Description

Technical Field

[0001] This invention relates to the field of map display technology, and specifically to a method and system for generating geographic wiring diagrams of power facilities based on GIS positioning. Background Technology

[0002] Since a large number of production and living facilities rely on electricity for operation, whether it is a fire caused by a short circuit, an electric shock accident caused by leakage, or a regional power outage caused by facility failure, all of these can cause significant economic losses. Therefore, the safety and reliability of power generation, transmission, and distribution facilities are of utmost importance.

[0003] To maintain the stable operation of power facilities, relevant personnel are usually arranged to conduct regular inspections of power poles. However, manual inspection is very inconvenient and prone to safety issues. Existing technologies propose using drones for power pole inspection. However, the pole locations obtained through drone positioning are point data. When mapping these locations onto a GIS map, it is necessary to determine the direction of several points and connect them, which is a rather cumbersome process. The present invention addresses the problem of how to quickly analyze and process the information collected by drones and provide intuitive feedback to the backend processing unit for maintenance. Summary of the Invention

[0004] The purpose of this invention is to provide a method and system for generating geographic wiring diagrams of power facilities based on GIS positioning. While using drones to inspect power poles, the drones provide feedback on the latitude and longitude coordinates of the poles. Based on this, a design is proposed to pre-position the poles on the GIS map according to the associated latitude and longitude coordinates and inspection results, eliminating the need for further judgment on the connection of the poles on the GIS map, thus improving the generation efficiency of geographic wiring diagrams of power facilities.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0006] A method for generating geographic wiring diagrams of power facilities based on GIS positioning, comprising:

[0007] S1. Obtain pole information collected by the drone during line inspection, and associate the corresponding pole information according to the hierarchical order of the poles in the line to build a pole identity information database.

[0008] S2. Based on the relationship between pole information in the pole identity information database, modify the latitude and longitude coordinates corresponding to the pole in the pole information to latitude and longitude line segments, and update the pole identity information database;

[0009] S3. Map the latitude and longitude lines corresponding to the pole number in the updated pole identity information database onto the GIS map. Connect several latitude and longitude lines on the GIS map to form a line, thereby forming a power facility geographic wiring diagram. Display the pole information on the power facility geographic wiring diagram using preset markers.

[0010] A further preferred technical solution is that when the drone is inspecting the line, it takes pictures of the towers in the order of their hierarchical structure, collects information from the pictures, and analyzes the information to obtain tower information.

[0011] The process of constructing the pole and tower identity information database is as follows: the table is defined in advance, and the corresponding pole and tower information is stored in each row in the order of the upper and lower levels of the poles and towers in the line. The pole and tower name in the information is used as the column header of each column in each row, and the latitude and longitude coordinates in the information of the pole and tower are stored in other columns.

[0012] A further preferred technical solution is that the pole information includes pole name, latitude and longitude coordinates, photo taking time, voltage level, line name, turning angle, altitude, pole type, span, total number of defects, tree obstructions, defect information, guy wire insulation, ancillary facilities, number of guy wires, license plate status, conductor type, number of circuits, conductor joints, pole material, crossing area, guy wire model, insulator type, geographical environment, three-wire connection, high and low voltage on the same pole, and conductor model. The latitude and longitude coordinates are composed of longitude and latitude.

[0013] A further preferred technical solution is that the process of associating the corresponding tower information according to the hierarchical order of the towers in the line is as follows: add a column to the table, which is defined as the name of the superior tower. Find the name of the superior tower corresponding to the tower name in each row according to the hierarchical order of the towers in the line, and fill it into the column.

[0014] A further preferred technical solution is that the process of updating the pole identification information database is as follows:

[0015] In each row of the pole identity information database, find the name and latitude / longitude coordinates of the superior pole and use the latitude / longitude coordinates as the starting coordinates; locate the row containing the superior pole based on its name and extract the corresponding latitude / longitude coordinates, using the latitude / longitude coordinates as the ending coordinates.

[0016] Modify the definition of latitude and longitude coordinates in each row of the table to the starting coordinates; and add a column to the table, which is defined as the ending coordinates. Then connect the starting and ending coordinates in each row to form a latitude and longitude line segment to update the tower identity information database.

[0017] A further preferred technical solution is that, where the pole information includes at least one auxiliary facility, the process of displaying the pole information on the power facility geographic wiring diagram through preset markers is as follows: different graphic markers are set in advance for different auxiliary facilities, and then the latitude and longitude coordinates of the pole where the auxiliary facility is located are used as the center point of the graphic marker, and the graphic marker is mapped onto the corresponding pole through the latitude and longitude coordinates.

[0018] A further preferred technical solution is that the process of collecting and analyzing information from captured images to obtain tower information is as follows: information is collected and analyzed from captured images using manual methods or AI models to obtain tower information.

[0019] A GIS-based power facility geographic wiring diagram generation system, employing the aforementioned GIS-based power facility geographic wiring diagram generation method, includes:

[0020] Pole and Tower Identity Information Database Construction Module: Obtain pole and tower information collected by drones during line inspections, and associate the corresponding pole and tower information according to the hierarchical order of the poles and towers in the line to construct a pole and tower identity information database;

[0021] Pole Identity Information Database Update Module: Based on the relationships between pole information in the pole identity information database, the module modifies the latitude and longitude coordinates corresponding to the pole information into latitude and longitude line segments, and updates the pole identity information database.

[0022] The power facility geographic wiring diagram generation module maps the latitude and longitude lines corresponding to the pole numbers in the updated pole identity information database onto the GIS map. Several latitude and longitude lines are connected on the GIS map to form lines, thereby forming a power facility geographic wiring diagram. The pole information is then displayed on the power facility geographic wiring diagram using preset markers.

[0023] The beneficial effects of this invention are:

[0024] This invention provides a method and system for generating geographic wiring diagrams of power facilities based on GIS positioning. It proposes that while using drones to inspect power poles, the drones' own positioning devices can provide feedback on the latitude and longitude coordinates of the poles. Since these coordinates are initially undirected, this invention proposes a preprocessing design. This preprocessing design modifies the latitude and longitude coordinates of the poles before mapping them onto the GIS map, based on the associated coordinates and inspection results. The modified coordinates are replaced with latitude and longitude line segments, each composed of the coordinates of the upper and lower level poles. This establishes a "pole-latitude and longitude line segment" relationship. When mapping these line segments onto the GIS map according to this relationship, several line segments can be directly connected on the GIS map to form a line. The GIS map generation software does not need to further determine the connections between the latitude and longitude coordinates, thus improving the efficiency of generating geographic wiring diagrams of power facilities.

[0033] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0034] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0036] Example 1

[0037] In this embodiment, to maintain the stable operation of power facilities, and considering that manual inspection is very inconvenient when inspecting high-level nodes of towers, a method of using drones to inspect towers is proposed. Although there are existing technical solutions for using drones to inspect towers, this application aims to process and visualize the data collected by drone inspections, so that the back-end processing terminal can take maintenance measures for power facilities through visualized drone inspection results to maintain the stable operation of power facilities.

[0038] When using drones to inspect power poles, the backend processing unit receives images taken by the drones, along with the corresponding time and location information. The images can be tagged using the time and location information. Simultaneously, by analyzing the images, information about the status of the power poles can be collected. The backend processing unit obtains the current power pole information and uses this information to maintain the power facilities.

[0039] Based on this, in existing technologies, since drones have their own positioning devices, namely GPS positioning, when uploading images to the backend processing terminal, the drone also uploads the location of the drone when the image was taken. This location information is the longitude x and latitude y obtained through GPS, that is, the longitude and latitude point (x, y).

[0040] When using drones to inspect power poles, the pole's location is typically determined using latitude and longitude points (x, y). Once the pole's location is determined, it can be imported into a GIS map, i.e., marked as a point on the GIS map. Figure 1As shown, after substituting the pole locations into the GIS map, only the pole's own location can be obtained, such as (xa, ya), (xc, yc), (xz, yz), (xq, yq), and (xd, yd). Since the latitude and longitude points (x, y) are point data, they cannot reflect direction. Therefore, routes cannot be directly formed on the GIS map. Staff need to manually import routes or connect them to display the drone inspection routes on the GIS map, which is a rather cumbersome operation.

[0041] To address the aforementioned issues, this invention proposes a method for generating geographic wiring diagrams of power facilities based on GIS positioning. Specifically, it proposes a preprocessing design scheme for latitude and longitude coordinates. This preprocessing involves modifying the latitude and longitude coordinates into latitude and longitude line segments based on associated latitude and longitude coordinates and inspection results before mapping the tower information onto the GIS map. These line segments are composed of the latitude and longitude coordinates of upper and lower level towers, establishing a "tower-latitude and longitude line segment" association. This allows the invention to map the latitude and longitude line segments onto the GIS map according to this association. Figure 2 As shown, a line can be directly connected on a GIS map by several latitude and longitude lines, and staff do not need to make further judgments on the connection between latitude and longitude coordinates, which can improve the generation efficiency of the geographical wiring diagram of power facilities.

[0042] Furthermore, this invention uses the GPS positioning uploaded when the drone takes pictures as the location of the pole. In actual operation, in order to collect accurate location information, the drone can be operated to hover directly above the pole, and the GPS positioning uploaded by the drone when it takes pictures directly above the pole can be used as the latitude and longitude of the pole.

[0043] Specifically, such as Figure 3 As shown, the method for generating a geographical wiring diagram of power facilities includes the following steps:

[0044] S1. Obtain pole information collected by the drone during line inspection, and associate the corresponding pole information according to the hierarchical order of the poles in the line to build a pole identity information database.

[0045] S2. Based on the relationship between pole information in the pole identity information database, modify the latitude and longitude coordinates corresponding to the pole in the pole information to latitude and longitude line segments, and update the pole identity information database;

[0046] S3. Map the latitude and longitude lines corresponding to the pole number in the updated pole identity information database onto the GIS map. Connect several latitude and longitude lines on the GIS map to form a line, thereby forming a power facility geographic wiring diagram. Display the pole information on the power facility geographic wiring diagram using preset markers.

[0047] A further preferred technical solution is that when the drone is inspecting the line, it takes pictures of the towers in the order of their hierarchical structure, and then collects and analyzes the information from the pictures to obtain tower information.

[0048] The process of constructing the pole and tower identity information database is as follows: the table is defined in advance, and the corresponding pole and tower information is stored in each row in the order of the upper and lower levels of the poles and towers in the line. The pole and tower name in the information is used as the column header of each column in each row, and the latitude and longitude coordinates in the information of the pole and tower are stored in other columns.

[0049] A further preferred technical solution is that the pole information includes pole name, latitude and longitude coordinates, photo taking time, voltage level, line name, turning angle, altitude, pole type, span, total number of defects, tree obstructions, defect information, guy wire insulation, ancillary facilities, number of guy wires, license plate status, conductor type, number of circuits, conductor joints, pole material, crossing area, guy wire model, insulator type, geographical environment, three-wire connection, high and low voltage on the same pole, and conductor model. The latitude and longitude coordinates are composed of longitude and latitude.

[0050] Specifically, the pole and tower identity information database refers to a table that presents comprehensive pole and tower information. Before the table is preprocessed, the pole and tower information is analyzed by the images collected by the UAV inspection, resulting in Table 1 as shown below. Table 1 is the unprocessed table. The longitude and latitude in Table 1 form the longitude and latitude points, which represent the location information of the pole and tower.

[0051] Table 1

[0052]

[0053] A further preferred technical solution is that the process of associating the corresponding tower information according to the hierarchical order of the towers in the line is as follows: add a column to the table, which is defined as the name of the superior tower. Find the name of the superior tower corresponding to the tower name in each row according to the hierarchical order of the towers in the line, and fill it into the column.

[0054] Specifically, as shown in Table 2, a column can be added to Table 1 according to the hierarchical order of the towers in the line, namely, the name of the superior tower. The relationship between the tower information is established through the tower name and the superior tower name, and the table is preprocessed according to the relationship.

[0055] Table 2

[0056]

[0057] A further preferred technical solution is that the process of updating the pole identification information database is as follows:

[0058] In each row of the pole identity information database, find the name and latitude / longitude coordinates of the superior pole and use the latitude / longitude coordinates as the starting coordinates; locate the row containing the superior pole based on its name and extract the corresponding latitude / longitude coordinates, using the latitude / longitude coordinates as the ending coordinates.

[0059] Modify the definition of latitude and longitude coordinates in each row of the table to the starting coordinates; and add a column to the table, which is defined as the ending coordinates. Then connect the starting and ending coordinates in each row to form a latitude and longitude line segment to update the tower identity information database.

[0060] Specifically, Table 2 is preprocessed by modifying the latitude and longitude points in Table 2 into latitude and longitude line segments, updating Table 2 to Table 3. In Table 3, the starting point x and starting point y form the latitude and longitude coordinate points in Table 2, which are then modified into starting coordinate points. Then, based on the added column of upper-level tower names in Table 2, the ending point x and ending point y are added to Table 3. The ending point x and ending point y are the latitude and longitude coordinate points of the upper-level towers, forming the ending coordinate points. Finally, the starting and ending coordinate points are connected to form latitude and longitude line segments.

[0061] Table 3

[0062]

[0063] In summary, the latitude and longitude lines corresponding to the poles are extracted from the pole information collection table, mapped onto a GIS map, and then connected to form a route on the GIS map using several latitude and longitude lines. Various ancillary facilities in the pole information are displayed using different preset markers, such as... Figure 4 As shown.

[0064] A further preferred technical solution is that the process of displaying pole and tower information on a geographical wiring diagram of power facilities through preset markers includes the following steps:

[0065] SA1. Obtain a defect summary table obtained by performing defect data mining and analysis on the tower identity information database. Extract the defect classification and defect nature corresponding to the tower from the defect summary table, and package the component types and defect nature corresponding to the tower according to the same defect classification to form defect classification data.

[0066] SA2. Based on the first weight value corresponding to the defect nature, the same defect classification data are fused into a first defect degree, and the result of the first defect degree fusion is displayed at the towers on the power facility geographical wiring map through different color markers to form a first line defect distribution map.

[0067] SA3. Based on the first weight value corresponding to the defect nature and the second weight value corresponding to the defect classification, the defect data is fused into a second defect degree. The result of the second defect degree fusion is displayed at the towers on the power facility geographic wiring map through different color markers to form a second line defect distribution map.

[0068] Different first-line defect distribution maps are generated based on different defect classifications. The first-line defect distribution map is used to show the degree of defect of the towers on the GIS map under the same defect classification. The second-line defect distribution map is used to show the degree of defect of the towers on the GIS map under the overall situation.

[0069] A further preferred technical solution is that the process of performing defect data mining and analysis on the pole identification information database to obtain a defect summary table is as follows:

[0070] The system extracts images of poles with defects from the pole identity information database, analyzes the defective targets in the images to obtain the component types and defect descriptions of the defective targets.

[0071] By classifying the types of components, the defect categories corresponding to the defect targets are obtained;

[0072] Call the defect nature determination conditions corresponding to the component type, analyze and determine the component defect description according to the defect nature determination conditions, and obtain the defect nature corresponding to the defect target;

[0073] Construct a defect summary table based on the defect targets, component types, component defect descriptions, defect classifications, and defect properties corresponding to the towers.

[0074] A further preferred technical solution is to analyze the defective targets in the captured images. The analysis may be performed manually or through an AI model to obtain the component type and component defect description corresponding to the defective targets.

[0075] In one embodiment, since power poles in real-world scenarios have many types of components, including tension clamps, conductors, signs, etc., and different maintenance strategies are required for defects in different types of components, this application considers the types of components and the corresponding defect descriptions. By analyzing the types of components and the defect descriptions, the nature of the defect corresponding to the current type of component can be determined. The determination process is as follows: the defect nature determination conditions corresponding to the type of component are called for analysis and judgment, and the nature of the defect is determined to be a general defect / serious defect / critical defect. The defect nature determination conditions are standard conditions, which will not be elaborated here. This invention can obtain the defect severity of the component type corresponding to the defect target on the power pole. By integrating the defect severity of all component types on the power pole, the overall defect level of the current power pole can be obtained, i.e., the overall defect level. The different overall defect levels corresponding to different power poles are displayed on the GIS map using different color markers, which allows staff to intuitively see the defects of the power pole, providing decision support for defect elimination and power pole optimization.

[0076] In real-world scenarios, after analyzing the types of defective components, eight typical application scenarios were identified. These components were then categorized into eight major types, as described in this embodiment: hardware, poles, insulators, auxiliary facilities, conductors, channel environment, foundations, and grounding devices. Furthermore, defect analysis of different component types within the same defect category can be mutually influential. Therefore, this invention proposes two types of line defect distribution maps: one integrates the defect severity of all component types on the pole, visually representing the overall defect severity of the pole; the other pre-classifies component types on the pole for different application scenarios, integrating the defect severity of component types belonging to the same defect category on the pole, visually representing the predominant defect severity of the pole in different application scenarios, providing customers with diverse options suitable for various application scenarios.

[0077] Specifically, the nature of the defects includes general defects, serious defects, and critical defects. Different first weight values can be set in advance for different defect natures under different defect classifications. At this time, the first weight values of the same defect nature under different defect classifications can be the same or different. For example, generally, general defects are set as q1, serious defects as q2, and critical defects as q3, and q1 < q2 < q3. The first defect degree fusion is performed on the defect classification data according to the first weight value corresponding to the defect nature. Since the same defect classification is targeted at this time, the same base number a can be set. The first defect degree fusion is to add the first weight values of the corresponding defect targets under the same defect classification, and multiply the sum by the same base number a. For example: In an application scenario with a base number of a, Tower A has two defect targets, which respectively correspond to general defects and serious defects. Then, through the first defect degree fusion, a*(q1 + q2) is obtained; Tower B has two defect targets, which respectively correspond to general defects and critical defects. Then, through the first defect degree fusion, a*(q1 + q3) is obtained; It can be seen that a*(q1 + q2) < a*(q1 + q3). Then, the different degrees of defects of Tower A and Tower B in this application scenario can be displayed on the GIS map through different color markings.

[0078] Based on the above principle, the process of the second defect degree fusion can be obtained. Different second weight values are set for different defect classifications, and different defect classifications are substituted into the calculation process, that is, different base numbers can be set to obtain the defect degree of the tower under the overall situation. Specifically, not only can the defect degree of the tower when the defect classification is fittings be displayed through the first line defect distribution map, but also the defect degree of the tower under the overall situation can be displayed through the second line defect distribution map. Then, through different color markings and explanations of the color markings, the staff can directly see the defects of the tower, providing decision support for defect elimination and assisting in optimizing the tower. Moreover, the overweight defect degrees of the tower in different application scenarios can be visually displayed, providing diverse choices for customers and generating maintenance strategies.
