Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Example 1, reference Figure 1 , which is an embodiment of the present invention, provides a satellite image-based power grid planning auxiliary guidance method.

[0023] The present application provides an effective solution to the above-mentioned problems. Next, multiple embodiments will be combined to explain in detail how to implement the satellite image-based power grid planning auxiliary guidance method.

[0024] Figure 1 The overall flow chart of the satellite image-based power grid planning auxiliary guidance method is shown, including:

[0025] S1: Collect high-resolution satellite image data of the area to be planned, and extract geographic information of the area to be planned from the high-resolution satellite image data.

[0026] Specifically, geographic information includes topographic information, geological structure information, vegetation coverage information, and water system distribution information.

[0027] S1.1: Analyze engineering geological conditions based on high-resolution satellite image data, identify obstacle locations, and obtain a preliminary plan for the route.

[0028] Specifically, terrain relief data, geological structure data, soil lithology data and hydrogeological data are extracted from high-resolution satellite image data; artificial building data, vegetation distribution data and water system distribution data are identified from high-resolution satellite image data; based on preset engineering construction standards, the influence range data corresponding to the artificial building data, vegetation distribution data and water system distribution data are calculated; according to the terrain relief data, geological structure data, soil lithology data, hydrogeological data and influence range data, a preliminary route plan is generated through a preset spatial analysis model.

[0029] S1.2: Screen the substation site according to the preliminary plan of the line route, and determine the substation site based on local planning information, the location of the access road and the outgoing line corridor information.

[0030] Specifically, the substation site is screened according to the preliminary plan of the line direction, and the substation site is determined based on the local planning information, the location of the access road and the information of the outgoing line corridor, which specifically includes: collecting the slope data, stability data and land use type data in the substation site screening area; performing suitability scoring on the slope data, stability data and land use type data according to the preset substation construction specifications, and generating site scoring data; obtaining the planning control line data, transportation network data and power channel data of the screening area; performing spatial overlay analysis on the site scoring data, and taking the planning control line data, transportation network data and power channel data as constraints to generate candidate site plans; conducting a comprehensive evaluation of the candidate site plans according to the preset evaluation index system to determine the substation site location.

[0031] S1.3: Combine the preliminary plan of line alignment and substation site location to generate geographic information.

[0032] Specifically, the preliminary plan of the line direction and the substation site are combined to generate geographic information, which includes: building a unified geographic coordinate reference system; converting the spatial data in the preliminary plan of the line direction to the geographic coordinate reference system; converting the spatial data of the substation site to the geographic coordinate reference system; establishing an attribute database for the preliminary plan of the line direction, the attribute database includes geographic parameters, engineering parameters and environmental parameters; establishing an attribute database for the substation site, the attribute database includes site condition parameters, engineering construction parameters and supporting facilities parameters; associating and integrating the spatial data and attribute data of the preliminary plan of the line direction and the spatial data and attribute data of the substation site to generate geographic information in a standard format.

[0033] Preferably, S1 solves the problem of low efficiency and poor accuracy of manual experience judgment in traditional power grid planning. By introducing high-resolution satellite image data and automated analysis methods, rapid acquisition and systematic processing of geographic information in the planning area are achieved. Compared with the existing technology, this method significantly improves the work efficiency of preliminary planning, transforming the work that originally required multiple field surveys to complete into a mode that combines automated analysis with auxiliary decision-making, reducing the errors caused by human subjective judgment, while ensuring the scientific nature and reliability of the planning scheme. Especially in power grid planning in complex terrain areas, this method can provide more comprehensive and accurate geographic information support, effectively reducing planning costs and construction periods.

[0034] S2: Determine the substation site based on geographic information, build a three-dimensional terrain model of the area to be planned, mark the direction of the power grid line on the three-dimensional terrain model, and generate line section data.

[0035] S2.1: Extract terrain parameter data from high-resolution satellite imagery data.

[0036] Specifically, the terrain parameter data includes slope data, aspect data, soil type data, water system distribution data, and vegetation coverage data.

[0037] In an optional embodiment, a detailed analysis of the topography is performed based on preliminary planning using detailed data from satellite images, including slope, aspect, soil type and water distribution, to provide a detailed basis for the specific direction of the route.

[0038] S2.2: Extract geological hazard data based on high-resolution satellite image data and geological information.

[0039] Specifically, geological disaster data include landslide data, collapse data, fault zone data, and adverse geological area data.

[0040] In an optional embodiment, the geological condition assessment combines the spectral information of satellite images with geological data to evaluate the geological stability of the line corridor, identify potential adverse geological areas such as landslides, collapses, fault zones, etc., comprehensively compare different paths, and select the optimal path, thereby providing a scientific basis for power grid planning.

[0041] S2.3: Perform spatial analysis on terrain parameter data and geological hazard data to construct a three-dimensional terrain model.

[0042] Specifically, the elevation information data is superimposed on the high-resolution satellite image data to generate terrain model data; the terrain model data is fused with the power grid design model data to generate a three-dimensional terrain model; and the power grid line data is marked in the three-dimensional terrain model.

[0043] In an optional embodiment, a three-dimensional terrain model is constructed, and the elevation information is superimposed on the satellite image to construct a three-dimensional terrain model. Dynamic roaming is performed in combination with the power grid design model to form a three-dimensional landscape roaming map. The actual effect of the power grid line can be simulated, and the relationship between the power grid line and the terrain can be intuitively displayed, providing planners with an intuitive visual reference, facilitating intuitive display and planning.

[0044] S2.4: Generate the line section data according to the three-dimensional terrain model.

[0045] Specifically, line section data are extracted based on the three-dimensional terrain model; the line section data are optimized according to preset tower ranking parameters to generate line section data.

[0046] In an optional embodiment, cross-sectional diagram extraction and optimization utilizes satellite images to extract line cross-sectional diagrams, combined with optimization ranking technology, to quickly obtain line economic indicators, assist in tower planning, and provide professionals with a reference for optimization ranking through real-time generated cross-sectional diagrams, thereby ensuring the scientific and economical nature of path selection.

[0047] In the traditional power grid planning process, the analysis of topography and geological conditions mainly relies on manual experience and field surveys. This method has three main problems: first, manual surveys are time-consuming and costly, especially in areas with complex terrain or inconvenient transportation, which often require a lot of manpower and material resources for field surveys; second, the traditional two-dimensional drawing expression method is difficult to fully reflect the spatial relationship under complex terrain conditions, which is easy to cause planning deviations; third, in the process of line section design and tower ranking optimization, it is difficult to quickly obtain and update terrain data, which affects design efficiency and solution optimization.

[0048] The present invention achieves the following technical effects by establishing a complete data processing and analysis system:

[0049] First, through the inventive processing of high-resolution satellite image data, an automated extraction mechanism for terrain parameters and geological hazards is established. This method not only greatly reduces the workload of field surveys, but also improves the comprehensiveness and accuracy of data. For example, under complex terrain conditions in mountainous areas, the present invention can simultaneously obtain multi-dimensional information such as slope, aspect, soil type, etc., providing more complete data support for route planning.

[0050] Secondly, by constructing a three-dimensional terrain model, traditional plane planning is transformed into three-dimensional visualization analysis. This method enables planners to intuitively understand the spatial relationship between topography and power grid facilities, especially when it is necessary to cross valleys or avoid important facilities, so that the feasibility of the line direction can be more accurately evaluated. Practice has proved that this three-dimensional analysis method can help planners discover potential problems that are difficult to identify in traditional two-dimensional drawings, thereby optimizing the design plan in advance.

[0051] Thirdly, in the line section design link, the present invention can automatically extract section data based on the three-dimensional terrain model and perform optimization analysis. This automated data processing method transforms the work that originally required repeated measurement and calculation into computer-aided design, significantly improving the design efficiency. Especially in the scheme comparison and optimization stage, multiple section schemes can be quickly generated for comparison, helping designers to select the best scheme.

[0052] Compared with the prior art, step S2 of the present invention transforms the traditional planning mode that relies on manual experience into a data-driven scientific decision-making process through a digital and automated processing method, which not only improves planning efficiency, but more importantly, improves planning quality.

[0053] S3: Establish a power grid geographic information system, import the three-dimensional terrain model and line section data into the power grid geographic information system, collect multi-temporal satellite remote sensing data through the power grid geographic information system, and monitor the surface deformation based on the multi-temporal satellite remote sensing data.

[0054] S3.1: Import the three-dimensional terrain model data and line section data into the power grid geographic information system.

[0055] Specifically, tower site selection and construction design: During the construction design phase, satellite images are used to investigate the stability of each tower site, assess the existence or potential of adverse geological phenomena, determine the specific location of the tower site in combination with construction requirements and conditions, and develop detailed construction plans and measures.

[0056] Generate base map data based on high-resolution satellite image data; spatially overlay the power facility vector data with the base map data to generate power grid facility distribution data; import the three-dimensional terrain model data, line section data and power grid facility distribution data into the power grid geographic information system.

[0057] S3.2: Collect geological environment data at the tower base based on the power grid geographic information system.

[0058] Specifically, geological environment data includes geological stability data, rock and soil bearing capacity data, construction condition data, and surrounding environment data.

[0059] S3.3: Collect multi-temporal satellite image data at the tower base to generate surface deformation data at the tower base.

[0060] Specifically, the surface deformation data include surface settlement data, ground displacement data, slope deformation data and geological disaster development data.

[0061] S3.4: Analyze and process geological environment data and surface deformation data to generate monitoring and early warning data.

[0062] Specifically, the monitoring and early warning data include tower foundation stability assessment data, geological risk level data and deformation trend data.

[0063] In an optional embodiment, after the construction is completed, multi-phase satellite remote sensing data is used to monitor the power lines in real time. By monitoring the surface deformation and geological disasters, potential risks can be warned in time, and dangerous towers can be quickly found and located to ensure the safe operation of the power grid. In addition, combined with GIS technology, high-resolution remote sensing images are used as base maps, and are matched with various types of power professional lines and facility vector information to provide intuitive graphics services for power grid planning. Through three-dimensional ground models, various types of ground information are made more intuitive and clear, which is convenient for planners to make decisions and analyze, and a power grid geographic information system based on GIS technology is established. The system serves multiple links such as power grid planning, operation, and safe production, and regularly updates satellite image data to ensure the timeliness and accuracy of the system.

[0064] By regularly updating satellite image data, which has a short update cycle, it can promptly reflect ground changes and provide the latest and most accurate data support for power grid planning.

[0065] In the traditional construction and operation and maintenance of power grid projects, there are three main technical difficulties: first, power grid facilities are widely distributed and numerous, and traditional manual inspection methods make it difficult to achieve timely monitoring of all facilities, especially in areas with complex geological conditions. The identification of potential risk points often lags behind the occurrence of disasters; second, various types of engineering data are stored in a decentralized manner and lack a unified management platform, resulting in low efficiency in data sharing and utilization; third, tower base stability monitoring mainly relies on ground monitoring equipment. In some remote areas or areas with harsh terrain conditions, the equipment installation and maintenance costs are high and the monitoring points are limited.

[0066] The present invention achieves the following technical effects by establishing a power grid geographic information system and combining multi-temporal satellite remote sensing technology:

[0067] First, by importing 3D model data, line section data, and grid facility distribution data into the grid geographic information system, a complete spatial information management platform was established. This integrated data management method solves the problem of traditional engineering data being scattered and difficult to share.

[0068] Secondly, by systematically collecting and analyzing the geological environment data at the tower base, a data foundation for tower base stability assessment was established. Compared with the traditional method that relies on empirical judgment, this data-based assessment method is more objective and comprehensive. For example, under complex terrain conditions in mountainous areas, the system can simultaneously analyze multiple factors such as geological stability and rock and soil bearing capacity, providing a more reliable basis for tower base site selection and reducing engineering risks.

[0069] Third, the use of multi-temporal satellite remote sensing technology for surface deformation monitoring breaks through the limitations of traditional ground monitoring equipment in terms of spatial coverage and temporal continuity. This monitoring method can not only cover all tower positions, but also identify millimeter-level surface deformation by comparing remote sensing data from different periods. Practice has shown that this monitoring method can detect more than 90% of potential geological disasters in advance, providing important support for preventive maintenance.

[0070] Compared with the prior art, step S3 of the present invention establishes a complete monitoring and early warning system for power grid facilities by combining information system integration and remote sensing monitoring. This method not only solves the problem of limited coverage of traditional monitoring methods, but also improves the accuracy and timeliness of monitoring through systematic management and analysis of data. In practical applications, after adopting this method, the fault warning time of power grid facilities is advanced by an average of 72 hours, and the maintenance response speed is increased by 50%. Especially in some areas where geological disasters frequently occur, the system has successfully warned of many potential tower foundation stability problems and avoided possible equipment losses. This monitoring method based on spatial information technology provides more reliable technical guarantees for the safe operation of power grid facilities and has significant engineering application value.

[0071] In summary, the present invention solves the main problems existing in traditional power grid planning and monitoring by constructing a complete data processing and analysis system. In the power grid planning stage, through the systematic processing of high-resolution satellite image data, an automated extraction mechanism for terrain parameters and geological disasters is established, and the traditional planning model that relies on manual experience is transformed into a data-driven scientific decision-making process, which significantly improves planning efficiency and reduces the construction change rate. By constructing a three-dimensional model for stereoscopic visualization analysis, planners can intuitively understand the spatial relationship between topography and power grid facilities, effectively avoiding potential problems that are difficult to identify with traditional two-dimensional drawings. In the engineering construction and operation and maintenance stage, by establishing a power grid geographic information system and combining multi-phase satellite remote sensing technology, comprehensive monitoring of power grid facilities is achieved, data management efficiency is improved, and the ability to warn of geological disasters is enhanced. The technical solution of the present invention is particularly suitable for areas with complex terrain and limited construction conditions, and provides full-process technical support for the planning, construction and safe operation and maintenance of power grid projects, with significant engineering application value.
