Description

[Technical Field]

[0001] The present invention , established Regarding the Planning Support Program. [Background technology]

[0002] In recent years, the construction industry has been promoting the introduction of BIM (Building Information Modeling) in order to improve productivity through the use of ICT (Information and Communication Technology) in its operations.

[0003] BIM is a method of constructing a model of the objects that make up a building, which includes attribute information such as name, dimensions, materials, component specifications, and performance in addition to shape information.

[0004] The objects correspond to architectural elements such as walls and equipment, and the shape information corresponds to CAD (Computer Aided Design) data, for example.

[0005] Technologies have been proposed to support the design of buildings using computers. Design using BIM is one example of computer-aided design of buildings.

[0006] For example, Patent Document 1 discloses a technology that limits changes to the shape of a model based on the installation space and the allowable number of bowls when designing a hand washing counter using BIM. The technology disclosed in Patent Document 1 prevents rework in the design.

[0007] For example, Patent Document 2 discloses an estimation system for water pipes that calculates the type and quantity of required pipe components based on plumbing fixtures and joint components. [Prior art documents] [Patent documents]

[0009] However, in conventional technologies, when designing a building using a computer, it is sometimes not possible to provide the user with the part numbers of the necessary components in response to intuitive operations.

[0010] For example, the technology described in Patent Document 1 does not notify the user of the product number. Also, the technology described in Patent Document 2 requires the user to input detailed conditions to know the product number, which is not intuitive. [Means for solving the problem]

[0011] BIM data according to one aspect of the embodiment is BIM data relating to equipment installed in a building, and has attribute information including parameters that can be changed by user operation, a parameter that determines the connection position between the building and the equipment, and a parameter that changes depending on the parameter that determines the connection position, a parameter that determines the part number of a component depending on the connection position, and shape information for displaying the three-dimensional shape of the equipment reflecting the parameters.

[0012] A design support program according to one aspect of the embodiment causes a computer to execute the following steps: a first update procedure for updating a parameter included in attribute information of BIM data relating to equipment installed in a building, the parameter determining the connection position between the building and the equipment, in accordance with a value input by a user; a second update procedure for updating a parameter included in the attribute information, the parameter determining the part number of a component corresponding to the connection position, in accordance with the parameter determining the connection position; a first display control procedure for displaying, on a display unit, a three-dimensional shape of the equipment reflecting the parameter determining the connection position updated in the first update procedure, in accordance with shape information included in the BIM data; and a second display control procedure for displaying, on the display unit, information regarding the part number indicated by the parameter determining the part number of the component updated in the second update procedure. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, embodiments of the BIM data and the design support program according to the present application will be described in detail with reference to the drawings. However, the present invention is not limited to the embodiments described below.

[0016] First, the configuration of a design support system according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing an example of the configuration of a design support system according to an embodiment.

[0017] 1, the design support system 1 includes a server 10 and a terminal device 20. The number of servers 10 and terminal devices 20 is not limited to those shown in FIG.

[0018] The server 10 and the terminal device 20 are connected via a network N. The network N is, for example, the Internet.

[0019] The server 10 provides BIM data to the terminal device 20. The terminal device 20 executes a BIM application using the BIM data acquired from the server 10. The terminal device 20 is, for example, a personal computer, a smartphone, a tablet terminal, or the like.

[0020] A BIM application is an application for designing buildings using BIM. For example, an example of a BIM application is Revit (registered trademark) from Autodesk (registered trademark).

[0021] BIM data is data used to construct BIM parts in a BIM application. BIM data includes geometric information for displaying the 3D shape of the BIM parts and attribute information, which is a set of parameters.

[0022] A BIM part may be created for each building element that is placed in the BIM model of a building.

[0023] As shown in FIG. 1, the terminal device 20 is operated by a developer or a designer.

[0024] For example, the developer belongs to an equipment manufacturer and uses a BIM application installed on the terminal device 20 to create BIM data related to the equipment.

[0025] Furthermore, for example, a designer may belong to a design office, a construction company, or the like, and design a building using a BIM application installed on the terminal device 20. For example, the designer performs an operation to place BIM parts constructed from BIM data on a BIM model of the building.

[0026] The configuration of the server 10 will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example of the configuration of the server according to the embodiment.

[0027] As shown in FIG. 2, the server 10 includes a communication unit 11, a storage unit 12, and a control unit 13.

[0028] The communication unit 11 performs data communication with other devices via a network. For example, the communication unit 11 is a network interface card (NIC).

[0029] The storage unit 12 is a storage device such as a hard disk drive (HDD) or an optical disk, or a semiconductor memory such as a solid state drive (SSD), a random access memory (RAM), or a flash memory.

[0030] The storage unit 12 stores an OS (Operating System) and various programs executed on the server 10. The storage unit 12 stores shape information 121 and attribute information 122.

[0031] The shape information 121 and the attribute information 122 are included in the BIM data. The BIM data will be explained using Fig. 3. Fig. 3 is a diagram for explaining the BIM data.

[0032] In the example of Fig. 3, shape information 121 of the BIM data is information for displaying the three-dimensional shape of a toilet. For example, the shape information 121 is 3D CAD data. Also, in the example of Fig. 3, attribute information 122 of the BIM data is a set of parameters related to the toilet.

[0033] The attribute information 122 also includes the name and value of a parameter. For example, Fig. 3 shows that the value of the parameter "water supply unit" is "5.000000".

[0034] The control unit 13 controls the entire server 10. The control unit 13 is realized by, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), a GPU (Graphics Processing Unit), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or the like.

[0035] The control unit 13 executes a program to function as, for example, a storage unit 131 and a providing unit 132.

[0036] The storage unit 131 stores the shape information 121 and the attribute information 122 in the memory unit 12. For example, the storage unit 131 stores BIM data provided by a developer via the terminal device 20 in the memory unit 12 as the shape information 121 and the attribute information 122.

[0037] The providing unit 132 provides the shape information 121 and the attribute information 122 to the terminal device 20. For example, when a request to download BIM data is made to the server 10 via a website, the providing unit 132 provides the shape information 121 and the attribute information 122 as BIM data.

[0038] The configuration of the terminal device 20 will be described with reference to Fig. 4. Fig. 4 is a diagram showing an example of the configuration of the terminal device according to the embodiment.

[0039] As shown in FIG. 4, the terminal device 20 includes a communication unit 21, an input unit 22, a display unit 23, a storage unit 24, and a control unit 25.

[0040] The communication unit 21 performs data communication with other devices via a network. For example, the communication unit 11 is a NIC.

[0041] The input unit 22 accepts data input from a user. For example, the input unit 22 is an input device such as a mouse and a keyboard. In the following description, unless otherwise specified, the user refers to a designer.

[0042] The display unit 23 displays a screen. For example, the display unit 23 is a display device such as a display.

[0043] The storage unit 24 is a storage device such as an HDD or an optical disk, or a semiconductor memory such as an SSD, a RAM, or a flash memory.

[0044] The storage unit 24 stores an OS and various programs executed on the terminal device 20. The storage unit 24 stores shape information 241, attribute information 242, and application information 243.

[0045] The shape information 241 and the attribute information 242 are included in the BIM data provided by the server 10.

[0046] The application information 243 is information for executing a BIM application. For example, the application information 243 is a set of files for executing a BIM application on the terminal device 20.

[0047] 5 is a diagram showing an example of an execution screen of a BIM application. As shown in FIG. 5, the execution screen of the BIM application displayed on the display unit 23 includes a property window 231 and a drawing area 232.

[0048] The property window 231 is a window for displaying and changing attribute information 242 related to the BIM part. The drawing area 232 is an area where a projection drawing of the three-dimensional shape of the BIM part is drawn in accordance with the shape information 241.

[0049] Here, the BIM data in the embodiment is assumed to be BIM data related to a toilet. The BIM data includes shape information 241 and attribute information 242.

[0050] The attribute information 242 is a parameter that can be changed by a user operation, and includes a parameter that determines the water supply position of the toilet. The shape information 241 is information for displaying the three-dimensional shape of the toilet that reflects the parameters. For example, the shape information 241 is 3D CAD data.

[0051] Fig. 6 is a diagram for explaining parameters relating to the water supply position and the product number of the water supply hose. "Water supply distance" and "water supply left / right" in Fig. 6 are parameters relating to the water supply position.

[0052] The parameter "water supply distance" corresponds to the distance between the water supply position on the building side and the water supply position on the toilet side in the three-dimensional shape. Note that the distance between the water supply position on the building side and the water supply position on the toilet side may be determined by parameters corresponding to each of the three-dimensional components, including the horizontal distance and the vertical distance.

[0053] The parameter "left / right water supply" is a parameter that determines whether the toilet bowl has a left water supply or a right water supply.

[0054] The parameters "water supply distance" and "water supply left / right" can be changed by the designer.

[0055] The parameters "Water supply hose part number: standard hose," "Water supply hose part number: TN111L86," "Water supply hose part number: TN111L552," "Water supply hose part number: TN111L45," "Water supply hose part number: TN111L40," and "Water supply hose part number: TN111L37" indicate whether the water supply hose of each part number is appropriate for the water supply position. In the following explanation, these parameters may be referred to as the parameters for each part number.

[0056] A "Yes" parameter value for each product number means that the water supply hose corresponding to that product number is appropriate for the water supply position, whereas a "No" parameter value for each product number means that the water supply hose corresponding to that product number is not appropriate for the water supply position.

[0057] The parameter value for each product number is not limited to "yes / no" and may be any value that can express appropriateness or non-appropriateness in binary, such as "1 / 0" or "TRUE / FALSE".

[0058] Furthermore, the parameter for expressing the appropriate product number need not be prepared for each product number as in the embodiment, but may have as its value an appropriate product number according to the water supply position.

[0059] Figure 6 shows that the water supply hose with part number "TN111L45" is suitable, but other water supply hoses are not suitable.

[0060] The values ​​of the parameters "water supply distance" and "water supply location" may be fixed values ​​determined by the developer, values ​​manually entered by the designer, or values ​​dynamically determined according to a formula.

[0061] Here, manufacturers and the like may provide information for identifying an appropriate water supply hose according to the water supply position, as shown in Fig. 7. Fig. 7 is a diagram illustrating an example of information regarding the length of the water supply hose according to the water supply position.

[0062] Furthermore, the length and water supply position (stop valve installation range) may be specified for each product number of the water supply hose, as shown in Figure 8. Figure 8 is a diagram showing an example of information related to the water supply hose.

[0063] The parameter equations for each part number in FIG. 6 represent information for selecting an appropriate water supply hose as shown in FIGS.

[0064] For example, the formula "=IF(OR(AND(Water supply left / right="left water supply", 550≦water supply distance<700), AND(Water supply left / right="right water supply", 350≦water supply distance<500)))" for the parameter "Water supply left / right" means that if the value of the parameter "Water supply left / right" is "left water supply" and the value of the parameter "Water supply distance" is 550 or more and less than 700, or if the value of the parameter "Water supply left / right" is "right water supply" and the value of the parameter "Water supply distance" is 350 or more and less than 5000, then the value of the parameter "Water supply hose model number: standard" will be "Yes", and otherwise the value will be "No".

[0065] The control unit 25 controls the entire terminal device 20. The control unit 25 is realized by, for example, a CPU, an MPU, a GPU, an ASIC, an FPGA, or the like.

[0066] The control unit 25 functions as an acquisition unit 251, a display control unit 252, and an update unit 253. The acquisition unit 251, the display control unit 252, and the update unit 253 execute a design support program.

[0067] The design support program may be implemented as one function of a BIM application, or may be an add-in program for the BIM application.

[0068] The acquisition unit 251 acquires BIM data from the server 10. The acquisition unit 251 stores the acquired BIM data in the storage unit 24 as shape information 241 and attribute information 242.

[0069] The display control unit 252 executes a first display control procedure and a second display control procedure, and the update unit 253 executes a first update procedure and a second update procedure.

[0070] The display control unit 252 displays a projection drawing of the 3D shape of the toilet, which is a BIM part, in the drawing area 232 based on the shape information 241. In addition, the display control unit 252 displays information on each parameter of the toilet, which is a BIM part, in the property window 231 based on the attribute information 242.

[0071] Here, the update unit 253 updates the parameters included in the attribute information 242 of the BIM data regarding the equipment installed in the building, which determine the connection position between the building and the equipment, according to the value input by the user.

[0072] Furthermore, the update unit 253 updates the parameter included in the attribute information 242 and used to determine the part number of the component depending on the connection position, in accordance with the parameter that determines the connection position.

[0073] In the embodiment, the equipment corresponds to a toilet. The connection position corresponds to the water supply position of the toilet. The parameters "water supply distance" and "water supply left / right" are examples of parameters that determine the connection position between the building and the equipment. The parameters for each product number are examples of parameters that determine the product number of a component according to the connection position.

[0074] That is, the update unit 253 updates the parameter that determines the water supply position of the toilet installed in the building as the connection position according to the value input by the user. Also, the update unit 253 updates the parameter that determines the product number of the water supply hose, which is a component, according to the parameter that determines the connection position.

[0075] The display control unit 252 causes the display unit 23 to display the three-dimensional shape of the equipment, reflecting the parameters that determine the connection positions updated by the update unit 253, in accordance with the shape information 241 included in the BIM data.

[0076] Furthermore, the display control unit 252 causes the display unit 23 to display information relating to the part number indicated by the parameter for determining the part number of the component updated by the update unit 253.

[0077] The display control unit 252 displays whether the parameter value for each product number is "Yes" or "No" in the property window 231. This allows the user to see the property window 231 and determine the product number of the appropriate water supply hose.

[0078] The display control unit 252 may notify the user of the product number of the appropriate water supply hose without using the property window 231.

[0079] For example, the display control unit 252 may notify the user by displaying a pop-up message, changing the color of graphics and text on the screen, or the like.

[0080] Furthermore, the terminal device 20 may notify the user of the product number of the appropriate water supply hose by voice.

[0081] (Variation) The display control unit 252 may display an image showing the relationship between the connection position and the product number of the water supply hose, as shown in Fig. 7, in the drawing area 232. In this case, for example, the display control unit 252 may superimpose the image on the toilet bowl in a transparent manner.

[0082] 6, the parameter for each product number in the attribute information 242 has a value indicating whether the water supply hose of each product number is appropriate for the connection position. On the other hand, the attribute information 242 may also include a parameter indicating detailed information about the water supply hose of each product number.

[0083] For example, the attribute information 242 may include a parameter indicating the URL of a website that provides details of each water supply hose model number, or a parameter indicating the range of water supply distances that correspond to each water supply hose model number.

[0084] 9 is a flowchart showing the flow of the design support process. The terminal device 20 can execute the design support process using a design support program.

[0085] First, the terminal device 20 acquires BIM data from the server 10 (step S101). Next, the terminal device 20 starts up a BIM application (step S102).

[0086] Next, the terminal device 20 displays the three-dimensional shape of the toilet according to the BIM data (step S103).

[0087] Here, the terminal device 20 displays the product number of the water supply hose determined from the set water supply position (step S104). The water supply position is specified by the above-mentioned parameters "water supply distance" and "water supply left / right".

[0088] Thereafter, the terminal device 20 continues to display the three-dimensional shape and waits (step S103) until the user changes the value of the water supply position of the toilet bowl (step S105, No).

[0089] If the user has changed the water supply position (step S105, Yes), the terminal device 20 updates the BIM data according to the changed value (step S106). After that, the terminal device 20 returns to step S103.

[0090] This allows the product number of the water supply hose to be displayed to be switched depending on the change in water supply position made by the user.

[0091] As explained so far, BIM data is BIM data related to equipment installed in a building, and has attribute information including parameters that can be changed by user operation and determine the connection position between the building and the equipment, and parameters that change depending on the parameters that determine the connection position and determine the part number of the component depending on the connection position, and shape information for displaying the three-dimensional shape of the equipment reflecting the parameters.

[0092] In this way, appropriate part numbers for components can be obtained from BIM data according to parameters related to the equipment connection positions. As a result, according to the embodiment, in computer-aided building design, the part numbers of necessary components can be provided in response to intuitive operations by the user.

[0093] The design support program causes a computer to execute the following steps: a first update procedure, which updates a parameter included in attribute information of BIM data related to equipment to be installed in a building, which determines the connection position between the building and the equipment, in accordance with a value input by a user; a second update procedure, which updates a parameter included in the attribute information, which determines the part number of a component corresponding to the connection position, in accordance with the parameter that determines the connection position; a first display control procedure, which causes a display unit to display, in accordance with shape information included in the BIM data, a three-dimensional shape of the equipment that reflects the parameter that determines the connection position updated in the first update procedure; and a second display control procedure, which causes a display unit to display information related to the part number indicated by the parameter that determines the part number of the component updated in the second update procedure.

[0094] In this way, the design support program can obtain appropriate part numbers for components according to parameters related to the equipment connection positions. As a result, according to the embodiment, in computer-aided architectural design, the part numbers of necessary components can be provided in response to intuitive operations by the user.

[0095] The first update procedure updates the parameter that determines the water supply position of the toilet to be installed in the building as the connection position according to the value input by the user, and the second update procedure updates the parameter that determines the product number of the water supply hose, which is a component, according to the parameter that determines the connection position. This makes it possible to inform the user of the product number of the appropriate water supply hose according to the water supply position of the toilet in computer-aided building design.

[0096] Further advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
