The operation of each unit described above is controlled by a control unit (not shown).
Is controlled by The circuit diagram comparison and correction operation of the present embodiment by the control device will be described with reference to FIG.

The flowchart shown in FIG. 2 shows a comparison and correction operation when processing is performed on a circuit diagram already stored in the database 109. When a new circuit diagram is created, comparison and correction operations are naturally unnecessary, and the processed circuit diagram is stored in the database 109 as it is.

When the comparison and correction operations are started, the control device reads the circuit information data D1 of the circuit diagram to be displayed from the database 109 based on the input content to the input device 101 (step S101), and outputs the output device 107. Is displayed on the CAD screen (step S102).

As the circuit diagram read in step S101, the backup circuit diagram of the previous version is read out at the same time, and the latest circuit diagram and the backup circuit diagram are compared as the display operation in step S102. The comparison is performed by the processing unit 111, and based on the comparison result, the display control unit 108 displays the common part with the backup circuit diagram by using the basic color A (A color or a thin line), and the backup difference part which is a different part. Is displayed in a different color B (color B or a thick line) different from color A. The steps described below are sequentially performed during the correction work.

It is confirmed whether the displayed circuit diagram is to be corrected based on the input contents to the input device 101 (step S10).
3) If the circuit diagram has been corrected, it is confirmed whether or not the difference portion is further compared and corrected (step S104).

When the read circuit diagram is not compared and corrected,
The circuit diagram correction processing unit 104 directly corrects by adding or deleting a symbol or a signal line (step S112).

If it is confirmed in step S104 that the comparison and correction are to be performed, the latest difference portion, which is a difference between the currently displayed latest circuit diagram and the backup circuit diagram, is displayed in B and used. Prompts the user to select and select the latest difference part (step S105).

Next, a backup difference portion corresponding to the latest difference portion selected and designated in step S105 is displayed on the latest circuit diagram. At this time, the connection line connecting the contact between the signal line of the backup difference portion and the signal line of the latest circuit diagram is displayed in another color C (C color, dotted line) (step S106).

Thereafter, it is confirmed whether or not the difference part is to be moved (step S107). When the difference part is to be moved, the difference part movement processing unit 10 is operated based on the input contents to the input device 101.
By (6), the position is moved while the signal line of the backup difference part is still connected (step S108).
This allows the device user to move the backup difference part to a position where it can be easily compared with the latest difference part,
Comparison work can be easily performed.

Next, it is confirmed whether or not the difference is compared and corrected (step S109). Here, as a result of the above-mentioned comparison work, when the device user inputs that he / she wants to return to the latest difference portion without validating the backup difference portion,
The backup difference portion to be returned is selected by the difference portion comparison / correction processing section 105 (step S110).

Thereafter, the display control unit 108 replaces and displays the backup difference part (step S11).
1) Return to step S103.

Here, by repeating steps S103 to S111, it is possible to partially compare and correct when there are many different parts.

As a result of the check in step S103, if the circuit diagram is not corrected, if the circuit diagram is corrected in step S112, and if the result of the check in step S107 does not move the difference portion, or if step S1
As a result of the confirmation in step 09, when the comparison and correction of the difference portion are not performed, the currently displayed circuit diagram is stored in the database 109 by the file input / output unit 110 as the latest circuit diagram (step S113). After that, when the storage processing of one or all circuit diagrams is completed, the symbol between the backup circuit diagram and the latest circuit diagram is checked by the circuit diagram comparison processing unit 111 together with other items in the sheet check or the sheet check. Differences such as and signal line connections are checked (step S114).

As a result of the above check, the difference part storage circuit information data D2 is extracted. The information D2 is also stored in the database 109 for use in the next editing work (step S115), and the difference part data and the latest The circuit diagram data obtained by combining the circuit diagram data is stored as the latest comparison circuit diagram (step S116).

Next, a method for comparing and correcting circuit diagrams according to an embodiment of the present invention will be described with reference to FIGS.

The circuit diagram is read on the CAD screen as shown in FIG. 3 by the circuit diagram reading operation in step S101.

In this display, the display control unit 108 uses the basic color A
(A color, thin line), and if there is a backup difference portion, the backup difference portion is displayed in another color D (D color, thick line).

Thereafter, the circuit diagram correction processing unit 104
In the read circuit diagram, the symbol 2 and its associated signal line are deleted (difference portions 201 and 301), the symbols 3, 4, and 5 are deleted, and the symbol 9 is added to change the wiring (differences). Parts 200, 300), replacing symbol 7 with symbol 10 (difference parts 202, 3)
02) Make corrections to the circuit diagram.

The modified circuit diagram shown in FIG. 4 is stored as the latest circuit diagram of version 2 by the file input / output unit 110.

When the input of one or all of the circuit diagrams is completed by the circuit diagram comparison processing unit 111, the circuit diagram before correction of the latest circuit diagram is performed together with other items in the in-sheet check or inter-sheet check. Differences between a certain backup circuit diagram and the latest circuit diagram, such as symbols and signal line connections, are checked.

Here, the backup difference part is stored as the difference part circuit information data D2. The circuit diagram data obtained by combining the data 200, 201, 202 of the backup difference portion, the data 300, 301, 302 of the latest difference portion and the data of the latest circuit diagram are stored as the data of the latest comparison circuit diagram.

Next, the latest comparison circuit diagram is read on the CAD screen. At this time, the latest circuit diagram is read by default.

When the latest circuit diagram is read, the common part of the latest circuit diagram and the backup circuit diagram is displayed in the basic color A (A color, thin line) by the display control unit 108 as shown in FIG. The latest difference portion that is different from the backup circuit diagram in the figure is displayed in another color B (B color, bold line).

When the apparatus user who has confirmed the latest difference portion wants to return the latest difference portion 200 to the backup difference portion 300, the user inputs that fact, and the difference portion comparison / correction processing section 105 causes the B color in the latest circuit diagram to be displayed. The latest difference portion 200 indicated by the symbol can be selected and designated.

When the latest difference portion 200 is designated, FIG.
Is displayed by the display control unit. Here, when the apparatus user gives an instruction to select the backup column and display the backup difference portion 200 on the latest circuit diagram, the backup difference portion 200 is displayed in a different color D (D color, bold line) and the backup difference portion. The connection line that connects the contact of the signal line of
(C color, dotted line) is displayed on the circuit diagram.

When it is desired to return to the backup difference portions 201 and 202 for each of the latest difference portions 301 and 302, similarly, the difference portion circuit information data D2 and the display control section 108 as shown in FIG. , 202 are displayed.

When it is difficult to see the latest difference portion 300 and the backup difference portion 200 when comparing them, the difference portion movement processing section 106 causes the backup difference portion 200
Can be freely moved to a position where comparison is easy while the signal lines are connected.

The latest difference portion and the backup difference portion can be returned alternately many times.
If the user wants to return to the latest difference portion 300 without validating 00, the device user needs to return the backup difference portion 20 to be returned.
Select and specify 0.

In response to the selection, the display control unit 108
Replaced with backup difference part 200 and latest difference part 3
00 is displayed in another color B (B color, bold line) as shown in FIG.

As a result of the above editing work, a circuit diagram as shown in FIG. 7 is edited and displayed.

The database 109 stores the latest circuit information data D1 shown in FIG. 8 together with the difference part circuit information data D2 extracted by the circuit diagram comparison processing unit 111 by the file input / output unit 110.

[0052]

As described above, according to the method of correcting and comparing the CAD input circuit diagram of the present invention, the difference between the circuit diagram before correction and the circuit diagram after correction is confirmed on a single circuit diagram. Because it is possible, not only the person who input the circuit diagram, but especially before the person who input the circuit diagram corrects, diverts, or uses the circuit diagram, when checking the correction contents and correction points This has the effect of saving time and labor for comparing the last two circuit diagrams.

Further, there is an effect that the time and labor for writing a comment indicating the corrected portion or the content of the circuit diagram can be reduced.

Further, it is possible to particularly emphasize a corrected portion of the circuit diagram, that is, a portion of the circuit diagram where a defect has occurred, and there is also an effect that a defect is confirmed and a defect is prevented from being overlooked.

Also, not all the data before the circuit diagram correction,
Since only the data relating to the difference part needs to be stored, there is also an effect of saving the disk capacity.

Further, when it becomes necessary to return to the circuit diagram before the correction, the operation of re-selecting the deleted symbols, rearranging them, rewiring the signal lines, and selecting the added symbols by avoiding them Since the correction can be performed only by inverting the difference portion without performing the deleting operation, there is also an effect that the time for the correction is greatly reduced.
