Description
Technical field
The invention belongs to engineering design integration of information system and isomery multi-data source bridging technology field, particularly a kind of towards the integrated parameter mapping method (Design Parameter Mapping Method) of the multidisciplinary design of complex equipment (Multi-Disciplinary Optimization Design) software.
Background technology
Large Complex Equipment has very important effect to the economic construction and the national defense construction of country, also is the mainstay industry that China gives priority to.Typical Large Complex Equipment comprises aviation aircraft, aeromotor, genset, performing comprehensive coal mining unit, naval vessel and armament systems etc.Great deal of research results shows that the design process of equipment has directly determined performance, quality, production cycle, the cost of equipment suitable with maintaining method etc.Therefore, the organization and management design process is the key problem of Large Complex Equipment development effectively, obtains showing great attention to of academia and industrial community.
The Large Complex Equipment design process relates to the multidisciplinary synthesis optimization problem, and numerous slip-stick artists from the different technologies field finish the engineering calculation task of related discipline respectively.The design engineer adopts a large amount of engineering parameters such as dynamics, thermodynamics, fluid mechanics, structure and electronics of many engineering design software repeated calculation.The slip-stick artist need handle a large amount of inputoutput datas, and the two and three dimensions figure.
In the complex equipment design process, the software for calculation of each subject all is an independent executable program, some program is that designing unit is independently developed, some program is the exploitation of professional software company, the software isomerism is very big, and these software for calculation all adopt processor-oriented Programming Methodology to realize there is not User Interface.We find that most of multidisciplinary software for calculation all is to adopt Fortran language and C language development in the investigation of some equipment manufacture industries.In design process, whole inputoutput datas of each calculation procedure adopt text and binary file.The design engineer requires a great deal of time and prepares the input data, and relies on experience fully and intuition is come the assay calculation result data.Design process and design data mainly all are that the design engineer can't manage a large amount of design datas by labor management.All design calculation process all is separate single process, can not realize the communication of striding course.Every design engineer manages independently and moves relevant engineering design system, and repeated workload is big, and Project design team can not realize the control of authority of concentrating and collaborative.
Shown in Fig. 1 (a), in the equipment design process, every slip-stick artist at first needs to set up input file, the input parameter in editor and the definite file; Move certain professional calculation procedure then, generate the output file that comprises result of calculation; At last, the slip-stick artist reads and analyzes output parameter, and determines whether recomputate or stop according to the satisfaction of result of calculation.When bearing multinomial Specialty Design task, every slip-stick artist also must change various inputs between a plurality of professional software for calculation.In this design, design engineer require a great deal of time reading, editor and revise design parameter in the input-output file.
In order to address the above problem, improve design efficiency and level, equipment preparation unit presses for and adopts system integration platform, the various professional software for calculation that needs in the integrated equipment preparation process.In the past, some equipment preparation units attempt to adopt product data management (PDM) system to come integrated multidisciplinary professional software for calculation and management design data.But commercially produced product data management PDM system all biases toward cad file and management of blueprint, and the data management granularity is bigger, can't be according to the granular management design data of parameter.And business-like PDM system only is fit to integrated business-like CAD software, is not suitable for the multi-specialized design software of integrated isomery.
In this case, people must develop the application integration platform at the multidisciplinary optimal design of complex equipment, Specialty Design software are registered and are disposed, the operation process of optimal control program, many design datas of unified management source, and support design engineer's collaborative design activity.Implement multidisciplinary design system ground in complex equipment development field integrated, at first must solve the unstructured data of isomery and the consistency problem between the structural data.The generation of (rather than on file hierarchy) management design data on concrete parameter level, obtain, change, storage and processing procedure, be the basis of setting up towards the collaborative integrated platform of the multidisciplinary optimal design of complex equipment.

Two, design document definition
Because there are the file that has nothing in common with each other in the multiplicity and the isomerism of multidisciplinary design software in the design process, design document defines the collection of promptly creating a file, and sets up the association between data file and the multidisciplinary design software.This document collection comprises the input and output file of design software, is stored in the file table of database.The base attribute information that the present invention needs when design document defines comprises reference number of a document, file name, file type, file specification and affiliated software identification.
1) reference number of a document is the unique identification of Parameter File in file set, encodes with " self-defined prefix+typing serial number " usually.
2) file type comprises three kinds of input file, output file and I/O files, and wherein the I/O file is meant that this document is an input file in running software, also is output file.The I/O file exists with two kinds of forms, and a kind of is that output data covers existing input data behind the running software; Another kind is that output data is appended in input file and write behind the running software, does not influence existing input data.
3) file specification is meant the remarks explanation to file, when between the different design softwares file of the same name being arranged, utilizes the clearly otherness between the description document of file specification.
4) software identification is to specify software under it for current file under.Can inquire all associated input and output files of registration software based on this software identification.
The process of design document definition may further comprise the steps as shown in Figure 4 in the inventive method:
Step 2. is selected design count software;
Whether step 3. typing fileinfo (fileinfo comprises reference number of a document, file name, file type, file specification and affiliated software identification), is to enter step 4, otherwise enter step 5;
Step 4. typing fileinfo is saved in this information in the database, promptly fileinfo is carried out database and adds operation, more the respective record of new database Chinese part table;
Three, design parameter definition
Have a large amount of variable parameters in each Parameter File, each variable all has its corresponding title, but the variable of same names may be represented different implications in different files.Therefore, when the user carries out the variable parameter definition, need to describe in detail the implication of parameter, can not produce the variable ambiguity.
The present invention is divided into two types with the concrete parameter in the Parameter File: variable and non-variable.Variable parameter is the parameter that needs dynamically change or load in the specific design process; Non-variable parameter is the character property parameter, is further divided into constant parameter and mark type parameter, and non-variable parameter must be bound mutually with concrete file, otherwise without any meaning.Since not related concrete file when parameter-definition, so parameter-definition is the variable parameter definition in the inventive method, but not the variable parameter definition will directly be positioned in the file according to concrete file.Design parameter definition is that parameter registration with Parameter File in the integrated system is in the argument table of database.The base attribute information that the present invention needs when design parameter defines comprises: parameter numbering, parameter name, parameter type, parameter format and parameter declaration.
1) the parameter numbering is the unique identification of variable parameter in parameter library, encodes with " self-defined prefix+typing serial number " usually.
2) parameter name refers to express the title of meaning of parameters, can also can be the expression formula of parameter for Chinese or English.
3) parameter type represents that is enumerated a collection, comprising numerous types of data, as character string, character, integer, lint-long integer, single precision, double precision and date.
4) parameter format refers to the concrete form of supplemental characteristic, for example: the parameter of " single precision " type, can define its form and be " f5.2 ", represent that this parameter accounts for 5 altogether, and keep 2 behind the radix point; The parameter of " date " type, form can be defined as YY-MM-DD.
5) parameter declaration is the detailed explanation to meaning of parameters, can be further specifying parameter name; Also can be that the otherness of parameter of the same name between the different Parameter Files is described.
The process of design parameter definition may further comprise the steps as shown in Figure 5 in the inventive method:
Whether step 2. typing parameter information (parameter information comprises parameter numbering, parameter name, parameter type, parameter format and parameter declaration), is to enter step 3, otherwise enter step 4;
Step 3. typing parameter information is saved in database with this information, promptly variable parameter information is carried out database and adds operation, the more respective record of argument table in the new database;
Step 4. finishes.
Four, the Parameter File template generates
Before the format module customization of carrying out Parameter File, guarantee that corresponding file and parameter all carried out detailed, correct definition.As indicated above, the parameter in the file is divided into variable parameter and non-variable parameter two big classes, and when the layout location of file, variable parameter is to select from existing variable parameter storehouse, and non-variable parameter will be set up according to concrete file, directly be positioned in the file.Variable and non-variable parameter are accurately located, and have promptly determined the format module of this document.
1) variable location
The variable location is the description that distribution is hereof carried out to variable.Because the diversity of each software in multidisciplinary, Parameter File changes various, and according to different design conditions, but the variable parameter show or hide also can carry out single cycle or Multiple Cycle, so the location of variable need accurately provide its positional information hereof.The base attribute information that the present invention needs when variable is located comprises: reference number of a document, form numbering, parameter numbering, preposition parameter, control script, row recurrent formula and row recurrent formula.
1. reference number of a document is represented the current file that will carry out the parameter location, and this numbering derives from the file set of having set up.
2. the form numbering is to be the numbering that the improve parameter unification in the file carries out when file template customizes, and this numbering is the unique identification of parameter current in this document.
3. parameter numbering is the numbering of parameter current in parameter library, and the parameter numbering can not the unique identification parameter current, because parameter current may repeatedly occur hereof, at this moment with regard to needs " form numbering " parameter current is carried out unique identification.
4. preposition parametric representation is located the last parameter of parameter current hereof, and preposition parameter can be a parameter, also can be an argument sequence.Preposition parametric representation parameter current hereof, from the position that the angle of order is determined.For first parameter of file, or first argument sequence (the first parameter of file can be an Argument List of exporting side by side), its preposition parameter is " null ".
5. control script by grammer limit parameter current is set demonstration whether and the condition and the number of circulation in groups (circulation is meant that a plurality of parameters circulate simultaneously in groups), the present invention is referred to as " systemic circulation " with the circulation in groups that multiparameter participates in.
6. the recurrent formula of going is used to control single-cycle number of parameter current.Need the substance circulation time for parameter hereof, will control by this formula.
7. the row recurrent formula is used to control the single cycle number of parameter current, or many circulations number.When the row recurrent formula was sky, the row recurrent formula was used to control the single cycle number of parameter current; When existing capable recurrent formula, when the row recurrent formula is arranged again, the expression parameter current will carry out dual circulation.
The process of variable parameter document alignment may further comprise the steps shown in Fig. 6 (a):
Step 2. is selected design document from file set;
Step 3. reads parameter from parameter library;
Whether step 4. detects is first parameter, is to enter step 5, otherwise enter step 6;
The preposition parameter that step 5. is provided with parameter is " null ", directly enters step 7;
Step 6. is provided with the preposition parameter of parameter as requested;
Step 7. judges whether parameter current needs to control script, is, enters step 8, otherwise enters step 9;
Step 9. judges whether parameter current needs the row circulation, is to enter step 10, otherwise enter step 11;
Step 11. judges whether parameter current needs the row circulation, is to enter step 12, otherwise enter step 13;
Step 12. is provided with cycle index according to the row recurrent formula;
Step 13. is selected interpolation, modification, deletion action;
Step 14. judges whether read parameter finishes, and is to enter step 15, otherwise enter step 3;
Step 15. finishes.
2) non-variable is located
Non-variable location is according to the actual conditions in the concrete file, and constant and mark distribution are hereof carried out accurate description.The base attribute of the non-variable parameter that the present invention extracts is: reference number of a document, form numbering, non-types of variables, constant value, marked content, preposition parameter and control script.
1. reference number of a document is represented the current file that will carry out the parameter location, and this numbering derives from the existing file set.
2. the form numbering is to be the numbering that the improve parameter unification in the file carries out when file template customizes, and this numbering is carried out unique identification to parameter current in this document.
3. non-types of variables is divided into constant and mark.
4. constant value represents for non-types of variables to be the parameter of constant, need provide constant value.
5. marked content is represented need provide the particular content of mark for the parameter of non-types of variables for mark.
5. preposition parametric representation determines the last parameter of parameter current in data stream, this preposition parameter can be one, also can be an argument sequence arranged side by side.Preposition parameter is mainly the expression parameter current hereof, from the position that the angle of order is determined.Obviously, for first parameter (also may be first argument sequence, because the first parameter of file can be an Argument List of exporting side by side) of file, its preposition parameter should be " null ".
6. control script and variable the location described in script identical.
The process of non-variable parameter document alignment may further comprise the steps shown in Fig. 6 (b):
Step 2. is selected design document from file set;
Preposition parameter when step 3. is selected non-variable location;
Step 4. is judged the type of non-variable parameter, if the constant type enters step 5, if the mark type enters step 6;
The variate-value of step 5. input default directly enters step 7;
Step 6. input marked content;
Step 7. judges whether parameter current needs to control script, is, enters step 8, otherwise enters step 9;
Step 9. is selected interpolation, modification, deletion action;
Step 11. finishes.
Five, Parameter File dynamically shines upon
After the Parameter File template generates, can carry out the executable operations of multidisciplinary software, before software is carried out, can carry out the extraction of certain history parameters file, also can import a new input file.When importing file, the inventive method is determined parameter value by document analysis, and the user can make amendment to the structured parameter after resolving, and will revise the result and react to input file, promptly changes from the structuring to the destructuring.After design software is finished, need be the visual structural data that provides of parameter in the output file from destructuring to structurized conversion.The process of entire parameter conversion will comprise file reduction and two reciprocal processes of document analysis by dynamically mapping realization.
1) file reduction
The file reduction is that the parameter list that will format output regenerates Parameter File.When writing existing parameter in the file again, need not carry out parameter format conversion, unifiedly carry out parameter according to string format and write, all parameters write finish after, real Parameter File forms.
2) document analysis
Document analysis is to be structurized, concrete parameter with non-structured document analysis, and the present invention adopts the method for " preposition parameter guiding, script cycle control " to carry out the dynamic parsing of file.According to the explanation in " generation of Parameter File template ", each variable parameter has attributes such as reference number of a document, form numbering, parameter numbering, preposition parameter, control script, row recurrent formula and row recurrent formula when the template layout; Each non-variable parameter comprises reference number of a document, form numbering, non-types of variables, constant value, marked content, preposition parameter and control script essential information when the template layout, the resolving of whole file is served as theme with " preposition parameter ", resolves one by one.
The document analysis flow process may further comprise the steps as shown in Figure 7:
Step 2. reads the argument sequence (may be a parameter, also may be a string arranged side by side parameter) of preposition parameter for " null ";
Step 3. judges that the length of argument sequence whether greater than 0, is to enter step 4, otherwise enter step 24;

Step 24. finishes.
Six, the many version managements of Parameter File
Document analysis during multidisciplinary design software is integrated promptly exists based on concrete data for each Parameter File in actual applications at many versions, multioperation, and each effective variable parameter data all will be carried out version and be preserved after design.
At first will carry out input data file before the application software operation prepares, can by between carry out the importing of file, also can carry out the file reduction process, promptly from the parameter value table, take out one group of (representing a version) supplemental characteristic, carry out validity check, when the operator is satisfied, then directly be reduced to file, thereby prepare the operation application software; When the operator carries out local data modification, write again in the parameter value table with the sign of redaction, and be reduced to input file simultaneously.After carrying out design software, the operator need check the output file of generation, and promptly the document analysis process will be carried out the preparation of input parameter again, and then be carried out running software when the operator is very dissatisfied to result data; When the operator thinks that result data is better, the parameter value in the output file is saved in the parameter value table, carry out the design software operation once more, till result data makes the operator satisfied.Therefore in calculating and design process repeatedly, be easy to produce many group inputs, output data, the inventive method all is kept at these active datas in the database in structurized mode, and the handled easily person carries out checking and adding up of old version data.In database, need three tables of data for many version managements, be respectively parameter value table, input file table and output file table.
Many version managements of Parameter File flow process comprises following concrete steps as shown in Figure 8 in the inventive method:
Step 2. reads parameter from database;
Step 3. shows input parameter;
Step 4. judges whether input parameter is effective, is, enters step 6, otherwise enters step 5;
The reduction of step 6. input file promptly generates input file;
Step 7. is carried out design software;
Step 9. is determined the validity of output parameter, better, enters step 10, and is relatively poor, enters step 11, the satisfied step 12 that enters;
Step 11. deletion I/O file returns step 5;
Step 12. is preserved parameter (document retaining also is saved to database);
Step 13. finishes.

A preferred embodiment of the present invention such as Fig. 9～shown in Figure 17.In this example, adopting Microsoft Visual C++6.0 is the code compiling instrument, and data base management system (DBMS) has adopted SQL Server 2000, sets up database name and is called " MetaFile ".
The integrated platform of Fig. 9 for using in this example, integrated platform except that functions such as project management, control of authority and communication are provided, be to the integrated of various design software system with integrate.
The business object class of Figure 10 for setting up in this example.Because it is the code compiling instrument that this example adopts Microsoft Visual C++6.0, therefore set up object class, corresponding with the content of tables of data shown in Figure 3 in the summary of the invention.The business object class comprises file, variable, parameter value, input file, output file, variable location, non-variable location, application software, order parameter example in this example.
Figure 11 is a file definition interfaces in this example, the user is when defined file, system will carry out automatic numbering to file, number format is five codings in this example, and be bebinning character with " F ", be " F0004 " as 1D_Input reference number of a document among the figure, file type is the I/O file, file specification is the input file of one dimension scheme, and affiliated software is one dimension computation optimization software.After the complete information typing of carrying out the file base attribute, the user can carry out " interpolation " operation.System comes file object is operated by ADO database manipulation class, makes that the field value in the file table is corresponding one by one in attribute and the database of file object.When Parameter File need be revised or lose efficacy, the user carried out " modification " and " deletion " operation to file, and its method of operating is identical with " interpolation " operation.
Figure 12 is the definition interfaces of variable parameter in this example, the operator is when the defining variable parameter, system will carry out automatic numbering to variable parameter, the number format of variable is eight codings in this example, and be bebinning character with " P ", be numbered " P0000005 " as the total pressure variable amount of import among the figure, after the complete information typing of carrying out the variable base attribute, the operator carries out " interpolation " operation, system comes variable object is operated by ADO database manipulation class, makes that the field value in the argument table is corresponding one by one in attribute and the database of variable object.When variable parameter need be revised or lose efficacy, variable is carried out " modification " and " deletion " operation, its method of operating is identical with " interpolation " operation.
Figure 13 is a variable location surface chart in this example, and in this example form being numbered with " DPL " is initial character string, adopts 10 coded formats, and the variable parameter typing comprises control script, row recurrent formula and three attributes of row recurrent formula.As long as the operator provides position and the control information hereof of each concrete parameter, program will come variable object is operated by ADO database manipulation class, make that the field value in the argument table is corresponding one by one in variable anchored object attribute and the database.Equally, when the operator revised parameter locating information or the inefficacy of parameter locating information, the method for operating of locating information being carried out " modification " and " deletion " was identical with " interpolation " operation.
Among Figure 13 control script be " show:DPL0000002=' a '; Cyc:DPL0000001 ", show is used for controlled variable and shows; Cyc is writing a Chinese character in simplified form of cycle, expression controlled variable and the common round-robin number of times of other parameter, i.e. cycle index in groups.The demonstration of this control script represenation parameter current is controlled by " DPL0000002=' a ' ", if this condition is set up, then shows, shows otherwise do not carry out parameter.Simultaneously, the demonstration number of parameter current is by " DPL0000001 " conditional decision, if " DPL0000001=0 " then played the effect of hiding parameter current equally, because 0 time circulation is skimble-skamble; " if DPL0000001=2 " then parameter current will carry out 2 times circulation and show that the circulation of indication here is the circulation of carrying out jointly with other parameter, but not the circulation of parameter current self.
The row that follows of parameter self is controlled by row circulation and row recurrent formula.What retouch the limit with black surround in the part shown in Figure 14 (a) is two loop bodies arranged side by side, and loop body 1 and loop body 2 will be controlled by " cyc " script in this case.The row recurrent formula is used to control single-cycle number of parameter current, and file parameters needs the substance circulation time, will control by this formula.Be the single cycle part shown in Figure 14 (b), " 11 " are an expression computer installation number (jm) variablees in this part, parameter in the black surround is a loop body, the period of this parameter deducts 3 by front variable jm and controls, getting DPL0000013 now is the form numbering of jm variable, inserts " DPL0000013-3 " in the recurrent formula of at this moment just need being expert at.Figure 14 (c) is depicted as two cyclic parts, " 7 " of first row are an expression initial streamline number (kon) variablees in this part, be used to control the columns of back loop body, " 1 " with delegation is an expression streamline number (lm) variable, be used to control the line number of back loop body, parameter in the next line black surround is a loop body, and the capable period of this parameter is controlled by variable " lm*2 ", and the row period is controlled by variable kon.Getting DPL0000016 is the form numbering of kon variable, and DPL0000015 is the form numbering of lm variable, inserts " DPL0000015*2 " in the recurrent formula of at this moment just need being expert at, and inserts in the row recurrent formula " DPL0000016 ".
Figure 15 is a non-variable location surface chart in this example, and the form numbering is an initial character string with " RPL " in this example, adopts 10 coded formats equally, and entry information comprises the control script.When parameter type was constant, the constant value attribute was effective attribute; When parameter type was the mark type, the content of mark was effective attribute.As long as the operator provides position and the control information hereof of each concrete parameter, program will come variable object is operated by ADO database manipulation class, make that the field value in the non-argument table is corresponding one by one in attribute and the database of non-variable anchored object.Equally, when the operator revised parameter locating information or the inefficacy of parameter locating information, the method for operating of locating information being carried out " modification " and " deletion " was identical with " interpolation " operation.
Relate to the order parameter row in variable and the accurate positioning instant spanned file of the non-variable parameterized template, the level that order parameter is listed as according to parameter distribution carries out the non-random access parameter.The order parameter row comprise reference number of a document, sequence number, preposition parameter and four attributes of rearmounted parameter, shown in the tabulation of the order parameter in the database.Preposition parameter and rearmounted parameter all are meant the form numbering of parameter, and these two attributes carry out carrying out assignment after preposition parameter is selected the user.Sequence number in the order parameter row is then used when a plurality of parameters exist side by side, for example: the rearmounted parameter of form numbering " DPL0000002 " has " DPL0000003 ", " DPL0000004 ", " DPL0000005 ", " DPL0000006 ", " DPL0000007 ", " DPL0000008 ", " DPL0000009 ", " DPL0000010 ", " DPL0000011 " and " DPL0000012 " ten in the 1D_Input file, the expressed hereof meaning difference of these ten parameters, therefore in the process of file parameters mapping, distinguish by the sequence number attribute.
The Parameter File template is carried out Parameter File and is dynamically resolved after generating.Can directly import Parameter File during parsing, also can from database, extract, can carry out the mapping of file and parameter after file is selected.Relate to three business object classes in this example in the process of document analysis and reduction: parameter value, input file and output file.
Dynamically the input file of resolving can only be selected in file template, by data base querying file table, need to select the file of parsing, and imports the relevant parameter file.The file reduction rear interface displayed map that is shown in Figure 16.
Parameter File imports laggard style of writing part and resolves, and the attribute of parameter value class comprises reference number of a document, form numbering, parameter numbering, version number, parameter value and creation-time.Process of analysis preposition parameter from the file layout table is that the parameter of " null " begins, and forms parameter list after parsing is finished.The interface display figure that is behind the document analysis shown in Figure 17.
