Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a design confirmation support device, and in particular, the present invention relates to a design confirmation support device, and in particular, the validity of the arrangement of design objects and the presence or absence of interference between objects. The present invention relates to a design confirmation support device suitable for confirming.

[Conventional technology]

Conventional CAD devices convert data of a design object into image data, display it on a display, and visually check the data to confirm the design of the design object. Also,
As described in Japanese Patent Application Laid-Open No. 59-17382, there was a device that displayed orthogonal lines with scales on one display screen and visually measured the distance between two points on one screen.

[Problem that the invention seeks to solve]

However, as plant configurations become increasingly complex,
Having to keep looking at the data, fine scales, etc. on the display causes considerable pain to the designer. In addition, delicate areas had to be confirmed by frequent use of the enlargement function, making the operation complicated.

The system is designed to interactively check the validity of the arrangement of design objects, and the presence or absence of interference between objects, people passing through the passage, and objects being carried in. A particular feature is that the device is configured to display the scene visible from the position of the comparison object (or the eyes in the case of a human being).

[Operation] In the present invention, it is possible to interactively check the validity of the design and the presence or absence of interference between objects by moving a comparison object such as a human being relatively within the design object. Design confirmation can be performed quickly and accurately because the scene visible to the human eye can be displayed.

〔Example〕

Next, the present invention will be explained in more detail with reference to the drawings.

4 is an input device, 5 is an arithmetic processing unit, and 6 is a design object data memory. Arithmetic processing bag! i! 5 further includes an arithmetic unit 5a, a program memory 5b, an input unit 5C1, an image data output unit 5d, an output unit 5e for outputting a scene within human visual field, a design target data input unit 5f, and an intermediate data memory 5g.

FIG. 2 shows an example of a processing procedure called from the program memory 5b and executed by the arithmetic unit 5a.

In step 7, display the design target data.

In accordance with the condition data, the condition data of the design object to be displayed (plant, building, area etc.), input section such as a keyboard! i! Next, in process step 14, data of the design object is read from the memory 6 via the design object data input section 5f according to the condition data of the design object inputted in process step 13. Processing procedure in figure 4? An example of condition data input to the furnace 213 is shown.

In step 8, data such as passages are input and set as condition data for an object such as a person to move within the design object using the input device 4 such as a keyboard or a mouse. FIG. 5 shows an example of step 8.

In the processing procedure 15 of step 8, the coordinates of one point in the passage are inputted from the input device 4. In processing step 16, processing step 15
The single point coordinates of the passage input in step 1 are stored in the intermediate data memory 5g via the input section 5c.

In processing step 17, a passage point coordinate data counter indicating the number of data of passage point coordinates is incremented by one. In processing step 18, a flag indicating whether or not to continue inputting path point coordinate data is input from the input device 4, and a determination is made by the calculation unit 5a via the input unit 5c.

If the process is to be continued, the process returns to step 16; if the process is not to be continued, the process moves to the next step. FIG. 6 shows an example of the passage point coordinate data input in step 8 and the passage point coordinate data counter.

In step 9, the input device i! is used to define the shape of a human being, etc. Input the shape data of the object from step 4. Step 9
In processing step 19, first, the input device W4 such as a keyboard
Input the object shape data (vertex coordinate data) from
Next, in process step 20, the shape data of the object input in process step 19 is stored in intermediate data memory 5g via input section 5c.

The shape data of the object stored in the processing step 20 can be defined by the coordinate system of the object, as shown in the example shown in FIG. This shape data can be developed into absolute coordinate data according to the display condition data set in step 11. An example of the shape of an object to be compared is shown in FIG. 8, and an example of the vertex coordinates of the object shape in the object coordinate system will be described below. Figure 8 is 8
It is a rectangular parallelepiped made up of points.

Point 1: X = 300.0 Y = 2100.0 Z = -150,0 Point 2: X = 300.0 Y = 2100.0 Z = 150.0 Point 3: X = 300.0 Y = 0.0 Z= 150.0 Point 4: X= 300.0 Y= 0.0 Z=-150,0 Point 5: X=-300,0 Y=2100.0 Z= 150.0 Point 6: X=-300 ,0 Y=2100.0 Z=-150,0 Point 7: X=-300,0 Y= 0.0 Z=-150,0 Point 8: , X=-300,0 Y= 0.0 Z= 150.0 In step 10, in order to set the display conditions (viewpoint, reference point data, etc.) for displaying the design object on the display 1, the path data imported in step 8 is read from the intermediate data memory 5g, Find the amount of movement of the viewpoint, reference point, and object coordinates. FIG. 9 shows an example of step 10.

First, in processing step 21, path data is taken into the calculation section 5a from the intermediate data memory 5g.In processing step 22, movement distance pitch data that determines how far to move in one step is imported from the intermediate data memory 5k. From the calculation unit 5a
In the processing step 23, the moving direction is calculated from one of the one passage coordinate data and the next passage coordinate data by the calculation unit 5.
Find with a.

The moving coordinate pitch is determined using the moving distance pitch data as a parameter. An example of the processing method M23 is shown below.

Assuming that the passage coordinate data is shown in Fig. 6, and focusing on the first and second points of the 1 passage coordinate and the moving distance pitch P of 100.0, the moving direction is X = 21650.
0-24250.0 ±-2600,0Y= 1700
．． 0-t7oo, o=o,.

Z = 59400.0 - 59400.0 = 0.0, that is, unit vector (xo + yo + zo) = (-1, Ot O, 0, 0
,0).

The moving coordinate pitch is calculated by multiplying the above vector by the moving distance pitch P and calculating the vector Cx d , y d , z d) = (-100,0
,0,0,0,0).

Next, in processing step 24, , processing step 2
Using the moving coordinate pitch determined in step 3, the viewpoint and reference point for displaying the surrounding information that is displayed when the object moves according to the coordinate values and path data are determined in the calculation unit 5a.6 For example, the same as described in processing procedure 23. Taking the data of 1 as an example,
If the first fish of the passage coordinates is the starting point, the coordinate value of the next object is Xz = 24250.0 + (-100,0) = 2
4150.0Y z= 1700.0+0.0 =
1700.0Zz=59400.0+0.0 =59
400.0, and the viewpoint and reference point defined above are: For example, if the distance between the viewpoint and the reference point is 500.0, and the viewpoint is 100.0 behind the object, the viewpoint is V X = 24250.0+ (-100,0) −
x OX 100.0=24250.0 VY=1700.0+ 0.0-yOXloo, 0
= 1700.0 V Z =59400.0+ 0.0- z OX
100.0=59400.0 The reference point is: RX = V X + x d xsoo, o = 237
50.0RY = VY + ydX500.0
= 1700.0RZ = V Z + z d X
500.0=59400.0.

In the above example, when the point coordinates of the object set in step 9 are expanded into absolute coordinates, the result is as follows.

Point 1: X = Xz+ 300.0=24450

150.0=59250.0 In step 11, coordinate transformation is performed based on the design object read in step 7 and the display conditions set in step 10, and the result is displayed on the display 1.

FIG. 10 shows an example of step 11. First, process step 2
In step 5, the design object data is sent from the intermediate data memory 5g to the calculation section 5a. In processing step 26, the coordinate transformation of the three-dimensional coordinate data is performed based on the display conditions determined in step 10, and then the coordinate transformation from the three-dimensional coordinate data to the screen coordinate system is performed.
In the primary processing procedure 27 of performing coordinate transformation into dimensional coordinates and writing the bound image data to the image data memory 3 via the image data output section 5d, in the image step 12, the arrangement is In the six examples for checking validity, presence of interference, etc., the comparison object 30 has the shape of a human, and in particular, in order to ensure so-called head clearance, the object 30 is held in a state where the hand is raised higher than the head. It is.

In this state, based on the calculation result, the design object and the person are moved relative to each other, for example, the pipe 3
Check to see if there is any interference, to see if people can pass under it without any problems. If interference occurs, the display changes to red, for example, to indicate that the design of the pipe 31 is inappropriate.

In step 13, a flag indicating whether or not to end the above steps is designated from the input box e4 of the keyboard, etc., and if not, the process returns to step 10.

In the explanation of the above embodiments, interference between people walking along a passageway and equipment has been described as an example, but it is also important to check whether a specified space is secured between equipment 2, for example between pipes and electrical equipment, or if the equipment is being repaired. It is possible to easily, quickly, and accurately check whether objects will collide with surrounding equipment when they are lifted by a hoist and transported into the plant, using the perspective of a working tool inside the actual plant.
