[0059] The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.
[0060] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0061] The envelope generation method, envelope generation device, electronic device, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.
[0062] The envelope generation method can be applied to a terminal, specifically executed by the hardware or software within the terminal.
[0063] The terminal includes, but is not limited to, portable communication devices such as mobile phones or tablets with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads). It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer with touch-sensitive surfaces (e.g., touchscreen displays and / or touchpads).
[0064] The following embodiments describe a terminal including a display and a touch-sensitive surface. However, it should be understood that the terminal may include one or more other physical user interface devices such as a physical keyboard, mouse, and joystick.
[0065] The envelope generation method provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can implement the envelope generation method. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, cameras, and wearable devices. The envelope generation method provided in this application embodiment is described below using an electronic device as the execution subject.
[0066] like Figure 1 As shown, the envelope generation method includes steps 110 to 140.
[0067] Step 110: Obtain the array position information of multiple photovoltaic arrays in the photovoltaic array.
[0068] Among them, array position information is used to characterize information such as the arrangement and size of the photovoltaic array.
[0069] In this embodiment, the array position information can include coordinate information, length information and width information of each photovoltaic array in the plurality of groups of photovoltaic arrays.
[0070] It can be understood that one photovoltaic array includes a plurality of groups of photovoltaic arrays, each group of photovoltaic arrays has corresponding position information and size information, and the array position information of the photovoltaic array is a collection of the position information and size information of each group of photovoltaic arrays.
[0071] In actual implementation, the photovoltaic array can be built according to the array position information, and the array position information of the plurality of groups of photovoltaic arrays of the photovoltaic array can be obtained according to the information related to the building of the photovoltaic array.
[0072] Step 120, determining the array connection relationship of the plurality of groups of photovoltaic arrays based on the array position information.
[0073] It should be noted that the array connection relationship refers to the relationship between the photovoltaic arrays whether to be connected in the process of generating the envelope line.
[0074] In this embodiment, the array connection relationship between two photovoltaic arrays, in the process of generating the envelope line, the two photovoltaic arrays need to be connected.
[0075] It can be understood that two photovoltaic arrays without the array connection relationship do not need to be connected in the process of generating the envelope line.
[0076] In this embodiment, the array connection relationship of the plurality of groups of photovoltaic arrays in the photovoltaic array is determined according to the photovoltaic array arrangement in the photovoltaic array represented by the array position information, and whether the photovoltaic array needs to be connected in the process of generating the envelope line is determined on the basis of the photovoltaic array arrangement, and the two photovoltaic arrays that need to be connected belong to the same photovoltaic array.
[0077] Step 130, connecting the plurality of groups of photovoltaic arrays based on the array connection relationship to generate a global closed area of the photovoltaic array.
[0078] In this embodiment, the global closed area of the photovoltaic array refers to a closed polygonal area obtained by connecting the plurality of groups of photovoltaic arrays of the photovoltaic array according to the array connection relationship.
[0079] In this step, the global closed area of the photovoltaic array can be obtained by connecting all the groups of photovoltaic arrays with the array connection relationship in the photovoltaic array, and the global closed area of the photovoltaic array covers all the photovoltaic arrays belonging to the photovoltaic array.
[0080] Step 140, generating an envelope line of the photovoltaic array based on the global closed area.
[0081] In this embodiment, the global closed region of the photovoltaic array covers all photovoltaic arrays belonging to the photovoltaic array, and according to the global closed region of the photovoltaic array, a clear boundary of the photovoltaic array, i.e., the envelope line of the photovoltaic array, can be obtained according to the global closed region.
[0082] According to the envelope line generation method provided in the embodiments of the present application, the array connection relationship between the photovoltaic arrays is determined through the array position information of the photovoltaic arrays in the photovoltaic array, the photovoltaic arrays are connected, the global closed region corresponding to the photovoltaic array is obtained, and the envelope line of the photovoltaic array is determined. The envelope line calculation is accurate and has strong adaptability, which can adapt to any scene without the need for additional setting of other input parameters. The method modeling is simple and has high calculation efficiency.
[0083] In some embodiments, step 120 can include determining, based on the array position information, array adjacent relationships of the photovoltaic arrays in the multiple groups of photovoltaic arrays.
[0084] Based on the array adjacent relationships, the array connection relationship is determined.
[0085] In this embodiment, according to the array position information representing the arrangement of the photovoltaic arrays, the array adjacent relationships between the photovoltaic arrays in the photovoltaic array can be determined, i.e., whether two photovoltaic arrays are adjacent is determined according to the arrangement of the photovoltaic arrays.
[0086] Based on the array position information, the array adjacent relationship of whether the photovoltaic arrays are adjacent is determined, and then the array connection relationship of whether the photovoltaic arrays are connected is obtained.
[0087] In some embodiments, the array position information includes coordinate information, length information and width information of the photovoltaic arrays in the multiple groups of photovoltaic arrays, and based on the array position information, the array adjacent relationships of the photovoltaic arrays in the multiple groups of photovoltaic arrays can include:
[0088] Based on the coordinate information and the width information of the photovoltaic arrays in the multiple groups of photovoltaic arrays, the multiple groups of photovoltaic arrays are divided into multiple rows of photovoltaic arrays distributed along a first direction, and the first direction is the width direction of the photovoltaic arrays.
[0089] Based on the length information, the array adjacent relationships of the photovoltaic arrays in the same row of photovoltaic arrays are determined.
[0090] Based on the coordinate information, the array adjacent relationships of the photovoltaic arrays in adjacent rows of photovoltaic arrays are determined.
[0091] The adjacent rows of photovoltaic arrays are determined based on a target row spacing, and the target row spacing is determined based on the array position information.
[0092] In actual execution, the first direction is the width direction of the photovoltaic arrays, and the first direction can be the Y direction of the coordinate information of the photovoltaic arrays.
[0093] Based on the coordinate and width information of each photovoltaic array, multiple photovoltaic arrays are divided into multiple rows. The photovoltaic array can be divided into rows according to the Y-coordinate of the center point of each photovoltaic array. The difference in the Y-coordinate of two photovoltaic arrays can be divided into a row if the width of one photovoltaic array is one row.
[0094] It is understandable that the length and width of the photovoltaic array in a photovoltaic array can be uniform, that is, different photovoltaic arrays have the same length or width.
[0095] If the distance between adjacent edges of two photovoltaic arrays in the same row is within the length of one photovoltaic array, it proves that the two photovoltaic arrays are adjacent and have an array adjacency relationship.
[0096] Based on the array position information, the target row spacing is calculated. For a photovoltaic array row, if the difference in the Y-direction coordinate between two photovoltaic array rows is within the range of the target row spacing, they can be defined as adjacent rows, i.e., adjacent photovoltaic array rows.
[0097] For example, based on the array position information, the mode d1 or the average d2 of the front and rear row spacing between photovoltaic arrays is calculated, and the target row spacing for dividing adjacent rows is determined to be 1.5d1 or 1.5d2.
[0098] For photovoltaic arrays in adjacent rows, if two photovoltaic arrays intersect in the X direction, it proves that the two photovoltaic arrays are adjacent and have an array adjacency relationship.
[0099] For example, such as Figure 2 As shown, the first photovoltaic array row includes: photovoltaic array A, photovoltaic array B, photovoltaic array C and photovoltaic array D; the second photovoltaic array row includes: photovoltaic array E, photovoltaic array F, photovoltaic array G and photovoltaic array H.
[0100] The first photovoltaic array row and the second photovoltaic array row are adjacent photovoltaic array rows.
[0101] For photovoltaic arrays A and E, the corresponding coordinate ranges Xa and Xe intersect in the X direction, and photovoltaic arrays A and E have an array adjacency relationship, that is, photovoltaic arrays A and E are adjacent.
[0102] Similarly, for photovoltaic array A and photovoltaic array F, the corresponding coordinate ranges Xa and Xf intersect in the X direction, and photovoltaic array A and photovoltaic array F have an array adjacency relationship.
[0103] In this embodiment, based on the array position information, the array adjacent relationship of each photovoltaic array is determined, and for a certain photovoltaic array, other photovoltaic arrays adjacent thereto can be determined.
[0104] In some embodiments, determining the array connection relationship based on the array adjacent relationship can include:
[0105] Classifying the multiple groups of photovoltaic arrays based on the array adjacent relationship to obtain multiple photovoltaic array classes;
[0106] Determining a class connection relationship between the multiple photovoltaic array classes based on a first inter-class distance between the multiple photovoltaic array classes, the first inter-class distance being a shortest distance between photovoltaic arrays in two photovoltaic array classes;
[0107] Determining an adjacent array pair between photovoltaic array classes having the class connection relationship based on a second inter-class distance between the photovoltaic array classes having the class connection relationship, a distance between photovoltaic arrays in the adjacent array pair being less than a target distance range, the target distance range being determined based on the second inter-class distance;
[0108] Determining the array connection relationship based on the adjacent array pair.
[0109] In this embodiment, the multiple photovoltaic arrays are classified based on the array adjacent relationship representing whether the photovoltaic arrays are adjacent, and the array connection relationship is obtained by performing strong connectivity processing on the photovoltaic array classes.
[0110] The adjacent photovoltaic arrays can be classified into one photovoltaic array class.
[0111] The first inter-class distance between two photovoltaic array classes is determined as a shortest distance between photovoltaic arrays in the two photovoltaic array classes, i.e., a distance between the two photovoltaic arrays closest to each other in the two photovoltaic array classes.
[0112] In this embodiment, the class connection relationship between the two photovoltaic array classes, i.e., the class connection relationship between the multiple photovoltaic array classes, can be determined based on the first inter-class distance by using a minimum spanning tree method.
[0113] The two photovoltaic array classes adjacent to each other have the class connection relationship, and the two photovoltaic array classes not adjacent to each other do not have the class connection relationship.
[0114] The second inter-class distance between the two photovoltaic array classes having the class connection relationship is obtained based on the class connection relationship, and an array pair having a distance within a target distance range is found out from the two photovoltaic array classes, which is defined as an adjacent array pair.
[0115] The adjacent array pair includes two photovoltaic arrays.
[0116] The value of the target distance range of the adjacent array pair can be determined according to the second inter-array distance, for example, the second inter-array distance is D, and the value of the target distance range dist can be D+1, that is, an additional 1 meter of margin value.
[0117] In this embodiment, after the photovoltaic arrays are classified according to the array adjacency relationship, the adjacent array pairs are determined according to the distance determination, and the two photovoltaic arrays of the adjacent array pair are the photovoltaic arrays that need to be connected. According to the adjacent array pair, the array connection relationship of whether the photovoltaic arrays are connected can be obtained.
[0118] For example, for the photovoltaic arrays in the photovoltaic square array as shown in FIG. 8A, the adjacent array pairs are determined based on the array adjacency relationship, and the array connection relationship is determined, as shown in FIG. 8B. Figure 3 For example, for the photovoltaic arrays in the photovoltaic square array as shown in FIG. 8A, the adjacent array pairs are determined based on the array adjacency relationship, and the array connection relationship is determined, as shown in FIG. 8B. Figure 4 For example, for the photovoltaic arrays in the photovoltaic square array as shown in FIG. 8A, the adjacent array pairs are determined based on the array adjacency relationship, and the array connection relationship is determined, as shown in FIG. 8B.
[0119] In some embodiments, step 130 can include connecting the multiple groups of photovoltaic arrays based on the array connection relationship to obtain multiple array closed regions, and performing a set union operation on the multiple array closed regions to obtain a global closed region.
[0120] In this embodiment, based on the array connection relationship, the multiple groups of photovoltaic arrays having the array connection relationship are connected to obtain multiple array closed regions, and a set union operation is performed on all the array closed regions to obtain a global closed region.
[0121] The adjacent array pair is the two photovoltaic arrays having the array connection relationship, all the adjacent array pairs in the multiple groups of photovoltaic arrays are traversed, and the array closed region of each adjacent array pair is generated.
[0122] For example, as shown in FIG. 8B, the two photovoltaic arrays of the adjacent array pair are connected, and the line in the figure represents that the two photovoltaic arrays are the adjacent array pair, as shown in FIG. 8C. Figure 4 For example, as shown in FIG. 8B, the two photovoltaic arrays of the adjacent array pair are connected, and the line in the figure represents that the two photovoltaic arrays are the adjacent array pair, as shown in FIG. 8C. Figure 7 For example, as shown in FIG. 8B, the two photovoltaic arrays of the adjacent array pair are connected, and the line in the figure represents that the two photovoltaic arrays are the adjacent array pair, as shown in FIG. 8C.
[0123] In actual execution, different operations need to be performed according to whether the adjacent array pair has an intersection in the second direction to generate the corresponding array closed region.
[0124] In actual execution, the second direction is the length direction of the photovoltaic array, and the second direction can be the X direction of the coordinate information of the photovoltaic array.
[0125] For each photovoltaic array, based on the central point coordinates, length information and width information in the array position information, the vertex coordinates of the four vertices of the photovoltaic array can be calculated, and whether the adjacent array pair has intersection in the second direction is determined according to whether the values of the X direction of the vertex coordinates of the two photovoltaic arrays have intersection.
[0126] In some embodiments, connecting multiple groups of photovoltaic arrays based on the array connection relationship to obtain multiple array closed regions can include:
[0127] Determining that the two photovoltaic arrays having the array connection relationship have intersection in the second direction, drawing a perpendicular line at the intersection part to obtain a first closed region, and the second direction is the length direction of the photovoltaic array.
[0128] Performing a union set processing on the first closed region and the closed region corresponding to each of the two photovoltaic arrays having the array connection relationship to obtain an array closed region.
[0129] The two photovoltaic arrays having the array connection relationship are an adjacent array pair.
[0130] As shown in Figure 5 , the vertices of the first photovoltaic array are P1, P2, P3 and P4, the vertices of the second photovoltaic array are P5, P6, P7 and P8, the first photovoltaic array and the second photovoltaic array have the array connection relationship, and have intersection in the X direction.
[0131] Drawing a perpendicular line at the intersection part of the two photovoltaic arrays in the X direction to obtain a first closed region P4-P9-P6-P10-P4.
[0132] The closed region corresponding to the first photovoltaic array is P1-P2-P3-P4-P1, the closed region corresponding to the second photovoltaic array is P5-P6-P7-P8-P5, and the union set processing is performed on the first closed region and the closed region corresponding to each of the two photovoltaic arrays to obtain an array closed region P1-P2-P3-P9-P6-P7-P8-P5-P10-P4-P1.
[0133] In some embodiments, connecting multiple groups of photovoltaic arrays based on the array connection relationship to obtain multiple array closed regions can include:
[0134] Determining that the two photovoltaic arrays having the array connection relationship have no intersection in the second direction, connecting adjacent edges of the two photovoltaic arrays having the array connection relationship to obtain a second closed region, and the second direction is the length direction of the photovoltaic array.
[0135] Performing a union set processing on the second closed region and the closed region corresponding to each of the two photovoltaic arrays having the array connection relationship to obtain an array closed region.
[0136] Among them, two photovoltaic arrays that are connected by an array are adjacent array pairs.
[0137] In this embodiment, connecting the adjacent sides of two photovoltaic arrays that have an array connection relationship can connect the vertices of the two adjacent sides of the adjacent array pair to form a second closed region.
[0138] In this configuration, the vertices of two adjacent sides of an adjacent array pair are connected. A line is drawn connecting the vertices at one end of the two adjacent sides, and another line is drawn connecting the vertices at the other end of the two adjacent sides. The two lines do not intersect, and the two lines, together with the two adjacent sides, enclose a second closed region. For example... Figure 6 As shown, the vertices of the first photovoltaic array are P1, P2, P3 and P4, and the vertices of the second photovoltaic array are P5, P6, P7 and P8. The first and second photovoltaic arrays are connected and intersect in the X direction.
[0139] Connect the adjacent vertices of the two photovoltaic arrays to obtain the second closed region P2-P5-P8-P3-P2.
[0140] The closed region corresponding to the first photovoltaic array is P1-P2-P3-P4-P1, and the closed region corresponding to the second photovoltaic array is P5-P6-P7-P8-P5. The second closed region and the closed regions corresponding to the two photovoltaic arrays are combined to obtain the array closed region P1-P2-P5-P6-P7-P8-P3-P4-P1.
[0141] In some embodiments, step 140 may include: obtaining multiple sets of boundary lines of the globally closed region, and determining the boundary line with the largest enclosing area among the multiple sets of boundary lines as the envelope of the photovoltaic array.
[0142] In this embodiment, by calculating the boundary of the globally closed region, multiple sets of boundary lines can be obtained. The boundary line that encloses the largest area among the multiple sets of boundary lines is the boundary line that can enclose all photovoltaic arrays belonging to the photovoltaic array, that is, the envelope line used to divide the photovoltaic array.
[0143] like Figure 8 As shown, the envelope of this photovoltaic array is the outermost thicker line, which can surround all the photovoltaic arrays belonging to this photovoltaic array.
[0144] The following is a specific example.
[0145] like Figure 9As shown, the position information of three photovoltaic arrays of a power station is acquired, the photovoltaic array in the 6# photovoltaic array is a circular block, and is located in the upper middle of the distribution diagram of the power station; the photovoltaic array in the 7# photovoltaic array is a triangular block, and is located on the left of the distribution diagram of the power station; and the photovoltaic array in the 8# photovoltaic array is a fork-shaped block, and is located on the right of the distribution diagram of the power station.
[0146] As shown in the formula (1), for each photovoltaic array, the envelope line generation method is used to obtain the envelope line corresponding to each photovoltaic array. Figure 10
