RK3568/RK3588-Based Power Gateway with Fully Isolated Serial Ports and Multi-Power Protocol Access for Monitoring and O&M of New Energy Power Stations (Solar PV, Wind Power, etc.)

Driven by the "Dual Carbon" strategy, the scale of distributed photovoltaic (PV) applications continues to expand. Efficient, stable, and intelligent operation and maintenance (O&M) management is crucial for ensuring both revenue and safety.

RK3568 Version:

·Wide Operating Temperature Range (-20°C ~ 70°C): Easily handles harsh environments such as outdoor cabinets and rooftops, ensuring 24/7 uninterrupted data acquisition.

·4 Isolated Serial Ports (RS232/485 optional, with isolation)****: Flexibly adapts to Modbus RTU/Modbus TCP protocols of various inverter brands, as well as serial communication for smart meters and temperature/humidity sensors.

**·**4 Isolated Digital Inputs (DI): Accurately collects critical switch signals, such as combiner box circuit breaker status and access control switch signals.

**·**2 Isolated Digital Outputs (DO): Enables remote control (e.g., starting/stopping ventilation equipment, emergency disconnection of faulty equipment).

**·**2 Gigabit Ethernet Ports: Provides high-speed, redundant wired data backhaul channels. Optional 4G/5G modules perfectly address network coverage challenges at remote sites.

Key Application Value: The rich interface design easily connects to various inverter models and sensors, supports security camera integration, with 4 DI channels for real-time monitoring of combiner box status. Dual network ports ensure stable data transmission even in humid and salt spray environments. After deployment, the data acquisition completeness rate significantly improved, laying a solid foundation for subsequent analysis.

RK3588 Model:

·6 TOPs Flagship AI Computing Power: Enables localized processing of data streams from hundreds of devices and real-time execution of AI diagnostic algorithms (e.g., solar module hot spot detection).

·6 Isolated Serial Ports: Simultaneously connects to multiple inverter clusters, high-precision weather stations, and smart meter groups, compatible with protocols like Modbus/IEC 104.

·16 Isolated DI/DO Channels: Provides comprehensive monitoring of switch status chains in power distribution cabinets (DI high-level trigger) and remote control of ventilation/dehumidification equipment (DO high-level conduction).

·2 Isolated CAN Channels: Millisecond-level response to energy storage system PCS and tracker control commands.

·8-Channel 1080P Video Input Capability (MIPI+USB expansion): Real-time analysis of infrared video streams via NPU to accurately identify module defects and security risks.

·Dual Gigabit Ethernet Ports + 9~36V Wide Voltage Input: Ensures high-bandwidth data backhaul and adapts to voltage fluctuation scenarios in PV power stations.

Key Application Value: Integrates 3 centralized inverter clusters via 6 serial ports; 16 DI/DO channels provide full coverage for 32 switch states in the power distribution room; dual CAN bus achieves millisecond-level response for energy storage PCS commands. It can simultaneously connect to 8 security cameras and further integrate infrared cameras via 8 MIPI interfaces. Leveraging the 6 TOPs NPU, it performs real-time analysis of hot spot risks across 40,000 m² of module area (97.2% recognition accuracy), significantly reducing annual power generation loss.
