Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is an apparatus for automatically correcting drawing data, more specifically, a device for automatically correcting drawing data, and more specifically, a device for automatically correcting drawing data in a magnetic tape (PC tape) on which sequence circuits in a programmable controller (PC) are written. The present invention relates to an automatic drawing correction device that automatically corrects and obtains new drawing data.

Conventionally, a sequence circuit in a PC has been processed according to the flow shown in FIG. That is, first
A drawing data b is output by designing a drawing using a CAD system, and then a drawing d is created by drawing c from the drawing data b. On the other hand, based on the drawing data b, a PC tape f is output by PC tape creation e, this PC tape f is read into a PC (control device) g at the site, and the controlled equipment h is actually operated to perform adjustment work. Let's do it. If there is a problem at this time, the sequence circuit in the PC can be changed directly on the spot. When the adjustment is completed in this way, the sequence circuit with the changed contents of the original drawing data b is stored in the PC, and the changed drawing data is also recorded on the PC tape i.

In this way, since the sequence circuit in the PC is directly changed on site, the changes will not be reflected in the original drawing d. Therefore, after the change
It is necessary to complete a new drawing k by making drawing corrections j according to the contents recorded on the PC tape i. Conventionally, drawing correction j has been performed manually, which has the problem of requiring a long time and causing many correction errors.

Recently, a device has been put into practical use that converts the drawing data on a PC tape into a drawing on a printer, etc. However, since this device uses only the PC tape as an information source, only the logic circuit part inside the PC can be drawn. Therefore, the circuit ancillary information (drawing ancillary information) such as electrical equipment codes and annotations necessary for the drawings is not specified, and there is the inconvenience that these must be manually input one by one. In addition, since the drawing information on the PC tape is converted into a drawing as is, it is not possible to immediately determine whether the drawing has been changed or not, and extra effort is required to extract the necessary drawings. This may make the correction work even more troublesome.

The present invention has been made in view of the above-mentioned conventional problems, and makes it possible to automate the work of drawing correction j shown in FIG. The purpose of this invention is to provide an automatic correction device.

The purpose of this is to compare the drawing data created by the CAD system at the time of design with the drawing data in the new PC tape created based on the drawing data, and to identify the changes. a comparison/extraction unit that extracts, an automatic adding unit that reads out the drawing ancillary information at the changed part from the drawing data before the change based on a match of pre-assigned addresses, and adds it to the data after the change; This is achieved by an automatic correction device including an automatic drawing correction section that replaces the changed portions of the drawing data with the changed data.

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

FIG. 1 is a block diagram showing the basic configuration of an automatic drawing correction apparatus according to the present invention. In the figure, 1 is the drawing data created by the CAD system (corresponding to b in Fig. 6), and 2 is the drawing data 1.
The drawing data in the new PC tape (corresponding to i in Figure 6) is created by changing the content of the PC tape created based on the above data. 3 and 4 are data conversion units that convert the drawing data and PC tape data into intermediate data. , 5 and 6 are intermediate data of the drawing before the change and the contents of the PC tape after the change, 7 is a comparison section for sequence circuits (hereinafter simply referred to as circuits) and a section for extracting changed parts, 8 is data related to circuit changes, and 9 is the circuit Reference numeral 10 indicates an automatic drawing correction unit for attached information, and 11 indicates automatically corrected drawing data, and arrows indicate data flows.

Next, the functions of each part will be explained in accordance with the processing order. Since the data structures of the drawing and the PC tape are different, the data converters 3 and 4 are parts that convert the data into a data structure that is common to both and is easy to process later. As a result of the execution of the data converters 3 and 4, intermediate data 5 and 6 of the circuit before and after the change are created. The comparison extraction unit 7 compares the two circuit data and obtains the result as change information 8. The circuit attachment information automatic adding section 9 automatically adds circuit attachment information such as electrical equipment codes and annotations to the circuit changed based on the change information 8 using the drawing data 1 before the change. Finally, the automatic drawing correction unit 10 corrects the drawing data 1 before the change based on the change information 8 to obtain the drawing data 11 after the change.

The flowchart of the comparison/extraction section 7 is shown in FIG. 2. That is, data is received at 12, and at 13 two intermediate data 5 and 6 are compared regarding the increase/decrease and order of coils, and the results are converted into 1.
4, it is stored as change information 8. This allows us to use the coil as a key to check whether there are any major circuit changes. 15 compares circuits for one coil. If there is a difference as a result of the comparison, it is assumed that the circuit has been changed and stored as change information in steps 16 and 17. Furthermore, perform steps 15, 16, and 17 for all circuits, and when all circuits are completed, check step 18 for detailed circuit changes.
Data is transmitted from 19.

Further, a flowchart of the automatic provision section 9 of circuit ancillary information is shown in FIG. 3. First, 2
It is determined whether the data received at step 0 corresponds to a part where the circuit has been changed based on change information 8 at step 21. If the circuit has been changed, in step 22, circuit attached information (electrical equipment code, annotation, etc.) having the same address value is extracted from the old drawing data 1 and given to the circuit. Then, steps 21 and 22 are performed for all circuits, and when all circuits are completed, data is transmitted from 23 and 24. However, if you want to add a circuit that is not in the drawing data 1 before the change, it cannot be added automatically, so you must input it separately.

Furthermore, a flowchart of the automatic drawing correction section 10 is shown in FIG. First, data is received at 25, and 2
In step 6, it is determined whether the circuit has been changed based on change information 8. If the circuit has been changed, 2
In Step 7, replace the drawing data of that part with new circuit information (PC tape information with additional circuit information such as electrical equipment codes and annotations). Then, steps 26 and 27 are performed for all circuits, and when all circuits are completed, data is transmitted from 28 and 29.

FIG. 5 shows an example of changes in a drawing before and after correction by the automatic correction device. In the same figure, 31 is the design drawing drawn based on drawing data 1 (corresponding to d in Figure 6), and 32 is the design drawing recorded on the PC tape (corresponding to f in Figure 6) before the contents are changed. 33 is the drawing recorded on the PC tape (corresponding to i in Fig. 6) after the contents have been changed by on-site adjustment work, and 34 is the revised drawing corrected by this automatic correction device (Fig. 6). k
(equivalent to) respectively. From this, in the design drawing 31, an electrical equipment code 35 is attached to the electrical equipment at each address, and annotations 36 such as "Simentan" and "Jigushime" are attached to each circuit, but the PC tape f From the drawing 32 in FIG. On the other hand, in drawing 33 in PC tape i after the change, address 4000 is added to the second circuit.
A contact point 37 is added. In this case, in the corrected drawing 34 corrected by the present automatic correction device, the electrical equipment code 35 and annotation 36 are added to the electrical equipment including the changed contact 37.

As explained above in detail, the automatic drawing correction device according to the present invention extracts and automatically corrects the changed parts of the drawing data in the PC tape, and generates new drawing data including drawing ancillary information. This has the effect of greatly reducing the number of drawing correction man-hours, preventing mistakes, and significantly improving the reliability of corrected drawings.
