[0048] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

The singular forms "a", "the" and "the" may also include plural forms.
[0051] Here we first explain some terms involved in this application.
[0052] Photovoltaic tracking bracket: A device used to support photovoltaic panels that can adjust the angle of the photovoltaic panels in real time according to the position of the sun so that they can always receive the maximum amount of sunlight.
[0053] As described in the background technology, in the stand-alone debugging of the tracking bracket controller, debugging efficiency and debugging methods are crucial, which will affect the preliminary debugging work and subsequent operation and maintenance work. Debugging is generally based on wired debugging and wireless debugging. Wired debugging usually uses RS232 serial port line or RS485 serial port line for cable connection debugging, and wireless debugging usually uses wifi, Bluetooth, and Lora for debugging. However, these two existing debugging methods require the participation of specific equipment, and the connection debugging steps of the equipment are relatively complicated, resulting in low debugging efficiency of photovoltaic tracking brackets.
[0054] The special application of parameter access and parameter reading based on Near Field Communication (NFC) tags can integrate this function into the debugging of the tracking bracket controller. Therefore, the present application provides a photovoltaic tracking bracket debugging method and system based on NFC.
[0055] Among them, the total number of photovoltaic tracking brackets to be debugged in the photovoltaic plant is N (N is a natural number, and N≥1).
[0056] For details, see the attached Figure 1 , Figure 1 1 is a schematic diagram of the main steps of the NFC-based photovoltaic tracking bracket debugging method according to an embodiment of the present application. For the first to Nth photovoltaic tracking brackets to be debugged, such as Figure 1 As shown, the NFC-based photovoltaic tracking bracket debugging method in the embodiment of the present application mainly includes the following steps S101 to S104.
[0057] Step S101: writing preset parameters into the NFC tag;
[0058] Step S102: obtaining the offset angle of the Nth photovoltaic tracking bracket to be debugged;
[0059] Step S103: writing the offset angle into the NFC tag;
[0060] Step S104: obtaining preset parameters and an offset angle of the photovoltaic tracking bracket to be debugged based on the NFC tag, so that the controller of the photovoltaic tracking bracket to be debugged debugs the photovoltaic tracking bracket to be debugged based on the preset parameters and the offset angle.
[0061] Based on the method described in steps S101 to S104 above, the parameters of the photovoltaic tracking bracket can be quickly written and updated to achieve batch debugging, thereby improving the early debugging efficiency and later operation and maintenance replacement speed of the photovoltaic tracking bracket. At the same time, it can reduce the participation of human parameter configuration and improve the functional stability of the photovoltaic tracking bracket.
[0062] The above steps S101 to S104 are further explained below.
[0063] In some implementations, before executing the above step S101, a blank NFC tag card on which parameters can be written may be prepared.
[0064] Furthermore, in some implementations of step S101, the preset parameters can be written into the NFC tag using a terminal device such as a PC, a mobile phone, or a tablet computer before entering the photovoltaic plant.
[0065] A photovoltaic plant usually includes multiple photovoltaic sub-arrays. From the perspective of scale and layout, the area of a photovoltaic plant is often large. In order to facilitate construction, management and optimize power generation efficiency, the entire plant will be divided into multiple photovoltaic sub-arrays. Each photovoltaic sub-array includes multiple photovoltaic tracking brackets, and each photovoltaic sub-array can independently monitor, control and maintain power generation data.
[0066] Furthermore, the preset parameters of the multiple photovoltaic tracking brackets in each photovoltaic sub-array may be the same, and the preset parameters may ensure the normal operation of the photovoltaic tracking brackets.
[0067] In some implementations, the N photovoltaic tracking brackets to be debugged may be in the same photovoltaic sub-array or in multiple photovoltaic sub-arrays.
[0068] Furthermore, when the N photovoltaic tracking brackets to be debugged are in the same photovoltaic sub-array, their preset parameters are the same; when the N photovoltaic tracking brackets to be debugged are in multiple photovoltaic sub-arrays, their preset parameters are different.
[0069] Specifically, the preset parameters may include the ID number of the NFC tag, as well as the longitude and latitude, time zone, component parameters, protection parameters and wireless parameters of the photovoltaic tracking bracket to be debugged.
[0070] Among them, the initial ID number of the NFC tag in the preset parameters defaults to 1.
[0071] Latitude and longitude are the coordinate information of the geographical location of the photovoltaic tracking bracket, which accurately determines the position of the photovoltaic tracking bracket on the earth's surface.
[0072] The time zone reflects the time difference between the area where the photovoltaic tracking bracket is located and the Coordinated Universal Time (UTC). The earth is divided into different time zones, and each time zone has its own specific standard time.
[0073] The module parameters include various characteristic parameters related to the photovoltaic modules, such as at least one of the module width, array spacing (the distance between two rows of photovoltaic tracking brackets) and slope (including east slope, west slope, etc.).
[0074] The protection parameters are set to ensure the safety of the photovoltaic tracking bracket under various environmental conditions and operating conditions, and include at least one of the strong wind protection angle, snow protection angle, hail protection angle and communication failure protection angle.
[0075] Wireless parameters involve the settings of the photovoltaic tracking bracket in wireless communication, and may specifically include at least one of a communication channel, a communication address, and an air rate.
[0076] It should be noted that the above examples of preset parameters written into NFC tags are only for illustrative purposes. In practical applications, those skilled in the art can set them according to specific scenarios and requirements. In addition, the preset parameters of multiple photovoltaic sub-arrays in a photovoltaic plant can be fixed parameters or differentiated parameters. When the preset parameters are differentiated parameters, the preset parameters of each photovoltaic sub-array can be written into the NFC tag before entering each photovoltaic sub-array, which is not limited here.
[0077] Furthermore, the commissioning personnel can carry the NFC tag with the preset parameters written into it into the photovoltaic plant to start commissioning.
[0078] The above is a further description of step S101. The following is a further description of step S102.
[0079] In some implementations of the above step S102, it is necessary to obtain the offset angle of each photovoltaic tracking bracket in the N photovoltaic tracking brackets to be debugged respectively, and the offset angle can correct the difference of the inclinometer inside the photovoltaic tracking bracket.
[0080] Specifically, step S102 may include the following steps S1021 to S1022:
[0081] Step S1021: inserting the NFC tag into the calibration device;
[0082] The calibration device consists of a self-powered power supply, an inclinometer, a single-chip microcomputer, and an NFC reader / writer. The calibration device can read the current angle of the photovoltaic tracking bracket and write the current angle into the NFC tag as an offset angle.
[0083] Further, the calibration device can be set to zero degree calibration or non-zero degree calibration.
[0084] When debugging a photovoltaic tracking bracket, it is common to choose zero degrees as the calibration point. This is because this setting is easy to understand and operate, and can provide a clear and unified starting reference. Under this reference, both single-axis and dual-axis photovoltaic tracking brackets can be accurately adjusted from zero degrees based on the real-time position of the sun.
[0085] However, in certain specific geographical environments, photovoltaic power station layouts or system design requirements, non-zero degrees may be selected as the calibration degree. For example, in some high-latitude areas, the solar altitude angle is low in winter. In order to allow photovoltaic panels to better receive sunlight in winter, the calibration angle can be set to a non-zero fixed value, so that the photovoltaic panels have an initial tilt angle that is conducive to winter lighting. In addition, when there is special terrain or building obstruction in the photovoltaic power station, in order to avoid obstruction and optimize lighting, the calibration device also needs to be set to a non-zero calibration degree.
[0086] Step S1022: placing the calibration device on the Nth photovoltaic tracking bracket to be debugged, and obtaining the offset angle of the Nth photovoltaic tracking bracket to be debugged.
[0087] It should be pointed out that among the N photovoltaic tracking brackets, the offset angle of each photovoltaic tracking bracket may be different. Therefore, before debugging each photovoltaic tracking bracket, it is necessary to obtain the offset angle of the photovoltaic tracking bracket to be debugged through a calibration device.
[0088] In addition, if the photovoltaic tracking bracket itself is provided with a calibration device, there is no need to obtain the offset angle through an additional calibration device. If the photovoltaic tracking bracket is not provided with a calibration device, the offset angle can be obtained through an additional calibration device, which is not limited here.
[0089] The above is a further description of step S102. The following is a further description of step S103.
[0090] In some implementations of step S103, the NFC tag can be inserted into the calibration device, the calibration device is placed close to the crossbeam of the photovoltaic tracking bracket, and then the calibration device is turned on, and the current offset angle of the photovoltaic tracking bracket is written into the NFC tag for pre-storage. After storage, the NFC tag can be pulled out.
[0091] In some implementations of step S104, the NFC tag may be placed close to the controller (Tracker control unit, TCU) of the Nth photovoltaic tracking bracket to be debugged, so that the TCU reads preset parameters and offset angles, and debugs the photovoltaic tracking bracket to be debugged based on the preset parameters and offset angles.
[0092] Through short-range wireless communication technology, you only need to place the NFC tag close to the TCU of the photovoltaic tracking bracket to be debugged to quickly establish communication with the TCU and realize data transmission. Compared with the traditional wired connection method, NFC tags do not require cumbersome wiring and interface docking, saving debugging time and improving work efficiency. In large photovoltaic stations, there may be hundreds or thousands of photovoltaic tracking brackets that need to be debugged, so this convenience is particularly important.
[0093] In addition, the data transmission process through NFC is relatively stable and less affected by external interference. As long as the distance between the NFC tag and the TCU is close enough, the preset parameters and offset angles can be accurately read by the TCU, avoiding debugging problems caused by data transmission errors.
[0094] At the same time, since the short-range wireless communication technology requires the distance between the NFC tag and the reading device to be very close, generally within a few centimeters, in actual operation, the commissioning personnel are usually required to accurately place the NFC tag close to the TCU to complete the data transmission.
[0095] Furthermore, after the TCU reads the preset parameters and the offset angle, the ID number of the NFC tag is updated.
[0096] Specifically, the ID number of the NFC tag can be increased by 1 through the TCU to update the ID number, so as to continue to debug the next photovoltaic tracking bracket.
[0097] Among them, the TCU can be composed of a power supply, a motor drive device, and a battery. Its function is to read the preset parameters and offset angle in the NFC tag, and add 1 to the ID number in the NFC tag to distinguish multiple photovoltaic tracking brackets. Some TCUs can also include an inclinometer and obtain the offset angle through the inclinometer, which is not limited here.
[0098] Furthermore, it can be determined whether the photovoltaic tracking bracket to be debugged is the last photovoltaic tracking bracket to be debugged.
[0099] In some implementations, it may be determined whether the ID number of the NFC tag acquired by the photovoltaic tracking bracket to be debugged is N.
[0100] Wherein, N is the total number of photovoltaic tracking brackets in the photovoltaic plant, such as 150. When the ID number of the NFC tag is N, it can be determined that the photovoltaic tracking bracket to be debugged is the last photovoltaic tracking bracket to be debugged.
[0101] In some implementations, it is also possible to manually determine whether the photovoltaic tracking bracket currently being debugged is the last photovoltaic tracking bracket in the photovoltaic plant area, which is not limited here.
[0102] Further, if the photovoltaic tracking bracket to be debugged is the last photovoltaic tracking bracket to be debugged, the debugging is completed. If the photovoltaic tracking bracket to be debugged is not the last photovoltaic tracking bracket to be debugged, steps S102 to S104 are repeated until the debugging of all photovoltaic tracking brackets in the photovoltaic plant is completed.
[0103] The above is a further explanation of step S104.
[0104] In some embodiments, see Appendix Figure 2 , Figure 2 FIG. 1 is a flow chart of the main steps of a photovoltaic tracking bracket debugging method based on NFC according to another embodiment of the present application. Figure 2 As shown, it mainly includes the following steps S201 to S204.
[0105] Step S201: writing preset parameters into the NFC tag;
[0106] Step S202: obtaining the offset angle of the Nth photovoltaic tracking bracket to be debugged based on the calibration device, and writing the offset angle into the NFC tag;
[0107] Step S203: The NFC tag is placed close to the TCU of the photovoltaic tracking bracket to be debugged, so that the TCU reads the preset parameters and offset angle, and increases the ID number in the NFC tag by 1;
[0108] Step S204: determining whether the ID number of the NFC tag obtained by the photovoltaic tracking bracket to be debugged is N;
[0109] Further, if not, return to step S202; if so, the debugging is completed.
[0110] In some embodiments, see Appendix Figure 3 , Figure 3 The present invention is a data flow diagram of an NFC tag in a photovoltaic tracking bracket debugging method based on NFC according to an embodiment of the present application.
[0111] like Figure 3 As shown, the preset parameters can be written into the NFC tag through the terminal device, and the offset angle of the photovoltaic tracking bracket to be debugged can be written into the NFC tag through the calibration device;
[0112] Furthermore, the preset parameters and offset angle in the NFC tag can be written into the TCU of the photovoltaic tracking bracket to be debugged, and the ID number in the NFC tag is increased by 1 through the TCU to debug the next photovoltaic tracking bracket.
[0113] The above is a description of the NFC-based photovoltaic tracking bracket debugging method provided in this application.
[0114] Through the above implementation, the parameters of the photovoltaic tracking bracket can be quickly written and updated, batch debugging can be achieved, the early debugging efficiency of the photovoltaic tracking bracket and the later operation and maintenance replacement speed can be improved, and at the same time, the participation of human parameter configuration can be reduced, and the functional stability of the photovoltaic tracking bracket can be improved.
[0115] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art can understand that in order to achieve the effect of the present application, different steps do not have to be executed in such an order. They can be executed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present application.
[0116] Furthermore, the present application also provides a photovoltaic tracking bracket debugging system based on NFC.
[0117] See attached Figure 4 , Figure 4 FIG. 1 is a main structural block diagram of a photovoltaic tracking bracket debugging system based on NFC according to an embodiment of the present application. Figure 4 As shown, the photovoltaic tracking bracket debugging system based on NFC in the embodiment of the present application mainly includes a first writing module 401, a calibration device 402, a second writing module 403 and a debugging module 404.
[0118] In some embodiments, the first writing module 401 may be configured to write preset parameters into an NFC tag. The calibration device 402 may be configured to obtain the offset angle of the photovoltaic tracking bracket to be debugged. The second writing module 403 may be configured to write the offset angle into the NFC tag. The debugging module 404 may be configured to obtain the preset parameters and the offset angle of the photovoltaic tracking bracket to be debugged based on the NFC tag, so that the controller of the photovoltaic tracking bracket to be debugged debugs the photovoltaic tracking bracket to be debugged based on the preset parameters and the offset angle.
[0119] In some implementations, the description of the specific implementation functions can refer to steps S101 to S104.
[0120] In some implementations, the calibration device 402 may include a power supply, an inclinometer, a single-chip microcomputer, and an NFC reader / writer.
[0121] Further, it should be understood that since the setting of each device module is only for illustrating the functional units of the device of the present application, the physical devices corresponding to these modules can be the processor itself, or a part of the software in the processor, a part of the hardware, or a part of the combination of software and hardware. Therefore, the number of each module in the figure is only schematic.
[0122] It is understood by those skilled in the art that each device or module in the system can be adaptively split or merged. Such splitting or merging of specific devices or modules will not cause the technical solution to deviate from the principle of this application, and therefore, the technical solutions after splitting or merging will fall within the protection scope of this application.
[0123] The NFC-based photovoltaic tracking bracket debugging system is used to perform Figure 1 The embodiment of the photovoltaic tracking bracket debugging method based on NFC is shown, and the technical principles, technical problems solved and technical effects produced are similar. Technical personnel in this technical field can clearly understand that for the convenience and conciseness of description, the specific working process and related instructions of the photovoltaic tracking bracket debugging system based on NFC can refer to the contents described in the embodiment of the photovoltaic tracking bracket debugging method based on NFC, which will not be repeated here.
[0124] So far, the technical solution of the present application has been described in conjunction with an embodiment shown in the accompanying drawings, but it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Without departing from the principles of the present application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present application.
