Dual-Bus Redundant Ethernet/CAN Switching for Industrial Communication

Project description

1. Overview Dual-bus redundant communication is a reliability-oriented industrial communication method that transmits the same equipment data through two independent physical paths and dynamically selects the active path based on transmission quality. In CN121841898A, industrial equipment parameters are packaged into both Ethernet data frames and CAN bus data frames, then sent in parallel to a receiver through separate communication paths. The system addresses a practical weakness in industrial control environments: Ethernet and CAN are often used together, but many existing systems still…
