater than F1:F2, and one is ratio a to be less than F1:F2.Below just to this
Two different situations are illustrated the correcting mode of the number of acceleration information in acceleration information group.
In a kind of specific embodiment of the application, the number for correcting acceleration information be can specifically include:
If the ratio a is greater than F1:F2, the acceleration information in acceleration information group is replicated as complementary acceleration
Data；
The adjacent position of the acceleration information being replicated in acceleration information group increases complementary acceleration data, so that institute
Ratio a is stated equal to F1:F2.
It should be noted that having multiple acceleration informations in acceleration information group, and ratio a to be made to be equal to F1:F2,
Generally only require supplementation with a few acceleration information.So specifically how to supplement, there are a variety of different schemes.
Optionally, in the another specific embodiment of the application, the number for correcting acceleration information be can specifically include:
If ratio a is greater than F1:F2, the number b of the acceleration information required supplementation in acceleration information is determined；
It chooses b acceleration information duplication in the acceleration information group and is used as complementary acceleration data；
The adjacent position of each acceleration information being replicated increases separately corresponding benefit in the acceleration information group
Fill acceleration information.
It should be noted that the data either in heart rate data group or acceleration information group are finally to be used for dynamic
The calculating of heart rate data, the acceleration information group and heart rate data group therefore, in identical preset time period detected are in time
Correspondingly, it is understood, therefore, that the data arrangement sequence in heart rate data group and acceleration information group also necessarily
What it is with the detection time point of the data detected is successively tactic.
For human body, in the such very short time interval of sample frequency, acceleration magnitude and adjacent time point
Acceleration magnitude difference it is not too large, adjacent time point replicate increase an equal-sized acceleration information, be equivalent to
Think that the acceleration information being replicated does not change in the acceleration magnitude of the adjacent time point at its detected time point, this
Although there is a certain error for kind of an amendment, when relative to heart rate data and acceleration information generation time mistake bring error,
Have and significantly reduces.
It only needs any acceleration information for choosing b quantity to be replicated in the present embodiment, is then added to acceleration degree
According in group, but the increased position of complementary acceleration data that should ensure that duplication obtains must be with the original acceleration information being replicated
It is adjacent, it thus can just think that the complementary acceleration data that the acceleration information being replicated and duplication obtain are that adjacent time point is examined
The data of survey.
Optionally, in a kind of specific embodiment of the application, if the ratio a is greater than F1:F2, for how to obtain
Complementary acceleration data can also further include:
The last one acceleration information in acceleration information group is replicated as complementary acceleration data；
The adjacent position of the acceleration information being replicated in acceleration information group increases complementary acceleration data, so that than
Value a includes: equal to F1:F2
Least significant end increases at least one complementary acceleration data in acceleration information group, so that ratio a is equal to F1:F2.
It is understood that the data arrangement sequence in acceleration information group is the detection time point with the data detected
Successively to be tactic.The last one acceleration information is one of detection time point the latest so in acceleration information group
A data.When correcting acceleration information group, the data that complementary acceleration data should be used as last position in acceleration information group are added
Acceleration information group.
It should be noted that only being conducive to simplify with the so-called acceleration information being replicated of the last one acceleration information
The process for correcting the data accelerated, without obtaining complementary acceleration data and then searching the original acceleration being replicated
The arrangement position of data.
But randomly select multiple acceleration informations in acceleration information group and replicated, be conducive to supplement adds
Error brought by speed is dispersed, and acceleration information in excessive detection time point is avoided not generate variation, cause and
The problem of actual conditions are not consistent.
Optionally, when being less than F1:F2 for ratio a, to the correcting mode of acceleration information, in the another specific of the application
In embodiment, can further include:
If ratio a is less than F1:F2, deletes and is located at least one last acceleration information in acceleration information group,
So that the ratio a is equal to F1:F2.
It is same as above, in acceleration information group, positioned at a last acceleration information, it that is to say detection time point the latest
A data.
It should be noted that heart rate data is relative to acceleration information for the data for calculating Dynamic Heart Rate
It is even more important because for human body, in the such very short time interval of sample frequency, acceleration magnitude and it is adjacent when
Between put acceleration magnitude difference it is not too large, increase the acceleration of a few same size in acceleration information group least significant end
Data are unlikely to the accuracy rate of the calculating of entire Dynamic Heart Rate data to generate too much influence.
In addition, the dislocation as described previously for heart rate data and acceleration information in time, being can be with the increasing of time
It is long and accumulate, therefore, when to the inspection of heart rate data and acceleration information in preset time period, the duration of preset time period
, neither can be too short with regard to needing to be appropriately arranged with, cause the preset time period divided excessive, the corresponding heart rate data for needing to examine
Group and acceleration information group are also more, can not be too long by the setting of the duration of preset time period, lead to preset time period heart
Rate data and the dislocation of acceleration information accumulated time are excessive, result in the need for increasing excessive complementary acceleration or delete excessive end
Tail acceleration causes finally to calculate the heart rate acceleration inaccuracy obtained, it is however generally that predetermined time period setting is on the left side 500ms
The right side.
Based on above-mentioned any embodiment, in the another specific embodiment of the application, can also further include:
If the acceleration information number ratio a in the heart rate data number and acceleration information group in heart rate data group is not
Equal to F1:F2；
In the preset time period for then judging predetermined quantity, ratio a whether steady state value, if it is, updating heart rate data
It is ratio a that theory, which obtains frequency F1 and the theoretical ratio obtained between frequency F2 of acceleration information,.
It should be noted that because to the quantity of heart rate data and acceleration information having been inspected to a preset time period
Cheng Hou then tests to the data of next preset time period.If in the equal preset time period of continuous multiple durations, the heart
Acceleration information number ratio a in heart rate data number and acceleration information group in rate data group is steady state value, and is differed
In F1:F2, then illustrate the theoretical sample frequency inaccuracy of heart rate data or acceleration information, it can be by the theory sample frequency
Ratio F1:F2 is updated, then in each preset time period in detected heart rate data group and acceleration information group
Ratio data more meets updated sample frequency, equally can be directly according to updated when carrying out Dynamic Heart Rate calculating
Theoretical sample frequency ratio chooses the heart rate data and acceleration information of corresponding number, can either guarantee as few to acceleration as possible
Degree evidence is modified, and can further improve the accuracy of Dynamic Heart Rate data calculating.
Optionally, in the another specific embodiment of the application, can further include:
If the acceleration information number ratio a in the heart rate data number and acceleration information group in heart rate data group is not
Equal to F1:F2；
In the preset time for then judging predetermined quantity, whether the difference between ratio a and F1:F2 is greater than preset difference value, and
Preset difference value is non-constant, then output data detects failure.
As mentioned previously, because the duration of preset time period needs rationally to control, then for preset time period in setting
The heart rate data number of interior detection and the ratio of acceleration information number can't differ too with the ratio of theoretical sample frequency
Greatly, if in the case where the time span of preset time period is sufficiently small, the difference between ratio a and F1:F2 is still very
Greatly, then illustrate that photoplethaysmography or acceleration transducer largely have failure, user can be reminded to carry out in time
Maintenance.
