Then, the key generation unit 202a of the server device 200 generates a support key, and registers the support key generated in the management database 206b in association with a user account that identifies the building (trader). Thereby, the elevating maker side starts management of the elevator designed by the contractor using the support key.

  Then, the server device 200 notifies the terminal device 300 of the support key. As a result, the support key is displayed in the support key column. Further, the key request unit 302b of the terminal device 300 associates a support key with the BIM part of the elevator. Thereby, the BIM part of an elevator can be identified with a support key.

  The generated support key is used in the order of the design database 206c, the construction database 206d, the construction database 206f, and the maintenance database 206g as information for identifying the BIM parts of the elevator.

  The cut-out control unit 302c is cut-out control means for performing control to cut out the periphery of the BIM part of the elevator from the BIM model of the building when transmitting the BIM part of the elevator to the server device 200. By performing the cut-out control, the BIM parts transmitted to the server apparatus 200 include the BIM parts of the structures existing around the elevator. In the present embodiment, when the pressing of the building model provision button 702 is accepted in the screen example shown in FIG. 7, the cutout control unit 302c performs control for cutting out the BIM parts to be provided to the elevator manufacturer from the integrated BIM model. .

  The parts transmission unit 302d is a transmission unit that associates the support key common to the construction process with the BIM part of the elevator registered in the server apparatus 200 and transmits the same to the server apparatus 200. In addition, when the BIM parts around the elevator are cut out by the cutting control unit 302c, the parts transmission unit 302d transmits the cut-out surrounding BIM parts including the BIM parts of the elevator together with the support key. .

  FIG. 9 is a diagram exemplifying a concept until a BIM part is registered in the design database 206c of the present embodiment in the BIM system of the present embodiment. As shown in FIG. 9, the cutout control unit 302c detects the figure around the BIM part of the elevator associated with the support key “12345” in the integrated BIM model, and narrows down the information around the elevator. Above, the BIM part for providing to the server apparatus 200 is cut out. It should be noted that the range 900 to be cut out may be manually selected by the user as a range that can be disclosed to the elevator manufacturer, or the range necessary for the elevator manufacturer to cooperate in the design of the elevator is automatically selected. May be.

  Then, the parts transmitting unit 302d transmits the cut BIM parts including the BIM parts of the elevator to the server apparatus 200 in association with the support key.

  Then, the registration unit 202b of the server device 200 associates the cut-out surrounding BIM part received from the terminal device 300 with the support key for identifying the elevator BIM part included in the surrounding BIM part, It is registered in the design database 206c (the process management storage means for the phase corresponding to the BIM part).

  Then, the terminal device 100 on the elevator manufacturer side designs the BIM parts of the elevator with reference to the BIM model registered in the design database 206c in accordance with the design cooperation request from the building side. Since the design database 206c includes BIM parts of structures around the elevator, the BIM parts of the elevator can be designed in consideration of the surrounding situation.

  The parts acquisition unit 302e is an acquisition unit that acquires the BIM parts of the elevator corresponding to the phase of the building process performed by the terminal device 300 from the server device 200. For example, the parts acquisition unit 302e downloads (acquires) the elevator BIM parts distributed by the server device 200. As another example, the parts acquisition unit 302e acquires the BIM parts of the elevator that has been redesigned by the elevator manufacturer after being transmitted by the parts transmission unit 302d. In the present embodiment, when the push of the elevator model reflection button 703 is accepted in the screen example shown in FIG. 7, the parts acquisition unit 302e changes the design of the elevator BIM after the server device 200 changes the design to the elevator manufacturer. Get a part.

  The design request unit 302f transmits a request for the design study of the elevator to the terminal device 100 of the elevator manufacturer. In the present embodiment, when the pressing of the design review button 704 is accepted in the screen example illustrated in FIG. 7, the design request unit 302 f transmits information about the design input by the user to the terminal device 100 of the elevator manufacturer. To do. Accordingly, the terminal device 100 of the elevator manufacturer performs design cooperation based on the information related to the design for the BIM parts of the elevator registered in the design database 206c.

  The approval unit 302g receives a selection of an approval button indicating that the current (predetermined) process included in the construction process has been completed, and that the selection has been accepted, and a support key for identifying the approved BIM parts of the elevator , Is a reception means for transmitting to the server device 200. In the example of the screen shown in FIG. 7, when the selection of the model approval button 705 is received, the approval unit 302 g determines that the approval has been received, and transmits to the server apparatus 200 that the approval has been received and the support key. .

  When the information transmitting / receiving unit 202d of the server apparatus 200 receives information indicating that the approval has been received, the information transmitting / receiving unit 202d corresponds to the current phase, assuming that the approval unit 302g has approved the BIM parts of the elevator in the current phase. The process management storage means (for example, the design database 206c, the construction database 206d, the construction database 206f, or the maintenance database 206g) suppresses updating of the BIM parts of the elevator corresponding to the phase. Then, the process proceeds to the next phase.

  In FIG. 3, a terminal device 400 is a terminal device used by a contractor, and is used to generate a BIM model of a building according to the phase in the construction cooperation phase of the construction process. For example, the terminal device 400 transmits a request for construction cooperation to the terminal device 100. Furthermore, the terminal device 400 requests the server device 200 to register a BIM part including the elevator in the construction cooperation phase. Further, the terminal device 400 transmits a creation condition necessary for creating the BIM part corresponding to the construction cooperation phase, and the calculation result of the server device 200 including the BIM part created according to the creation condition is transmitted to the server device. It has a function of receiving from 200.

  The terminal device 400 includes a control unit 402, a communication control interface unit 404, a storage unit 406, and an input / output control interface unit 408. A control unit 402, a communication control interface unit 404, a storage unit 406, and an input / output control interface unit 408 included in the terminal device 400 are included in the control unit 302, the communication control interface unit 304, and the storage included in the terminal device 300 of this embodiment. Description of the same configuration as that of the unit 306 and the input / output control interface unit 308 is omitted. The storage unit 406 includes a BIM database 406a that holds an integrated BIM model of a building used by a contractor.

  The control unit 402 reads and executes the process management application 402a. The process management application 402a includes a key request unit 402b, a cutout control unit 402c, a parts transmission unit 402d, a parts acquisition unit 402e, a design request unit 402f, and an approval unit 402g in terms of functions. The key request unit 402b, the cutout control unit 402c, the parts transmission unit 402d, the parts acquisition unit 402e, the design request unit 402f, and the approval unit 402g are a key request unit 302b, a cutout control unit 302c, a parts transmission unit 302d, Compared to the parts acquisition unit 302e, the design request unit 302f, and the approval unit 302g, almost the same processing is performed except that the BIM parts to be processed differ depending on the phase of the building process.

  FIG. 10 is a diagram illustrating a flow of BIM parts used by a plurality of vendors in the BIM system of this embodiment. As shown in FIG. 10, a construction contractor on the construction side, a construction contractor on the construction side, and an owner of the building on the maintenance side use a common support key “12345” regardless of the difference in the construction process. Manage BIM parts.

  As shown in FIG. 10, since the granularity of the BIM parts of the elevator changes, the design database 206c, the construction database 206d, the construction database 206f, and the maintenance are stored as databases for storing the BIM parts of the elevator every time the phase transitions. The transition proceeds in the order of the database 206g. Each time the phase of the construction process shifts, the building (contractor) side, the construction (contractor) side, the maintenance side, and the contractor using the BIM parts of the elevator change. Along with this, the terminals with which the elevator manufacturer's server device 200 communicates are changed to the building-side terminal device 300, the construction-side terminal device 400, and the maintenance-side terminal device 1000. Even when the trader changes, the support key “12345” for identifying the BIM part of the elevator is used. In other words, it is necessary to pass the support key when the contractor changes when the phase transitions.

  Any method can be used to transfer the support key between the contractors (for example, from the contractor to the contractor). For example, when the construction work is taken over, only the support key can be transferred or the support key can be transferred. You may hand over not only the key but also the BIM model. In addition, the user account of the contractor is registered in the management database 206b in association with the support key when taking over. Thereby, the contractor can use the BIM parts of the elevator associated with the support key.

[Configuration of Terminal Device 100]
Returning to FIG. 3, the terminal device 100 is a terminal device used by an elevator maker, and is used to perform design cooperation and design cooperation in response to requests from the terminal devices 300 and 400 regardless of the phase of the construction process. It is done.

The communication control interface unit 104 is an interface connected to a communication device (not shown) such as an antenna or a router connected to a communication line, a telephone line, etc., and performs communication control with the in-house network 550 and the network 500. Has the function to perform. That is, the communication control interface unit 104 has a function of communicating data with the server device 200, the terminal devices 300, 400, and the like via a communication line.

  The storage unit 106 is a fixed disk device such as an HDD (Hard Disk Drive) or a storage unit such as an SSD (Solid State Drive), and stores various data.

  The control unit 102 includes an internal memory for storing a control program such as an OS (Operating System), a program that defines various processing procedures, and necessary data. And the control part 102 performs the information processing for performing various processes by these programs. The control unit 102 includes an information communication unit 102a and a display editing unit 102b in terms of functional concept by reading and executing an application (not shown).

  The information communication unit 102 a is a transmission / reception unit that transmits / receives BIM parts to / from the server device 200. In the present embodiment, when a support key and a phase are received from a terminal device 300 or 400 for a design cooperation or design review request for a BIM part, the BIM of the elevator specified by the support key and the phase is received from the server device 200. Receive parts. In addition, when the BIM parts of the structure around the elevator are stored in various databases serving as the process management storage means, the BIM parts of the structure around the elevator are also received.

  The display editing unit 102b displays the BIM part received by the information communication unit 102a, and serves as an editing unit that edits the BIM part of the elevator based on the BIM part. The display editing unit 102b can also display a process management screen.

  FIG. 11 is a diagram illustrating a process management screen displayed by the display editing unit 102b. As shown in FIG. 11, a support key field 1100 for identifying a BIM part of an elevator and an elevator model registration button 1101 are provided. The display editing unit 102b accepts selection of the elevator model registration button 1101 when editing of the elevator BIM parts by the user is completed. Using the selection as a trigger, the BIM part of the elevator that has been edited is transmitted to the server apparatus 200 together with a support key and a registration request to the database corresponding to the current phase. As a result, the BIM parts of the elevator that have been updated in accordance with the design cooperation and the design study are stored in the server device 200. Further, the information communication unit 102a notifies the terminal devices 300 and 400 that have used the edited BIM parts of the elevator, that the editing has been completed.

  In this embodiment, each device constituting the BIM system has the above-described configuration, and the BIM parts of the elevator are collectively managed from construction to maintenance by performing the above-described processing up to the last phase of the construction process. can do.

  Above, description of an example of a structure of the BIM system in this embodiment is finished.

[Process of BIM system in this embodiment]
Next, an example of processing of the BIM system in the embodiment configured as described above will be described in detail with reference to FIGS.

  First, with reference to FIG. 12, the support key and BIM part association processing executed by the BIM system in the embodiment will be described. FIG. 12 is a flowchart illustrating an example of processing related to the support key of the BIM system in the embodiment.

  As shown in FIG. 12, the control unit 302 of the terminal device 300 accesses the server device 200 using a browser or the like, and displays an elevator information provision page on the display unit 314 (SA-1). A general-purpose elevator BIM part is disclosed and provided on the elevator information provision page so that any user can use it.

  Next, the parts acquisition unit 302e of the control unit 302 of the terminal device 300 downloads (acquires) the BIM parts of the elevator from the server device 200 (SA-2).

  Then, the control unit 302 of the terminal device 300 incorporates the acquired BIM part into the integrated BIM model of the building stored in the BIM database 306a and edits the integrated BIM model (SA-3).

  The process management application 302a of the terminal device 300 displays the screen of the process management application corresponding to the BIM part of the elevator, incorporated in the integrated BIM model of the building, on the display unit 314 (SA-4). Instead of the process management application, a URL embedded in the BIM part of the elevator may be connected to a BIM model providing site for requesting the elevator manufacturer to issue a support key.

  As shown in FIG. 7, in the screen example of the process management application in the BIM part of the elevator after downloading, the support key column 700 is blank. This means that the BIM parts of the elevator are not managed by the elevator manufacturer. Therefore, when the user wants the elevator manufacturer to ask for the elevator estimate indicated by the BIM part, the validity of the plan, or the design cooperation, issue a support key to identify the elevator BIM part. It is necessary to request from the elevator manufacturer.

  The key request unit 302b of the control unit 302 of the terminal device 300 transmits a support key acquisition request to the server device 200 on the elevator manufacturer side when the selection of the ID acquisition button 701 is accepted on the screen of the process management application. (SA-5).

  Then, the information transmitting / receiving unit 202d of the server device 200 receives the support key acquisition request (SA-6). Then, the key generation unit 202a of the server device 200 generates a support key (SA-7). The registration unit 202b registers the generated support key in the management database 206a (SA-8). Thereby, management of BIM parts and the like by the support key in the server apparatus 200 is started.

  Thereafter, the information transmitting / receiving unit 202d transmits the support key to the terminal device 300 that has requested the support key (SA-9).

  Then, the key request unit 302b of the terminal device 300 receives the support key transmitted from the server device 200 (SA-10), and displays the received support key on the screen of the process management application detector (see FIG. SA-11).

  Further, the key request unit 302b associates the received support key with the BIM part of the elevator (SA-12). Thereafter, this process is terminated.

  In this embodiment, a support key is assigned to the BIM part of the elevator by performing the above-described processing.

  Next, with reference to FIG. 13, basic processing performed in each phase of the construction process executed by the BIM system in the embodiment will be described. FIG. 13 is a flowchart illustrating an example of basic processing performed in each phase of the construction process executed by the BIM system in the embodiment. In the example shown in FIG. 13, the screen of the process management application of the BIM part of the elevator is displayed on the display unit 314 of the terminal device 300.

  When the elevator manufacturer performs design cooperation, not only the BIM parts of the elevator but also the BIM parts of the structure around the elevator are required. Therefore, it is assumed that the elevator manufacturer requests the construction contractor to provide a building model. In such a case, the contractor needs to cut out the range including the structures around the elevator as the examination request information.

  In such a case, the process management application 302a accepts the selection of the building model providing button (SB-1). Thereafter, the cutout control unit 302c accepts selection of a range to be provided to the server device 200 centering on the BIM parts of the elevator (SB-2). Thereby, in addition to the elevator, the BIM parts of the structure around the elevator are selected. Any method can be used to acquire the BIM parts of the surrounding structure. For example, the location of the elevator is automatically detected from the BIM model of the structure using the project ID as a key and included in the selected range. It is conceivable to automatically acquire information on the surrounding BIM parts.

  Then, the parts transmitting unit 302d transmits the cut-out range of BIM parts together with the support key to the server apparatus 200 (SB-3).

  The information transmitting / receiving unit 202d of the server device 200 receives the BIM parts in the cut out range (SB-4). Then, the registration unit 202b stores the received BIM part together with a support key in process management storage means (for example, the design database 206c, the construction database 206d, the construction database 206f, or the maintenance database 206g) corresponding to the phase of the BIM part. Register (SB-5). The process management storage means of the server device 200 manages the update history of the registered BIM parts.

  Then, the information transmitting / receiving unit 202d of the server device 200 transmits the registered BIM parts in the cut out range together with the support key to the terminal device 100 (SB-6).

  The information communication unit 102a of the terminal device 100 on the elevator manufacturer side receives the BIM parts in the range together with the support key (SB-7). The display editing unit 102b uses the received BIM part to check the surroundings of the elevator and edits the BIM part of the elevator according to the design cooperation (SB-8). For the design cooperation to the elevator manufacturer side, any method such as notification by e-mail or flag management by the process management storage means may be used.

  Then, the display editing unit 102b completes the design, for example, by adding a construction or a steel member necessary for construction, and registers the model in the project folder.

  Thereafter, the information communication unit 102a transmits the BIM part of the elevator registered in the project folder to the server device 200 together with the support key (SB-9). At the time of the transmission, BIM transmission including the vicinity of the elevator may be used.

  And the information transmission / reception part 202d of the server apparatus 200 receives the BIM part of an elevator with a support key from the terminal device 100 (SB-10). Then, the registration unit 202b stores the received BIM part of the elevator together with a support key, along with a process management storage unit (for example, a design database 206c, a construction database 206d, a construction database 206f, or a maintenance database 206g) corresponding to the phase of the BIM part. (SB-11). Thereby, the process management storage means of the server apparatus 200 updates the update history of the BIM parts again.

  In addition, the information communication unit 102a of the terminal device 100 on the elevator manufacturer side transmits the completion of the update of the BIM parts to the terminal device 300 of the contractor by using the BIM parts registered in the project folder as a trigger ( SB-12).

  Then, the process management application 302a of the terminal device 300 of the contractor receives the notification that the update of the BIM parts is completed, and displays that the update is completed (SB-13). Thereby, the user of the terminal device 300 can recognize that the BIM parts of the elevator have been updated by the design cooperation of the elevator manufacturer.

  The contractor needs to update the integrated BIM model of the building using the BIM parts edited by the elevator manufacturer.

  Therefore, the process management application 302a of the terminal device 300 of the contractor accepts the selection of the elevator model reflection button from the screen of the process management application (SB-14). Thereby, the parts acquisition part 302e makes a transmission request for the BIM parts of the elevator together with the support key and the current phase to the server apparatus 200 (SB-15).

  The information transmitting / receiving unit 202d of the server device 200 receives the transmission request for the BIM parts of the elevator together with the support key and the current phase (SB-16). Then, the information transmission / reception unit 202d obtains the BIM parts of the elevator identified by the support key and the current phase from the process management storage means (for example, the design database 206c, the construction database 206d, the construction database 206f, or the maintenance database 206g). It reads and transmits the BIM part of the said elevator to the terminal device 300 (SB-17).

  And the parts acquisition part 302e of the terminal device 300 of a construction company receives the BIM part of an elevator (SB-18). Then, the control unit 402 incorporates the received BIM part of the elevator into the integrated BIM model and displays the integrated BIM model (SB-19). As a result, the integrated BIM model is updated to the elevator BIM parts designed by the elevator manufacturer. In this case, when there is a part that needs further correction, the highlighting light of the part may be performed. At that time, a coping comment or the like may be displayed.

  And the approval part 302g receives selection of a model approval button from the screen of a process management application (SB-20). And the approval part 302g notifies the server apparatus 200 that the said phase was completed with a support key and the present phase (SB-21). By selecting the model approval button, the order for the elevator is confirmed.

  The information transmitting / receiving unit 202d of the server device 200 receives the completion of the phase from the terminal device 300 together with the support key and the current phase (SB-22).

  Then, the process management storage means (for example, the design database 206c, the construction database 206d, the construction database 206f, or the maintenance database 206g) corresponding to the phase performs BIM parts update suppression control identified by the support key ( SB-23). At the same time, the elevator manufacturer automatically updates the BIM model of the elevator in the design cooperation phase managed by itself to the BIM model of the elevator in the construction cooperation phase.

The specifications of the BIM parts in the phase are determined by the above-described processing procedure. Thereby, it is possible to shift to the next phase of the construction process. When moving to the next phase, a contractor such as a contractor may be changed from the contractor. However, even if the supplier is changed, the support key for identifying the BIM part of the elevator is taken over.
Any method may be used as the handover method, and the data indicating the used support key list may be transferred, or the integrated BIM model may be transferred.

  Moreover, the server apparatus 200 gives the use authority of a support key to a contractor, when a contractor uses the BIM part of an elevator.

  First, with reference to FIG. 14, a process for generating a BIM part and associating a support key with the BIM part in the BIM system in the embodiment will be described. FIG. 14 is a flowchart illustrating an example of a BIM part generation process and a process of associating a BIM part and a support key in the BIM system according to the embodiment.

  As shown in FIG. 14, the control unit 402 of the contractor's terminal device 400 receives an input of a support key and a creation condition for generating a BIM part (SC-1). The creation condition includes at least information indicating the current phase of the construction process. The support key is the support key delivered from the contractor who worked in the previous phase.

  And the control part 402 of the terminal device 400 transmits a support key and creation conditions to the server apparatus 200 (SC-2).

  Then, the information transmitting / receiving unit 202d of the server device 200 receives the support key and the creation condition from the terminal device 400 (SC-3).

  And the elevator modeling part 202c of the server apparatus 200 produces the BIM part of the elevator corresponding to creation conditions using the part information memorize | stored in the parts information database 206a (step SC-4). For example, the elevator manufacturer automatically modified the BIM model of the elevator in the construction cooperation phase from the elevator BIM model in the design cooperation phase so that it matches the creation conditions, and the BIM part of the elevator It may be generated.

  Then, the registration unit 202b of the server device 200 includes process management storage means (for example, a design database 206c, a construction database 206d, a construction database 206f, or Register in the maintenance database 206g) (SC-5).

  And the information transmission / reception part 202d of the server apparatus 200 transmits a support key and the BIM part of an elevator to the terminal device 400 (SC-6).

  And the control part 402 of the terminal device 400 receives a support key and the BIM part of an elevator (SC-7).

  The control unit 402 of the terminal device 400 creates an integrated BIM model (SC-8). Then, the control unit 402 of the terminal device 400 associates the BIM part of the elevator with the support key, and then displays it in the integrated BIM model (SC-9).

  Further, the terminal device 400 of the contractor can display the same screen example as in FIG. 7 from the BIM parts of the elevator. In this case, the design cooperation of the BIM parts can be realized for the terminal device 100 of the elevator manufacturer by accepting the selection of the design review button. Further, the specifications determined by the design are updated in the construction database 206d of the server device 200.

  In addition, the contractor, like the contractor, needs to receive approval for the production specifications of the elevator. In the present embodiment, the acceptance receiving process is performed in the same processing procedure as that after SB-20 in FIG.

  In addition, the contractor, like the contractor, needs to receive approval for the production specifications of the elevator. In the present embodiment, the acceptance receiving process is performed in the same processing procedure as that after SB-20 in FIG. When the selection of the model approval button is accepted, the elevator manufacturer moves to the manufacturing phase.

  In other words, in the past, images were examined by system simulation and approval was obtained separately from drawings. However, it is possible to reduce the work of creating those books and to proceed with specification determination quickly.

  When the construction cooperation phase is completed, the update of the construction database 206d is suppressed. And the decision information of the BIM parts of the elevator for which construction approval has been obtained is stored in the decision database 206e. In the subsequent manufacturing phase, the elevator is manufactured based on the determination information in the determination database 206e.

  Then, after the manufacturing phase is completed, the process proceeds to a construction phase in which installation is performed. When the installation work is completed, the BIM system shifts to the maintenance phase.

  In the maintenance phase, the building management company manages the BIM model using the terminal device 1000. At that time, the server device 200 gives the use authority of the support key to the building management company. In the BIM system, the maintenance management menu is changed. The server apparatus 200 generates the elevator BIM parts necessary for maintenance. In addition, the server device 200 acquires maintenance contract information from the elevator maintenance contract service system, and sets maintenance contract information necessary for building maintenance, device update schedule data, and the like as attribute information in the BIM parts of the elevator. Then, the server device 200 transmits the BIM part to the terminal device 1000 of the building management company. Moreover, the inspection record database (not shown) of the elevator and the BIM system can be linked. For this reason, the attribute of inspection data can be updated to the BIM model which a building management company holds by interlocking with the maintenance information incorporated in the building FM model.

  Moreover, in this embodiment, when it transfers to a renewal stage, the construction process of a BIM system can transfer to a repair phase from a maintenance phase. In the renovation work, the BIM parts managed by the elevator manufacturer can be replaced with the BIM parts of the elevator after the modification, and the update result can be confirmed with a three-dimensional model. The server device 200 has a function of storing a plurality of renewal proposal patterns, and can perform comparative verification.

  In this embodiment, the BIM part of the elevator suitable for a user can be provided for every phase. Furthermore, in this embodiment, by using a support key common to the construction process, the BIM part of the elevator can be specified regardless of the phase. Thereby, a work burden can be reduced.

  In the present embodiment, the BIM part of the elevator on the construction or construction side and the BIM part of the elevator on the elevator manufacturer side can be synchronized via the server device 200. Thereby, data consistency can be maintained.

  Furthermore, in the present embodiment, by accepting selection of the model approval button for each phase of the construction process, it is possible to suppress changes in the BIM parts of the elevator and achieve specification agreement. This simplifies the process of consensus agreement that used to be based on blueprints, etc., and there is a difference between the BIM parts of the elevator that is currently held and the spec that has finally been agreed. Can be suppressed.

  Above, description of an example of the process of the BIM system in embodiment is finished.
