The first component 301Ba corresponds to the first component 301Aa of the in-house BIM model 300A. That is, the first component part 301Ba includes, for example, a hoisting machine, a car, a rail, and the like, and shows a three-dimensional shape of these hoisting machines, a car, a rail, and the like. The first component part 301Ba is created by converting the file format of the first configuration 101Aa from the first file format (file format having the extension ".rfa") to the second file format. The second file format is, for example, a file format having an extension of ".sat". By this conversion of the file format, the first component part 301Ba from which the attribute information 60 assigned to the first structure 101Aa is deleted can be obtained. That is, the attribute information is not given to the first component part 301Ba.

Is different from the second component part 301Ab. For example, as shown in FIG. 8, the corresponding part 301Bb does not include the bracket 302 included in the second constituent part 301Ab. The point that the shape of the corresponding part 301Bb is simplified with respect to the second constituent part 301Ab may be, for example, that the curved portion (R portion) of the member is changed to a right angle. Further, the corresponding part 301Bb does not include the confidential information even if the second component 301Ab corresponding to the corresponding part 301Bb has confidential information. That is, the attribute information of the corresponding part 301Bb is the same as the attribute information of the second component part 301Ab corresponding to the corresponding part 301Bb, or the amount of information is larger than the attribute information of the second component part 301Ab corresponding to the corresponding part 301Bb. Less is. Here, the part information for forming the corresponding part 301Bb and the part information for forming the second constituent part 301Ab are stored in association with each other in the part information database 206a.

The 2D part 301Bc shows the two-dimensional shape of the elevator. Specifically, the two-dimensional shapes of the first constituent part 301Ba and the corresponding part 301Bb in the bottom view are shown. 2D101Bc is represented, for example, in a third file format. The third file format has, for example, an extension of ".dwg". The 2D part 301Bc is created by converting the file format of the 2D part 301Ac of the in-house BIM model 300A from the first file format (the file format having the extension ".rfc") to the third file format. By this conversion of the file format, as shown in FIG. 9, the 2D part 301Bc from which the attribute information assigned to the 2D part 301Bc has been deleted can be obtained. That is, attribute information is not given to the 2D part 301Bc.

At this time, the elevator modeling unit 202b converts the file formats of the first component part 301Ba and the 2D part 301Bc into the first file format which is the file format of the corresponding 101Bb. That is, the file format of the external BIM model 300B is the first file format. Further, the elevator modeling unit 202b includes (integrates) attribute information in the external BIM model 300B. The attribute information is non-confidential information, for example, information to be notified to a customer. The information to be notified to the customer is, for example, the number of passengers set in the elevator, the model of the elevator, the elevator manufacturer, and the like. As shown in FIG. 10, the item 161 (information) of the attribute information 160 of the external BIM model 300B is less than the attribute information (see FIG. 6) of the internal BIM model 300A. This is because the attribute information 160 of the external BIM model 300B does not include confidential information.

Here, FIG. 11 shows a state in which the corresponding part 301Bb is displayed on the display unit 114 of the terminal device 100, and FIG. 12 shows the corresponding part 3101Bb of the external BIM model 3100B of the comparative example on the display unit 114 of the terminal device 100. Indicates the displayed state. The corresponding part 3101Bb of the comparative example is created by converting the in-house BIM model 300A (second component part 301Ab) into the fourth file format. By this conversion, the external BIM model 3100C (corresponding part 3101Bb) of the comparative example in which the attribute information attached to the internal BIM model 300A (second component part 301Ab) is deleted can be obtained. The fourth file format is, for example, a file format having an extension of ".ifc". As can be seen from FIGS. 11 and 12, the corresponding part 3101Bb of the comparative example has the display defective part 3300, but the corresponding part 301Bb of the present embodiment does not have the display defective part 3300.

Further, the elevator modeling unit 202b adds positional relationship information to the external BIM model 300B. The positional relationship information is information indicating the positional relationship between the reference position of the external BIM model 300B and the reference position of the BIM model of the building.

The creation condition transmission unit 102a is a creation condition transmission means for transmitting the creation conditions input by the user to the server device 200. As described above, the creation conditions are conditions that indicate the specifications of the elevator desired by the user and the specifications requested by the customer. That is, the user specifies the conditions for creating the BIM part 301 of the elevator that can be incorporated into the BIM model of the building by inputting the creation conditions using the input unit 118 or the like. The creation condition may be read from an external storage device in which the creation condition is stored in advance.

Further, the integrated modeling unit 102b is an integrated modeling means for creating an integrated BIM model in a state in which the external BIM model 300B of the elevator received from the server device 200 is incorporated into the BIM model of the building stored in the BIM model database 106a. Is. The integrated modeling unit 102b creates, for example, the following integrated BIM model.

FIG. 14 is an exemplary diagram showing a specific example of the integrated BIM model of the first embodiment. In the integrated BIM model 500 shown in FIG. 14, the external BIM part 301B as illustrated in FIG. 7 is incorporated in the building BIM model 400, and the elevator corresponding to the external BIM part 301B is installed. It shows a completed image (three-dimensional image) of a building with a built-in elevator.

The display control unit 102c of the terminal device 100 is a display control means for displaying the integrated BIM model 500 on the display unit 114. The display control unit 102c can display only one of the BIM model 400 of the building and the BIM part 301B for external use.

Next, the operation of the BIM system 1 of the first embodiment will be described. FIG. 15 is an exemplary flowchart showing a specific example of the processing executed in the BIM system 1 of the first embodiment.

As shown in FIG. 15, in the first embodiment, the terminal device 100 first transmits the BIM part creation conditions to the server device 200 (S1). Then, the server device 200 receives the creation condition transmitted by the terminal device 100 in S1 (S2).

The server device 200 uses the parts information stored in the parts information database 206a to create an in-house BIM model 300A including the BIM parts corresponding to the creation conditions received in S2 (S3), and is received in S2. An external BIM model 300B including BIM parts corresponding to the creation conditions is created (S4). Then, the server device 200 transmits the external BIM model 300B created in S4 to the terminal device 100 (S5).

The terminal device 100 receives the external BIM model transmitted by the server device 200 in S5 (S6). Then, the terminal device 100 incorporates the external BIM model received in S6 into the BIM model 400 of the building stored in the BIM model database 106a to create the integrated BIM model 500 (S7). Then, the terminal device 100 displays the integrated BIM model 500 created in S7 on the display unit 114.

Here, the above process can be repeated. That is, the above processing is performed every time the creation condition is changed. At this time, each time the information transmission unit 202c transmits the external BIM model 300B, the integrated modeling unit 102b transmits the external BIM model 300B included in the integrated BIM model 500 to the most recently transmitted external BIM model 300B. Replace.

Next, other functions of the BIM system 1 will be described with reference to FIGS. 16 and 17. FIG. 16 is an exemplary diagram showing a specific example of an external BIM model including the skeleton parts of the first embodiment. FIG. 17 is an explanatory diagram for explaining the data flow of the BIM system of the first embodiment.

As shown in FIG. 16, the elevator modeling unit 202b of the server device 200 can include a modified part 600 that is a part of the BIM model 400 of the building and is a modified part of the external BIM 300B. In FIG. 16, a modified part 600 of a beam part is shown as part of the BIM model 400 of a building. The beam part as the original data of the changed part 600 is created by the elevator modeling unit 202b based on the information input by the operation of the input unit by the operator, for example. Further, the changed part 600 is created by the elevator modeling unit 202b based on the information of the beam part changed by the operation of the input unit (not shown) by the operator, for example. That is, the elevator modeling unit 202b creates a part of the BIM model of the building. The elevator modeling unit 202b creates the entire BIM model 400 of the building when the information capable of creating the entire BIM model 400 of the building is input. That is, the elevator modeling unit 202b creates at least a part of the BIM model 400 of the building. The input unit includes, for example, a keyboard, a mouse, and the like. Further, in this case, the server device 200 shall include a display unit 214 (see FIG. 17) for displaying each part and a model.

Next, another example of the method of creating the BIM model 400 of the building performed by the elevator modeling unit 202b will be described. FIG. 17 is an explanatory diagram for explaining the data flow of the BIM system of the first embodiment.

In the example shown in FIG. 17, the creation information providing unit 102d as the creation information providing means of the terminal device 100 transmits the creation information for creating the skeleton parts of the BIM model 400 of the building to the database 700. .. The database 700 may be provided on one of the server device 200 and the terminal device 100, or may be provided on a device different from the server device 200 and the terminal device 100. At this time, the information that the information for creating the skeleton parts has been transmitted to the database 700 is transmitted from the terminal device 100 to the server device 200. When the server device 200 receives the above information, the elevator modeling unit 202b of the server device 200 creates the skeleton part 400a based on the skeleton part creation information stored in the database 700. That is, the creation information providing unit 102d of the terminal device 100 provides the server device 200 with the creation information for creating the skeleton parts of the BIM model 400 of the building via the database 700. Here, the skeleton part 400a stored in the database 700 is selected by the operator operating the input unit 118 in the terminal device 100. Then, the creation information providing unit 102d of the terminal device 100 obtains (extracts) the creation information of the selected skeleton part 400a from the BIM model database 106a. An example of information for creating the skeleton part 400a is shown in FIG.

Further, when the shape of the skeleton part once selected is changed, the creation information providing unit 102d provides the changed skeleton part creation information to the server device 200 via the database 700. At this time, the information that the information for creating the skeleton parts is newly transmitted to the database 700 is transmitted from the terminal device 100 to the server device 200. When the server device 200 receives the above information, the elevator modeling unit 202b of the server device 200 creates (updates) the skeleton part 400a based on the skeleton part creation information stored in the database 700. That is, each time the elevator modeling unit 202b is provided with the creation information by the creation information providing unit 102d, the elevator modeling unit 202b creates (updates) the model of the skeleton based on the creation information sent to the provision. The above process may be executed by an add-on tool incorporated in the BIM system 1.

As described above, in the BIM system 1 of the first embodiment, the elevator modeling unit 202b provides a plurality of in-house BIM parts (the first BIM parts) corresponding to the creation conditions transmitted from the terminal device 100. An in-house BIM model (first BIM model) of the included elevator is created using the parts information stored in the parts information database 206a (parts information storage means), and an external BIM corresponding to the in-house BIM parts is created. Create an external BIM (second BIM model) of the elevator corresponding to the internal BIM including the parts (the second BIM part). The integrated modeling unit 102b (integrated modeling means) is in a state in which the external BIM transmitted by the information transmission unit 202c (transmission means) is incorporated into the BIM model stored in the BIM model database 106a (BIM model storage means). Create an integrated BIM model. The display control unit 102c (display control means) causes the display unit 114 to display the integrated BIM model created by the integrated modeling unit 102b. A plurality of in-house BIM parts (first BIM parts) have a first component part having attribute information and being represented in the first file format, and a plurality of in-house BIM parts (first BIM parts) having color information and being represented in the first file format. Also includes a second component. The plurality of external BIM parts (second BIM parts) are the first component part in which the attribute information is deleted by converting the file format from the first file format to the second file format, and the first component part. Corresponding to the second component part, including the corresponding part including the color information and the shape is simplified with respect to the second component part and represented in the first file format, and represented in the first file format. ..

Therefore, according to the present embodiment, for example, even if the attribute information such as confidentiality is deleted, it is possible to suppress the occurrence of a display defect portion in the second component part (external BIM model). As a result, the customer can create a perspective having a three-dimensional shape or a two-dimensional shape. In addition, the customer can consider the design of the second component part. Further, by making the first file format the same as the file format of the BIM model stored in the BIM model database 106a (BIM model storage means), it is possible to make it easier for the customer to use the external BIM model.

Further, the plurality of external BIM parts include 2D parts showing the two-dimensional shape of the elevator. Therefore, the 2D parts can be displayed on the display unit 114 of the terminal device 100. This allows the customer to create a drawing.

In addition, the external BIM model includes positional relationship information indicating the positional relationship between the reference position of the external BIM model and the reference position of the BIM model of the building. Therefore, the terminal device 100 can grasp the positional relationship between the reference position of the BIM model for external use and the reference position of the BIM model of the building. Therefore, it is possible to prevent the terminal device 100 from shifting the relative position between the external BIM model and the BIM model of the building.

Further, the integrated modeling unit 102b incorporates the external BIM model transmitted by the information transmission unit 202c into the BIM model stored in the BIM model database 106a based on the positional relationship information. Therefore, the BIM model for external use and the BIM model of the building are automatically aligned. It is possible to prevent the terminal device 100 from shifting the relative position between the BIM model for external use and the BIM model of the building.

In addition, the external BIM model includes a modified part that is a part of the BIM model of the building and the part is modified. Therefore, the terminal device 100 can update a part of the BIM model of the building to the changed parts. As a result, the manufacturing machine maker can create the changed parts and reflect the changed parts in the BIM model of the customer's building. In addition, the elevator manufacturer can convey to the customer an image of the shape and size of the skeleton required for the building by using the changing parts.

Further, the integrated modeling unit 102b replaces the external BIM model included in the integrated BIM model with the most recently transmitted external BIM model every time the information transmission unit 202c transmits the external BIM model. Therefore, the integrated BIM can be kept up to date.

In addition, the elevator modeling unit 202b creates at least a part of the BIM model of the building. Therefore, in the server device, the positional relationship between the BIM model elevator of the building and the BIM model can be examined.

In addition, the terminal device 100 includes a creation information providing unit 102d (creation information providing means) that provides creation information for creating a building frame part in a BIM model of a building. The elevator modeling unit 202b creates the skeleton parts included in the BIM model of the building based on the creation information transmitted by the creation information providing unit 102d. Therefore, in the server device, the positional relationship between the BIM model elevator of the building and the BIM model can be examined. In addition, the designer of the manufacturer does not have to do the modeling work of the skeleton parts.

Further, the elevator modeling 202b creates a model of the skeleton based on the most recently sent creation information each time the creation information is transmitted by the creation information providing unit 102d. Therefore, the skeleton parts of the server device 200 can be updated.
