Abstract

PURPOSE:To provide a circuit diagram input device in order to confirm whether a circuit diagram is changed into a desired circuit drawing or not. CONSTITUTION:When a circuit diagram is changed, the information on a preceding circuit diagram is stored in a storage part 22 as the stored graphic information. The information on the changed circuit diagram is displayed on a screen as the screen graphic information. A circuit connection extracting means 2 extracts the connection information out of the graphic information on the circuit diagram through a processing part 23. The stored graphic information is transferred to the part 23 and the stored connection information is extracted by the means 2. Then the means 2 extracts the screen connection information through the part 23 for the screen graphic information. A circuit connection collating means 3 collates the stored connection information with the screen connection information which are extracted by the means 2. Then the same form information is acquired if both pieces of connection information have the same form. Meanwhile the discordant area information is acquired if both pieces of connection information do not have the same form. A discordant area output means 4 outputs the discordant area through an output part 24 when the discordant area information is acquired.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit diagram input device that supports the input of a circuit diagram with a computer.

[0002]

2. Description of the Related Art In a conventional circuit diagram input device, a circuit diagram once input is changed by discovering a mistake in connection information or by coming up with a simpler circuit diagram even if the connection information is the same. In this case, the circuit diagram after the change was compared with the circuit diagram before the change, and it was confirmed by the memory of the operator who entered that the circuit diagram was changed correctly.

[0003]

However, in the above method, when the circuit diagram to be changed is input, the circuit diagram may be input incorrectly due to an operation error, or the wrong circuit diagram may be input due to misunderstanding. Even if something happens, the circuit diagram will be changed without being discovered, and as a result, it may not work properly and you may have to re-input from the beginning. It was a considerable loss of time for the person.

The present invention solves the above-mentioned conventional problems and provides a circuit diagram input device for confirming whether or not a desired circuit diagram is changed when the circuit diagram is changed.

In order to achieve this object, a circuit diagram input device of the present invention comprises circuit diagram input means, circuit connection extracting means, circuit connection collating means, and non-coincidence point outputting means. When changing the circuit diagram, the saved connection information extracted by the circuit connection extracting unit from the saved graphic information input and saved by the circuit diagram input unit and the screen changed by the circuit diagram input unit The screen connection information extracted by the circuit connection extraction means from the graphic information is connection-verified by the circuit connection verification means, and the mismatch connection information between the saved connection information and the screen connection information is obtained. The non-coincidence portion output means is configured to output.

[0006]

According to the present invention, with this configuration, when the circuit diagram is changed, the saved connection information extracted from the circuit diagram before the change,
The screen connection information extracted from the changed circuit diagram is connection-verified by the circuit connection matching means, and the mismatched portion between the stored connection information and the screen connection information can be output by the mismatched portion output means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of the circuit diagram input device of the present invention, and FIG. 2 is a diagram showing the operating principle of the circuit diagram input device of the present invention.

In FIG. 1 and FIG. 2, the circuit diagram inputting means 1 is for inputting or changing a circuit diagram, which is input from the input section 21. When the circuit diagram is changed, the information of the circuit diagram before the change is stored as the storage graphic information 11 in the storage unit 22, and the information of the changed circuit diagram is used as the screen graphic information 1.
Hold as 2 on the screen.

The circuit connection extracting means 2 is for extracting the connection information from the graphic information of the circuit diagram in the processing section 23. The saved graphic information 11 stored in the storage unit 22 is
The stored connection information 13 is extracted by the circuit connection extraction means 2 which is moved to the processing unit 23. Next, the screen graphic information 12 of the screen is
Screen connection information 1 by the circuit connection extraction means 2 in the processing unit 23
Extract 4.

The circuit connection collating means 3 collates the connection between the stored connection information 13 and the screen connection information 14 extracted by the circuit connection extracting means 2 in the processing section 23. If the two connection information have the same shape. If the isomorphism information 15 is not the isomorphism, the disagreement portion information 16 is obtained.

When the non-coincidence point output means 4 obtains the non-coincidence point information 16, the non-coincidence point information 1 is output from the output unit 24.
6 outputs the non-matching portion.

The change element extraction means 5 is not indispensable in the circuit diagram inputting method, but has an effect of shortening the processing time especially when changing a circuit diagram having a large amount of data. When the circuit connection extracting means 2 extracts connection information from the saved graphic information 11 and the screen graphic information 12, a circuit having a large amount of data requires a lot of processing time to extract the connection information. Therefore, the changed element extracting means 5 extracts the elements related to the change from the saved graphic information 11 and the screen graphic information 12, and a part of the circuit diagram including only the elements related to the change (hereinafter, referred to as a changed part of the circuit diagram). ) Is extracted, and the graphic information of the changed portion of the circuit diagram in the saved graphic information 11 (hereinafter referred to as the saved changed graphic information 19) is displayed, and the graphic information of the changed portion of the circuit diagram in the screen graphic information 12 (hereinafter, screen This is a means for extracting the modified graphic information 20). Then, in the circuit connection extracting means 2, the saved connection graphic information 19 to the saved connection information 13 and the screen modification graphic information 20 to the screen connection information 1
Extract 4. After that, the circuit connection matching means 3 is used in the same manner as before.
By comparing the stored connection information 13 and the screen connection information 14 with each other, if the same shape is obtained, the isomorphic information 15 is obtained. If the same connection is not obtained, the mismatched portion information 16 is obtained. 4 outputs the disagreement.

The handling of equal logic terminals related to the circuit connection extracting means 2 will now be described. FIG. 3 is a diagram of symbols including equal logic terminals. To input the circuit diagram, the symbols shown in FIG. 3 are registered and arranged. Here, if the symbol includes an equal logic terminal, the information indicating the equal logic terminal may be added when the symbol is registered. In the example of FIG. 3, since the terminals p1 and p2 are of equal logic, it is sufficient to add information of equal logic terminals. However, even in the case of the symbol as shown in FIG. 3, if it is desired to make the connection for each terminal one-to-one and to prohibit the exchange of equal logic, it is sufficient to add the information of equal logic terminals to the terminals p1 and p2. When the connection information is extracted by the circuit connection extracting means 2, since the connection is written in the circuit diagram, the connection information can be extracted by almost changing the format. However, if the terminals are of equal logic or Whether or not the equal logic is prohibited must be determined by whether or not the information of the equal logic is added to the symbol of the circuit diagram.

FIG. 5 is a diagram of the circuit diagram and connection information before the change of the present embodiment, and FIGS. 6 and 7 are diagrams of the changed circuit diagram and connection information. In the circuit diagram input device of the present invention, FIG. The flow of processing will be described with reference to the flowchart of FIG. In the first and second cases, the case of extracting the changed element (step 3) in the flowchart of FIG. 2 is omitted, and in the third, the case of extracting the changed element (step 3) is also described.

First, a case will be described in which the connection information that changes from the circuit diagram of FIG. 5A to the circuit diagram of FIG. 6A has the same shape. First, the circuit diagram input means 1 is used to input the circuit diagram shown in FIG. 5A (step 1), and the circuit diagram is changed to the circuit diagram shown in FIG. 6A (step 2). At this time, the saved graphic information 11 has the circuit diagram of FIG. 5A, and the screen graphic information 12 has the circuit diagram of FIG. 6A. Next, the circuit connection extracting means 2 extracts the saved connection information 13 shown in FIG. 5 (b) from the saved graphic information 11 shown in FIG. 5 (a), and the screen graphic information 12 shown in FIG. The screen connection information 14 shown in b) is extracted (step 4). Then, the circuit connection collating means 3 collates the stored connection information 13 shown in FIG. 5 (b) with the screen connection information 14 shown in FIG. 6 (b) (step 5), and FIG.
It is determined whether the stored connection information of 1 and the screen connection information of FIG. 6B have the same shape (step 6). In this case, since it is isomorphic, isomorphic information 15 is obtained. Next, the circuit diagram is updated (step 9).

Secondly, a case will be described in which there is a mismatched portion in the connection information that changes the circuit diagram of FIG. 5A to the circuit diagram of FIG. 7A. First, the circuit diagram input means 1 is used to input the circuit diagram shown in FIG. 5 (a) (step 1).
Change to the circuit diagram of (a) (step 2). At this time, the circuit diagram of FIG.
2 has a circuit diagram of FIG. Next, the circuit connection extracting means 2 extracts the saved connection information 13 shown in FIG. 7B from the saved graphic information 11 shown in FIG. 5A, and the screen graphic information 12 shown in FIG. Screen connection information 1 shown in b)
4 is extracted (step 4). Next, the circuit connection extracting means 3 performs connection verification of the saved connection information 13 shown in FIG. 5 (b) and the screen connection information 14 shown in FIG. 7 (b) (step 5), and the saved connection information of FIG. 5 (b) is obtained. It is determined whether the screen connection information of FIG. 7B has the same shape (step 6). In this case, since they are not the same shape, the mismatched portion information 16 is obtained. Then, the non-coincidence point extraction means 4 outputs the non-coincidence point information 16 (step 7). Then, it is judged whether or not the outputted non-coincidence portion conforms to the desired change (step 8). If the mismatched portion is desired, the circuit diagram is updated (step 9). If the output non-coincidence portion does not comply with the desired change, the circuit diagram is not updated and the circuit diagram before the change is returned to and the process is repeated from step 2.

Thirdly, the case where the extraction of the change element (step 3) is also introduced will be described by using the change from the circuit diagram of FIG. 5A to the circuit diagram of FIG. 7A.

First, step 1 and step 2 are the same as those in the second case. Next, the change element extraction means 5 saves 21 in FIG. 5A as the changed pattern information of the circuit diagram, changed change pattern information 19, and 23 in FIG. 7A changes the screen change pattern information 20.
(Step 3), the circuit connection extracting means 2 extracts the saved connection information 13 from the saved change graphic information 19 and the screen connection information 14 from the screen change graphic information 20 (step 4). The saved connection information 13 becomes 22 in FIG. 5B, and the screen connection information 14 becomes 24 in FIG. 7B. After step 5, the operation is performed in the same manner as in the second case.

As described above, according to this embodiment, when the circuit diagram is changed, if the connection information is the same, the circuit diagram is changed,
If they do not match, check if they are the desired ones and then change the circuit diagram.
