[0050] The main control unit 100 is connected to the NFC module 200 via a connecting cable. The main control unit 100 communicates with the NFC module 200, for example, via the I2C or SPI bus protocol.

[0051] The NFC module 200 communicates with the reader / writer to perform interactive synchronization of the identity information and status information, wherein the status information includes at least one of the production status information, packaging status information and transportation status information of the photovoltaic equipment 10.

[0052] The reading and writing device is, for example, an NFC reading and writing device or a terminal that includes an NFC reading and writing device, such as a handheld terminal.

[0053] The specific interaction process between the NFC module 200 and the main control unit 100 is as follows:

[0054] During the unpowered phase of photovoltaic device 10: Install an NFC module 200 on each photovoltaic device 10 to store the identity information of the photovoltaic device 10, such as device ID, model, production date and other basic information;

[0055] Photovoltaic equipment 10 power-on stage: After the photovoltaic equipment 10 is powered on, the main control unit 100 performs self-test and initialization, and starts the NFC module 200 to communicate with the main control unit 100 to ensure that production information can be read and synchronized.

[0056] Data interaction and synchronization phase: The NFC module 200 and the main control unit 100 conduct comprehensive data interaction, read identity information from the NFC module 200 and synchronize it to the main control unit 100 to ensure that the photovoltaic device 10 operates according to the debugging parameters and configuration parameters;

[0060] like Figure 2 As shown, this application embodiment provides a photovoltaic equipment 10 production management system 40 based on NFC technology. The photovoltaic equipment 10 is equipped with an NFC module 200 and a main control unit 100 communicating with the NFC module 200. The NFC module 200 stores the identity information of the photovoltaic equipment 10. The system includes: an external device 20, used to communicate with the main control unit 100 through the NFC module 200 to perform interactive synchronization of production information, the production information including at least one of the debugging information, configuration information, and test information of the photovoltaic equipment 10; a read / write device 30, used to communicate with the NFC module 200 and the management system 40 to perform interactive synchronization of the identity information and status information, the status information including at least one of the production status information, packaging status information, and transportation status information of the photovoltaic equipment 10; and a management system 40, used to store the identity information and the status information.

[0061] In some embodiments, the system further includes: production equipment for installing an NFC module 200 and a main control unit 100 communicating with the NFC module 200 in the photovoltaic equipment 10.

[0062] The production equipment first assembles the hardware of the photovoltaic device 10, including the mainboard, power module, heat dissipation system, interfaces, and main control unit 100. After the hardware assembly is completed, a functional check is performed to ensure that all components are assembled correctly and without errors.

[0063] In the design of the main board of the photovoltaic device 10, a reserved space is provided for installing the NFC module 200, and a reserved space is provided on the casing of the photovoltaic device 10 for installing the antenna. The NFC module 200 is connected to the main control unit 100 via wires or directly. The installation position of the NFC module 200 is adjusted according to the signal coverage and communication quality.

[0064] Each photovoltaic device 10 possesses unique identification information during the production process through the NFC module 200. This unique identification information can be integrated into the NFC module 200 itself or configured in the NFC module 200 via the reader / writer 30. The identification information includes, but is not limited to, basic information such as the photovoltaic device 10's device ID, model, and production date, ensuring that the photovoltaic device 10 can be uniquely identified and tracked during subsequent production and use.

[0065] The NFC module 200 uses a miniaturized PCB board, integrating NFC tags, matching circuitry, and an integrated antenna to ensure high reliability and lightweight characteristics. External protective design is required to adapt to the outdoor working environment of the photovoltaic device 10 (e.g., waterproof and dustproof treatment).

[0071] By controlling the NFC module to communicate with the management system through the reader / writer device, identity and status information are exchanged and synchronized. NFC technology is used for wireless automated data exchange, which reduces the errors that may occur in manual operation and improves the accuracy of data recording. At the same time, the status information and identity of the photovoltaic equipment can be uploaded to the management system in a timely manner, so that the photovoltaic equipment can be traced in real time at every stage of the entire production process, ensuring the traceability of the equipment and the integrity of the information.

[0072] In one example embodiment, the production information is debugging information, which includes debugging data and debugging results. The debugging data includes debugging parameters, debugging instructions, etc., and the external device is a debugging device.

[0084] S604: Control the main control unit to perform quality testing based on the test command to obtain test results, and transmit the test results to the test device through the NFC module.

[0085] Specifically, the main control unit collects various performance indicators of the photovoltaic equipment based on test commands, such as voltage, current, and frequency, and performs quality tests on each performance indicator.

[0086] Based on the above steps S602-S604, NFC technology can be used to quickly complete the testing of photovoltaic equipment, realize the testing and data collection of various performance indicators of photovoltaic equipment (such as voltage, current, frequency, etc.), and record the test results in real time to ensure that each photovoltaic device meets the quality standards.

The production status information specifically includes debugging data, debugging results, and process records, such as timestamps. The process by which the NFC module interacts and synchronizes with the management system through the reader / writer device is as follows:

[0088] The NFC module is controlled to communicate with the reading and writing device. The reading and writing device reads the identity information and production status information stored in the NFC module. After binding the identity information and production status information, the reading and writing device transmits them to the management system.

[0089] In this example embodiment, the management system stores and manages production status information. Production personnel can query the production status information of photovoltaic equipment at any time through the read / write device and upload it to the management system, further improving the accuracy of quality control.
