Description

Technical Field

[0001] This invention belongs to the field of digital design of wind power generation and power engineering, specifically involving computer-aided design (CAD) and automated layout of transmission lines, and particularly relates to a novel method and electronic equipment for the layout of overhead towers for onshore wind power collection lines. Background Technology

[0002] With the large-scale development of onshore wind power, the layout of overhead transmission towers has become a crucial step in the feasibility study and preliminary design phases. The tower layout process for wind power transmission lines typically involves multiple steps, including line identification, tower type determination, tower location allocation, sensitive area avoidance, tower numbering, and drawing preparation. The above process generally suffers from the following problems: 1. Traditional tower layout methods rely on manual placement and numbering of towers on CAD drawings, which is inefficient and prone to data errors. After the wind turbine or line is modified, the work needs to be redone, resulting in a lot of repetitive work and low design efficiency.

[0003] 2. In the current process of deploying poles and towers, the type of poles and towers is usually determined by the personal experience of the designers, without standardized judgment rules, resulting in insufficient design standardization. At the same time, the work of avoiding sensitive areas such as ecological red lines and basic farmland also requires repeated manual adjustments, making it difficult to ensure the optimal route plan.

[0004] 3. Some existing tower layout design software supports tower placement, but requires manual delineation of paths and tower positions. There is a lack of a fully automated solution that can automatically parse line topology, intelligently determine tower type, automatically generate numbers, avoid sensitive areas, and generate CAD drawings.

[0005] Therefore, there is an urgent need to design a new method and electronic equipment for the installation of overhead towers for onshore wind power collector lines to improve the efficiency, standardization and automation of the installation of overhead towers for wind power collector lines. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a novel method and electronic equipment for the installation of overhead towers for onshore wind power collector lines. It integrates topology tracing, angle bisector geometry determination, hierarchical progressive numbering, and ray avoidance technology to achieve full automation of the wind power collector line tower installation process.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A novel method for arranging overhead towers for onshore wind power collector lines includes the following steps: S1. Scan and obtain the data of the overhead line layer in the CAD drawing, extract the overhead line segments based on the obtained data, and construct the line topology dataset based on the overhead line segment data; S2. Based on the aforementioned line topology dataset, a topology tracing method is adopted. Starting from each wind turbine, the connected line segments are recursively searched through endpoint matching. Based on the obtained wind turbine grouping information, the line topology paths of the main path and branch path are identified and formed, and the corresponding group numbers are assigned to the lines. S3. Based on the line topology, calculate and determine the node angle feature vector and the direction vector of the connected line segment. Combine the number of connected line segments and the size of the angle to determine the tower type information. S4. Based on the preset span, automatically generate the tower placement points on all overhead lines, and simultaneously combine the tower type determination rules described in S3 to assign tower attributes to each tower. The tower attributes include at least one or more of the following: type, angle, and group code. S5. Conduct sensitive area detection on the tower deployment points, move all towers located in sensitive areas to external compliant locations and verify whether the deployment of the points complies with the specifications. S6. Based on the line topology, distinguish the line type and complete the tower grouping. Use hierarchical progressive numbering to number the tower groups, obtain the corresponding tower numbering information, and verify the uniqueness of the numbering. S7. Based on the tower layout locations and the numbering information, automatically generate CAD tower blocks and annotation information, and output CAD drawings of overhead line tower layout.

[0008] The construction of the line topology dataset in S1 specifically includes: Iterate through the data of the overhead line layer, wind turbine layer, and substation layer in the CAD drawing, and extract the overhead line segment, wind turbine coordinates, and substation coordinates respectively based on the obtained data; A line topology dataset is constructed using the data of the overhead line segments, and the line segment information is encapsulated by a custom class object; Establish a correspondence between the custom class object and the original CAD line segment object to complete the spatial index construction.

[0009] The topology tracing method in S2 specifically includes: Initialize the overhead line segment occupancy status, segment group code, and various line sets; Based on the wind turbine grouping information, starting from the wind turbine coordinates, the endpoints of the overhead power line segments are searched as the starting search nodes; Recursively search for connected line segments by endpoint matching, and mark the occupancy status and assign corresponding group numbers to the line segments in the path; When a three-way or multi-segment connection node is found, the line connection relationship is determined based on the occupancy status and group number of the connected segments. After the iteration was completed, the lines were classified and distinguished into single-circuit main lines, single-circuit branch lines, and double-circuit overhead lines.

[0010] The tower type information in S3 specifically includes; A direction vector is constructed for the connecting segments of the overhead line, and the included angle feature vector is obtained by normalized summation to characterize the turning direction and angle of the line. Tower types are classified based on the location of line nodes, the number of connecting line segments, and the characteristics of the included angle of the line segments; The tower orientation angle is set according to the tower type. The angle of the straight tower is taken from the slope angle of the line segment. The angle of the corner tower is taken from the direction of the angle bisector of the angle between the connected line segments. The T-junction tower determines the comprehensive orientation by iterating the angle bisector method. The angle of the terminal tower is consistent with the slope angle of the first and last line segments.

[0011] The automatic generation of tower placement locations and the assignment of tower attributes to each tower in S4 specifically include: Using the starting point of the line as the layout benchmark and setting a preset span, the tower coordinates are calculated and generated along the line using linear interpolation. Towers are forcibly installed at the nodes corresponding to corner towers and T-junction towers, and the spacing between adjacent spans is adaptively adjusted to ensure uniform installation. Terminal towers are installed at the end of the line; Based on the location mapping of the tower points, the corresponding tower type and angle parameters are matched. The towers inherit the group code of the line they belong to, and the towers that intersect with double-circuit lines use combined codes. Complete the assignment of all tower attributes and generate the tower layout plan.

[0012] The sensitive area detection in S5 specifically includes: Scan the sensitive area layer of the CAD drawing and extract the closed polygon data of the sensitive area; The ray method is used to determine whether the tower location is within a sensitive area by statistically analyzing the parity of the number of intersections between horizontal rays and polygon boundaries. The poles and towers in the sensitive area will be moved along the line direction to the nearest compliant location outside the area, and the distance between them and the sensitive area will be controlled to be no less than the preset threshold. The spacing of the relocated towers is checked. If the spacing does not meet the standard, the towers are deleted. If the spacing meets the standard, the front and rear spans are adaptively adjusted. Repeatedly check and adjust until all towers are outside the sensitive area and the deployment is compliant.

[0013] The hierarchical progressive numbering method in S6 specifically includes: Towers are grouped according to line type, the main line intersection towers corresponding to branch lines are identified, and custom numbering prefixes are supported; For single-circuit main line and double-circuit line towers, they are numbered sequentially along the line using a combination of group coding and sequential numbers; Branch line towers are numbered by prefixing the tower number at the intersection of the main line with an incremental suffix number. After completing the numbering, verify the uniqueness of the number and generate the tower numbering scheme.

[0014] The automatic generation of CAD pole and tower blocks and annotation information in S7, and the output of CAD drawings for the layout of overhead line poles and towers, includes the following specific steps: Create a tower drawing layer; Traverse all final tower locations, insert the corresponding tower blocks according to the preset ratio, and rotate the blocks according to the tower angle; Generate numbered text that matches a preset style next to the tower, and the text angle is synchronized with the tower angle. Verify the consistency of the pole locations, quantities, and numbering, and finally output CAD drawings of the overhead line pole layout.

[0015] The present invention also discloses an electronic device, comprising: at least one processor, at least one memory, a communication interface, and a bus; The processor, memory, and communication interface communicate with each other through the bus. The memory stores program instructions that can be executed by the processor, which calls the program instructions to implement the above-described method for the deployment of overhead towers for onshore wind power collection lines.

[0016] The present invention also discloses a computer-readable storage medium that stores computer instructions, which, when executed on a computer, cause the computer to perform the above-described method for the deployment of overhead towers for onshore wind power collection lines.

[0017] The above-described at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects: 1. This invention automatically generates the line topology path by constructing a line topology dataset and using a topology tracing method, thereby automatically generating the tower placement points and hierarchical numbering. When the line path or wind turbine connection relationship changes, the tower placement points and numbering information can be automatically adjusted based on the updated line topology path, reducing repetitive manual work and improving design efficiency.

[0018] 2. This invention automatically determines the tower type information based on the line topology path and verifies and adjusts the tower placement points by combining sensitive area detection, thereby achieving automatic optimization of the tower placement scheme and improving the standardization and accuracy of tower placement.

[0019] 3. This invention integrates line topology path identification, pole type information determination, pole layout point generation, hierarchical progressive numbering, and CAD pole block and annotation information generation to achieve automatic output of CAD drawings for overhead line pole layout, thereby improving the automation level and efficiency of engineering design.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0023] Figure 1 This is a flowchart illustrating the overall process architecture of a novel method for deploying overhead towers for onshore wind power data collection lines, provided by an embodiment of the present invention. This embodiment is applicable to the automated deployment of overhead towers for onshore wind power data collection lines, effectively solving technical problems such as low efficiency of manual deployment, lack of unified standards for tower type determination, cumbersome sensitive area avoidance, chaotic numbering, and the inability to automate the entire process. This method can be executed by an automated tower deployment device, which is implemented in hardware and / or software and can be configured in electronic devices with data processing capabilities. Figure 1 As shown, the specific process of the overhead tower layout method for onshore wind power collection lines includes: S1. Scan and obtain the data of the overhead line layer in the CAD drawing, extract the overhead line segments based on the obtained data, and construct the line topology dataset based on the overhead line segment data.

[0024] Specifically, the process for constructing the line topology dataset is as follows: Traverse the CAD drawings, extract polylines or straight lines located on the overhead line layer, and record the vertex coordinates, color, and length information of these line segments; at the same time, extract the wind turbine pattern and wind turbine number from the wind turbine layer, and obtain the center coordinates and number of the wind turbine; extract the substation pattern from the substation layer, and calculate the geometric center of the substation pattern as the location of the substation. All extracted overhead line segments are used as the core data of the line topology dataset. In the programming, a custom class object is used to store the vertex coordinates, color, length and other information of each overhead line segment, and the abstraction of the overhead line segment object in the drawing is completed. Next, establish a one-to-one mapping relationship between the custom class object storing line segment information and the original line segment object in the CAD drawing, thus completing the creation of the spatial index.

[0025] S2. Based on the aforementioned route topology dataset, a topology tracing method is adopted. Starting from each wind turbine, the connected line segments are recursively searched through endpoint matching. Based on the obtained wind turbine grouping information, the route topology paths of the main path and branch paths are identified and formed, and corresponding group numbers are assigned to the routes.

[0026] Specifically, such as Figure 2 As shown, the specific process of the topology tracing method is as follows: 1. Data Preparation and Initialization: Call the overhead line segment data set constructed in the first step, initialize the segment occupancy status flag to identify whether a segment has been included in a complete overhead line; initialize the segment group code to identify the wind turbine group to which a segment belongs (a single-circuit overhead line corresponds to a single wind turbine group, and a double-circuit overhead line corresponds to two wind turbine groups); at the same time, initialize three line sets, namely the overhead main line set, the overhead branch line set, and the overhead double-circuit line set for each group of wind turbines, for classifying and storing various types of lines generated subsequently.

[0027] 2. Multi-source concurrent retrieval: Based on the wind turbine grouping information input by the user, starting from the coordinates of each wind turbine, search for the endpoints of line segments with a distance less than a set threshold in the initial set of overhead line segments, and use them as the starting retrieval node for each path.

[0028] 3. Path recursive splicing, occupation and number assignment: The first line segment found is marked as occupied, and a corresponding single-loop group number is assigned to the line segment according to the group of the corresponding wind turbine (e.g., if the wind turbine belongs to group A, the line segment number is A; if it belongs to group B, the number is B). Then, continue to search for connected line segments along the other endpoint of the line segment. If only one unoccupied connected line segment is found, it is directly included in the current path, marked as occupied, and the single-loop group number of the current path is used. This process is recursively extended until a three-way or higher node is encountered or no new line segment can be searched.

[0029] 4. Logical determination for nodes with three or more branches: When a node with three or more branches is retrieved, the determination is made based on the occupancy status of each connecting segment in three cases, as follows: (1) If there is only one unoccupied line segment and multiple occupied line segments have the same group number, then the node is determined to be the intersection point of the single-circuit overhead line in the same group of wind turbines. At this time, the only unoccupied line segment still belongs to the single-circuit overhead line of the group of wind turbines and uses the current single-circuit group number. At the same time, the main line and branch line are distinguished according to the length of all the intersecting lines at the node. The longest line is taken as the main line of the single-circuit overhead line, and the rest are taken as branches. The only unoccupied line segment is included in the main line path and marked as occupied, and the recursive extension continues.

[0030] (2) If there is only one unoccupied line segment, but multiple occupied line segments have different group numbers (e.g., group A and group B), then the node is determined to be the intersection point of the double-circuit overhead line between different groups of wind turbines. At this time, the only unoccupied line segment is included in the double-circuit overhead line of the corresponding wind turbine groups, and is used as the starting line segment of the double-circuit overhead line for continued iteration. The group number combination of the intersecting wind turbine groups is used as the group number of the double-circuit line (e.g., group A and group B intersect, and the number is AB).

[0031] (3) If there are multiple unoccupied line segments, all other feasible branches are simultaneously traced downwards to achieve simultaneous exploration of multiple paths until only one unoccupied line segment remains at the node. If multiple unoccupied overhead line segments still exist after traversing to a certain node, an error reporting mechanism is triggered. When no new connecting line segments can be retrieved for a certain path, the iteration of the path is terminated, and it is determined whether the overhead line corresponding to the path has reached the booster station (i.e., the distance between the end point of the line and the coordinates of the booster station is less than the set threshold).

[0032] 5. Path generation and differentiation: After all path iterations are completed, each type of line is assigned to its corresponding set, resulting in the single-circuit overhead trunk line, single-circuit overhead branch line, and double-circuit overhead line between different wind turbine groups for each group of wind turbines, thus completing the classification and differentiation of the lines.

[0033] S3. Based on the line topology, calculate and determine the node angle feature vector and the direction vector of the connected line segment. Combine the number of connected line segments and the size of the angle to determine the tower type information.

[0034] Specifically, based on the angle bisector calculation method, the included angle and directional characteristics of the connected segments on the overhead line are determined. Combined with the path topology, a unified standard for determining the tower type and the corresponding angle setting specifications are formulated. Among them, the intersection point (end point) of the line segment is a mandatory tower location, and the tower locations on the line segment (excluding the end point) are preset as straight towers.

[0035] like Figure 3 As shown, the information for determining the tower type specifically includes: 1. Calculation of Direction and Angle of Connecting Line Segments: For any complete overhead line (including single-circuit main lines, single-circuit branch lines, and double-circuit lines), extract the two connecting line segments along its path, and construct the direction vectors of the preceding and following line segments respectively. By normalizing the two vectors and summing them, the characteristic vector of the angle between the two line segments is calculated, which represents the turning direction and angle of the line segment.

[0036] 2. Rules for determining the core structure of a tower: (1) Terminal tower: The starting point (wind turbine end) and ending point (booster station end) of any line are directly identified as terminal towers.

[0037] (2) T-connection tower: If a node is connected to 3 or more line segments at the same time, it is determined to be a T-connection tower.

[0038] (3) Corner tower and straight tower (at the node): If the node is connected by only two line segments, the determination is made based on the angle between the two vectors. If the angle is less than the preset threshold α, for example, set to 10°, it is determined to be a straight tower; if the angle is greater than or equal to the threshold α, it is determined to be a corner tower.

[0039] (4) Straight-line towers (within the line segment): Towers located in the middle area (not the endpoint) of the line segment are uniformly judged as straight-line towers.

[0040] 3. Standard for tower angle setting: (1) Straight-line tower (including line segment and small angle node): The angle of the straight-line tower is set as the slope angle of the line segment in which the straight-line tower is located; (2) Angle Tower: The angle of the angle tower is set as the direction of the angle bisector of the angle between two connected line segments, that is, the direction of the sum vector after adding the two unitized direction vectors is determined.

[0041] (3) T-connection tower: The angle of the T-connection tower is obtained by iterating the angle bisector. That is, first calculate the angle bisector of any two line segments, then calculate the angle between the angle bisector and the next adjacent line segment and take its angle bisector. By analogy, the final comprehensive direction is the orientation of the T-connection tower.

[0042] (4) Terminal tower: The angle of the terminal tower is consistent with the slope angle of the first and last segments of the line.

[0043] S4. Based on the preset span, automatically generate the tower placement points on all overhead lines, and simultaneously combine the tower type determination rules described in S3 to assign tower attributes to each tower. The tower attributes include at least one or more of the following: type, angle, and group code.

[0044] The process of automatically generating tower placement locations and assigning tower attributes to each tower is as follows: 1. Initialization of pole placement: For each overhead line, take the starting point of the line (i.e., the wind turbine) as the first reference point, and plan the pole placement positions segment by segment along the line extension direction according to the preset design span d, for example, set to 200 meters.

[0045] 2. Point generation and range matching: (1) Along the line direction, the spatial coordinates of each tower are calculated by linear interpolation according to the span d. The coordinates are calculated directly based on the distance between two points on the line segment, and the interpolation positioning is completed by the distance correspondence. (2) When the path traverses to the node corresponding to the corner tower or T-junction tower determined in S3, the corresponding type of tower is forcibly deployed at the node location, and the values ​​of the two spans before the node are adjusted simultaneously. For example, if the two spans before the connection node are 200 meters and 350 meters respectively, they are adjusted to 275 meters and 275 meters, that is, the position of the previous tower is adjusted to make the two spans evenly distributed, ensuring that the tower deployment density is evenly distributed.

[0046] 3. Attribute Assignment and Final Deployment: (1) Install terminal towers at the end of each line (i.e., at the substation) to complete the coverage of all overhead line tower locations; (2) Traverse all generated tower locations and directly map the judgment results in S3 according to their location (endpoint, node, line segment). Assign the corresponding tower type and angle parameters to each tower. (3) Assignment of pole group code: The pole group code inherits the group code of the line it is located on. That is, if the line where the pole is located is a single-circuit line (such as group A or group B), then the pole group code is consistent with the line (corresponding to A or B); if the pole is located at the intersection of line segments and corresponds to a double-circuit line (such as group AB), then the pole group code adopts the combination code of the double-circuit line (corresponding to AB). For example, the poles that intersect with single-circuit line A, single-circuit line B and double-circuit line AB have the group code AB. (4) Complete the assignment of attributes to all towers and finally generate a complete tower layout scheme that conforms to engineering design specifications.

[0047] S5. Conduct sensitive area detection on the tower deployment points, move all towers located in sensitive areas to external compliant locations, and verify whether the deployment of the points complies with the specifications.

[0048] like Figure 5 As shown, the specific process for detecting the sensitive area is as follows: 1. Sensitive Area Acquisition: Scan the sensitive area layer in the CAD drawing, extract the shape data of the sensitive areas (such as ecological red lines and mining areas), and complete the sensitive area initialization; 2. Tower Location Detection: The ray casting method is used to check whether each of the deployed tower locations is located inside the sensitive area. The specific detection logic is as follows: For each tower location, a horizontal ray is cast to the right from that point, and the number of intersections between the ray and the boundary of the closed polygon of the sensitive area is counted. If the number of intersections is odd, the tower location is determined to be inside the sensitive area; if the number is even, the tower location is determined to be outside the sensitive area and no adjustment is required. 3. Adjustment of poles in sensitive areas: For poles determined to be located inside sensitive areas, search for suitable deployment points in the area in front of and behind the pole along the extension direction of the overhead line where it is located, and move the pole to the nearest deployment point outside the sensitive area, and ensure that the distance between the pole and the sensitive area after the move is not less than a preset threshold (e.g., set to 30 meters). 4. Post-adjustment verification and processing: After the tower is moved, a second verification is performed on the tower. If the distance between the moved tower and other surrounding towers is less than the preset safety distance (e.g., set to 30 meters), the tower is directly deleted. If the distance meets the safety requirements, the tower is retained, and the span before and after the tower is adjusted simultaneously to ensure a uniform distribution of tower density. 5. Overall verification: Repeat steps 2 to 4 above until all poles in sensitive areas have been adjusted, verified and processed to ensure that all remaining poles are located outside the sensitive areas and are deployed in accordance with the specifications.

[0049] In one optional implementation, the deployment method further includes: when there are no sensitive area deployment requirements for the project, skip the sensitive area avoidance step directly, and after completing the generation and attribute assignment of S4 pole and tower locations, directly execute the S6 pole and tower grouping and numbering step.

[0050] S6. Based on the line topology, distinguish the line type and group the towers. Use hierarchical progressive numbering to number the tower groups, obtain the corresponding numbering information for the towers, and verify the uniqueness of the numbering.

[0051] like Figure 4 As shown, the hierarchical progressive numbering method specifically includes: 1. Preliminary preparation for numbering: First, group all the completed towers according to the line type, distinguish between single-circuit main lines, double-circuit lines and single-circuit branch lines, and identify the main line intersection towers corresponding to each branch line. At the same time, the numbering prefix can be customized and adjusted.

[0052] 2. Numbering of Main Line and Double-Circuit Towers: Towers on single-circuit main lines and double-circuit lines are prioritized for numbering. The numbering logic is "tower group code + sequential number". Starting from the wind turbine at the beginning of each line, the towers are numbered sequentially along the line extension direction (towards the substation). For example, the tower numbers for single-circuit main lines are A1, A2, A3... (corresponding to group A main lines), B1, B2, B3... (corresponding to group B main lines); the tower numbers for double-circuit lines are AB1, AB2, AB3... (corresponding to group AB double-circuit lines), CD1, CD2, CD3... (corresponding to group CD double-circuit lines). The sequential numbers start from 1 and increase sequentially to ensure that the numbers are unique and continuous.

[0053] 3. Branch Line Tower Numbering: Branch line towers are numbered by prefixing the tower number of the intersection point with their respective main line and adding a "-sequential number" as a suffix to achieve semantic association between the branch line and the main line. Specifically, first determine the tower number corresponding to the intersection point of the branch line and the main line (i.e., the main line tower number at the intersection node of the branch line and the main line), and then start from the starting point of the branch line (at the wind turbine) and number it sequentially along the extension direction of the branch line, with the suffix number increasing sequentially from 1. For example, if the intersection point of a branch line and the main line of group A is tower A5, then the tower numbers of the branch line are A5-1, A5-2, A5-3, and so on.

[0054] 4. Numbering Verification and Confirmation: After numbering is completed, the uniqueness of all pole numbers is automatically verified to ensure that there are no duplicates or omissions, and finally a set of pole numbering schemes that are semantically clear, logically coherent and traceable is generated.

[0055] S7. Based on the tower layout locations and the numbering information, automatically generate CAD tower blocks and annotation information, and output CAD drawings of overhead line tower layout.

[0056] The automatic generation of CAD pole and tower diagrams and annotation information, and the output of CAD drawings for overhead line pole and tower layout, includes the following steps: 1. Initialize the drawing environment: Create and name a dedicated layer, set the layer properties, and use it as the carrying layer for all tower blocks and numbers, which will facilitate subsequent editing and management.

[0057] 2. Precise drawing of tower blocks: The built-in tower block reference insertion function in CAD is called to traverse all the final tower locations after verification; at each location, the corresponding tower base block is inserted according to the preset ratio, and the block direction is rotated synchronously according to the angle attribute of the tower to ensure that the drawn tower matches the route and angle perfectly.

[0058] 3. Numbering and Style Settings: A text object is generated next to each tower block to display the final number of the tower in a preset font, font height, and color. To ensure visual consistency in the drawings, the rotation angle of the text object is set to match the angle of the corresponding tower to ensure an aesthetically pleasing overall layout and clear direction.

[0059] 4. Results Integration and Finalization: After completing the drawing of all pole and tower blocks and numbers, the system automatically verifies the consistency of the number, location and number of poles and towers in the drawings, and finally outputs a complete, standardized CAD drawing of overhead line pole and tower layout that can be directly used for engineering design and approval.

[0060] It is understood that the technical solutions described above are not only applicable to the deployment of overhead towers for onshore wind power collection lines, but also to the automated deployment of towers for other power overhead lines such as transmission and distribution lines and photovoltaic collection lines, as long as they can achieve line topology identification, intelligent tower type determination, automatic tower numbering, and automated CAD drawing output.
