Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manifold block design support device for three-dimensionally designing a portion of a manifold block in a hydraulic circuit diagram, and more particularly to a method for arranging parts of the manifold block design support device prior to piping design. ..

[0002]

2. Description of the Related Art Conventionally, the design work of a manifold block used for hydraulic equipment is performed by drawing a six-sided drawing corresponding to the manifold block at a full scale or a half scale on graph paper.
In addition, all the parts to be placed are cut into paper and the designer
We will proceed with the piping work while arranging the pattern of the parts, assuming a pattern that will be arranged well on the floor plan.

Then, when the piping state for the manifold block can be roughly seen, a manufacturing drawing is drawn to check whether there is any interference between the actual piping and parts or whether the design rules are satisfied. If you find a problem, you'll either have to fix it, or in some cases, try again.

[0004]

However, in the design work of such a conventional manifold block, it is extremely difficult to change the arrangement of parts, piping, size of the block, etc. There is a problem that it takes a lot of effort. In other words, the designer keeps his concentration for a long time while gazing at the drawing and proceeding with the design in his mind. Therefore, when designing a block having a large number of parts and a high density of piping, it may take about one week.

Also, due to oversight, there are many cases in which there is interference in the layout and piping among those that have once been designed, and those that do not satisfy the design criteria. The present invention has been made in view of such conventional problems, and incorporates design work into a computer to provide various functions according to the flow of the design work, and particularly to a block surface to be performed at the beginning of the design work. It is an object of the present invention to provide a method for arranging parts of a manifold block design support device, which can appropriately arrange parts in the device.

[0006]

FIG. 1 illustrates the principle of the present invention. First, the present invention is a display means 1 for displaying a five-view or three-view of a manifold block on a CRT screen 6.
And a component arranging means 2 for arranging components on the five-view or three-view, and when a connection point between the plurality of arranged hydraulic components is designated, piping between the plurality of hydraulic components is performed by the shortest path search process. A manifold block design support device provided with an automatic piping means 3 to be connected.

In the present invention as a method of arranging the parts of such a manifold block design support device, in the parts display frame 7 in which a plurality of hydraulic parts obtained from the hydraulic circuit diagram are provided in a part of the CRT screen 6. , And select an arbitrary part in the parts display frame 7 by the operator's operation, and after this selection, specify the arrangement position of the part on the block surface of either the 5th view or the 3rd view It is characterized in that the selected part is displayed and arranged at a position as a real figure having the same scale as the block.

In the component display frame 7, identifiable component graphics obtained by simplifying the actual component graphics are displayed as icon components. Further, as the designation of the placement position of the component with respect to either of the five-view or the three-view, it is also possible to specify by the two-dimensional coordinate dimension of the placement view other than the clicking operation of the cursor.

Further, by designating the correspondence relationship with the already placed parts, the already placed parts and the newly selected parts can be arranged in a straight line. Further, the already-arranged parts can be moved by selecting the already-arranged parts and designating another position. On the other hand, for a part having an embedded portion in a state of being arranged in a block, the corresponding figure of the embedded portion is displayed on another block drawing.

When a component placement position is specified not only on the surface of the block but also inside the block, the selected component can be displayed and placed in a state of being embedded inside the block.

[0011]

According to the manifold block design support apparatus of the present invention having such a configuration, the parts can be arranged freely on the CRT screen, and therefore it is most suitable for the piping work between the parts to be performed subsequently. Various parts can be easily arranged.
In addition, since the component once placed can be moved to another position, so-called temporary placement of the component can be performed, which is effective when a designer devises a concept.

Further, since the parts can be arranged also by designating the two-dimensional coordinate dimensions on the block surface, for example, the work for arranging the parts at the center of the block surface can be surely and easily performed. Furthermore, a plurality of parts can be arranged in a straight line by designating a correspondence relationship with the parts that have already been arranged, and alignment can be facilitated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 is a system configuration explanatory view showing the overall configuration of a manifold block support device of the present invention. Figure 2
In the figure, 10 is a design support device of the present invention, which is a CRT.
Computer main body 20 with display 6, keyboard 2
1 and a mouse 22.

An appropriate external storage device such as a hard disk, a floppy disk or a magnetic tape is used for the design support device 10 to input file 12 and output file 1.
6, 18 are provided. The input file 12 stores a netlist file in which a portion formed by manifold blocks in the hydraulic circuit diagram is one unit, that is, each manifold block. The netlist file consists of a parts list and a netlist.The parts list identifies the parts name and number of hydraulic parts to be mounted on the manifold block, and the netlist identifies the nets of the hydraulic circuits that connect the hydraulic parts. To be done.

On the other hand, the library file 14 is used as a support library for the design work of the manifold block in the design support apparatus 10, and is, for example, a parts database, a DRC (design rule check) table file, a plug table file, a color table. It consists of files, nameplate list files, etc. Information on hydraulic components used in the design support device 10 is stored in the component database. The DRC table file stores check rules used for various inspections when the manifold block is designed. The plug table file stores information about plugs when holes are formed from the end faces of the manifold block.
The color table file stores color data for assigning specific colors according to the design work of hydraulic parts, piping, and plugs.

Further, as the output files 16 and 18, a design file and a processed data file are obtained.
The output file 18 as a processing data file is used for machining the manifold block. On the other hand, the output file 16 as a design file is used as an input file when a design change is made using a manifold block that has already been designed.

In the system configuration of the design support apparatus 10 of the present invention as described above, the design support apparatus 10 displays a five-view or three-view of the manifold block on the CRT screen 6 as shown in FIG. Means and input file 1
2 based on the operator's operation, the plurality of parts obtained from the parts list included in the netlist file
Between the plurality of hydraulic components by the shortest path search process when the connection point between the component arranging means 2 arranged on the plan or the three plan and the plurality of hydraulic components arranged on the five or the three plan is designated. The function as the automatic piping means 3 for connecting the pipes is provided.

In addition to this, in the present embodiment, a completion inspection means for performing a completion inspection each time the automatic piping is completed, and further, after the completion of all the pipe connections, the suitability of the block size is judged and the block size is determined as necessary. A function as a block reducing means for reducing is also added. FIG. 3 is a flowchart showing a manifold block design process by the design support device 10 of FIG.

First, when the code number of the manifold block to be designed is designated by activating the design support device 10 of the present invention, the process proceeds to step S1, where the hydraulic component placement processing is performed, and if the component placement is completed in step S1. For example, the process proceeds to the next step S2, and the automatic piping process for each net is executed.
In the automatic piping of each net, when the operator commands the automatic piping by designating the ports of a plurality of hydraulic components, the shortest path search process is three-dimensionally executed to generate the automatic piping result.

Next, in step S3, the operator determines whether or not there is a part or net to be moved in the state where the automatic piping is completed, and if there is a part or net to be moved, the moving process is performed in step S4. In this movement process, move the cursor to the net or part that is the target of movement and specify it as the movement target, and then move the cursor to the position you want to move and click to move the part or net while maintaining the overall piping connection relationship. Can be moved.

Then, in step S5, it is checked whether or not there is a part or net to be deleted, and if there is, a step S6.
To delete. This deletion process may be performed by pointing the cursor to the component or net to be deleted and executing the deletion command. Subsequently, at the stage where the design process for the specific net is completed, the process proceeds to step S7, and a pipe completion inspection is performed. This piping completion inspection automatically determines whether or not the current design state satisfies the design specifications of the manifold block given as the input file.

Then, in step S8, it is checked whether or not the piping of all the nets is completed. If the piping is not completed, the process returns to step S1 and the same operation is repeated from the next component arrangement, or the process returns to step S2. Repeat the process from the automatic piping of the next net. When the completion of piping of all nets is determined in step S8, the process proceeds to step S9, and it is determined whether the block size in the current design state is appropriate. In the design support apparatus of the present invention, since the manifold block is displayed with a dimensional allowance on the initial screen, the block size becomes large when the piping of all nets is completed.

Therefore, in step S10, block reduction processing is performed. The block reduction processing can be realized by designating the block size reduced in the horizontal and vertical directions on the screen. Further, instead of designating the block size, the block size can be reduced by pushing the block end face in the direction perpendicular to the surface. Furthermore, it goes without saying that changing the block size can not only reduce the size but also increase the block size. In such block size reduction (including expansion), the block size can be reduced while maintaining the connection relationship between the hydraulic components.

When the block reduction processing is completed in step S10, it is checked in step S11 whether or not it is necessary to move or delete the part or net, and if it is necessary, the process returns to step S3 to move and / or delete. Process.
If it is not necessary to move or delete the part or net, the process returns to step S9 again to judge whether the block size obtained by the block reduction is appropriate or not, and if it is the optimum size, the series of design processes is ended.
