Project description
Overview This patent describes a communication system for distributed nuclear power equipment where external devices speak CAN (serial bus) while internal plant systems use Ethernet. The core approach is to place an MCU between the two domains to parse, normalize, and forward data bidirectionally, while adding electrical isolation to improve robustness in harsh environments. Main Content image generated by gpt The system defines two data paths: External-to-internal: CAN-received external data is parsed by the MCU into “first analysis data,” then forwarded over Ethernet to the central…
