[0002] Currently, land for photovoltaic power plants is becoming increasingly scarce, and available land resources are becoming increasingly complex.

[0030] In related technologies, photovoltaic array arrangement methods can only arrange photovoltaic arrays oriented north-south or east-west, and cannot achieve ideal arrangement for photovoltaic arrays at tilt angles. To solve this problem, this application provides a related solution. By determining the skeleton diagram of the arrangeable area of ​​the photovoltaic array, extracting skeleton line segments from the skeleton diagram, and arranging the photovoltaic array according to the angle and direction of the skeleton line segments, the above-mentioned problem can be solved. The following is a detailed description.

[0031] According to an embodiment of this application, a method embodiment for arranging a photovoltaic array is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0032] The method embodiments provided in this application can be executed on a mobile terminal, computer terminal, or similar computing device. Figure 1 A hardware block diagram of a computer terminal (or mobile device) for implementing a photovoltaic array arrangement method is shown. Figure 1 As shown, the computer terminal 10 (or mobile device 10) may include one or more processors 102 (shown as 102a, 102b, ..., 102n in the figure) (processor 102 may include, but is not limited to, a microprocessor MCU or a programmable logic device FPGA, etc.), a memory 104 for storing data, and a transmission module 106 for communication functions. In addition, it may also include: a display, an input / output interface (I / O interface), a universal serial bus (USB) port (which may be included as one of the ports of a BUS bus), a network interface, a power supply, and / or a camera.

For example, computer terminal 10 may also include... Figure 1 The more or fewer components shown, or having the same Figure 1 The different configurations shown.

[0033] It should be noted that the aforementioned one or more processors 102 and / or other data processing circuits are generally referred to herein as "data processing circuits". These data processing circuits may be embodied, in whole or in part, in software, hardware, firmware, or any other combination thereof. Furthermore, the data processing circuits may be a single, independent processing module, or may be integrated, in whole or in part, into any other element within the computer terminal 10 (or mobile device). As involved in the embodiments of this application, the data processing circuits serve as a processor control mechanism (e.g., selection of a variable resistor termination path connected to an interface).

[0034] The memory 104 can be used to store software programs and modules for application software, such as the program instructions / data storage device corresponding to the photovoltaic array arrangement method in this embodiment. The processor 102 executes various functional applications and data processing by running the software programs and modules stored in the memory 104, thereby realizing the photovoltaic array arrangement method described above.

[0036] The display can be, for example, a touchscreen liquid crystal display (LCD) that allows the user to interact with the user interface of the computer terminal 10 (or mobile device).

[0037] Under the above operating environment, embodiments of this application provide a method for arranging a photovoltaic array, such as... Figure 2 As shown, the method includes the following steps:

[0038] Step S202: Determine the image of the target area for arranging the photovoltaic array.

[0039] According to an optional embodiment of this application, step S202 determines an image of the target area for arranging the photovoltaic array by the following method: acquiring environmental data of the site for arranging the photovoltaic array and the terrain conditions for arranging the photovoltaic array, wherein the environmental data includes at least: a redline map and elevation data; and determining an image of the target area based on the environmental data and terrain conditions.

[0040] In this step, based on the photovoltaic field area boundary map and elevation points, a three-dimensional terrain analysis and shadow analysis are performed on the land resources within the field area. Based on the terrain conditions for deploying photovoltaic arrays within the field area, suitable areas for photovoltaic array deployment are selected. For example... Figure 3 As shown.

[0041] A red line map is a site plan of a project as determined by the planning bureau, or a schematic diagram of the total land area of ​​a project as officially determined by the urban planning and management department. The red line is used to represent the outer boundary of the building, that is, the boundary of the actual usable land.

[0042] Elevation points are information points marked with elevation values, and are usually used in conjunction with contour lines to express elevation information of landform features.

[0043] Step S204: Extract the region skeleton map of the target region from the image, wherein the region skeleton map is the graphic outline of the target region represented by line segments.

[0044] During step S204, a morphological-skeleton algorithm, such as a median transformation-based algorithm, is used to extract... Figure 3 The single-pixel skeleton in the image retains basic features, and the graphic outline is represented by line segments to obtain the region skeleton map of the area where the photovoltaic array can be arranged, such as... Figure 4 As shown.

[0045] Skeleton extraction, also known as binary image thinning, is an algorithm that can thin a connected region to the width of one pixel for feature extraction and target topological representation.

[0046] Mid-axis transformation is the most common method for describing the skeleton of an object's shape; the mid-axis can be considered as precisely defining the skeleton. Commonly used mid-axis transformation methods include: topological slimming, distance transformation, and the grass-and-fire method.

[0047] Step S206: Extract multiple skeleton line segments from the regional skeleton map, and arrange the images corresponding to the photovoltaic array using the multiple skeleton line segments as axes. Each skeleton line segment includes a start point and an end point.

[0048] In this step, according to Figure 4 The shown area skeleton diagram is segmented into skeleton line segments. The photovoltaic array is arranged around the skeleton line segments as axes, and moves along the normals of the skeleton line segments to automatically achieve the arrangement of the photovoltaic array.

[0049] Step S208: Display an image of the completed photovoltaic array.

[0050] Figure 5 This is a rendering of a photovoltaic array arranged according to an embodiment of this application, such as... Figure 5 As shown, the photovoltaic array is arranged sequentially along the extracted skeleton line segments.

[0051] Through the above steps, by determining the skeleton diagram of the deployable area of ​​the photovoltaic array, extracting skeleton line segments from the skeleton diagram, and arranging the photovoltaic array according to the angle and direction of the skeleton line segments, the goal of achieving an ideal arrangement of photovoltaic arrays at tilt angles is achieved. This results in improving the design efficiency of photovoltaic array arrangement, increasing the pile foundation capacity of photovoltaic power stations, and increasing the utilization rate of land resources.

[0052] According to an optional embodiment of this application, step S206, which extracts multiple skeleton segments from a region skeleton map, includes the following steps: determining the intersection points between the segments included in the region skeleton map; determining the start and end points of each skeleton segment based on the intersection points; and connecting the start and end points of each skeleton segment to obtain multiple skeleton segments.

[0053] Figure 4The skeleton outline shown in the regional skeleton diagram consists of intersecting line segments. These segments are then divided into skeleton line segments. Specifically, morphological segmentation refers to using the intersections of line segments to decompose the regional skeleton diagram into multiple line segments connected only by a start and end point; these are the skeleton line segments.

[0054] According to another optional embodiment of this application, step S206 involves arranging the images corresponding to the photovoltaic array using multiple skeleton line segments as axes, achieved by: determining the angles of the skeleton line segments; and arranging the images corresponding to the photovoltaic array within the arrangeable range based on the angles of the skeleton line segments, wherein the arrangeable range is determined based on the regional skeleton diagram.

[0055] It is understandable that the angle of the aforementioned skeleton line segment can be interpreted as the angle between the skeleton line and the horizontal direction, or as the direction of the skeleton line segment. Arranging the photovoltaic array along the direction of the skeleton line segment allows for the arrangement of photovoltaic arrays in different directions, which can solve the technical problem of the limited arrangement methods caused by the existing technology that can only arrange photovoltaic arrays along the north-south or east-west direction.

[0056] Figure 6 This is a flowchart of a photovoltaic array arrangement method according to an embodiment of this application, such as... Figure 6 As shown, the method includes the following steps:

[0057] Step S602: Determine the data set of the photovoltaic arrays to be arranged, wherein the data set includes the length, width and quantity of each type of photovoltaic array.

[0058] Based on the types and quantities of photovoltaic arrays that can be deployed in the site, determine the data set L of photovoltaic arrays. L contains the length, width and corresponding quantity of multiple photovoltaic arrays {L1,L2,L3...}.

[0059] Step S604: Determine the image corresponding to each photovoltaic array based on the data set.

[0060] In the embodiments of this application, the image of the photovoltaic array can be determined by the length and width of the photovoltaic array, and arranging the photovoltaic array along the skeleton line segment is essentially arranging the image of the photovoltaic array.

[0061] Step S606: Determine the axial spacing between each photovoltaic array.

[0062] As an optional embodiment of this application, determining the axial spacing between each photovoltaic array includes: calculating the axial spacing between photovoltaic arrays based on the minor axis width of the photovoltaic array, the solar altitude angle at the location of the photovoltaic array, the solar azimuth angle, the slope angle of the photovoltaic array, and the azimuth angle of the photovoltaic array.

[0063] Figure 7This is a schematic diagram of the axial spacing between photovoltaic arrays according to an embodiment of this application, as shown below. Figure 7 As shown, the formula for the axial spacing D of the photovoltaic array is as follows:

[0064]

[0065] Where α is the solar altitude angle; β is the solar azimuth angle; θ is the slope angle of the photovoltaic array; γ is the azimuth angle of the photovoltaic array, and the value of γ ranges from -90° to 90°; L is the minor axis width of the photovoltaic array.

[0066] Step S608: Arrange the images corresponding to each photovoltaic array along the skeleton line segment according to the axial spacing, wherein the major axis of each photovoltaic array is parallel to the skeleton line segment, or the major axis of each photovoltaic array is at a preset angle to the skeleton line segment.

[0067] Figure 8a This is a schematic diagram of a skeleton line segment according to an embodiment of this application. Figure 8b Therefore Figure 8a The skeleton line segments shown are the baseline for arranging the photovoltaic array.

[0068] For each skeleton segment, with Figure 8a Taking the skeleton line segment as an example, photovoltaic arrays are laid out gradually from long to short within the deployable range, based on the angle of the skeleton line segment. The major axis of the photovoltaic array is at the same angle as the skeleton line segment (i.e., the major axis of the photovoltaic array is parallel to the skeleton line segment). The major axis moves along the skeleton line segment, and the minor axis moves along the normal to the major axis. The major axis of the photovoltaic array can also maintain a relatively small angle with the skeleton line segment. Based on the geometric relationship of the skeleton line segment, it is determined whether the photovoltaic array is arranged within the deployable area. When the long photovoltaic array exceeds the deployable range, a short photovoltaic array is selected from the set of photovoltaic arrays, its axial spacing D is calculated, and the photovoltaic array is arranged.

[0069] In an optional embodiment, arranging the images corresponding to the photovoltaic array within the arrangeable range according to the angle of the skeleton line segment further includes: arranging the images corresponding to each photovoltaic array sequentially along the skeleton line segment in descending order of length, according to the length of each photovoltaic array.

[0070] In the embodiments provided in this application, during the process of arranging photovoltaic arrays along the angle of the skeleton line segment, the principle is to first arrange long photovoltaic arrays, and then arrange short photovoltaic arrays when the arrangement area exceeds the arrangement range of the long photovoltaic arrays. This arrangement method allows for the arrangement of a greater number of long photovoltaic arrays within a limited area, thereby improving the utilization rate of land resources.

Based on the terrain conditions for deploying photovoltaic arrays within the field area, suitable areas for photovoltaic array deployment are selected. For example... Figure 3 As shown.

[0074] Extraction module 92 is used to extract the region skeleton map of the target region from the image, wherein the region skeleton map is the graphic outline of the target region represented by line segments.

[0075] According to an optional embodiment of this application, a morphological-skeleton algorithm, such as a median transformation algorithm, is used to extract... Figure 3 The single-pixel skeleton in the image retains basic features, and the graphic outline is represented by line segments to obtain the region skeleton map of the area where the photovoltaic array can be arranged, such as... Figure 4 As shown.

[0078] Processing module 94 extracts multiple skeleton line segments from the regional skeleton map and arranges the image corresponding to the photovoltaic array using the multiple skeleton line segments as axes. Each skeleton line segment includes a start point and an end point.

[0079] according to Figure 4 The shown area skeleton diagram is segmented to form skeleton line segments. The photovoltaic array is arranged around the skeleton line segments as axes and moved along the normals to automatically generate the array.
