[0045] The county-level dispatch automation system issues "adjustable and controllable" commands to the multi-functional remote terminals of distributed power sources. The multi-functional remote terminals decompose the adjustable and controllable commands to each circuit breaker and generator unit (inverter) and forward them to the user monitoring system, which then outputs the commands to the user monitoring system.

[0054] The power micro vertical encryption chip and the main station vertical encryption device establish an encrypted tunnel through the SM2 encryption algorithm.

[0055] In this embodiment, to address the security requirements of data transmission in photovoltaic power plants, the vertical encryption module 12 incorporates a micro vertical encryption chip for power, and establishes an encryption tunnel with the main station's vertical encryption device using the SM2 encryption algorithm (an asymmetric encryption method), ensuring the confidentiality, integrity, and availability of the data.

[0056] As a key component of the photovoltaic multi-functional remote terminal, the vertical encryption module 12 is responsible for data encryption and decryption.

[0057] The power micro-vertical encryption chip ensures the confidentiality and integrity of data. In this embodiment, the chip and the master station's vertical encryption device establish an encrypted tunnel using the SM2 encryption algorithm, achieving end-to-end encrypted data transmission.

[0058] SM2 is a public-key cryptography algorithm based on elliptic curves. It boasts advantages such as high security, low computational complexity, and small storage space. By establishing an encrypted tunnel using the SM2 encryption algorithm, all data sent from the photovoltaic multi-functional remote terminal undergoes encryption processing. Only the master station's vertical encryption device, possessing the corresponding decryption key, can decrypt and read the data. This design ensures the confidentiality of data during transmission.

[0059] According to the above embodiments, in one specific embodiment, the 5G module 15 in the above photovoltaic multi-functional remote terminal includes a SIM (Subscriber Identity Module) card slot;

[0060] The SIM card slot is used to install a SIM card, which is then used to access the 5G network.

[0061] This embodiment addresses the need for high-speed and stable communication networks in remote monitoring and management of photovoltaic power plants. The 5G module 15 of the photovoltaic multi-functional remote terminal has a built-in SIM card slot for installing a SIM card and accessing the 5G network, enabling fast and reliable data transmission.

[0062] A SIM card slot is a physical interface for installing a SIM card, which allows access to mobile communication networks.

[0063] A SIM card is a smart card that stores user identity information and network authentication information, allowing access to mobile communication networks and network services. In this embodiment, the SIM card slot supports 5G network SIM cards, enabling the photovoltaic multifunctional remote terminal to access the 5G network and achieve high-speed data transmission.

[0064] 5G networks offer extremely high transmission speeds and extremely low latency, enabling the photovoltaic multi-functional remote control terminal to transmit large amounts of data quickly and accurately. Whether it's real-time data from the photovoltaic power generation module 20, fault alarm information, or remote control commands, all can be rapidly transmitted to the target device or system via the 5G network, achieving real-time data sharing and efficient processing. The photovoltaic multi-functional remote control terminal eliminates the need for complex cabling or additional network equipment, thus reducing networking costs and maintenance complexity.

[0065] According to the above embodiments, in one specific embodiment, the photovoltaic multifunctional remote terminal further includes: a positioning module;

[0066] The positioning module acquires geographical location information and is connected to the control module 11.

[0067] This embodiment addresses the need for accurate acquisition of equipment geographical location information in photovoltaic power plants by adding a positioning module to the photovoltaic multi-functional remote terminal. This positioning module is closely connected to the control module 11 and can acquire and report the geographical location information of the photovoltaic multi-functional remote terminal in real time, providing support for the operation and maintenance management, fault location, and emergency response of the photovoltaic power plant.

[0068] Specifically, the positioning module integrates high-precision positioning technologies (such as the Global Positioning System and BeiDou satellite positioning systems), enabling it to acquire real-time geographic location information of the photovoltaic multi-functional remote terminal, including longitude, latitude, and altitude. In this embodiment, the control module 11 is connected to the positioning module via internal circuitry to receive, process, and upload geographic location information.

[0069] The positioning module receives positioning signals from satellites via its built-in satellite positioning receiver and processes them to obtain the precise geographical location information of the photovoltaic multi-functional remote control terminal. This acquired geographical location information is transmitted in real-time to the control module 11. The control module 11 formats this information to ensure compatibility with the data format of the photovoltaic power station monitoring system and prepares it for uploading to the main station or user-side monitoring system 01 via a communication network (such as a wired network, 5G network, etc.). Upon receiving the geographical location information, the main station or user-side monitoring system 01 can display the real-time location distribution of the photovoltaic multi-functional remote control terminal, providing maintenance personnel with an intuitive visual reference.

[0070] According to the above embodiments, in one specific embodiment, in the above photovoltaic multifunctional remote terminal, the antenna module 19 is a 4-in-1 antenna or a suction cup antenna.

[0071] The 4-in-1 antenna integrates the antenna functions of multiple communication frequency bands, and the suction cup antenna is attached to the outer shell.

[0072] Antenna module 19 can employ a 4-in-1 antenna or a suction cup antenna to meet communication needs in different scenarios. A 4-in-1 antenna is a device that integrates the functions of multiple communication frequency bands. It can achieve multiple frequency bands within a single physical structure, such as the communication needs of BeiDou and Global Positioning System, thereby significantly reducing the number of antennas and the space occupied. This antenna design not only improves the integration of the communication system but also helps reduce overall cost and complexity. A suction cup antenna is a type of antenna that is fixed to the housing using a suction cup. It is typically made of flexible materials to adapt to different shaped housing surfaces. The suction cup part is made of a special material with strong adsorption force, allowing it to be firmly fixed to the vehicle body surface (in this example, the housing of a photovoltaic multi-functional remote terminal). Furthermore, suction cup antennas also have advantages such as small size, light weight, and easy installation.

[0073] The choice of antenna module 19 for a photovoltaic multi-functional remote terminal should be determined based on specific needs and scenarios. If the terminal needs to support multiple communication frequency bands simultaneously and space is limited, a 4-in-1 antenna should be selected; if the terminal has high requirements for the ease of antenna installation and reception performance, a suction cup antenna should be selected.

[0074] According to the above embodiments, in one specific embodiment, the photovoltaic multifunctional remote terminal further includes: a storage module; the storage module is connected to the control module 11.

[0075] In this embodiment, a storage module is added to meet the data storage requirements of the photovoltaic multi-functional remote terminal, and it is closely connected to the control module 11.

[0076] The storage module is a key component for data storage in the photovoltaic multi-functional remote terminal. It employs non-volatile storage technologies (such as flash memory and solid-state drives) to ensure long-term data retention even in the event of a power outage. The storage module connects to the control module 11 to receive, store, and retrieve data.

[0077] The control module 11 transmits the collected photovoltaic power station operation data, fault alarm information, and remote control commands to the storage module in real time. The storage module is responsible for saving this data in a specific format and storage structure. The storage module adopts an appropriate storage strategy based on the data type and importance. For example, for data with high real-time requirements, a fast storage method can be used to ensure data timeliness; for historical or backup data, a more economical storage scheme can be used. When it is necessary to query, analyze, or transmit stored data, the control module 11 sends a read request to the storage module. The storage module quickly locates and reads the corresponding data according to the request, and then sends it back to the control module 11 for further processing.

[0078] The introduction of storage modules enables the photovoltaic multi-functional remote terminal to store important data in real time, avoiding the risk of data loss or corruption. In the event of equipment failure or network interruption, the stored data can still serve as a basis for backup or recovery. The large amount of stored data provides strong support for the operation and maintenance management, performance analysis, and optimization of photovoltaic power plants. Through data mining and analysis, potential problems in power plant operation can be identified, power generation strategies can be optimized, and the overall efficiency of the power plant can be improved.

Through its integrated communication, control, and monitoring functions, the terminal enables remote monitoring of various components within the PV power plant, data acquisition and analysis, fault diagnosis and early warning, thereby optimizing the power plant's operating status and improving power generation efficiency and energy utilization.
