Marine Main Engine Remote Control System with Redundancy CANBus Based on Distributed Processing Technology

摘要

For middle-speed and four-stroke marine diesel engine, a new Main Engine Remote Control System based on distributed processing and dual-redundant CAN network communication technology was presented. It includes engine control unit, indicating panel unit, engine safety unit, main engine interface, digital governor unit and distributed processing unit. System data can be exchanged by dual-redundant CAN network. The distributed processing unit is independent in physics completely, so it has less impact on other units when some units malfunctioned. The communication of system units is designed by open communication protocol of CAN, it can self-test and troubleshoot. The System has function of self-insurance when loss power, and can delay shut-down when loss of air. Its operating mode and man-machine interface are convenient and friendly.
