Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings.

1 is a block diagram showing a schematic configuration of a construction specification generation system using BIM information according to an embodiment of the present invention.

The building construction specification generation system 1000 using the BIM information according to the present invention uses the BIM (Building Information Modeling) data indicating the property and digital modeling information for the facilities constituting the building, and results of virtual construction simulation, by module of the building A digital specification reflecting information on quotation, quantity, and construction period can be generated and provided to the user.

Specifically, the object approach detection apparatus 1 according to an embodiment of the present invention includes a simulation unit 100, a construction information generation unit 200, a specification generation unit 300, a matching unit 400, and a payment unit 500 ).

At this time, the building construction specification generation system 1000 using BIM information according to the present invention may be implemented in a fixed or fixed device. The device may be in the form of a server or an engine, and may be a device, an apparatus, a terminal, a user equipment (UE), a mobile station (MS), or a wireless device. , Handheld device, and other terms.

In addition, the building construction specification generation system 1000 using BIM information may be implemented by more components than the components shown in FIG. 1, and may be implemented by fewer components. Alternatively, the building construction specification generation system 1000 using BIM information includes at least two of a simulation unit 100, a construction information generation unit 200, a specification generation unit 300, a matching unit 400, and a payment unit 500. One component may be integrated into one component, and one component may perform a complex function. Hereinafter, the above-described components will be described in detail.

The simulation unit 100 may model a virtual building according to a user request using BIM data.

Specifically, the simulation unit 100 may model a virtual building desired by the user by using specific BIM data selected by the user from among BIM data for each facility previously stored. Accordingly, the user can create a virtual building for the building he or she wants to build by combining previously generated facilities, such as assembling blocks.

In this process, the simulation unit 100 generates each facility constituting a virtual building on the basis of BIM data in the form of a solid model in a three-dimensional virtual space, and combines the generated solid model-like facilities to create a three-dimensional virtual You can model a virtual building in space. In this regard, it will be described with reference to FIG. 2 together.

2 is a view for explaining a specific function of the simulation unit 100.

The simulation unit 100 may communicate with a user terminal possessed by a user who wishes to build a building and receive a selection signal for a type of facility desired by the user (21).

In this case, the simulation unit 100 may search the database unit of the device, and extract BIM data corresponding to a selection signal from among BIM data for each facility previously stored in the database unit (22).

Thereafter, the simulation unit 100 may analyze each extracted BIM data and convert the analyzed specific facility into a 3D virtual object implemented in the form of a solid model (23).

Specifically, in the simulation unit 100, different spatial modules according to the purpose of use, such as a master room, a bathroom, a living room, a multi-purpose room, and a terrace, may be configured and stored in detail. When receiving the BIM data for at least one spatial module selected from the user, the simulation unit 100 places each received BIM data in the corresponding spatial module or combines it with other neighboring BIM data to each spatial module selected by the user 3D virtual objects to be included in the model can be modeled.

Unlike solid-based GIS data, IFC data represented by BIM's standard format is configured based on parameters.

For example, in order to represent a rectangular parallelepiped such as a wall surface, conventional Geographic Information System (GIS) data directly stores three-dimensional coordinates of all corners constituting the rectangular parallelepiped and a triangular plane composed of them, whereas the BIM data is a wall surface. The 3D coordinates (geometric information) of both ends of the center line at the bottom of the line, the thickness of the line, and the height of the wall (property information) are stored.

Therefore, unlike GIS data, BIM data has a characteristic that it must be calculated every time based on the stored parameters in order to represent the 3D shape of the object on the screen.

In order to visualize the solid modeling-based object (BIM data) on the screen, a process of converting it into polygonal mesh data is required, and the simulation unit 100 performs this series of processes so that the user wishes The facility can be created as a three-dimensional object in the form of a solid model.

That is, the three-dimensional virtual object generated by the simulation unit 100 is a shape in which multiple polygonal planes (solids) are connected, and the size of the capacity for visualizing each facility can be determined according to the size of individual polygons. For example, if the size of the individual polygons becomes smaller, the facilities can be more accurately expressed, while the capacity for representing each facility is increased. In this case, the entire virtual building in which a plurality of facilities are combined is output as image information. The time to do so may be delayed.

Therefore, the simulation unit 100 needs to efficiently set the capacity of the modeling file for the virtual building in consideration of the service environment.

To this end, the simulation unit 100 uses a plurality of sub-solid models having different precisions for one facility (a three-dimensional object model) so that the file size of the modeling file for the virtual building can be varied according to the situation. Can be created (24).

Specifically, the simulation unit 100 may generate a first sub-solid model with reduced precision by increasing the size of individual polygons constituting the mesh model in the generated specific 3D solid model. In addition, the simulation unit 100 may reduce the size of individual triangles constituting the mesh model to generate a second sub-mesh model with improved precision.

In this way, the simulation unit 100 may generate and match sub-solid models having different precision for each 3D virtual object (facilities) generated.

Subsequently, the simulation unit 100 generates a 3D virtual object (depending on the construction schedule recorded in the digital specification generated by the specification creation unit 300 described later or the desired payment amount of the user received from the payment unit 400 described below ( According to the capacity of the modeling file representing the virtual building in which the facility) is combined, a modeling file in which the precision of a specific mesh model is varied (25) may be generated and transmitted to the user terminal (26). Details related to this will be described later.

The construction information generation unit 200 may generate construction information for actually constructing the virtual building based on each BIM data constituting the virtual building generated by the simulation unit 100.

Here, the construction information generated by the construction information generation unit 200 may include cost information, period information, and personnel information.

The cost information may be generated based on unit price information set for each facility, such as a pillar, a wall, a floor, a window, a roof, and an insulating material constituting a virtual building. The construction information generation unit 200 searches each BIM data for a facility, and each facility is composed of a certain material, and considering the size of the area (size, length, etc.), manufacturing the facility with a specific material Can calculate individual unit price. Thereafter, the construction information generation unit 200 may calculate cost information defined as a total amount required when constructing a virtual building by summing each unit price information.

The period information may include information on the time required to construct the virtual building generated by the simulation unit 100 step by step. To this end, the simulation unit 100 may perform a simulation process of sequentially combining a plurality of facilities selected from a user, and set the time required as period information.

At this time, the simulation unit 100 analyzes the generated construction schedule and extracts at least one facility or module to which current construction is to be performed among all facilities constituting the virtual building, and the extracted facility or module is set with relatively high precision. Convert to a sub-solid model with 1 precision, and other facilities and modules to a sub-solid model with a second precision lower than the first precision. Accordingly, the modeling file generated by the simulation unit 100 can express the facilities of the part currently being constructed in detail, and the facilities or modules that have already been constructed or have not yet been constructed can be expressed relatively briefly.

The specification generating unit 300 may generate a digital specification including a modeling file for a virtual building, construction information, and information about a selected construction company. That is, the digital specifications generated by the specification generation unit 300 include process simulation based on BIM data, quotation and quantity for each module, unit cost of labor and construction materials, capacity of modeling files, and prices for downloading modeling files, etc. All the information necessary for the actual construction of the building can be recorded.

The matching unit 400 may select any one construction company for actually constructing the virtual building based on the generated construction information.

Specifically, the construction history data previously received and stored by a plurality of construction companies may be previously stored in the database unit, and the matching unit 400 analyzes the previously stored construction history data to calculate the similarity with the virtual building, and calculates A construction company matching the construction history data having a similarity or higher than a preset threshold value may be classified as a construction candidate group, and the construction information may be transmitted to a terminal linked to a construction company included in the construction candidate group. The matching unit 400 may select a specific construction company based on the approval signal received from any one construction company terminal included in the construction candidate group.

The payment unit 500 may perform a payment process with a user terminal of a user who wants to receive the generated digital specifications.

At this time, the simulation unit 100 determines the size of the file size of the modeling file based on the desired payment amount information input from the user, and the modeling file in which the precision of the facility is dynamically varied to be equal to or less than the determined file size of the modeling file Can generate

As another example, the simulation unit 100 may generate modeling files having different precision for each module by reflecting information on a module of interest set by a user. More specifically, the simulation unit 100 determines the file capacity size of the modeling file based on the desired payment amount information input from the user, and based on the module information selected by the user, the selected module is a sub having a first precision. Convert to a solid model, and other modules not selected can be converted to a sub-solid model having a second precision lower than the first precision. That is, the simulation unit 100 expresses a specific module selected by the user precisely, while expressing briefly about a module that is relatively less interested, so that even if a modeling file having the same file capacity is generated, the user is set differently for each user The detailed structure of the space can generate a clearly expressed modeling file.

To this end, the building construction specification generation system 1000 using BIM data according to the present invention may be pre-installed with software (application) for performing each step constituting the construction construction specification generation method using BIM data described later. .
