LONWORKS Fieldbus Is Applied In The Monitor And Control System Of Marine

Practically, the reliability, maintainability, real-time control ability and interoperability are required by the monitor and control system for marine engine room. However the monitor system based on the multi-microprocessors and the hierarchical structure is not so satisfied in such requirements, owing to its complex structure and devoted communication sub-stations, in order to solve mis problem, a design method of intelligent monitor system based on field-bus control system (FCS) for marine engine room is presented in mis dissertation.The Lon Works technology, one of the many fieldbus technologies developed in recent years and available as an open standard to all manufacturers, now has been widely used in the automatic areas ranged from industry, building, transportation, to power system. It integrates computer, network and control into one technology and displaces proprietary centralized systems with open, highly distributed, interoperable systems. Neuron chip, whose network protocol has all 7 layers of the ISO/OSI reference model, has the abilities of both communication and application control, and provides 34 I/O object The technology also provides versatile methods for building and managing the control networks.In this paper, one solution for the control network are demonstrated based on the LonWorks technology. The main principles for the definition of the different nodes in a network are given, and the characteristic of the real-time control is thoroughly analyzed. Furthermore, great emphasis has been put to discuss node design and network design.
