Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of computer information processing, in particular to a cable support information determination method, device and equipment. BACKGROUND

[0002] In power transmission and transformation projects, high-voltage cables and their supports play a crucial role, and they are widely used in design schemes, construction schemes and other aspects. Currently, the establishment of high-voltage cable support models mainly relies on manual operation. Specifically, the support model needs to be assembled manually, and standard models are called one by one to arrange high-voltage cable fittings, upper channel steels, lower angle steels (channel steels) and other components. For the height adjustment of the intermediate adjustable channel steel, the parameters need to be manually modified to adapt to the height difference between the high-voltage cable and the ground. In terms of spatial angle processing, for a large number of support positions with angles, the established support model can only be rotated manually, and the support angle and the high-voltage cable angle are difficult to form a perpendicular relationship. When determining the necessary support positions, they can only be arranged one by one after artificial judgment. For a longer high-voltage cable path, since batch generation is not possible, the support can only be roughly determined in a single plan view to arrange the support. This traditional establishment method is low in efficiency, difficult to guarantee accuracy, and difficult to meet complex engineering requirements. SUMMARY

[0050] In an optional embodiment of the application, step 11 can include:

[0051] Step 111, sweeping the cable to obtain a cable laying path curve:

[0052] f(t)=a0+a1t+a2t 2 +…a n t n ;

[0053] Wherein, f(t) is the cable laying path curve, t is the parameter, a n is the coefficient of the curve.

[0054] In the embodiment, the high-voltage cable that has completed the layout is reversely swept to generate the cable laying path curve.

[0055] Specifically, according to the high-voltage cable that has completed the layout, a high-voltage cable model is generated, point cloud data of the high-voltage cable is collected through the high-voltage cable model, the collected point cloud data is cleaned and processed, including removing noise, filling missing parts and smoothing, and key features such as straight line segments, curves, planes or complex surfaces are identified in the point cloud data; based on the key features, a path curve is selected, and the starting point, the end point, the sweeping direction, and the shape and size of the sweeping section are determined along the path curve to form a three-dimensional entity model, the center axis of the three-dimensional entity model is taken as the cable laying path curve, and the function is represented as:

[0056] f(t) = a0 + a1t + a2t 2 +…a n t n ;

[0057] Wherein, f(t) is the cable laying path curve, t is parameter, a n is the coefficient of the curve, n is the number of the cable laying path curve function. By changing the value of t, the coordinates of different positions can be obtained.

[0058] As Figure 2 shown in an optional embodiment of the present application, step 12 can include:

[0059] Step 121, on the cable laying path curve, generate reference points with a preset interval and parameter t.

[0060] In this embodiment, read the cable laying path curve and set a preset fixed interval d. Analyze the cable laying path curve function f(t) = a0 + a1t + a2t 2 +…a n t n , starting from the starting position of the curve, calculate a series of t values according to t i = ixd (where i is an integer, representing an integer index), substitute these t values into the path curve function f(t) to obtain the corresponding coordinate points, generate reference points with an interval on these coordinate points, and record their coordinates (x i , y i , z i ). When it is judged that the loop calculation reaches the end position of the curve, the calculation is ended, and the positions of all reference points are determined.

[0061] In a specific embodiment, the preset fixed interval is d = 400 mm, and the path curve function is assumed to be f(t) = t 2 + 2t + 1.

[0062] When i = 0, t0 = 0, the reference point coordinates (1.2345, 2.3456, 3.4567) can be obtained;

[0063] When i = 1, t1 = 400, the reference point coordinates (160161.2345, 802.3456, 3.4567) can be obtained;

[0064] When i = 2, t1 = 800, the reference point coordinates (640801.2345, 1602.3456, 3.4567) can be obtained.

[0065] In an optional embodiment of the present application, step 13 can include:

[0066] The cable parameter data information includes cable diameter information, cable fixed height information and ground height information.

[0067] The cable support parameter data includes top fixed beam parameter, bottom fixed beam parameter, middle adjustable support column length and cable support fitting parameter.

[0068] In step 131, the inner diameter of the cable support fitting and the outer diameter of the cable support fitting are determined according to the cable diameter information.

[0069] In step 132, the length of the middle adjustable support column of the cable support is determined according to the cable fixed height information.

[0070] In this embodiment, the cable support fitting is composed of multiple circular rings, which is used to set on the outside of the cable to fix the cable. The cable support fitting needs to be pre-set with a certain allowance to ensure that the cable can pass through smoothly without being squeezed.

[0071] Therefore, the inner diameter of the cable support fitting is determined according to the cable diameter:

[0072] And the outer diameter of the cable support fitting is determined according to the inner diameter of the cable support fitting: R out = R in + 200mm, where D cable represents the high-voltage cable diameter, R in represents the inner radius of the high-voltage cable fitting, and R out represents the outer radius of the high-voltage cable fitting.

[0073] In a specific embodiment, the high-voltage cable diameter D cable = 130mm, then the inner radius The outer radius R out = 165+200=365mm.

[0074] Further, according to the cable fixed height and the distance between the cable and the ground, the length of the middle adjustable support column of the cable support is obtained, and then the total height of the cable support is determined.

[0075] In an optional embodiment of the present application, step 132 can include:

[0076] The cable support includes a top fixed beam, a bottom fixed beam, a middle adjustable support column and a cable support fitting, the top fixed beam and the bottom fixed beam are fixedly connected through the middle adjustable support column, and the cable support fitting is fixedly connected with the top fixed beam.

[0077] According to the cable fixing height information, the ground height information, the parameter information of the top fixing beam and the parameter information of the bottom fixing beam, the length of the middle adjustable support column of the cable support is determined.

[0078] In this embodiment, a type library of the cable support is established, and the type library is provided with parameterized models of various support types, including single-column support, double-column support, three-column support and the like. Different support types can be selected according to the number of cables, the density and the like of different use scenarios. For example, when the number of cables is small and the cables are densely arranged, a single-column support is used; when the number of cables is large and the cables are sparsely arranged, a double-column support is used and the like.

[0079] A spatial three-dimensional coordinate system X-Y-Z is established, and the X axis represents the length, the Y axis represents the thickness and the Z axis represents the width.

[0080] As shown in Figure 3 , the single-column support is composed of a top fixing beam, a bottom fixing beam, a middle adjustable support column and a set of cable support fittings. The length of the top fixing beam is greater than that of the bottom fixing beam. According to the required support height of the support, a middle adjustable support column with different length is selected. The cable support fittings include three rings with the same diameter. Specifically, the top fixing beam is an upper end channel steel, the bottom fixing beam is a lower end angle steel and the middle adjustable support column is a middle channel steel. When assembled, one end of the middle channel steel is welded in the groove of the upper end channel steel, and the other end is welded in the groove of the lower end angle steel.

[0081] The upper end channel steel and the lower end angle steel are fixed in size, so the length of the middle channel steel only needs to be determined, and the size of each structure of the single-column support can be determined. The length of the middle channel steel is calculated by the following formula:

[0082] R cable =D cable ÷2;

[0083] H stand =Z rp -H ground -R cable ;

[0084] L mc =H stand -T uc -T da ;

[0085] Wherein, Z rp represents the Z coordinate of the reference point, L uc represents the length of the upper end channel steel, W uc represents the width of the upper end channel steel, T uc represents the thickness of the upper end channel steel of the single-column support, L da represents the side length of the lower end angle steel of the single-column support, and T daH represents the thickness of the lower end angle steel of the single-column support stand L represents the total height of the single-column support mc D represents the length of the middle channel steel of the single-column support cable R is the diameter of the cable calbe H is the radius of the cable ground H is the ground elevation.

[0086] As shown in Figure 4 , the double-column support is composed of a top fixed beam, a bottom fixed beam, two middle adjustable support columns and a set of cable support fittings. The length of the top fixed beam is less than that of the bottom fixed beam. Different lengths of middle adjustable support columns are selected according to the required support height of the support. The cable support fittings include three circular rings with the same diameter. Specifically, the top fixed beam uses an upper end channel steel, the bottom fixed beam uses a lower end channel steel, and the middle adjustable support column uses two middle channel steels. When assembling, one end of the middle channel steel is welded to the surface of the upper end channel steel, and the other end is welded to the surface of the lower end angle steel.

[0087] The upper end channel steel and the lower end angle steel are fixed sizes, so only the length of the middle channel steel needs to be determined to determine the size of each structure of the double-column support. The length of the middle channel steel is calculated by the following formula:

[0088] R cable =D cable ÷2;

[0089] H dual =Z rp -H ground -R cable ;

[0090] L mc2 =H dual -W uc2 -W dc ;

[0091] Wherein, Z rp represents the Z coordinate of the reference point, L uc2 represents the length of the upper end channel steel of the double-column support, W uc2 represents the width of the upper end channel steel of the double-column support, T uc2 represents the thickness of the upper end channel steel of the double-column support, L dc represents the length of the lower end channel steel of the double-column support, W dc represents the width of the lower end channel steel of the double-column support, T dc represents the thickness of the lower end channel steel of the double-column support, H dual represents the total height of the double-column support, L mc2 represents the length of the middle channel steel of the double-column support, D cable R is the diameter of the cable cable H is the radius of the cable groundThe ground elevation is determined.

[0092] Further, the parameters of the cable support fittings are determined:

[0093] The cable support fittings are composed of a circular ring, which is used to set the cable, so the cable support fittings need to be slightly larger than the diameter of the cable.

[0094] Set the inner radius The outer radius R out = R in + 200 mm.

[0095] Where D cable represents the diameter of the cable, R in represents the inner radius of the cable fitting, and R out represents the outer radius of the cable fitting.

[0096] In a specific embodiment, the parameters of the single-column support are determined:

[0097] The upper end channel steel length is L uc = 1200 mm, the width is W uc = 80 mm, and the thickness is T uc = 15 mm; the lower end angle steel side length is L da = 80 mm, and the thickness is T da = 20 mm.

[0098] Obtain the engineering condition parameters, including:

[0099] Reference point coordinates (1.2345, 2.3456, 3.0000), reference point height Z rp = 3 m = 3000 mm, that is, the cable fixing height at this reference point is 3000 mm; high-voltage cable diameter D cable = 130 mm, radius

[0100] The ground elevation of this reference point is 500 mm, so

[0101] H stand = 3000 mm - 500 mm - 65 mm = 2435 mm,

[0102] L mc = 2435 - 15 - 20 = 2400 mm,

[0103] The length of the middle channel steel is calculated to be 2400 mm.

[0104] The parameters of the double-column support are determined:

[0105] The upper end channel steel length is L uc2 = 1500 mm, the width is W uc2= 100 mm, thickness T uc2 = 20 mm; lower end channel steel length L dc = 1500 mm, width W dc = 100 mm, thickness T dc = 20 mm.

[0106] Obtain the engineering condition parameters, including:

[0107] Reference point coordinates (1.2345, 2.3456, 3.0000), i.e. reference point height Z rp = 3 m = 3000 mm; i.e. the cable fixing height at this reference point is 3000 mm; high voltage cable diameter D cable = 130 mm, radius

[0108] The ground elevation of this reference point is 500 mm, so

[0109] H dual = 3000 mm-500 mm-65 mm = 2435 mm;

[0110] L mc2 = 2435-100-100 = 2235 mm;

[0111] The length of the middle channel steel is calculated to be 2235 mm.

[0112] Determination of the parameters of the cable support fittings:

[0113] High voltage cable diameter D cable = 130 mm, so the inner radius Outer radius R out = 165 + 200 = 365 mm.

[0114] Through the type library of the cable support, the type and size of the cable support can be quickly determined according to the coordinate information of the reference point, and the length, thickness, and width of each structure of the cable support are specified according to the spatial three-dimensional coordinate system of the type library, so that the fixed beam, support column, cable support fittings, and other structures that meet the requirements can be generated.

[0115] In an optional embodiment of the present application, step 14 can include:

[0116] Step 141, determining the structure of the cable support according to the inner diameter of the cable support fitting, the outer diameter of the cable support fitting, the top fixed beam, the bottom fixed beam, and the middle adjustable support column;

[0117] Step 142, arranging the cable support with the determined structure according to the preset arrangement rule to obtain the arrangement position information of the cable support.

[0118] In this embodiment, the inner diameter of the cable support fittings, the outer diameter of the cable support fittings, the top fixed beam, the bottom fixed beam, and the middle adjustable support column of the cable support fittings at each reference point determined by step 13 determine the structure of the cable support arranged at each reference point (such as single-column support or double-column support).

[0119] The cable support arrangement position rule is set: when the arc between the adjacent three reference points is less than the preset arc threshold, the reference point at the middle position is determined as a necessary fixed point, the cable support is arranged at the necessary fixed point position, and the cable supports are arranged at equal intervals between the necessary fixed points.

[0120] In an optional embodiment of the present application, step 142 can include:

[0121] Step 1421, determining the fixed points of the cable support according to the arc between the plurality of reference points;

[0122] Step 1422, determining the working plane according to the normal plane of the fixed points of the cable support, and arranging the cable support in the working plane.

[0123] In this embodiment, the cable diameter D cable = 130 mm and the set turning radius coefficient k = 1.2.

[0124] The arc θ between the consecutive three reference points P1, P2, P3 is calculated:

[0125] P1(x1, y1, z1) = (500.12345, 300.23456, 100.34567);

[0126] P2(x2, y2, z2) = (600.12345, 400.23456, 200.34567);

[0127] P3(x3, y3, z3) = (700.12345, 500.23456, 300.34567);

[0128] The arc θ value is obtained by the formula

[0129] When θ < E = 0.4 radian, the middle reference point P2 is determined as a necessary fixed point, and a cable support is arranged at the necessary fixed point position, as shown in Figure 5 The B area in the figure is the necessary fixed point.

[0130] As shown in Figure 5 ​As shown, in the A region, when the Z coordinate of the reference point changes, that is, |Z2-Z1|>600mm, the starting point reference point and the end point reference point of the change are determined as the necessary fixed points, and a cable support is arranged at the position of the necessary fixed point;

[0131] When the reference point distance from the ground height information h>5000mm, no cable support is needed, and no fixed point is set.

[0132] After the necessary fixed points are determined, the cable supports are evenly generated between the necessary fixed points, and the rules are as follows:

[0133] Calculate the distance between the necessary fixed points with the existing cable support coordinates:

[0134]

[0135] Then, according to the preset interval F, the support positions are evenly distributed between the two necessary fixed points, and according to the distance of the current fixed point from the ground height information, it is determined whether the ground support needs to be referenced, and the length of the middle adjustable support column is adjusted.

[0136] Wherein, x a ,y a ,z a and x b ,y b ,z b represent the coordinates of the two existing support coordinate reference points, d ref represents the distance between the two reference points, and F represents the preset interval.

[0137] Based on the coordinates of the fixed points (x i ,y i ,z i ), the normal vector of the cable at the point is obtained:

[0138]

[0139] According to the normal vector, the working plane is determined, and the equation of the working plane can be expressed as:

[0140] n x (x-x r )+n y (y-y r )+n z (z-z r )=0;

[0141] Further, each cable support generated is arranged in the working plane of the corresponding fixed point.

[0142] In a specific embodiment, the coordinates of the two necessary fixed points are:

[0143] A(x a ,y a ,z a = (800.12345, 600.23456, 200.34567)

[0144] B(x b ,y b ,z b If ) = (1200.12345, 900.23456, 300.34567), then we have

[0145]

[0146] Cable supports are evenly distributed between two reference points at a preset spacing of F = 2000 mm.

[0147] The current measured distance between the fixed point and the ground is h. ref =400mm, ground elevation is 500mm, due to h ref For cables less than 500mm, ground supports are required, and the adjustable channel steel in the middle should be adjusted as needed to ensure that the cable installation height is above the ground.

[0148] In addition to automatic cable routing, cable supports can also be manually routed, as detailed below:

[0149] The coordinates of the randomly selected reference point are (1500.12345, 800.23456, 400.34567), and the selected support type is: generate single column support.

[0150] Based on the selection, a single-column support model was successfully generated at the reference point. The upper channel steel has a length of 1200mm, a width of 80mm, and a thickness of 15mm; the lower angle steel has a side length of 80mm and a thickness of 8mm; and the middle adjustable channel steel has a length of 220mm.

[0151] The cable support information determination method in the above embodiments of the present application can automatically extract cable information, quickly and accurately obtain required data, avoid errors and omissions that may occur during manual collection, greatly improve work efficiency and data reliability, establish a rich and comprehensive high-voltage cable support type library that covers various specifications and parameters, meet various complex and special requirements in power transmission and transformation projects, provide more options and flexibility for designers, automatically generate high-voltage cable supports, ensure that the generated supports meet design requirements through accurate algorithms and preset parameters, avoid uncertainties and errors caused by manual operation, and significantly improve the quality and stability of the supports, formulate cable support arrangement rules, accurately generate batches for both regular arrangements and long cable paths, greatly improve the overall efficiency and quality of engineering design, and effectively meet the high standards of precision and efficiency required by complex projects. It has important practical significance for improving the design quality of power transmission and transformation projects, shortening the construction period, reducing costs, and ensuring the safe and reliable operation of projects.
