Embodiment
Below in conjunction with the accompanying drawings and the invention will be further described by specific embodiment, and following examples are descriptive
, it is not limited, it is impossible to which protection scope of the present invention is limited with this.
Check method during a kind of on-line operation intelligent calorimeter, this method concretely comprise the following steps：
(1) intelligent calorimeter cluster is installed to form tree topology, can remotely obtain in the intelligent calorimeter cluster
Summary table and each point of flow-meter data, obtain the flow conservation basic model of the intelligent calorimeter cluster；
(2) the tree topology formed according to intelligent calorimeter cluster, virtual tributary dynamic corrections intelligent calorimeter is introduced

(6) result of calculation is modified and Evaluation of Uncertainty；
(7) current Time Duration Error and initial error are contrasted, evaluation is verified during progress.
The cluster formed after intelligent calorimeter installation has tree topology.Therefore about fixed in flow conservation, the same period
The actual flow increment of interior summary table is equal to the actual flow increment sum of each point of table.Because actual flow increment can be with reading increment
Represented with relative error, therefore an equation comprising all meter reading increments and relative error can be obtained.If it is known that
The relative error (can be detected and obtained by single table) of any one instrument is using the relative error of other instrument as not in cluster
The amount of knowing, and notice the quantity that by increasing measurement period equation can be made to meet or exceed unknown number, then it can pass through
Solve the relative error that equation group determines other instrument.The autonomous type algorithm is missed by the mutual contrast conting of cluster internal instrument
Difference, without external perimysium reference instrument.
When tree topology pipeline, which exists, to be leaked, it is necessary to which equation group is modified.In flow measurement, leakage is shown as
Pipeline leak, TEMP consume and calorimeter power consumption.In the method, the lossy load for being considered as virtual tributary,
And introduce Virtual Intelligent calorimeter.Using the parameter measurement function of intelligent calorimeter, loss correction item is determined.Provide revised
Algorithm flow and simulation result.
It is specific decomposable process below
For the ease of clearly describing this method, provide be defined as below first：
Stream：Flow in or out a certain occluding surface S scalar (shown in Fig. 2 arrows).It is negative to flow into just, to flow out.Convection current
Do following agreement：Stream will not be accumulated and any moment is in compliance with law of conservation.I.e. through any enclosed curved surface S current algebra and wait
In zero.Stream is with the integer mark since 0.
Broad sense flow：Abbreviation flow, flow the integration to the time.Flow conservation can be released by stream conservation.That is random time
In section, the flow increment algebraical sum through occluding surface S is equal to zero.
Intelligent calorimeter：Abbreviation flow instrument or flowmeter (M in Fig. 20~M4), record the corresponding instantaneous delivery flowed.Flow
Meter is with MjMark, j are the numbering of corresponding stream.
Cluster：Through the set of the flow instrument corresponding to a certain occluding surface S all streams.
Meter reading：Obtain the reading of all instrument in a certain moment cluster.In logic, it is identical should to return to each instrument for meter reading action
The reading at moment.If but in fact, each meter reading return time interval it is short enough, be regarded as mutually in the same time.
Measurement：One-shot measurement is the meter reading twice to cluster certain interval of time, the result is that the increasing of front and rear reading twice
Amount.
First, flow conservation ideally：
Relative error δ：
Wherein x is the actual increment by the flow of certain instrument in a period of time, and y is the instrument in the same period
The increment of reading.
Certain occluding surface S defines flow instrument cluster AS={ Mj| stream j passes through occluding surface S }, flow instrument in cluster
Number NS=n.If flowmeter MjIth measurement result is yij, corresponding actual value is xij.Wherein i=1,2 ..., m, m
For pendulous frequency.Had according to flow conservation agreement
If δjRepresent flowmeter MjRelative error, then by definition save relative error definition can obtain
(2) formula is substituted into, is hadSet up.Without loss of generality, it is assumed that δ0, it is known that then have
Order
(3) formula of substitution has
(5) formula can be write as matrix form
Y ε=- η (6)
Wherein
yiFor instrument M1~Mn-1The result vector of ith measurement.
ε=(ε1 ε2 … εn-1)T, η=(y1,0ε0 y2,0ε0 … ym,0ε0)T。
(6) formula shows, if in known cluster a certain instrument relative error δ0, then multigroup survey of all instrument can be passed through
Amount result extrapolates the relative error δ of other each instrumentj, j=1,2 ..., n-1.
2nd, virtual tributary computed losses are added：
Loss (intelligent calorimeter loss, leakage loss, line resistance loss etc.) be present in actual intelligent calorimeter cluster,
We introduce the concept of virtual tributary, instead of the loss value sum being the theme in problem with line loss.The branch road includes virtual
Intelligent calorimeter and dummy load.Cluster total losses can be equivalent to the energy consumption of dummy load.In figure 3, imaginary occluding surface S
An intelligent calorimeter cluster is defined, intelligent calorimeter is with symbol Mj(j=0,1 ..., n) represent.MnFor Virtual Intelligent heat
Table.Agreement flows into S energy as just, it is negative to flow out.
It is located at ith measurement period TiInside flow through MjElectric energy be xi,j(i=1,2 ..., m, to identify each measurement period
Sequence number；M is pendulous frequency), then following formula establishment is had according to law of conservation of energy.
It has been generally acknowledged that in the ith measurement period, MjReading increment yi,jWith xi,jWith following relation.
yi,j=(1+ δj)xi,j (10)
(10) in formula, δjFor Mj(average) relative error.If order
Then (11) formula can turn to
Without loss of generality, it is assumed that known M0Relative error δ0, so as to understand ε0.Provide Virtual Intelligent calorimeter MnPhase
To error deltan=0, so as to there is εn=1 and xi,n=yi,nSet up.Therefore (2-22) formula turns to
3rd, the expression being lost in virtual tributary
(13) Section 3 x in the left side in formulai,nRepresent measurement period TiThe energy consumption (the total loss of cluster) of interior dummy load,
(17) formula and (19) formula equation group are all energy conservation equation group.They show on the premise of the conservation of energy, if known cluster
The relative error δ of interior a certain instrument0, it is likely that pass through multigroup measurement result yi,jExtrapolate other all intelligent calorimeters
εj, and then obtain relative error δj(j=1,2 ..., n-1).In actually calculating, the outflow of virtual tributary is cluster summary table M0's
Reading increment subtracts each point of table MjThe sum of (j=1 ..., n), and this value is multiplied by a loss system judged by empirical value
Number.Energy loss of the loss factor as intelligent calorimeter cluster, tried to achieve by loop iteration method described below.It is right
This, after adding virtual tributary, equation respective change isα is amendment experience, is
A range of random value.
Data screening：
This method from power information acquisition system firstly the need of intelligent calorimeter correlation meter reading data is obtained, by filling up
Missing data, abnormal data, smooth noise data are eliminated, and correct inconsistent data, remove noise, filling sky in data
Value, missing value and processing inconsistent data, so as to obtain valid data.
We need to obtain the measurement result of all meters in whole tree-structured system first, and measurement together has not
In the case of deterministic, we can more acquisition data as far as possible, to ensure the accuracy of the result under rational calculation error
With completeness requirement.Data volume minimum should add one not less than ammeter quantity.Data screening has the following steps：1. real-time inspection.
2. integrity checking and missing values processing.3. method for visualizing notes abnormalities, the orthogonality of data 4. is examined
Real-time inspection：Whether we check same group of meter meter reading value in same time point copy reading.If it is unsatisfactory for this
It is required that data can not use.
Data integration：Data integration is on the basis of original meter reading data, and intelligent calorimeter meter reading data is added to
In the meter history meter reading data.
Integrity checking and missing values processing：We need to carry out integrity checking to data first.Integrity checking
Groundwork is missing values processing.For missing values processing, traditional method has direct deletion, or utilizes average value, intermediate value, divides
Digit, mode, random value etc. substitute.It is general so to do effect, because being modified equal to people to data.The side that we use
Method gives a forecast model to calculate missing values by history error and other margins of error, is added to after calculating missing values in algorithm and carries out
Whether secondary checking, judging the situation of missing values can meet that missing requires.Specifically, if in one group of data missing values compared with
More, missing amount is excessive, and we directly can fall the rejection of data, because if larger noise can be produced by introducing, result is caused
Harmful effect.Empirically value judges, if missing values are more than 10%, we are more likely to wait more meter reading datas.If energy
Meet to require, missing gathered data Intelligent heat quantity meter reading is added in the power consumption of virtual tributary by we first, uses original
Model computational intelligence calorimeter error condition.If data added to virtual tributary renewal after result of calculation be maintained at zone of reasonableness it
Interior, we are further according to the average line loss experience accounting of the taiwan area, and deduction line loss is filled to data from the electricity of virtual tributary.
After filling, error condition is recalculated using the form of filling, if meet twice other meters change less and missing meter with
The little condition of history calculated value deviation, it is correct that we are considered as the filling of its result.
Without loss of generality, we are not less than n-1 using missing values intelligent calorimeter as a Virtual table in pendulous frequency m
In the case of, write (14) formula as matrix form
Y ε=- η ' (15)
WhereinyiFor ith measurement result vector；ε=(ε2 ε3 …
εn-1)T；η '=η-y·1=(y1,0ε0-α(y1,0x1,n)-y11 y2,0ε0-α(y2,0x2,n)-y12 … yn-1,0ε0-α(y1,0xn-1,n)-
y1n)T.By mentioned earlier, similarly equation (15) can solve.If ε=(ε2 ε3 … εn-1)TMeet the requirement, then equation closes
Reason, recovers the result according to virtual tributary value.
Data analysis notes abnormalities data (by visualization tool)：Using the daily meter reading data of intelligent calorimeter as one
Vector, then multigroup copy reading can form a Vector Groups.In multidimensional data analysis technology, by by each vector visualization
Represent, therefrom find out the special vector changed extremely.Using CrystalAnalysis visualization tool method, it can be found that
The special point value that peels off, special analysis are done to this point value, further enhance data monitoring, optimize core data.In addition, utilize cluster
Algorithm analyzes the vector clusters, as a kind of special discovery method to be noted abnormalities in visable representation in data basis.
Orthogonality is examined：Error analysis algorithm requires there is weak dependence between each equation of equation group, and otherwise equation group is in disease
State causes error calculated to exceed tolerance interval.When meeting enough requirements, equation can just calculate.
Computational methods：Intelligent heat quantity Watch Error iterative calculation method based on uncertainty of measurement
What it is due to this method measurement is intelligent calorimeter mean error interior for a period of time, and the result of measurement is simply measured
Estimate, the uncertain factor in measurement process can cause the uncertainty of measurement.Repaiied for known systemic effect
The estimate that measurement result after just is still simply measured, considers Evaluation of Uncertainty method, and guarantee makes incomplete preferable
Reproduction or representativeness of sample not enough wait in the case of, measure still can reflect truth.
Iterative method is a kind of process being constantly newly worth with the old value recursion of variable, and iterative algorithm is a kind of base solved the problems, such as
This method.Its basic thought is to release the new value of its one from the initial value of variable.In our method, iteration is applied to pair
Virtual circuit amendment experience α estimation.
Provide hypothesis first herein：The quantity of the overproof table of error is less than the 5% of summary table quantity in a taiwan area, is me
Think the reliability of measurement instrument 95%.
In general, the reliability of measurement instrument can be increased over time and reduced, therefore for the ratio in difference
Taiwan area we perform the calibrating reliability objectives scope of floating.Fig. 4 is Measurement reliability and the change schematic diagram of time.According to platform
The average usage time length situation of meter in area, we are modified to the value.
Our method is summarized as follows：In the case of given initial experience value α=0, computational intelligence calorimeter cluster
Error condition, if the result of calculation meets confidence level requirement, that is, the overproof intelligent calorimeter quantity calculated is less than prescribed limit
Interior, then the algorithm terminates.Otherwise α value section is adjusted upward, returns to Algorithm for Solving.
Joint Evaluation of Uncertainty method：
Mathematical modeling:δ=1/ (Y-1η)-1
Due to Y, η meets independence, then has：
So we have joint expanded uncertainty U=kucK=2 is taken, is had：
If the Intelligent heat quantity Watch Error solved meets actual desired, independent repeated measures then are carried out to being measured, are passed through
A series of resulting measured values, experimental standard deviation s (x) is obtained with statistical analysis technique, when being used as quilt by the use of arithmetic mean of instantaneous value
When measuring estimate, the uncertainty of estimate is measured by calculating：
Using Bessel Formula method, it is measured independent repeated measures n time to same under the conditions of repeatability, obtains n and survey
