Specific implementation mode
The application is described in further detail with reference to the accompanying drawings and examples.It is understood that this place is retouched The specific embodiment stated is used only for explaining related invention, rather than the restriction to the invention.It also should be noted that in order to 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 The process of pass is the committed step of system research.But process is numerous in thermoelectricity production, the attribute for participating in calculating is very more, profit It is too low with traditional association rules mining algorithm acquisition correlation rule efficiency, it calculates knowledge that is complicated and obtaining and is not easy to directly quilt User understands, therefore it is proposed that the influence relationship of each inter process in producing, pass is indicated in the way of state relation chain The representation method of connection chain is embodied in boiler parameter, and such as No. 1 furnace gas packet pressure decline leads to No. 1 stove main vapour pressure lower-left drop, into And lead to No. 1 burner hearth differential pressure lower-left drop, lead to No. 1 stove feed pressure upper left liter.It, can be big by being associated with chain as acquisition Key node is found in amount production process to be regulated and controled, and the result of target process is quickly directly affected.It is with hot water boiler system Example is contributed by being associated with link analysis in order to improve boiler hot, can be by increasing primary air fan power, reducing overfire air fan gear Plate aperture keeps that the amount of delivering coal is constant reaches target.State relation chain shows " rising ", " decline " and " constant " three kinds of states, And intuitively show very much the front-to-back effect relationship between multiple working procedure states.
By obtaining state relation chain, the strongest most strong association chain of relevance is found out, by with the modeling of next stage, to The more intuitively relationship between display and adjustment each process.
The foundation of S4, prediction model:
This part primarily directed to working obtained state relation chain and processed data are modeled above.With FNT (flexible Neural Tree) method obtains modeling and forecasting formula, realizes the prediction to process data.
1) database table that modeling is used has, and by pretreated tables of data, FNT user's table, FNT operating parameters table, surveys Try tables of data, training data table, association chained list, output result table etc..It is carried out by the result obtained to the processing of data before Interative computation.
2) for coal-burning boiler parameter, crucial flow and corresponding production input and output parameter are found, by it It is input in FNT, obtains the output function shaped like formula (8), An and Bn are the ginsengs after two groups of PSO (particle cluster algorithm) optimization Number, netn are the tree structures after PIPE (pipeline is used for the communication between affiliation process) optimization;Pass through the letter Several variations to future production carry out forecast analysis.
3) by running FNT algorithms.Constantly modification iterations, obtain best iterations.In returning the result Standard average variance (NMSE) value, to determine trained effect accuracy.By obtained formula, with matlab (matrix experiments Room) preliminary figure forecast analysis is carried out, by comparing the final accuracy for determining prediction.
The effect of modeling and forecasting is to carry out science to the association attributes for influencing target process on the basis of state relation chain It calculates, obtains the variation tendency formula of measuring point data, industrial processes are simulated, the correlation based on current production status The production status of parameter prediction a period of time in future, to which auxiliary direction enterprise adjusts production procedure parameter, the step for be real The now key to the application of auxiliary production process prediction adjustment and the most important content of Project-developing.By to second It is mitogenetic at state relation chain modeled, will be associated with chain in the other processes in addition to last as the defeated of anticipation function Enter value, and target process, by changing the value of other processes, can predict target process in a timing as function-output Between after numerical value, so as to be optimized in advance to production procedure.It is embodied in thermoelectricity production process, equally with hot-water boiler For, previous step has obtained association chain:Primary air fan power rise → overfire air fan baffle opening declines → and the amount of delivering coal is constant → heat, which is contributed, to be improved, and in modeling and forecasting, it is function-output, primary air fan power, overfire air fan baffle opening, pot that heat, which is contributed, The stove amount of delivering coal is function input value, then can obtain the prediction technique as shown in formula (9).
