[Process of BIM System in First Embodiment]
Next, an example of processing of the BIM system in the first embodiment configured as described above will be described with reference to FIGS. 4 to 12 (refer to other figures as appropriate). First, an overview of the process will be described with reference to FIGS.

  FIG. 4 is a schematic explanatory diagram regarding creation and display of an integrated BIM model. As shown in FIG. 4, in the present embodiment, for example, in a BIM system, a building BIM model, an equipment BIM model, and an elevator BIM part are integrated to create an integrated BIM model, and a three-dimensional layout screen of the integrated BIM model , And the 3D layout screen (3D layout screen information; the same applies hereinafter) is transmitted to the management facility terminal device 500 and displayed.

  The three-dimensional layout screen will be described with reference to FIGS. FIG. 5 is a diagram showing an example of the layout screen of the elevator of the comparative example (prior art). As shown in FIG. 5, in the comparative example, a planar sectional screen of the building viewed in the vertical direction is displayed on the display monitor, and the elevator is displayed on the screen. Here, elevators ELV1-8, 9, 10, 11, 12 and escalators ESC3, 4 are displayed.

  However, in the actual building, as shown in FIG. 6, the escalator ESC1 exists below the escalator ESC3 in the vertical direction, and the escalator ESC2 exists below the escalator ESC4 in the vertical direction. In the comparative example, because of the planar cross-sectional screen, it is not possible to display both of the escalators that are overlapped when viewed in the vertical direction at the actual position. That is, the elevator layout screen cannot be displayed easily.

  On the other hand, in the present embodiment, as shown in FIG. 7, as the integrated BIM model three-dimensional layout screen, it is possible to display a plurality of escalators overlapping in the vertical direction in the building BIM model at the actual position. it can. That is, the elevator layout screen can be displayed in an easy-to-see manner.

  FIG. 8 is a flowchart illustrating an example of a process for displaying a layout screen by the BIM system according to the first embodiment.

  First, the creation condition transmitting unit 102a of the terminal device 100 transmits the creation condition input by the user using the input unit 118 to the server device 200 (step SA-1). The creation condition receiving unit 202a of the server device 200 receives the creation condition (step SA-2).

  Next, the elevator modeling unit 202b of the server device 200 creates a BIM part corresponding to the creation condition received in Step SA-2 using the part information stored in the part information database 206a (Step SA-3). . For example, the elevator modeling unit 202b creates an elevator BIM part as shown in FIG. Here, in step SA-3, the elevator modeling unit 202b may create a plurality of BIM parts that satisfy the creation conditions.

  Next, the information transmitting / receiving unit 202c of the server device 200 transmits the created BIM part to the terminal device 100 (step SA-4). The information transmitting / receiving unit 102b of the terminal device 100 receives the BIM part (step SA-5).

  Next, the integrated modeling unit 102c of the terminal device 100 creates an integrated BIM model by incorporating one or more BIM parts received in step SA-5 into the BIM model stored in the BIM model database 106a (step SA- 6). For example, the integrated modeling unit 102c creates an integrated BIM model in which elevator BIM parts are incorporated in the BIM model as shown in FIG.

  Next, the transmission control unit 102e of the terminal device 100 creates a 3D layout screen of the integrated BIM model created in Step SA-6 (Step SA-7), and the 3D layout screen is stored in the management facility terminal device 500. Transmit (step SA-8). The management facility terminal device 500 receives the three-dimensional layout screen (step SA-9).

  In step SA-8, it is desirable to transmit only information necessary for displaying the three-dimensional layout screen among the information of the integrated BIM model. For example, information such as a gas pipe, a water pipe, and a beam among the information of the integrated BIM model may not be transmitted. In step SA-8, the data amount may be reduced by simplifying the screen contents. Then, the burden on the line and the management facility terminal device 500 is reduced.

  Next, the control unit 502 of the management facility terminal device 500 displays the three-dimensional layout screen received in Step SA-9 on the display unit 514 (Step SA-10, FIG. 7).

  Thus, according to the present embodiment, it is possible to display the elevator layout screen on the management facility terminal device 500 in an easy-to-view manner using the BIM system. That is, even when the low-rise elevator and the high-rise elevator overlap in the vertical direction, both elevators can be displayed at the actual positions.

  Next, display changes when the layout and specifications are changed for buildings, elevators, and equipment will be described. FIG. 9 is a flowchart showing an example of a work procedure for display change in the comparative example (prior art).

  As shown in FIG. 9, in the comparative example, when there is a change in the layout and specifications of the building (step S1), when there is a change in the layout and specifications of the elevator (step S2), the layout of the equipment and the specifications When there is a change (step S3), the manager of the building requests a software person in charge (such as a technical person in charge of the monitor panel manufacturer) to change the monitor display on the elevator monitor panel (step S4).

  Next, the software staff designs the software (step S5), adjusts the software update schedule (step S6), updates the software (step S7), and finally displays the monitor display on the elevator monitor board. The change is completed (step S8). As described above, in the comparative example, it takes a lot of time and labor to change the display.

  On the other hand, FIG. 10 is a flowchart showing an example of a work procedure for display change by the BIM system in the first embodiment.

  As shown in FIG. 10, in this embodiment, when there is a change in the layout and specifications of the building (step S11), when there is a change in the layout and specifications of the elevator (step S12), the layout and specifications of the equipment. (Step S13), each person in charge registers these changes in the BIM system (terminal device 100, server device 200) (step S14).

  Next, the change is reflected in the integrated BIM model (step S15). Specifically, the integrated modeling unit 102c of the terminal device 100, when at least one of a building BIM model, an equipment BIM model, and an elevator BIM part used for creating the integrated BIM model is updated, is an integrated BIM model database. The integrated BIM model of 106b is updated.

  Next, the updated integrated BIM model is output to the elevator monitor board monitor (step S16). Specifically, the transmission control unit 102e of the terminal device 100 creates a three-dimensional layout screen of the updated integrated BIM model, transmits it to the management facility terminal device 500, and displays it. Thus, the change of the monitor display on the elevator monitoring panel is completed (step S17). Thus, in this embodiment, the display change requires little time and effort. That is, there is almost no work only for the display change.

  Next, display of an evacuation route will be described with reference to FIGS. FIG. 11 is a diagram illustrating an example when an evacuation route that avoids a location where the fire shutter is closed is displayed on the three-dimensional layout screen of the integrated BIM model in the first embodiment.

  The evacuation route determination unit 102d of the terminal device 100 refers to the integrated BIM model database 106b and determines an evacuation route in the integrated BIM model while avoiding a location where the fire shutter corresponding to the fire shutter BIM model is closed. At that time, the transmission control unit 102e transmits the determined evacuation route to the management facility terminal device 500 so as to be displayed on the three-dimensional layout screen of the integrated BIM model. Thereby, in the management facility terminal device 500, the control unit 502 can display the evacuation route on the three-dimensional layout screen of the integrated BIM model of the display unit 514.

  Specifically, it is assumed that the evacuation route from the position of the 4F human object to the 2F entrance is determined on the 3D layout screen of FIG. Assuming that there is a fire near the 3F fire shutter and the fire shutter is closed, avoid the fire shutter, do not go through the 3F escalator, decide the evacuation route through the 3F stairs and 2F escalator, indicate. In this way, an appropriate evacuation route can be determined and displayed in a three-dimensional manner.

  For example, when there are a plurality of fire shutters, the management facility terminal device 500 notifies the terminal device 100 of which fire shutter has been closed, uses the information to determine an evacuation route, and the evacuation The route may be transmitted from the terminal device 100 to the management facility terminal device 500, and the management facility terminal device 500 may display the evacuation route.

  For example, when there are a plurality of fire shutters, the terminal device 100 determines each evacuation route for all combinations of fire shutters that are closed, and the terminal device 100 performs all evacuation to the management facility terminal device 500. You only have to send the route. Then, the management facility terminal device 500 can display the evacuation route corresponding to the fire shutter that is actually closed.

  Next, FIG. 12 is a diagram illustrating an example of a case where an evacuation route that avoids the detection area of the smoke sensor that detects smoke is displayed on the three-dimensional layout screen of the integrated BIM model in the first embodiment. is there.
