Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0020] See also Figure 1 Embodiment 1 of the present invention provides a digital collaborative design method for subway station entrances and exits, comprising the following steps: S1. Constructing a collaborative design system for subway station entrances and exits, which includes collaborative design between architecture and structure at the conceptual design stage, collaborative design between architecture and structure at the preliminary design stage, and collaborative design between architecture and structure at the construction drawing design stage; S2. Based on the universal design platform Revit, a data model collaborative interaction strategy between the architectural and structural disciplines under the subway station entrance and exit collaborative design system is established; S3. Based on the collaborative interaction strategy of the data model between the architecture and structure disciplines, a subway station entrance and exit design tool is developed, wherein the development of the subway station entrance and exit design tool includes the selection of a development platform, specific development implementation, and design tool testing; S4. Define the functional components of the subway station entrance and exit design tool, which include creating a volume component, creating a model component, modifying and updating a model component, a structural slotting component, and a design drawing component.

[0021] In this embodiment, in step S1, during the collaborative design process of the architecture and structure professionals in the scheme design stage, the preliminary architectural scheme model is designed according to the station main interface information and the preliminary surrounding information, and the preliminary scheme model is completed by mutual input with the structural professionals; the architectural stability scheme model is in-depth designed according to the preliminary architectural scheme model, the station main interface information, and the detailed surrounding information; the structural stability scheme model is in-depth designed according to the station main interface information and the detailed surrounding information, and the architectural and structural professional designers mutually input and modify the scheme to complete the stability scheme model; During the collaborative design process between the architectural and structural professionals at the preliminary design stage, the architectural and structural professionals will deepen and coordinate modifications based on the stable solution model; During the collaborative design process between the architecture and structure professionals at the construction drawing design stage, the architecture and structure designers form a change model through coordinated modifications and further deepen it to form a construction drawing model; when no design changes occur, the architecture and structure designers directly form a construction drawing model through coordinated modifications and deepening.

[0022] See also Figure 2 Specifically, the subway station entrance and exit collaborative design system includes collaborative design of architecture and structure in the scheme design stage, preliminary design stage, and construction drawing design stage. The subway entrance and exit collaborative design system is a theoretical method for collaborative BIM model creation by entrance and exit structure and architectural professional designers in the entire digital design process.

[0023] Among them, in the scheme design stage, the architectural design professionals design the preliminary architectural scheme model according to the station main interface information and the preliminary information of the surrounding area, and at the same time, they provide input with the structural professionals to complete the preliminary scheme model. Subsequently, the architectural professionals carry out the in-depth design of the architectural stability scheme model according to the preliminary architectural scheme model, the station main interface information, and detailed surrounding information, such as survey / pipeline survey. The structural professionals carry out the in-depth design of the structural stability scheme model according to the station main interface information, detailed surrounding information, such as survey / pipeline survey, and the preliminary structural scheme model. During this period, the architectural and structural professional designers provide input and modify the scheme to complete the stability scheme model. In the preliminary design stage, the architectural and structural professionals deepen and coordinate the modification according to the stability scheme model. In the construction drawing design stage, when a design change occurs, the architectural and structural professional designers can form a change model through coordinated modification and continue to deepen to form a construction drawing model. When no design change occurs, the architectural and structural professional designers directly form a construction drawing model through coordinated modification and deepening.

[0024] In this embodiment, in step S2, based on the universal design platform Revit, a collaborative interaction strategy for the data model between the architecture profession and the structure profession under the collaborative design system for the subway station entrance and exit is established, including: S21. Architectural designers will create a preliminary volume model of the subway station entrance and exit in Revit for use in scheme design and rapid adjustment.

[0025] It can be understood that the data model collaborative interaction mode between disciplines provides business logic for the entire entrance and exit digital design method. The embodiment of the present invention establishes the data model collaborative interaction mode between disciplines based on the universal design platform Revit. The data model collaborative interaction mode can be divided into three aspects: the volume division of each section of the entrance and exit, the component elements in the BIM model, and the design results.

[0026] S22, the architectural professional designer establishes a building BIM model based on the preliminary volume model, and transmits the building BIM model to the structural professional designer through the platform collaboration function; The architecture major establishes a preliminary volume model to carry out entrance and exit scheme design and can quickly adjust the design scheme. The architecture major establishes a building BIM model based on the preliminary volume model and transmits it to the structure major through the platform collaboration function.

[0027] S23, the structural professional designer establishes a structural BIM model based on the preliminary volume model and the architectural BIM model, and maintains real-time data collaborative interaction with the architectural professional designer; The structural major creates and modifies the structural BIM model component elements based on the preliminary volume model and the architectural BIM model. During the process, the architectural and structural models can be transferred to each other to achieve collaborative interactive design.

[0028] S24. After designated rounds of collaborative design and optimization by architectural and structural designers, the design results of subway station entrances and exits are formed.

[0029] For details, see Figure 3 During the specific implementation of the collaborative interaction of data models between disciplines, the architectural designers divide the entrance and exit volumes into straight sections, turning sections, civil defense sections, lifting sections, and vertical elevators, thereby establishing an entrance and exit design plan and providing a benchmark for the BIM model design of the architectural and structural disciplines. At the same time, the architectural designers can quickly adjust the plan based on the above volumes. The architectural designers establish a building BIM model based on the above volumes, and its design component elements include surface layers, suspended ceilings, off-wall walls, building masonry walls, and the material information corresponding to the above design elements. The architectural profession passes the volume and the building BIM model to the structural profession, and the structural profession establishes a structural BIM model based on the above volume and the building BIM model. Its design component elements are divided into bottom plates, top plates, axillary angles, side walls, structural columns, off-wall grooves, and the material information corresponding to the above design elements. In this process, the architectural and structural disciplines can transfer and modify the models to each other to achieve collaborative interactive design, and finally complete the design BIM model, generate relevant drawings based on the model, and add relevant documents to form design results.

[0030] In this embodiment, in step S3, based on the collaborative interaction strategy of the data model between the architecture profession and the structure profession, the development of the subway station entrance and exit design tool includes: S31. Use the general design software Revit as the development platform, Visual Studio as the program compilation tool, and C# as the programming language; S32. Create a class library project in Visual Studio as the core code library of the design tool, reference the RevitAPI command space and interface definition files Revit API.dll and RevitAPIUI.DLL to achieve interaction with Revit; S33. Conduct application testing of the business architecture, architectural and structural collaborative design process for subway station entrance and exit design tools.

[0031] For details, see Figure 4The development of subway station entrance and exit design tools includes three aspects: development platform selection, specific development implementation, and design tool testing. The development platform is based on the general design software Revit, and the program compilation tool uses Visual Studio and C# language. In the specific development implementation, by creating a class library project and referencing the Revit API command space and interface definition files Revit API.dll and RevitAPIUI.DLL, secondly, a new IExternalCommand derived class is created, the Execute() method is overloaded, and related code is added. At the same time, a new IExternalApplication derived class is created, the OnStartup() method and the OnShutdown method are overloaded, and OnStartup and OnShutdown related code are added. After the code is written, a DLL (dynamic link library) file is generated, and the AddIn file is added in Revit. Open Revit for debugging. After successful debugging, the design tool plug-in is registered. Finally, the design tool is tested. Relevant professional designers conduct application tests on the design tool, mainly including its business architecture and the collaborative design process of architecture and structure. If the design function is not met, development modifications can be made to finally complete the development of the entrance and exit design tool.

[0032] In this embodiment, in step S4, a volume model is created according to the station main interface information, surrounding survey, and pipeline conditions through the volume component creation to provide a reference for the generation of the building BIM model and the structure BIM model; the volume model includes a straight section, a turning section, a civil air defense section, a lifting section, and a vertical elevator; The building BIM model is generated by the model creation component based on the volume model created by the volume creation component. The building BIM model generation includes creating surface layer, ceiling, off-wall wall, and building masonry wall model data. After the building BIM model is created, the volume model is retained; the structural BIM model is linked to the building BIM model, and the structural model data is generated by selecting the retained volume model on the basis of the building BIM model; The update objects of the model modification update component are the mass model, the building BIM model and the structural BIM model. When the design scheme changes, the building BIM model and the structural BIM model are linked to be changed by changing the mass model; The structural notching component is used to make notches on the wall of the structural model; the design drawing component is used to generate plane and section view drawings including those of architecture and structure.

[0033] Specifically, Figure 5 , Figure 6 As shown in the figure, the functional components of the subway station entrance and exit design tool include creating volume, creating models, updating models, structural slotting and designing exits. Figure 5 In the embodiment of the present invention, the functional component user interface adopts the Windows Presentation Foundation (WPF) user interface framework, selects to add a Windows form, and adds the required controls therein.

[0034] Specifically, Figure 7 As shown in the figure, in the creation of volume components, the architectural professional volume generates the entrance and exit scheme design, and creates a volume model based on the station main interface information, surrounding survey, and pipeline conditions to provide a benchmark for the generation of architectural and structural BIM models. The volume model includes straight sections, turning sections, civil defense sections, lifting sections, and vertical elevators. This division and design logic conform to the design habits of subway station designers and facilitates the design of station entrance and exit schemes.

[0035] Specifically, Figure 8 As shown in the figure, in the creation model component, the building BIM model is generated based on the mass model, and the surface layer, ceiling, wall, and building masonry wall model data are created. After the creation is completed, the mass model is retained. Fig. 9 As shown in the figure, the structural BIM model is linked to the architectural BIM model. The structural designer generates the structural model data by selecting the retained volume model based on the architectural model. After linking, the architectural model and volume model are identified through the copy monitoring function in the Revit software. The structural model is generated in sequence according to the straight segment, turning segment, civil air defense segment, lifting segment, and vertical elevator volume model. The model data includes the bottom plate, top plate, axillary angle, side wall, structural column, wall groove and its corresponding material information. Fig.10 As shown, when the end wall is generated, the end wall structure is generated according to the intersection of different volumes. There are two modes: segment generation and full generation. Segment generation is to generate a single end wall based on the volume connection of the straight segment, turning segment, civil air defense segment, and lifting segment. Full generation is to uniformly generate the end wall at all volume intersections, and the end wall thickness and material are added according to the design requirements.

[0036] Specifically, Fig.11 As shown in the figure, the model change update component updates the mass model, building BIM model and structural BIM model. When the design plan changes, the building and structural BIM models are linked by changing the mass model. There are two ways to change: generate by segment and generate all. The segment generation is to select and update the model according to the volume changes of the straight segment, turning segment, civil defense segment and lifting segment. The all generation is to update all the models on all the volumes.

[0037] like Fig.12 As shown, the structural slotting component is used to slot on the wall of the structural model, and the slotting information includes height, width, depth, height from the bottom of the surface layer, plane distance from the starting surface, and exit direction.

[0038] like Fig.13 As shown, the designed drawing components include plan and section perspective drawings of architecture and structure, and dimension annotations are generated. The drawings also include drawing name, drawing frame, drawing number, and drawing size information.
