Description

Technical Field

[0001] The present application belongs to the field of data analysis, and specifically to a method and system for planning mobile routes for intensive power transmission channels based on operation and maintenance information. Background Art

[0002] In the field of intelligent power system operation and maintenance, mobile operating equipment (such as inspection drones and robots) face severe safety challenges when traversing dense transmission corridors. These corridors are commonly characterized by high-density layouts such as multiple circuits on the same tower, AC / DC hybrid systems, and compact corridors. This leads to highly complex spatial electromagnetic field distribution. Existing route planning technologies have the following shortcomings: Without fault impact analysis, it is difficult to identify potential risks in the inspection route in a timely manner, which may cause equipment or personnel to operate in high-risk areas, thereby increasing the hidden dangers of personal safety and equipment damage; in dense transmission channels, the lines are close to each other, and a fault on a certain route may affect the stability of the adjacent lines. The lack of fault impact analysis will cause this chain reaction to be ignored, resulting in the expansion of the fault and the aggravation of the impact range; the failure to analyze the fault impact of each inspection route in advance makes it difficult to quickly determine the affected areas and key points when a fault occurs, delaying the emergency repair time, reducing the efficiency of emergency response, and affecting the overall stable operation of the transmission system; route planning does not take the impact of faults into consideration, which may cause the selected route to have a higher risk in actual operation, increase the difficulty of operation and the probability of fault occurrence, and reduce the effectiveness and safety of equipment operation; failure to analyze the impact of faults may result in hidden dangers not being detected and handled in a timely manner, and the frequency and severity of faults will increase, thereby increasing maintenance costs and power outage losses, and reducing the economic benefits of the system; in order to solve the problems raised by this background technology, the present application designs a method and system for mobile route planning of dense transmission channels based on operation and maintenance information. Summary of the Invention

[0003] In response to the above-mentioned technical deficiencies, this application proposes a method and system for planning mobile routes for dense transmission channels based on operation and maintenance information.

[0004] To solve the above technical problems, the present invention adopts the following technical solution: This application provides a method for planning a mobile route for a dense transmission channel based on operation and maintenance information, which includes the following specific steps: S1.

Conduct risk impact analysis on each moving route based on the risk analysis results of each moving route and the channel density and layout status data of each moving route; S5. Obtain the optimal moving route based on the hazard impact analysis results of each moving route, and use the obtained optimal route as the equipment operation route.

[0005] It should be noted that, as a preferred technical solution for the method of planning the mobile route of a dense transmission channel based on operation and maintenance information, the specific steps of S1 are: the environmental information data includes terrain complexity data and visibility data, and the method for obtaining the terrain complexity data is: obtaining the DEM data of the required area from a professional geographic data platform, processing the DEM data of the required area, and calculating the required terrain slope value data; obtaining the remote sensing image data of the required area, performing image processing on the data, and identifying the water system distribution data of the required area; obtaining the visibility data of the required area during future equipment operation through a meteorological website, application or API of a meteorological station; obtaining the data on the impact of electromagnetic interference on each section of the transmission channel in each historical mobile route is: obtaining the coupling voltage status data of each section of the transmission channel in each historical mobile route from historical operation and maintenance records; obtaining the channel density and layout status data of each mobile route is: obtaining the line spacing value of each section of the transmission channel in each mobile route from the engineering research report; obtaining the data on the number of multiple lines connected to a single base tower from the tower design report of each section of the transmission channel in each mobile route.

[0006] It should be noted that, as a preferred technical solution for the method for planning the mobile route of a dense transmission channel based on operation and maintenance information, S2 includes the following specific steps: S21, performing terrain influence analysis corresponding to each transmission channel section in each moving route based on terrain complexity data corresponding to each transmission channel section in each moving route; S22. performing a meteorological impact analysis corresponding to each transmission channel section in each moving route based on the visibility data corresponding to each transmission channel section in each moving route; S23. Obtain environmental impact analysis results for each moving route based on the terrain impact analysis results and meteorological impact analysis results corresponding to each section of the power transmission channel in each moving route.

[0007] It should be noted that, as a preferred technical solution for the method for planning the mobile route of intensive transmission channels based on operation and maintenance information, the specific steps of S21 are: based on the terrain complexity data corresponding to each section of the transmission channel in each mobile route, the terrain influence analysis corresponding to each section of the transmission channel in each mobile route is performed; wherein the terrain influence analysis method corresponding to each section of the transmission channel in each mobile route is: obtaining the terrain slope data and water system distribution data corresponding to each section of the transmission channel in each mobile route; dividing the difference between the maximum value and the minimum value of the terrain slope of each section of the transmission channel in each mobile route by the difference between the average value and the minimum value of the terrain slope, and quantifying the terrain influence. The slope changes in each section of the transmission channel in each mobile route; the water system distribution density corresponding to each section of the transmission channel in each mobile route is divided by the reference water system distribution density to quantify the water system complexity corresponding to each section of the transmission channel in each mobile route; the slope changes in each section of the transmission channel in each mobile route and the water system complexity are weighted and summed up to obtain the terrain influence analysis results corresponding to each section of the transmission channel in each mobile route; it should be noted here that the slope change and the water system complexity are superimposed, the weight is adjusted according to the project requirements, and the two key parameters of slope and water system are integrated to more comprehensively reflect the comprehensive impact of terrain on equipment operation.

[0008] It should be noted that, as a preferred technical solution for the method for planning mobile routes of dense transmission channels based on operation and maintenance information, the specific steps of S22 are: performing a meteorological impact analysis corresponding to each section of the transmission channel in each mobile route based on the visibility data corresponding to each section of the transmission channel in each mobile route; wherein the meteorological impact analysis process corresponding to each section of the transmission channel in each mobile route is: obtaining the visibility data corresponding to each section of the transmission channel in each mobile route; dividing the difference between the visibility data corresponding to each section of the transmission channel in each mobile route and the minimum allowable visibility value by the reference visibility difference, and quantitatively predicting the degree of deviation of the visibility of the equipment from the minimum allowable value when operating in each section of the transmission channel; it should be noted here that the reason for selecting visibility to analyze the meteorological impact of each section of the transmission channel in each mobile route is: when the equipment operates in a dense transmission channel, visibility is the core factor that directly determines the safety and effectiveness of the equipment operation. When the visibility is too low, the effectiveness of the data collected during the equipment operation will be greatly reduced.

[0009] It should be noted that, as a preferred technical solution for the mobile route planning method of dense transmission channels based on operation and maintenance information, the specific steps of S23 are: obtaining the terrain impact analysis results and meteorological impact analysis results corresponding to each section of the transmission channel in each mobile route, weighting and summing the terrain impact analysis results and meteorological impact analysis results corresponding to each section of the transmission channel in each mobile route to obtain the environmental impact analysis results corresponding to each section of the transmission channel in each mobile route, summing and averaging the environmental impact analysis results corresponding to each section of the transmission channel in each mobile route to obtain the environmental impact analysis results of each mobile route; it should be noted here that, by comprehensively evaluating the degree of influence of equipment operation due to external environmental factors on equipment operation in each mobile route by combining the difficulty and danger of equipment operation in each mobile route in the dense transmission channel, and performing reasonable weight distribution on them, the accuracy of environmental impact analysis is improved.

Acquire coupling voltage status data for each transmission channel section in each historical moving route, and perform electromagnetic interference impact analysis on each transmission channel section in each historical moving route based on the coupling voltage status data for each transmission channel section in each historical moving route. The electromagnetic interference impact analysis method is as follows: divide the difference between the maximum and minimum coupling voltage fluctuations for each transmission channel section in each historical moving route by a reference coupling voltage fluctuation value to quantify the fluctuation stability of the coupling voltage for each transmission channel section in each historical moving route; divide the average coupling voltage for each transmission channel section in each historical moving route by the reference coupling voltage to quantify the degree of interference of each transmission channel section in each moving route to the device; and weight the fluctuation stability of the coupling voltage for each transmission channel section in each moving route and the degree of interference to the device, and then add them together to obtain an electromagnetic interference impact analysis result for each transmission channel section in each moving route. It should be noted that the electromagnetic interference impact is analyzed by superimposing the fluctuation stability of the coupling voltage with the degree of interference to the device, and by reasonably assigning weights to the fluctuation stability of the coupling voltage and the degree of interference to the device, thereby improving the accuracy of the electromagnetic interference impact analysis result. S312. Obtain the electromagnetic interference impact analysis results of each section of the transmission channel in each mobile route, sum up the electromagnetic interference impact analysis results of each section of the transmission channel in each mobile route, and then calculate the average value to obtain the electromagnetic interference impact analysis results of each mobile route; it should be noted here that by summing up the electromagnetic interference impact analysis results of each section of the transmission channel in each mobile route and then calculating the average value, the influence of the more extreme results in the electromagnetic interference impact analysis results on the overall results can be removed, thereby improving the accuracy of the electromagnetic interference impact analysis results.

[0012] It should be noted that, as a preferred technical solution for the intensive transmission channel mobile route planning method based on operation and maintenance information, the specific steps of S32 are: obtaining the electromagnetic interference impact analysis results of each mobile route, and weighting the electromagnetic interference impact analysis results of each mobile route with the environmental impact analysis results, and adding them together to obtain the hazard analysis results of each mobile route; it should be noted here that by comprehensively analyzing the external environmental influencing factors and superimposing the interference of the transmission channel itself on the equipment to analyze and obtain the hazard analysis results of the equipment in each mobile route, through reasonable weight distribution, the hazard in the mobile route can be analyzed more accurately, thereby improving the safety of equipment operation.

[0013] It should be noted that, as a preferred technical solution for the intensive transmission channel mobile route planning method based on operation and maintenance information, the specific steps of S4 are: obtaining the hazard analysis results of each mobile route, the average value data of channel line spacing and the data on the number of multiple lines hung on a single-base tower, dividing the difference between the average value data of the channel line spacing of each mobile route and the minimum value of the channel line spacing by the reference channel line spacing difference, and quantifying the risk level of each mobile route due to inappropriate channel line spacing value; dividing the data on the number of multiple lines hung on a single-base tower on each mobile route by the reference data on the number of multiple lines hung on a single-base tower, and quantifying the degree of impact spread caused by failures of multiple lines hung on a single-base tower in each mobile route; dividing the data on the number of multiple lines hung on a single-base tower on each mobile route by the reference data on the number of multiple lines hung on a single-base tower, and quantifying the degree of impact spread caused by failures of multiple lines hung on a single-base tower in each mobile route; dividing the data on the number of multiple lines hung on a single-base tower on each mobile route by the reference data on the number of multiple lines hung on a single-base tower The degree of risk generated is multiplied by the degree of diffusion of the impact caused by the failure of multiple lines hung on a single-base tower, and the degree of diffusion of the dangerous impact in each moving route is quantified; the degree of diffusion of the dangerous impact in each moving route is multiplied by the hazard analysis result of each moving route to obtain the hazard impact analysis result of each moving route; it should be noted here that by multiplying the risk generated by inappropriate channel line spacing value with the degree of diffusion of the impact caused by the failure of a single-base tower, the mutual influence between the risk generated by inappropriate channel line spacing value in the moving route and the degree of diffusion of the impact caused by the failure of a single-base tower is quantified. This is because when the channel line spacing value is inappropriate, if a dangerous situation occurs, the more lines are connected to the tower, the greater the impact.

[0014] It should be noted that, as a preferred technical solution for the intensive transmission channel mobile route planning method based on operation and maintenance information, the specific steps of S5 are: obtaining the hazard impact analysis results of all mobile routes, arranging the hazard impact analysis results of all mobile routes in ascending order, and taking the mobile route corresponding to the smallest hazard impact analysis result as the optimal mobile route, and using this route as the equipment operation route; it should be noted here that the hazard impact of each mobile route is arranged in descending order to obtain the safest route, thereby improving the safety of equipment operation and reducing the impact of dangerous situations in equipment operation.

[0015] A dense transmission channel mobile route planning system based on operation and maintenance information is implemented based on the above-mentioned dense transmission channel mobile route planning method based on operation and maintenance information, and specifically includes a mobile route data acquisition module, an environmental impact analysis module, a route hazard analysis module, a hazard impact analysis module, and an optimal route analysis module; the mobile route data acquisition module is used to obtain environmental information data corresponding to each section of the transmission channel in each mobile route, channel density and layout status data, and impact data caused by electromagnetic interference on each section of the transmission channel in each historical mobile route; The environmental impact analysis module is used to perform environmental impact analysis on each moving route based on the environmental information data corresponding to each section of the power transmission channel in each moving route; The route hazard analysis module is used to perform hazard analysis on each moving route based on the impact data of electromagnetic interference on each transmission channel in each historical moving route and the environmental impact analysis results of each moving route; The hazard impact analysis module is used to perform hazard impact analysis on each moving route based on the hazard analysis results of each moving route and the channel density and layout status data of each moving route; The optimal route analysis module is used to obtain the optimal moving route based on the hazard impact analysis results of each moving route, and use the obtained optimal route as the equipment operation route.

[0020] In order to better understand the present application, various aspects of the present application will be described in more detail with reference to the accompanying drawings.

[0021] In order to solve the technical problems raised in the background technology, this application provides a preferred embodiment: The specific contents of this embodiment are: like Figure 1 As shown in FIG, a method for planning a mobile route for a dense transmission channel based on operation and maintenance information includes the following specific steps: S1. Obtaining environmental information data, channel density and layout status data corresponding to each section of the transmission channel in each moving route, and historical data on the impact of electromagnetic interference on each section of the transmission channel in each moving route; In this embodiment, the specific steps of S1 are: the environmental information data includes terrain complexity data and visibility data, and the terrain complexity data is obtained by: obtaining the required area DEM (DEM is a format that represents the elevation data of the earth's surface in grid form) data from a professional geographic data platform (such as the Geospatial Data Cloud, the National Glacier Permafrost Desert Science Data Center, and the Zenodo Scientific Data Set), and then using GIS (such as QGIS or ArcGIS) software to analyze and process the required area DEM data to calculate the required terrain slope value data; obtaining the required area remote sensing image data (such as Sentinel-2 or Landsat data), performing image processing on the required area remote sensing image data, and identifying the required area water system distribution data; the visibility data is obtained by: Obtain visibility data for future equipment operations in the required area through weather websites, applications, or APIs from weather stations; obtain data on the impact of electromagnetic interference on each section of the transmission channel in each historical moving route by obtaining the coupling voltage status data of each section of the transmission channel in each historical moving route from historical operation and maintenance records; obtain data on the channel density and layout status of each moving route by obtaining the line spacing values ​​of each section of the transmission channel in each moving route from the engineering research report (for example, in a certain project, when a 1000kV AC line (double circuits on the same tower) is parallel to a ±800kV DC line, the minimum spacing should be 62 meters), and obtain the average line spacing data of each moving route channel through the line spacing values; obtain data on the number of multiple lines connected to a single tower from the tower design report of each section of the transmission channel in each moving route. S2. Analyze the environmental impact of each moving route based on the environmental information data corresponding to each section of the power transmission channel in each moving route; S21, performing terrain influence analysis corresponding to each transmission channel section in each moving route based on terrain complexity data corresponding to each transmission channel section in each moving route; In this embodiment, S21 includes the following specific steps: based on the terrain complexity data corresponding to each section of the transmission channel in each moving route, a terrain influence analysis corresponding to each section of the transmission channel in each moving route is performed; wherein the terrain influence analysis corresponding to each section of the transmission channel in each moving route is performed in the following manner: obtaining terrain slope data and water system distribution data corresponding to each section of the transmission channel in each moving route; dividing the difference between the maximum value and the minimum value of the terrain slope of each section of the transmission channel in each moving route by the difference between the average value and the minimum value of the terrain slope, to quantify the slope change in each section of the transmission channel in each moving route; dividing the water system distribution density corresponding to each section of the transmission channel in each moving route by the reference water system distribution density, to quantify the water system complexity corresponding to each section of the transmission channel in each moving route; weighting the slope change in each section of the transmission channel in each moving route and the water system complexity, and thereby obtaining the water system complexity of each section of the transmission channel in each moving route. Results of terrain impact analysis corresponding to each section of the transmission channel in the dynamic route; it should be noted that the normalization processing method of "(maximum slope - minimum slope) / (average slope - minimum slope)" is used to effectively eliminate the impact of scale differences; the ratio of the slope extreme difference to the mean difference reflects the slope fluctuation amplitude while avoiding the interference of absolute elevation, which is consistent with the core principle of slope in topographic maps (slope equals elevation difference / horizontal distance); the ratio of water system distribution density to reference density is calculated to achieve horizontal comparability of data from different watersheds; the slope change is superimposed on the water system complexity, and the weight can be adjusted according to engineering needs (for example, the water system weight can be increased in areas prone to debris flows, while the slope indicator is emphasized in steep slope areas). This flexibility is significantly better than the traditional lookup method, integrating two key parameters: slope (topographic element) and water system (hydrological element), and more comprehensively reflecting the comprehensive impact of terrain on equipment operation than a single indicator (such as the strip method).

[0022] S22. performing a meteorological impact analysis corresponding to each transmission channel section in each moving route based on the visibility data corresponding to each transmission channel section in each moving route; In this embodiment, S22 includes the following specific steps: performing a meteorological impact analysis on each transmission channel section in each moving route based on visibility data corresponding to each transmission channel section in each moving route; wherein the meteorological impact analysis process for each transmission channel section in each moving route comprises: obtaining visibility data corresponding to each transmission channel section in each moving route; dividing the difference between the visibility data corresponding to each transmission channel section in each moving route and the minimum allowable visibility value by a reference visibility difference value, and quantitatively predicting the degree of deviation of the visibility of the equipment from the minimum allowable value when operating in each transmission channel section. It should be noted that visibility is selected to analyze the meteorological impact of each transmission channel section in each moving route because, when equipment operates in dense transmission channels, visibility is a core factor that directly determines the safety and effectiveness of equipment operation. Once visibility is too low, the equipment cannot meet the basic obstacle avoidance analysis time, and the probability of collision during equipment operation is greatly increased. At the same time, due to the low visibility, the effectiveness of the data collected during equipment operation is also greatly reduced.

[0023] S23. Obtaining environmental impact analysis results for each moving route based on the terrain impact analysis results and meteorological impact analysis results corresponding to each transmission channel section in each moving route; In this embodiment, S23 includes the following specific steps: obtaining terrain impact analysis results and meteorological impact analysis results corresponding to each section of the transmission channel in each mobile route, weighting and summing the terrain impact analysis results and meteorological impact analysis results corresponding to each section of the transmission channel in each mobile route to obtain the environmental impact analysis results corresponding to each section of the transmission channel in each mobile route, summing and averaging the environmental impact analysis results corresponding to each section of the transmission channel in each mobile route to obtain the environmental impact analysis results of each mobile route; it should be noted here that the degree of impact of equipment operation due to external environmental factors on each mobile route in the dense transmission channel is comprehensively assessed by combining the difficulty and danger of equipment operation on each mobile route, and reasonably allocating weights to them, thereby improving the accuracy of the environmental impact analysis.

[0024] S3. Conduct risk analysis on each moving route based on historical data on the impact of electromagnetic interference on each transmission channel in each moving route and the environmental impact analysis results of each moving route; In this embodiment, the specific steps of S3 are: S31. Analyze the impact of electromagnetic interference on each moving route based on historical data on the impact of electromagnetic interference on each transmission channel in each moving route; In this embodiment, the specific steps of S31 are: S311. Obtain coupling voltage status data of each transmission channel section in each historical moving route, and perform electromagnetic interference impact analysis on each transmission channel section in each historical moving route based on the coupling voltage status data of each transmission channel section in each historical moving route, wherein the electromagnetic interference impact analysis method is as follows: divide the difference between the maximum and minimum coupling voltage fluctuations of each transmission channel section in each historical moving route by the reference coupling voltage fluctuation value to quantify the fluctuation stability of the coupling voltage of each transmission channel section in each mobile route; divide the average coupling voltage of each transmission channel section in each historical moving route by the reference coupling voltage to quantify the degree of interference of each transmission channel section in each mobile route to the equipment; weight the fluctuation stability of the coupling voltage of each transmission channel section in each mobile route and the degree of interference to the equipment and add them to obtain the electromagnetic interference impact analysis result of each transmission channel section in each mobile route; It should be noted here that in the process of power transmission, especially high-voltage transmission lines, the electromagnetic waves they generate may be coupled to other equipment or lines through power lines, conductors or other adjacent conductive media. This coupling voltage is through electromagnetic induction or electromagnetic coupling effect. The strong electric and magnetic fields generated by high-voltage power lines in dense transmission channels may be coupled to nearby equipment or electrical systems through adjacent conductors or power facilities (such as power towers, overhead lines, underground cables, etc.), causing interference to nearby equipment or electrical systems (such as magnetic field interference and electric field interference. Magnetic field interference: When high-voltage current passes through the transmission line, the change in current generates a magnetic field. This magnetic field affects the surrounding conductors, especially when high current flows, the magnetic field is stronger; electric field interference: Voltage changes on the transmission line will generate an electric field on nearby conductors, thereby inducing coupling voltage). The coupling voltage may have an adverse effect on surrounding electronic equipment, control systems, or communication equipment (such as electrical noise, signal interference, or equipment failure). When the coupling voltage is too large, it may cause voltage fluctuations, overload, or damage to power equipment (such as transformers, switchgear, etc.); the electromagnetic interference impact is analyzed by superimposing the fluctuation stability of the coupling voltage on the degree of interference to the equipment, and by reasonably allocating weights to the fluctuation stability of the coupling voltage and the degree of interference to the equipment, the accuracy of the electromagnetic interference impact analysis results is improved.

[0025] S312. Obtain the electromagnetic interference impact analysis results of each section of the transmission channel in each mobile route, sum up the electromagnetic interference impact analysis results of each section of the transmission channel in each mobile route, and then calculate the average value to obtain the electromagnetic interference impact analysis results of each mobile route; it should be noted here that by summing up the electromagnetic interference impact analysis results of each section of the transmission channel in each mobile route and then calculating the average value, the influence of the more extreme results in the electromagnetic interference impact analysis results on the overall results can be removed, and at the same time, the trend of the electromagnetic interference impact analysis results can be quantified, and the fluctuation range of the electromagnetic interference impact analysis result data can be smoothed, thereby improving the accuracy of the electromagnetic interference impact analysis results of each mobile route.

[0026] S32. Perform risk analysis on each movement route based on the electromagnetic interference impact analysis results and environmental impact analysis results of each movement route; In this embodiment, the specific steps of S32 are: obtaining the electromagnetic interference impact analysis results of each mobile route, and weighting the electromagnetic interference impact analysis results of each mobile route with the environmental impact analysis results to obtain the hazard analysis results of each mobile route; it should be noted here that complex terrain and low visibility environment constitute external interference when the equipment is operating, which makes the equipment face higher risks and uncertainties during operation, which may cause equipment failure and affect the normal operation of the equipment; the coupling voltage generated by the transmission channel itself may also interfere with the operation of the equipment, especially when high-voltage current passes through, electromagnetic interference will affect the normal operation of the equipment, and may even cause equipment failure or data errors, reducing the safety and efficiency of the equipment during operation; by comprehensively analyzing the external environmental influencing factors and superimposing the interference of the transmission channel itself on the equipment to analyze the hazard analysis results of the equipment in each mobile route, through reasonable weight distribution, the hazard in the mobile route can be analyzed more accurately, thereby improving the safety of the equipment during operation.

[0027] S4. Conduct risk impact analysis on each moving route based on the risk analysis results of each moving route and the channel density and layout status data of each moving route; In this embodiment, the specific steps of S4 are: obtaining the hazard analysis results of each moving route, the average value data of the channel line spacing, and the number of multiple lines hung on a single-base tower, dividing the difference between the average value data of the channel line spacing of each moving route and the minimum value of the channel line spacing by the reference channel line spacing difference, and quantifying the risk level of each moving route due to inappropriate channel line spacing value; dividing the number data of multiple lines hung on a single-base tower on each moving route by the reference number data of multiple lines hung on a single-base tower, and quantifying the impact spread of a failure of multiple lines hung on a single-base tower in each moving route; multiplying the risk level of each moving route due to inappropriate channel line spacing value by the impact spread of a failure of multiple lines hung on a single-base tower, and quantifying the risk spread of each moving route; multiplying the risk spread of each moving route by the hazard analysis result of each moving route to obtain the hazard impact analysis result of each moving route; It should be noted that the reason for selecting the average value data of the channel line spacing and the number data of multiple lines hung on a single-base tower to analyze the hazard impact is that sufficient safety is required between the channel lines. Distance (e.g. double-circuit vertical arrangement requires 12-14m horizontal spacing, while the same-side vertical arrangement (F-type tower) can be narrowed to 6-8m). Too small channel line spacing will increase the risk of cascading failures (e.g. collapse or disconnection of a tower may affect adjacent lines); in the data on the number of multiple lines connected to a single tower on each mobile route, multiple lines refers to more than or equal to 2 lines. When a single tower is connected to multiple lines, it can also be called a shared tower. This shared tower is a typical vulnerable point in a dense transmission channel. Its failure may cause all connected lines to stop operating at the same time (e.g. when a single tower is connected to a large number of lines, it may cause all connected lines to stop operating at the same time). When the number of lines connected to a tower is equal to 3, if a single tower fails, the probability of a complete outage caused by the failure will increase by 4.7 times); by multiplying the risk caused by inappropriate channel line spacing values ​​with the degree of diffusion of the impact caused by a single tower failure, the mutual influence of the risk caused by inappropriate channel line spacing values ​​in the moving route and the degree of diffusion of the impact caused by a single tower failure is quantified. This is because when the channel line spacing value is inappropriate, if a dangerous situation occurs (such as collision and tower collapse), the more lines connected to the tower, the greater the impact.

[0028] S5. Obtain the optimal moving route based on the hazard impact analysis results of each moving route, and use the obtained optimal route as the equipment operation route.

[0029] like Figure 2As shown, in this embodiment, the specific steps of S5 are: obtaining the hazard impact analysis results of all moving routes, arranging the hazard impact analysis results of all moving routes in ascending order, and taking the moving route corresponding to the smallest hazard impact analysis result as the optimal moving route, and using this route as the equipment operation route; it should be noted here that the hazard impact of each moving route is arranged in descending order to obtain the safest route, thereby improving the safety of equipment operation.

[0030] According to the above implementation content, this embodiment has the following advantages over the existing technology: this embodiment obtains the environmental information data, channel density and layout status data corresponding to each section of the transmission channel in each mobile route, and the impact data of electromagnetic interference on each section of the transmission channel in each historical mobile route; analyzes the dangerous impact of each mobile route based on the acquired data to obtain the optimal mobile route; analyzes the impact of each mobile route after a fault occurs, promptly identifies potential risks in the inspection route, and improves the effectiveness and safety of equipment operations; analyzes the impact of the fault on each inspection route in advance, and can quickly determine the affected areas and key points when a fault occurs, thereby improving the efficiency of emergency response and ensuring the overall stable operation of the transmission system.

[0031] like Figure 3 As shown, this embodiment also provides a dense transmission channel mobile route planning system based on operation and maintenance information, which is implemented based on the above-mentioned dense transmission channel mobile route planning method based on operation and maintenance information, and specifically includes a mobile route data acquisition module, an environmental impact analysis module, a route hazard analysis module, a hazard impact analysis module and an optimal route analysis module; the mobile route data acquisition module is used to obtain the environmental information data corresponding to each section of the transmission channel in each mobile route, the channel density and layout status data and the impact data of each section of the transmission channel in each historical mobile route due to electromagnetic interference; the environmental impact analysis module is used to analyze the impact of each mobile route on the environment; The environmental impact analysis of each mobile route is performed based on the environmental information data corresponding to each section of the transmission channel in the route; the route hazard analysis module is used to perform hazard analysis on each mobile route based on the impact data of electromagnetic interference on each section of the transmission channel in each historical mobile route and the environmental impact analysis results of each mobile route; the hazard impact analysis module is used to perform hazard impact analysis on each mobile route based on the hazard analysis results of each mobile route and the channel density and layout status data of each mobile route; the optimal route analysis module is used to obtain the optimal mobile route based on the hazard impact analysis results of each mobile route, and use the obtained optimal route as the equipment operation route.
