Description

[0001] This application is a divisional application. The original application has the application number 201910425599.6 and the original application date is May 21, 2019. The entire contents of the original application are incorporated herein by reference. Technical Field

[0002] This application relates to the field of equipment installation management, and in particular to a method for obtaining electronic layout diagrams of photovoltaic systems and photovoltaic arrays. Background Technology

[0003] With the advancement of technology, photovoltaic power generation systems are being used more and more widely in people's lives, such as solar street lights, solar water heaters, and photovoltaic power stations. In order to solve the problem of series and parallel connection of photovoltaic modules in photovoltaic power generation systems, converters are generally installed under each photovoltaic module in the photovoltaic array. When any converter in the photovoltaic power generation system fails, technicians can find the photovoltaic module associated with the faulty product serial number in the electronic layout diagram of the photovoltaic array through the report from the photovoltaic power generation system. Thus, technicians only need to open the found photovoltaic module to find the faulty converter.

[0004] Currently, obtaining an electronic layout diagram can be done through the following process: Prepare a paper layout diagram of the photovoltaic array consisting of a 6x10 grid. Each cell in the grid represents a photovoltaic module, and the position of each cell in the grid corresponds to the position of the photovoltaic module in the photovoltaic array. For example, the photovoltaic module located in the first row and first column of the photovoltaic array corresponds to the cell in the first row and first column of the grid. When installing the converter, the technician records the physical location of the converter on the paper layout diagram. For example, converter 1 is installed below photovoltaic module 1 in the first row and first column of the photovoltaic array. After converter 1 is installed, the technician removes the QR code 1 containing the product serial number from converter 1 and pastes the removed QR code 1 onto cell 1A corresponding to photovoltaic module 1. When no converter is installed below the photovoltaic module... The small square in the center of the cell corresponding to the photovoltaic module is blacked out to indicate that no converter is installed below the photovoltaic module. Thus, the paper layout diagram can record the installation status of converters for each photovoltaic module in the photovoltaic array. The electronic layout diagram is manually drawn using application (APP) software. Specifically, based on the paper layout diagram, technicians add photovoltaic modules to the electronic layout diagram, manually scan the QR codes pasted in the paper physical layout to obtain the product serial numbers of the converters, and then bind the obtained product serial numbers of the converters to the corresponding photovoltaic modules in the electronic layout diagram. After all photovoltaic modules have been added to the paper layout diagram and all product serial numbers on the QR codes have been bound to the corresponding photovoltaic modules, the technicians can obtain the electronic layout diagram of the photovoltaic array.

[0005] In the electronic layout diagram obtained above, technicians need to manually scan each QR code on the paper layout diagram one by one to obtain the product serial number of the converter stored in each QR code. They also need to manually bind each product serial number to the corresponding photovoltaic module in the electronic layout diagram, which results in long manual time consumption and low efficiency in obtaining the electronic layout diagram. Summary of the Invention

[0006] This application provides a method for obtaining electronic layout diagrams of photovoltaic systems and photovoltaic arrays, which can solve the problem of low acquisition efficiency in the process of obtaining electronic layout diagrams for photovoltaic arrays. The technical solution is as follows:

[0007] Firstly, a method for obtaining electronic layout diagrams for photovoltaic arrays is provided, applicable to electronic devices, the method comprising:

[0008] The electronic device acquires a target image, which includes at least one first region. The first region is used to represent the location information and component identification of at least one photovoltaic module in the photovoltaic array. The location information is used to represent the relative position of the photovoltaic module in the photovoltaic array. The component identification includes a first type of component identification and a second type of component identification. The first type of component identification is used to indicate that a converter is installed below the photovoltaic module, and the second type of component identification is used to indicate that no converter is installed below the photovoltaic module.

[0009] The electronic device identifies each first region in the target image and obtains the location information and component identification of at least one photovoltaic module in each first region.

[0010] The electronic device obtains an electronic layout diagram of the photovoltaic array based on the location information and component identification of at least one photovoltaic module in each first region.

[0016] The electronic device obtains a list of results based on the location information and component identification of at least one photovoltaic module in each first region.

[0017] Based on each location information in the result list, the electronic device adds a virtual component at the corresponding position in the template of the electronic layout diagram. The virtual component corresponds to a photovoltaic module in the photovoltaic array.

[0018] The electronic device binds each product identifier in the result list to at least one corresponding virtual component in the template of the electronic layout diagram to obtain the electronic layout diagram of the photovoltaic array.

[0019] Based on the above possible implementation methods, there is no need to manually obtain the product identifier of each converter, nor is there a need to manually add photovoltaic modules to the electronic layout diagram, thereby reducing manual time consumption and improving the efficiency of obtaining the electronic layout.

[0020] In one possible implementation, the electronic device obtains a list of results based on the location information and component identifier of at least one photovoltaic module in each first region, including:

[0022] The electronic device associates the product identifier with the location information of at least one photovoltaic module in the first area and stores it in the results list;

[0023] When the component identifier of any photovoltaic module in any of the first regions is a component identifier of the second type, the electronic device outputs an empty identifier;

[0024] The electronic device associates the empty identifier with the location information of the component identifier and stores it in the results list.

[0025] Based on the above possible implementation methods, the electronic device obtains the electronic layout diagram based on the data in the list, which enables the location information of at least one photovoltaic module in the first area identified by the electronic device to correspond with the product identifier. When binding the product identifier, it is not necessary to determine the correspondence between the product identifier and the location information from the target image. The virtual component to be bound can be determined based on the correspondence between the product identifier and the location information in the table.

[0026] In one possible implementation, the electronic device obtains an electronic layout diagram of the photovoltaic array based on the location information and component identifier of at least one photovoltaic module in each first region, including:

[0028] Whenever a component identifier in a first region is obtained as a component identifier of the first type, the electronic device parses the component identifier to obtain the product identifier;

[0029] The electronic device binds the product identifier to at least one virtual component corresponding to at least one photovoltaic module in the first region to obtain an electronic layout diagram of the photovoltaic array.

[0076] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0077] Figure 1 This is a schematic diagram of an implementation environment provided in an embodiment of this application. See also: Figure 1 The implementation environment includes photovoltaic power generation systems and electronic equipment.

[0078] A photovoltaic (PV) power generation system is a system that converts solar energy into electrical energy. This system includes PV modules, rail mounts, and converters. PV modules convert solar energy into direct current (DC), which is then converted into alternating current (AC) by a grid-connected inverter and directly connected to the public grid to supply power to users. To provide users with higher output voltage or current, multiple PV modules can be connected in series and parallel to form a PV array. Rail mounts are installed below the PV modules to support them. Converters address the mismatch problem caused by series-parallel connection of PV modules. Each PV module can be connected to a separate converter, which can be a PV converter with independent maximum power point tracking (MPPT) functionality. In actual installation, converters are typically mounted on rail mounts, and when the PV module connected to the converter is mounted on the rail mount, the converter is hidden beneath the PV module. The PV power generation system may also include inverters and grid management equipment, and the various devices in the system support synchronous data storage.

[0079] In order to obtain an electronic layout diagram, this application provides a paper layout diagram, which is used to record the position of each photovoltaic module in the photovoltaic array and the installation of the converter in the photovoltaic power generation system. A table can be drawn on the paper layout diagram, and each cell in the table is used to represent a photovoltaic module.

[0080] An electronic device is used to generate a target image from the paper layout diagram and automatically generate an electronic layout diagram based on the target image. The electronic layout diagram is stored in various devices of the photovoltaic power generation system. The electronic device may be equipped with target APP software, which is used to recognize the target image and generate an electronic layout diagram based on the recognition result.

[0081] An electronic layout diagram is used to record the location of each photovoltaic module in the photovoltaic array and the installation status of the converter in a photovoltaic power generation system. This electronic layout diagram can be stored in multiple devices in the photovoltaic power generation system, such as the inverter, converter, and network management equipment of the photovoltaic power generation system. The electronic layout diagram supports synchronization and backup among the three, ensuring that the electronic layout diagram is not lost in the event of a single device failure. For example, if the inverter fails, after installing a new inverter, the new inverter can synchronize the electronic layout diagram from the converter or the network management equipment.

[0082] Figure 2 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. The electronic device 200 includes components that can vary significantly depending on configuration or performance. It may include one or more central processing units (CPUs) 201 and one or more memories 202. The memory 202 stores at least one instruction, which is loaded and executed by the processor 201 to implement the methods provided in the following method embodiments. Of course, the electronic device 200 may also have wired or wireless network interfaces, a keyboard, and input / output interfaces for input and output. The electronic device 200 may also include other components for implementing device functions, which will not be elaborated here.

[0083] In an exemplary embodiment, a computer-readable storage medium is also provided, such as a memory including instructions that can be executed by a processor in a terminal to complete the electronic layout diagram acquisition method for a photovoltaic array as described in the following embodiments. For example, the computer-readable storage medium may be a read-only memory (ROM), a random access memory (RAM), a compact disc read-only memory (CD-ROM), magnetic tape, a floppy disk, and an optical data storage device, etc.

[0084] The above describes the implementation environment for obtaining electronic layout diagrams. Further, to illustrate the process of obtaining electronic layout diagrams, a specific embodiment is described below. (See attached document.) Figure 3 , Figure 3This is a flowchart of a method for obtaining an electronic layout diagram of a photovoltaic array, provided in an embodiment of this application. The method flow provided in this embodiment includes:

[0085] 301. An electronic device acquires a target image, the target image including at least one first region, each first region being used to represent the location information and component identifier of at least one photovoltaic module in the photovoltaic array.

[0086] In one possible approach, the electronic device obtains the target image by photographing or scanning a paper layout diagram.

[0087] The target image is an image version of a paper layout diagram. This paper layout diagram records the location of each photovoltaic module in the photovoltaic array and the converters installed in the array. The paper layout diagram includes at least one region, each region marked with at least one module identifier, each module identifier corresponding to one photovoltaic module in the array. Each region may also be marked with a region identifier; different region identifiers indicate different numbers of photovoltaic modules represented by that region. Figure 4 , Figure 4 This is a schematic diagram of a paper layout provided in an embodiment of this application. Figure 4 The area marker within region 1 is a dashed box. This dashed box can indicate that region 1 refers to a photovoltaic module. For example... Figure 5 , Figure 5 This is a schematic diagram of a paper layout provided in an embodiment of this application. Figure 5 In region 2, the area marker is a dashed circle, which indicates that the region represents two photovoltaic modules. Of course, each first region can also have at least one area marker, and each area marker can represent one photovoltaic module, for example... Figure 6 , Figure 6 This is a schematic diagram of a paper layout provided in an embodiment of this application. Figure 6 Region 3 contains two area markers consisting of two dashed squares. Each area marker can represent a photovoltaic module. Region 3 indicates two photovoltaic modules side by side in the photovoltaic array. The area marker on the left in Region 3 is used to indicate the left photovoltaic module in the two side by side, and the area marker on the right in Region 3 is used to indicate the right photovoltaic module in the two side by side.

[0088] It should be noted that the area identifiers within each area of ​​a paper layout diagram are of the same type, meaning that the number of photovoltaic modules indicated by each area in a paper layout diagram is the same.

[0089] The paper layout diagram includes a table, with the entire table representing a photovoltaic array. Each cell in the table represents an area within the layout diagram, meaning each cell represents at least one photovoltaic module in the array. Each row in the table is numbered, such as 1, 2, 3..., and each column is also numbered, such as A, B, C... Therefore, any cell in the table can be represented by its row and column numbers. Figure 4 The region in the first row and first column of the array can be represented as A1. Then, region A1 represents at least one photovoltaic module located in the first row and first column of the photovoltaic array.

[0090] The component identification includes a first type of component identification and a second type of component identification. The first type of component identification indicates that a converter is installed below the photovoltaic module, while the second type of component identification indicates that no converter is installed below the photovoltaic module. The first type of component identification can be a QR code on the converter, which indicates the converter's product identification, such as its product serial number. The second type of component identification can be any identification other than the first type of component identification that can be recognized by software, such as a small black square.

[0091] When installing a photovoltaic (PV) array, technicians can use this paper layout diagram to record the installation positions of each converter under the PV array. When a converter is installed below a PV module, before installing the PV module, the technician can remove the QR code sticker containing the converter's QR code from the converter. This sticker also displays the converter's product identification. The technician affixes this sticker to the corresponding area on the paper layout diagram. Taking each first area on the paper layout diagram indicating a module identifier as an example, if converter 1 is installed below PV module 3 in the 2nd row and 2nd column of the PV array, after converter 1 is installed, the technician removes the QR code sticker 1 from converter 1 and affixes it to area B2 corresponding to PV module 3. If no converter is installed below a PV module, the technician blacks out the small squares in the corresponding area on the paper layout diagram. Once the PV array is installed, the technician can complete the paper layout diagram. See [link to relevant documentation]. Figure 7 and Figure 4 , Figure 7 This is a schematic diagram of target image generation provided in an embodiment of this application. After the technicians have installed the photovoltaic array, they can... Figure 4 Internal paper layout Figure 1 Complete the paper layout drawing and obtain Figure 7 Paper layout in Figure 1 ,from Figure 7 Paper layout Figure 1As can be seen from the data, the photovoltaic modules corresponding to areas B2, D2, C3, and D4 have converters installed below them, while the photovoltaic modules corresponding to areas A2-4, B3-4, C1, C4, D5, and E1-4 do not have converters installed below them.

[0092] When each first area in the paper layout diagram uses an area identifier to indicate multiple photovoltaic modules, technicians can mark the module at a preset location of at least one photovoltaic module in each first area. The preset location of each photovoltaic module can be the location of the area identifier corresponding to that photovoltaic module.

[0093] In one possible implementation, when a region identifier is used to indicate multiple photovoltaic modules within each area of ​​the paper layout diagram, if a converter is installed under any photovoltaic module indicated by any region, the technician affixes the module identifier on the converter to that region. If no converter is installed under any photovoltaic modules indicated by any region, the technician blacks out the region identifier for that region. See [link to relevant documentation]. Figure 8 and Figure 5 , Figure 8 This is a schematic diagram of target image generation provided in an embodiment of this application. After the technicians have installed the photovoltaic array, they can... Figure 5 Internal paper layout Figure 2 Complete the paper layout drawing and obtain Figure 8 Paper layout in Figure 2 ,from Figure 8 Paper layout Figure 2 As can be seen from the data, the photovoltaic modules corresponding to areas B2, D2, C3, and D4 have converters installed below them, while the photovoltaic modules corresponding to areas A2-4, B3-4, C1, C4, D5, and E1-4 do not have converters installed below them.

[0094] In one possible implementation, when multiple area labels are used to indicate multiple photovoltaic modules within each area of ​​the paper layout diagram, if a converter is installed under any photovoltaic module indicated by any area, the technician affixes the module label on the converter to the predetermined location of the photovoltaic module within that area. If a converter is not installed under any photovoltaic module indicated by any area, the technician blackens the area label corresponding to that photovoltaic module within that area. See [reference needed]. Figure 9 and Figure 6 , Figure 9 This is a schematic diagram of target image generation provided in an embodiment of this application. After the technicians have installed the photovoltaic array, they can... Figure 6 Internal paper layout Figure 3 Complete the paper layout drawing and obtain Figure 9 Paper layout in Figure 3 ,from Figure 9 Paper layout in Figure 3As can be seen, there are two photovoltaic modules indicated in area A2. The area mark on the left side of area A2 is blacked out. This blacked-out area mark indicates that a converter is installed below the photovoltaic module indicated by the area mark. There is a module label pasted on the area mark on the left side of area A2. This area mark with the pasted module label indicates that no converter is installed below the photovoltaic module indicated by the area mark.

[0095] For any given target image, it can be used to represent various parts of a paper layout diagram. When the paper layout diagram represents at least one photovoltaic array, the target image may include at least one N*M first region array, each first region array corresponding to one photovoltaic array, and each first region in each first region array corresponding to one photovoltaic module in one photovoltaic array, where N and M are both positive integers greater than 0. This application embodiment does not specifically limit the number of region arrays or the layout of the region arrays in the target image. This application embodiment uses a region array with one photovoltaic array in the target image as an example to illustrate the following steps.

[0096] The electronic device can acquire a target image of the paper layout diagram through a target app. In one possible implementation, the target app is displayed on the electronic device's screen. A technician instructs the electronic device to open the target app via the app's display. Upon receiving this instruction, the electronic device displays the user interface of the target app. When the electronic device receives a camera command, the target app activates its camera function. When the paper layout diagram is within the camera's field of view, the electronic device can take a picture of the paper layout diagram using the target app's camera function to obtain the target image. See [link to relevant documentation]. Figure 10 , Figure 10 This is a schematic diagram of an electronic layout diagram for obtaining a photovoltaic array, provided in an embodiment of this application. Figure 10 The user interface of the electronic device displays "Gallery" and "Camera" icons. Users can click the "Camera" icon, at which point the electronic device receives a photographic command and takes a picture of the paper layout diagram to obtain the target image. Alternatively, if the electronic device already has a target image of the paper layout diagram stored within it, it can directly retrieve that image. Figure 10 For example, when a user clicks the "Gallery" icon, the electronic device displays the images stored on the device. The user then searches for the target image of the paper layout diagram among the displayed images. When the electronic device clicks on the target image, the target software within the device can retrieve that image.

[0097] Alternatively, when an electronic device receives a scanning command, the target APP software of the electronic device activates the scanning function. When the paper layout diagram is within the scanning range of the electronic device, the electronic device can scan the paper layout diagram through the scanning function of the target APP software to obtain the target image.

[0098] 302. The electronic device identifies each first region in the target image and obtains the location information and component identification of at least one photovoltaic module in each first region.

[0099] The component identifier in each first region of the target image is the component identifier marked in each region of the paper layout diagram. When the electronic device identifies each first region in the target image, it can identify the component identifier of at least one photovoltaic module in each region of the paper layout diagram.

[0100] The location information of each photovoltaic module refers to the position of each photovoltaic module in the target image within the first region. The location information of each photovoltaic module can be the coordinate information of each photovoltaic module in the target image within the first region.

[0101] The process of an electronic device identifying a first region within a target image may include a process of position detection for each first region and a process of acquiring component identifiers within each first region. In one possible implementation, step 302 may be implemented through the process shown in steps 302A-302C below.

[0102] Step 302A: The electronic device detects the position of each first region in the target image and obtains the coordinate information of at least one photovoltaic module in each first region in the target image.

[0103] The coordinate information of the first region is the coordinate value of at least one photovoltaic module in the first region within the target image. The electronic device can determine the position of each first region within the target image through position detection. Subsequently, the electronic device generates a coordinate value based on the position of each first region in the target image. Then, the electronic device determines the coordinate information of at least one photovoltaic module in the first region based on the preset position of each photovoltaic module in each first region.

[0104] The electronic device determines the position of each first region within the target image by position detection, which can be achieved by any of the following methods 1, 2, and 3.

[0105] Method 1: The electronic device determines the coordinate information of each first region by directly detecting the location number of each first region.

[0106] When the row number of each first region is displayed at the first target position in the target image and the column number of each first region is displayed at the second target position, the first electronic device determines the coordinate information of each first region by detecting the row number and column number of each first region. The first target position is the column head or column tail of each column, and the first target position is the row head and row tail of each row.

[0107] In one possible implementation, when any first region is detected, the electronic device detects the row header of the row containing the first region to obtain the row number of the first region; the electronic device detects the column header of the column containing the first region to obtain the column number of the first region; the electronic device combines the row number and column number of the first region to obtain the coordinate information of the first region.

[0108] Still with Figure 5 For example, when the electronic device detects the first region at the position of the first row and the fifth column in the target image, the electronic device detects that the row number displayed in the first row is 1 and the column number displayed in the fifth column is E. The electronic device then combines the row number and column number detected by the electronic device to obtain E1, and uses E1 as the coordinate information of the first region.

[0109] Method 2: The electronic device uses a reference point as the origin of the coordinate axis and determines the coordinate information of each first region by detecting the relative position of each first region with respect to the reference point.

[0110] The reference point can be any point in the target image. For example, the top left corner of the first region in the first row and first column of the target image can be used as the reference point. The relative position includes the horizontal relative position and the vertical relative position. The horizontal relative position of any first region is the number of first regions between the first region and the reference point on the horizontal axis of the coordinate axis plus 1. The vertical relative position of any first region is the number of first regions between the first region and the reference point on the vertical axis of the coordinate axis plus 1. For example, if the number of first regions between the first region in the first row and first column of the target image and the reference point on the horizontal axis of the coordinate axis is 0, then the horizontal relative position of the first region is 0+1=1. If the number of first regions between the first region in the first row and first column of the target image and the reference point on the vertical axis of the coordinate axis is 0, then the vertical relative position of the first region is 0+1=1.

[0111] In one possible implementation, when the electronic device detects that any first region is the Xth first region on the horizontal axis of the aforementioned coordinate axis, the horizontal relative position of the first region is X. When the electronic device detects that the first region is the Yth first region on the vertical axis of the aforementioned coordinate axis, the vertical relative position of the first region is Y. The electronic device combines the horizontal relative position X and the vertical relative position Y of the first region to obtain the relative position (X, Y) of the first region, and uses the relative position (X, Y) as the coordinate information of the first region.

[0112] Method 3: The electronic device determines the coordinate axis based on at least three target identifiers in the target image; the electronic device determines the coordinate information of each first region based on the distance of the region identifier within each first region from the coordinate axis.

[0113] The at least three target identifiers are those shown on the paper layout diagram, and these at least three target identifiers are marked and may be distributed around the perimeter of the paper layout diagram, for example, Figure 4 medium paper layout Figure 4 The electronic device takes a picture of the paper layout diagram, and the target image obtained will also display corresponding target markers around it. After detecting at least three target markers, the electronic device can determine the range of the entire physical layout diagram based on these three target markers. Specifically, when the electronic device detects three target markers distributed at right angles on the target image, these three target markers include a first target marker, a second target marker, and a third target marker. The electronic device can use the center of the first target marker as the origin of the coordinate axis, the line connecting the center of the second target marker and the center of the first target marker as the horizontal axis of the coordinate axis, and the line connecting the center of the third target marker and the center of the first target marker as the vertical axis of the coordinate axis. Thus, the electronic device can determine a coordinate axis, and the coordinate plane in which the coordinate axis is located can include at least one first region within the target image.

[0114] The area markers are labels manually marked on each area of ​​the paper layout map, for example, Figure 4 The dashed box within each first region in the diagram. Then, the electronic device can use the coordinate information of each region identifier on the coordinate plane as the coordinate information of each first region.

[0115] In one possible implementation, when the electronic device detects that any region identifier is the Xth region identifier in the direction of the horizontal axis of the above coordinate axis, the horizontal coordinate of the region identifier is X. When the electronic device detects that the region identifier is the Yth region identifier in the direction of the vertical axis of the above coordinate axis, the vertical coordinate of the region identifier is Y. The coordinate information of the region identifier is (X, Y). The electronic device can use the coordinate information (X, Y) of the region identifier as the coordinate information of the first region where the region identifier is located.

[0116] The coordinate information of the first region can be determined based on any of the three methods mentioned above. When there is one photovoltaic module in the first region, the coordinate information of the first region can be used as the coordinate information of the photovoltaic module in the first region. When the first region indicates multiple photovoltaic modules, the electronic device determines the coordinate information of each photovoltaic module in the first region according to the preset position of each photovoltaic module in the first region. In one possible implementation, when the preset position of any photovoltaic module in the first region is Z preset positions and the coordinate information of the first region is (X, Y), (X, Y, Z) can be used as the coordinate information of the photovoltaic module.

[0117] When there are multiple area identifiers within each first region, the preset position of each photovoltaic module within that first region can be the location of the area identifier of each photovoltaic module within that first region. The electronic device can identify each area identifier according to the order of the area identifiers within the first region to obtain the coordinate information of each photovoltaic module indicated by the first region. For example, Figure 9 The first area A2 has two area markers. The area marker on the left is blacked out, and the area marker on the right shows the component identifier. The electronic device identifies the first area marker on the left side of the first area A2 from left to right. The coordinate information of the photovoltaic component indicated by the area marker is (A, 2, 1). Then, the electronic device continues to identify the second area marker on the right side of the first area A2. When the second area marker is identified, the coordinate information of the photovoltaic component indicated by the second area marker is (A, 2, 2).

[0118] It should be noted that the embodiments of this application do not specifically limit the order in which the electronic device identifies the various area identifiers in the first area.

[0119] Step 302B: The electronic device uses the coordinate information of at least one photovoltaic module in each first region as the location information of at least one photovoltaic module in the first region.

[0120] Taking the example in step 302A as an example, the obtained coordinate information E1 is used as the location information of the photovoltaic module in the first region of identification.

[0121] Step 302C: The electronic device identifies at least one photovoltaic module at a preset location in each first region to obtain at least one module identifier in each first region.

[0122] The preset location can be the center of the first region or other locations within the first region. The number of preset locations in the first region is the same as the number of photovoltaic modules within the first region; that is, each preset location corresponds to one photovoltaic module. This application embodiment does not specifically limit the preset location. For example, when the electronic device recognizes a QR code at a preset location in any region, it can use the QR code as the component identifier for that first region. When the electronic device recognizes a template string at a preset location in any region, it can use the target string as the component identifier for that first region. Both the QR code and the string are first-type component identifiers. This application embodiment uses a QR code as an example for illustration.

[0123] It should be noted that the electronic device can first perform position detection on each first region, and then obtain the component identifier within each first region. The electronic device can also perform position detection and component identifier acquisition on the next first region in the target image after completing the position detection and component identifier acquisition of each first region. The electronic device can also perform the position detection step and the component identifier acquisition step on a first region simultaneously.

[0124] 303. The electronic device obtains an electronic layout diagram of the photovoltaic array based on the location information and component identification of at least one photovoltaic module in each first region.

[0125] The electronic layout diagram includes multiple virtual components, each of which corresponds to a photovoltaic module in the photovoltaic array. The position of each virtual component in the electronic layout diagram is also the position of the corresponding photovoltaic module in the photovoltaic array.

[0126] The virtual component is a preset component for drawing electronic layout diagrams provided in advance by technicians. The virtual component can be of any form, and the embodiments of this application do not specifically limit the virtual component.

[0127] The electronic device can implement step 303 through either process 1 or process 2. Process 1 involves the electronic device obtaining a result list based on the location information and component identifier of at least one photovoltaic module in each first region, and then obtaining the electronic layout diagram based on the contents of the result list. It is evident that process 1 does not obtain the electronic layout based on real-time identification results. Process 2, on the other hand, involves obtaining the electronic layout diagram based on the location information and component identifier obtained through real-time identification.

[0128] To further illustrate the process shown in Procedure 1, see [link to procedure]. Figure 13 , Figure 13 This is a flowchart of a method for obtaining an electronic layout diagram of a photovoltaic array, provided in an embodiment of this application. The method includes the following steps:

[0129] Step 303A: When the component identifier of any photovoltaic module in any first region is a component identifier of the first type, the electronic device parses the component identifier to obtain the product identifier indicated by the component identifier.

[0130] The electronic device can detect the component identifier to determine whether the detected component identifier is a first type of component identifier. In one possible implementation, the electronic device detects the component identifiers in the target area. When it detects that any component identifier in the first area is a first type of component identifier, the electronic device performs this step 303. Taking a QR code as an example, when the electronic device detects that any component identifier in the first area is a QR code, it parses the QR code to obtain the product serial number indicated by the QR code.

[0131] Step 303B: The electronic device associates the product identifier with the location information of at least one photovoltaic module in the first area and stores it in the result list.

[0132] The electronic device can store the product identifier and the location information of each photovoltaic module in the first region in the same row of the result list, so that the product identifier is associated with the location information of at least one photovoltaic module in the first region.

[0133] Step 303C: When the component identifier of any photovoltaic module in any first region is a second type of component identifier, the electronic device outputs an empty identifier.

[0134] The method by which an electronic device determines whether a component identifier is a second type of component identifier is the same as the method by which it determines whether a component identifier is a first type of component identifier. The embodiments of this application will not elaborate on the method by which an electronic device determines whether a component identifier is a second type of component identifier.

[0135] The empty identifier can be represented by any string, such as NA, to indicate that the component identifier cannot indicate a product serial number.

[0136] It should be noted that, in one possible implementation, when the component identifier of any photovoltaic module in any first region is a component identifier of the second type, the electronic device does not output any results.

[0137] Step 303D: The electronic device associates the empty identifier with the location information of the photovoltaic module and stores it in the result list.

[0138] The electronic device can store the empty identifier and the location information of the photovoltaic module in the same row of the results list, so that the empty identifier is associated with the location information of the photovoltaic module.

[0139] It should be noted that the process shown in steps 303A-30D is the process by which an electronic device obtains a result list based on the location information and component identifier of at least one photovoltaic module in each first region, and the empty identifier and product identifier obtained by the electronic device in steps 303A and 303C can be used as product descriptions in the result list.

[0140] To further illustrate the status of each photovoltaic module and converter in the photovoltaic array in the result list, the electronic device can add component descriptions to the result list. In one possible implementation, when the component identifier of any photovoltaic module in any first region is a first type of component identifier, the component description output by the electronic device is "PV module and converter installed". When the component identifier of any photovoltaic module in any first region is a second type of component identifier, the component description output by the electronic device is "PV module installed, converter not installed". When the component identifier of any first region is a second type of component identifier, the component description output by the electronic device is "empty identifier" or empty. The electronic device associates the component description with the location information of the photovoltaic module and stores it in the result list.

[0141] Taking the first region indicating a photovoltaic module as an example, as shown in Table 1, it can be seen that there is no module identification in the first region A1, that is, no photovoltaic module and converter are installed at the position corresponding to the first region A1 in the photovoltaic array; the module identification in the first region E1 is type 2, that is, a photovoltaic module is installed at the position corresponding to the first region E1 in the photovoltaic array, but no converter is installed; the module identification in the first region B2 is type 1, that is, a photovoltaic module and converter are installed at the position corresponding to the first region B2 in the photovoltaic array, and the product identification of the installed converter is XXXXXXXX.

[0142] Table 1

[0143] Serial Number Location information Component Description Product Description 1 A1 NA NA 2 B1 NA NA … … … … 5 E1 Photovoltaic modules are installed, but the converter is not installed. NA … … … … 12 B2 It is equipped with photovoltaic modules and converters. XXXXXXXX … … … … 59 I6 NA NA 60 J6 NA NA

[0144] In one possible implementation, the electronic device may also not store information related to the first region without component identification in the result list, but only store information related to the first region with component identification. This improves the efficiency of generating the result list and reduces the memory consumption of the electronic device. Referring to Table 2, it can be seen that Table 2 does not store information related to the first region without component identification, but only stores information related to the first region with component identification.

[0145] Table 2

[0146] Serial Number Location information Component Description Product Description 1 E1 Photovoltaic modules are installed, but the converter is not installed. NA 2 A2 Photovoltaic modules are installed, but the converter is not installed. NA ... ... ... ... 5 D2 It is equipped with photovoltaic modules and a converter. YYYYYYY ... ... ... ... 11 E3 Photovoltaic modules are installed, but the converter is not installed. NA 12 A4 Photovoltaic modules are installed, but the converter is not installed. NA ... ... ... ... 16 E4 Photovoltaic modules are installed, but the converter is not installed. NA

[0147] Step 303E: Based on each location information in the result list, the electronic device adds a virtual component at the corresponding position in the template of the electronic layout diagram. The virtual component corresponds to a photovoltaic module in the photovoltaic array.

[0148] The template for the electronic layout diagram is a template for drawing electronic layout diagrams provided in advance by technicians. The electronic device can draw the electronic layout diagram on the template based on the location information and product identification of at least one photovoltaic module in each first area.

[0149] The electronic device can add virtual components within the template of the electronic layout diagram based on the location information read from the result list. In one possible implementation, whenever the electronic device reads a location information from the result list, it adds a virtual component at the corresponding position within the template of the electronic layout diagram.

[0150] Step 303F: The electronic device binds each product identifier in the result list to at least one virtual component corresponding to the template of the electronic layout diagram to obtain the electronic layout diagram of the photovoltaic array.

[0151] The at least one virtual component corresponds to at least one photovoltaic component in the first area where the product identifier is located.

[0152] In one possible implementation, the electronic device executes step 303F whenever a product identifier is read from the result list. It should be noted that the virtual component is not bound to an empty identifier, but only to a product identifier. For example, if the product description in the first row of Table 2 is an empty identifier NA, then the electronic device does not need to bind the empty identifier NA to the corresponding virtual component.

[0153] The electronic device binds the product identifier to the corresponding virtual component, which can be achieved through any of the methods 4-6 below.

[0154] Method 4: The electronic device directly displays any product identifier on at least one corresponding virtual component.

[0155] Method 5: The electronic device displays any product identifier on an icon and displays that icon on at least one corresponding virtual component.

[0156] Method 6: The electronic device associates and stores any product identifier with the icon information of an icon, and displays the icon indicated by the icon information on at least one corresponding virtual component.

[0157] The icon information can be any information used to uniquely identify an icon, and the embodiments of this application do not specifically limit the icon information.

[0158] Taking Table 2 as an example, when the electronic device reads the product identifier YYYYYYY in the 5th row of Table 2, the electronic device associates and stores the product identifier YYYYYYYY with icon information 1, and stores the icon 1 indicated by icon information 1 on the corresponding virtual component in the electronic layout diagram.

[0159] Once the electronic device has read at least one data from the result list, it means that the electronic device has added at least one corresponding virtual component to the template of the electronic layout diagram, and at least one product identifier in the result list has been bound to the corresponding virtual component. Then, the electronic layout diagram will obtain the template of the electronic layout diagram at this time as the electronic layout diagram.

[0160] For example Figure 10 and Figure 7 When electronic devices Figure 7 After the target image 1 is identified, a result list X is obtained. Based on the location information and product identifier in the result list X, the electronic device can obtain the electronic layout. Figure 1 The electronic layout Figure 1 Each icon in the image is associated with a product identifier, and each icon is displayed on a virtual component. It can be seen that a converter is installed below the photovoltaic module corresponding to the virtual component.

[0161] For example, Figure 11 and Figure 8 , Figure 11 This is a schematic diagram of an electronic layout diagram for obtaining a photovoltaic array, provided in an embodiment of this application. When the electronic device... Figure 8 After the target image 2 is identified, a result list Y can be obtained. Based on the location information and product identifier in the result list Y, the electronic device can obtain the electronic layout. Figure 2 The electronic layout Figure 2 Each icon in the diagram is associated with a product identifier, and each icon is displayed on two virtual components. For example, the icons are displayed on virtual components 1 and 2, and it can be seen that converters are installed below the two photovoltaic modules corresponding to virtual components 1 and 2.

[0162] For example, Figure 12 and Figure 9 , Figure 12 This is a schematic diagram of an electronic layout diagram for obtaining a photovoltaic array, provided in an embodiment of this application. When the electronic device... Figure 9 After the target image 3 is identified, a result list Z can be obtained. The electronic device uses the location information and product identifier in the result list Z. Figure 9 Each first region can correspond to a virtual component, thus obtaining the electronic layout. Figure 3 The electronic layout Figure 3 Each icon in the list is bound to a product identifier, and each icon is displayed on a virtual component. For example, icon 3 is displayed on virtual component 3. Figure 9 Each first region in the diagram can indicate two photovoltaic modules. Correspondingly, virtual module 3 also corresponds to two photovoltaic modules. It can be seen that converters are installed below the two photovoltaic modules corresponding to virtual module 3.

[0163] The electronic device obtains the electronic layout diagram based on the result list. The electronic device can also obtain the electronic layout diagram based on real-time recognition results, such as in process 2 described above. For further explanation of process 2, see [link to documentation]. Figure 14 , Figure 14 This is a flowchart of a method for obtaining an electronic layout diagram of a photovoltaic array, provided in an embodiment of this application. The method includes the following steps:

[0164] Step 3031: Whenever the electronic device obtains the location information of at least one photovoltaic module in a first region, it adds at least one virtual component to the template of the electronic layout diagram of the photovoltaic array, and the virtual component corresponds to one photovoltaic module in the photovoltaic array.

[0165] After identifying any first region in the target image, the electronic device obtains the location information of at least one photovoltaic module in the first region. The electronic device can directly execute this step 3031 based on the obtained location information of the first region.

[0166] Of course, the electronic device can also perform this step 3031 whenever it obtains the location information of all photovoltaic modules in a first region.

[0167] Step 3032: Whenever the electronic device obtains a component identifier of the first type in a first area, it parses the component identifier to obtain the product identifier.

[0168] After the electronic device identifies any preset position in any first region of the target image, it obtains the component identifier of the first region. When the component identifier is a first type of component identifier, the electronic device executes this step 3032.

[0169] Step 3033: The electronic device binds the product identifier to at least one virtual component corresponding to at least one photovoltaic module in the first region to obtain the electronic layout diagram of the photovoltaic array.

[0170] Once the electronic device has completed the identification of at least one first region in the target image, it means that the electronic device has added at least one corresponding virtual component to the template of the electronic layout diagram, and has bound at least one product identifier to the corresponding virtual component. Then, the electronic layout diagram will obtain the template of the electronic layout diagram at this time as the electronic layout diagram.

[0171] It should be noted that when there are multiple component identifiers in any first region, and any one of these component identifiers is a first type of component identifier, the electronic device will bind the product identifier parsed from the first type of component identifier to multiple virtual components, wherein these multiple virtual components correspond to the multiple component identifiers in the first region. For example, Figure 10 Electronic layout in Figure 1 When there are component identifier 1 and component identifier 2 in the first area, where component identifier 1 corresponds to virtual component 1 in the electronic layout diagram and component identifier 2 corresponds to virtual component 2 in the electronic layout diagram, when virtual component 2 is a first type of virtual component, the electronic device will bind the product number parsed from component identifier 2 to virtual components 1 and 2.

[0172] Based on the above Figure 13 and Figure 14 As shown in the process, the electronic device can directly generate an electronic layout diagram based on the location information and component identification of at least one photovoltaic module in the first region without human intervention, thereby reducing manual time consumption and improving the efficiency of electronic layout diagram generation.

[0173] 304. The electronic device stores the electronic layout diagram of the photovoltaic array in multiple devices within the photovoltaic power generation system, and the multiple devices within the photovoltaic power generation system support data synchronization and backup.

[0174] The photovoltaic power generation system includes multiple devices such as converters, inverters, and network management equipment. These electronic devices can store the electronic layout diagram of the photovoltaic array in any device via wired or wireless network. When the photovoltaic power generation system issues a converter fault alarm, technicians can connect the network management equipment or a mobile phone to the inverter. The mobile phone can then read the electronic layout diagram of the photovoltaic array from the converter and display it on the user interface. This allows technicians to identify the virtual component bound to the faulty converter from the electronic layout diagram based on the product identifier of the faulty converter reported by the photovoltaic power generation system. Since each virtual component corresponds to a photovoltaic module in the photovoltaic array, technicians can determine the installation location of the faulty converter.

[0175] When any device storing the electronic layout diagram fails, technicians can replace it with a new device. Since multiple devices storing the electronic layout diagram support data synchronization and backup, the new device can synchronize the electronic layout diagram from other devices that store it, thus preventing the loss of the electronic layout diagram.

[0176] See Figure 15 , Figure 15 This is a schematic diagram illustrating an application scenario provided in an embodiment of this application. Figure 15 The inverter can be connected to electronic devices and network management devices via wireless network. Electronic devices can import electronic layout diagrams into the inverter and network management devices via wireless network. The inverter can import the electronic layout diagrams imported by the electronic devices into the converter. When the inverter fails and is replaced by a new inverter, the new inverter can synchronize the electronic layout diagram from the converter or network management device so that the electronic layout diagram in the inverter can be directly displayed on other electronic devices.

[0177] In this embodiment, an electronic device identifies each first region in a target image to obtain the location information and component identifier of at least one photovoltaic module in each first region. Based directly on the location information and component identifier of each photovoltaic module, an electronic layout diagram can be obtained without manually obtaining the product identifier of each converter or manually adding photovoltaic modules to the electronic layout diagram, thus reducing manual time consumption and improving the efficiency of obtaining the electronic layout. Furthermore, the electronic device can first identify the component identifier in the target image, and then identify the first region where the component identifier is located to obtain the location information of at least one photovoltaic module in that first region. This avoids identifying first regions without component identifiers, thereby improving the efficiency of the electronic device in identifying the target image. Moreover, when the electronic device stores the relevant information of the first region with component identifiers in the result list, the efficiency of generating the result list is improved, and the memory consumption of the electronic device is reduced. Furthermore, the electronic layout diagram obtained by the electronic device can be stored in multiple devices within the photovoltaic power generation system, and these multiple devices can support data synchronization and backup, thereby preventing the loss of the electronic layout diagram.
