The project deployed BE190Pro multi-protocol edge I/O modules as the core infrastructure, building a three-tier smart architecture:
Multi-Protocol Conversion: 4 isolated RS485 ports for simultaneous connectivity to:
PV systems (ABB inverter Modbus RTU → IEC104 conversion)
Battery storage (BYD BMS CAN protocol → IEC104 conversion)
Power distribution (native IEC104 support for NARI protection devices)
Industrial Reliability:
Passed 85°C continuous operation test (GB/T 2423.2)
2KVrms electrical isolation to withstand substation EMI
Edge Computing: BE190Pro modules at 3 energy substations enabled:
PV anti-backfeed protection (via Y31 analog input current direction monitoring)
Battery SOC balancing (using Y51 RTD module for temperature data)
Fault waveform capture (Y95 pulse counting for microgrid frequency analysis)
Data Fusion: Dual Ethernet ports transmitted IEC104 data to the energy management platform for:
Digital twin visualization (GIS-integrated real-time monitoring)
Load forecasting (LSTM neural network trained on historical data)
