[0002] BIM (Building Information Modeling) technology can achieve real-time management and control of the entire construction cycle by establishing a virtual building model.

The application of BIM technology enables engineering projects to effectively establish resource plans, control financial risks, save energy, save costs, reduce pollution and improve efficiency in the design, construction and operation and maintenance stages.

[0003] In current hydropower projects, BIM technology has gradually become a core tool for project management and implementation. Its application is not limited to the design and construction stages, but also covers the completion and operation and maintenance stages; that is, it can be applied to the entire life cycle of hydropower projects.

[0041] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0042] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application, and thus the drawings only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated.

[0043] The following will describe in detail the digital delivery method of hydropower projects based on the BIM model provided in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application.

[0044] See also Figure 1 and Figure 2 , respectively showing a flow chart of a method for digital delivery of a hydropower project based on a BIM model in one embodiment of the present application and a schematic diagram of implementation steps of a method for digital delivery of a hydropower project based on a BIM model in one embodiment of the present application. Figure 1 and Figure 2 As shown, this embodiment provides a digital delivery method for hydropower projects based on a BIM model.

[0045] The BIM model-based hydropower project digital delivery method specifically includes the following steps:

[0046] S1, constructing a hydropower engineering model data standard. The hydropower engineering model data standard includes but is not limited to: naming specifications, attribute definitions, geometric accuracy requirements, data format requirements, etc. of engineering components.

[0047] In this embodiment, a set of unified modeling data standards is first formulated, namely: hydropower engineering model data standards. This standard covers but is not limited to the following contents: naming specifications of engineering components, attribute definitions, model units, model unit geometric accuracy requirements, data format requirements, etc. Through standardized data specifications, the consistency and operability of model data are ensured.

[0048] Specifically, the naming conventions of engineering components in the hydropower engineering model data standard mainly include: file naming and component naming, etc.

[0049] For example, in order to facilitate model reviewers or users to intuitively read model information (such as model affiliation, profession, implementer, creation time, etc.), file names should be concise and easy to identify. The naming format is as follows: <project abbreviation><phase><professional code><partition>-<…>-<part / system>[model description].

[0050] Similarly, for the convenience of management and forming a project-level family library or component library, the naming of model components should be unified. The naming principles are as follows: component category (optional) - component type (required) - component name (optional) - material (required) - component size (required). The component name should be consistent with the design data.

[0051] It should be noted that specific naming conventions can be formulated according to user needs.

[0052] The attribute definition includes but is not limited to: text segment name, encoding, data type, data format, measurement unit, value range, constraint conditions, etc.

[0053] Specifically, the model unit attribute information is reflected by selecting an appropriate information depth and classifying the attributes. Attributes include but are not limited to: Chinese field name, encoding, data type, data format, unit of measurement, value range, constraints, etc. At the time of delivery, at least the Chinese field name and unit of measurement should be included. The attribute value should comply with the principle of uniqueness, that is, the attribute value and the attribute should correspond one-to-one, and the attribute value should be unique in a single application scenario. The attribute value should also comply with the principle of consistency, that is: attributes of the same type should be consistent in format and precision.

[0054] In this embodiment, the model unit classification and selection of appropriate model precision are determined according to the delivery depth and the form of the deliverable. The model unit should include geometric information and geometric expression accuracy, attribute information and information depth, and data sources of attribute values.

[0055] Specifically, the model unit includes: project-level model unit, function-level model unit, component-level model unit and part-level model unit. The content is as follows:

[0056] (1) Project-level model unit: such as hub layout diagram, which carries project, sub-project or local engineering information.

[0057] (2) Functional level model unit: such as power generation building model, which carries complete functional system or space information.

[0058] (3) Component-level model unit: For example, a turbine model carries the information of a single component.

[0059] (4) Part-level model unit: For example, a turbine blade model carries the component parts or installation parts information of a component.

[0060] The geometric accuracy requirements for model units include: model fineness in the survey and design pre-feasibility study stage, model fineness in the survey and design feasibility study stage, model fineness in the survey and design construction drawing stage, and model fineness in the construction management stage and operation and maintenance stage.

[0061] Specifically, the refinement requirements of the model unit are as follows:

[0062] (1) The model precision of the survey, design and pre-feasibility study stage shall not be less than LOD1.0, and the smallest model unit shall be the project-level model unit;

[0063] (2) The model precision of the survey, design and feasibility study stage shall not be less than LOD2.0, and the minimum model unit shall be the functional level model unit;

[0064] (3) The model precision of the survey, design and construction drawing stage shall not be less than LOD3.0, and the smallest model unit shall be the component-level model unit;

[0065] (4) The model resolution during the construction management and operation and maintenance phases shall not be less than LOD4.0, and the smallest model unit shall be the part-level model unit.

[0066] S2, constructing a hydropower project BIM model based on the hydropower project model data standard. Figure 3 , which is a flow chart of S2 in the BIM model-based hydropower project digital delivery method described in this application. Figure 3 As shown, S2 comprises the following steps:

[0067] In this embodiment, building components are modeled and their attributes are defined based on the hydropower engineering model data standard to obtain a hydropower engineering BIM model.

[0068] Specifically, the BIM model is constructed on the basis of establishing data standards. Standardized data specifications are used to model and define the properties of building components to ensure the integrity and accuracy of model data. The constructed model must meet the accuracy requirements of delivery and contain all necessary attribute data. In view of the characteristics of various disciplines in hydropower engineering, we mainly use Bentley platform software and supplement it with AutoDesk platform software to complete the modeling.

[0069] S21. Based on the needs of different majors, select the modeling tools corresponding to each major.

[0070] In this embodiment, in order to meet the needs of various professions, suitable modeling software is selected for modeling.

[0071] For example, Bentley software can be used in hydraulic engineering, HVAC, water supply and drainage, water machine, electrical engineering, and architecture. Metal structure can use the AutoDesk platform and import it into the Bentley platform through the intermediate format .sat. At the same time, all modeling work is carried out on the 3D collaborative management platform to ensure effective coordination among various disciplines and orderly interaction of data.

[0072] S22, customize the workspace according to the characteristics of the hydropower project and the needs of different professions, and deploy it. The workspace includes: any one or more combinations of layers, category styles, line types and line widths, colors, display styles, and component libraries.

[0073] In this embodiment, the workspace and deployment are customized. According to the characteristics of hydropower projects and the needs of different disciplines, a project-level workspace is formulated. The workspace not only specifies the layers, category styles, line types and line widths, colors and display styles, but also contains a library of commonly used components to ensure that each discipline is modeled under a unified standard.

[0074] S23, selection of modeling base point.

[0075] In this embodiment, the positioning benchmark of the unified model is determined to ensure the consistency and accuracy of each professional model. For some buildings that cannot be positioned using the plant axis grid (such as tailwater channels, traffic tunnels, drainage corridors, arch dams, outlet shafts, etc.), a control point positioning method using absolute positions as control points is used.

[0076] S24, select key areas for refined modeling.

[0077] In this embodiment, due to the wide scope and rich content of hydropower projects, different areas have different requirements for the geometric expression accuracy and attribute depth of the model. Therefore, according to actual application needs, key areas are selected for refined modeling to ensure the practicality and accuracy of the model.

[0078] S25, modeling is performed on a three-dimensional collaborative management platform to obtain a BIM model of the hydropower project.

[0079] In this embodiment, modeling, subassembly and final assembly are performed on the three-dimensional collaborative management platform. Through the collaborative work function of the platform, each discipline can share model data in real time to improve work efficiency and collaborative effect.

[0080] S3, performing analysis based on the hydropower project BIM model to obtain a analyzed hydropower project BIM model. Figure 4 and Figure 5 , respectively showing the process diagram of S3 in the method for digital delivery of hydropower projects based on BIM model described in this application and the schematic diagram of digital delivery of hydropower projects BIM model in one embodiment of the method for digital delivery of hydropower projects based on BIM model described in this application. Figure 4 and Figure 5 As shown, S3 comprises the following steps:

[0081] S31, parsing the hydropower project BIM model, and importing the parsed data into a digital delivery platform; the parsed data adopts structured data.

[0082] In this embodiment, the hydropower project BIM model is lightweight processed to extract structured data; the lightweight processing includes: geometric information extraction and attribute information extraction.

[0083] The geometric information extraction is to perform geometric data serialization processing on different types of geometric objects through a specific interface, and then output the geometric data by calling a function.

[0084] The attribute information extraction is to obtain the attribute library defined in the model file, then traverse the attribute groups and attribute items in each attribute library, and search for the value corresponding to each attribute field in the hydropower engineering BIM model.

[0085] Specifically, on the digital delivery platform, the BIM model will be stored in the form of structured data after lightweight processing. The core of this process is the extraction and optimization of geometric and attribute data to ensure that the necessary key information is retained while reducing the complexity and data volume of the model. For example, for the dgn format model file output by the Bentley series software, the data parsing tool is written based on the VC++ language and uses the modeling software development kit officially provided by Bentley and some special undisclosed model information extraction API (Application Programming Interface) interfaces.

[0086] The official API interface provides general data interfaces such as model geometry and attribute extraction, but the parsed model may lose materials and complex geometric shapes (such as complex surfaces and some Boolean shapes). To make up for these deficiencies, the unpublished API interface provides a variety of development kit files that can extract information on different model materials and complex geometric shapes.

[0087] Through the API interface of the modeling software, the complete geometry, material and attribute information of the model can be accessed. The next step is to customize the structured description of this data. For example, for geometric information, we process 3D entities, meshes and intelligent entities differently and output them into the required data structure; for materials, we distinguish between opaque, translucent, reflective / non-reflective and other material properties; for attributes, we process different attributes such as geometric feature information, spatial information and custom information differently.

[0088] Specifically, the extraction of geometric information mainly uses the IElementGraphicsProcessor interface in the Bentley SDK. Users need to implement the geometric data serialization method for different types of geometric objects (such as SolidPrimitive, Body, Surface, Curve, etc.) in this interface. Then, the geometric data is output according to the previously defined serialization method by calling the Process function in the ElementGraphicsOutput element output class.

[0089] Similarly, there are two methods for extracting attribute information: one is to use the EC Class method, because all element data in the DGN model are defined as EC Schema at the bottom layer, and all element attributes can be accessed. The other is to use the ItemLibrary method, first obtain the attribute library defined in the model file, then traverse the attribute groups and attribute items in each attribute library, and find the value corresponding to each attribute field in the model element. The ItemLibrary method is preferred because the attributes obtained by this method are consistent with the display in the software and are clearer. If more in-depth component data is required, use the EC method to traverse the underlying data of the model.

[0090] After the above processing, the model data is efficiently parsed and optimized to ensure that the data delivered to the digital delivery platform is complete and accurate, providing a reliable data foundation for subsequent engineering management and application.

[0091] It should be noted that the Process function is an officially unopened API and needs to be manually added to the header file of the development kit.

[0092] S32, delivering the objects and attributes in the hydropower project BIM model to a digital delivery platform.

[0093] Through step S31, the KV (Key-Value) set of each model component can be obtained. The system can configure the asset code (UUID) to aggregate the attributes and return it in the form of a list of UUID (Universally Unique Identifier) ​​and attribute key-value pairs.

[0094] In this embodiment, attribute acquisition is performed, that is, the attribute key value set of each model component is extracted from the hydropower engineering BIM model, wherein the attributes include: size, material, position and other related parameters.

[0095] Specifically, first, extract the attribute KV value set of each component from the BIM model. These attributes cover various information of the component, such as size, material, location, etc. The extracted attributes are not only the basic information of the component, but also its association and other relevant parameters in the entire building information model. This step ensures that all information of each component is accurately captured and recorded.

[0096] In this embodiment, asset aggregation is then performed, that is, through system configuration, the corresponding asset codes and attributes are aggregated to obtain a list of asset code and attribute key-value pairs.

[0097] Specifically, the system aggregates the corresponding asset code (UUID) and attributes through configuration. In other words, the system classifies and organizes the attributes of different components by UUID according to predefined rules. In this way, each component can be classified according to UUID, and a structured data set containing a list of UUID and attribute key-value pairs is returned. The purpose of this step is to systematize and standardize the scattered attribute data.

[0098] In this embodiment, the object is created again, that is, the asset code set is traversed and a new object is created for each asset code.

[0099] Specifically, the UUID collection is traversed, and a new object is created for each UUID according to the class code identification number (Key) configured by the system. This new object will belong to the class corresponding to the Key. Each class code identification number corresponds to a specific component category, which ensures that each component is correctly classified and instantiated as a specific type of object. This process not only realizes the structuring of data, but also lays the foundation for subsequent attribute allocation and data management.

[0100] In this embodiment, attributes are assigned to the new object.

[0101] Specifically, other keys are assigned as properties of the object. If a key has a corresponding value, the value is directly assigned to the property of the object; if there is no value, the property is set to null. In this way, the system can flexibly handle the incompleteness of different component properties to ensure the accuracy and completeness of data delivery. In this process, if necessary, default values ​​can be set or handled through other rules.

[0102] In this embodiment, the new object and the attributes after the attribute allocation are delivered to the digital delivery platform.

[0103] Specifically, ultimately, through the UI (User Interface), users can view and edit these properties to ensure that all objects and properties are correctly delivered to the digital platform. The UI provides a friendly interactive method that enables users to easily browse, modify and manage various properties in the BIM model. Through the UI, users can not only verify the attribute data automatically generated by the system, but also adjust and optimize it according to actual needs.

[0104] S33, delivering the drawings and documents in the hydropower project BIM model to the digital delivery platform.

[0105] Step S31 can obtain the attribute key value (KV) set of each model component. According to the drawing identification code and document identification code (Key) configured by the system, the system will download relevant drawings and documents from different systems according to the URL (Uniform Resource Locator) address in the corresponding value, and store them on the digital delivery platform. Subsequently, users can edit the attributes of these drawings and documents and preview the files through the platform.

[0106] In this embodiment, the attribute key value set of the model component in the hydropower project BIM model is configured to obtain a drawing identification code and a document identification code; address resolution is performed based on the drawing identification code and the document identification code to obtain a URL address containing the target file; based on the URL address, the required downloaded images and documents are obtained and stored in the digital delivery platform.

[0107] Specifically, first, configure the identification code. The system identifies and locates the drawings and documents to be downloaded based on the pre-configured drawing identification code and document identification code (Key). These identification codes are the system's unique identifiers for different types of files, ensuring that the corresponding files can be accurately found and processed.

[0108] Then, perform URL address resolution: the system reads the value corresponding to the identification code from the configuration, which contains the URL address of the target file. This URL address points to drawings and document resources in different systems, which may be the storage path of the internal system or the access link of the external system.

[0109] Next, download and store the files. The system automatically downloads the corresponding drawings and documents from different systems by parsing the URL address. This step involves cross-system file acquisition operations to ensure that all required files can be successfully downloaded locally. After the download is complete, the system stores these drawings and documents in the digital delivery platform. During the storage process, the system will classify and archive the files to ensure that the files are clearly organized and easy to manage on the platform.

[0110] Then, edit the properties. After storage is complete, users can edit the properties of drawings and documents through the digital delivery platform. These properties may include detailed information such as file name, creation date, author, version number, etc. Users can add, modify or delete these properties according to actual needs.

[0111] Finally, you can preview the file. File preview: The digital delivery platform provides a file preview function, which allows users to view the content of drawings and documents directly on the platform without downloading them locally. This function greatly improves the efficiency of file review and enables users to quickly browse and find the required information.

[0112] S34, delivering the coding association relationship in the hydropower project BIM model to the digital delivery platform.

[0113] In this embodiment, the attribute key value (KV) set of each model component can be obtained through step S31. The system manages these key value sets according to the configured business system identification code (Key). Based on the value corresponding to the identification code (Key), the system can effectively manage the corresponding object. Based on this mapping relationship, the extended information of the business system can be easily found later. This method not only improves the accuracy of system management, but also simplifies the retrieval and processing process of information.

[0114] S35, delivering the engineering breakdown structure automatically generated based on the object to the digital delivery platform.

[0115] The delivery of object data has been completed on the digital delivery platform through step S32. A tree of engineering decomposition structure can be generated for the object coding rules. The hydropower engineering object coding consists of a general coding combination and a subclass coding. The general coding combination is used to identify the plant and specialty to which the element belongs, and the subclass coding is used to classify the elements of the asset into three categories: civil engineering, electromechanical equipment, and space.

[0116] In this embodiment, the hydropower project analysis is performed according to the rules of object coding, a hydropower project decomposition structure tree is generated, and the structure is delivered to the digital delivery platform.

[0117] Specifically, the object code includes: a code combination and a subclass code. The code combination includes a plant code and an asset classification code, which is used to identify the plant and specialty to which the element belongs; the subclass code is used to classify the asset elements into three categories: civil engineering, electromechanical equipment, and space for identification.

[0118] The subclass codes include: first class objects, second class objects and third class objects.

[0119] in,

[0150] The following will describe in detail the BIM model-based digital delivery system for hydropower projects provided in this embodiment with reference to the diagrams.

[0151] This embodiment provides a digital delivery system for hydropower projects based on a BIM model.

[0152] See also Figure 7 , which is a schematic diagram of the principle structure of a hydropower project digital delivery system based on a BIM model described in this application in one embodiment. Figure 7 As shown, the BIM model-based digital delivery system for hydropower projects includes: a data standard construction module 71, a model construction module 72, a digital delivery module 73, and a display module 74.

[0153] The data standard construction module 71 is used to construct the hydropower engineering model data standard. The hydropower engineering model data standard includes but is not limited to: naming specifications, attribute definitions, geometric accuracy requirements, data format requirements, etc. of engineering components.

[0154] In this embodiment, a set of unified modeling data standards is first formulated, namely: hydropower engineering model data standards. This standard covers but is not limited to the following contents: naming specifications of engineering components, attribute definitions, model units, model unit geometric accuracy requirements, data format requirements, etc. Through standardized data specifications, the consistency and operability of model data are ensured.

[0155] Specifically, the naming specification of engineering components in the hydropower engineering model data standard mainly includes: file naming and component naming, etc. The specific naming specification can be formulated according to user needs.

[0156] The attribute definition includes but is not limited to: text segment name, encoding, data type, data format, measurement unit, value range, constraint conditions, etc.

[0157] Specifically, the model unit attribute information is reflected by selecting an appropriate information depth and classifying the attributes. Attributes include but are not limited to: Chinese field name, encoding, data type, data format, unit of measurement, value range, constraints, etc. At the time of delivery, at least the Chinese field name and unit of measurement should be included. The attribute value should comply with the principle of uniqueness, that is, the attribute value and the attribute should correspond one-to-one, and the attribute value should be unique in a single application scenario. The attribute value should also comply with the principle of consistency, that is: attributes of the same type should be consistent in format and precision.

[0158] In this embodiment, the model unit classification and selection of appropriate model precision are determined according to the delivery depth and the form of the deliverable. The model unit should include geometric information and geometric expression accuracy, attribute information and information depth, and data sources of attribute values.

[0159] Specifically, the model unit includes: project-level model unit, function-level model unit, component-level model unit and part-level model unit. The content is as follows:

[0160] (1) Project-level model unit: such as hub layout diagram, which carries project, sub-project or local engineering information.

[0161] (2) Functional level model unit: such as power generation building model, which carries complete functional system or space information.

[0162] (3) Component-level model unit: For example, a turbine model carries the information of a single component.

[0163] (4) Part-level model unit: For example, a turbine blade model carries the component parts or installation parts information of a component.

[0164] The geometric accuracy requirements for model units include: model fineness in the survey and design pre-feasibility study stage, model fineness in the survey and design feasibility study stage, model fineness in the survey and design construction drawing stage, and model fineness in the construction management stage and operation and maintenance stage.

[0165] Specifically, the refinement requirements of the model unit are as follows:

[0166] (1) The model precision of the survey, design and pre-feasibility study stage shall not be less than LOD1.0, and the smallest model unit shall be the project-level model unit;

[0167] (2) The model precision of the survey, design and feasibility study stage shall not be less than LOD2.0, and the minimum model unit shall be the functional level model unit;

[0168] (3) The model precision of the survey, design and construction drawing stage shall not be less than LOD3.0, and the smallest model unit shall be the component-level model unit;

[0169] (4) The model resolution during the construction management and operation and maintenance phases shall not be less than LOD4.0, and the smallest model unit shall be the part-level model unit.

[0170] The model building module 72 is used to build a hydropower project BIM model based on the hydropower project model data standard.

[0171] In this embodiment, building components are modeled and their attributes are defined based on the hydropower engineering model data standard to obtain a hydropower engineering BIM model.

[0172] Specifically, the BIM model is constructed on the basis of establishing data standards. Standardized data specifications are used to model and define the properties of building components to ensure the integrity and accuracy of model data. The constructed model must meet the accuracy requirements of the delivery and contain all necessary attribute data. The modeling is completed according to the characteristics of each specialty of hydropower engineering.

[0173] Based on the needs of different majors, choose the modeling tools corresponding to each major.

[0174] In this embodiment, in order to meet the needs of various professions, suitable modeling software is selected for modeling; according to the characteristics of hydropower projects and the needs of different professions, the workspace is customized and deployed; wherein the workspace includes: layers, category styles, line types and line widths, colors, display styles, and any one or more combinations in the component library; selection of modeling base points; selection of key areas for refined modeling; modeling is performed on a three-dimensional collaborative management platform to obtain a BIM model of the hydropower project.

[0175] In this embodiment, the workspace and deployment are customized. According to the characteristics of hydropower projects and the needs of different disciplines, a project-level workspace is formulated. The workspace not only specifies the layers, category styles, line types and line widths, colors and display styles, but also contains a library of commonly used components to ensure that each discipline is modeled under a unified standard.

[0176] Determine the positioning benchmark of the unified model to ensure the consistency and accuracy of each professional model. For some buildings that cannot be positioned using the plant axis grid, a control point positioning method with absolute position as the control point is used.

[0177] Due to the wide scope and rich content of hydropower projects, different regions have different requirements for the geometric expression accuracy and attribute depth of the model. Therefore, according to the actual application needs, key areas are selected for refined modeling to ensure the practicality and accuracy of the model.

[0178] Modeling, subassembly and final assembly are carried out on the 3D collaborative management platform. Through the collaborative work function of the platform, various disciplines can share model data in real time to improve work efficiency and collaborative effects.

[0179] The digital delivery module 73 is used to perform analysis based on the hydropower engineering BIM model to obtain a analyzed hydropower engineering BIM model.

[0180] The hydropower engineering BIM model is parsed, and the parsed data is imported into a digital delivery platform; the parsed data adopts structured data.

[0181] In this embodiment, the hydropower project BIM model is lightweight processed to extract structured data; the lightweight processing includes: geometric information extraction and attribute information extraction.

[0182] The geometric information extraction is to perform geometric data serialization processing on different types of geometric objects through a specific interface, and then output the geometric data by calling a function.

[0183] The attribute information extraction is to obtain the attribute library defined in the model file, then traverse the attribute groups and attribute items in each attribute library, and find the value corresponding to each attribute field in the hydropower engineering BIM model.

[0184] Deliver the objects and attributes in the hydropower project BIM model to the digital delivery platform.

[0185] After lightweight processing of the hydropower project BIM model, the KV collection of each model component can be obtained. The system can configure the asset code (UUID) to aggregate the attributes and return it in the form of a list of UUID and attribute key-value pairs.

[0186] In this embodiment, attribute acquisition is performed to extract the attribute key value set of each model component from the hydropower project BIM model. The attributes include: size, material, location and other related parameters. Then, asset aggregation is performed. Through system configuration, the corresponding asset code and attribute are aggregated to obtain a list of asset code and attribute key value pairs. The asset code set is then traversed to create a new object for each asset code. Attributes are assigned to the new object, and the new object and attributes after attribute assignment are delivered to the digital delivery platform.

[0187] Deliver the drawings and documents in the hydropower project BIM model to the digital delivery platform. According to the drawing identification code and document identification code (Key) configured by the system, the system will download relevant drawings and documents from different systems according to the URL address in the corresponding value, and store them on the digital delivery platform. Subsequently, users can edit the properties of these drawings and documents and preview the files through the platform.

[0188] In this embodiment, the attribute key value set of the model component in the hydropower project BIM model is configured to obtain a drawing identification code and a document identification code; address resolution is performed based on the drawing identification code and the document identification code to obtain a URL address containing the target file; based on the URL address, the required downloaded images and documents are obtained and stored in the digital delivery platform.

[0189] Deliver the coded association relationship in the hydropower project BIM model to the digital delivery platform.

[0190] In this embodiment, the system manages the above key-value set according to the configured business system identification code (Key). Based on the value corresponding to the identification code (Key), the system can effectively manage the corresponding object. Based on this mapping relationship, the extended information of the business system can be easily found later. This method not only improves the accuracy of system management, but also simplifies the information retrieval and processing process.

[0191] An engineering breakdown structure automatically generated based on the object is delivered to a digital delivery platform.

[0192] Based on the delivery of object data, the rules of object coding can generate a tree of engineering decomposition structure. The hydropower engineering object coding consists of a general coding combination and a subclass coding. The general coding combination is used to identify the plant and specialty to which the element belongs, and the subclass coding is used to classify the asset elements into three categories: civil engineering, electromechanical equipment, and space.

[0193] In this embodiment, the hydropower project analysis is performed according to the rules of object coding, a hydropower project decomposition structure tree is generated, and the structure is delivered to the digital delivery platform.

[0194] Specifically, the object code includes: a code combination and a subclass code. The code combination includes a plant code and an asset classification code, which is used to identify the plant and specialty to which the element belongs; the subclass code is used to classify the asset elements into three categories: civil engineering, electromechanical equipment, and space for identification.

[0200] Writing scripts according to the above coding rules can automatically generate a decomposition structure tree.

[0201] The display module 74 is used to display the parsed hydropower engineering BIM model on the digital delivery platform.

[0202] In this embodiment, based on the digital delivery results of the analyzed hydropower engineering BIM model, the digital delivery platform provides a variety of functions to improve the visualization and manageability of data. These functions include: model preview, drawing and document preview, and the linkage between the engineering decomposition structure tree and the model, allowing users to view objects and their corresponding attributes; that is, hydropower engineering BIM model preview, drawing and document preview, the linkage between the engineering decomposition structure tree and the model, object and attribute viewing, data support business applications, archiving basic data and other functions.

[0203] The digital delivery model of hydropower projects based on BIM models builds a digital delivery system for hydropower projects based on BIM models. By establishing modeling data standards, standardizing modeling, parsing BIM models, and realizing the digital value of projects, the delivery efficiency of BIM models and the value of data utilization can be improved.
