The Research Of Remote Monitoring System Of Ship Equipment Based On Heterogeneous Network

The thesis designed the heterogeneous network-based Remote Monitoring System of Ship Equipment.Firstly,the thesis analyse the development and present situation of the monitoring system of ship equipment.Furthermore the author study the technology of the heterogeneous network-based monitoring and control net system of ship equipment in-depth. Finally, based on the technology of the CANbus and WEB, the author devised and developed the heterogeneous netwok-based Remote Monitoring System of Ship Equipment. 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 Canbus and Ethernet of ships.The author constructed a communication network for ship.By the tools of Visual Basic.NET, 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 GT800 and JSP, the writer developed the subsystems of nautical communication and onshore communication.which realized ship-shore information sharing.realize the seamless interconnection of ship's lan,internet and ship company lan.We design and develop data acquisition module based on Canbus and add anti-interference designing.it completes data acquisitiong task and decreases system cost.Onshore remote monitoring system of ship equipment is developed by Dreamweaver.and the database of this system is constructed by SQL Server.By the application of JSP, JDBC and EJB 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 heterogeneous network-based Remote Monitoring System of Ship Equipment is a advanced technology, which interlink the monitoring system onboard and the management system onshore. This is also the trend of shore-board integration.
