External Vehicle Bus Isolated Interface (IP166 reinforced isolation circuit) Supports multi-protocol train communication: MVB vehicle bus, isolated RS485 serial bus, 10/100M industrial Ethernet IP communication. Reinforced insulation separates traction high-potential side and vehicle low-voltage train bus, suppressing ground loop offset and high-voltage transient surge interference. Upload data: DC-link voltage, three-phase traction/braking current, motor winding temperature, IGBT module temperature, fault timestamp records, converter operating state. Download data: Traction enable signal, regenerative braking permission, speed limitation, maintenance mode switch, fault reset command from vehicle TCMS/VCU. Onboard Storage & Maintenance Function Onboard non-volatile Flash memory for long-term storage of fault event records, operation waveform snapshots and equipment running history data without power supply. Reserved local maintenance debug port for offline firmware download, traction parameter calibration and fault data export for maintenance analysis.
