Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0019] It is understood that before using the technical solutions disclosed in the various embodiments of the present invention, users should be informed of the types, scope of use, and usage scenarios of the personal information involved in the present invention and their authorization should be obtained in accordance with relevant laws and regulations through appropriate means.

[0020] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] In the equipment management of photovoltaic power plants, it is essential to clearly define the physical location of the modules to ensure operational efficiency. Traditionally, operators rely on manually checking the serial numbers (SNs) of each photovoltaic module and recording the location of each SN. After scanning the SNs, a site location view of the power plant is manually drawn. This process is time-consuming, labor-intensive, prone to recording and drawing errors due to human error, and inefficient, making it unsuitable for the equipment management needs of large-scale photovoltaic power plants.

[0022] Based on this, the present invention provides a method for generating a position view of photovoltaic modules. In response to a trigger operation on a scanning device, the method acquires positioning data and encoding information corresponding to the photovoltaic modules. The positioning data is obtained through a navigation system configured in the scanning device. Based on the positioning data corresponding to each photovoltaic module, a view coordinate system for the photovoltaic modules is constructed, and the position coordinates of each photovoltaic module in the view coordinate system are determined. The position coordinates and encoding information of each photovoltaic module are then associated to construct a position view. On the one hand, the positioning data acquired by the navigation system can improve the accuracy of the determined position coordinates of the photovoltaic modules, thereby improving the accuracy of the position view. On the other hand, it directly determines the position coordinates of each photovoltaic module based on the acquired positioning data without requiring manual recording of the photovoltaic module's position, thus improving the efficiency of position view generation.

[0023] The method for generating a position view of photovoltaic (PV) modules provided in this invention can be applied to PV power plants to draw position views of the PV modules configured therein. Specifically, this method can be applied to a server in the PV power plant. The server is communicatively connected to a scanning device equipped with a navigation system for acquiring positioning data corresponding to the PV modules. After receiving the positioning data from the scanning device, the server constructs a view coordinate system based on this data and sequentially determines the position coordinates of each PV module in the PV power plant. Simultaneously, it associates the position coordinates and encoding information of each PV module to construct the position view.

[0024] According to an embodiment of the present invention, a method for generating a position view of a photovoltaic module 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.

[0025] This embodiment provides a method for generating a location view of a photovoltaic module, which can be used in the aforementioned photovoltaic power plant. Figure 1 This is a schematic flowchart of a first method for generating a position view of a photovoltaic module according to an embodiment of the present invention, as shown below. Figure 1 As shown, the process includes the following steps: Step S101: In response to the trigger operation of the scanning device, the positioning data and encoding information corresponding to the photovoltaic module are obtained.

[0026] In this embodiment of the invention, the scanning device is equipped with a navigation system that can record the positioning data of the scanning device in real time. The scanning device obtains the coding information of the photovoltaic module through a barcode scanning operation. Simultaneously, while performing the barcode scanning operation, the scanning device records the positioning data of the navigation system and uses it as the positioning data corresponding to the photovoltaic module. In response to a trigger operation on the scanning device, the barcode scanning operation of the scanning device is triggered, and the coding information and positioning data corresponding to the photovoltaic module are obtained through the scanning device.

[0027] For example, Figure 2 This is a schematic diagram of the layout of a photovoltaic module in the method for generating a position view of a photovoltaic module according to an embodiment of the present invention. Figure 2 Taking an example, this invention will explain how to obtain the positioning data and coding information corresponding to photovoltaic modules. Figure 2 As shown, the user scans photovoltaic modules A through H sequentially using a scanning device. Each time the user reaches the location of a photovoltaic module, the scanning device is triggered to scan the module, obtaining the module's encoding information and the scanning device's positioning data. At this time, the scanning device and the photovoltaic module are in the same location, so the scanning device's positioning data can be used as the corresponding positioning data for the photovoltaic module. The user scans all photovoltaic modules sequentially to obtain the positioning data and encoding information for all photovoltaic modules. Based on the photovoltaic module position view generation method of this invention, a position view is constructed in real time, thereby generating the position view simultaneously during the user's scanning process, achieving rapid generation of the position view.

[0028] In one alternative implementation, to avoid erroneous recording of the positioning data corresponding to the photovoltaic module due to accidental triggering of the scanning device, the scanning device only records the positioning data of the navigation system when it obtains the encoded information through the scanning operation.

[0029] In one specific implementation, the scanning device can be an RFID scanning device, and the encoding information of the photovoltaic module can be an SN device code.

[0030] Step S102: Based on the positioning data corresponding to each photovoltaic module, construct a view coordinate system for the photovoltaic modules and determine the position coordinates of each photovoltaic module in the view coordinate system.

[0031] In this embodiment of the invention, after obtaining the positioning data corresponding to each photovoltaic module, a view coordinate system is constructed based on the positioning data corresponding to the first photovoltaic module. After the view coordinate system is constructed, the position offset of each photovoltaic module in the view coordinate system is determined based on the positioning deviation between the positioning data corresponding to each photovoltaic module and the positioning data corresponding to other photovoltaic modules, thereby locating each photovoltaic module in the view coordinate system and determining the position coordinates of each photovoltaic module in the view coordinate system.

[0032] In one optional implementation, a view coordinate system is constructed based on the positioning data corresponding to the first photovoltaic module. This can be achieved by using the location corresponding to the positioning data of the first photovoltaic module as the origin of the view coordinate system and using latitude and longitude as the two coordinate axes of the view coordinate system. Alternatively, the view coordinate system can be constructed by using the relative position direction between the positioning data of the second photovoltaic module and the positioning data of the first photovoltaic module as one of the coordinate axes of the view coordinate system.

[0033] In one optional implementation, the position offset of each photovoltaic module in the view coordinate system is determined based on the positioning deviation between the positioning data corresponding to each photovoltaic module and the positioning data corresponding to other photovoltaic modules. This can be done by determining the position offset of each photovoltaic module in the view coordinate system based on the positioning deviation between the positioning data corresponding to each photovoltaic module and the positioning data corresponding to the first photovoltaic module. Alternatively, the position offset of each photovoltaic module in the view coordinate system can be determined sequentially based on the positioning deviation between the positioning data corresponding to two consecutive photovoltaic modules, thereby determining the position offset of the next photovoltaic module based on the position offset of the previous photovoltaic module.

[0034] Step S103: Associate the location coordinates and coding information of each photovoltaic module to construct a location view.

[0035] In this embodiment of the invention, the position coordinates of each photovoltaic module in the view coordinate system are associated with its corresponding coding information, thereby associating the coding information and position coordinates of each photovoltaic module in the view coordinate system to obtain a position view.

[0036] The method for generating a position view of a photovoltaic module provided in this embodiment of the invention responds to a trigger operation on a scanning device by acquiring the positioning data corresponding to the photovoltaic module through a navigation system configured in the scanning device. Based on the positioning data corresponding to each photovoltaic module, a view coordinate system for the photovoltaic module is constructed, and the position coordinates of each photovoltaic module in the view coordinate system are determined. The position coordinates of each photovoltaic module are associated with the encoding information to construct a position view. On the one hand, the positioning data acquired by the navigation system can improve the accuracy of the determined position coordinates of the photovoltaic modules, thereby improving the accuracy of the position view. On the other hand, the position coordinates of each photovoltaic module can be determined directly based on the acquired positioning data without the need for manual recording of the position of the photovoltaic modules, thereby improving the drawing efficiency of the position view.

[0037] This embodiment provides a method for generating a location view of a photovoltaic module, which can be used in the aforementioned photovoltaic power plant. Figure 3 This is a schematic diagram of a second process for generating a position view of a photovoltaic module according to an embodiment of the present invention, as shown below. Figure 3 As shown, the process includes the following steps: Step S301: In response to a trigger operation on the scanning device, acquire the positioning data and encoding information corresponding to the photovoltaic module. For details, please refer to [link to relevant documentation]. Figure 1 Step S101 of the illustrated embodiment will not be described again here.

[0038] Step S302: Based on the positioning data corresponding to each photovoltaic module, construct a view coordinate system for the photovoltaic modules and determine the position coordinates of each photovoltaic module in the view coordinate system.

[0039] In this embodiment of the invention, step S302, based on the positioning data corresponding to each photovoltaic module, constructs a view coordinate system for the photovoltaic modules, including: Step S3021: Based on the positioning data corresponding to the first photovoltaic module obtained by the scanning device, determine the origin of the view coordinate system.

[0040] In this embodiment of the invention, the location information of the first photovoltaic module is determined based on the location data corresponding to the first photovoltaic module, and the location information of the first photovoltaic module is used as the origin of the view coordinate system.

[0041] Step S3022: Based on the positioning data of the first photovoltaic module and the second photovoltaic module obtained by the scanning device, determine the relative position direction of the second photovoltaic module relative to the first photovoltaic module, and use the relative position direction as the first coordinate direction of the view coordinate system.

[0042] In this embodiment of the invention, in step S3021, the position information of the first photovoltaic module is determined. Based on the obtained positioning data corresponding to the first and second photovoltaic modules, the positional offset of the second photovoltaic module relative to the first photovoltaic module is determined, thereby determining the relative positional direction of the second photovoltaic module relative to the first photovoltaic module, and using this relative positional direction as the first coordinate direction of the view coordinate system. The specific direction of determining the positional offset of the second photovoltaic module relative to the first photovoltaic module can be shown in step S3024 below, which will not be described in detail here.

[0043] For example, Figure 4 This is a schematic diagram of the view coordinate system in the method for generating a position view of a photovoltaic module according to an embodiment of the present invention, as shown below. Figure 2 and Figure 4 As shown, the positioning data corresponding to the first photovoltaic module acquired by the scanning device is the positioning data corresponding to photovoltaic module A. The position information of photovoltaic module A is determined based on the positioning data corresponding to photovoltaic module A, and this is used as the origin of the view coordinate system. The positioning data corresponding to the second photovoltaic module acquired by the scanning device is the positioning data corresponding to photovoltaic module B. Based on the positioning data corresponding to photovoltaic module A and photovoltaic module B, the position offset of photovoltaic module B relative to photovoltaic module A is determined. The relative position direction of photovoltaic module B relative to photovoltaic module A is used as the first coordinate direction of the view coordinate system, that is, the direction of the line connecting the position point of photovoltaic module B and the position point of photovoltaic module A is used as the first coordinate direction of the view coordinate system. Figure 4 In the first coordinate direction, that is, the y-axis direction.

[0044] Step S3023: Construct the view coordinate system based on the origin and the first coordinate direction of the view coordinate system.

[0045] In this embodiment of the invention, based on the determined first coordinate direction, the second coordinate direction and the third coordinate direction of the view coordinate system are determined respectively, thereby constructing the view coordinate system based on the determined coordinate origin and the three coordinate directions.

[0046] In this embodiment of the invention, step S302, determining the position coordinates of each photovoltaic module in the view coordinate system, includes: Step S3024: For each photovoltaic module, based on the positioning data of the photovoltaic module and the photovoltaic module preceding it, determine the positional offset of the photovoltaic module relative to the previous photovoltaic module.

[0047] In this embodiment of the invention, for each photovoltaic module, after obtaining its corresponding positioning data, the positional offset of the photovoltaic module relative to the previous photovoltaic module is determined based on the positioning deviation between the positioning data of the photovoltaic module and the positioning data of the previous photovoltaic module.

[0048] In one optional implementation, the navigation system configured in the scanning device is an inertial navigation system. The positioning data acquired by the navigation system includes gyroscope data and acceleration data along the movement path from the previous photovoltaic module to the current photovoltaic module. The gyroscope data is converted into Euler angles to obtain the attitude information corresponding to the photovoltaic module. Based on the attitude information corresponding to the photovoltaic module, the acceleration data is corrected, thereby correcting the position data of the photovoltaic module in each direction based on the attitude information to obtain the acceleration information corresponding to the photovoltaic module. The acceleration information corresponding to the photovoltaic module is integrated twice. The velocity information corresponding to the photovoltaic module is obtained through the first integration calculation, and the displacement information corresponding to the photovoltaic module is obtained through the second integration calculation, that is, the position offset of the photovoltaic module relative to the previous photovoltaic module is obtained.

[0049] In one optional implementation, the navigation system configured in the scanning device is a satellite navigation system. The positioning data acquired by the navigation system includes the latitude and longitude data of the current photovoltaic module. Subtracting the positioning data of the previous photovoltaic module from the positioning data of the current photovoltaic module yields the positional offset of the photovoltaic module relative to the previous photovoltaic module.

[0050] In one optional implementation, the scanning device is equipped with an inertial navigation system and a satellite navigation system. The positioning data includes first positioning data and second positioning data, wherein the first positioning data is acquired through the inertial navigation system and the second positioning data is acquired through the satellite navigation system. Accordingly, in step S3024, the positional offset of the photovoltaic module relative to the previous photovoltaic module is determined based on the first positioning data and the second positioning data, respectively, and the two positional offsets are weighted to accurately determine the positional offset of the photovoltaic module relative to the previous photovoltaic module. Specifically, based on the first positioning data of the photovoltaic module, a first positional offset of the photovoltaic module relative to the previous photovoltaic module is determined; based on the second positioning data of the photovoltaic module and the previous photovoltaic module, a second positional offset of the photovoltaic module relative to the previous photovoltaic module is determined; and a weighted calculation is performed on the first and second positional offsets of the photovoltaic module relative to the previous photovoltaic module to obtain the positional offset of the photovoltaic module relative to the previous photovoltaic module.

[0051] In one optional implementation, the gyroscope data in the first positioning data of the photovoltaic module is converted into Euler angles to obtain the attitude information corresponding to the photovoltaic module; based on the attitude information corresponding to the photovoltaic module, the acceleration data in the first positioning data of the photovoltaic module is corrected, thereby correcting the position data of the photovoltaic module in various directions to obtain the acceleration information corresponding to the photovoltaic module; the acceleration information corresponding to the photovoltaic module is integrated twice. The acceleration information is integrated through the first integration calculation to obtain the velocity information corresponding to the photovoltaic module, and the velocity information is integrated through the second integration calculation to obtain the first position offset of the photovoltaic module relative to the previous photovoltaic module.

[0052] In one optional implementation, after acquiring the first positioning data, the gyroscope data therein is preprocessed by filtering the gyroscope data to eliminate zero-point drift and performing temperature compensation to eliminate temperature offset, thereby ensuring the accuracy of the gyroscope data, and thus ensuring the accuracy and reliability of correcting the acceleration data and the second positioning data based on the attitude information obtained from the gyroscope data.

[0053] In one optional implementation, after acquiring the first positioning data, the acceleration data is preprocessed by performing gravity separation and digital filtering to ensure the accuracy of the acceleration data. Specifically, gravity separation can be performed on the acceleration data using the following formula:

[0054]

[0055] in, It is the acceleration due to gravity. It is a weighting coefficient less than 1. The acceleration data is the component in the direction of gravity. This represents the value of the component of acceleration data in the direction of gravity after separation by gravity.

[0056] In one alternative implementation, the second positioning data of the photovoltaic module is subtracted from the second positioning data of the previous photovoltaic module to obtain the second position offset of the photovoltaic module relative to the previous photovoltaic module.

[0057] In one optional implementation, in order to improve the accuracy of the calculated second position offset, before subtracting the second positioning data of the photovoltaic module from the second positioning data of the previous photovoltaic module, the directional deviation in the obtained second positioning data of the photovoltaic module is corrected based on the attitude information corresponding to the photovoltaic module.

[0058] In one optional implementation, the positional offset of the photovoltaic module relative to the previous photovoltaic module is obtained by weighted calculation based on a first positional offset and a second positional offset of the photovoltaic module relative to the previous photovoltaic module, as shown in the following formula:

[0059] in, For photovoltaic modules The positional offset relative to the previous photovoltaic module For photovoltaic modules Relative to the first position offset of the previous photovoltaic module, For photovoltaic modules The second position offset relative to the previous photovoltaic module, The weighting coefficients corresponding to the first position offset are: The weighting coefficient corresponding to the second position offset is, and .

[0060] Step S3025: Determine the position coordinates of the photovoltaic module based on the position coordinates of the previous photovoltaic module and the position offset of the photovoltaic module relative to the previous photovoltaic module.

[0061] In this embodiment of the invention, the position coordinates of the photovoltaic module are obtained by superimposing the position offset of the photovoltaic module relative to the previous photovoltaic module on the position coordinates of the previous photovoltaic module, thereby locating and displaying the photovoltaic module in the view coordinate system. Figure 5 This is a schematic diagram of the position of a photovoltaic module in the view coordinate system according to an embodiment of the present invention, in the method for generating a position view of a photovoltaic module. Figure 2 and Figure 5 As shown, the user sequentially scans the photovoltaic module using the scanning device. Each time the scanning device triggers a scan operation on the photovoltaic module, it acquires the encoding information and positioning data. Based on the acquired positioning data, it calculates the position coordinates of the photovoltaic module in the view coordinate system and marks these position coordinates in the view coordinate system, resulting in the following... Figure 5 The coordinates of each photovoltaic module are marked in the view coordinate system shown. The distribution of these coordinate points is as follows: Figure 2 The layout of the photovoltaic modules shown is consistent.

[0062] Step S303: Associate the location coordinates and coding information of each photovoltaic module to construct a location view.

[0063] Figure 6 This is a schematic diagram illustrating the correspondence between the layout of photovoltaic modules and the position view in the photovoltaic module position view generation method according to an embodiment of the present invention, as shown below. Figure 6 As shown, according to the method for generating a position view of a photovoltaic module according to the present invention, by Figure 6 The layout of the photovoltaic modules on the left side is obtained Figure 6 The image on the right shows the location of the photovoltaic (PV) modules. The location coordinates and coding information of each PV module are associated in the view coordinate system. Based on the location coordinates of the PV modules in the view coordinate system, combined with the associated coding information, an image of the location view is generated. The distribution of PV modules in the location view and the relative positions of each PV module are consistent with the actual layout of the PV modules.

[0064] The method for generating a position view of a photovoltaic module provided in this invention determines the origin of the view coordinate system based on the positioning data of the first photovoltaic module obtained by the scanning device. It also determines the relative position direction of the second photovoltaic module relative to the first photovoltaic module based on the positioning data of the first and second photovoltaic modules obtained by the scanning device, and uses this relative position direction as the first coordinate direction of the view coordinate system. The view coordinate system is constructed based on the origin and the first coordinate direction, thus establishing a view coordinate system based on the actual distribution of photovoltaic modules in the photovoltaic power station. Furthermore, for each photovoltaic module, the position offset of the photovoltaic module relative to the previous photovoltaic module is determined based on the positioning data of the photovoltaic module and the previous photovoltaic module. Finally, the position coordinates of the photovoltaic module are determined based on the position coordinates of the previous photovoltaic module and the position offset. Therefore, the position coordinates of the photovoltaic module in the view coordinate system can be determined simultaneously with the acquisition of the photovoltaic module's positioning data, thereby synchronously generating a position view of the photovoltaic module during the scanning process of the photovoltaic module by the scanning device, improving the generation efficiency of the position view. Meanwhile, an inertial navigation system and a satellite navigation system are used to acquire first and second positioning data, respectively. By combining the first and second positioning data, the position of each photovoltaic module is accurately determined, thereby improving the accuracy of the position view.
