FIG. 1 shows a processing procedure used in the design support method of this embodiment. This processing procedure is stored in the processing procedure storage unit 5b, and is called and executed by the calculation unit 5a. This embodiment will be described below in accordance with the processing procedure of FIG.

First, step 12 searches for data of design appendages (here, target area, skeleton, small area, equipment, nozzle, etc.) based on the design target area designated by the input device 4, and this data is searched. Based on the above, the display device 1 displays the nozzle positions that are the start / end points (hereinafter, referred to as the start / end points of the design target) of the layout route of the design target area, the design attachment, and the design target. What is the design target area?
This is the area where the design object should be placed.

The detailed processing procedure of step 12 is shown in FIG. Processing procedure
At 23, necessary data is retrieved from the design appendage data storage device 6 based on the design target area input from the input device 4. That is, based on the design target area, the target area coordinate data is stored in the memory 6a of the design appendage data storage device 6, and the body coordinate data is stored in the memory 6c.
For small area coordinate data, memory 6d for equipment data, and memory 6e for nozzle data, and the retrieved data for each design accessory data input section.
Each is read into the intermediate data storage unit 5l via 5g. After execution of the processing procedure 23, the above-mentioned data stored in the intermediate data storage unit 5l in the processing procedure 24 is converted into image data and output to the image data storage unit 3 via the image data output unit 5f. The image display control device 2 reads the design appendage image data written in the image data storage unit 3 and displays it on the display device 1. This display image is shown in FIG. This display image is a plan view (two-dimensional) on the left side of the screen of the display device 1, and a perspective view (three-dimensional) on the right side. Further, in order to make the display easier to see, it is possible to display the target area, the skeleton, the small area, the device, and the nozzle in different colors. Next, when the design object has a branch, the branch name is designated by the input device 4 by the processing procedure 25, and the branch name is displayed at an arbitrary point designated by the input device 4. The processing procedure 25 is for performing the processing, and (1) the corresponding branch name is designated by the input device 4.

(2) The branch name is displayed at the point designated by the input device 4.

There are two procedures.

FIG. 13 shows the detailed procedure of the processing procedure (1) of processing procedure 25.
25A to 25C are shown. The branch name can be specified using the input device 4.
This is done by directly entering characters.

FIG. 14 shows processing procedures 27 to 31 which are detailed processing procedures of (2) of the processing procedure 25. In the processing steps 27 to 31, it is considered that the input device 4 is implemented by using, for example, a two-dimensional coordinate input device generally called a joystick or a mouse. The input device 4 is connected to a mechanism for displacing the movement of the operation portion into mutations in two directions orthogonal to each other on a plane, and an encoder for converting the mutations into coordinate values. Further, the input device 4 writes the coordinate values and transmits an interrupt signal to the arithmetic processing device 5 via the input unit 5e of the arithmetic processing device 5. In the processing procedure of (1) of processing procedure 25, the input device 4
Until the interrupt signal is transmitted to the arithmetic processing device 5 via the input unit 5e by operating the button, the designated point is displayed on the screen of the display device 1 corresponding to the coordinate position designated by the operating portion. This is the coordinate value x, written in the image data storage device 3,
The image display device 2 reads y, and the display device 1
Is executed by executing the processing procedure for displaying the designated point on the screen. By repeating the above process many times, any number of branch names are displayed and registered on the display screen. FIG. 15 shows an image displayed at an arbitrary position on the display device 1 by designating a branch name by the processing procedure 25.

Next, in step 13 of this embodiment, the display device 1
The start point and the end point of the layout design object are designated by the input device 4 based on the nozzle position and the branch name displayed on the, and the name and coordinates (in the case of branch, only the name) are stored in the intermediate data storage unit. Write to 5l. Step 13: (1) The coordinates on the screen are read by the input device 4.

(2) The nozzle name or branch name to be the start and end points of the design object near the position of the read coordinates and the position coordinates (not in the case of branch) of the design appendage data storage device 6
Read from.

It consists of two processing procedures.

FIG. 16 shows processing procedures 32 to 35 which are the processing procedures of (1) of step 13. These processing procedures 32-35 are the same as the processing procedures 27-30 of FIG.

FIG. 17 shows processing procedures 36 to 38 which are the processing procedure of (2) of step 13. In the processing procedure of (2) of step 13,
First, in step 12, the absolute coordinate data of the nozzles to be the start and end points of the design object (here, an example of piping) displayed on the display screen of the design attachment is displayed from the design attachment data storage device 6 as design attachment. The data is written into the intermediate data storage unit 5l via the product data input unit 5g (procedure 36). Next, coordinate conversion is performed, and the absolute coordinate system X, Y, Z is used to display the display coordinate system.
Convert to X, Y (whether in plan or perspective view),
The display position coordinates of the nozzle on the display screen are written in the intermediate data storage unit 5l (procedure 37). At this time, with respect to the branch name, the display position coordinates are already written in the intermediate data storage unit 5l by the processing procedures 27 to 31. Subsequently, the name of the nozzle or branch whose coordinate values x and y on the display screen written in the intermediate data storage unit 5l in the processing procedure 33 satisfy the following equation is selected.

X−e ≦ x ≦ X + e [1] Y−e ≦ y ≦ Y + e [2] Here, X is the value of the x coordinate of the display screen display position of the nozzle or the branch name, and Y is also the y coordinate of the y coordinate. It is a value. e is a predetermined value for selecting a neighborhood, and in this embodiment, it is assumed that e = 100.

For example, in the present embodiment, when the position on the display screen where x = 2550 and y = 980 is designated by the input device 4, the coordinate value of the designated position is input to the calculation unit 5a.
The calculation unit 5a selects a nozzle or a branch that satisfies the expressions [1] and [2] based on the input x and y coordinate values. That is, in the case of the above-mentioned coordinate values (x = 2550, y = 980), the nozzle N001 with X = 2500 Y = 1000 in the nozzle coordinate data shown in FIG. 10 is the nozzle of the formulas [1] and [2]. Nozzle N001 is selected because it meets the conditions. Therefore, the nozzle
N001 and its absolute coordinates (X, Y, Z) = (2500,2000,1000) are written in the intermediate data storage unit 5l (processing procedure 38). The nozzle name or branch name selected in the above processing procedure and its coordinate data (none in the case of branching) are temporarily stored in the intermediate data storage unit 5l. FIG. 18 shows how pointing points are displayed by the input device 4 and nearby nozzles or branch names are selected.

Next, in step 14 of the present embodiment, the specification data necessary for performing the layout design targeting the design object whose start and end points have been determined, and further, to determine whether or not the design criteria are satisfied. The required specification data is input by the external input device 9 according to a predetermined guidance and stored in the design object specification data storage device 7. FIG. 19 shows the processing procedure of step 14. First, in step 13, the names of design objects are determined in the order in which the start and end points are determined. According to the order, based on the name of the design object temporarily stored in the intermediate data storage device 5l, according to the predetermined guidance, the external input device 9 is used to input the specification data necessary for the layout design. Yes (procedure 39). FIG. 20 shows an example of the guidance system. According to this example, there are roughly two items. One is the specification of the design object itself, the other one
The first is an item for determining the specifications of the intermediate device provided in the design object. The branch information will be input in the latter case. Next, in the intermediate data storage device 5l, the name of the design target object, its start / end point names, and its position coordinates (none in the case of branching), which are temporarily stored, are manually entered and determined in the processing procedure 39. The specifications required for the layout design are written and stored in the design object specification data storage device 7 as a set (processing procedure 40). These process steps 39
And 40 are repeated until the determination of the processing procedure 41 becomes “Yes”. FIG. 21 shows an example in which the design object specification data storage device 7 is stored and stored in a square format by the above processing.

Next, in Step 15 of the present embodiment, the design criteria data storage device 10 is constructed and stored in advance, and the design criteria and rules written in the IF-THEN type as a constraint condition for the layout design, After counting all the numbers, the numbers are ordered from the written order, and only the numbers are surrounded by a grid, and all are displayed on the display device 1.

FIG. 22 shows the detailed processing steps 42 to 45 of step 15.
First, the design standards stored in advance in the design standard data storage device 10 are numbered according to the storage order and written in the intermediate data storage unit 5l of the maximum value (process procedure 42). Next, on the screen of the display device 1, vertical X lines,
The horizontal Y column is divided into X × Y = N, and each grid is numbered in the order of vertical → horizontal. The number and the corresponding position coordinate (Xmin, Xmax, Ymin, Ymax) of the grid are stored in the intermediate data storage unit. Write to 5l (procedure 43). Further, the grid position coordinate data is written from the intermediate data storage unit 5l to the image data storage device 3 via the image data output unit 5f (processing procedure 44). Of the numbers 1 to N stored in the intermediate data storage unit, all the numbers equal to or smaller than the maximum value of the design standard numbers (that is, the number of stored design standards) are used as image data via the image data output unit 5f. Write to the storage device 3 (procedure 45). The image display control device 2 reads the display image data from the image data storage device 3 and causes the display device 1 to display an image in which the grid and the design reference number are displayed in the corresponding grid.
Shown in Figure 23. In this example, it is shown that 89 pieces of design reference data are stored in the design reference data storage device 10.

Next, in step 16 of the present embodiment, the design standard number displayed on the screen in step 15 is input by the input device 4.
It is arbitrarily designated and selected, and is set as a constraint condition for automatically arranging the design object in the next step 17.

FIG. 24 shows the detailed processing steps 46 to 52 of step 16.
Fig. 25 shows an example of design criteria when piping is a design object. As a processing procedure, first, in step 15, a designated point is moved within a lattice of a design standard number to be selected among the design standard selection menus based on the design standard numbers displayed on the screen. The input device 4 reads the coordinates of the designated point on the display screen (procedure 46). This processing procedure 46 is the same as the processing procedures 32 to 35 in FIG. Next, the coordinates that were read and
By comparing the position coordinates (Xmin, Xmax, Ymin, Ymax) of each grid stored in the intermediate data storage unit 5l in the processing procedure 43 (FIG. 22), the grid including the position of the read coordinate is searched for, and at the same time. The number is stored in the intermediate data storage unit 5l. further,
Using this number as a key, it is sent to the design standard data storage device 10, the design standard data of the corresponding number is read via the design standard data input unit 5j, and written in the intermediate data storage unit 5l (processing procedure 47). Next, this is written into the image data storage device 3 via the image data output unit 5f. The above procedure is repeated as many times as the design standard desired. Then, process step 49
The image display device 2 reads the design reference data written in the image data storage device 3 and displays it on the display device 1 to confirm the design reference selected in step 1. If you make a mistake in the selection, this process will cancel.
FIG. 26 shows an example of a screen display on the display device 1 of the selected design standard. Design standards are sequentially displayed in the order in which they are designated and selected. After the processing procedure 49, the screen of the design standard selection menu is displayed again, and the numbers of the selected design standard and the numbers not selected are displayed in different colors. In addition, by considering the process procedures 46 to 50, by designating the design criteria that are not selected in reverse, it is possible to save the time and effort when selecting most of the design criteria.
It shall be performed before the processing step 46. Finally, the selected design reference data written in the intermediate data storage unit 5l is
The selected design standard data storage device 11 is written and stored.

Next, in step 17 of the present embodiment, the automatic placement design of the design object is performed based on the specification data instructed in step 14 and the design standard selected in step 16.

FIG. 27 shows the detailed processing steps 53 to 53 of the automatic placement of step 17.
Shows 60. In process step 53, the design accessory data (name,
(Coordinate, type) is read from the design attachment data storage device 6 via the design attachment data input unit 5g. Also, step 14
The specification data of the design target object, which is instructed and stored in step 2, is read from the design target object specification data storage device 7 via the design target object specification data input unit 5h. Next, in processing step 54, based on the data of the design appendix read in processing step 53, the target area space is a cell (like a rectangular box, the coordinate values are three-dimensional, Xmin , Xmax, Ymin, Ymax, Zmin, Zmax) and define their attributes (adjacent cells, what can be seen in each direction, coordinates, etc.). In process step 55, the design standard selected in step 16 is read from the selected design standard data storage device 11 via the selected design standard data input unit 5k,
It is defined in the attribute as a constraint condition of the design object. In process step 56, the shortest route search for the design object is performed while satisfying the constraint condition in units of cells divided in process step 54. As a method of the shortest route, there is a maize method or the like. Next, in processing procedure 57, the arrangement of intermediate devices (valves, strainers, etc.) including branches is determined on the route of the design object determined in processing procedure 56. In the processing procedure 58, a process of redistributing the cell including the route is performed along with the definition of the route of the design object determined by the above processing procedure as an obstacle. Further, the arrangement determination of two or more design objects is performed by repeating the processing steps 55 to 58, and after the arrangement of all the design objects is determined, the result is automatically arranged in the processing procedure 60. The result data is stored in the storage device 8. This processing procedure stored in the automatic placement processing procedure storage unit 5c is to be sequentially called from the arithmetic unit 5a and then executed.

Further, in step 18 of the present embodiment, the result data of the design object determined in step 17 is read from the automatic placement result data storage device 8 via the automatic placement result data input section 5i. This is written in the image data storage device 3 via the image data output unit 5f. An example of an image displayed on the display device 1 after execution of step 18 is shown in FIG.

Finally, in step 19 of the present embodiment, it is determined whether or not the existing design standard stored in the design standard data storage device 10 needs to be changed. If the change is necessary, step 20 is performed. , Design standard construction processing procedure storage unit 5d calls the processing procedure to modify or add an existing design standard,
After reduction, in step 21, they are stored again in the design standard data storage device 10 as a new design standard.

In the above processing procedure, steps 15 to 22 can be repeatedly executed many times, and it is possible to perform the simulation of the layout design of the design object with the design standard as one parameter. There is.

The example of FIG. 28 shows exactly the same design attachment data, design object specification data, etc., and FIG. 29 shows an example of a display image as a result of changing only selected design criteria.
