The Research Of Internet-based Remote Monitoring System Of Marine Engine Room

The thesis designed the internet-based Remote Monitoring System of Marine Engine Room.Firstly, the thesis analyse the development and present situation of the monitoring system of marine engine room. Furthermore the author study the technology of the internet-based distributed monitoring and control net system and the ship-shore satellite communication in-depth. Finally, based on the technology of the Fieldbus. internet and ship-shore satellite communication, the author devised and developed the internet-based Remote Monitoring System of Marine Engine Room. The system is composed of the nautical control system of engine room , onshore remote monitoring system of engine room and ship-shore communication system.On the basis of Can bus and Ethernet of ships. The author constructed a communication network for ship. By the tools of MCGS (Monitor Control Generated System) and Visual Basic, the writer developed a monitoring and control system of engine room, which combined the control system with management system in engine room.By the application of Inmarsat-C E-mail and Internet E-mail, and Visual C++. the writer developed the subsystems of nautical communication and onshore communication, which realized ship-shore information sharing.Onshore remote monitoring system of engine room is developed by Visual Basic and Visual InterDev. and the database of this system is constructed by Microsoft SQL Server 2000. By the application of ASR ADO and ActiveX technology, the remote experts and equipment manufacturer could instruct the action of crew onboard through the internet. At the same time, this system provides data and network flat for remote fault diagnosis and expert system, and it is also the foundation of shore-board control/management integration.Proved by theory and application, the construction of Internet-based Remote Monitoring System of Marine Engine Room is a advanced technology, which interlink the monitoring system onboard and the management system onshore. This is also the trend of shore-board integration.
