Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial application field) This invention is a task of checking and confirming the contents after creating a drawing (so-called CAD drawing) using a CAD (computer utilization design) system. The present invention relates to a CAD drawing check support system to be supported.

(Conventional technology) Conventionally, a CAD drawing is produced by a designer using a CAD system, output once in the form of a drawing, and then inspected and checked by a checker from two aspects of format expression and functional expression (ie, Checking) and signing. Here, the format expression check (graphical check) refers to the size of characters, the presence or absence of overlap,
It is to check whether the expression in the drawing such as the expression of the dimension line is sufficient. In addition, a functional expression check (functional check) is a function that is intended by a senior designer equal to or higher than the designer in the technical domain based on past accumulated technologies and the latest technology, and expressed in the target drawing. This is an operation for confirming whether the circuit can be performed as described above (for example, whether the circuit can operate as intended in an electric circuit diagram). The above check work was originally performed based on the experience of the designer and the know-how of the design department, and there was almost no tool to support it.

Nowadays, the support area of CAD has expanded,
As for the checking of overlapping, prohibited notation, etc., data is automatically checked by the inputting man-machine. In addition, functions such as changing the original drawing and displaying the changed part in a different color have been added, and most of the notation checking (schematic checking) has been realized in the system. However, there is no support tool for the function check because of its nature reflecting the designer's design intention.

(Problems to be Solved by the Invention) As described above, there are two types of inspection work for CAD drawings: a schematic inspection and a functional inspection. Of these, the functional inspection is performed based on the experience of the designer and the know-how of the design department.Because it depends on the contents of the drawings, there are a wide variety of check elements. There was no.

In this way, with the conventional functional inspection method that was performed based on the experience of the designer and the know-how of the design department, the large number of drawings that were copied and written by the CAD system were once accurate notation, so careless In addition, there is a problem in that, when a different type of drawing appears between similar drawings, or when a different type of drawing appears between similar drawings, it is easy to cause skipping due to confusion in the inspection procedure.

The present invention has been made in view of the above circumstances, and its purpose is to be able to automatically display, on a part of the same screen, a check check list optimal for checking a CAD drawing displayed on the screen, An object of the present invention is to provide a CAD drawing inspection support system capable of performing inspection efficiently without omission.

Another object of the present invention is to provide an identification mark (such as a checker's name, a signature image or a seal image) indicating that the check has passed only when there is no check item that has been judged as “No”. An object of the present invention is to provide a CAD drawing check support system that can fill in a target CAD drawing and thereby perform highly reliable checking.

Still another object of the present invention is to allow only a valid checker of a CAD drawing to be checked to perform the checking work on the CAD drawing, thereby enabling more reliable checking. An object of the present invention is to provide a CAD drawing check support system.

[Structure of the Invention] (Means for Solving the Problems) The present invention has a wide variety of check check elements when looking at various CAD drawings as a whole, but when focusing only on a certain design department or individual design field, A drawing type code that indicates the type of the same drawing in the CAD drawing drawing attribute information. And a checklist library in which checklists for checking various CAD drawings are registered for each drawing type, and a drawing type in the drawing attribute information added to the CAD drawing to be checked. A check checklist selection means for extracting a check checklist specific to the drawing type indicated by the code from the check checklist library, and checking the extracted check checklist. Checklist display / input means for displaying in a partial area on the screen where the elephant CAD drawing is displayed, and accepting the input of check results for each check item in the check checklist on this screen, and this checklist Only when the input acceptance of the display / input means is completed and no “No” judgment result is input to any check item of the check check list on the screen, an identification mark that can confirm that fact is displayed. A check output means for setting a drawing to be checked is provided.

In addition, the present invention comprises a drawing type code composed of a plurality of keywords, for example, while preparing a sub-checking checklist for each keyword in the checking checklist library instead of a checking checklist for each drawing type, It is also possible to take out a sub-check checklist unique to each keyword constituting the drawing type of the CAD drawing to be checked, combine it into one check checklist, and use the checklist.

If a "No" determination result is entered for at least one check item in the checklist on the screen, the check item (and the problematic part on the drawing that caused the "No" determination) It is also possible to further provide an indication list output means for outputting an indication list including (information indicating).

The present invention further sets a designer code indicating a designer of the CAD drawing to which the same information is added in the drawing attribute information, and allows a checker code indicated by the code to be checked by the checker code. A checker registration library in which checker registration information including a designer code of a designer and a drawing type code indicating a drawing type that can be checked by the checker is registered for each checker is provided. Based on the designer code and drawing type code in the drawing attribute information added to the target CAD drawing and the checker registration information in the checker registration library unique to the checker who is going to check It is determined whether or not this checker is a valid checker of a CAD drawing to be checked, and only when the checker is a valid checker, the checker is permitted to perform the check work. It is characterized by the following.

(Operation) Next, the operation of the CAD drawing check support system of the present invention will be described. First, when a check operation for a certain CAD drawing is specified to the system, the CAD drawing (check target C
A drawing type code (this code is, for example, set at the time of drawing creation) in the drawing attribute information added to the AD drawing) is extracted, and a drawing check code specific to the drawing type indicated by the drawing type code is extracted. The checklist is retrieved from the checklist library by the checklist selection means. This extracted checklist is
The checklist display / input means is displayed in a partial area (window) on the screen on which the CAD drawing to be inspected is displayed. The checker performs a check work on the CAD drawing to be checked on the screen according to each check item in the check check list in this window, and uses a mouse or a keyboard or the like to check the check result (“good”). "Or" No "determination result) in the corresponding check item (result entry column). With this operation, the check result of the checker is written in the check item of the check list on the screen. Only when the check results are entered in all the check items and there is no check item with "No" judgment result,
An identification mark (such as the name of a checker, a signature image, a seal image, or the like) that can confirm the change is automatically set by, for example, a check output unit in a checker column (signature column) of the CAD drawing to be checked.

In this way, the checklist specific to the drawing type of the CAD drawing to be checked is automatically selected and displayed in the window, so the checker must perform the check work according to the checklist on the screen. As a result, reliable inspection without omission of check can be performed. In addition, all check items are checked without omission, and the signature of the checker can be input only when there is no check item in which the "No" determination result is entered. The performance is improved. In addition, at least one "No" in the checklist
If there is a check item for which a determination has been made, the check item and information on the problematic point (pointed-out point) in the CAD drawing to be checked (the pointed-out point) on which the determination was made The index list having the coordinate values or the symbol names generated based on the coordinate values) is automatically output by the index list output unit, thereby reducing the burden on the figurer. It becomes possible.

In addition, a designer code indicating the designer of the corresponding CAD drawing is added to the drawing attribute information, and in the configuration in which the checker registration library is provided, the CAD drawing on the display screen by the checker is added. At the time of the checker work, the designer (code) and drawing type that the checker can check from the checker registration information unique to the checker (registered in the checker registration library) (Code), and by checking whether there are any CAD drawing designers and drawing types which are indicated by the drawing attribute information, check that the drawing checker It is possible to determine whether or not the user is a valid checker of the CAD drawing. Only when the legitimate checker is determined, the check target CA on the screen is displayed.
By permitting inspection work on D drawings, more reliable inspection is possible.

FIG. 1 is a block diagram of a CAD drawing check support system according to an embodiment of the present invention. In the figure, 10 is
Checking support equipment to support CAD drawing check work, 30
Is a drawing database in which various CAD drawings (CAD drawing data) are registered. Each CAD drawing registered in the drawing database 30 is added with drawing attribute information indicating the attribute of the drawing. The drawing attribute information is generated by a drawing attribute setting means (not shown) when the corresponding drawing is created, and as shown in FIG. 2, a drawing number unique to the drawing and a drawing indicating the type of the drawing The information includes a type code, a creation date of the drawing, a designer code indicating a designer of the drawing, and a checker code indicating a checker of the drawing. Note that the checker code in the drawing attribute information has a null value when the drawing is created.

Referring again to FIG. 1, reference numeral 40 denotes a database (hereinafter, referred to as a check database) in which information for check check support is registered in advance. The checker database 40 includes a checker registration library 41 in which checker registration information indicating the range of qualifications of the checker and the checker is registered for each checker and a checker check list. It consists of a checklist checklist library 42 registered for each type. Checker registration library
As shown in FIG. 3, each of the checker registration information in 41 includes a checker code, a signature image (a name, a seal image, etc.) of the checker indicated by the checker code,
The information includes a designer code indicating a designer who can check the drawing and a drawing type code indicating a drawing type that can check the drawing. As shown in FIG. 4, each check check list in the check check list library 42 includes a drawing type code indicating a corresponding drawing type and information on check items (check items).

The check drawing support device 10 checks whether or not the checker who is going to check the CAD drawing with the support of the device 10 is a valid checker in the checker registration library 41. Checker judging unit 11 that judges based on the user registration information, and a checker that outputs a warning message to that effect when the checker judging unit 11 determines that the user is not a valid one. Inappropriate qualification output section

And an input completion / result determination unit 18 for performing the determination.

In addition, as a result of the check, if there is no check item determined to be “No”, the check check support device 10 performs the check.
The checker check output unit 19 that sets and outputs the signer's signature image in the checker sign field of the CAD drawing, and the judgment is normal
A normal end processing unit 20 for outputting a CAD drawing or saving a file; and, if there is at least one check item (that is, a pointed item) determined to be “No” as a result of the check, the pointed list (that is, a pointed item list) Issue list output unit 21 for outputting a problem issue list) and saving an output list from the issue list output unit 21 or a warning message from the checker qualification improper output unit 12, or send these to the designer via a network. And an abnormal termination processing unit 22 for transferring. The indication list output from the indication list output unit 21 is in the format shown in FIG. 5, and includes, in addition to the drawing number, the check date, the checker code, the check item determined to be “No” and the drawing. Includes a pair of coordinate values at the point indicated above.

Next, the operation of the CAD drawing check support system having the configuration shown in FIG. 1 will be described.

First, the checker performs predetermined input operations necessary for ensuring security, such as designating a user ID and inputting a password, to the checker assisting apparatus 10, and after indicating that the checker is himself. Enter the procedure for the check work. Note that the above security processing is not directly related to the present invention and is well known, so that detailed description will be omitted.

Now, the inspector specifies the inspection target drawing created by the CAD system by the designer to the inspection support apparatus 10,
An instruction to start a check is given. As a result, the specified drawing target drawing (data of) is retrieved from the drawing database 30 to an internal memory (not shown), and the retrieved drawing target drawing is displayed on the entire screen of the display monitor. In this state, the checker judging section 11 in the checker assisting device 10 is activated.

The checker determining unit 11 searches the checker registration library 41 in the check database 40 using the checker code of the checker who instructed the check, and checks the checker unique to the checker. The registration information (see FIG. 3) is extracted. In addition, the checker determining unit 11 extracts a drawing type code and a designer code from the drawing attribute information (see FIG. 2) of the drawing to be checked extracted from the drawing database 30. Then, the checker determining unit 11 determines whether or not a designer code indicating a designer of the drawing to be checked is registered in the checker registration information extracted from the checker registration library 41, that is, performs the check. It is checked whether or not the figure checker who is described is a designer who can check the figure. In addition, the figure checker judgment unit 11
Is whether the drawing type code indicating the drawing type of the drawing to be checked is registered in the checker registration information extracted from the checker registration library 41, that is, It is checked whether the drawing type can be checked.

If the drawing to be checked is created by a designer who can check the drawing, and the drawing type is a drawing type that can be checked by the checker, the checker determination unit 11 determines that the checker is It is suitable for checking the drawing to be checked and is determined to be a legitimate checker, and activates the production division determining unit 13. In this way, the production division determination unit 13 checks whether the drawing to be checked is a corrected drawing (a newly created drawing), and if the drawing is a corrected drawing, activates the corrected part display unit 14. As a result, the correction portion display section 14 extracts the correction portion, and performs color change display or hatching display of the correction portion of the drawing to be inspected displayed on the screen.
In addition, there is a method of determining the corrected portion by adding change information to a part of the vector information which is the original information of the CAD, or by expanding all the information into an image, and then detecting a mismatched portion. Detailed description is omitted because there is no implicit relationship.

On the other hand, if the drawing to be checked is not created by a designer who can check the drawing, or is not a drawing type that can be checked by the checker, the checker determination unit
11 is not suitable for the checker of the drawing to be checked,
It is determined that the checker is not a valid checker, and the checker qualification improper output unit 12 is activated. This makes the checker qualification inappropriate output unit 12
Generates and outputs a warning message for notifying that a worker (checker) who is currently trying to check is ineligible. This warning message is notified to the designer by the abnormal termination processing unit 22 via, for example, a network.

In this embodiment, it is assumed that the checker determining unit 11 determines that the checker is qualified. In this case, the production division determination is performed by the production division determination unit 13 as described above, and if the drawing to be inspected is a correction drawing, the correction part display unit 14
, The drawing type discriminating unit 15 is started immediately if the drawing is not a corrected drawing.

The drawing type determining unit 15 determines the drawing type of the drawing to be checked from the drawing type code in the drawing attribute information of the drawing to be checked, and activates the check check list selecting unit 16. The check check list selection unit 16 extracts a check check list (see FIG. 4) of the drawing type determined by the drawing type determination unit 15 from the check check library 42 in the check database 40, and checks the check list. The display / consumption input unit 17 is activated. As a result, the checklist display / consumption input unit 17
First, it was extracted by the checklist checklist sorting unit 16,
A check checklist specific to the drawing type of the drawing to be checked is displayed in a window on the screen on which the drawing to be checked is displayed. FIG. 6 shows an example of the display screen at this time.

In the example of the display screen of FIG. 6, a circuit diagram 60 to be checked is displayed on the entire screen of the display monitor, and furthermore, the same drawing 60
This shows a state where a check check list 70 of 60 is displayed in a window. In this embodiment, the circuit diagram
Reference numeral 60 is a relay sequence circuit diagram. When an ON switch (switch ON contact) 62 is turned ON, a holding relay 63 is operated, a self holding is performed by a self holding contact 65, and a self holding is performed by a OFF switch (switch OFF contact) 64. And a circuit in which the relay 63 is brought into a non-operating state. Checking checklist 70
Is a window showing typical check items in such a circuit (relay sequence circuit).
72, a check item 73 for the surrounding circuit, and a check item 74 for preventing the surge of the relay. Note that the switch off auxiliary contact 61 is newly added for the off-priority circuit configuration, and the corrected portion (added portion) is clearly indicated by displaying the corresponding portion by hatching on the corrected portion display section 14. . Further, the surge suppressor (surge prevention circuit) 66 of the relay indicated by the broken line indicates a state in which what should have been originally entered is omitted due to a design error.

When the checker checklist (70) as shown in FIG. 6 is displayed on the window, the checker checks the checker checklist (70) for the drawing to be checked (circuit drawing 60) displayed on the screen. The function check indicated by each check item (71-74) is performed. Then, the checker operates a mouse, a keyboard, and the like, and as a result of the function check, “○” if the judgment is “good”, “x” if the judgment is “no”, and “−” if the judgment is not applicable. In the check result entry column (75-78) of the corresponding check item (71-74). This entry process is performed by the checklist display / consumption input unit 17 in response to an input from a mouse, a keyboard, or the like.

In the example of FIG. 6, first, the check item 71 of the disconnection circuit priority in the check check list 70 is checked, and the disconnection auxiliary contact 61 is added as described above. "Good" judgment result (（) is entered.
At this point, even if an attempt is made to enter the checker signature field 68 of the drawing sign 67, the following check items 72 to 74 have not been checked yet, and as long as the check result entry fields 76 to 78 are blank, You cannot perform a check sign. There is no corresponding check item 72 for holding when the power is turned off, and the check result entry column 76 is marked as not applicable (-). Further, as for the next check item 73 of the surrounding circuit, a “good” judgment result (○) is entered in the check result entry column 77. Regarding the check item 74 for preventing the surge of the last relay, since the surge killer 66 of the relay 63 has been omitted, the check result entry column 78 shows “No”.
The judgment result (x) is entered.

As described above, the check result entry fields (75 to 7) for each check item (71 to 74) in the check check list (70)
8) The check result (judgment result) is entered for each,
When the blank check result entry column no longer exists, the input completion / result determination unit 18 determines that the input of the check result to the check check list (70) is completed. When the input completion / result determination unit 18 determines that the input of the check result has been completed, the input completion / result determination unit 18 displays “+” in at least one of the check result entry columns (75 to 78) of the check items (71 to 74) in the check check list (70). It is checked whether or not a “No” judgment result (×) is entered.

If there is at least one check item in which a “No” determination result (×) is entered (the check item in the example of FIG. 6)
74), that is, if there is at least one indicated part in the drawing to be checked (here, the circuit drawing 60), the input completion / result determination unit 18 activates the indicated list output unit 21, and the indicated list output unit 21 Creates and outputs an indication list (pointing list information) in the format shown in FIG. 5 including a check item in which a “No” determination result (×) is entered. Here, since the check item 74 for preventing the surge of the relay is determined to be “No”, the indication list in which the indication information indicating that the relay 63 has the surge prevention failure is output. This indication list is stored in a file by the abnormal termination processing unit 22 and further notified to the designer via the network. Thus, a series of check processing ends abnormally.

As described above, in the present embodiment, since the indication list is automatically generated and notified to the designer, the checker does not need to take notes of the indication contents each time. Also, since the pointed out part is notified to the designer without relying on the checker's incorrect check memo,
Accurate notification can be made, and the accuracy of drawing inspection can be improved. In this embodiment, when the check item is pointed out (when the result of the determination of “No” is entered in the check result entry field), the checker specifies the corresponding part of the drawing (relay 63 in the example of FIG. 6). It has become. By this position designation, the indication list output unit 21 can extract the indication coordinates or the indication symbols on the drawing, and by giving the extracted information to the indication list, it is possible to more accurately notify the designer of the indication part to the designer. .

On the other hand, if there is no check item in which the “No” determination result (×) is entered, the input completion / result determination unit 18 activates the checker confirmation output unit 19. The checker check output unit 19 extracts the signature image of the checker from the checker registration information (see FIG. 3) unique to the checker code (of the checker code), and designs it on the drawing (60). It is set and output to the checker signature field (68) that is paired with the signature field (69). The normal end processing unit 20 outputs the drawing in which the checker signature image is set by the checker confirmation output unit 19, registers the checker code and the check date in the drawing attribute information of the drawing, and further, The drawing (and drawing attribute information) is saved in a file. In this way, a series of check processing ends normally.

In the above embodiment, as the information indicating the qualification range of the checker, all the designers and drawing types that the checker can handle are set in the checker registration information unique to the checker. However, the present invention is not limited to this. For example, by checking the code matching of the organization to which the checker and the designer belong, and by registering and checking the network of the organization chart (organization structure) in the checker registration library (41), the qualification check of the checker can be performed. It is also possible to loosen or tighten the criteria for (appropriate / unsuitable inspection).

In addition, as the execution result of the check using the check check list extracted from the drawing type of the drawing to be checked, the coordinates of the inspection location on the check target drawing related to each check item are designated by the checker. By storing the coordinates of the check point corresponding to each check item (or a symbol on the drawing for representing the coordinates), the history of the range checked by the checker (checking history) ) Can be left. this is,
For example, in the design related to nuclear power and the like, the history of the check and the history of the check are also left, which is a very significant effect in terms of leaving evidence of the design and the check.

In addition, since the list of checkpoints is saved in a file, when the designer revises the drawing after correcting the drawing, the recheck points on the checklist (the previous points) are automatically extracted from the checklist. Then, by restoring the check items and the coordinates on the drawing corresponding to the check items and displaying them on the screen, it is possible to greatly reduce the time required for the rechecking.

Further, in the above-described embodiment, a case has been described in which a unique check check list is prepared for each drawing type.
It is not limited to this. For example, while the drawing type (drawing type code) is composed of a plurality of keywords (in the example of the relay sequence diagram in FIG. 6, two keywords, a relay and a sequence), a sub-check checklist unique to each keyword is stored. Prepared as a relational database, based on the sub-check checklist retrieved from each keyword that constitutes the drawing type of the drawing to be checked, synthesizes a checklist specific to that drawing type, and collectively opens a window Can also be displayed. In this method, a common part can be shared between a plurality of check checklists, so that the scale of the check checklist library 42 can be reduced. An example using such a sub-check checklist will be described below.

First, the relay sequence circuit shown by the circuit diagram 60 in FIG. 6 is equivalent to the ladder sequence circuit shown by the circuit diagram 81 in FIG. This ladder sequence circuit is PL
This is realized using a C (programmable logic controller) or the like. The check checklist 82 of the circuit drawing 81 of the ladder sequence circuit includes check items unique to the sequence circuit (check items with priority to the off circuit, and check items that are common to the check checklist of the circuit drawing 60 of the relay sequence circuit shown in FIG. 6). Check items for power-off retention)
And a check item (check item for timing deviation) unique to the circuit drawing 81 (specific to the ladder circuit). Therefore, "sequence", "relay", and "ladder" are defined as keywords, respectively, and a sub-check checklist unique to each keyword, that is, a sub-check for "sequence" as shown in FIG. Checklist 91,
A sub-check checklist 92 for “relay” and a sub-check checklist 93 for “ladder” are prepared. The drawing type of the circuit drawing 60 shown in FIG. 6 is defined by “relay / sequence” composed of two keywords “relay” and “sequence”, and the drawing type of the circuit drawing 81 shown in FIG. Keywords “ladder”,
Defined by "ladder / sequence" composed of "sequence". As a result, in the check of the circuit drawing 60 whose drawing type is “relay / sequence”, the sub-check check list 91 for “sequence” and the sub-check check list 92 for “relay” are combined. A checklist 70 is created. Similarly, if the drawing type is "Ladder /
In the check of the circuit drawing 81 that is a “sequence”, a sub-check checklist 91 for “sequence” and a sub-check checklist 93 for “ladder” are combined to create a check checklist 82. Is done.

[Effects of the Invention] As described in detail above, according to the present invention, the following functions and effects can be obtained.

According to the drawing type of the CAD drawing to be inspected, a checklist specific to the drawing type that is most suitable for checking the drawing is automatically displayed in a window.
Notation was correct because it was created by the system, and the individuality of the designer did not appear on the display of the drawing, so there was a tendency for the inspector to think that the function was correct,
According to the check list displayed on the window, the check work can be performed reliably for each check item, and the check can be performed efficiently and without any omission of check.

All the check items on the check check list are checked without omission, and the signature of the checker cannot be entered unless there is no check item that is judged as "No". Thus, the reliability of the check result can be improved.

If there is at least one check item with "No" judgment in the check check list, the check item and, in addition, the problematic part in the CAD drawing to be checked that was the basis of the "No" judgment By providing a configuration in which an issue list having information (for example, the coordinate value of the indicated location or a symbol name generated based on the coordinate value) of the (indicated location) is automatically output, the design is pointed out to the designer. This makes it possible to reduce the burden on the figure inspector such as explaining and giving instructions.

Checking whether the drawing to be checked is a legitimate checker or not, and making it possible to perform the check work only if the legitimate checker, improves the accuracy and reliability of the check result. Can be achieved.
