[0014] Advantages of the present invention: The power transmission line safety warning system based on artificial intelligence and Beidou positioning proposed by the present invention is generally composed of a power transmission line data acquisition module, a power transmission line damage assessment module, a tower safety fault identification module, and a safety fault positioning and warning module. Compared with the prior art, the beneficial effects of this application are as follows: By deploying image sensors, current sensors, and voltage sensors on the power transmission line, multi-source data acquisition of the power transmission line towers is realized. The image sensor can capture image information of the power transmission line and the surrounding environment of the tower, including influencing factors such as trees, bird nests, and weather changes, which helps to comprehensively understand the status of the surrounding environment. The current sensor and voltage sensor respectively record the current and voltage components of the power transmission line. Through all-round and multi-dimensional data acquisition, the environment and operating status of the power transmission line towers are comprehensively monitored, effectively improving the perception ability of equipment and environment. The cooperation of multiple sensors not only makes data collection more accurate but also can timely capture any abnormal situations that cause failures or dangers. For example, by identifying trees and bird nests in the environment through the image sensor, problems such as too-close trees and bird nest construction can be timely warned, effectively reducing the risk of line failures caused by natural factors. The real-time monitoring of current and voltage data can quickly locate problems when abnormalities occur, ensuring the efficient operation of the power transmission line. Secondly, by obtaining the distance between trees and bird nests based on the images of the power transmission line tower environment and combining these data to conduct a safety damage assessment of the line. The distance between trees and power facilities, the number and location of bird nest construction directly affect the operation safety of the power transmission line. If the trees are too close to the power transmission line, it may cause branches to contact the line, resulting in short circuits or fires; the construction of bird nests hinders the normal operation of the power transmission line and may even cause electrical failures, thus avoiding accidents and failures caused by environmental problems. Further, this assessment mechanism can be widely applied in large-scale power transmission line networks, thereby enhancing the image and data processing capabilities in complex environments. Then, by obtaining the environmental external cause faults corresponding to the power transmission line through the safety damage rate of the power transmission line, it helps to identify environmental external cause electrical faults caused by environmental problems (such as tree proximity, bird nest influence, etc.), and combines a convolutional neural network to conduct safety fault identification on current and voltage data, which can deeply analyze the operating status of the power transmission line. As a deep learning method, the convolutional neural network (CNN) can extract internal potential patterns and features from a large amount of current and voltage data, identify the differences between normal and abnormal states. Compared with traditional manual monitoring, the artificial intelligence analysis of the convolutional neural network greatly improves the accuracy and efficiency of fault identification, can quickly locate possible fault points, and predict future faults through algorithms. Through this intelligent safety analysis, the failure rate and accident probability of the power transmission line are greatly reduced, effectively improving the stability and safety of the power transmission line.Finally, by integrating the Beidou positioning module, the positioning and early warning of safety faults of transmission line towers are realized, providing accurate geographical information for fault repair. The Beidou positioning module can obtain the position of transmission line towers in real time and combine it with the fault identification result to quickly determine the specific tower position where the problem occurs, thus meeting the demand for precise positioning of transmission line faults. This process can accurately locate the fault position information to specific coordinates, providing intuitive guidance for on-site repair personnel, saving a lot of time. In this way, the integration of the Beidou positioning module makes the fault positioning more accurate, enabling the repair personnel to be accurately guided to the fault occurrence point, avoiding wasting time due to errors or unfamiliar terrain, and thus greatly improving the accuracy of safety early warning and the emergency response ability.

In this example, the transmission line safety warning system based on artificial intelligence and Beidou positioning includes the following modules: S1: Transmission line data acquisition module, which is used to deploy image sensors, current sensors, and voltage sensors on the transmission line, and use the image sensors, current sensors, and voltage sensors to collect multi-source line data for the corresponding transmission line towers around the transmission line, so as to obtain the transmission line tower environment image, the transmission line tower current component, and the transmission line tower voltage component; and transmit the transmission line tower environment image, the transmission line tower current component, and the transmission line tower voltage component to the data processing center in real time; In the embodiment of the present invention, by deploying image sensors, current sensors, and voltage sensors on each tower of the transmission line, the image sensor is used to capture the environment image around the tower, including information such as vegetation and bird nests. The current sensor is used to collect the current component of the transmission line on the tower, and the voltage sensor is used to collect the voltage component of the transmission line on the tower. Each sensor is equipped with high-precision measurement and acquisition equipment to ensure the accuracy of the data. The image sensor captures images in real time through a high-definition camera, and the current and voltage sensors convert the signals into digital data through a data acquisition card. The data collected by each sensor is transmitted to the data processing center in real time by wired or wireless means. During this process, the communication module ensures that the data will not be lost during transmission and maintains the real-time nature and integrity of the data. The data processing center receives and stores all the uploaded data for further analysis and processing.
[0021] S2: Transmission line damage assessment module, which is used to obtain the relative distance of the corresponding trees and the number of bird nests built through the transmission line tower environment image, and perform a safety damage assessment calculation on the transmission line corresponding to the tower based on the relative distance of the trees and the number of bird nests built, so as to obtain the transmission line safety damage rate; In the embodiment of the present invention, the environment image of the transmission line tower is processed by image recognition technology. Using image processing algorithms, the trees in the image and their relative positions to the tower are identified, and the relative distance of the trees is calculated. At the same time, deep learning algorithms are used to identify the number of bird nests built in the image, especially the number of bird nests near the structural part of the tower. Through the analysis of the relative distance of the trees and the number of bird nests built, combined with the previously known safety damage model, the safety damage rate of the transmission line tower is calculated. This model evaluates the possible damage risk based on the tree proximity, the number of bird nests, and other environmental factors (such as the probability of leakage). This damage rate represents the probability of damage to the transmission line caused by external environmental influences, and finally the transmission line safety damage rate is obtained.
[0022] S3: Tower safety fault identification module, which is used to perform safety fault identification and analysis on the transmission line tower current component and the transmission line tower voltage component based on the transmission line safety damage rate and combined with a convolutional neural network, so as to obtain the transmission line tower safety fault identification result; In an embodiment of the present invention, after obtaining the safety breakage rate of a transmission line tower, the safety breakage rate of the transmission line is used to obtain the environmental external factor faults corresponding to the transmission line, so as to help identify environmental external factor electrical faults caused by environmental problems (such as tree proximity, bird's nest influence, etc.), and combined with a convolutional neural network to perform safety fault identification on current and voltage data. First, using the trained convolutional neural network model, the current component and voltage component data of the transmission line tower are input for real-time analysis. Through the neural network's feature extraction of the current and voltage signals, the identified electrical fault modes, such as overload, short circuit, etc., the convolutional neural network can accurately identify potential faults in the power system through training of historical data, and by combining with the safety breakage rate, judge the severity and location of the faults, and finally obtain the safety fault identification result of the transmission line tower, including environmental external factor faults and line internal factor faults.

[0024] In an embodiment of the present invention, by integrating a Beidou positioning module on each tower, this positioning module can obtain the position of the tower in real time and associate it with the fault identification result. When a safety fault occurs in a certain transmission line tower, the Beidou positioning system will accurately mark the geographical location of the tower. This position data and the fault diagnosis result are jointly transmitted to the data processing center, and real-time fault warning is carried out through the background system. The data processing center analyzes the location, type and severity of the fault according to the warning information, and promptly sends the fault warning information to the relevant maintenance department or repair team. After receiving the warning, the repair team quickly finds the fault location through the positioning information, starts the repair procedure, ensures timely handling of the fault problem of the transmission line, reduces the outage time, and guarantees the stability of power supply. Finally, the fault warning location of the transmission line tower is located and the corresponding transmission line fault warning and repair work is executed.

In areas with strong signals, fiber optic transmission technology is used to transmit a large amount of environmental images, current data, and voltage data with high bandwidth. In remote or weak-signal areas, relay stations are built or wireless communication technology is used to transmit the collected data to the main data processing center through the relay stations. These data will be transmitted to the data center through the network for further real-time processing and analysis. The data center uses artificial intelligence algorithms to perform risk assessment based on this real-time information and feedback warning information to the management system.

Then, a convolutional neural network (CNN) model is applied, combined with a pre-trained bird's nest recognition data set, to accurately identify the positions of the bird's nests in the images. During the recognition process, special attention is paid to the spatial relationships between the bird's nests and the towers and transmission lines to ensure that the bird's nests built around the transmission lines and towers are accurately counted, the number of bird's nests around each tower in the image is counted, and detailed bird's nest position and quantity information is output, and finally the corresponding number of bird's nests built is obtained.
[0035] S23: Obtain the environmental humidity and environmental precipitation corresponding to the periodic area through the corresponding towers around the transmission line, and calculate the leakage probability of the transmission line corresponding to the tower based on the environmental humidity and environmental precipitation to obtain the leakage probability of the transmission line tower. In the embodiment of the present invention, by obtaining the meteorological data corresponding to the positions around each tower, the values of environmental humidity and precipitation can be obtained through the surrounding weather stations or through a mobile sensor network. These data can reflect the humidity and precipitation of the surrounding environment in real time. The obtained environmental humidity and precipitation are input into the leakage risk assessment model, and based on the existing empirical data and algorithms, the leakage probability of each tower area is calculated. The calculation of the leakage probability involves multiple parameters such as environmental factors and line load, and the insulation state of the line is evaluated by using these parameters, and finally the leakage probability of the transmission line tower is obtained.
[0036] S24: Based on the distance between trees, the number of bird nests built, and the leakage probability of transmission line towers, a safety damage assessment calculation is performed on the transmission line corresponding to the tower to obtain the safety damage rate of the transmission line.
[0037] In an embodiment of the present invention, a comprehensive safety assessment formula is constructed by combining previously acquired data on the distance between trees and the number of bird nests, and the obtained leakage probability. The formula comprehensively considers the possibility of physical contact between trees and transmission lines, the impact of bird nests on the insulation performance of lines, and the risk of leakage probability. If trees are close to transmission lines, especially under extreme weather conditions such as wind or precipitation, the risk of trees falling over increases, causing line damage; when there are a large number of bird nests, the activities of birds may affect the mechanical or electrical safety of the lines; and the increase in the probability of leakage, especially in conditions of high humidity and precipitation, increases the risk of power system failure. By incorporating these factors into a comprehensive weighted algorithm model, the safety damage rate of the line corresponding to each tower is calculated, and finally the safety damage rate of the transmission line is obtained.
[0038] Furthermore, the step of obtaining the ambient humidity and ambient precipitation corresponding to the periodic area through the corresponding towers around the transmission line, and calculating the leakage probability of the transmission line corresponding to the towers based on the ambient humidity and ambient precipitation includes: Obtain the corresponding ambient humidity and ambient precipitation in the surrounding area through the corresponding towers around the transmission lines and in combination with the meteorological monitoring station; In an embodiment of the present invention, the ambient humidity and ambient precipitation corresponding to the surrounding area are obtained through the corresponding pole towers around the transmission line in combination with the data from the meteorological monitoring station. First, meteorological monitoring equipment needs to be installed at various key locations around the transmission line. The equipment can collect ambient humidity and precipitation data in real time. The locations of these meteorological monitoring equipment should be reasonably arranged to cover all important areas along the transmission line to ensure that the collected environmental data are representative. By connecting to the data transmission system of the meteorological monitoring station, the monitored ambient humidity and precipitation data are transmitted to the central control system in real time. Through the data transmission network, the ambient humidity and precipitation data of each meteorological monitoring station within a specified time period can be obtained, and finally the ambient humidity and ambient precipitation corresponding to the surrounding area are obtained.
[0039] Preferably, the ambient humidity and ambient precipitation corresponding to the surrounding area are calculated by arithmetic average at fixed time intervals of 30 minutes to obtain the average ambient humidity and average ambient precipitation; In the embodiment of the present invention, by performing arithmetic mean calculation on the ambient humidity and ambient precipitation corresponding to the surrounding area at a fixed time interval of 30 minutes, after obtaining the humidity and precipitation data collected by the meteorological monitoring station, the data is grouped according to the time interval to ensure that each group of data represents the environmental state of 30 minutes. On this basis, the arithmetic mean method is used to calculate the average value of each group of data, and the average ambient humidity and average ambient precipitation during this period are obtained. Specifically, assuming that there are n humidity values and precipitation values in a certain time period, the average ambient humidity and average ambient precipitation can be respectively expressed as the sum of these n values divided by n, that is, the average values of humidity and precipitation in each 30-minute time period are calculated respectively, and finally the average ambient humidity and average ambient precipitation are obtained.
[0040] Preferably, a tilt monitor is used to collect the pole tilt of the poles corresponding to the transmission line to obtain the pole tilt angle of the transmission line tower. In the embodiment of the present invention, by using a tilt monitor to collect the tilt of the poles corresponding to the transmission line to obtain the pole tilt angle, at each key position of the transmission line, a fixed pole tilt monitor is set up, which can collect and record the tilt data of the pole in real time. The tilt monitor can use high-precision sensors, such as tilt sensors or acceleration sensors, to accurately measure the offset of the pole in the vertical direction. By connecting to the data acquisition system, the monitor can automatically record and upload data at regular intervals (such as every minute). At the system end, after receiving the tilt data of the pole, the data is analyzed through a preset algorithm to obtain the tilt angle of each pole at a specific moment, and finally the pole tilt angle of the transmission line tower is obtained.
[0041] Preferably, based on the pole tilt angle of the transmission line tower, the average ambient humidity, and the average ambient precipitation, the leakage probability calculation formula for the pole line is used to calculate the leakage probability of the transmission line corresponding to the pole to obtain the leakage probability of the transmission line tower.
[0042] In the embodiment of the present invention, by combining the maximum pole tilt angle, the minimum ambient humidity, the maximum ambient humidity, the minimum precipitation, the maximum precipitation, the pole tilt angle parameter, the pole tilt contribution coefficient, the ambient humidity parameter, the average ambient humidity, the ambient humidity standard deviation, the ambient precipitation parameter, the average ambient precipitation, the ambient precipitation standard deviation, the environmental parameter contribution coefficient, and related parameters, a suitable leakage probability calculation formula for the pole line is constructed for quantitative calculation of the probability to calculate the probability of the pole leakage under the given environmental conditions, and finally the leakage probability of the transmission line tower is obtained. In addition, this leakage probability calculation formula for the pole line can also use any leakage detection algorithm in the field to replace the process of leakage probability calculation, and is not limited to this leakage probability calculation formula for the pole line.
[0043] Furthermore, the specific formula for calculating the leakage probability of the pole and tower line is as follows: ; In the formula, is the leakage probability of the transmission line pole and tower, is the maximum inclination angle of the pole and tower, is the minimum value of the environmental humidity, is the maximum value of the environmental humidity, is the minimum value of the precipitation, is the maximum value of the precipitation, is the pole and tower inclination angle parameter, is the pole and tower inclination contribution coefficient, is the environmental humidity parameter, is the average environmental humidity, is the standard deviation of the environmental humidity, is the environmental precipitation parameter, is the average environmental precipitation, is the standard deviation of the environmental precipitation, is the environmental parameter contribution coefficient, is the correction coefficient of the leakage probability of the transmission line pole and tower.
[0044] The present invention has obtained a leakage probability calculation formula for tower lines through the use of a specific mathematical model and verification, which is used to calculate the leakage probability of the transmission line corresponding to the tower. This leakage probability calculation formula for tower lines comprehensively evaluates the leakage probability of the transmission line tower by combining multiple factors (such as tower inclination angle, environmental humidity, precipitation, etc.). Different environmental conditions (such as humidity, precipitation, tower inclination) will all affect the leakage risk. The formula can accurately take these factors into consideration, thereby providing an effective prediction for the safe operation of the transmission line. Tower inclination is an important factor affecting the safety of the transmission line. By adding a parameter of the inclination angle to the formula, the influence of the inclination on the leakage probability can be quantified. Especially in cases of adverse weather or geological activities (such as earthquakes, floods, etc.), the inclination angle of the tower may change, leading to an increase in the leakage risk. The introduction of this formula can predict in advance and take protective measures in these cases to avoid leakage problems caused by changes in the tower structure. By comprehensively analyzing the standard deviation and mean value of environmental humidity and precipitation, the formula can reflect the complex non-linear influence of humidity and precipitation on leakage. Excessively high humidity or precipitation will significantly increase the leakage risk, while lower humidity and precipitation will reduce this risk. By dynamically calculating the contribution of humidity and precipitation to leakage, it can provide a safety assessment for power companies based on real-time weather changes. In addition, the correction coefficient in the formula can be adjusted according to actual situations, so as to flexibly cope with the leakage risk under different environmental and operating conditions. This coefficient enables the formula to have the ability to adapt to different regions and different climate conditions, helping to more accurately evaluate the leakage probability and make targeted adjustments to measures. The and are respectively used to measure the influence degrees of tower inclination and environmental factors (humidity, precipitation). Through the adjustment of the weight coefficient, the roles of different factors in the leakage probability can be highlighted, thereby optimizing the maintenance and monitoring strategies of the transmission line in a targeted manner. To sum up, this formula fully considers the leakage probability of the transmission line tower , the maximum tower inclination angle , the minimum environmental humidity , the maximum environmental humidity , the minimum precipitation , the maximum precipitation , the tower inclination angle parameter , the tower inclination contribution coefficient , the environmental humidity parameter , the average environmental humidity , the environmental humidity standard deviation , the environmental precipitation parameter , the average environmental precipitation , the environmental precipitation standard deviation , the environmental parameter contribution coefficient , correction factor of the leakage probability of transmission line towers , according to the leakage probability of transmission line towers and the mutual correlation relationship with the above parameters constitutes a functional relationship , this formula can realize the calculation process of the leakage probability of the transmission line corresponding to the tower. At the same time, through the correction factor of the leakage probability of the transmission line tower The introduction of can be adjusted according to the error situation in the calculation process, thereby improving the accuracy and applicability of the leakage probability calculation formula of the tower line.
[0045] Further, the safety damage assessment calculation of the transmission line corresponding to the tower based on the distance of trees, the number of bird nests built, and the leakage probability of the transmission line tower includes: Obtain the growth trend of the tree branches corresponding to the distance of the trees, and conduct a mechanical damage assessment on the transmission line corresponding to the tower based on the growth trend of the tree branches to obtain the mechanical damage coefficient of the transmission line; In the embodiment of the present invention, by using high-precision lidar (LIDAR) technology or high-resolution satellite remote sensing images, the trees along the transmission line are measured to obtain the distance between the trees and the transmission line, the height of the trees, the distribution of branches and other relevant data. Then, apply artificial intelligence algorithms (such as convolutional neural networks in deep learning) to analyze the growth trend of the trees, predict the growth of the trees in a certain period of time in the future. The growth trend of the trees usually considers climatic conditions, tree species characteristics and the growth rate of the trees. By establishing a mathematical model and combining real-time data for simulation and calculation, the mechanical damage caused by the trees to the transmission line in a certain period of time in the future is obtained, and finally the mechanical damage coefficient of the transmission line is obtained.
[0046] Preferably, measure the insulation resistance of the transmission line corresponding to the tower to obtain the insulation resistance of the transmission line; In the embodiment of the present invention, it is measured by using a special insulation resistance test instrument. During the implementation process, by accurately determining the position of the transmission line tower, ensure that the measuring device can be correctly placed at a specific test point, connect the insulation resistance tester to the wiring terminal of the transmission line, and measure the insulation resistance value of each line. When measuring, it is necessary to ensure that the working voltage and current of the measuring instrument meet the working standards of the transmission line to avoid equipment damage or inaccurate measurement caused by excessive test current. This test is repeated at different time intervals and environmental conditions to obtain multiple readings to evaluate the insulation status of the transmission line, and finally the insulation resistance of the transmission line is obtained.
[0047] Preferably, based on the number of bird nests built, conduct an insulation impact assessment analysis on the insulation resistance of the transmission line to obtain the insulation impact efficiency of the transmission line; In the embodiments of the present invention, according to the environment where birds inhabit around the transmission line, the number and distribution of bird nests are obtained through high-resolution images or manual monitoring. The number of bird nests built is statistically analyzed using machine learning algorithms. Combining the bird inhabitation habits, the impact of the bird nests on the insulation resistance of the transmission line is evaluated. The activities of birds and the presence of bird nests cause the transmission line to be contaminated, thereby affecting its insulation performance. Based on the statistical data of the number and location of bird nests built and combined with the insulation resistance test results, a comprehensive impact assessment model is established to calculate the specific impact efficiency of bird inhabitation on the insulation performance of the transmission line. This efficiency reflects the negative impact degree of the bird nest building on the insulation resistance, and finally the insulation impact efficiency of the transmission line is obtained.
[0048] Preferably, based on the mechanical damage coefficient of the transmission line, the insulation impact efficiency of the transmission line, and the leakage probability of the transmission line tower, the safety breakage rate calculation formula of the line is used to perform a safety breakage assessment calculation on the transmission line corresponding to the tower, and the safety breakage rate of the transmission line is obtained.
[0049] In the embodiments of the present invention, by combining the safety breakage assessment time interval, time variable parameter, mechanical damage coefficient of the transmission line, distance between the tree and the transmission line, distance mechanical damage weight, tree growth speed, tree growth mechanical damage weight, tree growth height, tree height mechanical damage weight, insulation impact efficiency of the transmission line, number of bird nests built, insulation resistance of the transmission line, insulation impact correction factor, leakage probability of the transmission line tower, leakage probability adjustment factor, and related parameters, a suitable safety breakage rate calculation formula of the line is formed for quantitative calculation to quantitatively obtain the safety breakage rate of the transmission line. This breakage rate represents the probability of the line having a fault or damage within a certain period of time and is an important indicator for evaluating the safety status of the line. Finally, the safety breakage rate of the transmission line is obtained. In addition, this safety breakage rate calculation formula of the line can also use any line breakage monitoring technology in the field to replace the process of safety breakage assessment calculation, and is not limited to this safety breakage rate calculation formula of the line.
[0050] Furthermore, the safety breakage rate calculation formula of the line is specifically: ; ; ; In the formula, is the safety breakage rate of the transmission line, is the safety breakage assessment time interval, is the time variable parameter, is the mechanical damage coefficient of the transmission line at time , is at time The distance between the trees and the transmission line is the weight of mechanical damage at time is the tree growth rate is the weight of mechanical damage caused by tree growth at time is the tree growth height is the weight of mechanical damage caused by tree height at time is the insulation influence efficiency of the transmission line at time is the number of bird nests built is the insulation resistance of the transmission line is the insulation influence correction factor is the leakage probability of the transmission line tower is the leakage probability adjustment factor is the correction coefficient of the safety breakage rate of the transmission line
[0051] The present invention has obtained a calculation formula for the line safety breakage rate through the use of a specific mathematical model and verification, which is used to calculate the safety breakage assessment of the transmission line corresponding to the pole tower. This calculation formula for the line safety breakage rate comprehensively considers the impacts of multiple factors (such as mechanical damage, insulation influence, and leakage probability, etc.) on the safety of the transmission line, and can comprehensively evaluate the safety breakage rate of the line. By introducing different parameters and correction factors, it can effectively reflect the comprehensive effects of various external and internal factors on the line safety, avoiding the limitations of a single factor. Through parameters such as the distance between the tree and the transmission line, the tree growth rate, and the height, combined with the mechanical damage weight, the formula can dynamically evaluate the impact of the tree growth process on the mechanical damage of the transmission line. This consideration of dynamic changes helps to predict future safety risks and take measures in advance to reduce potential line failures. By evaluating the number of bird nests built and combining with the insulation resistance of the transmission line, the formula can estimate the downward trend of the insulation performance. The building of bird nests may affect the integrity of the insulation, leading to leakage or short - circuit risks. Through this evaluation, it can provide a scientific basis for the insulation maintenance of the line. By considering the leakage probability, the formula can accurately evaluate the electrical safety of the line under different conditions. By introducing a leakage probability adjustment factor and a safety breakage correction coefficient, the formula can be flexibly adjusted according to the actual situation, making the prediction of the breakage rate more accurate and reliable. Multiple correction coefficients and dynamic time variables (such as time, tree growth status, etc.) in the formula can be adjusted at any time according to environmental changes and actual conditions, making the evaluation results more precise. Different environmental and operating conditions (such as tree growth, bird nest building, etc.) can affect the calculation of the line safety breakage rate in real - time, providing flexibility and accuracy. Since the formula can consider multiple dynamic factors, it can help engineers and maintenance personnel predict potential line damage in advance and take preventive measures in a timely manner. This not only improves the safety of the transmission line but also reduces power outages caused by line breakage, ensuring the stable operation of the power system. In summary, this formula fully considers the line safety breakage rate , the safety breakage assessment time interval , the time - variable parameter , at time , the mechanical damage coefficient of the transmission line , at time , the distance between the tree and the transmission line , the distance mechanical damage weight , at time , the tree growth rate , the tree growth mechanical damage weight , at time , the tree growth height , the tree height mechanical damage weight , at time The insulation of the transmission line at [location] affects the efficiency At time The number of bird nests built at [location] The insulation resistance of the transmission line The insulation influence correction factor The leakage probability of the transmission line tower The leakage probability adjustment factor The correction coefficient of the safety breakage rate of the transmission line Among them, by combining the time variable parameter At time The distance between the tree and the transmission line at [location] The distance mechanical damage weight At time The tree growth rate at [location] The tree growth mechanical damage weight At time The tree growth height at [location] And the tree height mechanical damage weight Constitute a transmission line mechanical damage coefficient at time at [location] Functional relationship Also, by combining the time variable parameter And at time The number of bird nests built at [location] Constitute a transmission line insulation influence efficiency at time at [location] Functional relationship According to the safety breakage rate of the transmission line The mutual correlation relationship with the above parameters constitutes a functional relationship This formula can realize the safety breakage assessment calculation process of the transmission line corresponding to the tower. At the same time, through the introduction of the correction coefficient of the safety breakage rate of the transmission line, it can be adjusted according to the error situation in the calculation process, thereby improving the accuracy and applicability of the formula for calculating the safety breakage rate of the line.
[0052] Furthermore, the tower safety fault identification module includes the following functions: By fitting the time series change curve of the safety breakage rate of the transmission line within a certain time range to generate the change trend curve of the transmission line breakage rate; In an embodiment of the present invention, by obtaining historical breakage rate data of a transmission line within a certain time range, the breakage rate data includes the occurrence frequency or damage degree of breakage events of the transmission line at each time point. These historical data are cleaned and sorted by a data processing tool (such as the Pandas library in Python) to remove outliers and missing values to ensure the accuracy of the data. Then, a mathematical fitting method, such as the least squares method, is used to fit the time series change curve. This process can be completed using a curve fitting algorithm (such as curve_fit in Scipy). A suitable data fitting model (such as an exponential decay model or a linear regression model) is selected to fit the historical breakage rate data to obtain a trend curve of the breakage rate changing with time. This trend curve can reflect the change of the breakage rate of the transmission line within a certain time period, and finally generate a trend curve of the change of the breakage rate of the transmission line.
[0053] Preferably, the growth or decline rate of the breakage rate corresponding to the area where the transmission line is located is determined through the trend curve of the change of the breakage rate of the transmission line. In an embodiment of the present invention, by analyzing the derivative of the curve according to the previously obtained trend curve of the change of the breakage rate of the transmission line, the change rate of the breakage rate is determined. First, a numerical derivative is taken of the trend curve (for example, using the difference method or the derivative calculation formula) to obtain the change rate of the breakage rate at each time point. If the curve shows an upward trend, it means the breakage rate is increasing; if the curve shows a downward trend, it means the breakage rate is decreasing. The calculated rate value can be judged by a set threshold. If the rate is greater than the preset growth rate threshold, it is considered that the breakage rate is increasing rapidly; if the rate is less than the preset decline rate threshold, it is considered that the breakage rate is decreasing slowly. Through this analysis, the change trend of the breakage rate in the area where the transmission line is located can be clearly understood, and finally the growth or decline rate of the breakage rate corresponding to the area where the transmission line is located is obtained.
[0054] Preferably, a breakage fault analysis is performed on the corresponding poles and towers around the transmission line based on the growth or decline rate of the breakage rate corresponding to the area where the transmission line is located. If the growth or decline rate of the breakage rate is greater than or equal to the preset threshold, it is determined that there is a breakage fault in the corresponding transmission line pole and tower; otherwise, it is determined that there is no breakage fault in the corresponding transmission line pole and tower to obtain the result of the external breakage fault of the transmission line pole and tower. In an embodiment of the present invention, by combining geographical information and historical damage data of poles and towers around a transmission line according to the growth or decline rate of the previously obtained damage rate, a fault analysis of the poles and towers is carried out. First, according to the change rate of the damage rate in the area where the pole or tower is located, a certain algorithm (such as linear regression, support vector machine, etc.) is used to evaluate the risk of each pole and tower. If the growth or decline rate of the damage rate in this area exceeds a preset threshold (such as the growth rate exceeds 0.2% per month), it is determined that the poles and towers in this area have a relatively high risk of damage, and then it is determined that these poles and towers have external damage faults. According to the analysis results, fault identification will be carried out on the poles and towers around the transmission line, and the result of "there is a damage fault" or "there is no damage fault" will be output, and finally the result of external damage faults of the transmission line poles and towers is obtained.
[0055] Preferably, a convolutional neural network is used to identify and analyze the internal safety faults of the current components and voltage components of the transmission line poles and towers to obtain the results of internal electrical parameter faults of the transmission line poles and towers; In an embodiment of the present invention, the current and voltage data of the poles and towers are collected in real time through sensors installed on the transmission line poles and towers, and the current and voltage data will be transmitted to the data processing system through wireless communication technology (such as a solution combining the Beidou positioning system and the wireless sensor network). Subsequently, a convolutional neural network (CNN) is used to identify and analyze the current and voltage data. Specifically, a trained convolutional neural network model is used, which is specifically used to analyze the current and voltage data of electrical equipment and identify possible electrical faults, including whether there is overload (that is, the current gradually increases and the voltage gradually decreases), short circuit (that is, the current suddenly surges and the voltage suddenly drops) and other safety faults in the transmission line. The input data is processed by the convolutional layer and the pooling layer to extract the characteristics of the current and voltage signals, and then classified and output through the fully connected layer. If the current or voltage fluctuates abnormally, it is determined that the pole and tower has an internal electrical fault, and the corresponding fault type is output, and finally the result of internal electrical parameter faults of the transmission line poles and towers is obtained.
[0056] Preferably, the results of external damage faults of the transmission line poles and towers and the results of internal electrical parameter faults of the transmission line poles and towers are combined to obtain the results of safety fault identification of the transmission line poles and towers.
[0057] In an embodiment of the present invention, by combining the previously obtained results of external factor damage faults with the results of internal factor electrical parameter faults identified by a convolutional neural network, first, the results of the two are subjected to data fusion, and a decision tree algorithm, weighted average or other suitable fusion method is used to synthesize the external and internal factor fault information. If one or both results indicate that there is a fault in the pole tower, it is finally determined that the pole tower has a safety fault; if both the external factor fault result and the internal factor fault result indicate that the pole tower has no fault, it is determined that the pole tower is safe. This result can not only identify whether there is a fault in the pole tower, but also further distinguish whether the nature of the fault is caused by external environmental factors or electrical factors, and finally obtain the identification result of the safety fault of the transmission line pole tower.
[0058] Furthermore, the use of the convolutional neural network to perform internal factor safety fault identification and analysis on the current component of the transmission line pole tower and the voltage component of the transmission line pole tower includes: Performing time series synchronization processing on the current component of the transmission line pole tower and the voltage component of the transmission line pole tower to obtain the corresponding pole tower current component sequence and pole tower voltage component sequence within the same time series range; In an embodiment of the present invention, by performing time series synchronization processing on the current component of the transmission line pole tower and the voltage component of the transmission line pole tower, first, the current and voltage signal data of each transmission line pole tower are collected. During the collection process, high-precision current and voltage sensors are used to monitor the electrical parameters of each pole tower on the line in real time, and the collected current and voltage signals are time series aligned through a synchronous sampling device. The specific operation is to calibrate through the time stamp and the synchronous signal to ensure that the acquisition time points of all pole tower current and voltage signals are consistent within the same time series range, so that the current and voltage data are completely aligned in the time domain. After the time series synchronization processing is completed, the corresponding pole tower current component sequence and pole tower voltage component sequence within the same time series range can be obtained.
[0059] Preferably, frequency domain statistical analysis of the pole tower electrical parameters is performed on the corresponding pole tower current component sequence and pole tower voltage component sequence within the same time series range to obtain the frequency domain statistical characteristics corresponding to the transmission line pole tower electrical parameters, including the frequency components, harmonic contents, and transient change characteristics corresponding to the current and voltage; In an embodiment of the present invention, through frequency-domain statistical analysis of the corresponding tower current component sequence and tower voltage component sequence within the same time sequence range, first, frequency-domain conversion is performed on the synchronized current and voltage sequences through fast Fourier transform (FFT). The current and voltage signals are divided into different frequency components in the frequency domain, and the FFT algorithm can extract these frequency components. For the electrical parameters of each transmission line, by analyzing the amplitude spectrum in the frequency domain, the main frequency components and harmonic contents are extracted. Through frequency-domain analysis, the low-frequency components, intermediate-frequency components, and high-frequency components in the current and voltage signals are calculated, and the existing harmonic components are particularly identified. Further, statistical methods are used to evaluate the intensity, phase, and harmonic distortion of the components in each frequency band to obtain frequency-domain statistical features, and finally, the frequency-domain statistical features corresponding to the electrical parameters of the transmission line tower are obtained.
[0060] Preferably, based on the frequency-domain statistical features corresponding to the electrical parameters of the transmission line tower, instantaneous mutation analysis is performed on the corresponding tower current component sequence and tower voltage component sequence within the same time sequence range to obtain the instantaneous mutation distribution features corresponding to the electrical parameters of the transmission line tower; In an embodiment of the present invention, through instantaneous mutation analysis of the tower current component sequence and voltage component sequence based on the frequency-domain statistical features, first, the instantaneous change regions in the signals are extracted through the frequency-domain statistical features. The purpose of instantaneous mutation analysis is to identify sudden events in the current and voltage signals, such as sharp increases, decreases, or fluctuations in current or voltage, which are usually caused by line failures. Using wavelet transform or time-domain difference method, mutation detection is performed on the current and voltage signals. Specifically, the sliding window technique is adopted to gradually analyze the changes in current and voltage in each time period, calculate their change rates and change amplitudes in this time period, and identify whether the instantaneous change exceeds a predetermined threshold. By extracting the mutation intervals, the distribution features of the mutation phenomena in the transmission line can be accurately obtained, including the time, amplitude, and duration of the mutation, and finally, the instantaneous mutation distribution features corresponding to the electrical parameters of the transmission line tower are obtained.
[0061] Preferably, a convolutional neural network is used to perform internal cause safety fault identification analysis on the instantaneous mutation distribution features corresponding to the electrical parameters of the transmission line tower, so as to input the instantaneous mutation distribution features corresponding to the electrical parameters of the transmission line tower into the convolutional neural network to construct a tower electrical parameter line fault identification model, and output the overload and short-circuit faults corresponding to the transmission line tower to obtain the internal cause electrical parameter fault results of the transmission line tower.
[0062] In the embodiment of the present invention, a convolutional neural network (CNN) is used to perform fault identification and analysis on the instantaneous mutation distribution characteristics of electrical parameters. First, the mutation characteristics of current and voltage extracted from the instantaneous mutation analysis are input into the convolutional neural network model. This model first performs multi-layer convolutional operations on the input mutation characteristics to learn the spatial characteristics of current and voltage mutations. Then, the pooling layer is used to further reduce the data dimension and improve the efficiency of the model. Next, the fully connected layer is used to convert the feature map into the determination result of electrical parameter faults. At this time, the convolutional neural network performs in-depth learning on the mutation distribution characteristics of electrical parameters through the trained model, and automatically identifies whether there are safety faults such as overload (i.e., the current gradually increases and the voltage gradually decreases) and short circuit (i.e., the current suddenly surges and the voltage suddenly drops) in the transmission line. Through network training, the model can be continuously optimized based on historical data, so as to realize the prediction and alarm of future fault events. When the model outputs a signal of overload or short circuit fault, an alarm will be automatically generated to prompt the safety risk of the transmission line, and finally the internal electrical parameter fault result of the transmission line tower will be obtained.
[0063] Furthermore, the safety fault location and early warning module includes the following functions: Integrate and deploy the Beidou positioning module on the corresponding towers around the transmission line; In the embodiment of the present invention, by integrating and deploying the Beidou positioning module on each tower of the transmission line, to ensure the positioning accuracy and stability, each tower should be equipped with a set of integrated Beidou receiving modules, which have the ability to receive satellite signals in real time. This Beidou positioning module should be able to maintain high-precision positioning under strong electromagnetic interference, complex environments, etc. During the actual deployment process, first, according to the path of the transmission line and the specific location of the tower, select a suitable installation location and ensure that the module can maintain a continuous and stable satellite connection. The power supply of the module is powered by an external solar panel and a storage battery to ensure 24-hour all-weather operation. Each positioning module is connected to the central control platform through a wireless communication network (such as 5G, LoRa, etc.) to transmit real-time positioning data.
[0064] Preferably, the Beidou positioning module is used to perform fault location and early warning on the transmission line towers corresponding to the safety fault identification results of the transmission line towers with safety faults, so as to obtain the fault warning position of the transmission line towers; In an embodiment of the present invention, the deployed Beidou positioning module is used to monitor each transmission line tower in real time, identify safety faults, and determine whether there are transmission line towers with safety faults in the previously identified safety fault identification results of the transmission line towers. If so, the Beidou positioning module will be automatically activated for fault location. When a fault is identified, the Beidou positioning module will obtain the specific tower position where the fault occurs and transmit the coordinates and fault information of this fault position to the central monitoring system through a wireless network. At this time, the system processes and analyzes the data according to the input algorithm model, judges the severity of the fault, generates corresponding early warning information, marks the transmission line towers with safety faults, and issues an early warning to relevant operators, and finally locates the early warning position of the transmission line tower fault.
[0065] Preferably, obtain the known positions of rescue teams, and perform repair positioning calculations on the known positions of rescue teams based on the early warning position of the transmission line tower fault to obtain the distance and azimuth between the transmission line fault point and the known position points, and notify the execution of the corresponding transmission line fault early warning repair work.
[0066] In an embodiment of the present invention, after receiving the early warning of the transmission line tower fault, the position information of the known rescue teams is further obtained. The positions of these rescue teams can be tracked in real time through the Beidou positioning module or other GPS positioning technologies. According to the early warning position of the faulty tower, the distance and azimuth from the rescue team to the fault position will be calculated by triangulation using the positions of the known rescue teams and the coordinates of the faulty tower. This calculation takes into account terrain factors and transportation routes to ensure high accuracy of the calculated distance and azimuth. Based on the calculation results, the system sends repair instructions to each rescue team, guiding them the shortest path and real-time traffic information to ensure timely repair work. At the same time, the rescue team members can receive repair information in real time through mobile terminals and accurately reach the fault point for repair under the guidance of the Beidou positioning system. They can also adjust the early warning and repair scheduling plan according to the real-time feedback during the repair process to optimize the repair efficiency and fault recovery speed, and finally notify the execution of the corresponding transmission line fault early warning repair work.
[0067] Therefore, from any perspective, the embodiments should be regarded as exemplary and non-limiting.
