Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a computer-aided design device, and in particular, evaluates the validity of the layout of an object based on design standards after layout, and displays the result. , relates to an evaluation support device suitable for interactively modifying the layout of an object.

[Conventional technology]

Conventional computer-aided design devices (hereinafter referred to as CAD devices) have a display screen that displays layout objects,
An input device that generates coordinate value data based on the result of specifying an arbitrary position on a display screen, and a point at a position specified by a designer.

It utilizes an interactive technology that displays nine line segments, characters, etc., and writes the coordinate values of their positions and the data of the display contents into a storage device.

Recently, a new technology has begun to appear that goes one step further and incorporates a new concept called design standards, and allows layout design to be done interactively based on this concept. This reads the related design standard data based on the design target code, displays the design drawing and the corresponding design standard on the display screen, and in the design drawing, graphical constraints obtained from the design standard are applied. It is also displayed to support layout dialogue design.

This method is certainly very effective in eliminating design mistakes and increasing reliability, but it is just a means of dialog processing, and automation has not been taken into consideration much. Furthermore, the current situation is that conventional designers have drawn up such design standards in their heads in advance and proceeded interactively to a certain extent using "kan" techniques. Unfortunately, it was still impossible to automatically perform designer-level layout planning using a computer.

Against this background, layout planning is left to an automatic layout system that allows designers to easily interact with each other. After layout, the validity of the layout of the object is automatically evaluated based on the design standards, and the There has been a need for a method for partially modifying the layout through dialogue depending on the results.

[Problem that the invention seeks to solve]

The above conventional technology is mainly based on interactive CAD, does not give much consideration to automation of design, takes time to input,
There were problems such as poor responsiveness and failure to fully reflect design standards.

The purpose of the present invention is to leave the layout planning part to the designer's interactive processing or simple automatic layout, automatically evaluate the object after layout, and partially modify the layout interactively depending on the results. An object of the present invention is to provide a layout evaluation support device.

[Means for solving problems]

In order to achieve the above object, the present invention constructs layout object data and design standard data in an external storage device, and uses the layout evaluation object as a keyboard.

Instructions are given using an input device such as a tablet or mouse, and the evaluation conditions of the evaluation object are set from the design standard data read for each layout point of the evaluation object, and a function is called and executed to check each evaluation condition. To provide a layout evaluation support device that evaluates a layout based on the evaluation points, displays the design standard only when it violates each evaluation point, notifies an operator of the evaluation result, and partially corrects the layout interactively.

[Effect]

The layout data and design standard data of the layout object are stored in an external storage device in advance. Instructing the display screen of the layout object is done by specifying the display range using the input device and retrieving the data from the external storage device.

When an evaluation target object is specified using the input device, its layout data is retrieved and each layout evaluation point is set.

Of all the design standards read from the external storage device, only those relevant to the evaluation target are selected and set as evaluation conditions. As a result, a function that checks the evaluation conditions for each evaluation point is called and executed one by one, and if there is a violation, the content of the design standard that was violated is displayed on the display screen. Therefore, the designer can immediately visually see which evaluation points and which design standards the evaluation target object violates.

As a result, it is only necessary to partially correct the layout in areas that are not in good condition, so that an appropriate layout plan can be efficiently executed. Furthermore, since a correct layout plan is made in accordance with the design standards, design mistakes are not made.

[Example] Hereinafter, an example of the present invention will be specifically described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of an embodiment of a layout evaluation support device according to the present invention. Image display device 2 for displaying character 2 images on display device 1
reads the coordinate data of the drawn image from the image data storage device 3. In the image data storage unit w3, graphic display data of the layout object, design standard data, and its schematic diagram display data are written as drawn image data. The arithmetic processing device 5 that executes these processes includes an arithmetic unit 5 a + a processing procedure storage unit 5 b, an intermediate data storage unit 5 c, an input unit 5 d, an image data output unit 5 e, a layout data output unit 5 f, and a layout data search code output.

FIG. 2 shows an example of the overall processing procedure executed by the arithmetic processing device 5. Hereinafter, the operation of the apparatus of the present invention will be explained according to the processing procedure shown in FIG.

First, in the first step 8 of the processing procedure, layout data of the layout object is read from the layout data storage device 6 via the layout data input section 5h. Third
The figure shows an example of the processing procedure in the first step 8.

The data is written to the intermediate data storage section 5c. Next, these codes are taken out from the intermediate data storage section 5c and sent to the layout data storage section M6 via the layout data search code output section 5g. Based on the sent plant, building, and floor codes, all layout objects containing these codes are searched. From the input device 4 (e.g., keyboard, joystick, tablet, etc.), the plant code r
2F-44, building code “T”, floor code “IF”
If you enter , the frame (wall) to be searched.

FIG. 4 shows an example of a storage format of layout data of layout objects (columns, beams, floors, etc.) in the layout data storage device 6. Similarly, the storage format of equipment layout objects is shown in Figure 5, the storage format of nozzle layout data connected to it is shown in Figure 6, and the storage format of subdivision area (equipment drawer space, aisle space, etc.) layout data is shown in Figure 5. It is shown in Figure 7. Further, FIG. 8 shows a storage format of attribute data of a piping layout object to be layout-evaluated, and FIG. 9 shows a storage format of the layout data.

Furthermore, the layout data of the searched layout object is taken out from the layout data storage device 6 and written into the intermediate data storage section 5c via the layout data input section 5h.

In the second step 9, the layout object is displayed on the display device 1 based on the layout data read in the first step 8. An example of the processing procedure in the second step 9 is shown in FIG.

First, the layout data of the layout object is retrieved from the intermediate data storage section 5c. Next, coordinate values and dimensions are selected from the layout data of each layout object taken out, and these are written into the image data storage device 3 via the image data output section 5e. Further, coordinate data of the menu area is read from the layout data storage device 6 via the layout data input section 5h, and further, these data are written into the image data storage section 3 via the image data output section 5e. FIG. 11 shows an example of menu area coordinate data stored in the layout data storage device 6 in a table format. After executing the second step 9, the image display device 2 reads the drawing image data of the layout object and the coordinate data of the menu area written in the image data storage unit W3, and executes an image to be displayed on the display device 1. An example is shown in FIG.

In the third step 10, design standard (layout standard) data for setting evaluation conditions is read. An example of the processing procedure of the third step 10 is shown in FIG. first,
All the design standard data stored in the design standard data storage device 7, their character display data, and their corresponding schematic diagram display data are read through the design standard data input section 51. Next, all the read data is numbered and written into the intermediate data storage section 5c. FIG. 14 shows an example of the contents of typical design standards and a schematic diagram thereof.

These design standards must be observed when designing a layout, and are applied as evaluation conditions to check the validity of the layout after the layout is completed. An example of the storage format of the design standard data stored in the design standard data storage device 7 is shown in FIG.

In the fourth step 11, the input device 4 is used to designate the evaluation object whose layout is to be evaluated. Fourth step 1
An example of the processing procedure No. 1 is shown in FIG. First, using the input device 4, the user instructs the "line designation" item in the menu area. The input device 4 here is, for example, a two-dimensional coordinate input device such as a stick or a mouse. From here, you will enter the layout evaluation execution mode. Next, using the input device 4, the name of the evaluation object whose layout is to be evaluated is input. The input device 4 here is, for example,
It's a keyboard. An example in which the rHD-3J line is specified using the input device 4 will be described below. Next, the name of the evaluation object is written into the intermediate data storage section 5c via the input section 5d.

A layout object having the same code as the name of the evaluated object is retrieved, and its layout data is retrieved from the intermediate data storage section 5c. In this embodiment, the layout data of the piping of the line code rHD-3J shown in FIG. 9 is extracted. Further, layout evaluation point coordinates are selected from among the layout data and written into the image data storage device 3 via the image data output section 5θ. Each route point constituting one line is used as a layout evaluation point. In this example, route No. 1 (A-12
) to No. 18 (N21-BOO3-1) are set as layout evaluation points. The image display device 2 after executing the fourth step 11 reads the coordinate data of each layout evaluation point written in the image data storage device 3, and displays an example of an image in which each layout evaluation point is displayed on the display device W1. It is shown in Figure 17.

In the fifth step 12, only the design standards related to the object to be evaluated are extracted from all the design standard data read in the third step 10, and these are set as layout evaluation conditions. An example of the processing procedure of the fifth step 12 is shown in FIG.

The name code of the evaluation object is retrieved from the intermediate data storage section 5o. Next, items and values of attribute data including the name code of the evaluation object are retrieved from the intermediate data storage section 5C. In this embodiment, the items and values of the attribute data of the line code rHD-3J shown in FIG. 8 are extracted. First, from among the design standard data stored in the intermediate data storage section 5c, one whose condition data includes a pair of attribute data item and value is selected. In this example, based on the attribute data of "rHD-3", this evaluation target object is a pipe and the temperature is high (
120℃), the system is Hr), the 9-caliber is 400, and the intermediate equipment is ■-03, the type of which is a pressure regulating valve, as attribute data, so the design standard data shown in Figure 15. Among them, design standard No. 8, 22.42 is selected as including all the condition data. Furthermore, the selected design standard data number, evaluation items, and conclusion data are set as evaluation conditions for the evaluation object, and are written into the intermediate data storage section 5c together with the name code. In this example, the evaluation conditions for the evaluation object called "Line code r HD-3" are the evaluation item "prohibited area" (design standard number 8, conclusion data is 1 equipment drawer space"), the evaluation item "minimum (Design standard number 22)
The conclusion data is 300 nu+ from the wall), the evaluation item "straight pipe length" (the conclusion data for design standard number 42 is that the pressure regulating valve V-03 is 3D on the downstream side), etc.

In the sixth step 13, a function is called to check whether the evaluation conditions set in the fifth step 12 are satisfied for each layout evaluation point of the object to be evaluated, and the evaluation is executed. An example of the processing procedure in the sixth step 13 is shown in FIG.

First, a set of names of layout evaluation points of the evaluation object is retrieved from the intermediate data storage section 5c. In this example, as shown in FIG. 9 (A-12, S-1, EL-1, .
6, N21-BOO3-1) (7) The set is taken out. Next, one evaluation point is selected from the set of layout evaluation points in order from the front according to the evaluation point counter. In the initial state of this embodiment, the evaluation point counter is 1, so the evaluation point "8-12" is selected. For example, when the evaluation counter is 7, the evaluation point rV-03J is selected. Next, the coordinates of the selected evaluation point are retrieved from the intermediate data storage section 5c and written into the image data storage device 3 via the image data output section 5e. After this process is completed, the image display device 2 reads the coordinates of the evaluation point written in the image data storage device 3 and when the evaluation point counter is 2, and
FIG. 20 shows an example of an image in which marks of evaluation points are displayed. The star mark in the middle part on the left side of the figure represents this mark, and is made blinking or brighter to distinguish it from other evaluation points. Further, the evaluation conditions of the evaluation object are retrieved from the intermediate data storage section 5c, and a function for checking each evaluation condition is retrieved from the processing procedure storage section 5b using the evaluation item of the evaluation condition data as a key. In this example, the check function "prohibited area" is used for the first evaluation condition, the check function "minimum interval" is used for the second evaluation condition, and the check function is used for the third evaluation condition. "Length of straight pipe length" etc. are extracted.

In the seventh step 14, the check functions read in the sixth step 13 are executed one by one to determine whether the evaluation point violates the design criteria (satisfies the evaluation condition). An example of the processing procedure at the seventh step 14 is shown in FIG. From the intermediate data storage section 5c,
Attribute data and layout data of the selected evaluation points,
Additionally, the layout data of all stored layout objects is retrieved. Next, based on these data, the evaluation condition check functions read in in the sixth step 13 are executed one by one for the selected evaluation points, and its success or failure is determined. At this time, if the evaluation is negative, a check flag "1" is written in the intermediate data storage section [5c].

After performing this process for all check functions, the next step is to determine whether the check flag is set. If the check flag is set (the design standard is violated), the process moves to the next eighth step 15, and if the check flag is not set (the design standard is not violated), The evaluation point counter is incremented by one, this value is written into the intermediate data storage section 5c, and the process returns to the sixth step 13 to carry out the evaluation of the next evaluation point.

An example of the check function is shown in FIG. 22, taking the check function "straight pipe length" as an example. First, the target name of the conclusion data of the evaluation condition is extracted and it is determined whether it is upstream or downstream. If it is upstream, take out the coordinate value in the incremental direction and elbow radius of the elbow point immediately before the selected evaluation point, and calculate the value of (coordinate value of evaluation point) - (coordinate value of elbow point) - (elbow radius). do. If it is downstream, extract the coordinate value in the incremental direction of the elbow point immediately after the selected evaluation point and the elbow radius, and (
Calculate the value of (coordinate value of elbow point) - (coordinate value of evaluation point) - (elbow radius). Next, the value of the conclusion data of the evaluation condition is extracted. Therefore, the previously calculated value and the retrieved value are compared to determine whether the calculated value is greater than or equal to the retrieved value. If it holds true, immediately move on to the execution of the evaluation condition of Shin (execution of the next check function); if it does not hold, set check flag 1", extract the number of the violated design standard from the evaluation condition data, and These are written into the intermediate data storage section 5c, and the next evaluation condition is executed.

In this embodiment, when the evaluation point counter is 7, that is, the evaluation point V
An example of executing the evaluation condition for number 3, that is, the check function "straight pipe length" when -03 is selected, will be described below. Evaluation point ■-03 is an intermediate device and its type is a pressure regulating valve, so the check function "straight pipe length" is executed. First, since the target of the conclusion data of the evaluation condition is "r downstream", the elbow point rEL immediately after it is determined from the layout data.
-3" is selected, and the coordinate value in the increment direction is "13550".
” and the elbow radius “800” are extracted.Also, since the coordinate value in the increment direction of the evaluation point ■-03 is 11750, the value of 13550-11750-800=1000 is calculated.Next, the conclusion data of the evaluation condition The value of 3r) = 3X
Since 400=1200 is extracted and 1000<1200, this check function does not hold. In other words, the evaluation result is negative. Therefore, check flag ``1''
'' is set, and the violated design standard number 42 is written into the intermediate data storage section 5C. In this embodiment, after executing the seventh step 14 when the evaluation point counter is 7, FIG. 23 shows an example of storing the checked check flag and the number of the violated design standard.

In the eighth step 15, when the check flag is set, the content of the violated design standard is displayed on the display device 1. An example of the processing procedure in the eighth step 15 is shown in FIG. First, the number of the violated design standard is retrieved from the intermediate data storage section 5c. Next, character display data and schematic diagram display data of the design standard including the design standard number are extracted from the intermediate data storage section 5C and written into the image data storage device 8 via the image data output section 5θ.

After executing the processing procedure of the eighth step 15, the image display device 2 reads the design standard character display data and schematic diagram display data written in the image data storage device 3, and displays an image on the display device 1 according to an embodiment of the image. is shown in FIG.

In the ninth step 16, an input is made as to whether or not the layout of the object to be evaluated is to be modified based on the violated design standard. An example of the processing procedure at the ninth step 16 is shown in FIG. Here, when modifying the layout, the input device 4 is used to specify the "line modification" item in the menu area. From here, the layout correction execution mode is entered and the process proceeds to the next tenth step 17. On the other hand, if the layout is not to be modified, the input device 4 is used to instruct the "Continue" item in the menu area. This will return to the layout evaluation execution mode again.

Next, the evaluation point counter is incremented by one and written into the intermediate data storage section 5c, and the process returns to the sixth step 13 again to evaluate the next evaluation point.

In the tenth step 17, based on the violated design standard,
Correct the layout of the evaluation object. 10th step 1
An example of the processing procedure in step 7 is shown in FIG. First, on the display screen of the evaluation object, the user uses the input device 4 to specify the elbow point to be modified, and moves, deletes, or adds a new elbow point.

In this process, the input device 4 is, for example, a two-dimensional coordinate input device such as a joystick or a mouse.

In the coordinate input device 4, an encoder that converts the displacement into coordinate values is connected to a mechanism that converts the movement of the operating part into displacement in two orthogonal directions on a plane.

Further, the coordinate input device 4 is connected to an input section 5o of the arithmetic processing device 5.
The coordinate values are written to the arithmetic processing unit 5 and an interrupt signal is transmitted via the arithmetic processing unit 5.

Until the coordinate input device 4 is operated and an interrupt code is sent to the arithmetic processing device 5 via the input section 5C, the indicated point is displayed on the screen of the display device 1 corresponding to the coordinate position indicated by the operating section. . Next, the new coordinates of the corrected elbow point are written into the intermediate data storage section 5c together with its name code. Furthermore, on the display screen of the evaluation object, the intermediate device to be modified is designated using the input unit W4 and moved.

Next, the new coordinates of the corrected intermediate device are written into the intermediate data storage section 5C together with its name code. In this example, the piping rHD-3J is installed in the passage space indicated by diagonal lines on the left side.
In order to bring the elbow points EL-2 and EL-3 closer together,
Operation on display device 1 when moving 0mm to the left (X direction) and further moving intermediate equipment point v-03 upward (-2 direction) by 1C200m+ to secure the straight pipe section on the downstream side An example of an image showing the state of
As shown in the figure.

Further, among the layout data of the evaluation object before modification stored in the intermediate data storage section 5c, the modified layout points (root points) are replaced with new coordinates and stored again.

FIG. 29 shows an example of the storage format of the layout data of the evaluation object after layout correction stored in the intermediate data storage unit 5c in this embodiment. Next, the coordinates of the corrected layout evaluation points are selected from the layout data and written into the image data storage device 3 via the image data output section 5e.

After this processing, the image display device 2 reads the coordinate data of each layout evaluation point after layout correction written in the image data storage device 3, and displays an example of an image for displaying each layout evaluation point on the display device 1. Shown in Figure 30. Finally, the evaluation point counter is returned to the corrected initial layout point number, and the process returns to the sixth step 13.
The evaluation continues again from the corrected first layout point.

Finally, in the eleventh step 18, the processing procedure explained above is repeated, and after the evaluation is completed for all layout points, the modified layout data is sent to the layout data storage again via the layout data output section 5f. The data is stored in the device 6 and the process ends. An example of the processing procedure at the eleventh step 18 is shown in FIG. The number of evaluation point counters is taken out from the intermediate data storage section 5c, and it is determined whether it is larger than the total number of layout points. If it is not large, the process returns to the sixth step 13 and repeats the processing procedure starting from the layout evaluation. If it is larger, it means that the evaluation has been completed for all layout points, so the corrected layout data is stored again in the layout data storage device 6 via the layout data output unit 5f, and all processing is completed. .

It goes without saying that a plurality of display function parts may be arranged side by side depending on the layout to be displayed, evaluation conditions, and complexity of the schematic diagram.

〔Effect of the invention〕

According to the present invention, since the layout evaluation function part is automated, the time required for checking the validity of the layout and whether the design standards have been complied with, that is, the comprehensive review, can be significantly reduced, and oversight of design standards can be avoided. It is also possible to eliminate design errors caused by

In addition, the evaluation is performed for each layout point, and if any design standards are violated, the contents are simultaneously displayed on the display screen, so the designer can immediately visually see which design standards are being violated at which evaluation points. This eliminates the possibility of overlooking design standards, and allows for partial correction of layouts on the spot interactively, greatly improving the efficiency and speed of layout planning. Furthermore, since the revised layout is re-evaluated to ensure that the design standards are reflected, reliability is increased.
