Abstract

PURPOSE:To perform a processing at high speed by carrying out a data value deletion processing and a data value deletion preventing processing to specific other data by a data renewing means based on auxiliary data deciding whether the specific other data relating to the data is deleted or not. CONSTITUTION:Every design data 6, it is added to a value of the result of the design, the name or the like of the data formed by using the value is stored in a storing means 4 as the auxiliary data, and the auxiliary data 7, 8 is used when the value of the data is changed or deleted. Namely, when the data formed by using the value is deleted by using the deleting auxiliary data 7 and since unnecessary data may be deleted according to the case only by that, the data used when the value is formed every data is stored as the deletion preventing auxiliary data 8 and the deletion is prevented by using this. Thereby, by deletion processing can be executed at high speed in proportion to all the number of the data without increasing the processing time even when the number of the data is increased.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a design support system using an electronic computer, and is particularly suitable when design data once determined is likely to be changed later. It is related to a design support system. [Background of the Invention] With advances in computer technology, CAD systems that use computers to support design have been developed and are in use. In such a CAD system.

In general, the design results are stored as design data in a storage device within a computer, and are then output in a diagram form and displayed on a display device such as an 1T.

The user uses this output display result to modify the design data if necessary, and confirms the modification by displaying the output on the display device again.

By the way, in actual design work, there are many repetitions of modification of design data and display processing to confirm the modification results, so it is essential for CAD systems to be able to carry out this process efficiently. . For example, A, B,
Assuming that there are three sets of design data called C, and B is to be modified, if there are no measures taken, the design data for A and C will be determined to be invalid as B is modified. .

Only B is newly output and displayed on the display device. A
In order to output and display C and C again, an output display request is required from the user.

In order to avoid this extra output display request,
Japanese Patent No. 114265 proposes a method of storing dependencies of design data as auxiliary data indicating the number of design changes. According to this, if the three sets of design data are created first in the order of A→B-pC, even if B is modified, A
remains valid. That is, only C placed after B disappears from the output display of 1 display 4 & position.

However, in this case, only the number of design changes is used, so there is a lot of design data.

And if there are multiple dependencies between them, a decrease in efficiency is unavoidable. For example, in the above example, if C is A
, is design data determined independently without depending on B, then even if B is modified, C remains valid and should therefore be output and displayed.

In this way, when changing design data, design support has the ability to efficiently determine the necessary and sufficient design data to be deleted from the output display of the display device, taking into account the dependencies with other design data. Although the system has not yet been realized, this is the reality.

[Purpose of the invention]

An object of the present invention is to efficiently change or delete design data once determined, taking into account the existence relationship with other design data, thereby reducing the burden on the user. There is a VC that provides a design support system that can reduce the number of requests and speed up change/deletion processing.

[Summary of the invention]

For this purpose, the present invention stores, for each design data, in addition to the value obtained as a result of the design, the name of the data created using the value as auxiliary data. This is what I did. A vAK whose data value has been changed or deleted uses the auxiliary data. In other words, data created using that value is deleted using auxiliary data for deletion, and depending on the case, unnecessary data may be deleted if this is done alone.

FI the data used when creating the value for each data
Store it as auxiliary data to prevent IJ removal.

This is used to prevent deletion.

[List of inventions]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below using drawings. 5
Figure g1 shows the configuration of an example of the design support system according to the present invention.

In FIG. 1, reference numeral 1 indicates that each design data is entered by an iodine means, which may be a program running on a computer. 2 may be a data processing means for processing data according to a given instruction, or may be a program running on a computer. 3 is a data display means for displaying data, and may be a display terminal connected to a total of 4 terminals. 4 is a data storage means 69 for storing design data. A database on a computer storage device may be used. 5 may be a data update means for storing data) or a program running on a computer. 6 is design data stored in the data storage means 4. Reference numeral 7 indicates auxiliary data for data value deletion which is stored in the data storage stage 4, and may be a table of names of data created using the data. Reference numeral 8 denotes auxiliary data for preventing deletion of data values stored in the data storage means 4, which may be a unified table of data names used when creating the data values. Reference numeral 9 is essential for data value deletion processing in the data updating means 5, and may be a program running on a computer. 10 is data value deletion prevention processing in the data updating means 5, and this may also be a program running on a computer.

The configuration is as above, but to explain the processing procedure in this system using a simple example, first, the data processing means 2 is given the following design data 11 [setting ID]. Suppose that

“Substitute data AlCl” ・・・・・・・・・
・・■ “Substitute data BvcA+1” ・・・
...■ "Substitute 3 to data C" ...
. . . ■ Such instructions may be given sequentially in an interactive format, or may be given in the form of an executable program stored in advance in the computer.

Now, when the data processing means 2 receives an instruction to set a value in the design data, it instructs the data storage means 5 to store the data value.

As a result, the data updating means 5 stores the data value in the data storage stage 4 as shown in FIG. 3(A) according to the processing procedure shown in FIG. 2(A). If the process (2) is instructed in a state where no data value is stored, the substitution process shown in FIG. 2(A) is executed and l is stored as the value. Next, when the process (■) is instructed, the middle insertion process (5g2 (A)) is executed and 2 is stored as the value. At the same time, the name of data A used when creating value 2 of B is stored in the prom item as auxiliary data 7 for preventing data value 8u from being removed.

Further, in data A, data name B is stored in item 10 as auxiliary data 8 for data value deletion. Thereafter, the process up to (2) is executed in the same manner, and the contents stored in the data storage means 4 when the process (2) is executed are shown as 41 in FIG. 3(A).

In this $:, state I, further “correct A to 2” ・・・・・・・・・■
If such an instruction is processed by the data processing means 2, in this case, the stored contents of the value bTo term and prom term of data B are first deleted by the deletion process shown in Figure 5g2 (A), and then the stored contents of the value bTo term and prom term in Figure 2 (A) are deleted. Due to the assignment process in A), 2 is stored in the 9AO value. As a result, the contents stored in the data storage means 4 are transferred from state 1 to state 2.

Also, the condition shown in Figure 3 (A)! In u41, ``0 relationship is 8
If an instruction such as "Divide B by 4 to 1 is correct" is processed, then in this case first
The name B is deleted from the 9AOrO term by the deletion prevention process shown in FIG. As a result, state 3 shown in FIG. 3(A)
Furthermore, in this state 3,

“Correct A to 2” ・・・・・・・・・
If an instruction such as 0 is processed, in this case, 2 is simply stored in the 9AO value by the substitution process shown in FIG. 2(A)K.

The processing procedure has been explained in detail above, but its characteristics can be explained in the third section.
The following can be summarized with reference to Figure (A).

(1) When the value of the design data is changed on the way (when the instruction in (■) is processed), only the data B, which becomes invalid due to the relationship in (2), is deleted and the data C is saved.

(11) Furthermore, even if data A is changed by processing the instruction in (2) after data B is changed in the process (2), data B will not be deleted.

qlo Furthermore, since it is not necessary to check all the contents of the data storage means 4 in the processing by the data updating means 5, the processing time does not increase in proportion to the number of data.

What are the process characteristics of these design data changes?

The change is reflected in the display content on the data display means 3. Therefore, the content of the process can be confirmed from the displayed content.

What is displayed below? For example, if two types of lJ are revealed.

As a first display example, it is conceivable to display the data value simply as numerical data in the form of an arrow.

The processing procedure including the display in this case is shown in Figure 2 (B)K.
:show. In FIG. 2(B), deletion processing.

The deletion prevention processing and substitution processing are similar to those shown in FIG. 2(A). The display process after these processes is for optically displaying the values of the data stored in the data storage means 4 in a table format. FIG. 3(CB) shows examples of display states f11-4 on the 081 screen corresponding to states 1-4 shown in FIG. 3(A).

In the display process, for state 1, the data person is first selected as undisplayed data, and the data master is displayed on the left side of the screen of the data display means 3, and the 1st shift 1 is displayed on the right side of the screen. Next, data name B is displayed on the left side of the screen, and value 2 is displayed on the right side of the screen. Finally, data name C is displayed on the left side of the screen, value 3 is displayed on the right side of the screen, and then the frame for table 1 is displayed. Furthermore, in display state 2 corresponding to state 2, in this case not only the value of data A has changed, but also the display of data B has disappeared.

Furthermore, in display state 3 corresponding to state 3, only the value of data B is displayed. Yet another state 4
In the corresponding display state B4'IC, compared to display state 3, only the value of A has been modified, and the display of the value of B has not changed at all.

The first display example is as described above, but as a second display example, it is possible to use the data value as the X coordinate and display the name of the data on the coordinate indicated by the value. The processing procedure at this point is shown in FIG. 2(C). In FIG. 2(C), the deletion processing, 11" removal prevention processing, and substitution processing are similar to those shown in FIG. 2(A), but in the 1 display processing, the data stored in the data storage means 4 is The button is used to display the value as the X coordinate and the data name. FIG. 3(C) shows display states 1 to 4 on the CRT screen corresponding to states 1 to 4 shown in FIG. 3(A).
This is an example. According to this, for the state IK, data A is first selected as undisplayed data, and then the data master selects X on the display screen of the data display means 3.
It is displayed at the coordinate l position. Next, data B is selected as undisplayed data, data name B is displayed at the X coordinate 2 position, and finally data name C is displayed at the X coordinate 3 position.

Furthermore, in display state 2 corresponding to state 2, while the display position of the data master has changed, data name B is no longer displayed. Furthermore, in display state 3 corresponding to state 3, only the display position of data name B has changed. Furthermore, in display state 4 corresponding to state 4, compared to display state 3, only the display position of A has changed, and the display position of B has not changed at all.

Now, in order to clarify the extent of the effect of the present invention, the processing results of two conventional known examples are shown in FIGS. 4 and 5.
As shown in the figure. Of these, the one shown in FIG. 4 corresponds to FIG. 3(A). This figure shows the status of each processing result based on Japanese Patent Application Laid-Open No. 58-114265. As shown in the figure, when data is updated, all data created after that data is deleted in the order in which the data was created. That is, when the above-mentioned instructions ①, ②, and ② are carried out, as shown in FIG. 4 as state 1, the status 1. In order: 1. Value 2 as data B. The order is 2. The value 3 is stored as data C, and 3 is stored as the order.

When the instruction (2) is processed in this state, the order has a higher order than the data person's order, as shown in state 2.

Data A and data B were also created later.

The value of C is deleted and the value of data A becomes 2. The order is updated as 4. Furthermore, when the instruction ■ is processed in state 1, as shown in state 3, the value of data C created after data B is deleted, and the value of data B is changed to 2. It is updated as order 4. Furthermore, when the instruction (2) is processed in state 3, the values and order of data B created after data A are deleted, as shown in state 4.

As is clear from comparing each of states 1 to 4 shown in FIG. 3(A) with each of those shown in FIG. is deleted, and it can also be seen that in state 4, the value of data B that is irrelevant to the modification is also deleted. In addition to this problem, in the process related to the known example, all data contents are checked and the order of creation is compared with that of the target data, so the processing time increases in proportion to the number of data. It is something. Of course, the display contents on the data display means 3 will also be different reflecting the difference between FIG. 3(A) and FIG. 4.

For example, data C is not displayed in states 2 and 3 shown in diagram i43 (C), and data C is not displayed in state m4.
is no longer displayed. In this known example, the data value deletion prevention auxiliary data according to the present invention and the related data value deletion prevention processing are omitted.

In FIG. 5, state 1 shows the processing result after the instructions ■, ■, and ■ have been processed, and state 2 shows the processing result after the instruction ■ has been processed in state 1.

Up to this point, the same processing results as those according to the present invention have been obtained. However, the processing result after the instruction has been processed in state 1 is shown as state 3, but in state 3, even though data B has become unrelated to data A according to instruction Data B is registered in item 10 of A as data for data value deletion. To clear this, you must check the contents of item 10 of all data. As a result, processing time increases in proportion to the amount of data. In order to avoid this increase in processing time, as shown in state 3, if the instruction ■ is processed without clearing the data AOTO item, even data B that does not need to be deleted will be deleted. be.

In other words, if we compare state 4 shown in FIG. 3(A) with that shown in FIG. becomes undeniable.

This difference is reflected in the display contents of the data display means 3. For example, in display state 4 shown in FIG. 3(C), C is displayed, but in the corresponding display state shown in FIG. 5, C is not displayed.

Although the basic conjunction is the same as that shown in FIG. 1, the processing procedure is different as shown in FIG.

That is, as shown in FIG. 6, the name of data created based on the value of the data is stored as auxiliary data for data value deletion, which is similar to the embodiment described above. However, in this embodiment, together with the auxiliary data for data value deletion, the order in which the data was created is stored as auxiliary data for preventing data value deletion.

Assume that the above-mentioned instruction [F] is processed in a state where equivalent data is not stored in the data storage means 4.

The substitution process shown in FIG. 6 is executed, and as shown in FIG. 7 as state 1, 1 is stored as the data AO value and 1 is stored as the order. Next, when the instruction (3) is processed, the substitution process shown in FIG. 6 is executed again, and 2 is stored as the value of data B and 2 is stored as the order. In this case, in addition to the 10 items of data A,
The data name B is stored as auxiliary data for data value deletion, and the order 2 of B is stored as auxiliary data for data value deletion prevention in the form of a list (B, 2).

In this friend, the value 3 and the order 3 are stored in the data C by processing the instruction (3).

Now, if instruction (2) is processed in such state 1, the order 2 of data B in the list stored in the ro term of data A and the +p The order 2 stored in the o term is compared, but in this case, both are 2, so the deletion process deletes the value of data B, and the substitution process deletes the value of data A.
2 is stored as the value, and 4 is stored as the order.

Furthermore, if the instruction (2) is processed in state 1, 3 is stored as the value of data B and 4 is stored as the order by the substitution processing shown in FIG. State 3 shows the processing result at this time.

Furthermore, when the instruction (2) is processed in this state 3, the order of data B in the list stored in the 'rO term of data A is determined by the deletion prevention process shown in FIG.

The order 2 stored in the To term of data A is compared. In this case, since they are different, deletion processing is not performed and data A (DTO
The list stored in the item is cleared.

Even in the second embodiment of the processing procedure described above, when data is changed midway through the process, data that becomes invalid due to the change is deleted, while irrelevant data is deleted in the process. There isn't.

Furthermore, the processing time does not increase in proportion to the amount of data. That is, it has the same features as features (1) to (1) of the first embodiment.

In this embodiment, the creation order is used to prevent gator value deletion, but any arbitrary value can be used as long as it can be used to determine whether to prevent deletion by giving a different value when updating the value for the same data. It can be a single numeric character or a symbol. Furthermore, in both of the two embodiments described above, only the data value is changed, but by omitting the one-substitution process, it can be used as is to delete the data value.

Finally, to explain the application of the present invention to a specific system design, when the design target becomes large-scale, the number of simple design data as shown in the instructions cited as an example (L~■) is 103~104. In such a case, a method may be adopted in which the design data is divided into groups and the processing results are stored at the level of each group as shown in @Figure 3 (A) or Figure 7.For example, When the object of design is a plant, there are two possible grouping levels: system and equipment.In this case, first, the processing results are stored for each equipment as shown in Figure 3(A)K. Processing results are similarly stored for each primary valley system, but in that case, the device name is used instead of the data name, and when storing the processing results of the top level novel, the system name is used as the data name. In other words, the processing results are stacked in three layers. It is sufficient to store auxiliary data for deletion/uncutting at that level in the 20th term and the prom term of each layer.

〔Effect of the invention〕

As explained above, according to the invention, when design data is changed or deleted midway through, only data that becomes invalid due to the change or deletion can be removed.

Data unrelated to the change will not be divided by Al1. Further, even if the number of data increases, the deletion process can be performed at high speed without increasing the processing time proportionally because the data is the entire data. As a result, the display device of the design support system has only the necessary and sufficient display for K each time design data is changed or deleted, thereby realizing an efficient CAD system that can reduce the burden on the user. There is an effect.
