[0016] Hereinafter, the technical solutions in the present application will be described clearly and completely with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. It should be understood that the present application is not limited by the example embodiments described herein. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application. In addition, it should be noted that, for convenience of description, only parts related to the present application are shown in the drawings, rather than all parts.

[0017] Embodiment one, please refer to the accompanying drawings Figure 1 The present application provides a high-safety grounding wire management system, wherein the high-safety grounding wire management system is used to implement the steps of a high-safety grounding wire structure, and the high-safety grounding wire management system comprises:

[0018] The data monitoring module 11 is configured to acquire real-time monitoring data based on the state monitoring assembly, wherein the real-time monitoring data comprises lead temperature information, grounding terminal contact resistance, grounding rod burial depth displacement, and resistance-reducing agent water content.

[0019] In particular, the high-safety grounding wire management system is provided with a lead, a grounding terminal, a grounding rod, a resistance-reducing agent, and a state monitoring assembly. The lead is a cable connecting the power equipment and the grounding terminal, used for transmitting current and ensuring that the current can smoothly flow to the ground through the grounding system. The grounding terminal is a part of the grounding wire, used for connecting the grounding cable and the grounding equipment, usually located at the interface of the grounding system, ensuring the stable inflow of current into the grounding system. The grounding rod is one of the main components in the grounding system, usually buried underground, used to reduce the grounding resistance, usually made of materials with strong conductivity (such as copper, steel), and realizes the import of current through contact with underground soil. The resistance-reducing agent is a chemical substance used to improve the grounding resistance, reducing the grounding resistance by increasing the conductivity of the soil, usually used around the grounding rod or grounding cable in the grounding system to improve the efficiency and stability of the grounding wire. The state monitoring assembly is a device used to monitor the working state of the grounding system, which can obtain real-time data of the system in operation, including various sensors such as temperature sensors, resistance sensors, displacement sensors, and humidity sensors, used to obtain real-time data of the grounding wire and its surrounding environment.

[0020] The various sensors in the state monitoring assembly (temperature sensor, resistance sensor, displacement sensor, humidity sensor) are responsible for collecting real-time parameter information related to the state of the grounding wire. Monitor the temperature of the lead. Assuming that in a test, the temperature of the lead of the grounding wire is 30℃. If the temperature exceeds a certain threshold (such as 60℃), it may indicate that the grounding wire is overloaded or the grounding system has a fault. Monitor the contact resistance between the grounding terminal and the grounding rod. Assuming that the contact resistance is 0.5Ω, indicating that the grounding system is working well. If the resistance exceeds the preset value (such as 1Ω), it indicates that the contact is poor and the grounding effect is poor. Monitor the displacement of the grounding rod. Assuming that the original burial depth of the grounding rod is 1.5 meters, but after a period of use, the displacement is detected to be 1.2 meters, indicating that the grounding rod may have been displaced due to soil loosening or other reasons, which may affect the grounding effect. Monitor the humidity of the soil around the resistance-reducing agent. In the test, the humidity sensor detects that the humidity of the soil around the resistance-reducing agent is 40%. If the humidity is too low, the effect of the resistance-reducing agent may be greatly reduced, resulting in an increase in the grounding resistance.

[0021] Real-time monitoring data is the specific numerical information collected by various sensors in the state monitoring assembly at any time, which can reflect the current state of the grounding wire. By integrating various sensors and directly obtaining temperature, contact resistance, displacement, and moisture content, which are four core data closely related to grounding safety, the actual operating conditions of the grounding wire are mastered.

[0022] The risk assessment module 12 is used to assess the risk index through the real-time monitoring data.

[0023] Further, as shown in the accompanying drawings Figure 2As shown, the risk assessment module 12 in the high-safety grounding wire management system is also used for: a model construction unit 21, for constructing a risk assessment model with lead temperature information, grounding terminal contact resistance, grounding rod burial depth displacement, and resistance reducing agent water content as input features; and an online learning unit 22, for the risk assessment model to update model parameters in a dynamic period through an online learning mechanism.

[0024] Further, the risk assessment module 12 in the high-safety grounding wire management system is also used for: a period updating subunit, for updating the dynamic period based on the operating environment of the grounding wire structure; and a model optimization subunit, for optimizing model parameters of the risk assessment model through an online learning mechanism based on the updated dynamic period.

[0025] Further, the risk assessment module 12 in the high-safety grounding wire management system is also used for: defining the real-time monitoring data stream accumulated in the last dynamic period as an incremental training set; and using the incremental training set to optimize model parameters of the risk assessment model.

[0026] Specifically, lead temperature, grounding terminal contact resistance, grounding rod burial depth displacement, and resistance reducing agent water content are taken as input features to construct a risk assessment model, to evaluate the current risk level of the grounding system, and to predict whether there is a potential failure or safety hazard in the grounding wire through these features. The risk assessment model is a mathematical model based on multiple input features (such as temperature, contact resistance, burial depth displacement, humidity, etc.) to evaluate the current safety or failure probability of the grounding system, and to evaluate the risk level of the system by comprehensive analysis of multiple factors. For example, assuming that in a certain monitoring period, the values of the input features are as follows: lead temperature 40℃, grounding terminal contact resistance 0.4Ω, grounding rod burial depth displacement 1.3 meters, and resistance reducing agent water content 45%, the risk assessment model calculates a risk index through a predetermined algorithm (such as a regression model, a neural network, a decision tree, etc.), indicating the current safety risk level of the grounding system.

[0027] The risk assessment model is updated and optimized through an online learning mechanism. The online learning mechanism allows the model to continuously receive new data and adjust its parameters to adapt to real-time changes in system status. Over time, the status of the grounding wire changes, and new sensor data such as lead temperature, resistance value, displacement, humidity is continuously collected and input into the model. The learning cycle is automatically adjusted according to the use environment of the grounding wire, such as seasonal changes, environmental temperature, load fluctuations, etc. For example, increase the monitoring frequency in winter, collect more data in real time, so as to quickly reflect the influence of environmental changes on the grounding system. Assuming that the dynamic cycle is set to be updated every hour, or adjusted to be updated every 15 minutes according to the system load state. Whenever new data is input, the model parameters are automatically updated according to the online learning mechanism. The online learning mechanism optimizes the weights and parameters in the risk assessment model by processing new data. For example, if the contact resistance of the grounding terminal suddenly increases, the weight of this feature is automatically increased to improve the sensitivity to contact resistance abnormalities and capture abnormal changes in time.

[0028] After online learning and dynamic cycle updates, the model can more accurately assess the risk of the grounding system. After new data is input, the risk assessment model recalculates the risk index and issues an alarm according to the evaluation results. For example, if the risk index exceeds the set safety threshold (such as a risk index greater than 0.8) after several updates, a warning is triggered to remind maintenance personnel to check or repair.

[0029] The operating environment of the grounding wire structure is the physical and environmental conditions in which the grounding system is located, such as soil humidity, temperature changes, seasonal changes, power system load, climate conditions, etc., which directly affect the working state and safety of the grounding wire. Changes in the operating environment of the grounding wire will affect the status of the grounding system. For example, in the rainy season, increased humidity may affect the effectiveness of the resistance-reducing agent, causing the grounding resistance to change; while in the dry season, reduced soil humidity may cause the grounding rod to lose effectiveness. These changes in environmental factors need to be optimized by adjusting the dynamic cycle to optimize the monitoring frequency. According to the operating environment, the dynamic cycle is updated, and the dynamic cycle is the time interval for updating model parameters, which will be automatically adjusted according to changes in the operating environment of the grounding system and other key factors. The dynamic cycle can update the parameters more frequently to respond to rapid changes in the grounding wire state, or reduce the update frequency according to environmental stability.

[0030] When environmental changes are detected and the dynamic period is adjusted according to these changes, the parameters of the risk assessment model are optimized in real time through an online learning mechanism, enabling the model to automatically adapt and optimize its assessment accuracy according to new environmental data. When the dynamic period is determined (e.g., adjusting from hourly updates to 15-minute updates), new sensor data (such as lead temperature, resistance, burial displacement, and humidity) is frequently input into the model, allowing the model to adjust its weights and parameters at the end of each period. After each new data input, the online learning mechanism optimizes the model's parameters based on the latest data. For example, suppose the original model's ground terminal contact resistance weight is 0.3, and under the influence of new data, the model adjusts the weight to 0.5 through online learning, reflecting an increase in the importance of ground terminal contact resistance to risk assessment. With the support of new data streams, the model becomes more sensitive to changes in input features, particularly in parameters such as ground resistance and temperature. Suppose the risk index calculated by the optimized parameters increases from 0.6 to 0.8, indicating an increase in the risk of the grounding wire. This risk index will trigger an alarm system, prompting relevant personnel to conduct an inspection.

[0031] Through continuous dynamic period adjustment and online learning optimization, the evaluation capability of the grounding system state is continuously improved. In seasons with high temperatures or heavy loads, frequent parameter updates ensure that the risk assessment model can reflect the potential risks of the grounding system in real time, avoiding electrical accidents. In stable seasons, by adjusting the dynamic period to reduce the update frequency, the use of computing resources is optimized. The online learning mechanism enables the model to automatically adapt to different environmental changes, reducing the need for manual model adjustments and improving management efficiency. The cumulative real-time monitoring data stream in the previous dynamic period serves as the incremental training set, which means that all real-time data collected from sensors in the grounding wire management system (such as temperature sensors, resistance sensors, humidity sensors, etc.) within a dynamic period (e.g., every hour, every 15 minutes, etc.) contains detailed information about the grounding system state, such as lead temperature, ground terminal contact resistance, ground rod burial displacement, and resistance reduction agent humidity.

[0032] The incremental training set refers to the newly added data within each dynamic period, which serves as input data for optimizing the risk assessment model. Through incremental learning, the risk assessment model can continuously optimize based on new data streams without the need to retrain the entire risk assessment model, improving training efficiency and enabling the risk assessment model to quickly adapt to new data changes. By using all monitoring data streams collected within the above dynamic period as an incremental training set, it serves as new input to optimize the parameters of the risk assessment model. The role of the incremental training set is to gradually update the model's parameters with the latest data stream, enabling the model to better adapt to new grounding wire state changes. The incremental training set will include combinations of all data points, such as changes in lead temperature, ground terminal contact resistance, burial displacement, and resistance reduction agent moisture content.

[0033] After using the incremental training set, the risk assessment model will adjust and optimize its internal parameters based on this newly added real-time data. The risk assessment model will adjust weights according to the input features (such as temperature, resistance, displacement, and humidity) in the incremental training set, enabling it to accurately predict the risks of the grounding system. The optimization process typically uses online learning algorithms, such as stochastic gradient descent (SGD) and Bayesian optimization, to gradually reduce the error between the model's predictions and the actual data. In this way, the risk assessment model continuously adapts to new data and environmental changes. Assume that during the optimization process based on the incremental training set, the model updates the following parameters: lead temperature weight: original weight 0.2, updated to 0.3; grounding terminal contact resistance weight: original weight 0.3, updated to 0.35; grounding rod burial depth displacement weight: original weight 0.25, updated to 0.2; resistance-reducing agent moisture content weight: original weight 0.25, updated to 0.15. Increased attention is paid to lead temperature and grounding terminal contact resistance, while decreased attention is paid to resistance-reducing agent humidity. After optimization, the model's predictive ability is enhanced, enabling it to more accurately reflect the risk status of the grounding system.

[0034] Real-time monitoring data is input into a risk assessment model for risk evaluation, outputting a risk index. The risk index, typically a value between 0 and 1, represents the current risk level of the grounding wire management system. A higher risk index indicates a higher risk of faults or safety hazards in the grounding system, while a lower risk index indicates stable system operation and less risk. By calculating the risk index, the status of the grounding wires can be assessed in real time, allowing for the timely detection of potential risks.

[0035] The risk assessment module 13 is used to assess the risk based on the risk index and provide risk warnings based on the assessment results.

[0036] Furthermore, the risk determination module 13 in the high-safety grounding wire management system is also used for: an electronic fence integration unit for integrating electronic fence functions; and a range division unit for defining the range of the electronic fence when the grounding rod burial depth displacement exceeds the safe displacement threshold or the grounding terminal contact resistance exceeds the contact resistance tolerance range.

[0037] Furthermore, the risk determination module 13 in the high-security grounding wire management system is also used for: a coordinate acquisition subunit, used to obtain the coordinates of the grounding rod based on the GIS unit; and a radius determination subunit, used to determine the fence radius corresponding to the electronic fence range based on the coordinates of the grounding rod and the grounding rod burial depth displacement.

[0038] Further, the risk determination module 13 in the high-safety grounding line management system is also configured to: configure a basic safety radius through the grounding line voltage level; determine a fence expansion radius according to the absolute value of the grounding rod depth displacement; and sum the basic safety radius and the fence expansion radius to obtain a fence radius corresponding to the electronic fence range.

[0039] Specifically, the electronic fence function is integrated in the grounding line management system to monitor and manage through the setting of a virtual safety area. When some parameters of the grounding line system (such as the grounding rod depth displacement and the grounding terminal contact resistance) are abnormal, a range is defined by the electronic fence to issue an alarm to the management personnel, thereby playing a protective role. The safety displacement threshold of the grounding rod and the contact resistance tolerance interval of the grounding terminal are set. The safety displacement threshold refers to the maximum allowable value of the grounding rod depth displacement. When the displacement of the grounding rod exceeds the threshold, it indicates that the grounding rod has experienced abnormal displacement, which may lead to poor grounding effect, thereby triggering an alarm. The contact resistance tolerance interval refers to the normal range of the contact resistance of the grounding terminal. If the contact resistance of the grounding terminal exceeds the tolerance range, it may indicate that the grounding terminal does not contact the grounding rod well, affecting the grounding effect.

[0040] The grounding rod depth displacement refers to the change in the depth of the grounding rod in the ground. Under normal circumstances, the grounding rod should be kept at a fixed depth to ensure its normal operation. If the depth of the grounding rod changes due to soil loosening, settlement or other external forces, it will affect the grounding effect. The grounding terminal contact resistance refers to the resistance between the grounding terminal and the grounding rod. High contact resistance will lead to poor grounding effect, causing equipment failure or electrical safety problems.

[0041] In real-time monitoring data, when the depth displacement of the grounding rod exceeds the safety displacement threshold, or the contact resistance of the grounding terminal exceeds the contact resistance tolerance interval, a virtual risk area is defined by the electronic fence function, and an alarm is triggered. For example, if the depth displacement of the grounding rod is 1.7 meters, which exceeds the set safety displacement threshold of 1.5 meters, and the contact resistance of the grounding terminal is 0.6Ω, which also exceeds the set tolerance interval of 0.5Ω, a safety area is defined by the electronic fence function, and an alarm is issued. The electronic fence range refers to a virtual area defined when the system detects an anomaly. A specific risk threshold is set, and when the parameters of the grounding system (such as the depth displacement or the contact resistance) exceed the range, the system will trigger an alarm.

[0042] The GIS unit refers to the module in the system for acquiring and processing geographic location information. In the grounding wire management system, the GIS unit can provide the geographic location coordinates of the grounding rod to enable precise geospatial analysis and monitoring. Through the GIS unit, the geographic coordinates of the grounding rod are obtained, which refers to the position of the grounding rod in the geographic space, using latitude and longitude or a plane coordinate system (such as UTM coordinates) to represent the specific position of the grounding rod.

[0043] According to the grounding rod coordinates, combined with the grounding rod depth displacement, the fence radius corresponding to the electronic fence range is determined. The position displacement of the grounding rod will affect its grounding performance, and the radius of the electronic fence is dynamically adjusted according to the change of the depth displacement, so as to provide accurate protection area according to the risk situation. The basic safety radius is a fixed radius, usually related to the voltage level of the grounding wire and safety standards, assuming that the basic safety radius is 1 meter. With the depth displacement of the grounding rod, the radius of the fence needs to be increased to ensure that the safety area can cover the possible risk influence range of the grounding rod. Usually, for every certain amount of depth displacement, the fence radius will also be expanded accordingly. Assuming that for every 0.1 meter of depth displacement, the fence radius increases by 0.2 meters.

[0044] According to the coordinates of the grounding rod and the calculated fence radius, an electronic fence range is drawn on the GIS map. Ensure that within this range, if the grounding rod has a depth displacement anomaly or other faults, an alarm can be sent in time. When the depth displacement of the grounding rod exceeds the threshold (such as displacement exceeding 0.3 meters), or the grounding terminal contact resistance exceeds the tolerance interval, the electronic fence function is activated.

[0045] The grounding wire voltage level refers to the maximum voltage that the grounding wire in the power system can withstand, which determines the safety standards and design requirements of the grounding wire system. The higher the voltage level, the more stringent the safety requirements for the grounding wire. Through the grounding wire voltage level, the basic safety radius is configured. The size of the grounding wire voltage level directly affects the safety standards of the grounding system. The basic safety radius is a fixed protection radius set according to the grounding wire voltage level, used to protect the safety of the area around the grounding system, usually related to the voltage level, the higher the voltage, the basic safety radius is usually larger.

[0046] The absolute value of the grounding rod depth displacement represents the change in the depth of the grounding rod, and the normal depth of the grounding rod is predetermined during design, any change in the depth may affect the grounding effect. According to the depth displacement of the grounding rod, the radius of the fence is dynamically adjusted. For example, for every 0.1 meter of depth displacement, the fence expansion radius increases by 0.2 meters. If the initial depth of the grounding rod is 1.5 meters, after a certain period of monitoring, the depth of the grounding rod has changed by 0.3 meters, i.e. the actual depth of the grounding rod becomes 1.8 meters.

[0047] The absolute value of the displacement of the grounding rod burial depth refers to the change amount of the grounding rod burial depth compared to its initial burial depth, ignoring the direction. The displacement of the grounding rod burial depth is usually caused by soil settlement, external force influence, etc., which will affect the effectiveness and safety of the grounding system. The foundation safety radius is a fixed protection radius set according to the voltage grade of the grounding line, used to protect the safety of the surrounding area of the grounding system, and is usually related to the voltage grade. The higher the voltage, the larger the foundation safety radius is usually. The fence expansion radius is a radius range that is dynamically adjusted according to the displacement change of the grounding rod burial depth. When the grounding rod displacement occurs, the expansion radius will increase to ensure that the abnormal change of the grounding rod is covered by enough safety area.

[0048] The foundation safety radius and the fence expansion radius are added to obtain the final electronic fence radius, thereby determining the safety range around the grounding rod. Assuming that the foundation safety radius is 1 meter (applicable to low-voltage grounding lines), and the fence expansion radius is 0.6 meters (determined by the displacement of the grounding rod burial depth), then the final electronic fence radius is 1.6 meters. According to the electronic fence radius, a circular electronic fence area is drawn in the GIS (Geographic Information System). The center of this circular area is the position of the grounding rod, and the radius is the electronic fence radius calculated by the foundation safety radius and the fence expansion radius.

[0049] The risk index is a numerical value calculated by the risk assessment model, representing the current risk level of the grounding system. The numerical range of the risk index is usually between 0 and 1, and the higher the value, the greater the risk, and the lower the value, the more stable the system runs. According to the calculated risk index, risk judgment is carried out. Risk judgment compares the risk index with the preset risk level threshold to determine the current risk level of the grounding system. Assuming that the risk level threshold is set as follows: the risk index of low risk is less than 0.3, the risk index of medium risk is between 0.3 and 0.7, and the risk index of high risk is greater than 0.7. In this assumption, the risk index of 0.75 exceeds 0.7, so it will be judged as a high risk state. According to the result of risk judgment, risk prompt is generated, and specific measures to be taken are provided for managers. When the grounding system is in a high risk state, the warning mechanism sends a notification to the relevant staff. The content of the notification may include the type of alarm, detailed risk information, and emergency response steps. By calculating the risk index in real time, potential risk problems of the grounding system are identified in a timely manner, thereby improving management efficiency. According to the judgment result, specific risk prompt and emergency response suggestion are provided to help staff take correct measures in the first time and reduce the possibility of accidents.
