Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic circuit diagram creating apparatus and control method known as CAD for creating a hydraulic circuit diagram using a computer.

[0002]

2. Description of the Related Art In recent years, a CAD system has been introduced in the field of hydraulic circuit diagram design, in which a computer is used to carry out design and drawing work. For example, Japanese Patent Laid-Open No. 61-18468.
No. 6 is known. In creating a hydraulic circuit diagram by such a CAD system, hydraulic components used in the circuit diagram are prepared as component data, necessary components are selected and arranged on the CRT display, and the circuit is arranged after the components are arranged. I am trying to make a connection.

[0003]

By the way, the data of the hydraulic circuit diagram created in the CAD system is usually printed out as a circuit diagram and used in a manufacturing process or the like. However, a part of the hydraulic circuit is used as a manifold block. In the case of manufacturing, it is necessary to further design a manifold block manufacturing drawing.

In the design work of a conventional manifold block used for hydraulic equipment, a six-sided drawing corresponding to the manifold block is drawn on a graph paper at the original size or 1/2 scale, and all the arranged parts are printed on the graph paper. We are proceeding with the piping work while cutting and arranging the pattern paper of the parts, assuming a pattern that the designer will arrange well on the 6th view.

However, in such a conventional manifold block designing work, it is extremely difficult to change the arrangement of parts, piping, size of the block, etc. Therefore, it takes a lot of effort to design on a desk. There is a problem, and when designing a block having a large number of parts and a high density of piping, it may take about one week. Therefore, the inventors of the present application have proposed a manifold block design support device that captures the design work of a manifold block into a computer and provides various functions according to the flow of the design work to support the function.

In such a manifold block design support device, the circuit data of the hydraulic circuit diagram of the manifold block and the data of the parts list arranged in the manifold block must be prepared as an input file.
Here, when the hydraulic circuit diagram is created by the conventional CAD system, the circuit data and the parts list of the manifold block cannot be created individually. Therefore, the designer of the manifold block can check the CAD system creation drawing while looking at the drawing. There is a problem that the circuit data and the parts list of the manifold block area need to be created again as file data, which complicates the processing and that the circuit diagram data created by the CAD system cannot be effectively used.

The present invention has been made in view of the above-mentioned conventional problems, and is a hydraulic pressure capable of directly supplying a part of the circuit diagram and the parts list as input file data to a manifold block design support device using a computer. An object is to provide a circuit diagram creation device. It is another object of the present invention to provide a control method of a hydraulic circuit diagram creation device that facilitates setting change of attributes when setting attributes required for command execution by a layer structure.

[0008]

FIG. 1 illustrates the principle of the present invention. The present invention is a hydraulic circuit diagram creation device that creates a hydraulic circuit diagram using a computer device. When a specific circuit area of the created hydraulic circuit diagram is designated, a parts list of circuit parts existing in the designated area is displayed. It is characterized in that a parts table creating means is provided for generating and outputting together with the circuit diagram data.

The parts table creating means creates a parts table by designating an area to be realized as a manifold block in the created hydraulic circuit diagram. Further, when the circuit diagram data created in the past is read and a design change such as addition, correction, or deletion is made, the parts table creation means automatically corrects the parts table read simultaneously with the design change.

On the other hand, according to the present invention as a control method of a hydraulic circuit diagram creating apparatus for creating a hydraulic circuit diagram by using a computer device, in the present invention, when data processing is executed by an arbitrary command, it is necessary for the data processing. In addition to providing a layer for setting attributes, a sub-layer is provided that allows you to change some of the attributes of this layer.When a command is executed, the attributes of the corresponding layer are set in the command, and this layer It is characterized in that whether or not it belongs to a layer is determined, and if it belongs to a sublayer, the attribute held by the sublayer is set in a command to change the attribute set by the sublayer.

[0011]

According to the hydraulic circuit diagram creation apparatus of the present invention having such a configuration, when a manifold block area is designated on the hydraulic circuit diagram created on the CRT screen, the circuit data is targeted to this manifold area. A parts table can be created and obtained as an output file, and by providing this output file as an input file to a CAD system that designs the manifold block, the design process of the manifold block using the created data of the present invention as it is can be performed. Can be realized.

Regarding the design change, when past circuit data and the parts list are read and additions, corrections, and changes are made to the circuit diagram, the parts list is corrected according to the result of the design change, and the design change is made. It can be done efficiently. Furthermore, if you set the attribute of the process to be executed by a command with the concept of a layer and you want to execute a command by changing a part of the set attribute, conventionally you have to separately set a layer with a partly changed attribute. Although complicated, according to the present invention, it is possible to easily change some attributes of the layer to be changed by the sublayer.

When the manifold block area is designated, the connection status of the parts and nets in the area can be grasped, and the part / net data can be output as one manifold block in the final output process.

When the manifold block process is completed, the parts table process is performed in the next step S8. In this parts table processing, parts numbers are assigned to the parts placed on the hydraulic circuit diagram, and the outline frame shape of the parts table created in advance in the library mode is stored in the parts table library file stored in the library file in FIG. When the parts table is loaded and the parts table creation process is executed on the loaded outline of the parts table, the number of parts is counted and a parts table is automatically generated.

First, the parts table created by the processing of the present invention has the format configuration shown in FIG. 4 and is composed of an item part, a data part and a modifying part. The item part and the modifying part are created in advance in the library mode. .. The data part is generated by referring to the item part of the parts table library loaded in the circuit diagram input mode.

In step S4, the parts table created in the library mode is called. Then step S5
The part number is set to the part of the circuit diagram according to the rule determined in advance. When the setting of the part number is completed, the process proceeds to step S6, and the parts table is automatically generated according to the format of the parts table library loaded in step S4.

When the automatic generation of the parts table is completed, in step S7, a corresponding one is selected from a plurality of formats corresponding to one logical symbol and set in the parts table. Further, in step S8, as other settings, for example, names corresponding to parts,
Select and set the manufacturer. FIG. 6 shows step S in FIG.

In FIG. 6, first, in step S100, the parts having the part numbers set on the circuit diagram and the parts data are collected. Then, sorting is performed to rearrange the data collected in step S101 in order of part numbers. When the sorting is completed, the number of identical parts is counted based on the part number in step S102. Then step S
In step 103, the outline of the parts table having the designated number of lines is automatically generated based on the parts table library loaded in advance. After the automatic generation of the parts table, the part number, the number of parts, the manufacturer, etc. are set according to the format specified in step S4.

Next, a specific example of the circuit diagram creating process according to the present invention will be described with reference to the screen explanatory diagram of the CRT. FIG. 7 shows an initial screen when selecting and arranging parts in new creation in the drawing input mode. In this initial screen, a window 40 showing the outer shape of the selected component is shown on the left side of the screen. In this case, since "solenoid valve" is selected as the component group, the window 40 has, for example, 6 The type of solenoid valve is displayed. Therefore, the parts can be selected by moving the cursor 42 to the desired solenoid valve and clicking the mouse.

FIG. 8 is an explanatory view of the screen in a state where all the parts placement is completed. Here, the selection of components in the window 40 is performed by the arrow cursor, while the layout diagram in the circuit diagram is designated by the cross cursor 44. Further, in the window 40 of FIG. 8, symbols are displayed when the check valve is selected as the component group. FIG. 9 is an explanatory view of a screen in which a net connection is made to the placement parts shown in FIG. In this net connection, two cursors or connection points are net-connected by mouse-clicking the cursor 44 on the connection source port of the placement component and then mouse-clicking on the connection destination port or net.

FIG. 9 is an explanatory view of a screen in which a manifold block area is designated in the manifold block processing after the net connection processing is completed. That is, the cursor 4
The manifold block region 46 can be designated by surrounding the rectangular region of the circuit diagram realized by 4 as one manifold block with a one-dot chain line. FIG. 11 is an explanatory diagram of a screen when the parts table library is loaded. When you load the BOM library and point to any position with the mouse, the outline of the BOM is displayed at that position. In this parts table processing, as shown in the flowchart of FIG. 5, after calling the parts table library, the circuit diagram parts in the manifold block area 46
When the part number is set as shown in, the outer frame of the parts table having the part numbers 1 to 6 is automatically generated.

FIG. 12 is an explanatory view of a screen in which the part name "relief valve" is set to the first part having the part number 1 in FIG. 11 which is automatically generated. When setting this part name, a part name list 50 that can be used is displayed on the left side of the screen, so select the corresponding name "relief valve" from this part name list and move the cursor to the corresponding position in the parts table 48. By setting 44, the part name can be set in the parts table 48.

FIG. 13 is an explanatory view of the screen in which all the names have been set for the parts in the parts table 48, and then the model number "RV5-10-5-0-25" has been set in the next part model "MODEL NO" field. Is. Also in this component type setting, the component type code used to create the component table 48 is displayed on the left side of the screen, and the cursor 44 can be used to select and set it to a desired position. In setting the component type, the manufacturer, for example, is automatically set in the remark “REMARK” at the same time.

As described above, according to the present invention, the parts table is automatically generated for the manifold block area designated in the created circuit diagram and stored in the parts / net data file 28 together with the net data. It can be provided as input data for the manifold block design system. FIG. 14 is a flowchart showing a parts table process when a circuit diagram is created by changing the design of a hydraulic circuit diagram created in the past.

In FIG. 14, unnecessary parts are deleted or necessary parts are added to the circuit diagram created in the past which is input as a design change target. When the addition and deletion of the parts are completed, the part number is set to the added part in step S2, and the parts table is automatically corrected in step S3. That is, the added and deleted parts are checked, a new parts table is created for the added parts, and the deleted parts are deleted from the parts table. When the automatic correction of the parts table is completed, the format and other settings for the additional parts are made in step S4, and the series of parts table processing is ended.

FIG. 15 is a flow chart showing in detail the automatic correction process of the parts table shown in step S3 of FIG. 14 as a subroutine. In the parts table automatic correction process of FIG. 15, first, in step S100, the current parts table is compared with the parts to which the part numbers of the circuit diagram are attached to create an internal table for comparison. If the internal table for comparison can be created, the number of the same parts is counted in step S101, and the number of the same parts whose number has changed is corrected.

When the number of parts has been corrected, step S
In 102, the parts are added and / or deleted, and finally the row of the parts deleted in step S103 is deleted from the parts table, and the automatic correction process ends. As described above, in the creating process using the hydraulic circuit diagram created in the past, only the part in which both the circuit diagram and the parts table are changed is sufficient, so that the design drawing work can be efficiently performed.

Next, a control method for executing an arbitrary command in the hydraulic circuit diagram creating apparatus of the present invention will be described. In the present invention, the attributes required for command execution are set by the concept of layers. That is, when executing a certain command, first the pre-processing of the command is executed to set the attributes of the layer required for the command. The command will be executed according to the attributes set by the layer.

However, in the case of only the layer, if it is desired to change and use some attributes of the command,
It is necessary to newly set another layer with some attributes changed, which increases the number of layers and complicates processing. Therefore, in the present invention, in addition to the layer, the setting of various attributes of the layer is inherited as it is, and a sublayer capable of changing the setting of some attributes is introduced. By providing a sublayer for a layer in this manner, it is possible to easily change only the attribute to be changed by the sublayer without increasing the number of layers.

Command execution using the layers and sublayers of the present invention is as shown in the flowchart of FIG. In FIG. 16, if a command is given, first, in step S1, preprocessing corresponding to the command is performed. Then, in step S2, the attributes possessed by the layer necessary for this command are set. Then, in step S3, it is determined whether or not the data set by the layer attribute set belongs to the sublayer.

If it belongs to the sublayer, step S4
To set the sublayer attributes. This allows some attributes of the layer to be changed. Of course,
If it does not belong to the sublayer, the process of step S4 is not performed. Finally, in step S5, the command is executed according to the attribute of the layer or the set of the layer and the sublayer.

FIG. 17 is a flow chart showing an example of a specific command execution using the sublayer. A part of a plurality of character strings belonging to the normal parts in the parts table is set in the plotter. The case where it is set in the sublayer so that it is not output is taken as an example. In FIG. 17, first, in step S1, the external part of the component is output, and then in step S2, the character string part is output. The output of the character string portion in step S2 has the processing content of the subroutine shown in steps S100 to S104.

That is, in step S100, the presence or absence of the end of the character string is checked, and the flow advances to step S101 to set the character size, line width, etc. according to the layer attribute. Then, in step S102, it is checked whether or not the character string currently being processed belongs to the sublayer. If it belongs to the sublayer, the attribute of the sublayer is set in step S103.

In this case, the attributes of the sublayer are
Since the recording of the character string to the plotter is prohibited, output suppression is set. Then, in step S104, the plotter output to the character string is performed.
If the output suppression set of 103 is received, the character string is not printed by the plotter output, and only if the output suppression set of step S103 is not received, the character string is output to the plotter.

In the above embodiment, the case where the parts table is generated symmetrically with the manifold block creation area of the hydraulic circuit diagram has been taken as an example, but the specified area is limited to the manifold block. Instead, the parts list may be created by designating an appropriate circuit diagram portion as necessary.

[0053]

As described above, according to the present invention, a part of the hydraulic circuit diagram is designated and the parts table and the network data are collectively extracted in one output file. The input file of the block design system can be directly generated, and the computer design of the manifold block using the output data according to the present invention can be easily realized.

Further, regarding the design change of the hydraulic circuit diagram, the hydraulic circuit diagram and the parts table can be efficiently generated by reading the past circuit data and the parts table and making additions, corrections and changes. Furthermore, in addition to the concept of a layer that sets the attributes required for command execution, by providing a sublayer that changes some of the attributes set in the layer,
Highly flexible attribute setting is possible without increasing the number of layers.
