The structure type of technique content tree and the display of level grid etc.；The definition of node property includes to " in the tree whether node
One system such as display ", " the corresponding tables of data of node ", " title of node ", " whether needing to add class node ", " reticulate layer "
The definition of column property.
The access of two class data involved in structured processes unit, one kind are the definition data of process structure, and one kind is knot
Structure chemical industry skill instance data.
1) the definition data of process structure
The design structure chemical industry skill template definition tables of data of structured processes template definition tables of data is for storing technique knot
The definition information of structure, the definition information of hierarchical relationship, node property and nodal community including the upper node of definition structure tree；It is fixed
Each node includes a series of node property and nodal community on adopted structure tree, can use a node property table GC_
DEF_TREE stores the node hierarchical relationship data and node property data of definition structure tree, in addition with a nodal community
Table A TTRIBUTE stores nodal community data；The definition data of each process die are stored in node property table GC_
In this two tables of data of DEF_TREE and nodal community Table A TTRIBUTE；Entire template library usually contains many different techniques
Template, each template need a unique template ID, and corresponding field is denoted as CGCID, and CGCID should be used as table GC_DEF_
One of the major key of TREE and ATTRIBUTE；Other than above-mentioned two tables, a kind of technological procedure list GC_DEF_LIST is also needed
To record the index of different process regulation template, major key CGCID.
Node property table GC_DEF_TREE storage is the hierarchical relationship and node property data of node, due to each
Node all oneself unique ID, therefore node property table needs a major key CNODID to store unique ID of tree node, simultaneously
A field CPRNTNODEID is also needed for storing the corresponding father node ID of the node, constitute set membership (CNODEID,
CPRNTNODEID)。
Nodal community Table A TTRIBUTE major key be (CGCID, CNODEID, CID), while define two external key CGCID,
CNODEID, wherein external key CGCID is corresponding with the major key CGCIID in technological procedure list GC_DEF_LIST, external key CNODEID
It is corresponding with the major key CNODEID in node property table GC_DEF_TREE.
By to technological procedure list GC_DEF_LIST, node property table GC_DEF_TREE and nodal community table

There are the aggregation association of a 1:N, node property table GC_DEF_TREE and nodal community tables by node property table GC_DEF_TREE
There is also the aggregation associations of a 1:N by ATTRIBUTE.
2) structured processes instance data
Structured processes instance data table is used to store the instance data of node.A series of node is defined in definer
The data of (object class), all instance objects of the corresponding object class of each node require a node data table to deposit
Storage；The title of node data table is defined in the node property of definer, and the field information of node data table then comes
From the defined attribute data in nodal community Table A TTRIBUTE；The field information of node data table is in addition to fixed in nodal community table
Outside the attribute item of justice, also also known as to combine plus for constituting associated index field (F_ID0, F_ID1 ...) between data
Major key；The instance data table of root node (also referred to as first order node) uses F_ID0 and F_ID1 as joint index field, the second level
Node instance tables of data uses F_ID0, F_ID1 and F_ID2 as joint index field, and so on n-th grade of node instance data
Joint index field is used as with (F_ID0, F_ID1, F_ID2 ... ..., F_IDN).
Difference node defined in structured processes definer, their hierarchical relationship is indicated by definition structure tree,
And be corresponding to it, the corresponding instance data table of node then by the index field F_ID of different levels come structure node tables of data it
Between this hierarchical relationship.
The structured processes definition template is put in storage process are as follows: is put in storage after the completion of structured processes definition template
Publication, by definition template data storage into background server database.And before storage, it needs to total chemical industry skill
Template reasonability and integrality are audited.
It just can be carried out the processing of the storage publication of next step after the approval, there may be following two feelings when storage is issued
Condition:
A kind of situation is background data base there is no structured processes template of the same name, then the processing being directly put in storage,
And create the tables of data of node；Another situation is that there are structured processes template of the same name in background data base, then prompt is
Creation new version is still modified on the basis of original structured processes template；If on the basis of original template into
Row modification is then handled using the rule of process structure increment type modification；If generating new edition version, the version number of process die
Naming rule according to V1 V2 be named.
The core function of the structured processes editing machine is building process structure tree.The building process of process structure tree
Are as follows: in design structure chemical industry skill definer, a definition structure tree is constructed, is taken out a technological procedure using definition structure tree
The form of the different object class node of elephant indicates, and the type and hierarchical relationship of definition node.And structured processes
The process structure tree constructed in editing machine may be considered the instance object of definition structure tree.
By taking part process for machining as an example, incidence relation such as Fig. 3 institute of corresponding definition structure tree and process structure tree
Show, four layers of parent-child structure of one " process for machining-process-work step-tooling " is defined in definition structure tree, by the example
For a process for machining structure tree, wherein process for machining node instance turns to process for machining instance objects, procedure-node
The processes instant nodes such as " process 10 ", " process 20 " are instantiated as, in order to be more clear the layer of structure of process structure tree,
An Activity Classification node is added on tree, and using process instant node as its child node.Work step node instance turns to " work step
" 10-1 ", the work steps instant node such as " work step 20-1 ", since there are respective work step sections for each process instant node
Point, therefore work step instant node is inserted into the corresponding work step class node of respective process instant node.Process structure tree will
A technological procedure is organized by the Object node instantiated, can easily see the system knot of entire technological procedure clearly
Structure, it is succinct intuitive, and go deep into node level, the granularity of process management is more and more thinner.
When establishing node data table, in order to express in definition structure tree between the corresponding node data table of difference node
Hierarchical relationship constructs joint master of the one group of association index field (F_ID0, F_ID1 ... F_IDn) as node data table
Key.And the data source of the upper instant node of process structure tree is just being derived from node data table, each on process structure tree
Class node corresponds to a node data table, and each instant node then corresponds to one in corresponding node data table
Record.
The creation of process structure tree needs to be traversed for definition structure tree and goes up the corresponding node data table of all nodes to complete, and is
Improve the creation efficiency of process structure tree, the node for all levels that the not disposable creation of the present invention is set, each
When expanding node, grandson's grade data of the child node of present node, in this way when all nodes are unfolded, whole process structure tree are loaded
All buildings are completed.This mode for gradually loading node data, can be improved the operational efficiency of system, in node data amount
It is particularly important when very huge.The key algorithm of process structure tree creation is grandson's grade data of intron grade node.Its algorithm stream
Journey figure is as shown in Figure 4.
The algorithm of grandson's grade data of intron grade node is as follows:
A) present node is positioned, present node handle is obtained；
B) the next child node for positioning present node, obtains child node handle；
C) child node if it exists, i.e. node handle be not it is empty, then position tables of data corresponding to the child node, and obtaining should
The corresponding F_ID screening conditions character string of child node.The corresponding tables of data each record of the child node is traversed, if current record
The F_ID character string of synthesis meets F_ID screening conditions, then instant node corresponding to current record is inserted under child node, and
The title that the instant node is modified according to the node name of nodename ruled synthesis defined in node property, until having traversed
Step b) is repeated after the node data table；
D) child node if it does not exist, i.e. node handle are sky, then returning terminates.
The building process of level grid are as follows: the process structure tree that front is established constructs the technique frame an of structuring,
Entire process structure organizational form can be intuitively seen very much by structure tree, but is expressed only by process structure tree complete
The technique content in portion can make the structure of tree seem very too fat to move.For this purpose, the present invention proposes to use level grid auxiliary process structure tree
Carry out the detailed content of expression structure chemical industry skill.
(1) mapping relations between level grid, process structure tree and node data table
Level grid is a kind of special grid, and different from the display format of common grid, it is collection together in multiple related
The grid of connection relationship shows the Net Lattice Controls of grid data with tree form.Set membership between grid constitutes tree, brother
Younger brother's node data formed a grid, it is believed that be tree and grid it is compound.The corresponding number of each grid in level grid
According to table, fraternal sub-grid can share table, and every grade of grid at least corresponding tables of data, according to set membership, root grid is only
There is one, series one, also known as " level-one grid ", other grids are descendants's grid, and grid series sequence increases down.
Process for machining, process and the corresponding content of work step instant node are actually expressed as the three-level net of level grid
Lattice, there is one-to-one relationships for it and the upper class node of process structure tree, and wherein level-one grid (i.e. technique grid) is corresponding
The process for machining node of process structure tree, second level grid (i.e. process grid) correspond to procedure-node, three-level grid (i.e. work
Step grid) correspond to work step node.Under the class node of each physical record then corresponding thereto in different levels grid
Instant node there is the relationship that maps one by one, such as first under first physical record and procedure-node in process grid
Instant node " process 10 " is corresponding.
By being analyzed above it is found that there is mutually map between the present invention level grid to be constructed and process structure tree
Relationship, data between the two should keep real-time interactive, i.e., should be real on process structure tree when content is modified in level grid
Shi Xiugai, the variation on same process structure tree will also be reflected in real time in level grid.The data of the two all derive from
Node data table in background data base, therefore process structure tree, level grid, exist between node data table three and reflect each other
The relationship penetrated the, wherein corresponding (technology network of the first order grid of the first-level nodes (i.e. process for machining node) set, level grid
Lattice) and database in process node tables of data between correspond to each other；The process net in procedure-node, level grid on tree
It is corresponded to each other between lattice, procedure-node tables of data；The work step grid in work step node, level grid, work step number of nodes on tree
It is corresponded to each other according between table.
This corresponding relationship for being exactly based on the two carries out the association and interaction of tree with grid, to carry out the table of structured processes
It reaches.Using level grid, is conducive to the browsing and operation of data between association table, is shown with tree form, so that between grid
Data relationship is more clear clear.
(2) building of level grid
Front analyzes the specified node data table of data source that level grid is shown in database.In order to keep
The pending data of institute of the consistency of data, level grid are fully loaded in platform table cache before initialization.Level
Processing of the grid to data, directly interacts between table cache, has not only been able to maintain the consistency of data in this way, but also can improve data
Interactive efficiency.Therefore before creating level grid interface, data table cache is constructed first.Node in table cache and database
Tables of data is one-to-one relationship.In order to realize that the level of data is shown, there are certain incidence relation between each table cache,
After creating table cache, the incidence relation between caching, and the ID and other levels of caching field attribute, level grid are defined
The attribute that grid needs to configure.
1) tables of data is created
The corresponding tables of data of each grid is corresponding node data table in level grid.Number of nodes is being established in front
When according to table, hierarchical relationship between expression node tables of data constructs one group of association index field F_ID0, F_ID1 ... ...,
Joint major key of the F_IDN as node data table.The creation of tables of data is completed in program initialization.
2) data table cache is created
Node data table cache calling platform creates the interface function of table cache to construct, which compiles in structured processes
It is completed when collecting device initialization.Caching is separated with tables of data after creation, and all data in program operation process all pass through caching
It interacts, it just will in the corresponding data table of data cached restoring when to the last saving.When program exits, data are coped with
Table cache is discharged, to save system memory resource.
3) building of level incidence relation
The incidence relation of grid is consistent with the incidence relation of corresponding node data table in level grid, is all to pass through index
Field F_ID is constructed the character string of an incidence relation by the format of agreement, and using the character string as ginseng come what is be associated
Number is transmitted to setting grid hierarchical relationship platform interface function, to complete the building of grid incidence relation.
4) grid Column Properties are arranged
Parameters, these parameters such as column name, col width, editor's box type, background colour, which are mainly arranged, in mesh column attribute definition comes
The nodal community defined in the structured processes definer, the character string that these parameters synthesize in the way of agreement is transmitted to and is set
The platform interface function of grid Column Properties is set, to complete the setting of grid Column Properties.
5) level grid ID is set
The value of F_ID0 field is consistent in the node data table of same technological procedure, its node of different technological procedures
The F_ID0 field value of tables of data is different, therefore can make the value of F_ID0 using the value of F_ID0 as the ID of level Net Lattice Controls
The setting that platform interface function Set ID carries out level grid ID is transmitted to for parameter.
6) it creates level grid and shows
Complete node data table, the creation of table cache and the setting of grid hierarchical relationship, Column Properties, level grid ID
Later, calling platform interface function ReCreate Grid completes the creation of level grid.
It is the dynamic process constantly modified in Process Planning due to the complexity of technological design, therefore can produces
Raw different version, it is necessary to which the version of the technological design of different times is effectively managed.Objectification, the knot of technical factor
Structure, this itself favorably carry out version management to it.Technical factor is carried out group with the form of technique structure tree by structured processes
It knits and expresses, structured processes version management function can be realized by the version management to the upper instant node of process structure tree
Energy.
Whether issued according to version, the release status of instant node can be divided into compiled version and release.Compiled version is
The version that can be modified carries out submission audit after the completion of compiled version modification, forms release after the approval.Generally, one
Often there is many compiled versions and release in a instant node, in all compiled versions, there are a current compiled versions；Institute
Have in release, only exists a current release.If system is with the entrance of editor's identity, default load is to work as pre-editing
The data of version；If system is entered with the identity of viewer, default load is the data of current release.
Process structure tree be made of many instant nodes with hierarchical relationship, and each instant node there may be
Different versions, therefore a complicated incidence relation is constituted between the different editions of the instant node of different levels.
For this complicated incidence relation between version, structured processes using version management mode as shown in Figure 2 into
The management of row version.As seen from the figure, the version of father node, there is set memberships between corresponding child node version, such as
The version 10-V1 of " process 10 ", there are father and son passes with (the 10-V1)-A-VI and (10-V1)-A-V2 of " work step A " the two versions
System, with (the 10-V1)-B-VI of " work step B " and the two versions of (10-V1)-B-V2 there are set membership, the similarly version of process 10
There is also this similar set memberships with the version of its child node by this 10-V2.
In order to completely express the version information of instant node, version number (Version), version should be added in node data table
This state (VersionState), whether be current compiled version (CurEditVersion), whether be current release
(CurPublishVersion) the version properties field such as.The version pipe of instant node is controlled by these version property fields
The logic of reason.The processing logic of the version management of structured processes mainly includes the following aspects:
1) duplication creation new version
The release of instant node cannot directly modify, and if desired modify to the content of release, need
One new version of creation is replicated on the basis of the version.When carrying out duplication creation new version, not only instant example node
The version needs to replicate portion, and the corresponding all descendants's instant nodes of the version should all replicate portion, and version number is original
On the basis of be incremented by.As shown in Fig. 2, by the version 10-V1 of node " process 10 " carry out duplication creation new edition present treatment, then with
Version (10-V1)-A-VI of the child node of 10-V1, (10-V1)-A-V2, (10-V1)-B-VI, (10-V1)-B-V2 should be into
Row duplication creation new version.
2) new version is created
When instant node carries out creation new version, an empty record is created, version number is on the basis of original version number
It is upper to increase certainly.Its effect is similar with duplication creation new version, apparent both for modifying to announced version, but also
Difference, creation new version do not need the new version of creation child node, and replicate its child node when creating new edition version and replicate wound yet
Build new version.
3) version is issued
After the completion of the technological design task of a certain edit version of instant node, needs to change version and carries out submission audit,
The publication work of version is completed after the approval, and issued cannot study of version one changes.
4) old version is browsed
A certain instant node multiple versions if it exists, it is sometimes desirable to check some version, browsing old version is exactly complete
At this task.Instant node should load the corresponding version of the child node of the old version when carrying out checking a certain old version
This content.
5) version is deleted
Instant node not only deletes the content of the version when deleting a certain version, also deletes all descendants's sections of the version
The corresponding release content of point.
