[0070] See also Figure 1 Embodiment 1 of the present invention provides a multi-dimensional digital design method for urban rail transit engineering, comprising the following steps:

[0071] S1. Construct a multi-dimensional digital design system, wherein the dimensions of the multi-dimensional digital design system include a time dimension, a personnel dimension, a quality dimension, and an intelligent operation operator;

[0072] S2. Constructing a collaborative design platform according to the multi-dimensional digital design system, wherein the network architecture of the collaborative design platform includes a basic support layer, a core data layer, an application support layer, an application layer and an interactive service layer;

[0073] S3, performing BIM model collaborative design according to the collaborative design platform, wherein the BIM model collaborative design includes a work set central file collaborative mode and a link mode, wherein the work set central file collaborative mode allows design members of the same professional team to access and edit the same central file; and the link mode allows design members of different professional teams to collaborate;

[0074] S4. Add information data to the BIM model, wherein the information data includes geometric information and attribute information of specified model components, so that the BIM model complies with the full life cycle application of intelligent construction.

[0075] See also Figure 2 In this embodiment, it should be noted that, in step S1, a multi-dimensional digital design system for urban rail transit engineering can be built based on actual engineering experience and literature research. Each dimension is divided into a time dimension, a personnel dimension, a quality dimension, and an intelligent operation operator. The multi-dimensional digital design system has a unified paradigm, and the unified paradigm of the multi-dimensional digital design system is:

[0076]

[0077] In the formula, For the digital design system results, is the time dimension, They are scheme design, preliminary design and construction drawing design. For the personnel dimension, They are survey, construction, structure, electromechanical, and system professional designers. is the quality dimension, They are geometric information, object attributes, and design logic. It is an intelligent operation operator.

[0078] In this embodiment, in step S2, the basic support layer includes hardware resources, software resources and network environment, and the basic support layer provides computer hardware and software resources and network environment;

[0079] The core data layer includes a user database, a design resource library, a component database and a model database;

[0080] The application support layer includes a workflow engine, Revit API, system log, report engine and lightweight engine;

[0081] The application layer includes project space, personnel management, design funding, design stage division, quality audit tool and intelligent design tool. The personnel management and design funding correspond to the personnel dimension, the design stage division corresponds to the time dimension, the quality audit tool corresponds to the quality dimension, and the intelligent design tool corresponds to the intelligent operation operator.

[0082] The interactive service layer includes a client and a browser.

[0083] Specifically, Figure 3 As shown in the figure, the network architecture of the collaborative design platform includes the basic support layer, the core data layer, the application support layer, the application layer and the interactive service layer. The basic support layer includes hardware resources, software resources and network environment. The basic support layer is used to provide computer hardware and software resources and network environment. It belongs to the computer technology support of the collaborative design platform and is the basic condition to ensure the operation of the collaborative design platform. The core data layer includes the user database, the design resource library, the component database and the model database. This layer includes all the basic data of the platform. The application support layer includes the workflow engine, Revit API, system log, report engine and lightweight engine. This layer provides support services for this architecture and is used to integrate data and transmit it in the form of data streams. The application layer includes the functions related to the collaborative design platform, namely project space, personnel management, design funding, design stage division, quality review tool and intelligent design tool. The personnel management and design funding functions in this layer correspond to the personnel dimension in the multi-dimensional digital design system of urban rail transit projects, the design stage division function corresponds to the time dimension, the quality review tool corresponds to the quality dimension, and the intelligent design tool corresponds to the intelligent operation operator. The interactive service layer includes the client and browser. Designers and project managers of relevant professions can perform digital design operations and project management work on the client and browser.

[0084] like Figure 4 As shown in the figure, the main interface of the collaborative design platform has the functions of creating project space and publishing project announcements. Project managers can create projects and add project information. Each project can add scheme design, preliminary design, and construction drawing design stages, and maintain the urban rail transit projects involved. Each project can be displayed in the project space. When relevant matters need to be released for this project, an announcement can be published for design participants and managers to review.

[0085] like Figure 5As shown in the figure, when using this collaborative design for personnel and model management, it can be divided into architecture, structure, HVAC, water supply and drainage, power supply and other specialties according to the design characteristics of urban rail transit projects. Each professional has the authority to conduct digital design on this platform. The overall design unit personnel and the owner as managers have relevant project management functions such as model viewing, professional designer login status viewing and model update status viewing on this platform to achieve design quality and progress control.

[0086] like Figure 6 As shown, on this collaborative design platform, each designer can transfer design model data to upstream and downstream professionals to provide funding, and can also attach a brief description to facilitate project communication. The funding conditions can be displayed in the project matters to facilitate the review and communication of relevant designers. This measure can effectively realize the rapid and efficient transmission of design information and the smooth flow of design data.

[0087] like Figure 7 As shown in the figure, various intelligent design tools for urban rail transit projects can be integrated into the collaborative design platform for joint use, and can also be used independently of the collaborative design platform according to the needs of different projects.

[0088] In this embodiment, in step S3, in the work set center file collaboration mode, different work sets are assigned to design members of the same professional team according to specific duties and responsibilities, and corresponding permissions are set;

[0089] In the linking mode, based on a BIM model, the mapping relationships of one or more BIM models are linked together, and the model data between disciplines are updated synchronously in real time.

[0090] Specifically, professionals in urban rail transit projects conduct collaborative design of BIM models in the collaborative design platform. Figure 8 As shown, collaborative design among professionals means that each professional designer carries out professional design according to the interface condition model, and also needs to provide the design model of the profession to ensure smooth flow of design information. The interface condition model is the relevant design model that needs to be referenced for the profession. For example, the model referenced by the architectural profession is the structure and electromechanical professional model, and the model referenced by the structural profession is the architecture, survey, and electromechanical professional model. The collaborative design work within the same profession of urban rail transit adopts the work set mode. In the work set central file mode, the design data within the urban rail transit profession can be integrated into the same central file for real-time data interaction and timely discovery of problems in the design work.

[0091] Among them, the platform calls the general design software Revit when conducting collaborative design, and the collaborative design work within the same discipline of urban rail transit adopts the workset mode in the design software Revit. In the workset central file collaborative mode, team design members in the same discipline can access and edit the same central file, but each member is assigned a different workset according to specific duties and responsibilities, and the corresponding permissions are set to ensure that each team member can only edit the parts related to his or her duties, thereby avoiding unnecessary interference and errors. This ensures that each person can work independently while sharing and updating design information.

[0092] like Figure 8 As shown, the collaboration between disciplines adopts the link mode. The link mode refers to a working mode that links the mapping relationship of one or more BIM models on the basis of a BIM model. The model data of each discipline can also be updated synchronously in real time. Specifically, the collaboration between different disciplines in urban rail transit adopts the link mode in the design software Revit. The link mode refers to a working mode that links the mapping relationship of one or more BIM models on the basis of a BIM model. Model linking is achieved through the "Manage Links" option in the Revit "Manage Project" panel. When the linked model is changed, the link will be automatically updated in real time. The copy and monitor functions in Revit allow team members to monitor changes to elements or models and receive notifications, which ensures that all team members are aware of the latest design changes, thereby avoiding errors and rework caused by information asymmetry.

[0093] like Fig. 9 As shown, in the collaborative design platform, relevant intelligent design tools can be used to generate BIM models, and the architecture profession can use the intelligent design tools for the main building of the station to generate station scheme models. During the design process, the station is divided into three major parts: the small end, the public area, and the large end. The small end includes the ventilation room, air duct, lighting distribution room, and wastewater pump room. The public area includes the station hall and platform. The large end includes management rooms, weak current rooms, ventilation rooms, toilets, high and low voltage switch rooms, and rectifier transformer rooms. By generating the above room volume models, the room layout is freely arranged, which is convenient for architectural professional designers to design station schemes.

[0094] like Fig.10 As shown, relevant intelligent design tools can be used to generate BIM models in the collaborative design platform. The architectural profession can create a volume model to provide a benchmark for the generation of the structural model. The volume model includes straight segments, turning segments, civil defense segments, lifting segments, and vertical elevators. This division and design logic are in line with the design habits of subway station designers and are convenient for the design of station entrances and exits. Structural professionals design corresponding structural components based on the above volume model to create a structural BIM model.

[0095] like Fig.11 As shown, in the collaborative design platform, relevant intelligent design tools can be used to generate BIM models. The tool can automatically read the interval structure line data to enable structural professionals to automatically generate the interval structure function by designing the cross section, including the interval shield structure and the dark excavation structure. The interval shield structure model includes standard ring capping blocks, standard ring adjacent blocks, standard ring standard blocks, left-turn ring capping blocks, left-turn ring adjacent blocks, left-turn ring standard blocks, right-turn ring capping blocks, right-turn ring adjacent blocks, and right-turn ring standard blocks. The dark excavation structure model includes initial support, secondary lining, support anchor rods, and advanced pipe sheds.

[0096] In this embodiment, in step S4, the geometric information includes information on the size, positioning and mutual relationship of model elements;

[0097] The attribute information includes physical information and management information. The physical information includes elastic modulus, Poisson's ratio and material of the model component. The management information includes supplier, maintenance time and installation unit.

[0098] Specifically, in the BIM model, information data is added to the BIM model by adding parameters to the model components. The specific information data includes the geometric information and attribute information of the relevant model components. The geometric information specifically refers to the size, positioning and relationship information of the model elements. The attribute information mainly includes physical information and management information. Among them, physical information refers to the elastic modulus, Poisson's ratio, material, etc. of the component, so as to analyze and optimize the structural mechanical properties, building space layout, etc. The management data mainly includes suppliers, maintenance time, installation units, etc. Taking the main building design of the subway station as an example, the scheme stage should include the exterior wall, the geometric information is the size and spatial positioning, and the non-geometric information is the material and specifications; the preliminary design stage should include doors, windows, walls, stairs, and improve the geometric information and attribute information of the relevant components; in the construction drawing design stage, the reserved holes of the middle plate are added to the preliminary design stage, and the fire protection requirements information should be supplemented to facilitate the subsequent application of the entire process of intelligent construction.

[0099] In this embodiment, the method further includes: step S5: using a quality audit tool to audit the BIM model; the quality audit tool includes a model preparation component, a compliance check component, and a review result output component;

[0100] Checking the geometric information and object attribute information of the data model through the model preparation component, so that the data model carries the objects, attributes and names required for rule checking;

[0101] Determining whether the design model complies with the requirements of the specified design specification by the compliance checking component, and identifying the design model components that do not comply with the requirements of the specified design specification;

[0102] When the inspection is completed through the review result output component, the results are summarized and an inspection report is issued. The inspection result of each rule is displayed in the inspection report using a graphical interface, and a reference to the original rule is provided in the inspection report.

[0103] Specifically, Figure 12-13 As shown in the figure, the intelligent review tool corresponds to the quality dimension. The intelligent review tool plays a role in ensuring the quality of the design BIM model after the design is completed in the entire design method. The intelligent review tool is integrated in the collaborative design platform mentioned above. The intelligent review tool includes a model preparation component, a compliance check component, and a review result component.

[0104] Among them, the model preparation component is used to check the geometric information and object attribute information of the data model to ensure that the model carries the objects, attributes, and names required for rule checking, so as to facilitate the extraction of necessary data from the design model results for compliance checking; the compliance check component is used to determine whether the design model meets the requirements of relevant design specifications and identify the model components that do not meet the rule requirements. This component is mainly responsible for reviewing rule formulation and design logic judgment; the review result output component is used to summarize the results and issue an inspection report after the inspection is completed. The inspection report uses a graphical interface to display the inspection results of each rule, which is convenient for users to understand more intuitively. At the same time, a reference to the original rule is provided in the report, so that users can clearly know which specifications the design results violate and how to make necessary design adjustments based on these specifications.

[0105] Among them, the relationship and data flow between the components of the intelligent audit tool are as follows: when the design model is completed, it enters the model preparation component to form the model data, and then enters the compliance check component. In the compliance check component, the quality audit rules are first formed, and the design logic check is performed in combination with the model data, and finally the audit result is output through the audit result component. For the model preparation component, in the establishment of the model at each stage of the design, there are inevitably problems such as component geometric size errors, component naming, component missing, and attribute information missing. The intelligent audit tool incorporates it into the model preparation stage, and returns those that do not meet this requirement to the relevant designer for modification. Through the geometric information and object attribute information check, it is ensured that the model carries the objects, attributes, and names required for rule checking, so as to facilitate the extraction of necessary data from the design model results for compliance review. For the compliance check component, the quality audit rules are first formulated. There is a lot of relevant knowledge about the professional design logic of urban rail transit in the subway design specifications and expert experience. This content is usually expressed in the form of written text, tables, and possibly equations. First-order predicate logic is used as a formal method to map the rules defined in natural language to a machine-executable form.

[0106] Among them, two methods are used to formulate audit rules. The first is to use computer language coding, use parameterization and branches to compile specifications and expert knowledge into computer programs, and the other method is parameter tables, which write parameters, branches and other logical structures to define a class of rules, which are instantiated by parameter tables. After the audit rules are established, the model data of the model preparation component will be used for design logic inspection. This process establishes an interactive relationship between the audit rules and the model data, realizes rule reasoning, and then determines whether the model meets the requirements of the relevant design specifications, and identifies the model components that do not meet the requirements of the rules. The review result component is that when the inspection is completed, the results need to be summarized and an inspection report is issued. When the model uses a graphical interface to display the inspection results of each rule in the inspection report, it is convenient for users to understand more intuitively. At the same time, a reference to the original rule is provided in the report, so that users can clearly know which specifications the design results violate, and how to make necessary design adjustments according to these specifications.
