[0032] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0033] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] In an exemplary embodiment, Figure 1 As shown, a photovoltaic cell monitoring and management system is provided. Multiple photovoltaic cell monitoring and management systems form a photovoltaic block local area network. Each photovoltaic cell monitoring and management system is used to manage a block of a solar photovoltaic array. Blockchain technology is used for distributed accounting. All blocks constitute a solar photovoltaic array. The photovoltaic cell monitoring and management system includes: a controller, a storage module, a data reading and writing module, an interface module, an input and display module, a Beidou / GPS positioning module, a camera module, a detection module, a wireless communication module, and a power module.

[0035] The data reading and writing module, Beidou / GPS positioning module, shooting module, detection module and wireless communication module are all connected to the interface module; the controller is connected to the interface module, input display module and storage module;

[0036] The detection module is used to detect the photovoltaic power, power generation and light intensity of the photovoltaic cells in the corresponding block area;

[0037] The wireless communication module and the data reading and writing module are respectively used to obtain power generation fee management information;

[0038] Specifically, the wireless communication module and data reading and writing module will obtain electricity prices and cash flows from various operations into the electronic wallet, making the block managed by this application an independent capital product. By averaging the area, smaller investment units with operating cash flow, predictable returns, and precise management will be formed, attracting different investors and expanding the source of photovoltaic construction funds.

[0039] The input display module is used to obtain maintenance personnel inspection reports and maintenance logs, various business conditions, instructions from superiors and fellow households, and the total area of ​​photovoltaic cells in the block;

[0040] The shooting module is used to obtain environmental photos and business photos of the block area; that is, to shoot the real scene of the block site, environmental improvement, and diversified operations, and to understand the relationship between sandstorms, snow, freezing rain, haze and power generation;

[0041] The BeiDou / GPS positioning module is used to obtain the location information of photovoltaic cells within a given area. This location information allows managers and investment analysts to clearly and intuitively understand the performance of photovoltaic power generation and operations within the block on a geographic information system (GIS). The BeiDou / GPS positioning module uses the BeiDou / GPS dual-mode global satellite positioning system to obtain the block location and transmits the location information along with the data file, enabling managers and investors to understand the block's location. Accurately positioned photovoltaic arrays provide a geographic operational reference for the layout of photovoltaic power generation belts. Countries along the route can coordinate international power grid scheduling based on time and power generation patterns, mitigating the risk of power grid fluctuations.

[0042] The controller is used to determine the power generation price, land assessment price, investment-output benefit, and normalized photovoltaic block value of the basic unit of the block according to the photovoltaic cell's photovoltaic power generation power, power generation, light intensity, power generation fee management information, maintenance personnel inspection report and maintenance log, diversified business conditions, superior and same-household instructions, the total area of ​​photovoltaic cells in the block, environmental photos, business photos of the block, location information, electronic wallet address and amount, and send them to the storage module for storage; the normalized photovoltaic block value of the basic unit of the block is the photovoltaic operation basic unit obtained by dividing the total input industry and investment-output benefit after weighted average by the total area of ​​photovoltaic cells in the block; the photovoltaic block value adopts a weighted statistical method, and the power generation of the block, the purchase price of the local consumption of the electricity price, the light pattern, the carbon emission trading income, the diversified business income, the land price appreciation income, and the environmental protection income of the block are calculated and marked using internationally recognized accounting standards, specifically: D=(A1B1+A2B2+A3B3+.....A n B n ) / S; where D is the value of the photovoltaic block, S is the total area of ​​photovoltaic cells in the block, and A n For each income item, B n The controller uses a pre-set program to read the total power generation, total power generation value, and total revenue from diversified operations for a specific time period. It then calculates the total revenue and input-to-industry ratio for the standard block during that time period. Based on the pre-set weights, the controller then calculates the overall price of the standard block. This comprehensive value includes the input-output ratio, the land value after environmental assessment, and the income, maintenance, and management benefits of diversified operations. Scores above 90 are considered excellent, 60-90 are considered average, and 60 is considered inferior. This data is organized into dynamic tables for operational and investment analysis. Diversified operations and maintenance are logged for assessment purposes. Environmental photos are stored for environmental assessment and land pricing purposes. This data is also provided for review by diversified operations assessment personnel and relevant personnel.

[0043] The storage module is used to store information transmitted by the controller, and is also used to store electronic wallet addresses and amounts, clock date information, management instructions and operation management programs.

[0044] In order to further improve the accuracy of management, the storage module is also used to store photos of lighting conditions, environmental landscapes, photos of various operations, real-time electricity charges, carbon emission trading fees, various operations income and land prices, and other data; the storage module is also used to store the overall income value of the block, making it easier for all parties to understand;

[0045] The detection module includes: an analog-to-digital conversion circuit and a sensor group;

[0046] The sensor group is used to detect the photovoltaic power generation power, power generation and light intensity of the photovoltaic cells in the block area; wherein the dynamic power generation power and cumulative power generation are obtained based on the time integration of the voltage and current obtained by the voltage and current sensors.

[0047] The analog-to-digital conversion circuit is connected to the sensor group and the interface module respectively, and is used to perform analog-to-digital conversion on the light power, power generation and light intensity detected by the sensor group.

[0048] The input display module includes: a capacitive sensing display screen and a touch soft keyboard.

[0049] As a specific embodiment, the input display module inputs various operating income, inspection and maintenance logs, reads and writes environmental information, photos, electricity charges, etc., so that all parties can comprehensively grasp the situation, accurately conduct investment environmental impact assessments, input-output valuations, and the local support for new energy, etc., especially when connecting with large-scale, new energy financial products, which require such precise management, evaluation and policy implementation.

[0050] The interface module is a MicroUSB interface, a USB interface or a Type-C interface, which converts the data transmitted from each module into data that can be operated by the controller through half-line / parallel operation or level adaptation operation.

[0051] The controller uses an FPGA chip, which is responsible for the application's operational operations, log management, data input / output, e-wallet management, photovoltaic power and sunlight detection and analysis, environmental photography, wireless communication network transmission control, and other functions. The FPGA chip is infinitely reprogrammable, and loading a new program takes only a few hundred milliseconds. The FPGA chip uses partial reconfiguration technology, which not only facilitates program modification but also reduces hardware overhead. Specifically, the controller obtains detected photovoltaic power generation current, voltage, and illumination information, converting inspection report information and various business information input through the input display module with electricity cost information obtained through the wireless communication module or data read / write module. This allows for the management of wallet cash flow, making the application a relatively independent power generation operation unit. It normalizes and standardizes the classification and division of photovoltaic power generation arrays and monitors investment and output, making the photovoltaic power generation industry a highly liquid capital product, which is beneficial to the large-scale promotion of photovoltaic construction.

[0052] The random dynamic information processed and calculated by the controller is stored in the controller's internal storage module. This random dynamic information includes intermediate calculation results, clock information, and other information. The storage module is the EEPROM (Electrically Erasable Yorogremmable Readonly Memory) memory. The EEPROM memory contains information that cannot be lost after power is removed from the running program, such as photovoltaic power generation logs, operating totals, and stack information.

[0053] EEProm memory is a plug-and-play storage component that maintains data even after power failure. The storage module is used to store PV operation information, e-wallet addresses and balances, various business information, environmental assessments and land price information, carbon emissions trading information, and computational data. This information is divided into raw data, such as current and voltage parameters, and computational results, such as comprehensive input-output information and rating information. Compared to traditional tiered investment products such as bonds, PV Manager operators and investors can not only make simple decisions based on ratings, but also view real-time reports and comprehensive calculation results. They can also directly access field logs, e-wallets, and various real-world scenarios, and even develop their own analytical models. This provides a powerful tool for minimizing PV investment risks and steadily and proactively promoting PV construction.

[0054] As a specific embodiment, the wireless communication module includes: a 3G / 4G / 5G communication unit, a wireless local area network (WLAN), and a satellite communication unit. In areas with good 3G / 4G / 5G public communication environments, each wireless communication module independently accesses the public network for communication. In areas with poor public communication environments, the wireless communication module is divided into a central station and slave stations. The central station and the slave stations communicate via the wireless local area network (WLAN), aggregating information from each slave station and uploading it uniformly through the central station's satellite channel, thus saving satellite communication fees.

[0055] The data reading and writing module is used to obtain power generation fee management information through a USB flash drive and manage the cash flow of the electronic wallet; the electronic wallet uses wireless electronic transfer to collect and pay various fees according to rules, so that economic benefits are directly linked to management and operation benefits.

[0056] Data from areas with poor communication conditions can be imported regularly via USB flash drives.

[0057] As a specific embodiment, the data read / write module includes a data read / write interface and a protocol conversion circuit. One end of the protocol conversion circuit is electrically connected to the data read / write interface, and the other end of the protocol conversion circuit is electrically connected to the interface module. The data read / write interface is a MicroUSB interface, a USB interface, or a Type-C interface. In this embodiment, the USB interface is used for offline transmission of various photovoltaic operation information. The content transmitted is the same as that transmitted wirelessly, and the two serve as backups for each other to improve the robustness of this application.

[0058] The camera module includes a wide-angle lens with a large depth of field and a photoelectric imaging encoder. It can be used to capture images in real time or at a specific time, without manual focusing, allowing operators, investors, and tourists to understand the maintenance, diversified operations, and environmental management status of photovoltaic arrays.

[0059] The power module includes a device that converts DC voltages to 5V, 3V, and 2.5V operating voltages. Furthermore, the power module includes a photovoltaic charging voltage-stabilized input interface, a lithium battery, and a DC-converting voltage-stabilized power supply. One end of the power module is electrically connected to the photovoltaic power output interface. The module charges the lithium battery through the photovoltaic charging voltage-stabilized input interface and supplies power to the application through the DC-converting voltage-stabilized power supply. At night or when photovoltaic power generation is insufficient, the lithium battery supplies power to the application through the DC-converting voltage-stabilized power supply.

[0060] This application realizes the precise management of photovoltaic power generation through block-based and normalized detection and operation, which is beneficial to improving the economic benefits of photovoltaic design, construction and operation; it is beneficial to improving the management level; through the calculation of photovoltaic standard blocks, normalized photovoltaic standard investment products are obtained, which is beneficial to decomposing large-scale photovoltaic investments into standardized small-scale investment products, lowering the investment threshold, and providing complete and accurate information, which can eliminate information asymmetry and investment risks in photovoltaic investments, and facilitate the participation of small and medium-sized investors; standardizing photovoltaic capital products is beneficial to the securitization and liquidity of accumulated photovoltaic large-scale investments, which is beneficial to photovoltaic investment construction.

[0061] Solar photovoltaic array blocks are deployed centered around blocks with satellite communication capabilities. The deployment depends on the array's installation environment, investment level, management methods, and various operating conditions. After installation, the total area of ​​the photovoltaic panels, the operating environment, various operating projects, and initial environmental photos are required to submit this application. The specific workflow is as follows:

[0062] S1, power on;

[0063] S2, based on the data obtained by the detection module, determines whether power generation can be normal and whether the electricity bill can be received in time;

[0064] S3, input various business project information and photos, and environmental photos;

[0065] S4, setting the dynamic calculation cycle of the electronic wallet, including the settlement frequency of income and expenditure such as electricity charges, electricity consumption, and multiple operations, such as hourly, daily, and monthly;

[0066] S5, enter the daily working cycle. If the light intensity is normal, but the power output decreases, a fault alarm will be given;

[0067] S6. If there is income from multiple operations, such as income from the sale of poultry eggs, fish, mushrooms, etc., the income from the operations should be entered into this application; diversified operations are closely related to managers. After this application converts photovoltaics into financial investment products, the resulting cash flow will be amplified through financial products, promoting diversified operations of photovoltaic investment companies and managers, and enhancing the enthusiasm for photovoltaic diversified operations cash flow.

[0068] S7, the administrator enters the log when performing dust removal, snow removal, inspection, and multiple operations.

[0069] S8, based on weighted statistics of local photovoltaic electricity prices, power generation efficiency, diversified operations and other income, divides photovoltaic blocks into superior, ordinary and inferior products; and obtains the block efficiency of photovoltaic arrays per square meter, which not only promotes the improvement of photovoltaic efficiency, but also subdivides the financial capital of photovoltaic investment to each square meter, forming a refined photovoltaic capital basic product with sufficient information disclosure and low investment threshold.

[0070] S9, after processing S1-S8, decomposes the original relatively extensive photovoltaic power generation array into photovoltaic capital basic products with accurate quantified prices. The cash flow generated by it can be accurately calculated, which is beneficial for international financial capital to shift towards new energy investment.

[0071] The standard photovoltaic capital products formed by S1-S9 above can be used as the basic unit for listed loan-collateralized risk swaps and futures hedging, mobilizing accumulated photovoltaic assets. The electronic wallet is linked to a bank account, creating a precise, independent accounting unit, which will help photovoltaics become an industry accessible to mass investment and entrepreneurship.

[0072] like Figure 2 As shown, this application provides another workflow, which specifically includes:

[0073] S101, power on;

[0074] Manual startup and automatic restart after a long power outage are equivalent. The program will form a program breakpoint stack protection before shutting down, and various working status data will be pushed into the stack and stored in EEpRom, and will not be lost due to power outage.

[0075] S102 determines that the shutdown or power failure ends the breakpoint, and after the program is started, it automatically restores the stack search data and restarts the program.

[0076] The system clock is powered by its own quartz crystal oscillator module and dedicated clock battery, and is not affected by shutdown and power failure, so the system will automatically restore to the last working state, but the clock is synchronized with the standard Beijing time, which does not affect the operation of the present invention.

[0077] S103, the controller uses polling to read data from the detection module; because the power generation power and light intensity changes have a strong autocorrelation, a polling time of less than 300ms can meet the detection requirements.

[0078] S104, the controller uses an interrupt trigger method to read the data of the wireless communication transmission module, the display input module, the clock, and the Beidou / GPS signal to ensure timely acquisition of information.

[0079] S105: The controller calculates the power generation benefit in a cyclic manner and updates the electronic wallet data.

[0080] S106, before shutting down or powering off, the program pushes the current detection data, logs, and program breakpoints into the stack.

[0081] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] This document uses specific examples to illustrate the principles and implementation methods of this application. The description of the above examples is only intended to help understand the method and core concept of this application. At the same time, for those skilled in the art, based on the concept of this application, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting this application.
