[0034] Example 1

[0035] According to an embodiment of the present invention, an embodiment of a method for monitoring environmental information of a power transmission tunnel is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0036] Figure 1 is a flow chart of a method for monitoring environmental information of a power transmission tunnel according to an embodiment of the present invention. Figure 1 As shown, the method may include the following steps:

[0037] Step S101, obtaining environmental information in a power transmission tunnel.

[0038] In the technical solution provided in the above step S101 of the present invention, the environmental information in the transmission tunnel is used to at least indicate the temperature, humidity and safety status of the transmission tunnel, etc. This is only an illustrative example and does not limit the environmental information in the transmission tunnel.

[0039] In this embodiment, a variety of high-precision sensors are deployed in the transmission tunnel, such as temperature sensors, humidity sensors, oxygen sensors, pressure sensors, etc. Various sensors deployed in the transmission tunnel can detect and obtain environmental data in the transmission tunnel, and the obtained environmental data can be used as environmental information in the transmission tunnel.

[0040] Step S102: synchronously input the environmental information into the digital twin model of the transmission tunnel, and control the digital twin model to run under the environmental information.

[0041] In the technical solution provided in the above step S102 of the present invention, the digital twin model is obtained by pre-modeling the power transmission tunnel with digital twin technology. The digital twin model serves as a physical entity mirror image of the power transmission tunnel in a virtual environment and can reflect the operating status of the power transmission tunnel in real time.

[0042] In this embodiment, after the environmental information in the transmission tunnel is acquired through step S101, the acquired environmental information can be synchronously input into the digital twin model of the transmission tunnel, and the digital twin model can operate according to the environmental information to realize the sharing of environmental information between the transmission tunnel and the digital twin model, so that the digital twin model can reflect the actual operating status in the transmission tunnel in real time.

[0043] Optionally, since there may be abnormal data or duplicate data in the environmental data collected by the sensor, in order to further improve the accuracy of the environmental data input into the digital twin model, the environmental data can be preprocessed, and then the processed environmental data can be input into the digital twin model, wherein the preprocessing at least includes outlier detection and processing of the environmental data to remove noise in the environmental data, and data format standardization operations on the environmental data after noise removal to improve the accuracy of the environmental data input into the digital twin model.

[0044] Step S103, determining the fault prediction result of the environmental information according to the operating status of the digital twin model and the simulation calculation results corresponding to the environmental information.

[0045] In the technical solution provided in the above step S103 of the present invention, the operating status of the digital twin model is used to at least reflect the operating status of the transmission tunnel, the simulation result data is used to indicate the normal operating status of the transmission tunnel under the environmental information, and the fault prediction result is used to indicate whether there is an abnormal risk in the environmental information in the transmission tunnel.

[0046] In this embodiment, the operating status of the transmission tunnel under different environmental information is modeled and simulated in advance, and the normal operating status of the transmission tunnel under different environmental information is obtained. Based on this, the simulation calculation results obtained under different environmental information can be used as a reference to compare the operating status of the digital twin model of the transmission tunnel under the corresponding environmental information, so as to determine whether there is an abnormal risk in the environmental information in the transmission tunnel.

[0047] For example, the operating state of the digital twin model under the current environmental information can be matched with the operating state of the power transmission tunnel under the corresponding environmental information obtained by simulation modeling to obtain a matching result, wherein the matching result is used to at least indicate the matching degree between the operating state of the digital twin model and the operating state of the power transmission tunnel obtained by simulation modeling. Since the operating state of the digital twin model is used to display the operating state of the power transmission tunnel under the currently acquired environmental information, if the matching degree is lower than the matching degree threshold, it is determined that the environmental information in the power transmission tunnel may have an abnormal risk. On the contrary, if the matching degree is higher than the matching degree threshold, it means that the operating state of the power transmission tunnel displayed by the digital twin model under the currently acquired environmental information has a high matching degree with the normal operating state of the power transmission tunnel displayed by the simulation modeling result under the corresponding environmental information. In this case, it can be determined that the environmental information in the transmission tunnel is normal, that is, there is no abnormal risk in the environmental information in the transmission tunnel.

[0048] Step S104: in response to the fault prediction result indicating that the environmental information in the transmission tunnel has an abnormal risk, triggering an alarm message.

[0049] In the technical solution provided in the above step S104 of the present invention, if the fault prediction result determined according to step S103 indicates that there is an abnormal risk in the environmental information in the transmission tunnel, an alarm message can be triggered, which is used to prompt maintenance operations on the environmental information in the transmission tunnel.

[0050] Optionally, the alarm information can be sent to relevant managers and emergency response teams in real time through preset communication channels to ensure that relevant managers can initiate emergency plans in a timely manner and maintain the cable lines.

[0051] Optionally, the digital twin model and the operating status of the digital twin model can be visualized, and the operation and maintenance personnel can view and adjust the operation and maintenance strategy of the transmission tunnel in real time to improve the operation and maintenance efficiency of the transmission tunnel.

[0052] In the above steps S101 to S104 of the present application, a digital twin model of the transmission tunnel is constructed in advance. Since the digital twin model is a mirror model corresponding to the transmission tunnel in the virtual environment, it can map the operating status of the transmission tunnel in real time. Based on this, after obtaining the environmental information in the transmission tunnel, the environmental information in the transmission tunnel can be synchronously input into the digital twin model of the transmission tunnel to realize the sharing of environmental information between the transmission tunnel and the digital twin model, and then by observing the operating status of the digital twin model and combining the normal operating status of the transmission tunnel under the current environmental information obtained in advance through simulation modeling, the digital twin model can be used to generate a real-time ... By using digital twin technology, it is possible to determine in real time whether there is an abnormal risk in the environmental information in the transmission tunnel, and then issue a timely alarm when there is an abnormal risk in the environmental information in the transmission tunnel, effectively avoiding the situation where the cable line in the transmission tunnel fails to be monitored in time, thereby affecting the safety and reliability of the power grid. That is, the digital twin technology realizes comprehensive monitoring of the environmental information of the cable line and fault warning, thereby reducing the impact of abnormal environmental information in the transmission tunnel on the cable line failure, and solving the technical problem of being unable to effectively monitor the environmental information in the transmission tunnel.

[0053] The above method of this embodiment is further introduced below.

[0054] As an optional implementation method, step S103 determines the fault prediction result of the environmental information according to the operating state of the digital twin model and the simulation calculation results corresponding to the environmental information, including: based on the environmental information, determining the simulation result data corresponding to the environmental information from the simulation result data of the environmental information samples corresponding to different environmental working conditions; comparing the operating state of the digital twin model with the normal operating state of the transmission tunnel indicated by the simulation calculation results to obtain a comparison result; in response to the comparison result indicating that the operating state of the digital twin model does not match the normal operating state of the transmission tunnel indicated by the simulation calculation results, determining that the fault detection result is that there is an abnormal risk in the environmental information in the transmission tunnel.

[0055] In this embodiment, the normal operating state of the transmission tunnel under the environmental information samples corresponding to different environmental conditions is calculated in advance by means of simulation modeling, that is, the simulation calculation results can be used to represent the normal operating state of the transmission tunnel under different environmental conditions. Based on this, according to the acquired environmental information, environmental information samples matching the current environmental information are selected from the environmental information samples corresponding to different environmental conditions, and the simulation calculation results corresponding to the selected environmental information samples are used as a reference to compare with the operating state of the digital twin model of the transmission tunnel under the current environmental information to obtain a comparison result. Among them, the comparison result is used to indicate whether the operating state of the transmission tunnel represented by the digital twin model is consistent with the normal operating state of the transmission tunnel represented by the simulation calculation results under the same environmental conditions.

[0056] Optionally, if the comparison result indicates that the operating state of the power transmission tunnel represented by the digital twin model does not match the normal operating state of the power transmission tunnel represented by the simulation calculation result, the fault detection result is determined to be that there is an abnormal risk in the environmental information within the power transmission tunnel.

[0057] Optionally, if the comparison result indicates that the operating state of the power transmission tunnel represented by the digital twin model matches the normal operating state of the power transmission tunnel represented by the simulation calculation result, the fault detection result is determined to be that the environmental information in the power transmission tunnel is normal.

[0058] In this step, the normal operating status of the transmission tunnel under different environmental conditions obtained by simulation modeling is used as a reference, and then combined with the operating status of the digital twin model to determine whether there is a fault risk in the environmental information in the transmission tunnel. Real-time monitoring and fault warning of environmental information in the transmission tunnel are realized without the need for manual patrols, which improves the monitoring efficiency and accuracy of environmental information in the transmission tunnel.

[0059] As an optional implementation method, a method for monitoring environmental information of a transmission tunnel includes: in response to the existence of abnormal risks in the environmental information in the transmission tunnel, updating an operation and maintenance strategy for the environmental information based on the operating status of a digital twin model, wherein the operation and maintenance strategy is used to indicate rules for adjusting the environmental information in the transmission tunnel.

[0060] In this embodiment, if there is an abnormal risk in the environmental information in the transmission tunnel, the operation and maintenance strategy of the environmental information of the transmission tunnel can be automatically updated, and the updated operation and maintenance strategy can be sent to relevant operation and maintenance personnel through a preset communication channel, so that the relevant operation and maintenance personnel can adjust the environmental information in the transmission tunnel in time according to the updated operation and maintenance strategy.

[0061] Optionally, the digital twin model of the transmission tunnel and the operating status of the digital twin model of the transmission tunnel can be displayed in the visualization platform. Based on this, after the system automatically updates the operation and maintenance strategy of the environmental information of the transmission tunnel, the updated operation and maintenance strategy can be synchronously displayed in the visualization platform, and relevant operation and maintenance personnel can adjust the operation and maintenance strategy displayed in the visualization platform to make the operation and maintenance strategy more in line with the actual situation.

[0062] In the above steps, when abnormal environmental information in the transmission tunnel is detected, the operation and maintenance strategy of the environmental information can be automatically updated, which improves the intelligence and adaptability of the system, reduces the need for manual intervention, and improves the efficiency and reliability of the system; the updated operation and maintenance strategy is synchronously displayed on the visualization platform, so that relevant operation and maintenance personnel can intuitively understand the system status and operation and maintenance strategy, facilitate correct adjustments and decisions, and improve the visualization and operability of the system.

[0063] As an optional implementation method, the method for monitoring environmental information of a transmission tunnel also includes: screening out environmental information samples corresponding to different environmental conditions from the historical environmental information of the transmission tunnel; simulating and modeling the environment in the transmission tunnel based on the environmental information samples corresponding to the different environmental conditions, and obtaining simulation result data corresponding to the environmental information samples.

[0064] In this embodiment, since the historical environmental information of the transmission tunnel includes environmental information samples corresponding to different environmental conditions, based on this, environmental information samples corresponding to different environmental conditions can be screened out from the historical environmental information of the transmission tunnel, and then through modeling and simulation technology, according to the environmental information samples corresponding to different environmental conditions, the normal operating state in the transmission tunnel is simulated and modeled, and simulation result data corresponding to the environmental information samples are obtained, wherein the simulation result data can be used to characterize the normal operating state of the transmission tunnel under different environmental conditions.

[0065] Optionally, after obtaining the simulation result data, the simulation result data can be used as a reference to determine whether the operating status of the digital twin model of the transmission tunnel is normal under the corresponding environmental conditions, and then determine whether there is any abnormal risk in the environmental information of the transmission tunnel.

[0066] As an optional implementation method, the method for monitoring the environmental information of a transmission tunnel also includes: based on the historical environmental information of the transmission tunnel, simulating and calculating various types of faults in the transmission tunnel to obtain fault data corresponding to each type of fault, wherein the fault data is used to at least indicate the fault type of the corresponding fault; and storing the fault data corresponding to each type of fault in a database corresponding to the digital twin model.

[0067] In this embodiment, the historical environmental information of the transmission tunnel is used as an information sample to set various types of faults that may occur in the transmission tunnel, such as poor contact of electrical equipment, wear of cable lines, increased dielectric loss caused by moisture in cable lines, and material defects. These are only illustrative examples and do not limit the possible fault modes that may occur in the transmission tunnel.

[0068] Optionally, after setting various types of faults that may occur in the transmission tunnel, the faults corresponding to these fault types can be simulated and calculated through modeling and simulation technology to simulate the impact and diffusion process of various faults in the transmission tunnel. Through simulation calculation, fault data corresponding to various faults can be obtained, including the location of the fault, the scope of impact, the duration and other information.

[0069] Optionally, after obtaining the fault data, the fault data can be stored in a database corresponding to the digital twin model. Then, when the operating state of the digital twin model of the transmission tunnel is abnormal, fault data matching the abnormal operating state can be obtained from the database to determine the fault information of the fault that may occur in the transmission tunnel, thereby achieving the purpose of effectively warning of faults in the transmission tunnel.

[0070] In this step, the possible fault types that may occur in the transmission tunnel are modeled and simulated through simulation modeling technology, and the fault data corresponding to each type of fault is obtained. The obtained fault data is then used as a reference. When the operating status of the digital twin model of the transmission tunnel is abnormal, the fault type of the possible fault in the transmission tunnel can be quickly determined from the fault data, thereby achieving the technical effect of timely and effective early warning of faults in the transmission tunnel.

[0071] As an optional implementation method, the environmental monitoring method for a transmission tunnel also includes: in response to an abnormality in the operating state of the digital twin model, obtaining fault data corresponding to the environmental information in which the digital twin model operates from a database corresponding to the digital twin model; inputting the fault data into the digital twin model, and controlling the digital twin model to display the fault type corresponding to the fault data.

[0072] In this embodiment, various possible fault conditions in the transmission tunnel are simulated in advance through the historical environmental information of the transmission tunnel, and the fault data is stored in the database of the digital twin model. Based on this, when the operating status of the transmission tunnel is detected by the digital twin model, if the operating status of the digital twin model is found to be abnormal, the user can quickly retrieve the fault data corresponding to the abnormal operating status from the database corresponding to the digital twin model, and input the fault data into the digital twin model for fault display, thereby realizing real-time early warning and diagnosis of faults in the transmission tunnel.

[0073] As an optional implementation method, in response to a fault prediction result indicating that the environmental information in the transmission tunnel has an abnormal risk, triggering an alarm message includes: generating an alarm message in response to a fault prediction result indicating that the environmental information in the transmission tunnel has an abnormal risk; and controlling the target information transmission channel to publish the alarm message.

[0074] In this embodiment, if the fault prediction result indicates that there is a risk in the environmental information in the transmission tunnel, an alarm message can be automatically generated and released through a target information transmission channel so that relevant operation and maintenance management personnel can receive the alarm information in time and adjust the environmental information in the transmission tunnel, wherein the target information transmission channel can be a preset communication channel.

[0075] For example, after the alarm information is generated, it can be promptly transmitted to relevant managers and emergency response teams through preset communication channels.

[0076] As an optional implementation method, the environmental monitoring information of the transmission tunnel also includes: obtaining point cloud data and status monitoring data of the transmission tunnel, wherein the status monitoring data is used to at least indicate the operating status of the transmission tunnel; based on the point cloud data, constructing a three-dimensional model of the transmission tunnel; and integrating the three-dimensional model with the status monitoring data to obtain a digital twin model of the transmission tunnel.

[0077] In this embodiment, the construction of the digital twin model of the transmission tunnel includes two parts: three-dimensional modeling of the transmission tunnel and twin modeling. Among them, the three-dimensional modeling of the transmission tunnel can be obtained by establishing a three-dimensional model through the point cloud data of the transmission tunnel, and the twin modeling can be obtained by combining the three-dimensional model with the status monitoring data of the transmission tunnel monitored in real time.

[0078] Optionally, the point cloud data of the transmission tunnel can be obtained by laser scanning. For example, by scanning underground projects such as tunnels with laser scanning equipment, the three-dimensional point cloud data of underground cable lines can be obtained. Among them, the three-dimensional point cloud data of the transmission tunnel can be used to at least represent the structural information, spatial layout and connection method of the transmission tunnel. The status monitoring data of the transmission tunnel can be obtained by sensors. For example, various sensors can be deployed at key positions of the transmission tunnel to obtain the line parameters of the transmission tunnel, the environmental parameters in the transmission tunnel, etc. Among them, the line parameters are used to at least represent the size information of various cable lines laid in the transmission tunnel and the current, voltage, etc. during operation. The environmental parameters in the transmission tunnel are used to at least represent the environmental humidity and temperature in the transmission tunnel. This is only an illustrative example. The characteristic information of the transmission tunnel can also include other information, which is not given one by one here.

[0079] Optionally, after acquiring the characteristic information of the power transmission tunnel, since the data included in the characteristic information of the power transmission tunnel may contain abnormal values ​​or repeated values, in this case, in order to ensure data quality and to perform accurate data analysis and modeling, the acquired raw data may be preprocessed.

[0080] Optionally, preprocessing may include an outlier detection and processing process, for example, detecting outliers in characteristic data and deleting the detected outliers to remove noise data in the characteristic information. This is only an illustrative example and does not limit the method of removing noise in the characteristic information of the transmission tunnel.

[0081] Optionally, after removing noise data from the characteristic information of the power transmission tunnel, a standardization operation may be performed on the characteristic information after the noise is removed, so as to convert the data into a unified data format, so as to facilitate subsequent data analysis.

[0082] Optionally, after preprocessing the characteristic information of the transmission tunnel, a digital twin model of the transmission tunnel can be constructed based on the preprocessed characteristic information, wherein the construction of the digital twin model of the transmission tunnel includes three-dimensional modeling and twin modeling. Among them, three-dimensional modeling can use three-dimensional modeling technology to process the preprocessed three-dimensional point cloud data to construct a high-precision, high-fidelity three-dimensional model of the transmission tunnel and its ancillary settings, wherein the three-dimensional model can truly reflect the physical characteristics and spatial layout of the transmission tunnel. Twin modeling can be obtained by combining the three-dimensional model of the transmission tunnel with the preprocessed status monitoring data to obtain a digital twin model of the transmission tunnel, wherein the digital twin model can truly reflect information such as the operating status and environmental changes of the transmission tunnel.

[0083] As an optional implementation, the environmental monitoring method for a transmission tunnel also includes: in response to an update of environmental information in the transmission tunnel, updating components in a digital twin model of the transmission tunnel that are associated with the updated environmental information to obtain an updated digital twin model; and monitoring the environmental information of the transmission tunnel based on the updated digital twin model.

[0084] In this embodiment, in order to enable the digital twin model of the transmission tunnel to accurately reflect the actual situation in the transmission tunnel, in response to the update of the environmental information in the transmission tunnel, the components associated with the updated environmental information in the digital twin model of the transmission tunnel can be updated to obtain an updated digital twin model; then, based on the updated digital twin model, the transmission tunnel is monitored for faults to ensure the accuracy of real-time fault warning monitoring of the environmental information in the transmission tunnel through the digital twin model.

[0085] In this step, after the environmental information in the transmission tunnel is updated, the digital twin model of the transmission tunnel can be updated according to the updated environmental information in the transmission tunnel, so as to iteratively optimize the digital twin model of the transmission tunnel, so that the iterative digital twin model can accurately reflect the actual operating conditions of the transmission tunnel, thereby improving the accuracy of fault warning of environmental information in the transmission tunnel through the digital twin model, and ensuring the long-term stability and reliability of the early warning system.

[0086] Optionally, the digital twin model can be used to realize real-time monitoring of environmental information in the transmission tunnel. By comparing with the simulation result data, it can be determined in real time whether there are any abnormalities in the environmental information in the transmission tunnel. When there are abnormalities, alarm information is automatically generated and released through a preset target information transmission channel, so that relevant operation and maintenance personnel can respond to the fault quickly and handle it in time to ensure the reliable operation of the transmission tunnel.

[0087] Optionally, the environmental monitoring method of the power transmission tunnel can be implemented by a digital twin model monitoring system.

[0088] In the method for monitoring the environmental information of a transmission tunnel proposed in the present invention, digitization is used as a means to realize efficient and intelligent monitoring of the environmental information in the transmission tunnel and high-accuracy fault diagnosis. By constructing a digital twin model, acquiring real-time sensor data, and performing modeling simulation and fault monitoring and early warning, comprehensive monitoring and early warning of the environmental information in the transmission tunnel are realized. At the same time, by iteratively optimizing the digital twin model and improving the prediction accuracy, the long-term stability and reliability of the early warning system are ensured.

[0089] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0090] At present, with the rapid development of the power industry, transmission tunnels, as a core component of the power grid, are crucial to the safe and stable operation of power supply. However, transmission tunnels are susceptible to a variety of factors during operation, including temperature, humidity, external damage, equipment aging, and load fluctuations, which may cause cable line failures and thus affect the safety and reliability of the power grid.

[0091] In the related technology, when monitoring the various influencing factors of the transmission tunnel, it is usually dependent on manual inspections or timed data collection, which cannot achieve real-time monitoring, resulting in a failure to respond quickly in emergencies. There is a technical problem that the influencing factors of the transmission tunnel cannot be monitored and warned in real time.

[0092] However, an embodiment of the present invention provides a monitoring and early warning method for environmental information of a power transmission tunnel based on digital twin technology. By performing digital twin modeling on the power transmission tunnel, a digital twin model corresponding to the power transmission tunnel is obtained, and then the environmental information in the power transmission tunnel is obtained, and data is shared with the digital twin model; the operation status of the power transmission tunnel is monitored by the digital twin model, and combined with the simulation calculation data, the cable line is detected for faults, wherein the simulation calculation data is used to indicate the operation status data of the power transmission tunnel under different environmental conditions obtained in advance through simulation modeling; when the environmental information of the power transmission tunnel is monitored to have an abnormal risk, an alarm message can be triggered, wherein the alarm message can be sent to relevant managers and emergency response teams in real time through a preset communication channel, and the emergency plan is automatically started at the same time, to ensure that when the environmental information of the power transmission tunnel does not have a significant impact on the operation status of the power transmission tunnel, the environment in the power transmission tunnel is maintained in time to ensure the reliable operation of the power transmission tunnel. That is, through digital twin technology, comprehensive monitoring of environmental information in the transmission tunnel and fault warning are achieved, which reduces the situation where the transmission tunnel cannot operate normally due to abnormal environmental information, and solves the technical problem of being unable to monitor the environmental information in the transmission tunnel in real time.

[0093] Next, we will give a brief introduction to digital twin technology.

[0094] Digital twin technology originated in the manufacturing industry. Its core is to build an accurate mapping of physical entities in virtual space, so as to realize real-time monitoring, simulation prediction and optimization control of the operating status of physical entities. With the rapid development of technologies such as the Internet of Things, big data, and artificial intelligence, digital twin technology is increasingly used in the power industry, especially in the monitoring and management of multiple environmental variables in transmission tunnels. Although digital twin technology has shown significant advantages and broad application prospects, it still faces several challenges and limitations in the actual process. For example, at present, the application of digital twin technology in the electrical industry is mainly concentrated in scene display or substation modeling, while the monitoring and application examples of key parameters of the cable body are relatively scarce.

[0095] Optionally, in order to ensure the accuracy of environmental information monitored in the transmission tunnel through the digital twin model, the following issues need to be improved simultaneously.

[0096] Sensor performance issues: During long-term operation, sensors in transmission tunnels may experience drift and reduced accuracy, resulting in errors in the collected data. If these errors are not effectively corrected, they will directly affect the accuracy and reliability of the digital twin model. Therefore, sensors need to be calibrated and maintained regularly to ensure data accuracy.

[0097] Environmental interference: The environment of power transmission tunnels is complex and changeable. Factors such as electromagnetic interference, temperature and humidity changes may affect the normal operation of sensors, thereby reducing the accuracy of data. In order to reduce the impact of environmental interference on sensors, appropriate shielding and protection measures should be taken to improve the anti-interference ability of sensors.

[0098] Data synchronization problem: There may be a time difference in data collection and transmission between different sensors, which will lead to data synchronization problems and affect the real-time analysis of the operating status of the cable line. To solve this problem, it is necessary to optimize the data collection and transmission system to ensure that the data between the sensors can be synchronized in real time.

[0099] Insufficient real-time monitoring: Currently, the method of relying on manual inspection or timed data collection cannot achieve real-time monitoring. This may lead to an inability to respond quickly in emergencies. Therefore, a real-time data collection and transmission system should be developed to improve the real-time monitoring and response speed.

[0100] Limited fault diagnosis and decision support capabilities: The current digital twin monitoring system may not be able to accurately diagnose and predict all types of faults, and some complex faults still require manual intervention. At the same time, the system may still be insufficient in providing decision support for operation and maintenance personnel and cannot completely replace the manual decision-making process. In order to improve the system's fault diagnosis and decision support capabilities, more advanced artificial intelligence and machine learning algorithms should be introduced to improve the accuracy of fault diagnosis and the scientific nature of decision-making.

[0101] Optionally, in view of the limitations of the above-mentioned digital twin model in the actual application of environmental monitoring in transmission tunnels, the present invention proposes a corresponding improvement strategy, which aims to further improve the application effect and value of digital twin technology in the electrical industry by optimizing sensor performance, reducing environmental interference, solving data synchronization problems, improving real-time monitoring, and enhancing fault diagnosis and decision-making support capabilities.

[0102] Next, the monitoring method of environmental information in the transmission tunnel based on the digital twin model is further introduced.

[0103] Figure 2 is a flow chart of a method for monitoring environmental information in a power transmission tunnel based on a digital twin model according to an embodiment of the present invention, such as Figure 2 As shown, the method comprises the following steps:

[0104] Step S201: perform digital twin modeling on the power transmission tunnel to obtain a digital twin model of the power transmission tunnel.

[0105] In this embodiment, the digital twin model is a physical entity mirror image of the transmission tunnel, which can reflect the operating status in the transmission tunnel in real time.

[0106] Optionally, based on the core requirements of digital twin technology, the operation history data updated by the physical model and sensors is used to integrate complex simulation processes involving multiple disciplines, multiple physical quantities, multiple scales and multiple probabilities to accurately map the entire life cycle of the physical equipment in a virtual environment. This full life cycle concept covers the complete cycle from the design and development, production and manufacturing, operation and service, maintenance and recycling of the physical equipment.

[0107] Optionally, Figure 3 is a schematic diagram of a generation process of a digital twin of a power transmission tunnel according to an embodiment of the present invention, such as Figure 3 As shown, when generating the digital twin of the transmission tunnel, it is mainly completed through the following process: extracting point cloud tunnel environment attribute data, preprocessing attribute data, collecting spatial data, collecting texture data, and generating the digital twin of the transmission tunnel.

[0108] For example, the present invention has carried out detailed replica modeling work based on the actual scenario of multiple environmental variables in high-speed transmission tunnels. The process is subdivided into two main parts: external scene and internal scene. As an example, the internal scene mainly includes key equipment such as transmission lines and high-voltage cable lines' depth monitoring sensor devices and grounding boxes, while the external scene mainly includes external factors such as temperature, humidity, oxygen, pressure, geological environment, and human interference in the transmission tunnel. This is only an illustrative example.

[0109] In the modeling practice, professional software platforms such as 3D modeling software Autodesk 3ds Max and Autodesk Maya and texture drawing software Substance Painter were used. These platforms can perform high-precision digital 3D twin modeling of multiple environmental variables of the transmission tunnel based on CAD drawings or model data in obj format. In particular, a 1:1 ratio was used to restore the digital twin modeling, thereby generating a digital twin that corresponds one-to-one with the entity. Figure 4 is a schematic diagram of details of generating a digital twin of a power transmission line in a power transmission tunnel according to an embodiment of the present invention, such as Figure 4 As shown, the tunnel includes cables, channels, brackets and equipment, etc., which are used to simulate all equipment in the transmission tunnel. Figure 5 is a schematic diagram of a local twin of a transmission line according to an embodiment of the present invention. Figure 4 and Figure 5 The application effect and value of digital twin technology in transmission tunnel modeling are intuitively presented.

[0110] Step S202: Acquire real-time environmental data in the transmission tunnel and share the data with the digital twin.

[0111] In this embodiment, in order to accurately obtain real-time environmental data in the transmission tunnel, a variety of high-precision sensors are used, such as temperature sensors, humidity sensors, oxygen sensors, etc.

[0112] Temperature sensors are mainly used to measure temperature changes inside power transmission tunnels, record temperature changes inside tunnels in real time, and transmit data to computer systems for analysis and recording. When the temperature inside the tunnel exceeds the expected range, the system will automatically sound an alarm and take control measures to ensure that the ambient temperature inside the tunnel is safe and stable.

[0113] The humidity sensor measures the air humidity in the tunnel and monitors the humidity changes and trends of the air inside the tunnel. When the humidity exceeds the normal range, an alarm will be issued and corresponding control measures will be taken to ensure that the air humidity in the tunnel is stable and safe.

[0114] Oxygen sensors monitor the oxygen content in the tunnel to ensure the safety of the gas environment in the tunnel. When the oxygen content is lower than the safe range, an alarm will be issued to the system and control measures will be taken to ensure the safety of personnel in the tunnel and the normal operation of equipment. Smoke sensors detect signs of smoke or flames in the tunnel. When the sensor detects smoke or flames, it will immediately issue an alarm to the system and take corresponding control measures to ensure the safety of passengers and facilities in the tunnel. Gas detection sensors monitor the concentration of harmful gases (such as carbon monoxide, sulfur dioxide, methane, etc.) in the tunnel. These sensors can sense changes in gas concentration in real time and issue an alarm when the concentration exceeds the standard to prevent harmful gases from causing damage to human health or equipment. Wind speed and direction sensors monitor the wind speed and direction in the tunnel, which is of great significance for evaluating the ventilation conditions in the tunnel and preventing the accumulation of pollutants.

[0115] Optionally, a monitoring module is deployed at the site of the environmental information monitoring project of the transmission tunnel. The module not only has the ability to detect and record the environmental information in the transmission tunnel in real time, but also can share this data to the digital twin in real time. Figure 6 It is a schematic diagram of feedback of simulation results of a high-voltage cable line affected by multiple factors according to an embodiment of the present invention.

[0116] In this step, not only comprehensive and real-time monitoring of multiple environmental variables of the transmission tunnel is achieved, but also the digital twin can accurately and real-time reflect the actual status of the physical line. This provides a solid data foundation for subsequent data analysis, fault warning and decision support, and also provides a strong technical guarantee for the safe and efficient operation of the transmission tunnel.

[0117] Step S203, modeling and simulating the environmental information in the transmission tunnel, calculating the operating status of the transmission tunnel under different environmental conditions, forming simulation calculation data, and integrating the simulation calculation data with the digital twin.

[0118] In this embodiment, simulation technology is used to comprehensively model and simulate the environmental variables in the transmission tunnel. The model can accurately simulate the operating status of the transmission tunnel under different environmental conditions, and generate a series of high-precision simulation calculation data through algorithm analysis calculation results. This process pays special attention to the types of defects that may occur in the cable lines in the transmission tunnel, such as poor contact, cable wear, increased dielectric loss caused by moisture, and material defects. Through meticulous simulation analysis, the impact of these defects on the operating status of the transmission tunnel is recorded, and strictly compared with the simulation results under normal working conditions.

[0119] Furthermore, the operating status of the transmission tunnel under normal operation and typical fault conditions is compared. In this comparison process, the influence of different load conditions and environmental conditions on the operating status of the transmission tunnel is fully considered, and corresponding boundary conditions and fault conditions are set according to common fault types to ensure the comprehensiveness and accuracy of the simulation data.

[0120] In order to give full play to the functions of digital twins, the above-mentioned simulation calculation data is deeply integrated with the digital twin. As a mirror image of a physical entity in a virtual environment, the digital twin can reflect the operating status of the physical entity in real time. However, the digital twins in the prior art are mainly limited to effect display. By integrating simulation calculation data, the present invention enables the digital twin to not only display the 3D model of the transmission tunnel, but also reflect the simulation results under different state conditions in real time, thereby realizing real-time monitoring and early warning of environmental information in the transmission tunnel.

[0121] Optionally, based on historical experience and pre-modeling simulation, a comprehensive modeling of various faults occurring in multiple environmental variables in the transmission tunnel is performed, and at the same time, equipment simulation calculations are performed when there is no fault as control group data. These simulation calculation data are stored as the data basis in the computer on which the digital twin is established. On the digital twin interface, users can call the above database in real time and display the results of a certain set of data retrieved. The timing of the call depends on the judgment of the real-time monitoring results of the physical entity of the equipment. When an abnormality is found in the depth of the cable line in the transmission tunnel, the user can quickly retrieve the set of simulation calculation data corresponding to the fault from the database and display the results on the digital twin to achieve real-time fault warning and diagnosis.

[0122] In this step, by integrating modeling and simulation of multiple environmental variables in the transmission tunnel with digital twin technology, the accuracy and real-time monitoring of the environment in the transmission tunnel are significantly improved, providing a strong guarantee for the safe operation of the power project.

[0123] Step S204: monitor the operating status of the digital twin model of the transmission tunnel, and perform fault monitoring and early warning on the environmental information of the transmission tunnel based on real-time monitoring data and simulation calculation data.

[0124] In this embodiment, digital twin technology is used to construct a digital twin of multiple environmental variables of the transmission tunnel. The digital twin can map and mirror the operating status of the physical entity, and realize comprehensive monitoring of multiple environmental variables of the transmission tunnel. By matching and comparing real-time monitoring data and simulation calculation data, it is possible to accurately determine whether there are any abnormalities in the environmental information in the transmission tunnel, and to issue an early warning for abnormal environmental information based on the comparison results. After the early warning information is released, it can be sent to relevant managers and emergency response teams in real time through preset communication channels, and the emergency plan can be automatically activated to ensure timely and effective response measures.

[0125] Optionally, Figure 7 is a schematic diagram of a digital platform for monitoring multiple environmental variables in a transmission tunnel according to an embodiment of the present invention. Figure 7 As shown in Figure 2, the digital platform can visualize the environmental information of the transmission tunnel, such as Figure 7 As shown, the environmental information includes the water level value, door status, temperature, and various gas contents in the tunnel.

[0126] Furthermore, we conducted an in-depth comparative analysis of the real-time monitoring data and the simulation calculation data of the transmission tunnel multi-environmental variables under abnormal conditions. This comparative analysis not only improves the accuracy of fault detection, but also helps us take corresponding measures in time to prevent the fault from further expanding, especially for faults such as abnormal temperature rise in the transmission tunnel multi-environmental variables.

[0127] Step S205: iteratively optimize the digital twin model according to the warning effect and the actual changes in the transmission tunnel.

[0128] In this embodiment, iterative optimization of the digital twin model can improve prediction accuracy and ensure the long-term stability and reliability of the early warning system.
