1 is a block diagram of a system for providing attribute-based building information modeling (BIM) information according to an embodiment of the present invention.

Referring to FIG. 1, the web-based BIM information providing system 10 includes a client 20 and a BIM server 30. The client 20 and the BIM server 30 may transmit or receive information through a wired internet network or a wireless internet network.

The client 20, which may be implemented as a computer, for example, a PC, a notebook, or a mobile communication device, may request property information on a target building desired by the user from the BIM server 30 via the Internet network, and may request the BIM server 30 from the client. Program that can receive and process information, such as display or render, by receiving the extracted and processed information.

The client 20 may transmit the attribute information of the target building desired by the user to the BIM server 30 through the web or the Internet network (S10).

The attribute information may include at least one of information about a building object or attribute information of the building object.

For example, the building object may mean a wall, a window, a window, a roof, a staircase, a space, or the like that constitutes a building. In addition, the property may include a function, structure, or use of the building object, and may mean an object style or an object property according to an embodiment.

The BIM server 30 extracts information corresponding to the attribute information from the BIM (building information modeling) information for the target building stored in the database 36, and extracts the extracted extraction information from the client 20 through a web or Internet network. (S20). The BIM server 30, for example, the database 36, despite its name, may have a plurality of two-dimensional drawing files, information corresponding to the plurality of two-dimensional drawing files, a plurality of three-dimensional drawing files, or the plurality of Information corresponding to a three-dimensional drawing file can be stored. According to an embodiment, the database 36 may store any information, a file, or data in addition to the drawing files.

Here, the BIM information may be processing information of an IFC (Industrial Foundation Classes) file (according to a standard) in an Extensible Markup Language (XML) format.

The BIM server 30 includes a control module 32, a query generator 34, and a database 36.

The control module 32 controls the overall operation of the BIM server 30 and receives property information on the target building transmitted from the client 20, analyzes the received property information, and queries according to the analysis result. The operation of the generator 34 can be controlled. In addition, the control module 32 may process the extraction information output from the database 36 and corresponding to the attribute information, and transmit the processed extraction information to the client 20. The control module 32 may include at least one servlet capable of performing the method according to an embodiment of the present invention.

2 shows an example of information executed in a client.

The operation of the attribute-based BIM information providing system 10 according to the present embodiment will be described with reference to FIGS. 1 and 2 as follows.

The user selects one target building from which a plurality of buildings included in the building list 21 displayed through the display device of the client 20 wants to know the attribute information, for example, BD # 2. The user inputs attribute information of the target building to obtain desired attribute information of the selected target building. According to an embodiment, the attribute information may be input to the client 20 through a template or user definition. For example, it is assumed that the target building BD # 2 is a 20-story building, and the attribute information is a 'floor plan of a specific room on the third floor, for example, 301' of the target building BD # 2.

The client 20 generates a script including information on the selected target building and selected property information. The script may be written in XML format, but is not limited thereto. That is, a program stored in the client 20 may generate the script.

The client 20 transmits attribute information on the target building, for example, a script in XML format to the BIM server 30 through the Internet network (S10).

The control module 32 of the BIM server 30, for example a servlet of the control module 32, sends a script in XML format to the query generator 34.

The query generator 34 converts the script in XML format into a database query statement and transmits the converted database query statement to the database 36.

Although FIG. 1 illustrates a query generator 34 separated from the control module 32, the query generator 34 may be implemented as part of the control module 32 according to an embodiment.

The control module 32 may be implemented as software capable of performing a function capable of processing attribute-based BIM information or hardware in which the software is installed, such as a processor.

The database 36 stores BIM information for each building included in the building list 21. The BIM information for each building may be processed or created in XML format, but is not limited thereto.

The database 36 corresponds to a portion of the BIM information for the target building among the plurality of BIM information (eg, BIM information for the buildings included in the building list 21), that is, attribute information in response to the database query statement. Only the information is extracted and the extraction information is transmitted to the control module 32. That is, the control module 32 may extract only information corresponding to attribute information desired by the user from the BIM information stored in the database 36 and transmit the extraction information to the client 20 in XML format.

Accordingly, the client 20 may display only a floor plan of a specific room, for example, 301 of a target building, for example, a 20-story building BD # 2, as shown in FIG. 2 according to the extraction information transmitted from the BIM server 30. Can render.

Accordingly, the BIM server 30 according to the embodiment of the present invention is an IFC file (or a file created according to the IFC standard, a file having an ifc extension) for the entire target building, for example, a 20-story building (BD # 2). Instead of transmitting itself as a file, only the information corresponding to the attribute information of the target building, for example, the floor plan of 301, may be transmitted to the client 20 via the Internet network. Therefore, since the BIM server 30 transmits only the extraction information corresponding to the attribute information to the client 20, the BIM server 30 may transmit the extraction information to the client 20 at a high transmission speed. In addition, since the client 20 does not need to render information on the entire target building, only the extracted information may be quickly rendered. Therefore, the user can quickly inquire only the attribute information.

According to an embodiment, the client 20 may request the BIM server 30 to transmit extraction information corresponding to the attribute information of the target building to another computer. Accordingly, the BIM server 30 may transmit the extraction information to the other computer according to the request.

3 shows another example of information provided from a BIM server to a client.

1 and 3, when a user wants to obtain three-dimensional information about a specific room of a specific floor of a specific building, the user may use a plurality of buildings included in the building list 21 through the client 20. Select a specific building, for example, a 15-story building as the target building (BD # 1), and three-dimensional information about the specific room (for example, room 3) of the 'specific floor (for example, 14th floor) of the target building. 'Can be entered as attribute information.

The client 20 generates a script in XML format that includes information about the target building (e.g., DB # 1) and attribute information (e.g., three-dimensional information for the 14th floor room 3), and in XML format. The generated script is transmitted to the BIM server 30 through the Internet network (S10).

The control module 32 of the BIM server 30 sends a script in XML format to the query generator 34. The query generator 34 converts the script in XML format into a database query statement and transmits the converted database query statement to the database 36.

The database 36 extracts only the information corresponding to the attribute information of the target building selected by the user from the BIM information for each building, and transmits the extraction information to the control module 32. The control module 32 processes or converts the extracted information into an XML format and transmits the extracted information to the client 20.

According to the extraction information transmitted from the BIM server 30, the client 20 may display or render only the three-dimensional information of the specific room of the specific floor of the specific building, that is, the property information desired by the user, as shown in FIG. have.

Accordingly, the client 20 of the property-based BIM information providing system 10 may receive only the extraction information corresponding to the property information of the target building desired by the user without receiving the information on the entire target building. Therefore, the client 20 may not only render extraction information about the target building quickly but also may quickly look up the attribute information.

4 shows another example of information provided from a BIM server to a client.

4 is similar to FIG. 3, the client 20 may quickly receive or display only extraction information of a specific room of a specific floor of a specific building from the BIM server 30.

5 shows another example of information provided from a BIM server to a client.

5 shows the material and structure of the floor and walls of a particular room of a particular floor of a particular building. For example, the user may input not only information on a specific room of a specific floor of a specific building, but also 'specific portions (eg, floors and walls)' of the measurement room as attribute information of the target building.

Therefore, when the client 20 generates a script including information on the target building and property information and transmits the generated script to the BIM server 30 (S10), the BIM server 30 interprets the received script. In operation S20, information corresponding to the analysis result may be extracted from the database 36, and the extraction information may be transmitted to the client 20. Thus, the user can view the attribute information displayed through the client 20.

6 shows another example of information provided from the BIM server to the client.

Referring to FIGS. 1 and 6, a case in which the user acquires only information on the annual area of the target building (eg, BD # n) will be described below.

The user inputs attribute information of 'year area' of the target building DB # n to the client 20. The client 20 transmits a script to the BIM server 30 that includes attribute information (eg, an open area) of the target building.

The control module 32 reads the area of each floor from the database 36 sequentially or all at once from the database 36 according to the received script, and sums the areas of each floor to open the area. Is calculated and the calculation result is sent to the client 20 as extraction information. Accordingly, the client 20 displays the extraction information corresponding to the attribute information, that is, the annual area of the target building DB # n.

Similarly, referring to FIGS. 1 and 6, a process of requesting 'number of A-type doors on the second floor' of the target building (eg, BD # n) as attribute information will be briefly described as follows.

The user selects the target building DB # n from the building list 21 and inputs the number of A-type doors on the second floor of the selected target building DB # n to the client 20 as attribute information. . The client 20 generates a script including the number of A-type doors on the second floor of the target building DB # 2 as the attribute information and transmits the generated script to the BIM server 30.

The control module 32 interprets or decodes the received script to extract the number of A-type doors on the second floor of the target building DB # 2 from the database 36 and extract the extraction result (eg, DA2). To the client 20. Thus, the client 20 can display the number of A-type doors on the second floor of the target building DB # n.

According to an embodiment of the present disclosure, the user may request the BIM server 30 as shape information, shape information, electrical design information, fire design information, or air conditioning design information of the target building to check extraction information corresponding to the property information.

According to another embodiment of the present invention, the information providing method may extract specific information from information stored in a file unit (for example, a file having an extension of dwg, doc, ppt, or xls) and provide the extracted information to the client. For example, when the client 20 requests the server to extract and transmit only information on a specific page or only information of a specific drawing (eg, FIGS. 1 to 10) from one file stored in the database 36, The server may transmit only the information of the specific page or the information of the specific drawing to the client 20.

The attribute-based BIM information providing method according to an embodiment of the present invention can be embodied as computer readable codes on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, hard disk, floppy disk, optical data storage, and the like, and also in the form of carrier waves (eg, transmission over the Internet). It also includes implementations. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. And functional programs, codes and code segments for implementing the present invention can be easily inferred by programmers in the art to which the present invention belongs.
