in this embodiment, after the topographic information of the area to be planned is determined, an arrangeable area where the box-section road can be laid out is determined in the area to be planned based on the topographic information, wherein the arrangeable area refers to an area where the box-section road can be planned. If the slope direction is north, the slope direction is less than 30 degrees and is the arrangeable point, the slope direction is south, the slope direction is less than 20 degrees and is the arrangeable point, the slope direction is east, the slope direction is less than 35 degrees and is the arrangeable point, the slope direction is west, the slope direction is less than 35 degrees and is the arrangeable point in the area to be planned, and then all the arrangeable points can be combined into the area to obtain the arrangeable area of the arrangeable box-change road. The corresponding merge has corresponding merge rules, such as how much less than the distance to merge. Referring to fig. 5, fig. 5 is a schematic view of a scenario of an arrangeable area of a road planning method for a box transformer substation, based on the determination of topographic information, an arrangeable area composed of an undeployable area of an undeployable box transformer substation road and other grids as shown in the figure can be obtained, and then the road planning for the box transformer substation can be performed in the arrangeable area, so that the accuracy of the road planning for the box transformer substation can be ensured.

And then after the road-arrangeable point sets are determined, forming a road-arrangeable area based on the road-arrangeable point set combination density adjacent method, wherein if the point sets with the distance smaller than a certain value between the point sets are connected into one area, if the distance between the two point sets is smaller than A, the two point sets are connected into one road-arrangeable area. By mapping box-section points (to determine coordinate points) into the arrangeable area, if box-section points in the arrangeable area are not processed, the nearest arrangeable area is determined at box-section points outside the arrangeable area and mapped to the nearest arrangeable area, wherein the box-section points can also be the arrangement points of other instruments. And then, the distance matrix between the box transformer points (which can be actual box transformer points or map box transformer points) can be calculated based on the distance matrix between the determined areas, namely, the distance between the box transformer points can be determined, and then, the box transformer-road connected domain is generated based on the distance matrix between the box transformer points and the matrix between the box transformer and the main road, and then, the actual road in the station is generated based on the box transformer-road connected domain, so that the box transformer road planning in the area to be planned is realized, and the optimal scheme of the box transformer road planning is ensured to be determined.

That is, the link distance between the coordinates of each box transformer substation point is determined based on the topographic information in the arrangeable area, wherein the link distance is the link distance in the arrangeable area, and the box transformer substation point cannot pass through the non-arrangeable area, so that the accuracy of the road planning of the box transformer substation can be ensured, and meanwhile, the optimal box transformer substation planning scheme can be ensured by arranging according to the arrangeable area. The method comprises the steps that a box transformer point distance set is determined, a main road distance set is also determined at the same time, the main road distance set is constructed through terrain information in an arrangeable area, road position information of a main road and box position information, wherein the main road distance set comprises nearest connectable distance values from box transformer point coordinates to each main road in the main road position information, namely, the box transformer point distance set refers to the distance between every two box transformer point coordinates in the box transformer position information, the main road distance set refers to the nearest connectable distance values from each box transformer point coordinate to each main road, the nearest connectable distance values refer to the connecting distance from the box transformer point coordinates to the main road passing through the arrangeable area, a basis is finally provided for whether each box transformer is connected to other box transformer or the main road, and therefore the optimal planning of the box transformer road is ensured.

In this embodiment, after the box transformer point distance set and the main road distance set are determined, the box transformer roads of each box transformer point are determined based on the box transformer point distance set and the main road distance set, and then the road planning schemes of all the box transformer points are summarized to obtain all the box transformer roads of the box transformer to be laid. For example, taking the box transformer point A as an example, assuming that the closest distance between the box transformer point A and the box transformer point B in the box transformer point distance concentration is A1, the closest distance between the box transformer point A and the main road C in the main road distance concentration is A2, and then the distance value of A2 and A1 can be compared, so that the planning of the box transformer point A can be determined, and the situation that the road planning is carried out by the existing direct artificial subjective judgment is avoided. And the road planning scheme of each box transformer substation point can be determined through the box transformer substation point distance set and the main road distance set, the accuracy of box transformer substation road planning can be ensured, and the optimal planning scheme of the box transformer substation can be determined.

Further, the step of determining the box transformer road on which the box transformer is to be laid according to the box transformer point distance set and the main road distance set includes:

If the box-variable point distance set comprises box-variable point coordinates C1, C2 and C3, taking the box-variable point coordinate C1 as a point coordinate to be planned as an example, determining a distance C12 between the point coordinate C1 to be planned and the box-variable point coordinate C2 and a distance C13 between the point coordinate C1 to be planned and the box-variable point coordinate C3, and further comparing the sizes of the C12 and the C13 to serve as a first distance value, wherein the first distance value is C13; the main road distance set comprises main roads B1 and B2, further, the distance B12 between the point coordinate C1 to be planned and the main road B1 and the distance B13 between the point coordinate C1 to be planned and the main road B2 are determined, the sizes of the B12 and the B13 are compared, and the B13 with smaller value is used as a second distance value. Further, a road planning scheme of the road gauge of the point coordinate C1 to be planned can be determined by determining the magnitude relation between the second distance value B13 and the first distance value C13. The smaller value of the second distance value and the first distance value is used as a road distance value of the coordinates of the points to be planned, a target connecting line corresponding to the road distance value is determined, and finally the target connecting line determined for each coordinate of the points to be planned is used as a box transformer road of the box transformer substation to be planned.

In this embodiment, after determining the arrangeable road grids, the arrangeable road grids are combined based on a preset grid combining rule to obtain an arrangeable road grid set; the preset grid merging rule refers to merging adjacent road grids which can be arranged, and the road grid set which can be arranged refers to a grid set obtained by merging a plurality of road grids which can be arranged. When one arrangeable road grid set exists, the arrangeable road grid set is directly used as an arrangeable area of the arrangeable box-change road, otherwise, the arrangeable road grid sets are combined based on a preset grid set and rules to obtain the arrangeable area of the arrangeable box-change road; the preset grid set and the rule mean that the arrangeable road grid sets with the distance between the arrangeable road grid sets smaller than a preset distance threshold value are combined.

The actual preset distance threshold value can be set in a self-defined mode, and further a basis can be provided for actual box-type substation road planning by determining the arrangeable area.

Further, based on the first embodiment, the second embodiment and/or the third embodiment of the box-section road planning method of the present invention, a fourth embodiment of the box-section road planning method of the present invention is provided, wherein the terrain information in the arrangeable area includes a gradient value, and the step of determining a box-section point distance set from the arrangeable area according to the terrain information in the arrangeable area and the box-section position information of the box-section to be laid includes:

The gradient values in the subarea area are not greatly different, so that the actual gradient values are not greatly different from the two-dimensional calculation. After the determination of the sub-area, a value of the connectable distance to other box-section point coordinates is determined for each box-section point coordinate as a first point coordinate based on the sub-area, wherein the other box-section point coordinates refer to box-section point coordinates other than the first point coordinate. That is, based on the zone areas, the length through each zone and the height difference between the two zones are determined, and thus the distance value can be determined. And further, the accuracy of road distance determination and calculation efficiency can be ensured through gradient partition.

Further, the box-section position information includes box-section mounting point coordinates, and the step of determining box-section point coordinates from the arrangeable area according to the arrangeable area and the box-section position information of the box section to be laid includes:

step S3131 of taking the box-section mounting point coordinates as box-section point coordinates in the case where the box-section mounting point coordinates are in the arrangeable area;

step S3132, in the case where the box-section installation point coordinates are outside the arrangeable area, determining a nearest area coordinate point of the box-section installation point coordinates, and taking the nearest area coordinate point as box-section point coordinates; wherein the nearest region coordinate point includes coordinates in the arrangeable region nearest to the box-section mounting point coordinates.

In the present embodiment, in determining the road planning scheme of each box-section coordinate, by detecting whether the box-section mounting point coordinate is in the arrangeable area, when in the arrangeable area, the box-section mounting point coordinate is determined as the box-section point coordinate; if the box-type variable-point coordinate system is not in the arrangeable area, determining a nearest area coordinate point of the box-type variable-point coordinate system, and taking the nearest area coordinate point as the box-type variable-point coordinate system; wherein the nearest region coordinate point includes coordinates in the arrangeable region nearest to the box-section mounting point coordinates. The box transformer substation installation point coordinates refer to installation coordinates of box transformer substation points, and can be moved to nearest region coordinate points at the moment, or calculated only by nearest region coordinate points, and the actual box transformer substation installation point coordinates are unchanged. That is, referring to fig. 5, taking the box-section mounting point coordinate F as an example, if the point F may be a white non-arrangeable area, the box-section point coordinate is obtained by moving it out of the white non-arrangeable area. When the box transformer substation installation point coordinates are in the arrangeable area, the coordinates are unchanged and are [ x, y, z ]; if the box transformer substation installation point coordinates are in the undeployable area, finding out the coordinate point of the nearest area in the undeployable area from the box transformer substation installation point coordinates, forcing the box transformer substation point coordinates to be [ xr, yr, zr ], further guaranteeing the accuracy of subsequent planning and the use effect of devices, providing planning basis for subsequent box transformer substation road planning, and guaranteeing the planning accuracy.

Further, based on the first embodiment, the second embodiment, the third embodiment and/or the fourth embodiment of the box-section road planning method of the present invention, a fifth embodiment of the box-section road planning method of the present invention is provided, and the step of determining, based on the partition area, a value of a connectable distance with other box-section point coordinates as a first point coordinate for each box-section point coordinate includes:

step l, determining connection line information between each box transformer point coordinate and other box transformer point coordinates as a first starting point coordinate based on the partition area; the connection information refers to information of linear connection between two points;

m, if the connection information is matched with a preset connection-enabled condition, sequentially determining the partition area through which the connection information passes as a target partition area; the preset connectable condition refers to that straight lines connected in a straight line completely pass through the subarea area;

in this embodiment, after determining the partition area, the connection information between each box-section point coordinate and other box-section point coordinates is further determined as the first point coordinate, where the connection information refers to the information of the straight line connection between the two points. I.e., the distance of each bin-change point coordinate to the other bin-change point coordinates is determined based on the following manner. Taking the box-change point coordinate XB1 and the box-change point coordinate XB2 as examples, determining connection information between other box-change point coordinates by taking the box-change point coordinate XB1 as a first start point coordinate, if the other box-change point coordinate is the box-change point coordinate XB2, determining whether the connection information of the box-change point coordinate XB1 and the box-change point coordinate XB2 is matched with a preset connectable condition, and when the connection information is matched, sequentially determining a partition area through which the connection information passes as a target partition area. The preset connectable line condition means that a straight line connected with the straight line passes through the partition area, that is, the box-change point coordinate XB1 and the box-change point coordinate XB2 can be connected with the straight line and do not pass through the inexorable area, the distance connected with the straight line can be directly calculated, the target partition area means that the straight line passes through the partition area, for example, the straight line connected with the box-change point coordinate XB1 and the box-change point coordinate XB2 passes through the road partition areas 1 and 2, and the distance can be calculated based on the partition areas 1 and 2.

By way of example, a user may select a region with a smaller gradient to perform road planning for the box transformer substation according to the requirement, rather than pursuing the nearest road, so that the selectivity of road planning for the box transformer substation may be improved. I.e., the optimizing manner, as described in determining the bin variable point coordinates XB1 to the bin variable point coordinates XB2, the bin variable point coordinates XB1 are put into the list 1. Table 1 functions to store adjacent partitioned areas of box-section point coordinates XB1 (partitioned areas adjacent to the partitioned area where box-section point coordinates XB1 are located). Further, in table 1 of box transformer point coordinates XB1, a partition area P1 satisfying the requirement (box transformer point coordinates XB1 to box transformer point coordinates XB2 are minimum estimated distances) is determined, and further, box transformer point coordinates XB1 are updated to the center coordinates of partition area P1, and the step of determining table 1 is continued. Finally, until the partition area P1 contains the partition area where the box-change point coordinate XB2 is located, taking the previous path as the box-change point coordinate XB1 to the box-change point coordinate XB2, and the minimum estimated distance (distance cost function) is as follows:

the distance cost function R (n) from the bin variable point coordinate XB1 and the center coordinate of each adjacent partitioned area and the bin variable point coordinate XB1 is calculated as: r (n) =k (n) +b (n);

Where K (n) represents the distance from the box-section point coordinate XB1 to the center coordinate of the adjacent partitioned area, and B (n) represents the estimated distance (non-actual distance) from the center coordinate of the adjacent partitioned area to the box-section point coordinate XB2, and its corresponding calculation formula is as follows:

K(n)＝Sqrt((Xm-Xn)^2+(Ym-Yn)^2+(Zm-Zn)^2)；

B(n)＝Sqrt((Xn-Xf)^2+(Yn-Yf)^2+(Zn-Zf)^2)；

wherein, xm, ym, zm are three-dimensional coordinates of box-change point coordinate XB1, xf, yf, zf are three-dimensional coordinates of box-change point coordinate XB2, xn, yn, zn are three-dimensional coordinates of center coordinates of adjacent partitioned areas, and the mode of finding the distance may be manhattan, euro, chebyshev, and the mode of angle cosine, which is not limited herein. And further, the optimal searching of the road planning of the box transformer substation can be ensured, and the accuracy of the road planning of the box transformer substation is improved. The connection mode can be based on the connection mode, so that the connection selectivity can be ensured.

Step n, determining a two-dimensional distance value of the connection information in the target partition area, and determining a height difference value between the target partition area and a next target partition area based on the gradient value;

step o, sequentially determining three-dimensional distance values of the height difference value and the two-dimensional distance value based on the connection information, and taking the sum of the three-dimensional distance values as a connectable distance value; wherein the three-dimensional distance value refers to a value of a power of half of a sum of squares of the height difference value and the two-dimensional distance value;

Step p, if the connection information is not matched with the preset connection-enabled condition, updating the connection information based on a preset connection mode, and executing the step of sequentially determining the partition area through which the connection information passes as a target partition area; the preset connection mode refers to a connection mode based on characteristic points on boundary lines of the partition area.

In this embodiment, when the connection is a straight line connection, after determining the partition area, the two-dimensional distance value of the connection information in the target partition area is used to determine the height difference between the target partition area and the next target partition area based on the gradient value. Wherein, the two-dimensional distance value refers to the two-dimensional connecting line distance. If the connecting straight line of the box-change point coordinate XB1 and the box-change point coordinate XB2 passes through the subarea areas 1 and 2, the box-change point coordinate XB1 is in the subarea area 1, the box-change point coordinate XB2 is in the subarea area 2, the two-dimensional distance from the box-change point coordinate XB1 to the boundary point of the subarea area 1 is further determined, the boundary point refers to the point where the straight line passes through the boundary line of the subarea area 1, the height difference value of the subarea areas 1 and 2 is determined, the subarea area 2 is the next target subarea area of the box-change road subarea area 1, and the distance between the box-change point coordinate XB1 and the box-change point coordinate XB2 can be calculated at the moment. Referring to fig. 6, fig. 6 is a schematic diagram of a scenario of distance calculation of a road planning method for a box transformer substation, and assuming that two squares of a right image are a subarea area and a road route is finally determined to be required to pass through the subarea area, the distance calculation between the subarea areas of the road transformer substation is as shown in the following formula 3:

Wherein: Δl is the linear distance in the subarea, i.e. the two-dimensional distance, Δh is the elevation difference between adjacent subareas, and the elevation difference must be calculated between every two, and cannot be finally calculated directly. Based on the previous elevation difference formula, the gradient of the regional area of the road of the box transformer substation is approximately not different, so that the distance calculation value of a single regional area which can be arranged is more accurate, and the k value of the subsequent wiring can be set more accurately based on the fact that the gradient value is not different, if the elevation difference of the regional area is H1, the k value corresponding to the regional area is k1. When the connection information is not matched with the preset connection-possible condition, updating the connection information based on a preset connection mode, and executing the step of sequentially determining the arrangeable partition area through which the connection information passes as a target partition area; the preset connection mode is a connection mode based on characteristic points on boundary lines of the partition areas, that is, if a straight line in the first connection information passes through the non-arrangeable area, it is determined that the straight line in the first connection information passes through characteristic points of the non-arrangeable area (that is, points where the straight line is connected in the non-arrangeable area), and then an optimal connection scheme is determined between the characteristic points. At this time, there are two schemes, one is to directly use the above optimizing method to directly optimize the feature points to determine the optimal connection scheme, and the other is to perform the linear connection between the feature points on the boundary line between the determined non-arrangeable area and the arrangeable area, so as to determine the distance between the two points. If the non-arrangeable area is a regular square, it is possible to determine a boundary line extending the regular square for planning a road, and then determine a box-section road plan passing through the non-arrangeable area based on the above. It should be noted that the basic principle of the above planning method is to directly connect with the end point straight line after bypassing the non-arrangeable area, or directly use the above optimizing scheme.

By way of example, the value of the connectable line distance can be determined from the first setpoint coordinate to the respective other bin change point coordinate distance value, and a set or matrix can be established on the basis of the respective connectable line distance value. Finally, the distance between each box-section point coordinate and other box-section point coordinates is determined in the above manner. The distance matrix between the required bin change point coordinates can be obtained, wherein the distance matrix is as follows:

the distance between the box transformer point coordinates is obtained, so that the box transformer point coordinates and the planning basis after the box transformer point coordinates can be determined based on the distance between the box transformer point coordinates, the accuracy of box transformer road planning in the area to be planned is ensured, and the determined planning scheme is ensured to be optimal. Meanwhile, the design of the follow-up medium-voltage cable can be facilitated based on the partition, and the accuracy of the cable design is guaranteed.

Further, the main road position information includes a road coordinate point of each main road of the area to be planned, and the step of constructing a main road distance set according to the topographic information in the arrangeable area, the road position information of the main road, and the box position information includes:

step q of determining a minimum link distance value with a road coordinate point of each main road for each box-change point coordinate as a second start point coordinate based on the partitioned area determined by the topographic information in the arrangeable area;

R, constructing a main road distance set according to a minimum connecting line distance value determined by each second starting point coordinate and starting point coordinates of a connectable line segment of the minimum connecting line distance value; the starting point coordinates comprise starting point coordinates and end point coordinates of the connectable line segments.

In this embodiment, the steps of determining the main road distance set are similar to the steps of determining the distances between the case change point coordinates, and there is a difference in that the former is the distance between the determination point and the point, and here the distance between the determination point and the line, if the line is a straight line, the vertical distance can be directly determined, since the main road position information includes the road coordinate point of each main road of the area to be planned, that is, the line needs to be selected, the road coordinate point refers to the feature coordinate point of each main road with respect to each case change point coordinate, if the main road is circular, the four feature coordinate points of the main road are determined at least as the road coordinate points, and then the partition area determined based on the topographic information in the arrangeable area is further determined for each case change point coordinate as the second start point coordinate, and the minimum link distance value between the partition area determined based on the topographic information in the arrangeable area is the same as the previous step, and the minimum link distance value refers to the shortest distance from the second start point coordinate to the road coordinate point of each main road. If the main road Q has road coordinate points Q1, Q1 and Q3 for the second starting point coordinate C1, further determining a distance Q11 from the second starting point coordinate C1 to the road coordinate point Q1, a distance Q21 from the second starting point coordinate C1 to the road coordinate point Q2, and a distance Q31 from the second starting point coordinate C1 to the road coordinate point Q3, further determining the minimum value among Q11, Q21 and Q31 as a road planning scheme from the second starting point coordinate C1 to the main road Q. And then a main road distance set can be constructed according to the minimum connecting line distance value and the starting point coordinates of the connectable line segments of the minimum connecting line distance value determined by each second starting point coordinate, wherein the starting point coordinates comprise the starting point coordinates and the end point coordinates of the connectable line segments, namely, the distance from each box transformer point coordinate to each main road can be determined in the determining mode, so that a basis is provided for the subsequent box transformer road planning, planning is carried out on the basis of the topographic information in the arrangeable area, the determined connecting line is guaranteed to be optimal, and the optimal of the final box transformer road planning can be determined.
