The Research Of CAN-based Monitoring And Control Network System Of Marine Engine Room

Firstly, based on the analysis of the structure characteristics and development trend of the monitoring and control system of marine engine room as well as an in-depth investigation of the Fieldbus technology, a new Fieldbus-based ship network system is put forward in this article. Furthermore the author has thoroughly discussed a typicalFieldbus technology------CAN (Controller Area Network) and its related problemssuch as history, performance, specification, implementation etc. Finally, combined with the actual study result of the "TongDa plan" which is initiated by the Ministry of Communications, the paper introduced a CAN-based monitoring and control system, and also described the design and implementation method of the model system in detail.It is proved by the practice of the project that the data communication of CAN has outstanding characteristics about reliability, realtime, and flexibility, therefore is very suitable for the construction of monitoring and control system of marine engine room. This research direction is adapted to the international development trend.
