Description

The present invention relates to a design user terminal, a web catalog server, a design support system, and a design support method.

In architectural design, the first step is to decide on the layout of the building, taking into consideration the site conditions and surrounding environment, and then design the interior and exterior, floor plan, decoration, etc. In this design, not only two-dimensional drawings but also three-dimensional drawings including perspective drawings are created by using a commonly used CAD (Computer-aided design). For buildings designed using this design, structural design is performed to set the foundation and frame, and set the specifications, shapes, and placement of columns, beams, walls, etc., so as to meet safety performance against snow accumulation, earthquakes, etc. This is done after the architectural design. In addition, in parallel with this structural design, or after the structural design, facility design is performed to set up air conditioning equipment for a comfortable indoor environment, sanitary equipment that connects to water and sewage systems, and electrical equipment for locating outlets and lighting. be exposed. The design of the building is completed after the design, structural design, and facility design are changed multiple times while each designer shares information with each other.

By the way, in the design of the above-mentioned buildings, information about the building is shared among designers, architects, construction supervisors, construction contractors, etc. using a BIM (Building Information Modeling) model. There is. Here, a BIM model is information about the shape in a virtual three-dimensional space, materials, dimensions, location, etc. of the building blocks (also called objects, including beams, columns, walls, etc.). It is a three-dimensional model that has information regarding (these are collectively referred to as "specification information"). Using this BIM model, you can create 3D drawings of the 3D model viewed from various angles, cut the 3D drawing in various ways, and create floor plans (including floor plans) viewed from various angles. You can create two-dimensional drawings such as elevation drawings (including frame drawings). In other words, each component constituting the three-dimensional model contains various specification information, and this specification information can be changed, modified, or added, and a history of changes, additions, etc. can be kept.

Here, an information management system using the above-mentioned BIM has been proposed. Specifically, it is an information management system that includes an information processing terminal used by a user and a server device that is communicably connected to the information processing terminal via a network. Here, the server device stores shape information and specification information of an object in association with the object, and stores work information in which an object is associated with a work item related thereto, and resource information in which a work item is associated with a resource item related thereto. a control unit that acquires the information requested by the user using the information processing terminal based on the shape information, specification information, work information, and resource information; and a communication section for transmitting data to an information processing terminal. The information processing terminal also has a display unit that displays a predetermined screen to the user using the information processing terminal based on information requested by the user using the information processing terminal received from the server device via the network. We are prepared.

Japanese Patent Application Publication No. 2013-164681

According to the information management system described in Patent Document 1, information regarding buildings can be managed appropriately and users can easily obtain necessary information. By the way, when designing a BIM model, for example, a designer (structural designer) designs a BIM model using structural calculations, and then performs a A commercially available product (product) that is actually applicable is applied, and the applied product is linked to the object as specification information of the object and input into the design document. When applying this product, for example, since multiple manufacturers sell unique products for the same object, designers need to order paper-based product catalogs from each company and compare them. Web (World wide web) site, and download Web catalogs related to products to obtain them and compare them.

Although it is possible to make catalogs paperless by downloading web catalogs, BIM is difficult because designers manually enter the selected products into the design document database after comparing and considering the products of each manufacturer. Model design takes time and effort.

The present invention has been made in view of the above problems, and provides a design user terminal, a web catalog server, a design support system, and a design support method that can efficiently import product data from manufacturers into a database in a BIM model. It is intended to.

In order to achieve the above object, one aspect of the designed user terminal according to the present invention is as follows:
A design user terminal that communicates with a web catalog server that stores a web catalog and designs a BIM model of a building,
A first intermediate for connecting to the web catalog server via a network and requesting the web catalog server for an object data list that compiles object data of one or more manufacturers regarding objects constituting the BIM model. The first communication department sends the file,
A second intermediate file formed by inputting the object data list to the first intermediate file is received via the first communication unit, and the received second intermediate file is stored. , a first storage section;
When designing a BIM model of a building, the object data list in the second intermediate file stored in the first storage section is read, and object data selected from the object data list is used in the BIM model. and a design department that incorporates the information into the system.

According to this aspect, the first intermediate file is transmitted from the design user terminal to the web catalog server, and the first intermediate file is input with an object data list (product data list) that summarizes object data (product data) of multiple manufacturers. By receiving and storing the second intermediate file in the design user terminal, the design user can design a BIM model using the object data list in the second intermediate file. In other words, since the products related to each object that make up the BIM model are organized into a data list, when a product to be applied to the actual BIM model is selected from the data list, the design documents are automatically entered into the database. Therefore, product data from manufacturers can be efficiently imported into the database in the BIM model.

Here, the design user terminal includes various design user terminals such as a user terminal owned by a person in charge of design, a user terminal owned by a person in charge of structural design, and a user terminal owned by a person in charge of facility design, all of which are personal computers. formed by.

Therefore, for example, if a design user accesses a web catalog server and tries to download all web catalogs at once, the amount of data will be too large and it will take a long time to download, making it difficult to efficiently design a BIM model. I can't. Therefore, in the design user terminal of this aspect, the first communication section transmits the first intermediate file to the Web catalog server. This first intermediate file is, for example, a file that requests an object data list that is a collection of object data from one or more manufacturers regarding one object that is currently being set. Even if there is one manufacturer that handles products related to one object, there are cases where the same manufacturer sells two or more products. Object data regarding the product is input into the object data list, and a second intermediate file is created. On the other hand, even if there are two or more manufacturers that handle products related to one object, since there are two or more products related to the requested object, this data is input into the object data list in the Web catalog server, and the second An intermediate file is created.

In the design user terminal, the second intermediate file into which the object data list is input is received by the first communication unit and stored in the first storage unit. When the design user selects a suitable product from the object data list in the second intermediate file stored in the first storage, the object data related to the product selected from the object data list is added to the target object in the first storage. The selected product data (object data) is automatically input into the target object in the design document database.

Commercially available structural calculation software is installed in the first storage section by downloading, etc., and the structural calculation software is read out in the design department and the designed building is modeled within the structural calculation software. . In this modeling, specification information such as the material (rigidity, etc.), dimensions, and location of each component is input. Then, the structural calculation software executes the structural calculation in the personal computer, and the structural calculation data is stored in, for example, the first storage unit. For example, conversion software is similarly installed on the design user terminal, and this conversion software creates a BIM calculation model from the calculation model (non-BIM calculation model) modeled in the structural calculation software. be done. Then, the selected object data (selected product data, which has already been input into the design document database) is linked as specification information to the target object included in this BIM calculation model.

Further, in another aspect of the design user terminal according to the present invention, the object data list input to the second intermediate file is an object that is a collection of two or more object data provided by two or more manufacturers regarding the same type of object. It is characterized by being a data list.

According to this aspect, since the object data list is a data list that summarizes two or more object data provided by two or more manufacturers regarding the same type of object, the design user can efficiently use the object data list. It is possible to select the most suitable product, and at the same time, input the product data into the design document database.

Further, one aspect of the web catalog server according to the present invention is
A web catalog server that communicates with a design user terminal that designs a BIM model of a building and provides a web catalog to the design user terminal,

The method further includes an input creation unit that creates a second intermediate file by inputting the object data list to the first intermediate file.

According to this aspect, the second storage section stores an object data list that compiles data regarding products of various manufacturers for various objects, and the input creation section stores an object data list regarding the requested object transmitted from the design user terminal. By creating the second intermediate file into which the object data list is input, it is possible to transmit to the design user terminal a data list that can be easily compared and verified by the design user and automatically input into the design documents.

Further, in another aspect of the web catalog server according to the present invention, the input creation unit converts the object data list so that it can be read by application software for designing a BIM model possessed by the design user terminal. The method is characterized in that the second intermediate file is created.

According to this aspect, the input creation unit converts the object data list so that it can be read by the application software for designing a BIM model owned by the design user terminal, and creates the second intermediate file. At the terminal, the selected product data can be quickly linked to the target object of the BIM model using the received second intermediate file. As an example, when Autodesk Revit (registered trademark) (manufactured by Autodesk) is applied as BIM software in the design department of a design user terminal, the first intermediate file is converted into a CSV (Comma Separated Value) format text file or TXT ( Text) format text file to the web catalog server, and the web catalog server sends the stored object data list, such as HTML (HyperText Markup Language) data or PDF (Portable Document Format) data, in CSV or TXT format. can be converted into text data and a second intermediate file can be created. In the design department of the design user terminal, by importing the second intermediate file consisting of CSV text data into BIM software, product data regarding the target object can be automatically input into the design document database as specification information.

Further, one aspect of the design support system according to the present invention is
The designed user terminal;
The web catalog server;

Hereinafter, examples of a design user terminal, a web catalog server, a design support system, and a design support method according to embodiments will be described with reference to the accompanying drawings. Note that in this specification and the drawings, substantially the same constituent elements may be given the same reference numerals to omit redundant explanation.

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

The design support system 50 is formed by connecting the design user terminal 10 and the web catalog server 20 via the network 40, and by similarly connecting the design user terminal 10 and the shared server 30 via the network 40. . The design user terminal 10 includes a design user terminal 10A, a structural design user terminal 10B, a facility design user terminal 10C, etc., and further includes an estimation user terminal, a construction planning user terminal, and an execution user terminal (all not shown). etc., may include various user terminals.

The network 40 includes a public network such as the Internet, a wireless network such as a mobile phone network, a dedicated network such as a VPN (Virtual Private Network), a LAN (Local Area Network), and the like.

Here, the design user terminal 10 and the shared server 30 form a shared system 50A included in the design support system 50, and in the shared system 50A, information is shared only within a company such as a single house builder. In addition to having a closed network, this type has an open network that allows information sharing with external organizations.

In either form, access authority is required to access the shared server 30, and only user terminals to which access authority has been granted can access the shared server 30, and between the shared server 30 and the shared system 50A. , and various data stored in the shared server 30 can be shared. For example, the BIM model described below is stored in the shared server 30 at each design stage, and a design user terminal or an external organization that has been given access authority accesses the shared server 30 and stores the BIM model in the shared server 30. Users can import BIM models currently available on their own terminals, or upload BIM models created on their own terminals to the shared server 30.

Here, in addition to data storage, the shared server 30 may be a cloud server that allows a plurality of users to share various application software. For example, the design user terminal 10 and an external agency terminal (not shown) may use common application software to send and receive BIM data, or when multiple BIM data are sent and received at different times, two arbitrary timings may be used. It may also be possible to compare BIM data of different types of BIM data with each other. Note that the "external agency terminal" may include, in addition to the confirmation application agency terminal, a material and equipment supply manufacturer terminal owned by a material and equipment supply manufacturer that collaborates in the stages of facility design, construction planning, etc.

On the other hand, the web catalog server 20 can be freely accessed with any user terminal without authority, and desired data stored in the web catalog server 20 can be freely obtained without access authority. Access authority may be granted when acquiring data stored in the server 20.

The design design user terminal 10A, the structural design user terminal 10B, and the facility design user terminal 10C are terminals used by a design designer, a structural designer, and a facility designer, respectively, and are formed using a personal computer, tablet, etc. be done.

The BIM model includes a BIM design model designed by a person in charge of design on the design user terminal 10A during the planning stage of a building, a BIM structural model designed by a person in charge of structural design on the structural design user terminal 10B, and the like. At the planning stage, by looking at image data (BIM design model) of a three-dimensionally modeled building, it is possible to directly imagine the appearance, layout design, etc. of the building. In addition, at the facility design stage, we take into account the comfort of the living space by simulating heat flow (flow of wind, air, etc.) inside the building and considering the relationship between lighting placement and the light environment. It is possible to create a design based on Furthermore, at the structural design stage and construction planning stage, by checking 3D images, it is possible to check for interference with equipment, steel frames, piping, etc., and to clearly see details that are difficult to see in 2D drawings. can be grasped.

The web catalog server 20 has web catalogs from a large number of manufacturers regarding various objects that constitute a BIM model.

For objects of the same type, there are cases where only one type of product is commercially available from one manufacturer (there is no room for product selection by the designer), and there are cases where multiple products are commercially available from one manufacturer. In some cases, multiple products are commercially available from multiple manufacturers (there is room for product selection by the designer).

In the Web catalog server 20, an object data list listing commercially available products is created and stored for each of these various objects. For example, when setting a specific product for each object of a BIM model that has undergone structural calculation, the design user accesses the web catalog server 20 and selects a suitable object data list from the object data list stored in the web catalog server 20. Select a product and set the selected product data as specification information for each object in the BIM model.

In the design support system 50, for example, in the structural design stage, a structural design person actually obtains commercially available products from manufacturers for various objects that make up a BIM model (BIM structural model) designed through structural calculations. When setting up a product, the object specification information is automatically entered into the design document. In the following description, data transmission and reception between the design user terminal 10 and the Web catalog server 20 will be explained while keeping in mind the structural design user terminal 10B as the design user terminal 10.

The main storage device 104 and the auxiliary storage device 106 are computer-readable recording media. Note that the above components may be provided individually, or some components may not be provided.

The CPU 102 is also called an MPU (Microprocessor) or a processor, and the CPU 102 may be a single processor or a multiprocessor. The CPU 102 is a central processing unit that controls the entire design user terminal 10 and the like made up of a computer. For example, the CPU 102 develops a program stored in the auxiliary storage device 106 in an executable manner in the work area of the main storage device 104, and controls peripheral devices through the execution of the program, thereby executing functions that meet a predetermined purpose. I will provide a.

The main storage device 104 stores computer programs executed by the CPU 102, data processed by the CPU 102, and the like. The main storage device 104 includes, for example, flash memory, RAM (Random Access Memory), and ROM (Read Only Memory). The auxiliary storage device 106 stores various programs and various data on a recording medium in a readable and writable manner, and is also called an external storage device. The auxiliary storage device 106 stores, for example, an OS (Operating System), various programs, various tables, and the like. The OS includes, for example, a communication interface program that exchanges data with an external device connected via the communication IF 108. External devices include, for example, information processing devices such as personal computers (PCs), workstations (WS), servers, and mobile terminals connected to a network, external storage devices, and the like.

The auxiliary storage device 106 is used, for example, as a storage area to supplement the main storage device 104, and stores computer programs executed by the CPU 102, data processed by the CPU 102, and the like. The auxiliary storage device 106 is a silicon disk including a nonvolatile semiconductor memory (flash memory, EPROM (Erasable Programmable ROM)), a hard disk drive (HDD) device, a solid state drive device, or the like. Further, as the auxiliary storage device 106, a removable recording medium drive device such as a CD drive device, a DVD drive device, and a BD drive device is exemplified. Examples of removable recording media include CDs, DVDs, BDs, USB (Universal Serial Bus) memories, and SD (Secure Digital) memory cards.

The communication IF 108 is an interface with the network 40 to which the design user terminal 10 and the like are connected. The communication IF 108 transmits the first intermediate file to the web catalog server 20 and receives the second intermediate file from the web catalog server 20 via the network 40. Further, the communication IF 108 stores the BIM model designed at the design user terminal 10 in the shared server 30 and receives the BIM model stored in the shared server 30 via the network 40 .

The input/output IF 110 is an interface that inputs and outputs data with devices connected to the design user terminal 10 and the like. For example, a keyboard, a pointing device such as a touch panel or a mouse, an input device such as a microphone, etc. are connected to the input/output IF 110. The design user terminal 10 and the like receive operation instructions and the like from an operator who operates an input device via the input/output IF 110.

Further, the input/output IF 110 is connected to, for example, a display device such as a liquid crystal display (LCD) or an organic EL panel (electroluminescence), an output device such as a printer, or a speaker. The design user terminal 10 and the like output data and information processed by the CPU 102 and data and information stored in the main storage device 104 and the auxiliary storage device 106 via the input/output IF 110.

As shown in FIG. 3, the design user terminal 10 provides various functions of at least a first communication section 120, a first input/output section 122, a design section 124, and a first storage section 126 by executing a program by the CPU 102. do. Note that at least a part of the above processing function may be provided by a DSP (Digital Signal Processor), a GPU (Graphics Processing Unit), etc. Similarly, at least a part of the above processing function may be provided by an FPGA (Field-Programmable Gate). It may also be a dedicated LSI (large scale integration) such as an array), a numerical arithmetic processor, an image processing processor, or other digital circuits.

The first communication unit 120 transmits the first intermediate file created at the design user terminal 10 to the web catalog server 20, receives the second intermediate file created at the web catalog server 20, and stores the first intermediate file. The information is stored in the section 126. Further, the first communication unit 120 transmits the BIM model created at the design user terminal 10 to the shared server 30 and receives the BIM model stored in the shared server 30.

Here, an example of the first intermediate file will be described with reference to FIG. 4. The first intermediate file 60 is, for example, when a structural design person sets a specific product for each object of a BIM model for which structural calculations have been performed, and requests information regarding the target object from the web catalog server 20. This is the file to be used.

The first intermediate file 60 shown as an example in FIG. 4 is transmitted to the Web catalog server 20 as a file in CSV format or TXT format, for example. In the first intermediate file 60, the requested object 61, part 62, installation floor 63, installation position 64, manufacturer name 65, product name 66, etc. are input as text data from the top. Note that the file contents may have various items and orders, and the illustrated example is merely an example.

In the example shown in FIG. 4, in the first intermediate file 60, a wall is set as the requested object 61, a base material is set as the wall part 62, 1FL is set as the installation floor 63, and X1 types are set as the installation position. X1Y1, which is the intersection of Y1 ways or the vicinity of the intersection, is set. The manufacturer name 65 and product name 66 set for this object are undetermined in the first intermediate file 60.

The web catalog server 20 includes, for example, web catalogs from multiple manufacturers regarding various objects. Therefore, for example, if a design user accesses the web catalog server 20 and tries to download all the web catalogs at once, the amount of data will be too large and it will take a long time to download, allowing efficient design of BIM models. Can not do it. As shown in the illustrated example, a first intermediate file 60 is sent from the design user terminal 10 to the web catalog server 20, and in this first intermediate file 60, a product data list of each manufacturer regarding one object to be currently set is provided. (an object data list that summarizes object data) and the design user terminal 10 receives the corresponding second intermediate file, thereby making it possible to efficiently design a BIM model.

Returning to FIG. 3, the first input/output unit 122 accepts the data transmitted and received by the first communication unit 120, outputs and displays it on a display device such as a liquid crystal display of the design user terminal 10, or responds to commands from the design user. Based on this, the BIM model is output and displayed on a display device.

The first storage unit 126 is installed with BUS-6 (manufactured by Kozo System Co., Ltd.), which is a highly functional integrated structural calculation software for RC/SRC/S buildings. Here, RC construction indicates a reinforced concrete construction, SRC construction indicates a steel reinforced concrete construction, and S construction indicates a steel frame construction. The design department 124 reads the high-performance integrated structural calculation software, creates a calculation model within the calculation software based on the BIM design model designed by the design designer, and calculates the various components that make up the calculation model. Enter the specification information and perform structural calculations. Since the calculation model created within the calculation software is not a BIM model, it is a non-BIM calculation model.

In the first storage unit 126, ST-Bridge (manufactured by Building SMART Japan, a general incorporated association) that connects structural calculation software and BIM software, and Autodesk Revit (registered trademark) (manufactured by Autodesk) as BIM software are installed. By activating these software in the design unit 124, a non-BIM calculation model is converted into a BIM calculation model.

Structural design staff can improve the BIM structural model by adding various components that were not necessary for the structural calculation to the BIM calculation model that has cleared the specified structural safety through structural calculation. design. A BIM model (BIM structural model) includes structural members such as beams and columns necessary for structural calculations of the building being designed, as well as non-structural components such as stairs, walls, ceilings, floors, doors, windows, and various piping.

A list of product data will be displayed. Then, when the person in charge of designing selects one piece of product data, the selected product data is stored in the first storage unit 126 as specification information of the object to be designed, and is linked to the object.

Then, when the product data is linked to the object, the object and its product data are automatically input into the design document created when designing the BIM model. Here, FIG. 8 is a diagram showing an example of a design document stored in the design user terminal.

In FIG. 8, product data information set for base materials and finishing materials is input as a design document for an object wall.

By repeating the same operations as described above for all the objects making up the BIM model, a design document in which each object and corresponding product data are input is created, and the BIM model is designed. In this way, products related to each object that constitutes a BIM model are organized into a data list, and when a product to be applied to the actual BIM model is selected from the data list, the design documents are automatically entered into the database. This makes it possible to efficiently import product data from manufacturers into a database in a BIM model.

[Design support method according to embodiment]
Next, with reference to FIG. 9, an example of the design support method according to the embodiment will be described. Here, FIG. 9 is a flowchart of an example of the design support method according to the embodiment.

First, a design user terminal 10 that designs a BIM model of a building sends an object data list containing object data of one or more manufacturers regarding objects that constitute a BIM model to a web catalog server 20 that stores a web catalog. 70 is executed (step S300).

As already explained using FIG. 4 and the like, the first intermediate file 60 clarifies the requested object and requests the Web catalog server 20 for product data regarding the requested object.

Next, the Web catalog server 20 executes an input creation process for creating a second intermediate file 80 formed by inputting the object data list to the received first intermediate file 60 (step S310).

The web catalog server 20 stores an object data list 70 that compiles data regarding products from various manufacturers for various objects, and the web catalog server 20 stores product data requested in the first intermediate file 60. Extract product data regarding the object, create a second intermediate file 80 in which the extracted product data list is input as the reply content to the request of the first intermediate file 60, and save the second intermediate file 80 to the design user terminal 10. Send. The second intermediate file 80 can be sent to the design user terminal 10 when the web catalog server 20 receives a command requesting transmission from the design user terminal 10, or when the second intermediate file 80 is created. There is a form in which the information is automatically transmitted to the design user terminal 10 when the information is received.

Next, in designing the BIM model of the building, the design user terminal 10 receives the second intermediate file 80, reads (part of) the object data list 70 input to the second intermediate file 80, A design process is executed in which object data (product data) selected from (part of) the object data list 70 is incorporated into a BIM model and designed (step S320).

By executing steps S300 to S320 described above for all objects that constitute the BIM model to be designed, a BIM model in which specification information such as product data is linked to each object is efficiently designed. be able to. Furthermore, when a BIM model is designed, a design document that summarizes each object and its specification information is automatically created. In the process of designing this BIM model, there is no need for the design person to directly input specification information into the design documents, making it possible to improve the efficiency of BIM model design, including the creation of design documents.
