Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an equipment design support system, and more specifically, between equipment two-dimensional drawing data and equipment three-dimensional model data used for equipment design simulation in order to rationalize equipment design. It relates to a facility design support system with consistency.

[0002]

2. Description of the Related Art Conventionally, two-dimensional CAD systems (Computer Aided Design S) have been used for equipment design.
system), the design time is shortened and the drawing quality is improved.

Further, the two-dimensional drawing data created by the two-dimensional CAD system may be input as a three-dimensional model data into the robot simulation system for the purpose of preliminary evaluation of equipment design.

[0004]

When three-dimensional model data is created by the above robot simulation system, it is necessary to manage the consistency with the two-dimensional drawing data which is the basis of the three-dimensional model data. That is, if the content of the two-dimensional drawing data that is the basis for creating the three-dimensional model data is changed during the model input or after the model input, the three-dimensional model data is created with the changed content of the two-dimensional drawing data. I need to start over.

However, the individual equipment designer (robot simulation model creator) manages the consistency between the two-dimensional drawing data and the three-dimensional model data. Therefore, when the content of the two-dimensional drawing data is updated due to the design change by one equipment designer, the other equipment designer (robot simulation model creator) does not know that the update has been performed, and the simulation of the robot etc. is performed as it is. The harmful effect that it goes will occur. That is, when creating three-dimensional model data from two-dimensional drawing data by a plurality of equipment designers,
There is a problem that the consistency management between the two-dimensional drawing data and the three-dimensional model data becomes insufficient. Further, unless the facility designers are closely contacted with each other, the facility design will not proceed smoothly, and thus there is a problem that the work is not rational.

[0006] Therefore, the present invention has been made in view of the above, and manages consistency between two-dimensional drawing data and three-dimensional model data even when equipment is designed by a plurality of designers. It is an object of the present invention to provide a facility design support system that can perform a sufficient and rational facility design.

A structural feature is that the drawing data and the three-dimensional model data are further provided with a correlating means.

By thus associating the two-dimensional drawing data and the three-dimensional model data with each other, the centralized management of individual model data handled by another application (two-dimensional CAD system, facility object simulation system) can be easily performed. . For example, even when the content of the two-dimensional drawing data is changed, the three-dimensional model data related to the changed two-dimensional drawing data can be known. Here, if the creator data is registered in the three-dimensional model data, a notification regarding the content change may be issued to this person.

Further, in order to achieve the above-mentioned object, the equipment design support system of claim 5 is the equipment design support system (claims 1 to 4), wherein the monitoring means stores the two-dimensional drawing data. Change detection means for detecting the presence or absence of a change is provided, and when the update notification means has changed the two-dimensional drawing data, the change information is provided to the creator of the three-dimensional model data related to the two-dimensional drawing data. A structural feature is that a change notifying means for notifying the user is provided.

In this way, the simulation model creator involved in the two-dimensional drawing data relating to the change can be immediately notified of the change, so that the change can be dealt with early and the equipment can be designed smoothly. .

In order to achieve the above-mentioned object, the equipment design support system of claim 6 is the equipment design support system (claims 1 to 5), wherein the equipment target of the equipment target is simulated before the equipment target is simulated. The constitutional feature is that a pre-simulation change determination means for determining whether or not the two-dimensional drawing data has been changed is further provided.

That is, since it is possible to check whether or not the two-dimensional drawing data has been changed immediately before the simulation model is created, unnecessary work such as subsequent correction can be reduced, and the equipment can be designed smoothly.

In order to achieve the above-mentioned object, the equipment design support system of claim 7 is the equipment design support system (claims 1 to 6) in which the three-dimensional model is used during the simulation of the equipment object. It is a structural feature that an access control means during simulation for controlling access to the two-dimensional drawing data associated with the data is further provided.

That is, it is not preferable to change the two-dimensional drawing data carelessly during the simulation. Therefore, during this time, access to the two-dimensional drawing data related to the three-dimensional model data is suppressed. Therefore, useless simulation work can be suppressed, and equipment design work can be rationalized.
