Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy project management, and in particular to a water conservancy project management method and system based on digital twins. Background Art

[0002] With the rapid development of the Internet of Things, cloud computing and big data technologies, digital twin technology has gradually become an important means to improve the management efficiency of water conservancy projects. Digital twins can effectively integrate various sensor data by creating virtual models of physical water conservancy facilities and real-time monitoring and analysis of them, and reflect hydrological, meteorological and water resource changes in real time. Through high-precision sensors and remote sensing technology, the operation data of water conservancy projects, including key parameters such as water level, flow rate, and pressure, are collected in real time. The digital twin model is built using these data to dynamically reflect the physical state of water conservancy facilities. The digital twin model can provide real-time monitoring capabilities, allowing managers to view the operating status of water conservancy facilities at any time. Through data analysis algorithms, potential faults and risks can be identified, early warning capabilities can be improved, and the safe and stable operation of facilities can be ensured. Environmental data such as meteorology and hydrology can be integrated into the digital twin model to enhance the adaptability to changes in external factors. It can simulate the performance of the project under different environmental conditions and support decision makers in formulating more scientific management strategies. However, traditional water conservancy project management methods rely on offline data analysis, which makes it difficult to reflect the state changes of water conservancy projects in real time, and have poor adaptability to environmental change factors.

[0061] Beneficial effects of the present invention:

[0062] 1. Compared with the prior art, the water conservancy project management method based on digital twin proposed by the present invention has the beneficial effect of providing detailed structural design data for water conservancy projects by extracting engineering structure design data from engineering design drawings corresponding to water conservancy projects. This step not only ensures the accuracy of design data, but also provides a solid foundation for subsequent monitoring and evaluation. By dynamically monitoring and collecting operation data of water conservancy projects, the operation data of the project can be obtained in real time. This process enables project managers to understand the operation status of the project in a timely manner, including key indicators such as water flow, pressure, and temperature. Dynamic monitoring can not only improve the operation efficiency of the project, but also respond quickly when abnormal situations occur, reducing potential risks. By real-time monitoring and collection of the surrounding environment of the water conservancy project, the environmental changes around the water conservancy project can be understood in detail. This process can capture environmental data such as water quality, soil moisture, and rainfall, providing important external reference information for the operation of the water conservancy project. At the same time, by conducting digital twin spatial modeling of the corresponding water conservancy project based on the water conservancy project design data, a digital model corresponding to the actual water conservancy project structure can be constructed. This model not only accurately reflects the structural characteristics and operating status of the water conservancy project, but also can perform virtual simulation and predictive analysis. The digital twin model provides an intuitive visualization tool for the management of water conservancy projects. Engineers can simulate various scenarios of the project in a virtual environment and evaluate the performance of the project under different operating and environmental conditions, thereby providing a solid guarantee for the realization of more efficient and safer water conservancy project operation. Secondly, by conducting virtual simulation analysis of the operating conditions of the digital twin spatial model of the water conservancy project based on the water conservancy project operation data and water conservancy project environmental data, the simulation operation process sub-model under different operating operations and environmental change conditions can be obtained. This analysis can provide deep insights for managers of water conservancy projects and help understand the behavior and performance of the project under different conditions. Through virtual simulation, engineers can identify potential operating risks and optimize operating strategies to improve the efficiency and safety of the project. It also lays the foundation for future technical improvements and management decisions, so as to better reflect the changes in the operating status of the water conservancy project in real time and promote the development of water conservancy projects in a more intelligent and efficient direction. Then, by simulating and analyzing the changes in water flow distribution in the sub-model of the hydraulic engineering simulation operation process under different operating operations and environmental changes, the water flow distribution behavior under different operating and environmental conditions can be more intuitively displayed. This simulation analysis not only helps to understand the distribution characteristics of water flow under different conditions, but also provides an intuitive basis for engineering design. By simulating the distribution scenario of water flow, the changing laws of fluid dynamics can be identified, and then the impact on the engineering structure can be evaluated.By analyzing the engineering structure stress load of the corresponding hydraulic engineering simulation operation process sub-model based on the simulation field of water flow distribution change of hydraulic engineering under different operation and environmental change conditions, the safety and stability of hydraulic engineering under different operation and environmental conditions can be evaluated. The structural stress load is an important factor affecting the safety of the project. Accurate stress analysis can help identify potential safety hazards and guide engineering design and maintenance. Through this analysis, we can better understand the force of water flow on the engineering structure, thereby providing the necessary basis for structural design, ensuring the reliability of water conservancy facilities in actual operation, and providing guidance for the transformation and upgrading of hydraulic engineering to improve its ability to cope with extreme weather and environmental changes, thereby improving the adaptability of subsequent engineering management processes to environmental change factors. Finally, by conducting engineering operation risk assessment on the corresponding hydraulic engineering simulation operation process sub-model based on the simulation field of water flow distribution change of hydraulic engineering under different operation and environmental change conditions and the stress load data of hydraulic engineering structure, we can systematically identify the potential risks of hydraulic engineering under different conditions. The results of risk assessment will provide important reference for decision makers, enabling them to more accurately grasp the safety status and potential hazards of the project. This process can not only identify the current risk points, but also predict the possible risk situations in the future through comprehensive analysis of historical data and existing models, and provide data support for scientific decision-making. In addition, by conducting risk decision management on the corresponding water conservancy projects based on the risk data of the simulated operation process of water conservancy projects under different operating operations and environmental changes, risk management decisions that meet the actual situation can be systematically formulated. This process combines the theory and practice of risk management, and ensures that water conservancy projects can effectively respond to various risk conditions through the evaluation and optimization of specific implementation plans. The generation of this decision will consider a variety of factors, such as the current operation status of the project, changes in the external environment, historical data analysis, etc., so as to formulate a scientific and reasonable adjustment plan. After implementing these decisions, it is possible to respond to emergencies in a timely manner, reduce losses and improve the overall resilience of water conservancy projects. In addition, through systematic risk management decisions, not only the operating efficiency of water conservancy projects is improved, but also a reliable reference basis is provided for the future water conservancy project management process, thereby promoting the sustainable development of water conservancy project management.

The water conservancy project management system based on digital twin proposed in the present invention is composed of a water conservancy project digital twin spatial modeling module, an operation and environmental change condition simulation module, a water flow distribution and structural force load analysis module and a water conservancy project operation risk management module. It can realize any water conservancy project management method based on digital twin described in the present invention, and is used to combine the operations between computer programs running on each module to realize the water conservancy project management method based on digital twin. The internal structures of the system cooperate with each other, which can greatly reduce duplication of work and manpower investment, and can quickly and effectively provide a more accurate and efficient water conservancy project management process based on digital twin, thereby simplifying the operation process of the water conservancy project management system based on digital twin.

[0076] In the embodiment of the present invention, please refer to Figure 1As shown, it is a schematic diagram of the steps of the water conservancy project management method based on digital twins of the present invention. In this example, the water conservancy project management method based on digital twins includes the following steps:

[0077] Step S1: Acquire water conservancy project design data, water conservancy project operation data and water conservancy project environmental data, and perform digital twin space modeling on the corresponding water conservancy project based on the water conservancy project design data to obtain a digital twin space model of the water conservancy project;

[0078] In an embodiment of the present invention, by obtaining the engineering design drawings corresponding to the water conservancy project, including structural drawings, construction drawings and detailed design instructions, and using computer-aided design (CAD) software such as AutoCAD or Revit, the engineering design drawings are processed for obtaining structural design data, so as to extract structural parameters, including structural design parameters such as dam height, width, material type, and load-bearing capacity, by writing a program or using existing tools, so as to obtain the initial design data of the water conservancy project structure. By using a pre-configured real-time operation monitoring system (the system consists of sensors, data collectors and a central monitoring platform), the operation data of the water conservancy project is dynamically monitored and collected in real time, so that sensors are arranged at key positions of water conservancy project facilities, responsible for collecting operation parameters such as water level, flow, and pressure, and the data collector regularly transmits the sensor data to the central monitoring platform to realize real-time storage of all collected operation data, so as to obtain the operation data of the water conservancy project for dynamic monitoring. At the same time, the environmental changes around the water conservancy project are monitored and collected in real time by using water conservancy project environmental monitoring sensors. The environmental monitoring sensors are deployed in the surrounding areas of the water conservancy project. The monitoring parameters include air quality, soil moisture, rainfall and water quality. The data of each sensor is integrated to form a comprehensive environmental monitoring data set, so as to obtain real-time monitoring data of the environment around the water conservancy project. In addition, the initial design data of the water conservancy project structure, the operation data of the dynamic monitoring of the water conservancy project and the real-time monitoring data of the environment around the water conservancy project collected in real time are preprocessed to clean the corresponding data, remove duplicate or invalid information, and perform time series synchronization processing to ensure that all types of data are aligned according to a unified time dimension. The missing data points are filled by the interpolation algorithm to form continuous time series data, so as to obtain the water conservancy project design data, water conservancy project operation data and water conservancy project environmental data under the same time dimension. Then, by combining the water conservancy project design data obtained after time-series synchronization, the digital twin technology is used to perform spatial modeling of the corresponding water conservancy project. By using three-dimensional modeling software such as SketchUp or BIM platform, the design data and monitoring data of the water conservancy project are imported to build a digital model corresponding to the actual project. The model parameters are continuously updated using data-driven methods to maintain a high degree of consistency with the actual water conservancy project design structure, and finally a digital twin spatial model of the water conservancy project is obtained.

[0079] Step S2: Based on the water conservancy project operation data and water conservancy project environmental data, a virtual simulation analysis of the operation conditions of the water conservancy project digital twin space model is performed to obtain a water conservancy project simulation operation process sub-model under different operation operations and environmental change conditions;

[0080] In an embodiment of the present invention, a statistical analysis is performed on the water conservancy project operation data (including various parameters such as water flow, water level, pressure, temperature, etc.) previously analyzed by using, for example, time series analysis or principal component analysis to identify its changing trends, such as periodic changes, sudden changes or gradual changes, and a model is constructed to describe these changing patterns. A machine learning algorithm, such as cluster analysis, can be used to help identify operating modes under similar states, and by combining the operating state attribute change patterns obtained by the previous analysis, the simulation conditions of the operating operation process of the corresponding water conservancy project operation data are designed, so as to analyze the operating operation types under different change modes, including start and stop, flow regulation, water level adjustment and other operation methods, and set corresponding simulation conditions for each operation, including operation time, operation intensity, initial state, etc., so as to simulate and generate corresponding water conservancy project operation simulation conditions. At the same time, by combining the operating state attribute change pattern obtained by the previous analysis, the corresponding water conservancy project environmental data is subjected to correlation evaluation analysis of the operating environment change, so as to collect environmental data related to the water conservancy project, such as rainfall, evaporation, soil moisture, temperature, etc., and establish a mathematical model to correlate the environmental changes with the operating state attributes. By using statistical methods such as regression analysis, the relationship between the two is explored to form an impact correlation relationship between environmental changes and operating state attribute changes. By combining the impact correlation relationship obtained by the previous analysis, the corresponding water conservancy project environmental data is simulated and designed for the operating environment scenario, so as to simulate and design the main environmental change scenarios that need to be simulated, including extreme climate events (such as floods and droughts), seasonal changes and long-term trends, so as to form a complete environmental change scenario simulation condition. Then, by combining the previous simulation design The generated water conservancy project operation simulation conditions and water conservancy project operation environment change scenario simulation conditions perform simulation analysis on the corresponding water conservancy project digital twin space model of the operation condition combination, so as to combine the operation scenario and the environmental change scenario separately, and form corresponding simulation input condition systems, and use digital twin technology to create respective dynamic virtual environments through the simulation platform using various simulation input condition systems. In the corresponding virtual environment, different operating conditions are set to simulate the operation process of the water conservancy project under the interactive conditions of respective operation and environmental change. In the simulation analysis process, the changes of key indicators in each operation process, such as flow, water level, pressure, etc., are recorded, thereby forming an operation process sub-model under respective operation conditions, and finally obtaining a water conservancy project simulation operation process sub-model under different operation and environmental change conditions.

The changing rules, such as the maximum stress point, strain distribution and structural safety factor, are also combined with the dynamic change trend of water flow obtained in the previous analysis and the changing rules of stress state to build a comprehensive risk assessment model. This model uses the risk matrix method to combine the changing trend of water flow distribution with the changing rules of stress load state to evaluate the impact of potential risk factors on the operation of water conservancy projects. By using statistical analysis software (such as MATLAB), the data is processed to generate various risk indicators and evaluation results, including water pressure risk, flow velocity fluctuation, impact force, engineering structure strain, water level anomaly and engineering structure failure, etc., so as to obtain the risk data of the simulated operation process of water conservancy projects under different operating operations and environmental changes.

These data can be obtained through sensor networks, remote sensing technology, etc., and the data are spatially interpolated using GIS (geographic information system) tools to generate spatial distribution maps of flow rate and water level. By comparing the distribution maps under different time periods and climatic conditions, the changing trends and patterns of flow rate and water level can be identified. For example, in the management process of a specific reservoir, the changes in water level and the distribution differences in flow rate between the dry season and the rainy season can be analyzed, so as to understand the operating status of the reservoir under different environmental conditions, and finally obtain the spatial distribution characteristics of the water conservancy project operation flow rate and the spatial distribution characteristics of the water level change under different operation operations and environmental change conditions.

[0156] In an embodiment of the present invention, after completing the analysis of the spatial distribution characteristics of flow velocity and water level, the next step is to perform spatial distribution association mining analysis. This process requires statistical analysis of the correlation of the collected spatial distribution characteristics of the flow velocity of the water conservancy project and the spatial distribution characteristics of the water level change of the water conservancy project, so as to use spatial statistical methods, such as Kriging interpolation and regression analysis, to establish a mathematical model between flow velocity and water level. In specific implementation, different operating operations (such as irrigation, water storage, water release, etc.) and environmental change conditions (such as rainfall, evaporation, etc.) are first classified and compared with the spatial distribution characteristics obtained previously. By clustering data from different regions, the correlation between flow velocity and water level and its changing trend are found. For example, in the irrigation process of a water conservancy project, the relationship between the flow velocity change and the soil moisture water level during irrigation is analyzed, which can reveal the impact of different irrigation methods on the water level, and finally obtain the spatial distribution correlation between the flow velocity and water level change of the water conservancy project under different operating operations and environmental change conditions.

In the specific implementation process, the input parameters of the model are first determined, including flow rate, water level, meteorological conditions, etc., and modeling is performed using computational fluid dynamics (CFD) simulation software. The model is numerically simulated to simulate the change process of water flow under specific conditions. For example, in a water conservancy hub project, the inflow and outflow of the reservoir under heavy rainfall conditions and the spatial distribution of the influence of downstream water level changes can be simulated. Finally, the simulation scene of the water flow change of the water conservancy project under different operating operations and environmental change conditions is generated.

These data are used to analyze the force distribution of water flow on the water conservancy project structure, and finally obtain the force distribution data of the water conservancy project structure under different operating operations and environmental change conditions.

The specific method is to use the transient fluid mechanics theory to simulate the impact of different flow rates and flow directions, and select key time points under different water flow conditions to calculate the instantaneous impact force, focusing on analyzing the impact intensity caused by the collision between the fluid and the structure surface. In this process, the numerical integration method is used to quantify the water flow impact, for example, Where I(t) is the impact strength value of the water flow distribution at time t, T is the total impact time under the corresponding operation and environmental change conditions, A is the contact area between the water flow and the structural surface, ρ is the water flow density parameter, and v(t) is usually taken as 1000 kg / m 3 , v(t) is the water velocity at time t, v ref is the water flow reference velocity under the corresponding operation and environmental change conditions, δ(t―t i ) is the Dirac Delta function, which is used to represent the instantaneous impact time point t i, to ensure the calculation of the impact strength at a specific time point. This formula integrates the impact strength of the water flow on the contact surface. First, the water flow velocity at all times is integrated within the time range [0, T]. It combines the difference between the fluid density and the reference flow velocity to reflect the instantaneous impact force of the water flow on the structural surface under different conditions. By integrating over area A, the overall impact strength can be quantified, thereby obtaining the water flow distribution impact strength value under the corresponding operating conditions and environmental change conditions, and finally obtaining the water flow distribution impact strength value of the hydraulic engineering structure under different operating conditions and environmental change conditions.
