Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a design support device and support method, and particularly to a distributed design support device and support that support multiple designers in jointly designing a design object. Regarding the method.

[Conventional technology]

The design process is normally carried out by multiple designers.

Below, a method for designing a laser beam printer connected to a personal computer or workstation will be explained, taking as an example a method in which multiple designers share the design. First, the overall designer decides on the overall size of the equipment and the layout of the main parts. After this, it is divided into the optical system section consisting of the laser emitting device and lenses, the drive system section consisting of the paper feed roller, motor, and gears, and the control system section consisting of the power supply device and electronic circuit board.Then, each section is specialized. Appoint a designer and proceed with the detailed design of the part in charge.

In the process of detailed design, each designer creates three original models on one drawing or a planning machine, and creates two dimensions of the shape.

We decide on materials, processing methods, and processing accuracy, and perform structural analysis programs and mechanism simulations.

Evaluate the validity of the design.

After the design is completed, preparations for manufacturing are made.The design department and the manufacturing department are usually separate departments, and the people in charge of design and the people preparing for manufacturing are different. In the manufacturing department,
Shapes from parts drawings and assembly drawings.

It reads dimensions, materials, processing methods, and processing accuracy, determines work procedures, and creates data necessary for production, such as programs for NC processing machines. Such work can also be considered part of design work in a broad sense.

When multiple designers work together to proceed with the design process,
Each designer works collaboratively with other designers to discuss areas of concern. In general, the negotiation part is
The attachment of parts by different designers refers to parts where the shape of one part cannot be determined unless the shape of the other part is determined, such as parts that are adjacent in shape or space. For this reason, if the shape of one of the connecting parts is changed, the shape of the other part must also be changed accordingly. In addition, between conceptual design and detailed design, between drawing creation and structural analysis, and between design department and manufacturing department, there is cooperation between them while consulting on design data such as shape, dimensions, and accuracy, just as in the above-mentioned areas of coordination. Proceed with the design.

The design of such interlocking parts cannot be determined solely by one designer; the consent of the relevant designers must be obtained. Therefore, when designing the interlocking parts, you use drawings that include not only the parts that you are responsible for, but also the shapes of the parts that other designers are responsible for. The design of the interlocking portion is performed, for example, as follows. It is assumed that a part a, which designer A is in charge of, has a structure that is bolted to a part, which designer B is in charge of. As a result of consideration by designer A, it is assumed that the position of the hole in the part must be changed to install part a. At this time, designer A first investigates the parts that will be affected by changing the hole position and obtains the parts list. Designer A shows Designer B, who is in charge of the design of Part A, the drawing of Part A with the hole position changed and changes the geometric data of Part A to match the new shape of Part A. It won't happen. In addition, it is necessary to write the graphic data of the new part modified by designer B in accordance with designer A's request into designer A's drawing and check whether the modified results are correct.

Conventional technology that supports collaborative design by multiple designers involves extracting and adding necessary data from a computer model created for a certain purpose. I was creating a model for a different purpose. For example, in the case of strength calculation, two-dimensional graphic data,
Dimensional data.

A part of the shape data is extracted from the part drawing consisting of accuracy data and annotation data, the shape is divided into nine divisions, the element division is performed, material data, restraint condition data, and load data are added, and the structure is created using the finite element method. I was creating a model for an analysis program. As another example, when creating a program for an NG machine tool, take out figure data, dimensional data, and accuracy data from the drawing data, add machine tool data and processing tool data, and create a cutting program for an NC lathe. I was creating it.

Another conventional technique is a method in which drawings of parts for which each designer is responsible are stored in two databases. When a certain designer changes a joint part, the contents of the change are communicated to the designers related to this part. When contacted, the designer retrieved the drawings containing the changed parts from the database.

Also, for example, G, Lang-Lendorff a
“Changes in
Understating of CAD/CAM:
a database-oriented appro
ach” (Computer-Aided Desi
gn Vol, 21 No, 5 June 1989
As shown in pp. 309-314), a creator group is assigned to each drawing, and this is used for data confidentiality management and protection. Specifically, only the creator of a certain drawing was allowed to make changes, or the created drawing was shown only to specific people and prohibited from being viewed by others.

[Problem to be solved by the invention]

The above conventional technology has the following problems.

(1) Designers should check whether the design data written in drawings and models represents the design data for the work they are responsible for.
It was unclear whether this was part of the work of another designer. Therefore, designers had to be aware of the purpose of the work they are currently doing and the differences in the people in charge, and when manipulating the data, they had to be careful not to change the design data that other designers were in charge of.

(2) Designers themselves had to remember which parts the design data of the parts they were designing conflicted with which designer's parts. Then, you must notify all related designers of the changes to your design data.

(3) After receiving the change notification, the designer may read out the design data of the changed part from the database again, modify the design data in his or her own drawings or models for the parts that the designer is responsible for, or There must be.

An object of the present invention is to provide a design support device that facilitates tasks that require cooperation, such as adjusting design proposals, among multiple designers when the design is divided among multiple designers.

[Means to solve the problem]

In order to achieve the above object, in the present invention, the design data constituting one drawing has information for specifying the purpose of the work.

In addition, we decided to provide means for determining the display form using information on the purpose of work added to the design data.

Additionally, a means was provided to transfer design data on one designer's drawings to another designer's drawings or models.

[Effect]

By adding information about the purpose of the work to the design data, it is possible to distinguish between the parts for which you are responsible for the design and the parts for which other designers are in charge.

In addition, by means of determining the display form using information on the purpose of work added to the design data, the user can see the scope of the current work he/she is responsible for by looking at the minus eye.

In addition, by adding information about the purpose of work to the design data, you can make changes to the design of the parts you are responsible for.
When modifying design data, it is possible to specify the design work for the part from the design data of the part that must be changed at the same time.

In addition, by means of transferring design data on one designer's drawing to another designer's drawing, it is possible to transfer the modified design data from the work purpose data added to the figure to the person in charge of the design of the specified work. can. This allows you to accurately convey the proposed design change to the other party. thus,
This makes it easier for multiple designers to collaborate and design drawings.

〔Example〕

An example of the present invention is shown below.

FIG. 1 shows an example of the configuration of an apparatus for realizing the present invention. The database ICl- stores part or all of the design data consisting of graphic data and attribute data of the design object. The control device 102 is a computer that reads and writes design data stored in the database 101 to and from a terminal device 104 connected to the network 103. terminal bag f
i104 is.

For example, a display device 105 such as a CRT or a flat display;
Keyboard 106 and mouse 10 for receiving and receiving commands from the user
7 etc. input bag T, CPU 108 serving as an arithmetic unit. It consists of a local memory 112 that stores design data during design. The CPU 108 is a data editing program 109
．． Database input/output program 110. It has an inter-terminal data input/output program 111. The data editing program 109 edits figure data and attribute data on the local memory according to user commands input using the keyboard 106 and mouse 107, and records the results in a CR.
Display on T 105. The database input/output program 110 gives read/# write instructions to the control device 102 via the network 103 in response to user instructions input from the keyboard 106 or mouse 107. Then, the design data from the database 1011 is read out and written into the local memory 112, and the design data from the local memory 112 is read out and written into the database 101. The inter-terminal data input/output program 111 transfers design data on the local memory 112a of one terminal, for example 104a, to the local memory 112b of another terminal, for example 104b, in response to a user's command.

If the terminal 104b is powered off, the terminal-to-terminal data input/output program 111 (1)
04a that the destination terminal 104b is powered off.

(2) When the terminal 104b is powered on, notify the user of the terminal 104a of this fact.

(3) You can choose to automatically transfer design data when the power is turned on to the terminal bag, etc.

Next, a method for implementing each program will be explained using the Nl drawing shown in FIG. 2 as design data.

In FIG. 2, 201 is for the designer, 202 is for the designer, respectively.
is the responsibility of designer B, and 203 is the responsibility of designer C.

The design data on the database 101 is, for example, as shown in FIG.
Represented by a data structure like . The common identification information 1d301 is identification information id for uniquely identifying design data on the database 101.

Since the drawing 201 of this embodiment is composed of only straight lines, the coordinate values 302 of the starting point and ending point are graphic data.

However, by expanding the data structure, it is also possible to handle arcs, three-dimensional curved surfaces, and solid models. Further, the design data is not limited to graphic data, but also includes attribute data necessary for design/production such as dimension data, matching relationships between surfaces and lines, and finishing symbols for surfaces. In this example, in order to indicate the name of the person in charge of designing the part represented by the graphic element as attribute data, an owner item 303 is added, which is a user name that can delete one graphic element and change the attribute value. . Further, the design data on the local memory 112 of each terminal 104 is expressed, for example, in the data structure shown in Section 3b. Local identification information 1d304 here
is for identifying design data on the local memory, and is unique for each terminal 104.

FIG. 4 shows the processing flow of the database input/output program 110. FIG. 4a shows the flow of processing for transferring data from the database 101 to the local memory 112. First, a command to open a database is sent to the control device 1102 via the network 103 (401).

Until all data on the database is read (40
2) Read design data on the database 403
), repeat writing to the local memory (404), close the database after reading all the data (405), write the data on the local memory to C
Display on RT (406) In this way, a copy of the design data on the database is created on the local memory and the design data is displayed on the CRT. In the process 403 of reading data on the database, by specifying a search condition, it becomes possible to read only a specified part of the design data out of the data on the database 101 into the local memory 112.

In this example, the search conditions include a method of specifying data to extract only specific design data, a method of specifying a range of coordinate values of graphic data to extract only a specific part on a drawing, and a method of specifying a range of coordinate values of figure data to extract only a specific part on a drawing. There is a method of specifying the owner to take out the share of the owner.

Display processing 406 can be realized by a processing flow as shown in FIG. Until all the data on the local memory is displayed (501), the data on the local memory is read out (502), the owner attribute of the design data is compared with the user name of the user using the terminal (503), and if they match, e.g. Set the line type attribute of the display format to solid line 504), and if they do not match, set it to dotted line attribute 505), and display it on the CRT (506).
).

In this way, when the display attributes are determined by comparing the attributes of the design data and the attributes of the terminal user, the part you are in charge of is displayed as a solid line and the part of other designers is displayed as a dotted line, as shown in Figure 6. Ru. Therefore, on each terminal, it is possible to distinguish at a glance between the design data for the part that the designer is in charge of and the part that other designers are responsible for. FIG. 6a shows the CRT screen of the terminal being used by designer A, and FIGS. 6 and 6C show the CRT screens of the terminals of designers B and C. In this example, different line types were used as display formats, but in addition to this,
Methods for changing the color, brightness, and line width on a color CRT, and for enabling or disabling mouse selection, are also described in steps 504 and 50 in the display processing flow of FIG.
This can be achieved by changing 5.

Next, the flow of processing for writing data on the local memory 112 of the database input/output program 110 into the database 101 is shown in FIG.

First, a command is sent to the control device 102 through the network 103 to open the database (407), and then until all data on the local memory is read out (408), the data is read out (409), and its owner attributes and It is compared with the user name of the terminal (410), and if it matches, it is written to the database (411); if it does not match, this data is in charge of another designer, so it is not written to the database, and the next data is read. Close the database after reading all data 412)
Finish the process. In this way, local memory 11
Database 1 contains only the design data that you are responsible for above 2.
The process of writing to 01 can be realized.

Next, the processing flow of the terminal-to-terminal data input/output program 111 is shown in FIG. The terminal-to-terminal data input/output program reads data from the local memory 112 on the network 1.
Program to send to other terminals through 03 (Figure 7a)
), and the process of receiving data sent from another terminal via the network 103 and writing it into the local memory 112 (FIG. 7b). The data input/output program may be activated by a user's command, or by a data transmission/reception command from another terminal.

For example, consider a case where data of a design change of a part in charge of a certain designer is transferred to a related designer. The designer at the transfer source issues a command to the data transmission program and starts it. Further, the reception program is activated by a command from the transfer source terminal and receives data. It is also possible to provide data transmission programs for each terminal, such as in a design progress management system that will be described later.

The processing flow of the transmission program is shown in FIG. 7a.

First, determine the data destination 701), secure a line on the network (702), and local memory 112.
Until all the above data is read out (703), the design data is read out (704), the owner name of the data is compared with the unused user name (705), and if they match, the data is transmitted through the network to the destination. It is transmitted to the receiving program of the terminal (706). After reading all the design data, the line used for transmission is opened (707), and the process ends. In the processing of this embodiment, the determination as to whether or not to send data is made in step 705 by comparing the name of the owner of the data and the user name of the person who has not yet used the data. This judgment process 70
By changing 5, for example, it is possible to add processing for determining graphic elements that are included in the area designated by the user, and to transmit only elements inside the area or only elements outside the area. Additionally, a flag indicating whether the graphic element has been changed after being sent is added to the graphic data. Then, a process for setting a flag when an attribute is changed or a new graphic element is defined is added to the graphic editing program. Send only design data with this flag set,
After transmission, by resetting the flag, it becomes possible to transmit only the design data that has been changed.

The data destination is determined as follows.

First, the graphic data that is affected by the change in the interlocking portion due to data manipulation is identified as follows.

(1) A method for the user to check graphic data.

(2) Constraint relationships such as dimensional relationships and surface/axis coincidence relationships are defined in advance, and after data manipulation (for example, movement of graphic elements), graphic data that no longer satisfies the constraint relationships is extracted.

(3) Use the interference check program to extract graphic data that interferes with the parts you are in charge of designing.

Next, the person in charge of design is identified from the owner column from the graphic data. It is possible to inquire about the designer group currently in use from each terminal through the network, and identify the terminal currently used by the designer extracted from the graphic data.0 When multiple graphic data are specified and the designers are different, Transfer the design data to the terminal that each designer is using.

Next, the processing flow of the receiving program is shown in FIG. First, a line on the network is secured (720), the design data is received (722) until the received data is finished (721), and it is checked whether the received design data is already on the local memory (723). in particular,
For example, the common ID is compared with the common ID of the design data on the local memory, and if there is matching data, it is determined that it already exists, and if there is no matching data, it is determined that it does not exist. If the design data already exists, the attribute data (in this example, coordinates and owner) of the design data on the local memory is rewritten with the attribute value of the received design data (7
25) If the same data does not exist, the received design data is added to the local memory (726), thus making it possible to replace the old design data with the newly sent design data. In another embodiment, process 723
By adding all the received data to the local memory without making any judgments, new design data and old design data can be displayed superimposed.

As described above, it becomes possible to exchange design data on local memory between arbitrary terminals.

This exchange program can be executed only when the user gives a command, or it can be executed every time a change is made by the data editing program.
It is also possible to exchange data automatically, and it is also possible to switch between the two.

An embodiment of the mechanical cutting support method according to the present invention is shown in FIG. The design data used as an example is shown in Figure 2,
Designers A, B, and C design each part independently. In FIG. 8, the left side is designer A's design procedure, and the right side is designer B's design procedure. First, each designer sends a command to the database input/output program to read design data on the database into the local memory of each designer's terminal (801).

The screen of designer A's terminal is shown in FIG. 6a, and the screen of designer B's terminal is shown in FIG. Designer A and designer B proceed with the design on their respective terminals, but in this example, designer A
As shown in FIG. 9a, it is assumed that the design data has been changed in a way that requires changes to the part that designer B is responsible for (802).

90'l is the part changed by designer A, and 902 is,
This is a part that designer B must change in response to changes made by designer A. Here, it is necessary to check whether the part that designer B is responsible for can be changed according to designer A's change proposal. Therefore, designer A gives commands to the terminal-to-terminal data input/output program and transfers the data on the local memory to designer B.
is transferred to the local memory of the terminal (803). Designer B starts a terminal-to-terminal data input/output program to receive and receive designer A's design proposal, and writes the sent design data to the local memory of his own terminal (804). At this time, the display screen of designer B's terminal displays the updated design data of designer A's portion 903, as shown in FIG. At this point, it is necessary to examine whether the change request by designer A is appropriate (805), and if there is a problem, ask designer A to correct it. If the design is acceptable, designer B refers to designer A's design proposal and changes the design data (806). The result is, for example, as shown in FIG. 9C. 904 is the changed part.

Then, by transferring the changed design data of designer B to the designer (807, 808), designer A
The output screen of the terminal is as shown in Figure 9d. Seeing this, Designer A confirms the changed design data (809)
. Designer A if you like.

MQH person B writes the design data on the local memory of each terminal into the database using the database input/output program (810). If there is a problem, create and replace the design plan again.

In this way, designers can freely exchange design proposals under consideration without going through a common database.

In this embodiment, each designer adds his or her name (or user identifier on the computer) as the owner's name to the graphic data and attribute data of the parts that each designer is in charge of designing. Therefore, editing of graphic data is limited to the owner to protect the data. Therefore, when designing the interlocking parts, it is necessary to ask other designers to make corrections according to your changes. However, when one designer has a lot of experience or when making small changes, he or she may want to manipulate the other designer's design data and tell them, ``I want you to fix it this way.''

This can be achieved by adding columns for the owner and operator to the design data, and by attaching data about the owner and operator and exchanging them between terminals. For example, if there is a conflict between a part a for designer A and a part for designer B, designer A modifies part a as well as parts a, and sends design data for both parts to designer B. At this time, the column for the person in charge of the design data of part a and the operator is set as designer A.

Also, the column for the person in charge of the design data for parts is Designer B.

The operator column is set to be designer A. Designer B has received the changed data of part a and the parts changed by designer A to match part a.

The data for the parts being created by Designer B and the data for the parts sent from Designer A have the same owner column, Designer B, but the operator columns are different, so they can be distinguished. be able to. Therefore, among the parts data assigned to designer B, the design data changed by designer A will not be confused with the design data originally created by designer B.

In addition, it may be necessary to change the person in charge of designing a component while transferring the design data. For example, assume that a part a for which designer A is in charge and a part a for designer B are connected via part C.

The design of such a part C is first done by a designer A as a part a.
It is efficient for designer B to design the interaction with the parts and then have designer B design the interaction with the parts. In order to realize such a function, it is sufficient to change the owner when exchanging data and then transfer the data. In other words, designer A is initially in charge of component C, and designer A designs the connecting part with component a. When the design is completed, the owner of the graphic data of part C is changed to designer B, and the data is sent to designer B's terminal. Designer B designs the connecting part between the parts and the part C. In this way, the design of parts can be carried out cooperatively and easily among the designers in charge.

Another embodiment of the invention is shown below. FIG. 10 shows a system for monitoring the work status of each designer, realized using an inter-terminal data input/output program. Database 1
Design data 1002 at the start of design is stored in 001. Multiple terminals 1004.1005, 1006.1007 are stored in the database via the network 1003.
is connected. 1004,1005゜1 of the terminals
0o6 is the terminal used by the designer and the database 100
They are editing the design data extracted from 1.

Designer A has added 1008, designer B has added 1009, and designer C has just added 1010. In this state, since it has not yet been determined, the added design data is not reflected in the design data 1002 on the database. On the other hand, 1007 is a terminal used by the manager of the design project. The administrator collects design data that each designer is considering in order to know the progress status of each designer. In this method, first, each designer's terminal 1004,
A command is given to the inter-terminal data input/output programs 1005 and 1006 through the network, and the data on the local memory of each terminal is transferred to the local memory of the administrator's terminal. When this is displayed, the data being considered by each designer is read and displayed as shown in 1007, so that the latest progress status of the designer can be grasped.

At this time, if any of the designers has turned off the power to the terminal, the data in the database 1001 can be read for that part. Further, even if all terminals are powered on, it is possible to read some or all data from the database 1001 based on instructions.

In the embodiments described above, information that identifies the designer has been used as an example of information that identifies the purpose of the work. The information specifying the work may be used as the information specifying the purpose of the work.

In other words, the two parts of the negotiation work are cost considerations and photographic performance considerations.

It is classified into performance study, reliability study, etc. Cost considerations include design, material, manufacturing, and transportation considerations.

It is classified as maintenance consideration, etc. In addition, design studies include optimization level studies, material studies include material studies, preform studies, purchasing sources, etc., manufacturing studies include processing method studies, assembly method studies, in-house production/outside production studies, etc., and transportation studies. is subcategorized into packaging considerations, etc. In addition, functional studies and performance studies are subdivided into form studies, size studies, two method studies, nine mechanism studies, two weight studies, etc. In addition, reliability studies are subdivided into usage history studies, 2 parts studies, 2 part composition studies, etc.

By dividing these study tasks at various levels and having the design data as information on the study tasks as information for specifying the purpose of the work, it becomes possible to design collaboratively while consulting on arrangements.

The effects of the embodiments of the present invention are as follows.

Since the design data includes information that specifies the purpose of the work, it is possible to distinguish between the part that the designer is responsible for designing and the part that is to be shared by another designer. Even if there is a complicated dispute between your part and another designer's part, you can only modify the part you are responsible for. Also, it is possible to prevent other designers from changing their assigned parts without permission.

Since the person in charge of designing the collaborative part can be easily identified, the person in charge of designing the collaborative part can be easily identified.

Since design data can be easily exchanged during the creation of the parts to be discussed, data can be collated between designers at any time during the creation, and design errors can be detected early.

In addition, since data can be easily exchanged during creation, coordination with other designers can be made during the trial and error process, broadening the scope of consideration of design proposals and improving the quality of the design.

〔Effect of the invention〕

According to the present invention, it is possible to facilitate tasks that require cooperation between designers, such as adjusting design plans.
