Below with reference to the accompanying drawings the processing method and processing device of fetal heart rate curve data according to an embodiment of the present invention is described.
Fig. 1 is the flow chart according to the processing method of the fetal heart rate curve data of one embodiment of the invention.Wherein, it needs
Illustrate, the processing method of the embodiment fetal heart rate curve data is applied in the processing unit of fetal heart rate curve data, should
The processing unit of fetal heart rate curve data is located in fetal monitor.
As shown in Figure 1, the processing method of fetal heart rate curve data according to an embodiment of the present invention, includes the following steps.
S1 obtains the fetal heart rate curve data in the monitoring period.
Specifically, fetal heart rate data can be acquired by ultrasonic probe after fetal monitor starting, and the data of acquisition is put
Enter appointed buffer.
The embodiment of the present invention guards all fetal heart rate curve data in the period from acquisition in buffer area.
S2 determines first effective fetal heart rate data and the last one effective fetal heart rate data in Fetal Heart Rate rate curve data
Position.
In one embodiment of the invention, first effective fetal heart rate data and most is determined in Fetal Heart Rate rate curve data
The process of the position of the effective fetal heart rate data of the latter, as shown in Fig. 2, may include:
S21 marks the wrong data in fetal heart rate curve data.
Wherein, the mode wrong data in fetal heart rate curve data being marked has very much, can be according to actually answering
With being selected, the present embodiment to this with no restriction, in order to more clearly illustrate to mark in fetal heart rate curve data
The process of wrong data, is illustrated below:
Mode one: the maximum fetal heart rate data of probability of occurrence in fetal heart rate curve data is determined, and most by probability of occurrence
Big fetal heart rate data is as reference data, then, the first value range of valid data is determined according to reference data, later,
It is mobile to the head and the tail both ends of fetal heart rate curve data respectively since the position of the maximum fetal heart rate data of probability of occurrence, and judge
Whether corresponding fetal heart rate data is within the first value range, if judging corresponding fetal heart rate data not in the first value model
Within enclosing, then corresponding fetal heart rate data is labeled as wrong data；If judging corresponding fetal heart rate data in the first value
Within the scope of, then the value range of valid data is redefined according to corresponding fetal heart rate data, and take based on what is redefined
Value range judges next fetal heart rate data, until analyzing first or the last one fetal heart rate data.
Wherein, it should be noted that it is general to occur that there are the fetal heart rate datas on multiple positions in fetal heart rate curve data
The maximum fetal heart rate data of rate, that is, the maximum fetal heart rate data of probability of occurrence in fetal heart rate curve data there are multiple positions,
It can be mobile to the head and the tail both ends of fetal heart rate curve data respectively since any one position in multiple positions.
Wherein, it should be noted that valid data are the true Fetal Heart Rate of fetus.
Specifically, can be looked for by the method for probability statistics after obtaining the fetal heart rate curve data in the monitoring period
The maximum fetal heart rate data of probability of occurrence in fetal heart rate curve data out, and using the maximum fetal heart rate data of probability of occurrence as base
Quasi- data, then, according to the first value range of reference data and default value construction valid data.
Wherein, default value is pre-set for constructing required for the value range of valid data in fetal monitor
Numerical value, for example, default value can be 20,30 or 35 etc..
For example, it is assumed that default value 20, and determine in the fetal heart rate curve data in the monitoring period and occur generally
The maximum fetal heart rate data of rate is 120 beats/min, then is configured with according to the maximum fetal heart rate data of probability of occurrence and default value
The value range for imitating data is 100-140 beats/min.
It is maximum from probability of occurrence after according to reference data and the first value range of default value construction valid data
The position of fetal heart rate data starts respectively to the movement of the head and the tail both ends of fetal heart rate curve data, and judges corresponding fetal heart rate data
Whether within the first value range, if judging, corresponding fetal heart rate data not within the first value range, will be corresponded to
Fetal heart rate data be labeled as wrong data, and continue according to the first value range to next fetal heart rate data whether effective
Judged within the value range of data；If judge corresponding fetal heart rate data within the first value range, basis
Corresponding fetal heart rate data redefines the value range of valid data, and based on the value range redefined to next tire
Heart rate data is judged, until analyzing first or the last one fetal heart rate data.Tire can be accurately marked as a result,
Wrong data in heart rate curve data.
For example, it is assumed that the fetal heart rate data in fetal heart rate curve data is total up to 5, and first fetal heart rate data
For 120 beats/min, second fetal heart rate data be 130 beats/min, third fetal heart rate data is 120 beats/min, the 4th
Fetal heart rate data is 150 beats/min, and the 5th fetal heart rate data is 135 beats/min, default value 20, the of valid data
One value range be 100-140 beats/min, and the maximum fetal heart rate data of probability of occurrence be 120 beats/min, herein, with from
It is mobile to the head and the tail both ends of fetal heart rate curve data for third fetal heart rate data, from third fetal heart rate data to first
During a fetal heart rate data is mobile, it can determine that second fetal heart rate data in the first value range is 100- by comparing
140 beats/min, at this point, can be reconstituted according to the second fetal heart rate data valid data out value range be 110-150 times/
Minute, and judge whether first fetal heart rate data be effective, passes through ratio with 110-150 beats/min of value range rebuild
First fetal heart rate data can relatively be determined also within 110-150 beats/min, therefore, first fetal heart rate data is effective
Data.In the process mobile to the 5th Fetal Heart Rate from third fetal heart rate data, the 4th Fetal Heart Rate can determine by comparing
Data are not in the first value range, at this time, it may be determined that the 4th fetal heart rate data is wrong data, and by the 4th Fetal Heart Rate
Data are marked for wrong data, then, continue to lead to judge the 5th fetal heart rate data in the first value range
Cross compare can determine the 5th fetal heart rate data in the first value range, at this time, it may be determined that the 5th fetal heart rate data is to have
Imitate data.Thus, it is possible to find out, the 4th Fetal Heart Rate in fetal heart rate curve data can be gone out with accurate marker by the above method
Data are wrong data.
Wherein, it should be noted that it is only to be illustrated by taking five fetal heart rate datas as an example in the embodiment,
In practical application, it should be subject to actual fetal heart rate curve data.
Mode two: it determines the average value of the fetal heart rate data in fetal heart rate curve data, and is determined effectively according to average value
Then second value range of data for each fetal heart rate data in fetal heart rate curve data, judges corresponding Fetal Heart Rate
Whether data are within the second value range, if it is not, corresponding fetal heart rate data is then labeled as wrong data.
Specifically, fetal heart rate curve data can be calculated after obtaining the fetal heart rate curve data in the monitoring period
Average value, then, according to the average value and default value construction valid data the second value range.
Wherein, default value is pre-set for constructing required for the value range of valid data in fetal monitor
Numerical value, for example, default value can be 20,30 or 35 etc..
For example, it is assumed that default value 20 calculates being averaged in the fetal heart rate curve data in the monitoring period
Value is 125 beats/min, then is 105-145 beats/min according to the value range of average value and default value construction valid data.
The embodiment of property as an example takes according to the second of the average value and default value construction valid data
Be worth range after, can since first fetal heart rate data in fetal heart rate curve data, judge each fetal heart rate data whether
Within second value range of valid data, if it was not then thinking that corresponding fetal heart rate data is wrong data and marks
Come, otherwise it is assumed that being valid data, then moves on the position of next fetal heart rate data up to fetal heart rate curve data
Until the last one fetal heart rate data.Accurate marker goes out the wrong data in fetal heart rate curve data as a result,.
Mode three: all wrong data present in fetal heart rate curve data are marked by step S11-S12.Wherein,
S11, judge that whether absolute difference is in default value between i-th of fetal heart rate data and i+1 fetal heart rate data
In range.
S12, if it is not, i-th fetal heart rate data is then labeled as wrong data.
Wherein, i is the positive integer more than or equal to 1, and less than N, wherein N is the fetal rhythm in fetal heart rate curve data
The total number of rate data.
The embodiment of property as an example is obtaining to sequentially determine whether fetal heart rate data is wrong data
After taking the fetal heart rate curve data in the monitoring period, it can sentence since fetal heart rate curve data first fetal heart rate data
Whether the absolute difference of disconnected first fetal heart rate data and second fetal heart rate data is in default value range, if it is, really
Fixed first fetal heart rate data is valid data, if it is not, then first fetal heart rate data is labeled as wrong data, so
Afterwards, then the absolute difference of second fetal heart rate data and third fetal heart rate data is analyzed whether in default value range, if
It is then to confirm that second fetal heart rate data is valid data, if not then by second fetal heart rate data labeled as error number
According to；And so on, until the last one fetal heart rate data of fetal heart rate curve data.
Wherein, it should be noted that the method for this marked erroneous data is realized simple, high-efficient.
S22 is searched backward since first fetal heart rate data in fetal heart rate curve data, until finding first
It is not labeled as the fetal heart rate data of wrong data, and found first is not labeled as the Fetal Heart Rate of wrong data
Data are as first effective fetal heart rate data, and found first are not labeled as the Fetal Heart Rate of wrong data
Position of the position of data as first effective fetal heart rate data.
Wherein, it is to be understood that during first fetal heart rate data starts to search backward, if do not find not by
Labeled as the fetal heart rate data of wrong data, then illustrate that all fetal heart rate datas are mistake in analyzed fetal heart rate curve data
Accidentally data, at this point, setting invalid value for the position of first effective fetal heart rate data.
S23, the Look-ahead since the last one fetal heart rate data in fetal heart rate curve data, until finding first
A fetal heart rate data for being not labeled as wrong data, and found first is not labeled as the fetal rhythm of wrong data
Rate data are as the last one effective fetal heart rate data, and found first are not labeled as the tire of wrong data
Position of the position of heart rate data as the last one effective fetal heart rate data.
Wherein, it is to be understood that during the Look-ahead since the last one fetal heart rate data, if not finding
It is not labeled as the fetal heart rate data of wrong data, then illustrates that all fetal heart rate datas are equal in analyzed fetal heart rate curve data
For wrong data, at this point, setting invalid value for the position of the last one effective fetal heart rate data.
S3 is clear by the fetal heart rate data before being located at the position of first effective fetal heart rate data in fetal heart rate curve data
It removes.
The embodiment of property as an example can determine whether the behind the position for obtaining first effective fetal heart rate data
Whether the position of one effective fetal heart rate data is invalid value, if it is not, then first will be located in fetal heart rate curve data effectively
Fetal heart rate data before the position of fetal heart rate data is removed, that is, removing has from first fetal heart rate data position to first
Imitate all fetal heart rate datas of the previous fetal heart rate data position of fetal heart rate data.
Wherein, it is to be understood that removing from first fetal heart rate data position to first effective fetal heart rate data
Previous fetal heart rate data position all fetal heart rate datas after, first effective fetal heart rate data is fetal heart rate curve
First fetal heart rate data of data.
The embodiment of property as an example, if judging, the position of first effective fetal heart rate data is invalid value,
Then determine that all data are wrong data in analyzed fetal heart rate curve data, at this point, can be to should not fetal heart rate curve number
According to being handled, effective fetal heart rate data is continued waiting for.
The embodiment of property as an example is judging that the position of first effective fetal heart rate data is not invalid value
When, can further judge first effective fetal heart rate data whether be fetal heart rate curve data first fetal heart rate data, such as
Fruit first effective fetal heart rate data is first fetal heart rate data of fetal heart rate curve data, that is, first effective Fetal Heart Rate
The position of data is equal to the position of the first fetal heart rate data of fetal heart rate curve data, it is determined that the head end of fetal heart rate curve data does not have
Wrong data do not need to remove.
If first effective fetal heart rate data is not first fetal heart rate data of fetal heart rate curve data, that is, first
The position of a effective fetal heart rate data is not equal to the position of the first fetal heart rate data of fetal heart rate curve data, then removes from first
All fetal heart rate datas of the fetal heart rate data position to the previous fetal heart rate data position of first effective fetal heart rate data.
It further,, can be in new first fetal heart rate data after removing head end wrong data in order to prompt user
Position automatically generate a mark, to inform that user is to have done data-cleaning operation automatically herein.
Wherein, it is to be understood that above-mentioned to be located at the in fetal heart rate curve data during entire fetal heart monitoring
