Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes a method of performing verification between a piping 2D drawing and a 3D model in a heterogeneous 2D piping system 10 and a 3D piping system 20. The 2D piping system 10 and the 3D piping system 20 are both computer-based systems. The 2D piping system 10 applies the SP P & ID and the 3D piping system 20 applies the AM (AVEVA Marine) But is not limited thereto.

Typically, the piping system of a ship comprises a group of equipment, pipelines, instrument lines, and the like. In the case of an equipment group, for example, a plurality of pumps, valves, etc. are provided as piping elements in the interior. However, as mentioned above, current 2D drawings and 3D models use different systems and systems developed by other companies. In this case, the information exchange between the systems is not smooth and the consistency between the two information is not ensured.

1 (a), in the conventional case, the worker directly compares and verifies the drawings 11 generated in the 2D piping system 10 and the drawings 11 generated in the 3D piping system 20 directly depending on the manual operation . 1B shows a state of processing data of the 2D piping system 10 by utilizing the schematic DB 15, the engineering DB 24, the modeling DB 25, and the like of the 3D piping system 20. The present invention is based on ISO 15926, taking into consideration data exchange and ship design characteristics, and a method for automatically processing important information exchange between two pieces of information.

Step (a) according to the present invention proceeds to a process of generating the standard neutral file 31 in the 2D piping system 10. The file conversion unit of the 2D piping system 10 converts the original CAD data into a predetermined standard neutral file 31. [ In FIG. 2, the file conversion unit illustrates a state included in the transmission processing unit 12.

As a detailed configuration of the present invention, in the step (a), the standard neutral file 31 is characterized by using the ISO 15926 xml file format. Using the ISO 15926 "Export Utility " provided by Intelligent P & ID, a 2D piping system 10, an ISO 15926 xml is generated as shown in FIG.

The step (b) according to the present invention proceeds to a process of generating the DB management table 32 by inputting the standard neutral file 31 to the 3D piping system 20. DB model creation and table creation for tool data management is a process of database customization. As shown in FIG. 4, a table is created by modifying data modeling in AM 2D to be suitable for the company in use.

In the detailed construction of the present invention, the step (b) is characterized in that the design characteristic of the engineering DB (24) is reflected in the input process of the standard neutral file (31). When the information is read by using the reception management unit 22 tool of the CAD information database, the information is converted by referring to the engineering DB 24 and reflecting the design characteristics thereof. For example, it reflects a change in the position of a valve (equipment) installed in the pipe or a position change for interference avoidance. The converted file can be created in a metafile format in which object information is stored in a list format.

The step (c) according to the present invention proceeds to a process of linking the 3D piping elements for each group by using the mapping table 33 in the 3D piping system 20. And utilizes the mapping table 33 provided by the AM of the 3D piping system 20 as shown in FIG. Attribute mapping is important in linking these piping elements.

In the detailed construction of the present invention, the step (c) is characterized by performing naming rules, term modification, and space processing between 2D pipeline 3D piping elements. In order to copy the standard neutral file 31 and construct it in the AM of the 3D piping system 20, it is required to convert it into 2D (for AM) through a predetermined modification. In this way, both 2D information and 3D information are contained in the AM. For example, the modification of the naming rule and terminology is a process of changing "abcd123" to "abcd134" and a space process to change "weight" to "wgt".

Referring to FIG. 5 (a), it is exemplified that an instruction is written in an attribute value (attribute value) in an equipment group to modify various attributes. In the case of the equipment group, a tag name of the standard neutral file 31 is basically used as a name, but in some cases, an item tag, which is a general attribute, may be used. Referring to FIG. 5 (b), it is exemplified that the modification is performed in the same manner as in FIG. 5 (a) in the pipeline group. A two-stage structure of "Piping Network System-Piping Network Segment" according to the 3D piping system 20 of ISO 15926 is used while the one-stage structure of "Pipe run" is used in the 2D piping system 10. That is, the "Pipe run" having the same item tag is bound to the "Piping Network System", and the individual "Pipe run" corresponds to the "Piping Network Segment".

In the detailed configuration of the present invention, the step (c) is characterized in that mapping is performed on an object-by-object basis having a unique piping element name and attribute information. In Fig. 6, the mapping between 2D and 3D in the 3D piping system 20 is performed on an object (part type name and attribute information) basis.

The step (d) according to the present invention proceeds to a step of verifying the connection state of the piping elements by using the DB verification viewer 35 in the 3D piping system 20. 6, the linkage information of the respective piping elements of the 2D and 3D data is generated through the comparison report 34, a separate 2D database is constructed from the converted information, and verification is performed through the DB verification viewer 35 as shown in FIG. .

Referring to FIG. 7, in the 2D piping diagram on the right side, the portion indicated by the selection mark is expressed in the 3D piping diagram on the left side in a manner such as color change, and the normal matching is verified. If an abnormal match is found, the process proceeds to the previous step to perform data update and conversion.

After the customization of the program and the database of the present invention is completed in this way, the interface between the 2D piping system 10 and the 3D piping system 20 is automatically performed from now on, It can guarantee a very high-speed operation. In addition, it is possible to ensure reliability and quality of work.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
