DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0026] In the description of the embodiments of the present application, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or the orientation or position relationship in which the invented product is usually placed when used. It is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0027] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0028] In the description of the embodiments of the present application, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] In recent years, with the development of satellite remote sensing technology, many commercial satellite companies have emerged in the market, and many small satellites, sub-meter satellites and other resources have also entered the market, providing solid data support for applications in various industries. In the power sector, many units within the system and commercial companies outside the system have carried out inspections of transmission channel hazards based on satellite remote sensing, providing technical support for identifying environmental hazards in transmission channels.

[0030] However, the existing hidden danger association methods mainly use existing commercial software such as ArcGIS, and are manually implemented through manual marking methods. The workload is large, time-consuming and labor-intensive, and it is easily interfered by human subjective factors, resulting in certain errors in the associated attribute fields. For example, the Chinese invention patent application with publication number CN110245163A proposes a method for troubleshooting hidden dangers in power system operation, including data acquisition, data preprocessing, hidden danger data storage and calculation, data analysis and mining, and visualization of hidden danger analysis results. The method adopts: (1) by classifying and counting hidden danger information, multi-dimensionally displaying the association between hidden dangers and information such as equipment, seasons, and different equipment commissioning years, building an information visualization platform to facilitate intuitive monitoring and management of equipment; (2) intuitively displaying the association between hidden dangers and seasons, environments, etc., sorting out historical information, guiding inspection personnel to inspect key information that needs to be inspected in different seasons and environments, and improving inspection efficiency; (3) through accident case analysis, displaying common accident data, possible consequences, etc., so as to find rules and guide hidden danger inspection and management work.

[0031] However, this method is a method of statistically analyzing, correlating and analyzing all historical hidden danger information that occurred in the power equipment and facilities, which is obviously different from the research object of this application. Moreover, the technical solution in the above patent application mainly uses Mahout's correlation analysis algorithm to analyze the correlation between the hidden danger category and various parameters, and finds the correlation between various hidden dangers and various parameters, which does not fall into the category of spatiotemporal correlation.

[0032] At present, the use of satellite remote sensing data to carry out environmental hazard inspections of transmission channels has become an important part of power inspections. The satellite inspection of power grids mainly includes two important links: one is the intelligent identification and positioning of environmental hazards on satellite remote sensing images, and the other is to associate the identified environmental hazards with power equipment and facilities. There are many studies on intelligent identification technology of hidden dangers, but there are few studies on the methods of associating hidden dangers with power equipment and facilities, and the definition of associated fields is not scientific and reasonable enough. At present, manual association is still used to fill in the associated attributes of each hidden danger one by one, which results in low inspection efficiency, low automation level, and large human errors. Moreover, the degree of association between the two is not close, and the setting of the associated attribute fields is unreasonable, which has little guiding significance for the targeted verification of front-line personnel.

[0033] Based on the above situation, the present application proposes a method for associating satellite inspection results of environmental hazards in power transmission channels and a related device. The present application is described in detail below in conjunction with embodiments and drawings.

[0034] like Figure 1 As shown, it is a first flow chart of the method for associating satellite inspection results of power transmission channel environmental hazards of the present application, which may include: S101, obtaining spatial geographic data of tower points and transmission lines based on satellite patrol results.

[0035] This application extracts specific geographic location information about poles and transmission lines from satellite patrol images or data. In practical applications, satellite patrol results usually come from high-resolution satellite images, remote sensing data, or dedicated power inspection satellites. These data may contain visible light images, infrared images, or multispectral images to capture surface features and details of power facilities. Image processing technology and geographic information system (GIS) tools can be used to automatically identify and extract the locations of poles and transmission lines from satellite images. The extracted data is usually expressed in the form of geographic coordinates (such as longitude and latitude) and may contain altitude information (for three-dimensional data). These data can be stored in a GIS database for subsequent analysis and processing.

[0036] S102, defining the association field between the environmental hazards of the power transmission channel and the power grid information.

[0037] In order to associate satellite patrol results with environmental hazards in transmission channels, a series of association fields need to be defined, which will serve as a bridge between the two. In practical applications, the selection of association fields can accurately reflect the relationship between environmental hazards in transmission channels and power grid information. For example, fields may include tower number, line name, hazard type, hazard level, discovery time, etc. In addition to defining fields, association rules can also be formulated to clarify which fields are associated with each other. For example, a specific tower number may be associated with multiple transmission lines, and a transmission line may contain multiple hazard points.

[0038] S103, determining the filling content of each associated field according to the spatial geographic data of the tower points and the transmission lines.

[0039] After defining the associated fields, you can fill these fields based on the actual tower point and transmission line data. Specifically, you can first match the tower point and transmission line data in the satellite patrol results with the records in the power grid information database. Once the match is successful, you can fill in the associated fields based on the matching results. For example, for a specific tower point, fill in the corresponding line name, hidden danger type, hidden danger level and other information.

[0040] S104, according to the filled content, the environmental hazards of the power transmission channel and the satellite inspection results are associated.

[0041] Finally, the filled-in associated fields are used for actual analysis and application, closely linking the environmental hazards of the transmission channel with the satellite inspection results. In actual applications, in order to more intuitively display the associated results, GIS tools or data visualization software can be used to present information such as the location of potential hazards, transmission lines, and towers in the form of a map, which helps operation and maintenance personnel quickly understand the status of the power grid and make more accurate decisions.

[0042] The method for associating the results of satellite inspections of environmental hazards in power transmission channels proposed in this application can significantly shorten the operation time of satellite inspections of hidden dangers in power transmission channels and improve the level of automation.

[0043] like Figure 2 As shown, it is a second flow chart of the method for associating satellite inspection results of power transmission channel environmental hazards of the present application, which may include: S201, obtain the power grid GIS data and the transmission channel environmental hazard inspection vector map layer based on satellite remote sensing.

[0044] The data that needs to be obtained include power grid GIS (Geographic Information System) data and transmission channel environmental hazard inspection vector map layer based on satellite remote sensing.

[0045] Among them, the power grid GIS data refers to a data set that uses geographic information system (GIS) technology to digitally manage and display information such as the spatial location, attributes, and operating status of power grid facilities. The power grid GIS data may include: spatial location information of power grid facilities, such as the geographical location coordinates of transmission lines, substations, and distribution equipment; attribute information of power grid facilities, such as the name, type, specification, and manufacturer of the facilities; and operating status information of power grid facilities, such as real-time operating data such as voltage, current, power, and load. In this embodiment, the power grid GIS data includes a tower point vector layer and a transmission line line vector layer. The tower point vector layer is a data layer used in the power grid GIS to represent the location of the tower, and records the precise location of each tower on the map in the form of points. The line vector layer of the transmission line is a data layer used in the power grid GIS to represent the direction of the transmission line, and records the path of the transmission line on the map in the form of lines. Through the line vector layer of the transmission line, the direction and layout of the transmission line can be clearly understood, which is convenient for line planning, operation and maintenance monitoring, and other tasks.

[0046] The transmission channel environmental hazard patrol vector layer based on satellite remote sensing uses satellite remote sensing technology to obtain environmental information of the transmission channel area and converts it into a vector layer for identifying and monitoring environmental hazards in the transmission channel. In practical applications, these hazards may include geological disaster hazards, vegetation growth hazards, and human activity hazards. In this embodiment, the transmission channel environmental hazard patrol vector layer based on satellite remote sensing is a surface layer. In GIS, the surface layer is used to represent geographical phenomena or features with two-dimensional spatial extension. For the transmission channel environmental hazard patrol vector layer, the surface layer is used to represent environmental hazard areas that may exist in the transmission channel, such as areas prone to geological disasters, areas with dense vegetation, areas with frequent human activities, etc. These areas may pose a threat to the safety of the transmission channel and therefore require special attention and monitoring.

[0047] It should be noted that the surface layer is composed of a series of polygons, each of which represents an environmental hazard area. Each polygon contains geographic location coordinates and related attribute information, such as hazard type, severity, impact range, etc.

[0048] In order to achieve automatic association, the association fields are defined as follows: Table 1 Related field definitions

[0049] The associated fields in Table 1 are introduced in detail: (1) JD: the longitude of the geometric center point of the hidden danger.

[0050] (2) WD: the latitude of the geometric center point of the hidden danger.

[0051] (3) ZJXLMC: refers to the name of the line closest to the geometric center point of the hidden danger map. This field binds the hidden danger map to the line. It helps to determine the specific location and impact range of the hidden danger.

[0052] (4) ZJGTBH: refers to the tower number from the geometric center point of the hidden danger map to the nearest tower. This field binds the hidden danger map to the specific tower point on the line, which facilitates subsequent maintenance and management work.

[0053] (5) ZJXLJL: refers to the shortest distance to the nearest line. If the intersection of the vertical line from the geometric center of the spot to the line falls on the line, the shortest distance is the vertical distance; if the intersection of the vertical line from the geometric center of the spot to the line falls on the extension line of the line, the distance from the geometric center of the spot to the nearest tower is taken as the line distance.

[0054] (6) ZJGTJL: refers to the straight-line distance from the geometric center of the hidden danger pattern to the nearest tower. This distance helps to assess the direct impact of the hidden danger on the tower.

[0055] (7) DXHC: With the nearest tower as the center, if the hidden danger spot is between the nearest tower and the next large tower, it belongs to the small side; if the hidden danger spot is between the nearest tower and the previous small tower, it belongs to the large side. This field helps to determine the relative position of the hidden danger, which is of great significance for line maintenance and emergency repair work.

[0056] It should be noted that the above-mentioned associated field definition is only an example. In other embodiments of the present application, the above-mentioned associated field definition may be added or deleted according to usage requirements, and may also be adaptively adjusted.

[0057] S202, calculating the geometric center point of the hidden danger map.

[0058] The transmission channel environmental hazard inspection vector layer based on satellite remote sensing includes multiple hazard spots. The hazard spots are areas with potential safety hazards that are marked in the transmission channel environmental hazard inspection vector layer after the satellite remote sensing images are processed and analyzed. These spots are usually generated based on the feature extraction and classification algorithms of satellite remote sensing images, and can intuitively display the distribution of environmental hazards in the transmission channel.

[0059] Calculate the geometric center point of each hidden danger spot O , using the geometric center point O The longitude and latitude ( x , y ) as the location attribute field of the hidden danger map, x The value is the JD attribute value, y The value is used as the WD attribute value.

[0060] This can be achieved by: Use GIS software or programming library to load the vector layer containing the hidden danger spots, and ensure that the spots in the vector layer have the correct geometry and coordinate reference system. For each hidden danger spot, you can use the geometric calculation function provided by the GIS software or programming library to calculate its geometric center point. In GIS software, you can usually get the longitude and latitude calculation results directly from the calculation results. If you use a programming library, the geometric center point object has .x and .y attributes, representing longitude and latitude, respectively. Then, add two new fields JD (longitude) and WD (latitude) to the attribute table of the vector layer. In GIS software, this can usually be achieved through "add field" or similar functions. In programming, you can use the .assign() method of Geopandas or create a new column directly in the attribute data frame. Finally, fill the longitude and latitude values ​​of the geometric center point of each hidden danger spot into the JD and WD fields respectively. Save the updated vector layer to a file or database for subsequent use.

[0061] S203, associate with the nearest tower.

[0062] Calculate the geometric center point of each hidden danger spot separately O The distances from n towers are recorded as , and sort the obtained n distances to get the minimum distance , as "ZJGTJL", then "ZJGTBH" fills in the corresponding tower number, assuming , (where m≤n).

[0063] This can be achieved through the following methods: Make the location data of each tower represented in the form of a point. Each point has longitude and latitude coordinates. After obtaining the geometric center point O of each hidden danger spot, calculate the distance between the geometric center point O of each hidden danger spot and all towers. The distance calculation can use Euclidean distance, Haversine formula or other appropriate distance measurement methods. Then find the minimum distance and the corresponding tower number. In the vector layer attribute table of the hidden danger spot, add two new fields: "ZJGTJL" and "ZJGTBH". The minimum distance Fill in the "ZJGTJL" field and number the corresponding tower. Fill in the "ZJGTBH" field. Then save the updated vector layer to a file or database for subsequent use.

[0064] S204, associate the nearest line.

[0065] T m The line name is used as the "ZJXLMC" attribute value.

[0066] From the geometric center O Departure, to and Draw perpendicular lines, and the perpendicular line segments are and , the vertical feet are and ,judge and Which is on the line. On the line, "ZJXLJL" is , otherwise "ZJXLJL" is .

[0067] S205, filling in the attribute fields on the size side.

[0068] For each hidden danger spot, a local coordinate system is established. The local coordinate system takes the tower position of "ZJGTBH" as the center of the circle, and the direction of increasing tower number as the positive direction of the x-axis. OIf the point falls in quadrants 1 and 4 of the local coordinate system, the "DXHC" attribute field is filled with "Large Side"; if O If the point falls in quadrants 2 or 3 of the local coordinate system, the "DXHC" attribute field is filled with "Small Side".

Figure 3 middle, to The geometric center point O The distance between the four towers is the shortest distance for tower #002. The corresponding tower.
