Research on Local Area Network of Marine Gas Turbine Distributed Control System

Characteristics and requirements of marine gas turbine distributed control system(DCS) were introduced in this paper. CAN-bus was used as the field bus of marine gas turbine DCS. Semi-physical simulation platform of gas turbine DCS local area network(LAN) which included multi-smart devices was established. The networking technologies of many smart devices based on the CAN bus were studied which included the application layer data communication protocol design, system interface programming, network delay analysis, network load characteristics analysis, etc.. The semi-physical simulation test was conducted in a real network environment.
