May be.

  The elevator modeling unit 202b creates, for example, a three-dimensional BIM part of an elevator as shown in FIG. Here, FIG. 3 is a diagram showing an example of the BIM parts of the elevator.

The elevator BIM part created by the elevator modeling unit 202b includes attribute information such as part information related to the target elevator in the BIM part itself.

  Based on the simulation conditions related to the input elevator, the building information related to the building included in the BIM model, and the BIM parts created by the elevator modeling unit 202b, the analysis unit 202c is stored in the calculation formula file 206b.

Further, here, various simulations will be described in the case where the elevator is an elevator, but the simulation can also be applied when the elevator is a passenger conveyor. When the elevator is a passenger conveyor, the hoistway corresponds to a space part where a user gets on and a step or the like moves.

  The analysis unit 202c typically represents a building represented by the BIM model based on the input simulation conditions, the building information related to the building included in the target BIM model, and the BIM part created by the elevator modeling unit 202b. A simulation (wind pressure simulation) is performed on a wind pressure change in the hoistway that occurs when the elevator represented by the BIM part travels within the object. The analysis unit 202c executes a wind pressure simulation using a calculation formula relating to a wind pressure change stored in the calculation formula file 206b. Various known calculation formulas may be used as calculation formulas related to the wind pressure change. In this case, the analysis unit 202c acquires, for example, simulation conditions, building information of the BIM model of the target building, and part information (part simulation information and the like) of the created BIM part.

I do.

  For example, when an elevator travels at a high speed on a hoistway where the car is narrow, the air in the forward direction of the car is compressed and the air pressure is increased, while the air pressure behind the car is reduced. And the wind pressure change in the hoistway is caused by the air flowing forward (high pressure side) in the moving direction of the car vigorously flowing backward (low pressure side) in the moving direction through the gap between the car and the hoistway wall. . The wind pressure in the hoistway is the structure, shape, dimensions, material, event and parts simulation information included in the building information (hoistway space information), shape, dimensions, material, event, It changes with the traveling of the car according to the transmission loss of various wall surfaces. The analysis unit 202c uses the calculation formula related to the wind pressure change based on the simulation conditions, the building information of the BIM model, the part simulation information of the BIM parts, and the like, and the wind pressure change in the hoistway that occurs when the elevator moves as described above Calculate

  Similarly, the analysis unit 202c is configured to input the simulation condition, the building information related to the building included in the target BIM model, and the BIM part created by the elevator modeling unit 202b. The simulation (noise simulation) regarding the noise generated when the elevator represented by the BIM part travels is executed. The analysis unit 202c executes a noise simulation using a calculation formula relating to noise stored in the calculation formula file 206b. Various known calculation formulas may be used as the calculation formula for noise. In this case, the analysis unit 202c acquires, for example, simulation conditions, building information of the BIM model of the target building, and part information (part simulation information and the like) of the created BIM part. And the analysis part 202c performs the noise calculation which generate | occur | produces when the elevator which a BIM part travels in the building which a BIM model represents based on such information and the information memorize | stored in the calculation formula file 206b.

  For example, in an elevator, the wind pressure in the hoistway that is generated when the air in the forward direction (high-pressure side) of the car flows vigorously backward (low-pressure side) through the gap between the car and the hoistway wall. The acoustic energy and the sound pressure change according to changes, operating states of various devices, the lift position of the car, and the like. For example, the narrower the gap between the car and the hoistway wall, the greater the speed of the air flow (wind speed), and the greater the wind noise, the greater the noise. Noise is the structure, shape, dimensions, material, event and parts simulation information included in building information (hoistway space information), shape, dimensions, material, event, transmission loss of various wall surfaces. It changes with the traveling of the car according to the etc. The analysis unit 202c calculates noise in the hoistway generated during the traveling of the elevator as described above using a calculation formula relating to noise based on simulation conditions, building information of the BIM model, parts simulation information of the BIM parts, and the like. To do. In this case, the analysis unit 202c may individually calculate various noises such as in-car noise, hoistway noise, machine room noise, adjacent room noise, and duct noise.

  Similarly, the analysis unit 202c is configured to input the simulation condition, the building information related to the building included in the target BIM model, and the BIM part created by the elevator modeling unit 202b. The simulation (vibration simulation) regarding the vibration generated when the elevator represented by the BIM part travels is executed. The analysis unit 202c executes a vibration simulation using a calculation formula relating to vibration stored in the calculation formula file 206b. Various known calculation formulas may be used as calculation formulas related to vibration. In this case, the analysis unit 202c acquires, for example, simulation conditions, building information of the BIM model of the target building, and part information (part simulation information and the like) of the created BIM part. And the analysis part 202c performs the vibration calculation which generate | occur | produces at the time of the driving | running | working of the elevator which a BIM part represents based on such information and the information memorize | stored in the calculation formula file 206b.

  For example, in an elevator, the wind pressure in the hoistway that is generated when the air in the forward direction (high-pressure side) of the car flows vigorously backward (low-pressure side) through the gap between the car and the hoistway wall. The vibration energy changes according to the change, the operating state of various devices, the lift position of the car, and the like. Vibration is the structure, shape, dimensions, material, event and parts simulation information included in the building information (hoistway space information), shape, dimensions, material, event, transmission loss of various wall surfaces. It changes with the traveling of the car according to the etc. The analysis unit 202c calculates vibrations in the hoistway generated during the traveling of the elevator as described above using a calculation formula related to vibration based on simulation conditions, building information of the BIM model, parts simulation information of the BIM parts, and the like. To do. In this case, the analysis unit 202c may individually calculate vibrations at various places such as in-car vibration, hoistway vibration, machine room vibration, adjacent room vibration, and duct vibration.

  Based on the results of various simulations related to wind pressure change, noise, and vibration executed by the analysis unit 202c, the automatic creation unit 202d uses BIM parts reflecting the simulation results as part information stored in the parts information database 206a. It is an automatic creation means that creates automatically by using.

  The automatic creation unit 202d typically sets a wind pressure allowable value in which the wind pressure in the hoistway generated when the elevator represented by the BIM part travels is set based on the result of the wind pressure simulation executed by the analysis unit 202c. If it exceeds, a BIM part reflecting the result of the wind pressure simulation may be automatically created. In this case, the automatic creation unit 202d creates a BIM part in which the wind pressure in the hoistway calculated by the wind pressure simulation is equal to or lower than the allowable wind pressure using the part information stored in the part information database 206a. Here, the allowable wind pressure value is a value corresponding to the designated value of the allowable wind pressure value included in the simulation condition as described above.

  Similarly, the automatic creation unit 202d typically has a preset noise level in the hoistway generated when the elevator represented by the BIM part travels based on the result of the noise simulation performed by the analysis unit 202c. If the allowable value is exceeded, a BIM part reflecting the result of the noise simulation may be automatically created. In this case, the automatic creation unit 202d creates, using the part information stored in the part information database 206a, a BIM part in which the noise in the hoistway calculated by the noise simulation is equal to or less than the allowable noise value. When any one of the noise in the car, the noise in the hoistway, the noise in the machine room, the noise in the adjacent room, and the noise in the duct exceeds the noise allowable value, the automatic creation unit 202d performs BIM as described above. Parts may be created automatically, or BIM parts may be created automatically as described above when all noise exceeds the allowable noise level. Here, the allowable noise value is a value corresponding to the specified value of the allowable noise value included in the simulation condition as described above.

  Similarly, the automatic creation unit 202d typically has a vibration in which a vibration in the hoistway generated when the elevator represented by the BIM part travels is preset based on the result of a vibration simulation executed by the analysis unit 202c. If the allowable value is exceeded, a BIM part reflecting the result of the vibration simulation may be automatically created. In this case, the automatic creation unit 202d creates, using the part information stored in the part information database 206a, a BIM part in which the vibration in the hoistway calculated by the vibration simulation is equal to or less than the allowable vibration value. When any one of the vibration in the car, the vibration in the hoistway, the vibration in the machine room, the vibration in the adjacent living room, and the vibration in the duct exceeds the respective vibration allowable values, the automatic creation unit 202d performs BIM as described above. Parts may be created automatically, or BIM parts may be created automatically as described above when all vibrations exceed the allowable vibration value. Here, the allowable vibration value is a value corresponding to the specified value of the allowable vibration value included in the simulation condition as described above.

  The information providing unit 202e is an information providing unit that transmits the BIM part created by the elevator modeling unit 202b and the results of wind pressure simulation, noise simulation, and vibration simulation executed by the analysis unit 202c to the terminal device 100.

That is, the screen display unit 102d sets a space at a noise level that is equal to or slightly higher than each allowable noise value as “required level” in red, and a space at a noise level slightly lower than the allowable noise value as “attention level”. A space which is yellow and has a noise level sufficiently lower than the allowable noise level is displayed as a “no problem level” in white (or blue) in different colors and displayed on the display unit 114. Similarly, the screen display unit 102d sets a space at a vibration level that is equal to or slightly higher than each vibration allowance as a “required level” in red, and a space at a vibration level slightly lower than the vibration allowance as an “attention level”. A space having a vibration level that is yellow and sufficiently low with respect to the permissible vibration value is displayed as a “no problem level” in white (or blue) in different colors and displayed on the display unit 114. The screen display unit 102d may cause the display unit 114 to display the color-coded noise and vibration in conjunction with the traveling pattern of the elevator represented by the BIM part.

And compare. The analysis unit 202c determines whether or not the calculated wind pressure, typically the wind pressure acting on the hoistway wall, is equal to or less than a specified value of the allowable wind pressure value (step SA-44).

  If the analysis unit 202c of the server apparatus 200 determines in step SA-44 that the wind pressure is equal to or less than the specified value of the allowable wind pressure value in step SA-44 (step SA-44: Yes), step SA-43 is performed. The result of the wind pressure calculation calculated by the process of the analysis unit 202c is determined as the result of the wind pressure simulation transmitted as BIM information to the terminal device 100 (step SA-45), and this process ends.

  If the automatic creation unit 202d of the server device 200 determines in step SA-44 that the wind pressure has exceeded the specified value of the allowable wind pressure value by the processing of the analysis unit 202c (step SA-44: No), the following processing is performed.

  If the analysis unit 202c of the server device 200 determines in step SA-48 that the intention of permitting the change is indicated by the process of the analysis unit 202c (step SA-48: Yes), the process proceeds to step SA-46. Based on the various parameters of the elevator BIM parts created by the processing of the automatic creation unit 202d, the parameters required for the alternative wind pressure simulation are designated (step SA-49).

  Then, the analysis unit 202c of the server device 200 calculates the parameters required for the alternative wind pressure simulation specified by the processing of the analysis unit 202c in step SA-49 and the wind pressure change stored in the calculation formula file 206b. Based on the equation, the wind pressure in the hoistway generated when the elevator represented by the BIM part travels is calculated (step SA-50).

Further, the terminal device 100 is also configured for each part of the storage unit 406 (part information database 406a as a part information storage unit, BIM model database 406b as a BIM model storage unit, and a calculation formula file 406c as a calculation formula storage unit). Since the functions are substantially the same as those of the first embodiment except that the BIM device 400 is provided instead of the server device 200, the description thereof will be omitted as much as possible.

  Among these, the parts information database 406a is a part information storage unit that stores part information for creating BIM parts of an elevator that can be incorporated into a BIM model of a building.

  The BIM model database 406b is a BIM model storage unit that stores a BIM model of a building.

A layout screen is generated based on the results of wind pressure simulation, noise simulation, and vibration simulation (step SC-6).

  Then, the screen display unit 402f causes the display unit 414 to display the layout screen generated by the process of the screen generation unit 402e in step SC-6 (step SC-7), and ends this process. For example, the screen display unit 402f causes the display unit 414 to display the layout screen illustrated in FIG.

  If the automatic creation unit 402d determines in step SC-5 that the results of the wind pressure simulation, noise simulation, and vibration simulation do not satisfy the criteria by the processing of the analysis unit 402c (step SC-5: No), the following processing is performed. I do. That is, the automatic creation unit 402d selects BIM parts whose results of the wind pressure simulation, the noise simulation, and the vibration simulation executed by the processing of the analysis unit 402c in Step SC-3 and Step SC-4 satisfy the criteria, as part information. It is automatically created using the parts information stored in the database 406a (step SC-8). For example, the automatic creation unit 402d allows the wind pressure, noise, and vibration based on the results of the wind pressure simulation, the noise simulation, and the vibration simulation executed by the processing of the analysis unit 402c in Step SC-3 and Step SC-4, respectively. BIM parts with values, noise tolerances, and vibration tolerances are automatically created.

  Then, the image display unit 402f uses the information on various parameters of the elevator BIM parts created by the process of the automatic creation unit 402d in step SC-8 as alternatives and countermeasures, and displays the alternatives and countermeasures on the display unit 414. It is displayed and it is confirmed whether change is possible (step SC-9).

  Then, the control unit 402 determines whether or not the user has indicated the intention to permit the change based on the information regarding whether or not the change can be input by the user via the input unit 418 or the like (step SC). -10).

  When it is determined in step SC-10 that the intention of permitting the change is not indicated by the process of control unit 402 (step SC-10: No), control unit 402 performs the process of step SC-. 6. Move to 6. Then, the screen generation unit 402e determines that the standard is not satisfied by the processing of the elevator unit BIM part created by the processing of the elevator modeling unit 402b in step SC-2 and the processing of the analysis unit 402c in step SC-5. A layout screen is generated using the results of wind pressure simulation, noise simulation, and vibration simulation as they are (step SC-6).

  If the analysis unit 402c determines in step SC-10 that the intention of permitting the change is indicated by the process of the control unit 402 (step SC-10: Yes), the automatic generation unit in step SC-8 Based on various parameters of the BIM part of the elevator created by the process of 402d, parameters required for wind pressure simulation, noise simulation, and vibration simulation of the alternative / countermeasure are designated (step SC-11). And the control part 402 transfers a process to step SC-3.

  In this case, the analysis unit 402c performs the wind pressure simulation (step SC-3), the noise and noise based on the parameters required for the simulation of the alternative / measure plan specified by the process of the analysis unit 402c in step SC-11. A vibration simulation (step SC-4) is executed. In this case, in step SC-6, the screen generator 402e analyzes the BIM part of the elevator created by the processing of the elevator modeling unit 402b in step SC-2 and the analysis unit in steps SC-3 and SC-4. A layout screen is generated based on the results of the wind pressure simulation, noise simulation, and vibration simulation of the alternative / countermeasure executed again by the process of 402c (step SC-6). In this case, the screen generation unit 402e also includes the results of the wind pressure simulation, the noise simulation, and the vibration simulation that are determined not to satisfy the criteria by the processing of the analysis unit 402c in step SC-5 as NG results in the layout screen. Also good.
