Description

Technical Field

[0001] This invention relates to the field of wildfire monitoring, and more specifically, to a method, apparatus, electronic device, and storage medium for monitoring wildfires in power grids. Background Technology

[0002] In recent years, with the increasing frequency of extreme weather events and the expansion of human activities, natural disasters such as forest fires and wildfires have posed a serious threat to the safe operation of power grids. In particular, transmission lines operating in forest areas and densely vegetated regions are prone to tripping, line breaks, and other accidents caused by wildfires, resulting in power supply interruptions and potentially even secondary disasters.

[0003] To address the aforementioned risks, various wildfire monitoring solutions have been proposed, primarily including satellite remote sensing monitoring, power line camera monitoring, and manual line inspection, achieving preliminary intelligent wildfire monitoring capabilities. However, satellite remote sensing monitoring currently relies mainly on geostationary satellites, and there is still room for improvement in timeliness and accuracy. Power line camera monitoring involves deploying cameras in key areas and using image recognition algorithms to identify wildfires; however, this method is limited by equipment deployment density and viewing angle, making it difficult to achieve full coverage, and the accuracy is greatly affected by environmental factors, posing risks of recognition delays and misjudgments. Manual line inspection involves manually patrolling the areas surrounding the power lines to discover and remove combustibles to prevent wildfires; however, this method is labor-intensive, inefficient, and unable to provide real-time response to sudden fires. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a method, device, electronic device and storage medium for monitoring wildfires in power grids, so as to achieve high-precision positioning of fire, automatic identification of fire-affected devices and linkage analysis between fire and restricted burning areas, which is conducive to quickly determining whether the fire involves restricted burning areas and reducing the burden of manual confirmation.

[0005] To achieve the above objectives, the technical solutions adopted in the embodiments of the present invention are as follows:

[0006] In a first aspect, the present invention provides a method for monitoring wildfires in power grids, the method comprising:

[0007] Fire data for the target area is obtained based on polar-orbiting satellites;

[0008] Based on the fire data and the power transmission line ledger data corresponding to the target area, determine the power grid equipment affected by the fire;

[0009] Based on the no-burning zone equipment corresponding to the target area, determine the no-burning zone corresponding to the target area;

[0010] The fire data, the power grid equipment affected by the fire, and the prohibited burning areas are overlaid on the map.

[0011] In an optional implementation, determining the power grid equipment affected by the fire based on the fire data and the transmission line ledger data corresponding to the target area includes:

[0012] Obtain the location of each fire point and the fire spread radius in the fire data, and construct a circular buffer zone with the fire point location as the center and the fire spread radius as the radius.

[0013] Based on the starting and ending coordinates of the transmission line in the transmission line ledger data, a straight line equation for the line is constructed;

[0014] If the line equation and the circular buffer zone have at least one intersection point, then a candidate tower adjacent to the intersection point is searched on the transmission line. If the geodesic distance between the candidate tower and the fire point is less than the fire spread radius, then the candidate tower is identified as the tower affected by the fire, and the transmission line, the tower affected by the fire, and the conductor segment where the tower affected by the fire are located are identified as the power grid equipment affected by the fire.

[0015] In an optional implementation, determining the power grid equipment affected by the fire based on the fire data and the transmission line ledger data corresponding to the target area further includes:

[0016] If the line equation and the circular buffer zone do not intersect, then determine the positional relationship between the fire point, the straight line segment between the start and end points of the transmission line, and the conductor segment on the transmission line.

[0017] If the fire point and the conductor segment are located on the same side of the straight segment, and the distance between the fire point and the conductor segment is less than the fire point's spread radius, then the geodesic distance between the tower on the conductor segment and the fire point is calculated. If the geodesic distance between the tower on the conductor segment and the fire point is less than the fire point's spread radius, then the tower on the conductor segment is identified as a tower affected by the fire, and the transmission line, the conductor segment, and the tower affected by the fire are identified as the power grid equipment affected by the fire.

[0018] If the fire point and the conductor segment are located on different sides of the straight segment, then it is determined that the conductor segment and the towers on the conductor segment are not affected by the fire.

[0019] In an optional implementation, determining the no-burning zone corresponding to the target area based on the no-burning zone equipment corresponding to the target area includes:

[0020] For the poles in the no-burning zone equipment corresponding to the target area, calculate the geodesic circle with the pole as the center and multiple different preset buffer distances as radii, and generate the corresponding pole buffer zone based on the geodesic circle corresponding to each preset buffer distance.

[0021] For the conductor segment in the no-burning zone equipment corresponding to the target area, calculate the geodesic circle with each sampling point on the conductor segment as the center and multiple different preset buffer distances as the radius, and generate the corresponding conductor segment buffer based on all the geodesic circles corresponding to each preset buffer distance.

[0022] The union calculation of the tower buffer zone and the conductor segment buffer zone is performed to obtain the no-burning zone corresponding to the target area.

[0023] In an optional implementation, the step of overlaying the fire data, the power grid equipment affected by the fire, and the no-burning zone on the map includes:

[0024] A fire point layer is generated based on the fire data;

[0025] A layer of affected equipment is generated based on the power grid equipment affected by the fire;

[0026] A no-burning zone layer is generated based on the aforementioned no-burning zone;

[0027] The fire point layer, the affected equipment layer, and the no-burning zone layer are overlaid on the map; wherein the fire point layer and the affected equipment layer are on top of the no-burning zone layer.

[0028] In an optional implementation, the acquisition of fire data corresponding to the target area based on polar-orbiting satellites includes:

[0029] Obtain raw fire data corresponding to the target area fed back by polar-orbiting satellites;

[0030] The original fire data is preprocessed to obtain the fire data corresponding to the target area.

[0031] In an optional implementation, the preprocessing of the original fire data to obtain fire data corresponding to the target area includes:

[0032] Obtain fire data where the fire point is burning from the original fire data;

[0033] In fire data where the fire point is burning, the fire data of the same fire point are fused based on the fire point temperature, fire point region, fire point location, fire point detection time, and fire point vector range, and finally the fire data corresponding to the target area is obtained.

[0034] Secondly, the present invention provides a power grid wildfire monitoring device, the device comprising:

[0035] The data acquisition module is used to acquire fire data corresponding to the target area based on polar-orbiting satellites;

[0036] The equipment analysis module is used to determine the power grid equipment affected by the fire based on the fire data and the transmission line ledger data corresponding to the target area;

[0037] The no-burning zone determination module is used to determine the no-burning zone corresponding to the target area based on the no-burning zone equipment corresponding to the target area;

[0038] The display module is used to overlay the fire data, the power grid equipment affected by the fire, and the no-burning zone on a map.

[0039] Thirdly, the present invention provides an electronic device including a processor, a memory, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, implements the steps of the power grid wildfire monitoring method as described in any of the foregoing embodiments.

[0040] Fourthly, the present invention provides a computer-readable storage medium storing a computer program thereon, which, when executed by a processor, implements the steps of the power grid wildfire monitoring method as described in any of the foregoing embodiments.

[0041] This invention provides a method, device, electronic equipment, and storage medium for monitoring power grid wildfires. The method includes: acquiring fire data corresponding to a target area based on polar-orbiting satellites; determining the power grid equipment affected by the fire based on the fire data and transmission line ledger data corresponding to the target area; determining the prohibited burning area corresponding to the target area based on the prohibited burning area equipment corresponding to the target area; and overlaying the fire data, the affected power grid equipment, and the prohibited burning area on a map.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0051] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0052] Currently, the main methods for monitoring wildfires include satellite remote sensing monitoring, power line camera monitoring, and manual line inspection.

[0053] 1. Manual line inspection

[0054] To prevent wildfires caused by power lines and equipment, a special wildfire prevention work plan was formulated, employing a manual inspection model to focus on fire-prone areas within the power supply zone, particularly power lines and equipment in forested areas. During inspections, personnel conduct infrared thermography on connections such as switches and clamps, promptly clear flammable materials such as dead branches and weeds from power line corridors, and regularly inspect sections with potential wildfire hazards, increasing the intensity of inspections. However, inspection personnel cannot conduct a comprehensive "carpet-style" inspection of power transmission facilities traversing forests. Hazards and defects discovered during inspections cannot be immediately documented, and temporary control measures cannot be formulated for those that cannot be immediately addressed, presenting numerous difficulties in ensuring thorough hazard elimination. Furthermore, manual inspections cannot quickly detect fires, relying primarily on post-incident response.

[0055] 2. Power transmission line camera monitoring

[0056] In recent years, the increasing frequency of extreme weather events and the expansion of human activities have led to a significant increase in the risk of wildfires around power transmission lines. To ensure the stable operation of the power grid, online monitoring devices for wildfire prevention along power transmission lines, as an intelligent protection measure, have been gradually applied in the field of power facility protection.

[0057] The deployment of online monitoring devices for wildfire prevention on power transmission lines marks a shift in power grid protection from "passive response" to "proactive prevention." Its value lies not only in the direct reduction of fire losses, but also in: enhancing power grid resilience and ensuring energy supply stability under extreme weather conditions; reducing the risk of secondary equipment damage during firefighting; and providing technical support for the coordinated development of power facilities and the ecological environment.

[0058] Meanwhile, power transmission line camera monitoring also has inherent defects: firstly, the location of fire points is uncertain, and online monitoring of power transmission lines is only installed on power equipment and cannot effectively monitor all wildfires; secondly, the immaturity of the image recognition algorithm for power transmission line video monitoring makes wildfire identification difficult and inaccurate; thirdly, both online monitoring and video monitoring of power transmission lines for wildfire prevention are post-event monitoring and cannot detect or locate wildfires in a timely manner.

[0059] 3. Satellite remote sensing monitoring

[0060] Satellite remote sensing has become a core tool for monitoring forest fires, grassland fires, and industrial fires, and is widely used in emergency response and ecological research. The technical principle of satellite remote sensing for fire monitoring is mainly based on the detection of surface thermal anomalies and smoke, combined with data analysis in the multispectral, infrared, and thermal infrared bands.

[0061] Based on the above technical principles, mature fire monitoring service data has already appeared on the market. For users or scenarios with needs for large-scale coverage, uninhabited area monitoring, and real-time early warning (such as NASA FIRMS platform), fire monitoring data can be obtained directly by calling the data interface to assist users in analysis.

[0062] Satellite monitoring can not only quickly detect early forest fires, especially suitable for fire monitoring in remote and sparsely populated areas, but also continuously track the spread of major forest fires, accurately reflect the dynamic changes of the fire, and is not limited by terrain conditions; at the same time, it provides valuable meteorological and geographic information for daily forest fire prevention and aviation, helping to formulate prevention plans and implement patrol plans.

[0063] Although existing technologies have initially established a wildfire monitoring system, the following major problems still exist in practical applications:

[0064] 1. Insufficient timeliness and accuracy of satellite monitoring data: Currently, wildfire monitoring mainly relies on data from three remote sensing satellites, which are mainly based on geostationary satellite capabilities. There is still room for improvement in timeliness and accuracy, resulting in delays in the detection of fire points. Some fires have already entered a large-scale burning state by the time they are confirmed on-site. The fire covers a large area and has a long fire line, which compresses the response time of load dispatch after the fire spreads to the vicinity of the power line.

[0065] 2. Lack of an integrated "space-air-ground" assessment mechanism: Wildfire monitoring of power transmission lines and wildfire monitoring by satellite remote sensing are handled by different departments. The information is not aggregated and needs to be confirmed manually by phone or WeChat, resulting in a heavy workload for frontline personnel.

[0066] 3. No linkage between no-burning zones and fire data: Although a document on no-burning protection zones for power transmission lines has been issued, clearly defining the areas where power transmission and distribution equipment are prohibited from burning during wildfires, it has not yet been linked to wildfire alarm information. It is impossible to analyze and confirm whether the no-burning zone is involved in the first instance. On-site confirmation of the fire situation is required, especially during the planned burning period (January to February), which results in a heavy workload for frontline personnel.

[0067] 4. Low integration of wildfire monitoring and response processes: The current intelligent disaster prevention and mitigation system has initially achieved alarm data aggregation and unified work order issuance, but it currently only accesses provincial satellite remote sensing data. Data acquisition relies on web crawlers, and alarm times are generally about 30 minutes later than those on the provincial platform. Furthermore, it does not integrate power transmission line video monitoring alarm data, leaving significant room for system integration and optimization.

[0068] It is evident that while existing technologies have initially achieved intelligent monitoring capabilities for wildfires, there are still many problems such as information fragmentation, delayed response, inaccurate positioning, inefficient analysis, and insufficient visualization. There is an urgent need to comprehensively improve the level of intelligence in wildfire monitoring and the emergency response capabilities of the power grid through intelligent fusion of fire data, rapid identification of fire point impact devices, joint analysis of prohibited burning zones, and multi-dimensional visualization.

[0069] Based on this, embodiments of the present invention provide a method, device, electronic device, and storage medium for monitoring wildfires in power grids. The method includes: acquiring fire data corresponding to a target area based on polar-orbiting satellites; determining the power grid equipment affected by the fire based on the fire data and transmission line ledger data corresponding to the target area; determining the prohibited burning area corresponding to the target area based on the prohibited burning area equipment corresponding to the target area; and overlaying the fire data, the power grid equipment affected by the fire, and the prohibited burning area on a map. The present invention enables high-precision fire location based on polar-orbiting satellites, automatic identification of equipment affected by fire based on fire data and transmission line ledger data, and achieves linked analysis between the fire and the prohibited burning area by overlaying the fire data, the affected equipment, and the prohibited burning area. This facilitates rapid determination of whether a fire involves a prohibited burning area and reduces the burden of manual confirmation.

[0070] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0071] Please refer to Figure 1 This is a schematic flowchart of a power grid wildfire monitoring method provided in an embodiment of the present invention. It should be noted that the power grid wildfire monitoring method of the present invention is not based on... Figure 1The specific order described below is a limitation. It should be understood that in other embodiments, the order of some steps in the power grid wildfire monitoring method of the present invention can be interchanged according to actual needs, or some steps can be omitted or deleted. This power grid wildfire monitoring method can be applied to electronic devices such as laptops, tablets, PCs (Personal Computers), and servers. The following will describe... Figure 1 The specific process shown will be explained in detail.

[0072] Step S101: Obtain fire data corresponding to the target area based on polar-orbiting satellites.

[0073] In this embodiment, three polar-orbiting satellites with a spatial resolution of 375m can be connected to the wildfire monitoring system, achieving a positioning accuracy of 100-200m. This allows for the detection of fire activity within a 200m radius of the wildfire's latitude and longitude, with a positioning accuracy far exceeding that of geostationary satellites. This enables the earlier detection of small fires, providing frontline patrol personnel with more precise positioning and facilitating timely location of the wildfire and response.

[0074] In this embodiment, fire data may include: fire spot number, fire spot area, fire spot status (false alarm, extinguished, burning, no feedback, feedback), fire spot area, fire spot detection time, fire spot location, fire spot temperature, wetland occupancy ratio, grassland occupancy ratio, water area occupancy ratio, fire spot vector range, sensor, satellite and other parameters.

[0075] Step S102: Based on the fire data and the corresponding transmission line ledger data for the target area, determine the power grid equipment affected by the fire.

[0076] In this embodiment, the transmission line ledger data mainly includes transmission lines, conductor segments, towers, and their spatial topological relationships and attribute information, such as the name of the transmission line, the coordinates of its starting and ending points, the name of the conductor segment, and the name and coordinates of the towers on the conductor segment. By combining fire data with transmission line ledger data for equipment analysis, the power grid equipment affected by the fire in the target area can be identified, enabling rapid identification and intelligent assessment of equipment within the fire's influence range, significantly improving the response efficiency and accuracy of wildfire monitoring.

[0077] Step S103: Determine the no-burning zone corresponding to the target area based on the no-burning zone equipment corresponding to the target area.

[0078] In this embodiment, the existing no-burning protection zone documents for transmission lines can be manually matched with the transmission line data for the target area in the business platform to obtain the corresponding no-burning zone equipment data for the target area, including transmission lines, conductor segments, and towers. This data is then entered into the database, providing data support for the generation and display of no-burning zones. Based on this no-burning zone equipment, areas within a specified distance range can be generated, thus obtaining the no-burning zone corresponding to the target area.

[0079] Step S104: Overlay the fire data, the power grid equipment affected by the fire, and the no-burning zone on the map.

[0080] In this embodiment, by overlaying fire data, affected power grid equipment, and prohibited burning zones on a map, a linked analysis between the fire and the prohibited burning zones is achieved, which is beneficial for quickly determining whether a fire involves a prohibited burning zone. Furthermore, to facilitate a more intuitive assessment, the fire point, prohibited burning zone, and affected power grid equipment can be distinguished by different colors.

[0081] As can be seen, the power grid wildfire monitoring method provided by this invention can achieve high-precision positioning of the fire based on polar-orbiting satellites, and can automatically identify the equipment affected by the fire based on fire data and transmission line ledger data. By overlaying and displaying fire data, fire-affected equipment and prohibited burning areas, the linkage analysis between the fire and the prohibited burning area is realized, which is conducive to quickly determining whether the fire involves the prohibited burning area and reducing the burden of manual confirmation.

[0082] In one embodiment, step S101 may specifically include: acquiring the original fire data corresponding to the target area fed back by the polar-orbiting satellite; preprocessing the original fire data to obtain the fire data corresponding to the target area.

[0083] In this embodiment, considering that multiple polar-orbiting satellites may provide feedback on the same fire point, and that there may be invalid data in the feedback fire data, after obtaining the original fire data corresponding to the target area fed back by the polar-orbiting satellites, the original fire data is preprocessed to filter out invalid data, and the fire data of the same fire point is fused, which can improve the accuracy of fire point identification and avoid data confusion.

[0084] In one embodiment, the above-mentioned preprocessing of the original fire data to obtain the fire data corresponding to the target area specifically includes: obtaining fire data in the state of burning from the original fire data; and, in the fire data in the state of burning, fusing the fire data of the same fire point according to the fire point temperature, fire point area, fire point location, fire point detection time, and fire point vector range of each fire point, and finally obtaining the fire data corresponding to the target area.

[0085] In this embodiment, by obtaining fire data with a burning status from the original fire data, data in states such as false alarms, extinguished fires, and fires already reported can be filtered out. For fire data with a burning status, it can be determined whether the fire point temperatures of each fire point are the same or similar, whether the fire point areas are the same, whether the fire point detection times are the same, whether the fire point locations are within the current fire point vector range, and whether the distance between two fire points is getting closer as the fire spreads and the fire point area expands. For two fire points with the same or similar fire point temperatures, the same fire point areas, the same fire point detection times, fire point locations within the current fire point vector range, and increasingly closer distances, the fire data can be merged into one fire point, ultimately obtaining the fire data corresponding to the target area.

[0086] In one implementation, step S102 specifically includes: obtaining the fire location and fire spread radius corresponding to each fire point in the fire data, and constructing a circular buffer zone with the fire location as the center and the fire spread radius as the radius; constructing a line straight equation based on the starting coordinates and ending coordinates of the transmission line in the transmission line ledger data; if there is at least one intersection between the line straight equation and the circular buffer zone, then searching for candidate towers adjacent to the intersection on the transmission line; if the geodesic distance between the candidate tower and the fire point is less than the fire spread radius, then the candidate tower is determined as the tower affected by the fire, and the transmission line, the tower affected by the fire, and the conductor segment where the tower affected by the fire are located are determined as the power grid equipment affected by the fire.

[0087] In this embodiment, a circular buffer zone is constructed with the fire point location as the center and the fire point spread radius as the radius; this circular buffer zone expands as the fire point spreads, representing the range of fire point spread. For example, this circular buffer zone can be represented as... Let (h,k) represent the location of the fire point, and r represent the fire spread radius. Combining the start and end coordinates of the transmission lines from the transmission line ledger data, a straight-line equation for the line is constructed. For example, if there are n transmission lines, then the straight-line equations corresponding to each of the n transmission lines will be constructed, i.e. ;in,( , ), ( , ) respectively represent the first i The coordinates of the starting point and the ending point of the transmission line. i The value of can be 1, 2, 3, ..., n.

[0088] It should be noted that in this embodiment, the location of the fire point, the starting coordinates and the ending coordinates of the transmission line can be latitude and longitude coordinates or projected coordinates, and the unit of the fire spread radius r is meters or kilometers. Projected coordinates usually use x and y coordinates to represent the location, and the unit is usually meters or kilometers. Therefore, when constructing the circular buffer zone and the line straightness equation, if the location of the fire point, the starting coordinates and the ending coordinates of the transmission line are represented by latitude and longitude coordinates, the location of the fire point, the starting coordinates and the ending coordinates of the transmission line can be converted into projected coordinates to achieve unit uniformity.

[0089] The circular buffer zone and the line straight line equations are combined into a system of equations to calculate if there is an intersection. The output result is no intersection, one intersection, or two intersections. When there is one intersection, the nearest (closest) tower is found near the intersection. The intersection is taken as the parent node, and the nearest tower is taken as the child node. The tower corresponding to the child node is then a candidate tower. The geodesic distance between the candidate tower and the fire point is calculated. If the geodesic distance is less than the fire spread radius r, the candidate tower is identified as a tower affected by the fire. Then, using the candidate tower as the parent node, the search continues to find the nearest tower as a child node. The candidate tower corresponding to this new child node is then checked to see if the geodesic distance between it and the fire point is less than the fire spread radius r. This distance judgment process is repeated until the condition is no longer met. In this way, the information of the transmission lines, conductor segments, and towers affected by the fire can be obtained, and this information is output as the power grid equipment affected by the fire. Similarly, when there are two intersection points, neighboring towers can be found near each intersection point. Using the two intersection points as parent nodes and the adjacent towers as child nodes, the power grid equipment affected by the fire can be located by referring to the distance assessment process described above. It should be noted that, for the case of two intersection points, towers already assessed can be recorded during the search for neighboring candidate towers to avoid repeatedly assessing the distance of the same tower.

[0090] In this embodiment, geodesic distance refers to the shortest path length along the Earth's curvature between two points on the surface of an ellipsoid, rather than a straight-line distance on a plane. It takes into account the Earth's true shape (ellipsoid) and reflects the actual geographical distance between two points more accurately than planar Euclidean distance. Therefore, using geodesic distance can more accurately determine the distance between the fire point and the tower, improving the accuracy of the assessment. The geodesic distance between two points can be expressed as: ,in, This represents the Earth's radius (6371 km), )and( ( ) are the latitude and longitude coordinates of the two points respectively.

[0091] It should be noted that in practical applications, the distance between two points can be calculated using methods other than the geodesic distance method described above. For example, in a projected coordinate system, the latitude and longitude coordinates of the route can be converted to a rectangular coordinate system. and Coordinates. Point A has coordinates (x1, y1); point B has coordinates (x2, y2); the distance between points A and B is:

[0092] Rectangular coordinate calculation method: ;

[0093] Manhattan calculation method: ;

[0094] Empirical calculation method:

[0095] Same longitude: Longitude difference 1 ° ;

[0096] Same latitude: Longitude difference 1 ° ;

[0097] Equatorial reference: Longitude difference 1 ° Latitude difference 1 ° Hengwei .

[0098] In practical applications, considering that transmission lines are not straight and often have bends, it's possible that a straight section of the transmission line intersects with the fire's spread range, but the actual equipment is not within that range; conversely, it's possible that a straight section of the transmission line does not intersect with the fire's spread range, but the actual equipment is within it. Therefore, in cases where there is no intersection, the positional relationship between the fire point, the straight section of the transmission line, and the conductor segments of the transmission line can be used to further determine whether the transmission line intersects with the fire's spread range.

[0099] Based on this, step S102 above specifically includes: if the line straight equation and the circular buffer zone do not intersect, then determine the positional relationship between the fire point, the straight segment between the start and end points of the transmission line, and the conductor segment on the transmission line; if the fire point and the conductor segment are located on the same side of the straight segment, and the distance between the fire point and the conductor segment is less than the fire spread radius, then calculate the geodesic distance between the tower on the conductor segment and the fire point; if the geodesic distance between the tower on the conductor segment and the fire point is less than the fire spread radius, then determine the tower on the conductor segment as the tower affected by the fire, and determine the transmission line, the conductor segment, and the tower affected by the fire as the power grid equipment affected by the fire; if the fire point and the conductor segment are located on different sides of the straight segment, then determine that the conductor segment and the tower on the conductor segment are not affected by the fire.

[0100] In this embodiment, it is necessary to traverse every conductor segment on the transmission line and determine the positional relationship between the fire point, the straight line segment between the start and end points of the transmission line, and each conductor segment. For each conductor segment, the conductor segment equation can be established based on the tower coordinates at both ends of the conductor segment, for example... The coordinates of the fire point Substituting the equation of the conductor segment, if If so, the fire point is on the right side of the conductor segment; The fire point is on the left side of the conductor segment; If the fire point is on the conductor segment, then the fire point is on the conductor segment. Similarly, by substituting the coordinates of the towers at both ends of the conductor segment into the equation of the straight line, we can also determine whether the conductor segment is located to the left or right of the straight line segment.

[0101] When the fire point and the conductor segment are on the same side of the straight segment, there are two possibilities: either the fire point is to the left of the straight segment and the conductor segment is also to the left of the straight segment, or the fire point is to the right of the straight segment and the conductor segment is also to the right of the straight segment. In this case, calculate the distance between the fire point and the conductor segment, dis2, where dis2 = It is then determined whether dis2 is less than the fire spread radius r. If it is less than r, it is determined that the conductor segment may intersect with the fire spread range, and the geodesic distance between the tower on the conductor segment and the fire point is calculated. ,if If the value is less than r, then the tower is determined to be affected by the fire, and the tower, conductor segment, and transmission line are considered as affected power grid equipment. When the fire point and conductor segment are located on different sides of the straight segment (i.e., the fire point is on the left side of the straight segment and the conductor segment is on the right side, or the fire point is on the right side of the straight segment and the conductor segment is on the left side), since the straight segment and the circular buffer zone do not intersect, it can be determined that the conductor segment and the circular buffer zone also do not intersect, meaning that the conductor segment and the tower on the conductor segment are not affected by the fire.

[0102] It is understandable that when all conductor segments on the transmission line have been traversed and it is found that none of the conductor segments intersect with the circular buffer zone, the entire transmission line can be considered unaffected by the fire.

[0103] In one embodiment, step S103 specifically includes: for the poles in the no-burning zone equipment corresponding to the target area, calculating geodesic circles with the pole as the center and multiple different preset buffer distances as radii, and generating corresponding pole buffer zones based on the geodesic circles corresponding to each preset buffer distance; for the conductor segments in the no-burning zone equipment corresponding to the target area, calculating geodesic circles with each sampling point on the conductor segment as the center and multiple different preset buffer distances as radii, and generating corresponding conductor segment buffer zones based on all geodesic circles corresponding to each preset buffer distance; performing a union calculation on the pole buffer zones and conductor segment buffer zones to obtain the no-burning zone corresponding to the target area.

[0104] Generally speaking, a buffer zone refers to the area formed within a specified distance around a spatial feature (point, line, or polygon). For example, a buffer zone for a point feature is obtained by drawing a circle with a buffer radius R centered on the point feature; the buffer zone for a line feature is formed by drawing parallel lines on both sides of the line with R as the distance, constructing two semicircular arcs at both ends of the line, and forming the buffer zone together with the parallel lines; the buffer zone for a polygon is created by drawing parallel lines outward from the boundary of the polygon feature as the baseline, and the area within the parallel lines and the baseline is the polygon buffer zone.

[0105] In this embodiment, the geodesic distance (the true shortest distance on the geographic surface) is used to generate the buffer. Each point on the buffer boundary maintains a geodesic distance from the original feature. This ensures that the generated buffer shape is accurate on the three-dimensional Earth surface and that there is no projection distortion.

[0106] For a pole, calculate a geodesic circle centered on the pole with multiple different preset buffer distances as radii. This yields a set of all points on a spherical / ellipsoidal surface whose geodesic distance from the pole is equal to the preset buffer distance. Connecting these points gives the corresponding pole buffer zone. For example, if the preset buffer distances are 1, 3, and 5 kilometers, the resulting pole buffer zones will be calculated according to distances of 1, 3, and 5 kilometers respectively.

[0107] For a traverse segment, along multiple densely sampled points on the traverse segment, geodesic circles are calculated with each sampled point on the traverse segment as the center and multiple different preset buffer distances as radii. All geodesic circles corresponding to each preset buffer distance are then used to generate the corresponding traverse segment buffer. Taking a preset buffer distance of 1 km as an example, connecting the boundary points of the 1 km geodesic circles corresponding to all sampled points on the traverse segment generates the traverse segment buffer corresponding to a preset buffer distance of 1 km. Similarly, the traverse segment buffers corresponding to preset buffer distances of 3 km and 5 km can be obtained.

[0108] In this embodiment, after generating corresponding tower buffer zones and conductor segment buffer zones according to different preset buffer distances, spatial union calculation is performed on the tower buffer zones and conductor segment buffer zones corresponding to the same preset buffer distance. All overlapping or adjacent buffer zones are merged into a continuous polygonal region, ultimately obtaining the no-burning zone corresponding to that preset buffer distance. Taking preset buffer distances of 1, 3, and 5 kilometers as examples, 1-kilometer, 3-kilometer, and 5-kilometer no-burning zones are obtained, each representing a different fire hazard level. For example, a fire entering a 5-kilometer no-burning zone indicates a lower hazard level; a fire entering a 3-kilometer no-burning zone indicates a higher hazard level; and a fire entering a 1-kilometer no-burning zone indicates the highest hazard level. Furthermore, when visually displaying the no-burning zones, the 1-kilometer, 3-kilometer, and 5-kilometer no-burning zones can use different colors for labeling and visualization.

[0109] For example, when two or more buffers overlap, the union operation can eliminate their internal boundaries, merging the overlapping areas into a single region; when two or more buffers are adjacent (touching but not overlapping), the union operation will connect them into a larger polygonal region; for isolated regions (buffers that do not overlap or are adjacent to any other buffers), the union operation will still result in an independent region. Figure 2 The diagram shown is a schematic of a 1-kilometer no-burning zone generated with a preset buffer distance of 1 kilometer.

[0110] As can be seen, this embodiment uses the actual shortest distance on the Earth ellipsoid model to generate the buffer, overcoming the inherent distance and shape distortion problems when performing buffer analysis on a planar projected map, and providing a reliable spatial analysis basis for GIS (Geographic Information System) applications that perform global-scale, large-scale, high-latitude, or precise distance calculations.

[0111] In one embodiment, step S104 specifically includes: generating a fire point layer based on fire data; generating an affected equipment layer based on power grid equipment affected by the fire; generating a prohibited burning zone layer based on prohibited burning areas; and overlaying the fire point layer, affected equipment layer, and prohibited burning zone layer on a map; wherein the fire point layer and affected equipment layer are on top of the prohibited burning zone layer.

[0112] In this embodiment, a no-burning zone layer can be first displayed on the GIS map, and then the fire point layer and the affecting equipment layer can be overlaid on top. Furthermore, the visualization of the no-burning zone layer supports highlighting equipment within the no-burning zone and hiding other equipment; clicking on a pole or tower device provides a display of no-burning zone equipment cards and a quick device location function. It is understood that when the generated no-burning zones include 1 km, 3 km, and 5 km zones, the final display will overlay these three no-burning zone layers on the map.

[0113] In this embodiment, to avoid performance issues, the no-burn zone layer can be displayed by publishing layers, while the fire point layer and the affected device layer can be displayed by vector overlay analysis.

[0114] Among them, the vector overlay analysis involved in the fire point layer and the affected equipment layer is the process of performing logical intersection, difference, union and other topological operations on two or more vector data layers with the correct spatial coordinate system in the same area to generate a new layer with multiple attributes; the overlay process includes spatial topological operations between points and polygons, lines and polygons, and polygons and polygons to generate a new layer with multiple attributes.

[0115] Overlaying points and polygons spatially combines point features from the input layer with polygon features from the overlay layer. The output is a fusion of point data and polygon data, with the point data on top of the polygon data. For example, overlaying the fire-affected poles in the equipment layer with the no-burn zone layer can visually show whether the fire-affected poles are located in the no-burn zone.

[0116] Overlaying lines and polygons spatially combines line features from the input layer with polygon features from the overlay layer. The output is a fusion of line and polygon features, with the line feature data on top of the polygon data. For example, overlaying a fire-affected conductor segment in the equipment layer with a no-burn zone layer can visually indicate whether the fire-affected conductor segment is located within a no-burn zone.

[0117] Overlaying polygons involves combining two or more polygonal features to create a new polygon. This process can be divided into two steps: geometric intersection and attribute assignment. Geometric intersection first identifies the intersection points of all polygon boundary lines, then performs a new polygon topology calculation based on these points. Attribute assignment assigns a unique identifier to each object in the newly generated topological polygon layer and generates an attribute table that corresponds one-to-one with each new polygon object. For example, overlaying a fire point's fire spread impact area layer with a no-burn zone layer can visually demonstrate whether a fire point will affect the no-burn zone.
