[0002] Currently, under the dual-carbon development context, thermal power units need to transform towards higher efficiency, greater flexibility, and longer lifespan. The safety status and lifespan management of their metal components directly impact unit energy consumption, reliability, and service life. Therefore, it is imperative to accelerate digital transformation and the rapid integration of the traditional thermal power industry with information technology, digitalization, networking, and intelligence.

This will build new corporate advantages, further enhance core competitiveness, improve production efficiency and asset operation levels, and empower enterprises to improve quality and efficiency. While some research results exist on 3D modeling of thermal power units, no reports have been published on 3D modeling methods for full-space information of metal components.

[0003] Among related technologies, there are already some research results on three-dimensional modeling of thermal power units.

For each pipe, elbow, weld, etc., the system constructs a three-dimensional vector digital model for each component according to its actual size, and can combine these models step by step to support cross-scale visualization from micro-parts to macro-systems, and carry data for the entire life cycle of the equipment.

[0059] Furthermore, the models of each equipment component are aligned with the power plant's overall layout. The components are then organized hierarchically according to the system classification and ledger classification of the equipment ledger. A unique code ID is added to each part, containing information such as its unit, system, equipment, type, row, root, and section. The part ID is then used to associate, interact with, and integrate with other types of data.

[0060] like Figure 7 As shown, this application embodiment allows for the free combination and splitting of device digital models, generating thumbnails for each 3D model and displaying them in a model library for preview, enabling users to quickly preview and identify the models. Simultaneously, various model styles such as points, lines, surfaces, volumes, and text are created, allowing thumbnails to be resized, modified, or deleted as needed. The digital models constructed in this application embodiment possess high precision, are divided into independent objects according to device components, and have a more direct and smooth association and interaction with data.

[0061] This application embodiment can acquire three-dimensional data based on equipment design drawings, standardize the ledger data, construct a three-dimensional digital model of the full space information of the metal components of thermal power units, and generate an image library. By aligning with the power plant general layout, hierarchical assembly, coding and identification, and thumbnail generation, the image library can be managed in a standardized manner, thus forming the basis for complex multi-dimensional information synthesis and visual analysis. At the same time, it can reflect the specific parameters, details and characteristics of the equipment. Each component is an independent object and is accurately associated with attributes and operating condition data, realizing the accurate digital presentation of metal components from macro layout to micro structure, and providing a high-precision benchmark model for professional applications such as life assessment and stress analysis.

[0062] In step S103, based on the image library, multi-source spatiotemporal data of thermal power unit metal components are fused to obtain unified spatiotemporal data. The unified data is then input into the three-dimensional digital model of the full-space information of the thermal power unit metal components, and management actions for the entire life cycle of the thermal power unit metal components are performed to generate three-dimensional visualization information of the thermal power unit metal components.

[0063] It is understood that the multi-source spatiotemporal data in this application embodiment can be understood as a data set formed by combining data in the time dimension with model data in the spatial dimension; unified data can be understood as a comprehensive dataset with spatiotemporal reference formed after fusion processing, which can support querying and analysis by time axis or spatial location; and three-dimensional visualization information of metal components can be understood as a visualization output of component state evolution information presented through color mapping, dynamic charts and other methods on the basis of a three-dimensional digital model of the full space information of the metal components of thermal power units.

[0064] In actual implementation, the embodiments of this application can be based on the constructed three-dimensional digital model of the full space information of metal components, and access multi-source data such as production, manufacturing, installation, maintenance, testing and supervision in the time dimension to realize the fusion and synthesis of different types of data in the spatial and temporal dimensions, so as to obtain unified data after spatiotemporal fusion. The unified data with spatiotemporal characteristics is then input into the three-dimensional digital model of the full space information of the thermal power unit metal components to perform management actions for the entire life cycle of the thermal power unit metal components, so as to generate three-dimensional visualization information of the thermal power unit metal components.

[0065] This application embodiment utilizes a spatiotemporal correlation feature model to drive visualization, achieving an intuitive mapping of the state evolution process in a three-dimensional scene. It provides multiple perspectives, supporting multi-dimensional analysis and observation by operators, enabling them to easily view and understand the digital model. The digital model supports interactive operation, allowing operators to control and intervene. Users can directly select any component on the model to retrieve related historical maintenance records, real-time operating parameters, and analysis reports in real time, shifting the operation mode from "viewing the model" to "checking the status," significantly improving the directness and depth of analysis and decision-making. The digital model can be updated promptly, reflecting the actual operating status of the power plant and providing timely feedback to operators. Single-line diagrams and physical diagrams are synchronized, facilitating the generation of inspection and maintenance diagrams. Relying on a unified spatiotemporal data fusion architecture, the model can automatically associate and integrate real-time monitoring data, dynamically updating component status and ensuring that the visualization is synchronized with the physical world. The creation and modification of digital models for each metal component are simple, and network publishing requires no additional processing, facilitating comprehensive management of metal components and greatly improving the update efficiency and collaborative application convenience of the model throughout its entire lifecycle management.

[0066] The embodiments of this application can obtain unified data by fusing multi-source spatiotemporal data based on an image library, and then generate three-dimensional visualization information by combining the unified data, thereby supporting operators to perform multi-dimensional analysis and observation, enabling operators to easily view and understand the digital model, and providing strong support for status assessment and fault early warning.

[0067] Optionally, in one embodiment of this application, multi-source spatiotemporal data of thermal power unit metal components are fused based on an image library to obtain unified spatiotemporally fused data. This includes: acquiring multi-source data in the time dimension based on a data structure; fusing multi-source data in the time dimension based on a three-dimensional digital model of the full-space information of the thermal power unit metal components to obtain multi-source spatiotemporal data; mapping and integrating the multi-source spatiotemporal data based on an image library to obtain an association index for the multi-source spatiotemporal data; and constructing a spatiotemporal database of thermal power unit metal components based on the multi-source spatiotemporal data and the association index to obtain unified data.

[0068] It is understood that the multi-source data in the time dimension of this application embodiment may include multi-source data such as production, manufacturing, installation, maintenance, testing and supervision; the association index can be understood as an identifier used to associate multi-source spatiotemporal data, which facilitates the rapid retrieval and association of data; the spatiotemporal database can be understood as a dedicated database used to store and manage multi-source spatiotemporal data, which can realize efficient storage and convenient access to spatiotemporal data.

[0069] For example, the embodiments of this application can perform data alignment and standardization, including the unification of spatial coordinate systems and time bases. In the spatial dimension, the local coordinate system of the equipment's three-dimensional model (such as the center point of the boiler) is aligned with the overall coordinate system of the plant area. In the time dimension, a unified timestamp is added to the sensor data, and missing values ​​are interpolated to complete them.

[0070] Specifically, a semantic association model is established based on the metal component coding ID. A unique coding ID is added to each part in the 3D model, containing information such as its unit, system, equipment, type, row, root, and segment. By binding the part ID with other types of data, the association, interaction, and integration of information are realized, achieving accurate mapping and integration between the 3D model, attribute data, monitoring records, and documents.

[0071] Furthermore, a hierarchical spatiotemporal database architecture integrating spatial data, temporal data, and relational indexes is constructed. This architecture merges spatial data containing equipment model and location information from 3D digital model files, connects to the SIS system in real-time, extracts real-time temporal data, and downloads and stores reconstructed monitoring data files required by the system. It also establishes associations and bindings with other data types, including records in relational databases and external data files, through part IDs, providing a unified data foundation for comprehensive management and dynamic visualization of all spatial information. This enables dynamic mapping, accurately projecting real-time and business data to the corresponding spatial locations in the 3D model, achieving spatiotemporal prediction. Based on historical and real-time fused data, it predicts key indicators such as equipment lifespan and provides decision support for maintenance plans. By combining the equipment's spatial structural state and temporal evolution trends, it generates optimized operation and maintenance strategies.

[0072] like Figure 8 As shown, embodiments of this application may include the following steps: Step S801: Multi-source data access.

[0073] In this embodiment, the time dimension data, production and installation data, maintenance and testing data, and supervision and monitoring data can be integrated based on the constructed three-dimensional digital model of the full space information of the metal component.

[0074] Step S802: Data processing and fusion.

[0075] Among them, such as Figure 9 As shown, the embodiments of this application can achieve spatial alignment by unifying the local and global coordinate systems, and achieve time alignment by unifying timestamps and interpolation completion; after data alignment and standardization, the embodiments of this application can achieve multi-source information association and integration based on component code ID to achieve semantic association.

[0076] Step S803: Construct a spatiotemporal database.

[0077] In this embodiment, the spatiotemporal database may include spatial data, time-series data, and associated indexes. Spatial data includes 3D models and locations; time-series data includes real-time and historical monitoring data; and associated indexes include relationship databases bound by IDs. This embodiment can integrate multi-source spatiotemporal data to achieve a unified data foundation, supporting comprehensive management and dynamic visualization.

[0078] This application embodiment can access production, manufacturing, installation, maintenance, testing and supervision data in the time dimension, realize the fusion and synthesis of different types of data in the spatial and temporal dimensions, and drive visualization through spatiotemporal correlation feature model, realize the intuitive mapping of the state evolution process in the three-dimensional scene, and build a spatiotemporal database to obtain unified data, so that the three-dimensional digital model of the full space information of the metal components of thermal power units has good visibility. Based on the unified spatiotemporal data fusion architecture, the model can automatically associate and integrate real-time monitoring data, dynamically update the component status, and ensure that the visualization presentation is synchronized with the physical world.

[0079] Optionally, in one embodiment of this application, unified data is input into a three-dimensional digital model of the full spatial information of the thermal power unit's metal components, and management actions throughout the entire lifecycle of the thermal power unit's metal components are performed to generate three-dimensional visualization information of the thermal power unit's metal components. This includes: extracting and associating dynamic coupling features of the thermal power unit's metal components in the spatial and temporal dimensions based on unified data; establishing a quantitative coupling relationship between the spatial and temporal features of the thermal power unit's metal components based on the dynamic coupling features; inputting the spatial and temporal features with the quantitative coupling relationship into the three-dimensional digital model of the full spatial information of the thermal power unit's metal components, and performing management actions throughout the entire lifecycle of the thermal power unit's metal components to output three-dimensional visualization information of the thermal power unit's metal components.

[0080] It is understood that the dynamic coupling feature in the embodiments of this application can be understood as the interrelationship characteristics of the component state in terms of spatial distribution and temporal evolution, such as local high temperature distribution leading to material creep and long-term overheating causing fatigue damage. The quantitative coupling relationship can be understood as the quantitative relationship between the established spatial features and temporal features. The management actions of the entire life cycle can include state assessment, life prediction, maintenance plan formulation, etc.

[0081] In practical implementation, this application embodiment can extract and associate the dynamic coupling characteristics of the device in the spatial and temporal dimensions based on the unified data foundation after spatiotemporal fusion. Spatial characteristics include the geometric structure, deployment location, and topological connection relationship of the component. Then, temporal characteristics include continuous state changes monitored by sensors, maintenance event records, and long-term performance evolution trends, synchronously tracking its dynamic state evolution and discrete event sequences. Specifically, it covers everything from real-time sensor monitoring data to performance indicators reflecting long-term deterioration trends, as well as historical records of various maintenance operations and emergencies. Finally, a quantitative coupling relationship between spatial and temporal characteristics is established through correlation analysis algorithms. The spatiotemporal characteristics of the correlation model are input into the three-dimensional model, specifically manifested as the constraints of spatial structural characteristics on the temporal evolution process (such as material creep caused by local high temperature distribution) and the reshaping of spatial state by the time accumulation effect (such as fatigue damage caused by long-term overheating). On this basis, an interactive capability is formed that supports the tracing and exploration of historical states based on spatial location in the three-dimensional model, realizing comprehensive management of metal components from static design to dynamic operation and maintenance.

[0082] Furthermore, the digital model constructed in this application embodiment determines its standard color, spatial location, and orientation based on various drawings, data, and the actual conditions of equipment and pipelines. For example... Figure 10 As shown, this application embodiment can interface the equipment's historical maintenance information with the equipment's digital model. The model can categorize and display its detailed information, such as size, material, process, defects, replacement, maintenance records, etc., making information recording more diversified, hierarchical, and accurate. This application embodiment allows viewing the equipment status through different perspectives and zoom, providing professionals with a good auxiliary tool. At the same time, it independently describes, records, and manages the information of equipment components, achieving full lifecycle management of equipment components.

[0083] This application embodiment can extract and associate the spatiotemporal dynamic coupling characteristics of metal components from unified data, establish a quantitative coupling relationship of spatiotemporal characteristics, integrate them into the three-dimensional digital model of the equipment's full-space information, and manage the entire life cycle of metal components to output three-dimensional visualization information. This supports operators in performing multi-dimensional analysis and observation, enabling operators to easily view and understand the digital model, and retrieve historical maintenance records, real-time operating parameters, and analysis reports of any metal component in real time, significantly improving the directness of analysis and decision-making and the convenience of collaborative application.

It generates and manages image libraries of various three-dimensional component models, enabling the fusion and synthesis of different types of data in both spatial and temporal dimensions. This results in unified data and the generation of three-dimensional visualization information, effectively integrating complex data from multiple sources throughout the entire product lifecycle. It achieves accurate digital representation of metal components from macroscopic layout to microscopic structure, facilitating comprehensive management of metal components. This method features accuracy, precision, visibility, interactivity, real-time performance, and ease of use. Therefore, it solves the problem in related technologies where the large number and complex structure of metal components in large thermal power units, along with the numerous and varied specifications and quantities of design, installation, and annual maintenance technical data related to each component, lead to a lack of systematic organization and analysis, the absence of a unified and user-friendly management platform, and difficulty in supporting precise and predictive operation and maintenance.
