Description

Technical Field

[0001] This invention relates to a digital twin-based visualization management system for the entire lifecycle of municipal engineering projects, belonging to the interdisciplinary field of information technology and civil engineering. Background Technology

[0002] Municipal engineering generally falls under the category of national infrastructure construction. It refers to the construction of various public transportation facilities, water supply, drainage, gas supply, urban flood control, environmental sanitation, and lighting infrastructure in urban construction. It is an indispensable material foundation for the survival and development of cities. Municipal engineering projects, such as urban roads, bridges, tunnels, and underground pipe networks, are the lifeline for ensuring the normal operation of cities.

[0003] With the acceleration of urbanization, municipal engineering projects are becoming increasingly complex, and traditional project management methods are no longer sufficient to meet the demands for efficient, accurate, and visualized management. Currently, municipal engineering project management mainly suffers from the following problems: severe information silos: data at each stage of the project (planning, design, construction, operation and maintenance) is scattered, lacking a unified data management and sharing mechanism, making it difficult to effectively integrate and utilize data; insufficient decision support: the lack of integrated analysis of data throughout the entire project lifecycle makes it difficult to provide managers with scientific and timely decision support; low collaborative work efficiency: low collaborative work efficiency among project participants (such as owners, design, construction, supervision, and operation and maintenance units), poor information transmission, easily leading to design changes, construction conflicts, and rework, increasing project costs and schedule risks. Based on this, this invention provides a visualized management system for the entire lifecycle of municipal engineering projects based on digital twins. Summary of the Invention

[0004] The technical problems that this invention aims to solve are: severe information silos, which make it difficult to effectively integrate and utilize data; insufficient decision support; low efficiency of collaborative work, which increases project costs and schedule risks.

[0005] To address the technical problems, this invention provides a digital twin-based full lifecycle visualization management system for municipal engineering projects. The proposed technical solution includes:

[0006] The data acquisition layer is used to collect multi-source data in real time at all stages of the entire life cycle of municipal engineering projects, including geographic information data, building information model data, IoT sensor data, and construction process data.

[0007] The digital twin model building layer is used to construct high-precision, dynamically updatable digital twin models of municipal engineering projects based on collected multi-source data, including geometric models, physical models, behavioral models, and rule models.

The data storage module adopts a distributed database and object storage to support the storage of structured and unstructured data. The data management module implements data classification, encoding, version control, and access control. The data sharing module provides a standard API interface to support data exchange and sharing with other systems. The data security module uses encryption, authentication, and access control technologies to ensure data security.

[0016] Furthermore, this system supports dynamic updates of the digital twin model, including real-time updates based on IoT sensor data, phased updates based on construction process data, periodic updates based on operation and maintenance monitoring data, and supplementary updates based on manually entered data.

[0024] The preferred embodiments of the present invention will now be described in detail.

[0025] This invention provides a digital twin-based visualization management system for the entire lifecycle of municipal engineering projects, comprising:

[0026] The data acquisition layer is used to collect multi-source data in real time at all stages of the entire life cycle of municipal engineering projects. The multi-source data includes geographic information data (GIS), building information modeling data (BIM), Internet of Things (IoT) sensor data, and construction process data. The data acquisition layer supports multiple data access methods, including interfacing with GIS systems to obtain geospatial data of the project area, interfacing with BIM software to obtain design model data of the project, interfacing with IoT sensor networks to collect environmental, equipment, and structural monitoring data of the project site in real time, and supporting manual entry of construction process data, including construction logs, quality inspection records, and material usage records.

[0027] The digital twin model construction layer is used to build high-precision, dynamically updatable digital twin models of municipal engineering projects based on collected multi-source data. The digital twin model includes geometric models, physical models, behavioral models, and rule models. The digital twin model construction layer adopts a multi-scale modeling method, which includes macro-scale, building a city information model (CIM) at the project area level, integrating GIS data, terrain data, and municipal facility data; meso-scale, building a project-level BIM model, integrating professional models such as architecture, structure, MEP, and municipal pipelines; and micro-scale, building a refined model at the key component level, integrating IoT sensor data to achieve real-time mapping of component-level status.

[0028] The visualization layer is used to visualize all stages of a project's entire lifecycle based on a digital twin model and through a dynamic visualization engine. Visualization includes project planning, design scheme comparison, construction progress simulation, and operation and maintenance status monitoring. The visualization layer uses WebGL, Unity3D, or Unreal Engine dynamic visualization engines, which support multi-terminal display, multi-view display, multi-dimensional display, and interactive operations. Multi-terminal display includes PC, mobile, and large-screen terminals; multi-view display includes first-person, third-person, and bird's-eye view; multi-dimensional display includes spatial, temporal, and attribute dimensions; and interactive operations include model roaming, information querying, scheme switching, and data filtering.

[0029] The full lifecycle management application layer provides management application functions for each stage of the project lifecycle, based on digital twin models and visualization. These functions include planning analysis, design optimization, construction management, and operation and maintenance decision support. The application layer comprises modules for planning analysis, design optimization, construction management, and operation and maintenance decision support. The planning analysis module, based on the CIM model, performs project site selection analysis, traffic impact analysis, and environmental impact analysis. It visually analyzes the relationship between the project and the surrounding road network and environmentally sensitive points, and performs viewpoint analysis and sunlight analysis to assist planning decisions. The design optimization module, based on the BIM model, performs design scheme comparison, clash detection, energy consumption analysis, and daylighting analysis. It also performs building energy consumption simulation, natural lighting analysis, and emergency evacuation simulation to optimize design schemes. Construction management... Based on construction process data and digital twin models, the module simulates construction progress, optimizes construction resources, and monitors construction quality and safety. By modeling construction resources such as tower cranes and transport vehicles, it can optimize construction site layout and simulate hoisting paths. Combined with on-site cameras and AI recognition technology, it can monitor and warn workers in real time about behaviors such as wearing safety helmets and entering dangerous areas. The operation and maintenance decision support module, based on operation and maintenance monitoring data and digital twin models, assesses the operating status of equipment and facilities, predicts faults, and formulates maintenance plans. Through machine learning analysis of historical data, it establishes equipment health assessment models and fault prediction models, realizing the transformation from passive maintenance to "predictive maintenance". When a fault occurs, the system can quickly locate the fault point on the model and automatically push related drawings, contingency plans, and maintenance manuals to guide operation and maintenance personnel to handle the situation quickly.

[0030] The data management and sharing layer is used to achieve unified storage, management, sharing, and exchange of data throughout the project lifecycle, ensuring data security, integrity, and consistency. This layer includes a data storage module, a data management module, a data sharing module, and a data security module. The data storage module uses a distributed database and object storage, supporting the storage of both structured and unstructured data. The data management module implements data classification, encoding, version control, and access control. The data sharing module provides standard API interfaces to support data exchange and sharing with other systems. The data security module employs encryption, authentication, and access control technologies to ensure data security.

[0031] In addition, this system has two key features: it supports dynamic updates of the digital twin model, including real-time updates based on IoT sensor data, phased updates based on construction process data, periodic updates based on operation and maintenance monitoring data, and supplementary updates based on manually entered data; and it supports multi-user collaborative work, including multi-role user permission management, multi-user online collaborative editing, multi-department data sharing and business collaboration, and collaborative management of all project participants (owner, design, construction, supervision, and operation and maintenance).
