Description

Technical Field

[0001] This invention relates to the field of power transmission line engineering technology, and in particular to an automatic optimization method, device, terminal and storage medium for tower arrangement. Background Technology

[0002] In power transmission line engineering, the tower installation stage is an essential part of the design phase for a new line. During tower installation, appropriate tower types must be selected based on the different locations of the line. Tension towers are required at angle stakes, and the distance between towers must meet the required vertical span. Several necessary factors must be considered during tower erection: such as preventing towers from being pulled upwards, ensuring the distance from the lowest point of the conductor to the ground meets safety requirements, and ensuring the stringing between towers meets the set kV values.

[0003] Currently, the most common method for constructing three-dimensional transmission line towers involves designing the required tower types, conductors, and terminal tower types, then using the tension section as the starting point, calculating and verifying the towers step-by-step from the end of the tension section forward, with a predetermined step length. The tower is erected when all necessary conditions are met. However, this method suffers from drawbacks because the selected line is very long and has many tower locations, resulting in numerous possible solutions. Furthermore, it doesn't consider the overall plan, leading to situations where the last span of the tension section is very short, resulting in waste and an excessive number of towers. This also increases the workload and construction time during the construction phase. Summary of the Invention

[0004] This invention provides an automatic optimization method, device, terminal, and storage medium for tower arrangement to solve the problems of small gaps in the last row and excessive number of towers in the prior art.

[0005] In a first aspect, embodiments of the present invention provide an automatic optimization tower arrangement method, comprising:

[0006] Calculate the locations of all tower erection points in the target road segment based on the step length;

[0007] The tower type for each tower erection point is determined based on the total weight of the tower and the tower arrangement data.

[0008] Each tower erection point is selected based on its tower type, and the selected points are used as the final tower erection points.

[0009] In one possible implementation, the tower arrangement data includes:

[0010] Tower model data and basic data for tower arrangement;

[0011] The tower model data includes the tower model, height, weight, allowable horizontal span value, allowable vertical span value, KV value, minimum turning angle, and maximum turning angle; among them, the weight is used to calculate the total weight of the tower;

[0012] The basic data for tower arrangement includes: the terminal tower model, minimum span, maximum span, sag K value of the overhead line, and safe distance between the transmission line and the ground.

[0013] In one possible implementation, the target road section includes multiple piles, with a tension section between two adjacent piles;

[0014] The calculation of the location of all tower erection points in the target section based on the step length includes: determining the location of all tower erection points between each tension section in sequence according to the step length.

[0015] In one possible implementation, the tower data includes the elevation values ​​of all the towers on the target road segment;

[0016] Before determining the tower type for each erection point based on the total weight of the tower and the tower arrangement data, the method also includes:

[0017] Obtain the cumulative distance and elevation values ​​of the intermediate cross-section points in the target road segment; where the intermediate cross-section points are the measured points on the intermediate cross-section line; the cumulative distance value of the intermediate cross-section points is the cumulative step size from the starting measured point to the current measured point, denoted as Sp1;

[0018] The step lengths between the starting piles of each tension section and the current tower erection point are accumulated to obtain the cumulative distance value of the current tower erection point, denoted as Sp2.

[0019] Check if the cumulative distance value Sp1 of the intermediate cross-section point is equal to the cumulative distance value Sp2 of the current tower point; if it is, set the elevation value of the current tower point to the elevation value of the intermediate cross-section point.

[0020] If it does not exist, then find all Sp1 values ​​greater than Sp2 and all Sp1 values ​​less than Sp2; among them, the center section point with the smallest cumulative distance value among all Sp1 values ​​greater than Sp2 is denoted as P1; the center section point with the largest cumulative distance value among all Sp1 values ​​less than Sp2 is denoted as P2.

[0021] Calculate the current elevation of the tower erection point based on the cumulative distance and elevation values ​​of P1 and P2, and the elevation calculation formula; where the elevation calculation formula is:

[0022] h=(h1-h2)÷(d1-d2)×(Sp2-d2)+h2;

[0023] Wherein, d1 and h1 are the cumulative distance and elevation values ​​of the central section point P1, and d2 and h2 are the cumulative distance and elevation values ​​of the central section point P2.

[0024] In one possible implementation, the tower model for determining the intermediate tower erection point based on the total weight of the tower and overall factors includes:

[0025] Determine the cumulative distance value corresponding to each tower erection point;

[0026] Arrange all tower erection points in ascending order of cumulative distance value;

[0027] A terminal tower is established at the first tower erection point, which is called the current tower erection point. After entering the next point, this point is set as the current tower erection point. The total weight of the current tower erection point is the sum of the weights of all towers at all tower erection points from the first tower erection point to the current tower erection point, as well as the smaller side towers connected to the towers at the tower erection point.

[0028] The available tower models and available smaller side tower models at the current tower erection point are matched to obtain multiple candidate tower models corresponding to the current tower erection point; wherein, each candidate tower model includes one tower model that can be erected at the current tower erection point and a tower at a smaller side tower erection point that matches the tower model;

[0029] If there are multiple candidate tower models that meet all the tower erection conditions at the current tower erection point, then the candidate tower model with the smallest weight recorded at the current tower erection point is selected as the tower model for the current tower erection point.

[0030] If there are multiple smaller tower locations for a tower model at the current tower location that meet the above conditions, then the tower model at the tower location with the smallest weight is selected as the smaller tower.

[0031] When multiple candidate tower models at the current tower erection point match and meet all tower erection conditions, the current tower model is retained; where the weight value Spwei of the current tower erection point is:

[0032] Spwei = Spwei1 + weiTower;

[0033] Where Spwei1 is the total weight of the smaller side towers connected to the towers at the first tower point to the current tower point, and weiTower is the total weight of the towers at the first tower point to the current tower point.

[0034] In one possible implementation, the tower arrangement data also includes corners;

[0035] All tower erection conditions include:

[0036] The tower at the starting and ending piles of each tension section is called a tension tower; the actual rotation angle of the tension tower is equal to the rotation angle of its corresponding pile; the rotation angle of the pile is within the range of the first and second rotation angles of its corresponding tension tower.

[0037] The span between any two adjacent tower erection points is greater than the first span and less than the second span; however, if the two tower points are the starting or ending piles of the tension section, no judgment condition is required.

[0038] The difference between the distance to the ground and the elevation of the conductor connecting the tower at the current tower erection point and the smaller side tower is greater than the safe distance to the ground; where the difference in elevation is the difference between the elevation value at the maximum sag point of the conductor and the ground elevation value at the maximum sag point.

[0039] The actual horizontal and vertical spans of the smaller side tower at the current tower erection point are less than the allowable horizontal and vertical spans of the tower. If the tower at the current tower erection point is a tension tower, the ratio of the vertical span to the horizontal span (KV value) of the tension tower is greater than the allowable KV value of the tower. If the tower is a suspension tower, it is not necessary to determine the KV value.

[0040] In one possible implementation, if there are multiple candidate tower models that meet the tower erection conditions at the current tower erection point, then the candidate tower model with the smallest weight recorded at the current tower erection point is selected as the tower model for the current tower erection point.

[0041] If there are multiple smaller tower locations that meet the conditions for a tower model at the current tower location, then the tower model at the tower location with the smallest weight is selected as the smaller tower location and connected to it.

[0042] If there is no tower-erecting point on the smaller side that meets the conditions at the current tower-erecting point, then discard the current tower-erecting point and set the next tower-erecting point as the current tower-erecting point.

[0043] Secondly, embodiments of the present invention provide an apparatus for automatically optimizing tower arrangement, comprising:

[0044] The point calculation module is used to calculate the location of all tower erection points in the target road segment based on the step size;

[0045] The tower model determination module is used to determine the tower model for each tower erection point based on the total weight of the tower and the tower arrangement data.

[0046] The tower erection point screening module is used to screen each tower erection point according to the tower type, and the screened tower erection points are used as the final tower erection points.

[0047] Thirdly, embodiments of the present invention provide a terminal, including a memory, a processor, and a computer program stored in the memory and executable on the processor, characterized in that the processor executes the computer program to implement the steps of the first aspect or any possible implementation of the first aspect.

[0048] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing a computer program, characterized in that the computer program, when executed by a processor, implements the steps of the first aspect or any possible implementation of the first aspect.

[0049] This invention provides an automatic optimization method, device, terminal, and storage medium for tower placement. By considering the total weight of the towers and comprehensively considering the tower placement data, the optimal tower placement scheme is selected, avoiding excessively small gaps in the last span. It has the advantages of minimizing the overall number of towers and the total weight of all towers in the line, effectively reducing overall costs and construction time during the construction phase.

[0054] Figure 4 This is a schematic diagram of the terminal provided in an embodiment of the present invention. Detailed Implementation

[0055] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0056] To make the objectives, technical solutions, and advantages of the present invention clearer, specific embodiments will be described below in conjunction with the accompanying drawings.

[0057] Figure 1 This is a flowchart illustrating the implementation of an automatic optimization tower arrangement method provided in an embodiment of the present invention. Figure 1 As shown:

[0058] Step 101: Calculate the locations of all tower erection points in the target road segment based on the step length.

[0059] In this embodiment, the cumulative distance value of each possible tower erection point can be calculated by accumulating the step length in front of the tower position according to the starting position of the target line. That is, the position of each possible tower erection point is determined, thereby determining the position of all tower erection points on the target road segment. Here, the target line refers to the selected road segment where towers need to be erected. The step length can be adjusted according to actual needs and is not limited here.

[0060] Step 102: Determine the tower type for each tower erection point based on the total weight of the tower and the tower arrangement data.

[0061] In this embodiment, the terminal tower and the line have been selected before tower placement, and all tower models suitable for the current tower placement work have been preliminarily screened. When determining the tower model for the tower placement point, all suitable tower models are first screened according to the overall factors based on the tower placement data. Then, the tower with the smallest weight is selected as the intermediate tower from all suitable tower models. This achieves the technical effect of minimizing the overall weight of the towers and the number of towers along the entire tower placement line, thereby reducing tower placement costs and construction time. The overall factors may include wind speed, pressure, safety distance, elevation value, and span value on the target line, or the tower model itself, the wind speed it can withstand, and the specific span, which are not limited here.

[0062] Step 103: Select each tower erection point according to the tower type, and use the selected tower erection points as the final tower erection points.

[0063] In this embodiment, the tower erection points are screened according to the tower type of each tower erection point. The tower erection points that meet the screening conditions are retained, while those that do not meet the conditions are discarded. The screened tower erection points are used as the final tower erection points, thereby determining the final tower arrangement plan, that is, confirming the locations where towers need to be erected along the entire line and the tower types to be erected at the locations.

[0064] In summary, this embodiment provides an automatic optimization tower placement method that can calculate the locations of all tower erection points in the target road segment based on the step length; determine the tower type for each tower erection point based on the total weight of the towers and the tower placement data; filter each tower erection point based on its tower type, and use the filtered tower erection points as the final tower erection points; this embodiment considers the total weight of the towers during tower placement and can comprehensively consider the tower placement data to select the optimal tower placement scheme, avoiding excessively small last spans. It has the advantages of minimizing the overall number of towers and the total weight of all towers on the line, effectively reducing overall costs and construction time during the construction phase.

[0065] In some possible implementations, the tower arrangement data in step 102 above may include: tower model data and basic data during tower arrangement;

[0066] Tower model data may include tower model, height, weight, allowable horizontal span value, allowable vertical span value, KV value, minimum turning angle, and maximum turning angle; among which, weight is used to calculate the total weight of the tower;

[0067] Basic data for tower installation can include: the type of the terminal tower, minimum span, maximum span, sag K value of the overhead line, and safe distance between the transmission line and the ground.

[0068] In this embodiment, since the direction of the selected line and the target line is determined before the tower erection work begins, and the tower type is a property of the tower itself, all suitable tower types can be selected according to the actual selected line and direction and the properties of the tower itself, and the total weight of the tower at the tower erection point can be calculated according to the weight of the tower.

[0069] The basic data for tower arrangement are the necessary factors to be considered during the arrangement process. They can prepare data for subsequent tower arrangement and can also preliminarily eliminate tower models that do not meet the requirements.

[0070] In some possible implementations, the target road section in step 101 above may include multiple piles, with a tension section between two adjacent piles;

[0071] Accordingly, step 101 may include: determining the locations of all tower erection points between each tension section in sequence according to the step length.

[0072] In this embodiment, the target road section includes multiple piles. The positions of the piles are determined before the tower erection work begins. The area between two adjacent piles is a tension section. The entire target road section includes multiple tension sections. The two piles in a tension section can be set as the starting pile and the ending pile, respectively. When calculating the tower erection points, the starting pile of the first tension section can be used as the starting point, and then the process can be advanced according to the set step size to obtain all possible tower erection points on the current tension section. Once all possible tower erection points in the current tension section are determined, the ending pile of the current tension section can be set as the starting pile of the next tension section, thereby determining the positions of all possible tower erection points on the entire target line.

[0073] In some possible implementations, the tower data in step 102 above may also include the elevation values ​​of all the piles on the target road section;

[0074] Before determining the tower type for each erection point based on the total weight of the tower and the tower arrangement data, the process also includes:

[0075] Obtain the cumulative distance and elevation values ​​of the intermediate cross-section points in the target road segment; where the intermediate cross-section points are the measured points on the intermediate cross-section line; the cumulative distance value of the intermediate cross-section points is the cumulative step size from the starting measured point to the current measured point, denoted as Sp1;

[0076] The step lengths between the starting piles of each tension section and the current tower erection point are accumulated to obtain the cumulative distance value of the current tower erection point, denoted as Sp2.

[0077] Check if the cumulative distance value Sp1 of the intermediate cross-section point is equal to the cumulative distance value Sp2 of the current tower point; if it is, set the elevation value of the current tower point to the elevation value of the intermediate cross-section point.

[0078] If it does not exist, then find all Sp1 values ​​greater than Sp2 and all Sp1 values ​​less than Sp2; among them, the center section point with the smallest cumulative distance value among all Sp1 values ​​greater than Sp2 is denoted as P1; the center section point with the largest cumulative distance value among all Sp1 values ​​less than Sp2 is denoted as P2.

[0079] The elevation of the current tower erection point is calculated based on the cumulative distance and elevation values ​​of P1, the cumulative distance and elevation values ​​of P2, and the elevation calculation formula; wherein, the elevation calculation formula is:

[0080] h=(h1-h2)÷(d1-d2)×(Sp2-d2)+h2;

[0081] Wherein, d1 and h1 are the cumulative distance and elevation values ​​of the central section point P1, and d2 and h2 are the cumulative distance and elevation values ​​of the central section point P2.

[0082] In this embodiment, the selected transmission line is determined before the tower erection work begins. Since the tower erection work requires calculating the safe distance between the transmission line and the ground based on the elevation values ​​of the tower erection points, it is necessary to calculate the elevation value corresponding to each tower erection point after determining the tower erection points. This allows for the selection of a suitable tower type for the current tower erection point. Specifically, this can be achieved by obtaining the cumulative distance value Sp1 of the intermediate cross-section point of the selected line and the cumulative distance value Sp2 of the current tower erection point. The values ​​of Sp1 and Sp2 are compared. If there is a value of Sp1 equal to the value of Sp2, the elevation value of the current tower erection point corresponding to Sp1 is retained, and this value is set as the elevation value of the intermediate cross-section point corresponding to Sp2.

[0083] If no equal values ​​exist, then search for values ​​greater than Sp2 and less than Sp2 among all Sp1 values. The center section point with the smallest cumulative distance value among all Sp1 values ​​greater than Sp2 is denoted as P1; the center section point with the largest cumulative distance value among all Sp1 values ​​less than Sp2 is denoted as P2.

[0084] For example, h1 can be 35 meters, h2 can be 30 meters, d1 can be 5 meters, d2 can be 3.5 meters, and Sp2 can be 4 meters. Then the elevation of the current tower point can be: (35-30) / (5-3.5)*(4-3.5)+30=31.667 (meters) (the result is rounded to three decimal places).

[0085] In some possible implementations, determining the tower type at the intermediate tower erection point in step 102 above, based on the total weight of the tower and overall factors, may include:

[0086] Determine the cumulative distance value corresponding to each tower erection point;

[0087] Arrange all tower erection points in ascending order of cumulative distance value;

[0088] A terminal tower is established at the first tower erection point, which is called the current tower erection point. After entering the next point, this point is set as the current tower erection point. The total weight of the current tower erection point is the sum of the weights of all towers at all tower erection points from the first tower erection point to the current tower erection point, as well as the smaller side towers connected to the towers at the tower erection point.

[0089] Match the available tower models and available smaller side tower models at the current tower erection point to obtain multiple candidate tower models corresponding to the tower erection point; where each candidate tower model includes one tower model that can be erected at the current tower erection point and the tower at the smaller side tower erection point that matches the tower model;

[0090] If there are multiple candidate tower models that meet all the tower erection conditions at the current tower erection point, then the candidate tower model with the smallest weight recorded at the current tower erection point is selected as the tower model for the current tower erection point.

[0091] If there are multiple smaller tower locations for a tower model at the current tower location that meet the conditions, then the tower model at the tower location with the smallest weight is selected as the smaller tower.

[0092] When multiple candidate tower models at the current tower erection point match and meet all tower erection conditions, the current tower model is retained; where the weight value Spwei of the current tower erection point is:

[0093] Spwei = Spwei1 + weiTower;

[0094] Where Spwei1 is the total weight of the smaller side towers connected to the towers at the first tower point to the current tower point, and weiTower is the total weight of the towers at the first tower point to the current tower point.

[0095] In this embodiment, the tower erection points are arranged in order from near to far according to the magnitude of the cumulative distance value. The terminal tower is set at the first tower erection point in each tension section. The first tower erection point can be selected as the current tower erection point. After entering the next tower erection point, the next tower erection point can be set as the current tower erection point.

[0096] Each tower erection point has multiple available tower models and smaller side towers. The available tower models and smaller side towers can be matched to obtain multiple candidate tower models corresponding to that tower erection point. Then, all candidate tower models are filtered according to all tower erection conditions. If the current tower erection point has only one pair of candidate tower models after filtering, then this pair of candidate towers is used as the tower for the current tower erection point. If the current tower erection point has multiple pairs of candidate tower models after filtering, the principle of minimum weight is followed to ensure that the total weight of the towers at the current tower erection point is minimized. The total weight of the current tower erection point can be the sum of the weight values ​​of all towers from the first tower erection point to the current tower erection point, as well as the smaller side towers connected to the towers at the current tower erection point.

[0097] For example, when calculating the total weight of the current tower point, the weights of the smaller side towers connected to the towers from the first tower point to the current tower point can be summed to obtain the total weight of the current smaller side towers. Then, the weights of the towers from the first tower point to the current tower point can be summed to obtain the total weight of the towers at the current tower point. Finally, the total weight of the current smaller side towers can be added to the total weight of the towers at the current tower point to obtain the total weight of the current tower point.

[0098] In some possible implementations, the tower data in step 102 above may also include the rotation of the piles;

[0099] The conditions for erecting a tower include:

[0100] The tower at the starting and ending piles of each tension section is called a tension tower; the actual rotation angle of the tension tower is equal to the rotation angle of its corresponding pile; the rotation angle of the pile is within the range of the first and second rotation angles of its corresponding tension tower.

[0101] In this embodiment of the invention, the actual tower erection situation needs to be considered when designing the tower arrangement. If the current tower erection point coincides with the starting or ending pile of the tension section, then the tower used at the current tower erection point is called a tension tower. The actual rotation angle of the corresponding pile should be within the allowable rotation angle range of the tension tower. The first rotation angle can be represented as the maximum rotation angle of the tower, and the second rotation angle can be represented as the minimum rotation angle of the tower. Whether the tower can be erected at the tower erection point can be determined by whether the rotation angle of the pile is within the rotation angle range of the tower. The initially selected tower models are further screened. If the rotation angle of the current pile is within the rotation angle range of the selected tower model, then the tower can be selected as a tension tower. If it is not within the range, other tower models are screened at the current pile.

[0102] The span between any two adjacent tower erection points is greater than the first span and less than the second span; however, if the points corresponding to the two towers are the starting or ending piles of the tension section, this condition does not need to be determined.

[0103] In this embodiment of the invention, the span between the two tower erection points should be greater than the first span and less than the second span. If the corresponding tower erection points of the two towers coincide with the starting or ending pile of the tension section, it is not necessary to determine whether the span between them meets the conditions, and the towers can be erected directly. For example, the first span can be 100 meters and the second span can be 800 meters, which can be set according to the actual tower arrangement situation, and is not limited here.

[0104] For example, the first tower erection point among the two tower erection points can be set as the current tower erection point, and the second tower erection point can be set as the next tower erection point. If the span between the two towers is less than the first span, the next tower erection point is discarded, and the tower erection point after the next tower erection point is selected for connection judgment. If the span between the two towers is greater than the second span, the search for the next tower erection point to be connected to the current tower erection point ends, and the tower erection point where the termination pile of the tension section is located is set as the next tower erection point.

[0105] This invention, by screening and judging the span between any two adjacent tower erection points, can effectively avoid the last span in the tension section being too small.

[0106] The difference between the distance to the ground and the elevation of the conductor connecting the tower at the current tower erection point and the smaller side tower is greater than the safe distance to the ground. The elevation difference is the difference between the elevation value at the point of maximum sag of the conductor and the ground elevation at that point. Based on the elevation values, the safe distance between any point on the conductor and the ground can be calculated. For specific calculation methods, please refer to [link to calculation method]. Figure 2 .

[0107] Figure 2 This is a schematic diagram of the wiring for an automatic optimization tower arrangement method provided in an embodiment of the present invention, as shown below. Figure 2 As shown, the smaller side tower at the current tower erection point is tower A, and the tower at the current tower erection point is tower B. The span between tower A and tower B is dL. The elevation of the tower point where tower A is located is AHeight, and the elevation of the tower point where tower B is located is BHeight. The tower height can be considered as the distance from the suspension point on the tower to the ground, thus obtaining the elevation value of the suspension point. The elevation of the suspension point of tower A is AH, and the elevation of the suspension point of tower B is BH. Let any point on the line be p, and its elevation value be H. The elevation value of any point on the line can be calculated according to the following formula, which can be used to determine the safe distance of the point from the ground:

[0108] H = AH + x * tanβ - f

[0109]

[0110]

[0111] Where x is the difference between the cumulative distance value at point p on the line and the cumulative distance value of tower A, k is the set parameter K value, β is the elevation difference angle, l is the span, f is the sag value at point p, and f m This represents the maximum sag value.

[0112] The distance to the ground at the lowest point of the suspended conductor can be calculated using the above formula. If this distance is less than the safe distance to the ground, the corresponding smaller side tower A is discarded, and the next tower is selected for evaluation. This condition helps prevent the suspended conductor from being too low and failing to meet engineering standards, thus avoiding dangerous situations.

[0113] The actual horizontal and vertical spans of the smaller side tower at the current tower erection point are less than the allowable horizontal and vertical spans of the tower. If the tower at the current tower erection point is a tension tower, the ratio of the vertical span to the horizontal span (KV value) of the tension tower is greater than the allowable KV value of the tower. If the tower is a suspension tower, it is not necessary to determine the KV value.

[0114] In this embodiment, the tower at the current tower erection point can be tower B, and the matching smaller side tower can be tower A. The smaller side tower at the next tower erection point connected to tower A can be tower C. When selecting the smaller side tower A, it is necessary to determine whether its actual horizontal and vertical spans are less than the tower's allowable horizontal and vertical spans. If the conditions are met, tower A can be set as the smaller side tower of the current tower erection point. If the conditions are not met, it is necessary to determine whether the next smaller side tower meets the conditions. If the tower at the current tower erection point is a tension tower, it is necessary to determine whether the KV value of tower A meets the conditions. If the tower is a suspension tower, this condition determination is not required.

[0115] For example, the actual horizontal span of tower A can be Hor, and the actual vertical span can be Ver, which can be calculated according to the following formula:

[0116]

[0117]

[0118]

[0119] Where KV is the actual KV value of the tower, l AB The span between tower B and tower A, l ACLet Hor be the span of tower A and tower C. If Hor is less than the allowable horizontal span of tower A, and Ver is less than the allowable vertical span of tower A, then tower A can be designated as the smaller side tower for the current tower erection point. If the condition is not met, other smaller side towers are selected for evaluation. If the tower at the current tower erection point is a tension tower, it is necessary to calculate whether the KV value of tower A is greater than the KV value of the tower. If the condition is met, tower A can be designated as the smaller side tower for the current tower erection point. If the condition is not met, other smaller side towers are selected for evaluation. When the tower is a suspension tower, KV value evaluation is not required.

[0120] In this embodiment, tower models that meet the conditions can be selected by using all the above tower erection conditions. By considering overall factors, it is possible to effectively avoid situations where the verification fails and modifications are required, thereby improving work efficiency.

[0121] In some possible implementations, step 103 may further include:

[0122] If there is no tower-erecting point on the smaller side that meets the conditions at the current tower-erecting point, then discard the current tower-erecting point and set the next tower-erecting point as the current tower-erecting point.

[0123] In this embodiment, all tower models are filtered using all the above tower erection conditions. If no tower erection point with the smaller size meets the conditions after filtering the current tower erection point, the current tower erection point will be discarded, and the next tower erection point will be set as the current tower erection point to continue filtering.

[0124] In summary, this technology, by considering the total weight of the towers and comprehensively considering tower arrangement data, selects the optimal tower arrangement scheme, solving the problems of small last span distance and excessive number of towers in existing technologies. It avoids excessively small last span distance, has the advantages of the fewest overall towers and the smallest total weight of all towers in the line, and can effectively reduce overall costs and construction time during the construction phase.

[0125] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0126] Corresponding to the above embodiment, an automatic optimization tower arrangement method, Figure 3 This is a structural block diagram of an automatic optimization tower arrangement device provided in an embodiment of the present invention. For ease of explanation, only the parts related to the embodiments of the present invention are shown.

[0127] refer to Figure 3 The automatic tower arrangement optimization device 30 includes: a point calculation module 31, a tower type determination module 32, and a tower erection point screening module 33.

[0128] Among them, the point calculation module 31 is used to calculate the points of all tower erection points in the target road segment according to the step size;

[0129] The tower model determination module 32 is used to determine the tower model at each tower erection point based on the total weight of the tower and the tower arrangement data.

[0130] The tower erection point screening module 33 is used to screen each tower erection point according to the tower type of each tower erection point, and to use the screened tower erection points as the final tower erection points.

[0131] In some possible implementations, the tower model determination module 32 is specifically used to: acquire tower arrangement data, wherein the tower arrangement data includes: tower model data and basic data during tower arrangement;

[0132] The tower model data includes the tower model, height, weight, allowable horizontal span value, allowable vertical span value, KV value, minimum turning angle, and maximum turning angle; among them, the weight is used to calculate the total weight of the tower;

[0133] The basic data for tower arrangement includes: the terminal tower model, minimum span, maximum span, sag K value of the overhead line, and safe distance between the transmission line and the ground.

[0134] In some possible implementations, the target road section includes multiple piles, with a tension section between two adjacent piles. Accordingly, the point calculation module 31 is specifically used to determine the points of all tower erection points between each tension section in sequence according to the step length.

[0135] In some possible implementations, the tower data includes the elevation values ​​of all piles on the target road section, and correspondingly, the tower type determination module 32 is also used for:

[0136] Obtain the cumulative distance and elevation values ​​of the intermediate cross-section points in the target road segment; where the intermediate cross-section points are the measured points on the intermediate cross-section line; the cumulative distance value of the intermediate cross-section points is the cumulative step size from the starting measured point to the current measured point, denoted as Sp1;

[0137] The step lengths between the starting piles of each tension section and the current tower erection point are accumulated to obtain the cumulative distance value of the current tower erection point, denoted as Sp2.

[0138] Check if the cumulative distance value Sp1 of the intermediate cross-section point is equal to the cumulative distance value Sp2 of the current tower point; if it is, set the elevation value of the current tower point to the elevation value of the intermediate cross-section point.

[0139] If it does not exist, then find all Sp1 values ​​greater than Sp2 and all Sp1 values ​​less than Sp2; among them, the center section point with the smallest cumulative distance value among all Sp1 values ​​greater than Sp2 is denoted as P1; the center section point with the largest cumulative distance value among all Sp1 values ​​less than Sp2 is denoted as P2.

[0140] The elevation value is calculated based on the cumulative distance and elevation values ​​of P1 and P2, and the elevation value calculation formula; the elevation value calculation formula is as follows:

[0141] h=(h1-h2)÷(d1-d2)×(Sp2-d2)+h2;

[0142] Wherein, d1 and h1 are the cumulative distance and elevation values ​​of the central section point P1, and d2 and h2 are the cumulative distance and elevation values ​​of the central section point P2.

[0143] In some possible implementations, the tower model determination module 32 is specifically used to: determine the cumulative distance value corresponding to each tower erection point;

[0144] Arrange all tower erection points in ascending order of cumulative distance value;

[0145] A terminal tower is established at the first tower erection point, which is called the current tower erection point. After entering the next point, this point is set as the current tower erection point. The total weight of the current tower erection point is the sum of the weights of all towers at all tower erection points from the first tower erection point to the current tower erection point, as well as the smaller side towers connected to the towers at the tower erection point.

[0146] Match the available tower models and available smaller side tower models at the current tower erection point to obtain multiple candidate tower models corresponding to the current tower erection point; where each candidate tower model includes one tower model that can be erected at the current tower erection point and the tower at the smaller side tower erection point that matches the tower model.

[0147] If there are multiple candidate tower models that meet all the tower erection conditions at the current tower erection point, then the candidate tower model with the smallest weight recorded at the current tower erection point is selected as the tower model for the current tower erection point.

[0148] If there are multiple smaller tower locations on the same tower type at the current tower location, then the tower type at the tower location with the smallest weight is selected as the smaller tower and connected to it.

[0149] When multiple candidate tower models at the current tower erection point match and meet all tower erection conditions, the current tower model is retained; where the weight value Spwei of the current tower erection point is:

[0150] Spwei = Spwei1 + weiTower;

[0151] Wherein, Spwei1 is the total weight of the smaller side towers connected to the towers at the first tower point to the current tower point, and weiTower is the total weight of the towers at the first tower point to the current tower point.

[0152] In some possible implementations, the tower data also includes the rotation angle of the piles; correspondingly, the tower erection point screening module 33 is specifically used to determine all tower erection conditions.

[0153] All tower erection conditions include:

[0154] The tower at the starting and ending piles of each tension section is called a tension tower; the actual rotation angle of the tension tower is equal to the rotation angle of its corresponding pile; the rotation angle of the pile is within the range of the first and second rotation angles of its corresponding tension tower.

[0155] The span between any two adjacent tower erection points is greater than the first span and less than the second span; however, if the two tower points are the starting or ending piles of the tension section, no judgment condition is required.

[0156] The difference between the distance to the ground and the elevation of the conductor connecting the small side tower at the current tower point and the current tower is greater than the safe distance to the ground; where the difference in elevation is the difference between the elevation value at the maximum sag point of the conductor and the ground elevation value at the maximum sag point.

[0157] The actual horizontal and vertical spans of the smaller side tower at the current tower erection point are less than the allowable horizontal and vertical spans of the tower. If the tower at the current tower erection point is a tension tower, the ratio of the vertical span to the horizontal span (KV value) of the tension tower is greater than the allowable KV value of the tower. If the tower is a suspension tower, it is not necessary to determine the KV value.

[0158] In some possible implementations, the tower-standing point filtering module 33 is also used to: if there is no tower-standing point on the smaller side that meets the conditions for the current tower-standing point, discard the current tower-standing point and set the next tower-standing point as the current tower-standing point.
