Convenient for description, is illustrated only in attached drawing and invent relevant part.
It should be noted that in the absence of conflict, the features in the embodiments and the embodiments of the present application can phase
Mutually combination.The application is described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The present embodiment provides a kind of manufacturing parameter Optimization Prediction methods, including the following contents:
The acquisition of S1, monitoring data:Has the characteristics that typical flow object in the monitoring data of thermoelectricity production field, entirely
Production technology includes multiple front and back concerned process steps or process, all deploys OPC data acquisition interface in these processes, can incite somebody to action
In real-time detector data storage to database;And different production systems, such as hot-water boiler change water system, auxiliary system, deposit respectively
It in different subsystems, does not interfere, and is finally integrated into total Database between each other, these collected data are for we
Forecast analysis provide the foundation.
The pretreatment of S2, monitoring data:
(1) data integration and data filling,
Data integration:The problem of disperseing for data, data are integrated, chooses all process steps and be in same time piece
The data of section, merging becomes new data.The data obtained at this time contain the information of a large amount of processing flow sequences, are carried out to data
Accurate result can be obtained when processing flow sequence mode excavation.
Control filling:
For the data of a large amount of blank, directly given up to fall;For the data of a small amount of blank, there is the use of visible trend
Arithmetic progression completion method, the use averaging method for not having visible trend are filled.By being filled to clear data, to protect
Demonstrate,prove the stability of data.Prevent influence of the null value to result in later stage modeling and forecasting.In flow object χ, if a certain process
XiContaining excalation value, the data of missing time section are { Xi(tm),Xi(tn) between data, then the missing data contains altogether
There are n-m-1, j-th of missing values in this section are
If the data do not have tendency feature, filled up using averaging method, the data of filling up in this section are
Wherein, Xi(tj) it is Xi(tm) before n-m data, Xi(tk) it is Xi(tn) after n-m data;If vacancy
Value then directly deletes it in the above or below of data;If Xi(tm) front or Xi(tn) subsequent data less than n-m, then from
Xi(tn) below or Xi(tm) front is postponed, and to choose total amount be 2 (n-m) a data, the mean value ensured contains enough information,
And select data volume excessive, it will increase computation complexity;Data volume is very few, and is not enough to include the information of data.
(2) sequential adjusts,
We regard the sampled data of each process as time series (TimeSeries) data, final purpose are
The relationship that influences each other between different processes is calculated, this requires the data between process are corresponded according to influence relationship
's.However, every record in database includes the sampled data of synchronization difference process, this is not to be closed according to influence
It is corresponding, this just needs us according to the relative delay of process to be adjusted, namely according to relative delay pair
Process data carry out Forward or rear shifting.
The data of each process are the time series of a constant duration, namely are arranged according to chronological order
The sampling value set of row.Influence between different processes constitutes between its corresponding two time series
Two time serieses of delay correlation pair, which carry out delay correlation analysis, can acquire the sequential Pearson of two-step
Related coefficient is used for weighing the linearly related degree of two sequences, and definition is as shown in formula (3).
Wherein,WithIt is the average value of sequence sum respectively.The absolute value of related coefficient is bigger, and correlation is stronger;Phase relation
For number closer to 0, correlation is weaker.It is made of Pearson correlation coefficient of two time serieses under the different delays time
Curve, we term it Pearson correlation coefficient curves.Related coefficient curve illustrates two time serieses with delay time
Increase, the variation tendency of correlation.The extreme point of curve namely the point of correlation maximum, usually characterize two time serieses
It is influenced according to the delay time.Prolonging based on Pearson correlation coefficient curve is carried out to the time series data of two-step
Slow correlation analysis draws related coefficient curve, prolongs the corresponding length of delay of related coefficient maximum value as the opposite of two-step
The slow time.To be adjusted to process.
(3) process clusters
Numerous discrete data states will greatly increase the time complexity of subsequent association analysis, and clustering can help
We reduce the discrete state number of data, us is made only can targetedly to represent almost institute with K a small number of classifications
There are data.We are clustered using K-Means algorithms, and cluster is individually carried out for each process namely each process
All there are one cluster number K and K corresponding types, and the cluster number K of different processes may be different.K when for cluster
The determination of value, we use is carried out based on the silhouette coefficient method of condensation degree and separating degree.Each process data are clustered
Later, it will obtain K classification, final we will replace all process data, subsequent association point using this K classification
Analysis will be based on cluster about subsequent process data and carry out.The paralell design of the K-Means algorithms based on data parallel is given below:
Input:The time series data of a certain process, cluster number K
Output:The cluster result of the process data
1) K cluster centre of random initializtion, and it is broadcasted each calculate node;
2) for each data of each subregion, they are referred to cluster centre institute's generation away from nearest neighbours one by one
The cluster classification of table;
3) the sum of the sum of data of same cluster classification and number are calculated for the data of each subregion, and by it
Be collected into driver nodes, the cluster centre of next iteration is recalculated in driver nodes;
4) if cluster centre no longer changes or reached specified iterations, algorithm performs terminate;Otherwise, will
New cluster centre is broadcast to each calculate node, then turns to step 2).
K-means algorithms control iterations using the minimization of object function criterion, for numeric type data, usually adopt
Use Euclidean distance (Euclidean Distance) as object function.Equipped with two data object X1And X2, EUCLID (X1,
X2) it is X1And X2Euclidean distance, E be all objects square error summation, each object contain t variable, then two
Euclidean distance between object is square root sum square of the difference of t variate-value of two objects, i.e.,
Object function form is square error criterion function
Wherein, CiFor arbitrary cluster set, X CiIn object, miFor class CiMean value.Distance metric in object function
Other modes, such as manhatton distance, Chebyshev's distance, Hamming distance, power distance and mahalanobis distance etc. can also be used.It is false
If arbitrary process XiPreferable clustering number mesh be Ki, the cluster set that is obtained after being clustered according to the preferable clustering number mesh.
S3, the discovery for being associated with chain:
The characteristics of by analyzing Apriori Rule Extraction processes, obtains state using it and closes
Join the algorithm of chain.Under the conditions of meeting technological process, using association rule algorithm between the dimension based on Apriori, obtain
To correlation rule between the class of any two process.By rule between any two, numerous associations is obtained.
1) correlation rule between class:According to the demand of flow object, minimum support min_sup, min confidence are set
Min_conf is closed carrying out the dimension based on Apriori (rule association algorithm) to the cluster data of the arbitrary two-step of cluster set
Join rule digging, search for frequent 2- predicates collection, generates the binomial correlation rule between different arbitrary two clusters of process, these rule lists
Show that two of different processes meet the relationship between minimum support and the cluster of min confidence.In boiler parameter, we
Carry out materialization description, preceding paragraph XiConsequent is XjAll cluster data collection common properties give birth to 2 cluster association rules, preceding paragraph Xj
Consequent is XiAll cluster data collection common properties give birth to 1 cluster association rule.
2) process is associated with:If any two process XiAnd XjCluster between common property give birth to ωijRule, wherein any one rules and regulations
It is then ia → jb.Since interest-degree I (ia → jb) sizes are different to the meaning of correlation rule, signed magnitude is used to calculate herein
Preceding paragraph is XiWith consequent for XjCluster between degree of association cij(β), then
cij(β)=Sβ(ia→jb)×I'β(ia→jb),β≤ωij (6)
Wherein, β indicates the β rules in strictly all rules, and
I'β(ia → jb)=Iβ(ia→jb)-1 (7)
By conversion, the association between process is clustered is converted to the association of inter process, obtains the associated relationship of process.
3) it is most associated with chain and state relation chain by force:Any two inter process correlation rule and its association are known at present
Degree, according to the relationship between item before and after the data, selection meets time series L={ X '1,X'2,…,X'nAnd degree of association maximum
Data be associated, a most association chain by force can be constructed, when which illustrates in flow object that all process steps are run on chain
A kind of influence relationship.Finally obtain most strong association chain all in historical data.In order to preferably utilize above-mentioned association analysis
As a result, and make it easier to be used in actual production with aid decision, by the state of process, (for example monitoring data is upper for we
Liter, decline or invariant state) further it is combined with incidence relation, show that the state relation relationship between process, i.e. state are closed
Join chain.
Association analysis:Association analysis (Association Analysis) includes mainly correlation rule (Association
Rule it) generates and is associated with chain/tree (Association Chain/Tree) generation.In association rule mining, we just for
Correlation rule is generated between two two-steps, and association chain/tree is finally generated by the correlation rule of two two-steps.In process cluster numbers
According to upper 2 correlation rules, and the rule generated according to ordered pair when process are found out using Apriori classical correlations rule mining algorithms
Then it is filtered.
State relation:In order to preferably using above-mentioned association analysis as a result, and making it easier to be used in actual production
With aid decision, we by the state (such as up and down or invariant state of detection data) of process further be associated with
System is combined, and obtains the state relation relationship between process, we term it operating status knowledge bases.Operating status knowledge base can
For in the industry auxiliary such as fault detect and early warning, parameter regulation.State relation can use the method counted to obtain, more
Simply.
In the research of this method, it can be found from mass data and the close phase of optimization aim using association rule algorithm
