[0021] Hydropower stations are high-risk workplaces, involving dangerous factors such as high voltage electricity, high temperature, and mechanical movement. Due to the complex structure of hydropower station equipment, the large number of equipment, and the wide coverage area of ​​facilities, problems are very likely to occur during operation. Therefore, regular inspections are required to promptly discover potential safety risks, prevent accidents, and protect the safety of personnel and equipment. Among them, the gate system is an important control facility used to adjust the water level, control the water flow, and protect the safety of the project. The control method and operation and maintenance of the gate are crucial, but the related equipment structure of the gate system is complex and the number of components is large, resulting in a large workload for inspection; and when a problem occurs, it is impossible to find the problem in the first time, resulting in slow inspection speed and low inspection efficiency.

[0022] In order to solve the above problems, the present invention proposes a method for constructing a digital twin gate system.

[0023] See also Figure 1 In one embodiment of the present invention, the method for constructing a digital twin gate system includes: S100: Acquire actual operation data of a physical gate system, where the physical gate system at least includes an external structure and an internal operation structure; S200: In each operation device of the internal operation structure of the physical gate system, at least one sensor device is correspondingly provided to collect actual operation data to form a sensor monitoring network; S300: constructing a three-dimensional model according to the characteristics of the external structure and the internal operation structure of the physical gate system; S400: A digital twin gate system is established based on the three-dimensional model and the sensor monitoring network to form a mapping relationship between the operating device and the three-dimensional model; S500: Obtaining the operating data threshold of each operating device respectively; S600: comparing actual operation data of each operation device with the operation data threshold value individually; S700: When the actual operating data of any operating device exceeds the operating data threshold and the corresponding operating device is determined to be in a fault state, the digital twin gate system issues a maintenance reminder message.

[0024] By obtaining actual operation data from the external structure and internal operation structure of the physical gate system, and using modeling software to build a three-dimensional model of the physical gate system, by setting sensors in each key operation device, a comprehensive sensor monitoring network is constructed, and the constructed three-dimensional model is combined with the sensor monitoring network to form a mapping relationship between the operation device and the three-dimensional model, and a digital twin gate system is created, so that the digital twin gate system can reflect the status of the physical gate in real time; by using the digital twin gate system, the real-time operation status of the physical gate system can be fully reflected; operation data thresholds are set for each operation device, which are determined based on the technical specifications and historical operation data of the equipment to determine whether the equipment is operating normally; the actual operation data collected by the sensor device is compared with the preset threshold. If the data of any operation device exceeds the threshold, the system will determine that the operation device is in a fault state; once the system detects a fault state, the digital twin gate system will convey it to the operation and maintenance personnel by issuing a maintenance reminder message; due to the mapping relationship in the digital twin gate system, the exact location and related components of the fault can be quickly located, thereby speeding up the fault repair, which has the advantages of reducing the workload of troubleshooting and improving the troubleshooting speed.

[0025] In one embodiment, in each operation device of the internal operation structure of the physical gate system, at least one sensor device is correspondingly provided to collect actual operation data to form a sensor monitoring network step S200, which further includes the following steps: The actual operating data of the stress, deformation, wear, vibration frequency, temperature or annual corrosion rate of the operating device is collected through the sensor device to ensure that the digital twin gate system can reflect the actual operating status of the physical gate system.

[0026] Specifically, appropriate sensor types can be selected according to the characteristics of the operating devices of the physical gate system, such as stress sensors, displacement sensors, wear sensors, vibration sensors, temperature sensors, and corrosion sensors; the sensors collect data such as stress, deformation, wear, vibration frequency, temperature, and annual corrosion rate of the gate operating devices in real time, reflecting the physical and chemical effects that the gate is subjected to in actual operation, and can be used to judge the operating health of the physical gate system; these sensors are deployed at various key operating locations of the physical gate system to ensure that the operating status of the gate can be fully monitored; the processed actual operating data is updated in real time to the digital twin gate system, so that the digital twin model can reflect the actual operating status of the gate; the digital twin gate system uses these data to simulate the physical behavior of the physical gate system and predict potential failures and performance degradation.

[0027] In one embodiment, after step S200 of setting at least one sensor device in each operation device of the internal operation structure of the physical gate system to collect actual operation data to form a sensor monitoring network, the following steps are also included: Obtain environmental operation data of the external structure of the physical gate system, the environmental operation data including water level, gate flow, ambient temperature data and ambient humidity; Perform data preprocessing operations such as cleaning, filtering, and denoising on environmental operation data; Convert the preprocessed environment operation data into a format suitable for UE5 (Unreal Engine 5).

[0028] Specifically, sensors are deployed on the external structure of the physical gate system to monitor key environmental parameters such as water level, gate flow, ambient temperature and ambient humidity in real time; the collected environmental operation data is preprocessed by data cleaning, filtering, denoising, etc. to improve the quality and availability of the data; the preprocessed environmental operation data is converted into a format suitable for UE5, and corresponding variables or data structures are created in UE5 to store environmental data. The data binding function of UE5 is used to associate environmental data with corresponding parameters in the digital twin model to achieve real-time data updates. Environmental operation data can be used to simulate the behavior of the physical gate system under different environmental conditions in UE5, such as the impact of water level changes on gate operation. The digital twin gate system can more comprehensively simulate and predict the behavior of the physical gate system in the actual environment, improving the reliability and maintenance efficiency of the system.

[0029] In one embodiment, the step of obtaining environmental operation data of the external structure of the physical gate system, the environmental operation data including water level, gate flow, environmental temperature data and environmental humidity, further includes the following steps: Environmental operation data can also include geographic location information and weather information of the physical gate system.

[0030] The digital twin gate system can use geographic information system (GIS) technology to integrate the geographic location information of the physical gate system. The geographic location information includes the latitude and longitude coordinates of the gate, the surrounding topography, etc., which helps to accurately locate the physical gate system in the digital twin model; by accessing the meteorological data API, the digital twin gate system can obtain weather information at the location of the physical gate system, such as temperature, humidity, wind speed, precipitation, etc.; through integrated weather information and geographic location information, the digital twin gate system can monitor the status of the physical gate system in real time, and issue early warnings in extreme weather or other abnormal conditions to ensure the safe operation of the physical gate system.

[0031] In one embodiment, the step S300 of constructing a three-dimensional model according to the characteristics of the external structure and the internal operating structure of the physical gate system further includes the following steps: According to the construction design drawings and technical specifications of the physical gate system, a three-dimensional model of the electric gate system is established using BIM modeling software.

[0032] Specifically, according to the design drawings and technical specifications of the physical gate system, a three-dimensional model of the physical gate system is created in the BIM modeling software. The three-dimensional model includes the main structure, auxiliary structures and related operating devices (such as mechanical components and electrical components) of the gate; the three-dimensional model is optimized to include all necessary details, such as dimensions, material properties, connection points and operating mechanisms, to ensure that each component in the model corresponds to the actual physical gate system, and the parametric design function of the BIM software is used to set model parameters, such as material strength, weight, durability, etc., to ensure that the model can be used for subsequent performance analysis and simulation; the technical specifications and operating parameters in the construction drawings are embedded into the model to make the three-dimensional model an information-rich BIM three-dimensional model; the BIM model is integrated into the digital twin gate system to make it a part of the digital twin gate system, and combined with the data from the real-time sensing device to achieve the purpose of real-time monitoring and analysis.

[0033] In one embodiment, the step S300 of constructing a three-dimensional model according to the characteristics of the external structure and the internal operating structure of the physical gate system further includes the following steps: The internal operating structure includes hydraulic devices, electrical control devices and sensor devices.

[0034] Dynamic simulation is performed on the action of the hydraulic device, the response of the electrical control device, and the data acquisition of the sensor device to verify their performance in actual operation. The operating data of the hydraulic device and the electrical control device are integrated with the actual data collected by the sensor for real-time monitoring and analysis in the digital twin gate system.

[0035] In one embodiment, after the step S300 of establishing a three-dimensional model of the electric gate system using BIM modeling software according to the construction design drawings and technical specifications of the physical gate system, the following steps are also included: BIM modeling software is used to integrate geometric feature information, material information, service life information, and maintenance cycle information into the three-dimensional model.

[0036] In the BIM model, material properties such as material type, strength, durability and appearance characteristics can be specified for each component, which helps to select appropriate materials in subsequent construction and maintenance. The expected life, replacement cycle and maintenance requirements of the material are also added to facilitate predictive maintenance planning of the system and life cycle management of operating equipment.

[0037] See also Figure 2 In one embodiment, after step S300 of establishing a three-dimensional model of the electric gate system using BIM modeling software according to the construction design drawings and technical specifications of the physical gate system, the following steps are also included: S31: Acquire an oblique photographic image of the actual environment around the physical gate system; S32: extracting the structural contour features of the gate body from the actual environment oblique photography image around the physical gate system to obtain structural contour feature data of the physical gate plate body; S33: constructing a physical gate system model based on the structural profile feature data of the physical gate plate to obtain a three-dimensional optimization model of the physical gate system; S34: constructing a three-dimensional terrain model based on the environmental data of the physical gate system to generate a three-dimensional terrain model; S35: Import the 3D optimization model and the 3D terrain model into the UE5 editor, and adjust the material, texture, and lighting details of the 3D optimization model and the 3D terrain model; S36: Based on the UE5 editor, a digital twin scene is constructed for the three-dimensional optimization model and the three-dimensional terrain model of the physical gate system to obtain a digital twin scene of the physical gate system; S37: Perform load optimization rendering on the digital twin scene of the physical gate system to generate a digital twin optimization scene of the sluice gate.

[0038] Specifically, the actual environment image around the physical gate system can be obtained through the oblique photography camera carried by the drone or helicopter. The actual environment image is used to create a three-dimensional terrain model of the physical gate system. The obtained oblique photography image is processed to extract the structural contour features of the gate body, and the structural contour feature data of the physical gate plate (i.e., the external structure of the physical gate system) is obtained. The extracted structural contour feature data is combined with the BIM modeling software to build a three-dimensional optimization model of the physical gate system; the environmental data of the physical gate system is processed, and the three-dimensional terrain model is constructed using DEM (digital elevation model) data or other related technologies; the constructed three-dimensional optimization model and three-dimensional terrain model are imported into the UE5 editor, and the imported model is adjusted in detail in the UE5 for material, texture and lighting; based on the UE5 editor, the adjusted three-dimensional optimization model and three-dimensional terrain model are used to build a digital twin scene, and the load of the digital twin scene is optimized to ensure that the scene runs smoothly in UE5. Specifically, it can include optimizing the number of polygons of the three-dimensional model, adjusting the complexity of the material, and optimizing the lighting settings. Finally, rendering is performed to generate a digital twin optimization scene for the sluice.

[0039] In one embodiment, when the actual operation data of any operation device exceeds the operation data threshold and the corresponding operation device is determined to be in a fault state, the step S700 of the digital twin gate system issuing a maintenance reminder message includes the following steps: When the actual stress value of the detected operating device is greater than the stress threshold of the corresponding operating device, it is determined that the corresponding operating device is in a fault state; or, When the actual deformation value of the detected operating device is greater than the deformation threshold of the corresponding operating device, it is determined that the corresponding operating device is in a fault state; or, When the actual wear degree of the detected operating device is greater than the wear threshold of the corresponding operating device, it is determined that the corresponding operating device is in a fault state; or, When the detected actual vibration frequency of the operating device is greater than the vibration frequency threshold of the corresponding operating device, it is determined that the corresponding operating device is in a fault state; or, When the detected actual annual corrosion rate of the operating device is greater than the annual corrosion rate threshold of the corresponding operating device, it is determined that the corresponding operating device is in a fault state.

[0040] For example, if the strain gauge detects that the deformation of a certain operating component exceeds the deformation threshold allowed by the design (for example, the deformation threshold is 0.5mm), it means that the operating component is abnormally stressed or damaged, and the digital twin gate system should trigger an alarm and issue a maintenance reminder message. If the vibration frequency detected by the vibration sensor exceeds the vibration frequency threshold (for example, the vibration frequency threshold is 50Hz) and the duration exceeds the set time range, it means that there may be a fault in the motor or hydraulic system, and the digital twin gate system should trigger an alarm and issue a maintenance reminder message. If the temperature of a certain operating component exceeds the temperature threshold (such as the temperature threshold is 80°C), the digital twin gate system should trigger an alarm and issue a maintenance reminder message, indicating that there may be an overload or heat dissipation problem. If the electrochemical sensor detects that the corrosion rate exceeds the set corrosion rate threshold (such as the annual corrosion rate is greater than 0.1mm / year), the digital twin gate system should trigger an alarm and mark other affected operating devices in the three-dimensional model. Based on the maintenance reminder information and fault location information, the operation and maintenance personnel take corresponding maintenance measures, such as on-site inspection, repair or replacement of faulty parts, and can accurately locate the location of the fault, so as to achieve the purpose of rapid troubleshooting and repair.

[0041] In one embodiment, when the actual operation data of any operation device exceeds the operation data threshold and the corresponding operation device is determined to be in a fault state, the step S700 of the digital twin gate system issuing a maintenance reminder message includes the following steps: When the actual operating data of any operating device exceeds the operating data threshold and the corresponding operating device is determined to be in a fault state, the digital twin gate system will emit an audible and visual alarm message and / or a pop-up alarm message and / or highlight the corresponding faulty operating device in the three-dimensional model.

[0042] For example, once the digital twin gate system detects a fault, the system will issue an audible and visual alarm or a pop-up alarm to immediately attract the attention of the operator or maintenance personnel. The system can also issue a pop-up alarm through the computer system or other display devices of the control center to provide specific information about the faulty component and possible causes of the fault; in the three-dimensional model of the digital twin gate system, the faulty component will be highlighted, and maintenance personnel can quickly locate the fault location based on the highlighted faulty component and abnormal records, so as to quickly formulate a maintenance plan and repair the fault; in the digital twin gate system, the abnormal location will display the abnormal record, which is convenient for maintenance personnel to formulate maintenance plans in the system and improve the safety of the system.

[0043] See also Figure 3 In one embodiment, when the actual operation data of any operation device exceeds the operation data threshold and the corresponding operation device is determined to be in a fault state, the digital twin gate system issues a maintenance reminder message after step S700, and further includes the following steps: S71: Obtain historical operation data of the physical gate system; S72: predicting the future operation status of the physical gate system by analyzing the operation rules of historical operation data; S73: Determine the operating devices that need to be checked within a preset time.

[0044] The digital twin gate system will collect historical operating data of the physical gate system. The historical operating data includes information such as past water level, gate flow, ambient temperature and humidity, as well as actual operating data such as stress or deformation or wear or vibration frequency or temperature or annual corrosion rate of the operating device in the past. By analyzing historical operating data, it can identify operating patterns and potential failure modes, and predict possible trends of failures. Based on the prediction results, the system can determine the operating devices that need to be checked within a preset time, which helps to formulate maintenance plans in advance, reduce potential failures, maximize the use value of equipment, and reduce losses caused by downtime of the digital twin gate system.

[0045] In one embodiment, when the actual operation data of any operation device exceeds the operation data threshold value and the corresponding operation device is determined to be in a fault state, the digital twin gate system further includes the following steps after step S700 of issuing a maintenance reminder message: The digital twin gate system is connected to other water conservancy-related data in the region through a standardized API (Application Programming Interface) interface.

[0046] Select a standardized API interface, set the data format according to the API requirements, upload the integrated data in the digital twin gate system to the storage medium, and use the unified API interface to connect with other water conservancy-related data in the region to achieve interaction. Unified data formats and interfaces can greatly reduce the workload of developers and improve the stability and maintainability of the system.

[0047] The technical solution of the present invention obtains the actual operating data of the physical gate system, which includes at least an external structure and an internal operating structure; in each operating device of the internal operating structure of the physical gate system, at least one sensor device is correspondingly arranged to collect the actual operating data to form a sensor monitoring network; a three-dimensional model is constructed according to the characteristics of the external structure and the internal operating structure of the physical gate system; a digital twin gate system is established according to the three-dimensional model and the sensor monitoring network to form a mapping relationship between the operating device and the three-dimensional model; the operating data threshold of each operating device is obtained respectively; the actual operating data of each operating device is compared with the operating data threshold separately; when the actual operating data of any operating device exceeds the operating data threshold, it is determined that the corresponding operating device is in a fault state, and the digital twin gate system issues a maintenance reminder message. By obtaining actual operation data from the external structure and internal operation structure of the physical gate system, and using modeling software to build a three-dimensional model of the physical gate system, by setting sensors in each key operation device, a comprehensive sensor monitoring network is constructed, and the constructed three-dimensional model is combined with the sensor monitoring network to form a mapping relationship between the operation device and the three-dimensional model, and a digital twin gate system is created, so that the digital twin gate system can reflect the status of the physical gate in real time; by using the digital twin gate system, the real-time operation status of the physical gate system can be fully reflected; operation data thresholds are set for each operation device, which are determined based on the technical specifications and historical operation data of the equipment to determine whether the equipment is operating normally; the actual operation data collected by the sensor device is compared with the preset threshold. If the data of any operation device exceeds the threshold, the system will determine that the operation device is in a fault state; once the system detects a fault state, the digital twin gate system will convey it to the operation and maintenance personnel by issuing a maintenance reminder message; due to the mapping relationship in the digital twin gate system, the exact location and related components of the fault can be quickly located, thereby speeding up the fault repair, which has the advantages of reducing the workload of troubleshooting and improving the troubleshooting speed.
