[0037] First embodiment

[0038] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic structural diagram of a first embodiment of a device for photovoltaic intelligent operation and maintenance provided by the present invention; Figure 2 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 3 for Figure 1A schematic diagram of the overall three-dimensional structure of the device shown; Figure 4 for Figure 3 A device for photovoltaic intelligent operation and maintenance, comprising:

[0039] A box body 1, wherein an operating instrument main body 2 is arranged inside the box body 1;

[0040] A heat dissipation net 3, wherein the number of the heat dissipation nets 3 is two, and the two heat dissipation nets 3 are respectively arranged on the left and right sides of the surface of the box body 1;

[0041] Active components 4, the number of the active components 4 is two, and the two active components 4 are respectively arranged on the left and right sides of the surface of the box body 1 and are located on the opposite side of the two heat dissipation nets 3;

[0042] The pulling rod 5 includes two pulling rods 5 , and the two pulling rods 5 are respectively arranged between the operating instrument body 2 and the movable component 4 .

[0043] The movable assembly 4 includes two fixed rods 41 . The surfaces of the two fixed rods 41 are sleeved with movable sleeves 42 . The opposite sides of the two movable sleeves 42 are connected with L-shaped connecting rods 43 .

[0044] A movable plate 44 is connected between the two L-shaped connecting rods 43 , one end of the pulling rod 5 is connected to the movable plate 44 , and a groove 7 adapted to the pulling rod 5 is provided at the center of the side surface of the box body 1 .

[0045] The use of the fixed rod 41 and the movable sleeve 42 can drive the movable plate 44 to move up and down, and the use of the pulling rod 5 facilitates the opening and closing of the heat dissipation net 3 by driving the movable plate 44 to move up and down through the operating instrument body 2.

[0046] The top and bottom ends of the fixing rod 41 are both connected to fixing blocks 45 , and the fixing blocks 45 are connected to the surface of the box body 1 .

[0047] A box cover 6 is provided on the top of the box body 1 .

[0048] The operating device body 2 is composed of a sensor module

[0049] Current sensor: used to detect the current size in the photovoltaic system. It can measure DC current and AC current and determine the current value by sensing the magnetic field generated by the current. The accuracy and response speed of the current sensor are crucial for accurate fault diagnosis.

[0050] Voltage sensor: responsible for measuring the voltage of the photovoltaic system. Similar to the current sensor, the voltage sensor also needs to have the characteristics of high precision and fast response. It can detect DC voltage and AC voltage and provide voltage data for fault diagnosis.

[0051] Temperature sensor: monitors the temperature of photovoltaic modules and other key components. Abnormal temperature changes may be a sign of failure, such as hot spots, poor connections, etc. Temperature sensors can use contact or non-contact measurement methods.

[0052] Light sensor: measures the light intensity of the environment in which the photovoltaic system is located. The light intensity directly affects the power generation efficiency of the photovoltaic modules, so the light sensor can help determine whether the performance of the photovoltaic system is normal.

[0053] 2. Data Acquisition and Processing Module

[0054] Data collector: responsible for collecting various data from the sensor module and converting them into digital signals for processing. The data collector needs to have high-speed sampling, high-precision conversion and reliable data transmission capabilities.

[0055] Microprocessor: Analyze and process the collected data. The microprocessor usually uses a high-performance embedded chip and runs advanced data analysis algorithms and fault diagnosis programs. It can monitor and analyze the data in real time according to preset fault diagnosis rules to determine whether there is a fault.

[0056] Memory: used to store collected data and diagnostic results. Memory can be divided into volatile memory (such as RAM) and non-volatile memory (such as Flash). Volatile memory is used to temporarily store data so that the microprocessor can process it quickly; non-volatile memory is used to store data and diagnostic results for a long time for subsequent query and analysis.

[0057] 3. Communication Module

[0058] Wired communication interface: such as RS485, Ethernet, etc., is used to communicate with other devices in the photovoltaic system, such as photovoltaic inverters, data loggers, etc. Wired communication interface usually has stable and high-speed data transmission capabilities, but requires wiring, and installation and maintenance are relatively complex.

[0059] Wireless communication modules: such as Bluetooth, Wi-Fi, ZigBee, etc., are used to communicate with mobile devices (such as mobile phones, tablets) or remote servers. Wireless communication modules have the advantages of easy installation and high flexibility, but data transmission speed and stability may be affected to a certain extent.

[0060] 4. Display and operation module

[0061] Display screen: used to display diagnostic results, data charts and operation interfaces. The display screen can be a liquid crystal display (LCD) or a touch screen, so that users can intuitively understand the operating status and fault information of the photovoltaic system.

[0062] Operation button: provides an interface for users to operate the intelligent fault diagnosis instrument, such as starting diagnosis, setting parameters, querying historical records, etc. The operation button can be in the form of a physical button or a virtual button, and can be selected according to different design requirements.

[0063] The working principle of the intelligent fault diagnosis instrument is as follows:

[0064] The sensor module monitors various parameters of the photovoltaic system in real time, such as current, voltage, temperature, light intensity, etc., and transmits these data to the data acquisition and processing module. After the data acquisition module converts the analog signal into a digital signal, the microprocessor analyzes and processes the data.

[0065] The microprocessor runs advanced data analysis algorithms and fault diagnosis programs, and monitors and analyzes the collected data in real time according to preset fault diagnosis rules. For example, by comparing the difference between the actual measured value and the theoretical value, it can determine whether the photovoltaic module has short circuit, open circuit, hot spot and other faults; by analyzing the changing trends of current and voltage, it can predict the performance degradation of the photovoltaic system.

[0066] If a fault is detected, the microprocessor will display the fault information on the display screen and send the diagnosis results to the user or remote server through the communication module. The user can take corresponding maintenance measures based on the diagnosis results to restore the normal operation of the photovoltaic system.

[0067] At the same time, the intelligent fault diagnosis instrument can also store the collected data in the memory for subsequent query and analysis. Users can query historical data and analyze fault trends through operating buttons or applications on mobile devices, providing a basis for the maintenance and optimization of the photovoltaic system.

[0068] The working principle of a device for photovoltaic intelligent operation and maintenance provided by the present invention is as follows:

[0069] When in use, when protecting the heat inside the box 1, first pull the operating instrument body 2 upward to drive the pulling rod 5 to move upward, and when the pulling rod 5 moves upward, it drives the movable plate 44 to move upward. When the movable plate 44 moves upward, the movable sleeve 42 is driven by the L-shaped connecting rod 43 to move on the surface of the fixed rod 41, until the movable plate 44 opens the heat dissipation net 3, so that the external gas can be mixed and pushed with the gas inside the box 1 to discharge the heat.
