Embodiments of the present invention will be described below with reference to FIGS.

FIG. 1 is a diagram showing an overall configuration of a design change management support system according to the present invention. This system edits the basic specification item database 101 for storing the basic specification items set in the existing design or the basic specification items created based on the specification items, the specification items of the created basic specification items, and the specification values. Basic specification item data editing device 102, design document created by one or a plurality of applications, and design document information extraction device 103 that extracts operation information and attribute information about the design document from screen information at the time of design document creation, extraction Design information database 104 that stores the operation information and attribute information that has been processed, and the relevance determination database 105 that stores data for determining the relevance between the specification items of the design document and the design drawings based on the past design document , Extraction of the changed part accompanying the specification change from the design document information and the relevance determination data and the relevance between the changed parts, Specification change / relevance information extraction device 106 for discriminating update procedures, specification change / relevance extraction information database 107 for storing the discriminated results, confirmation of extraction information of changed parts, relationship with basic specification items and changes Specification / comment registration device 108 for registering and editing information, change information list database 109 for storing the registration and edit results, and creating a list of changes and a history table for presenting the edited results extracted and edited The change point list / history table creating apparatus 110 and the change point list / history table database 111 for storing the change point list and the history table are configured.

Here, the attribute information related to the design document is information for specifying the design document and the design drawing, such as the extraction time of the changed portion, the name of the figure, the figure number, the page, and the image information.

In addition, it is assumed that the design drawing or the like is changed in accordance with the specification change of the design document, and the relevance information at this time is referred to as derived information.

FIG. 2 is a flowchart showing an example of a processing procedure when creating basic specification item data for determining the outline of the design in the design change management support system of the present invention shown in FIG.

For customization of standard products and product development similar to existing products, a part of the specification is changed based on the specification of the existing design document, and the related part of the existing design drawing is changed due to the change of this specification. In some cases, this processing procedure shows such a case.

After the start, the basic specification items set in the existing design are read as a template (step 201: hereinafter referred to as S201). Next, the basic specification item is edited such as addition or deletion to create a new basic specification item (S202). Further, a new specification value is registered by changing the specification value in the existing design or setting the specification value of the added specification item (S203).

Similarly, when a design document is revised by upgrading the version of the design document after the design is started (revision up), the basic specification items and specification values determined for the previous version (revision) are read, and the basic specification items can be edited. Register new specification values and exit.

FIG. 3 shows a design document information database 104, a specification change / relevance extraction information database 107, and a change information list database (when a design document is changed by the design document information extraction apparatus 103 shown in FIG. 109) An example of a user processing procedure for acquisition is shown in a flowchart.

After starting, when one or a plurality of applications are used to change one or a plurality of related design drawings according to an arbitrary specification change, a relevancy start process (S301) is performed at the start of a related change processing set. At the end of the related change processing set, the relevance end process (S307) is performed. This process is realized, for example, by the user performing an action for informing the system of the start or end of the related change process, and the related change points are set to the same group number. The determination other than the user action will be described later.

Next, for relevant changes, capture the screen of the design drawing at the start and end of the change for each page, and extract the screen information, operation information, and attribute information of the change due to the design change from the design document information (S302, S303, S304). Further, at the end of the design change of each page, a comment about the changed part is registered and the extracted information is edited (S305). The registration of a comment or the like includes a change point extraction registration process (S305) that is processed at the time of change point extraction and a change point registration process (S309) that is processed collectively after all the design document change processes.

Even if there is no specification change, the design drawing may be changed, and in this case as well, the related change processing can be processed in the same way.

FIG. 4 shows an example of the design drawing change example when the specification of the design document is changed, without using the design change management support system of the present invention.

An example 400 showing a part of the basic specification item data 101 shown in FIG. 1 in a simplified manner is shown. This is “a” when the value of specification item A is Rev. 0 (revision) 0, unchanged when it is Rev. 1 (“a”), “b” when the value of specification item B is Rev. 0, “B '” for Rev. 1), “c” when the value of the specification item C is Rev. 0, and “c ′” for Rev. 1). Furthermore, by changing the value of specification item B, P1 (Fig. V1) of part 410 of Rev.0 design document is changed to P1 (Fig. V1 ') 421 in part 420 of Rev.1 design document. However, P11 (FIG. L1 ′) 422 is further changed by the change. This is a series of change processes accompanying the change of the specification item B. Also, by changing the value of specification item C, P2 (Fig. V2) of part 410 of Rev.0 design document is changed to P2 (Fig. V2 ') 423 in part 420 of Rev.1 design document. However, P12 (FIG. L2 ′) 424 is further changed by the change. This is a series of change processes accompanying the change of the specification item C.

In this change process, there is no information about the set of related changes and the change procedure, so the information that can be understood from the design drawing after the change can be found in the Rev.0 design drawing, but the change process Derived information representing relevance or procedure is not saved (440).

FIG. 5 shows an example realized by using the design change management support system of the present invention in the example of changing the design drawing when the specification of the design document is changed.

Similar to FIG. 4, an example 400 is shown in which a part of the basic specification item data 101 shown in FIG. In the design change management support system of the present invention, the design document information extraction device 103 and the specification change / relevance information extraction device 106 shown in FIG. 1 can recognize the start of the related change processing and the end of the related processing, The process that P1 (Fig. V1 ') 421 of the design document 510 changes in Rev.1 with the change of the value of the specification item B, and the process that P11 (Fig. L1') 422 further changes due to the change This is recognized as a series of change processing 530 accompanying the change of the specification item B, and P2 (FIG. V2 ′) 423 of the design document part 540 is changed in Rev. 1 as the value of the specification item C is changed. And the process changed by P12 (FIG. L2 ′) 424 due to the change is recognized as a series of change processes 560 accompanying the change of the specification item C, and represents the order relationship of the change processes. The change procedure is saved.

FIG. 6 shows basic specification items which are input / output screens of the basic specification item data editing apparatus 102 for editing the specification items and specification values of the basic specification item data 101 shown in FIG. 1 in the design change management support system of the present invention. An example registration screen 600 is shown.

In this example, the basic specification item is composed of two layers of specification item 1 (603) and specification item 2 (604). The number of specification items can be added. The value set in the previous revision or the initial value of the template is entered in Rev. 0 (605) of each item. When changing the specification value by changing the specification in Rev.1, enter the changed specification value instead of the arrow ("←") indicating that it is the same value as Rev.0, and the changed location is a different color 606 is highlighted using a font. In this example, the specification value of the specification item “capacity” is changed to 525 kVA. Further, whether or not the specification value of an arbitrary specification item is changed or not, when the related design drawing is set, the state (S) is indicated by an arbitrary mark 620. In this example, the specification item indicates that a design drawing related to capacity, rated frequency, and rated current is defined.

7, in the design change management support system of the present invention, the design document information extraction device 103 illustrated in FIG. 1 extracts the design document information database 104 such as operation information and attribute information of the changed portion from the screen information of the design document. 700 showing an example of the screen at the time.

In this example, an action button 710 for executing the start and end processing of association with the screen 701 of the application for design change on the screen and the start and end of image capture of the design screen, the basic specification items shown in FIG. A registration screen 600 and a screen 800 for confirming the design document information 104 acquired by the design document information extracting apparatus 103 shown in FIG. 1 are displayed.

When a design document is created by an arbitrary application, the design document is created for each page. Therefore, the design drawing of each page of the application is displayed in a preset location and size, and before the design drawing is changed. By capturing an image of the design document after the change, the presence / absence of the change portion 704 and the position information of the change portion in the screen are extracted using the scale 702 of the design document and the position information of the image data. In addition, from the fixed information 703 described on each page of the design document, the figure name, figure number, figure type, Rev. number, page, sheet number, image capture time, application name, file name, and related information The group numbers extracted by the association start process at the start and the association end process at the end of the set of change processes to be extracted are extracted.

As for the timing of application change and page change, there is a method of extracting operation information from the application side in addition to extraction from an image. In addition to the user instructing the timing of image capture with an action button or the like, the image of one or a plurality of applications determined in advance at regular intervals is captured, and only the image in which a difference from the previous image is generated is stored. There is also a method.

FIG. 8 shows the display of the design document information (104) of the changed part extracted from the screen information of the design document as shown in the example of FIG. 7 and the history information about each changed part in the design change management support system of the present invention. An example of a screen for inputting a comment is shown (800).

In this example, the Rev. number 801, time 802, application file name 803, page 804, change location 805, figure type 806, relevance group number 807, and changed image data are stored for each change location. In this case, the data name 811 is displayed. In addition, in this example, when inputting a comment 808 for describing each changed portion in the history, selecting a relevant specification item 810, and adding detailed information in addition to the history comment for the changed portion, a detailed input button is used in this example. Another dialog 820 is opened from 809, and text input or a file link is made in the change reason other field.

In FIG. 9, in the design change management support system of the present invention, when the specification of the basic specification item is changed, a plurality of related design documents using a plurality of applications (part drawing creation application, connection diagram creation application) are displayed. An example of a processing procedure on the screen to be created is shown.

In this example, when the specification A of the basic specification item 600 is changed 901, and accordingly, using the parts drawing creation application, P3 / 60 (910) A (2) (911) and drawing number of the drawing number 111AB22334 111AB22334 P5 / 60 (920) A (3) (921) was changed, and using connection diagram creation application, P3 / 30 (930) A (4) (931) was changed to 111CD22445 Represents that. Next, when the specification B of the basic specification item 600 is changed 902, B (6) 1 (941) and B () of P31 / 60 (940) of the drawing number 111AB22334 using the part drawing creation application accordingly. 6) Change 2 (941), change B (7) (951) on page 21/30 (950) of diagram number 111CD22445 using the connection diagram creation application, and use other parts diagram creation applications Then, B (8) (943) of P31 / 60 (940) of diagram No. 111AB22334 was changed, and B (9) (952) of P21 / 30 (950) of diagram No. 111CD22445 using the connection diagram creation application ) Is changed.

FIG. 10 shows an example of determining the relationship and order of the changed parts extracted by the processing procedure shown in the example of FIG. 9 in the design change management support system of the present invention.

First, the result (1020) in the case where the information of the changed part is extracted for each page has no order relationship, and B (6) 1, B (6) 2 and B (8), B (7) and B ( 9) cannot be discriminated although the relevance is different. The result 1030 of determining the order relationship with the page change as a break for each page is A (2) → A (3) → A (4) → B (6) 1 and B (6) 2 → B (7 ) → B (8) → B (9) The order relationship can be set for each page. The result 1040 in the case of extracting information on the type of drawing or the application (in this example, the component diagram and the connection diagram, or the component diagram creation application and the connection diagram creation application in this example) can classify the changed portion.

Therefore, the change part is extracted for each page, and when the page is changed, it is set as an order relation separator, and the drawing type is also a relation separator. In this example, “part diagram → connection diagram” is the relation separator. And As a result, the order relationship is A (2) → A (3) → A (4) 1051, B (6) 1 and B (6) 2 → B (7) (1052), B (8) → B (9 3) related groups of 1053 can be discriminated. By setting the relationship between each group and the specification item, in this example, the specification item A and Group1 (1054), the specification item B and Group2 (1055), the specification item B and Group3 (1056), You can set the relevance of related changes.

FIG. 11 shows a change point list as an example of an output screen of the change point list / history table creation device 110 of FIG. 1 in the design change management support system of the present invention.

The change point list 1100 is a list for knowing derived information such as which drawing is changed by changing each specification item when the design change is completed, and which other drawing is changed by that. In this example, in the change point list, the relationship between the specification item 1110, the change specification 1120, and the drawings changed in accordance with the specification change, for example, the component diagram 1130 and the connection diagram 1140, and the order relationship (change procedure) of the change can be understood. It is displayed. In this example, the corresponding part of the design document after the actual part diagram or connection diagram is changed is displayed from the drawing information.

FIG. 12 shows a history table which is an example of an output screen of the change list / history table creation device 110 of FIG. 1 in the design change management support system of the present invention.

The log table 1200 is a table for referring to each page in time series about where the design document is changed when the design change is completed. By extracting design document information, specification change / relevance information, each changed part of the history table is automatically extracted and displayed together with input data such as comments. In this example, a Rev. number 1210, a page 1220, a sheet number 1230, a position 1240, a comment 1250, and a button 1260 for displaying a detailed comment for each changed portion are displayed.
