Study Of The Monitoring System Of Ship Power Plant Based On LabVIEW

The close combination of virtual instrument technology and the computer science gradually finds itself in the automation area of the ships power station. Using the computer development architecture instead of traditional single metering instrument, and on the hardware platform in which computer is the core, users design instruments and meters and define their functions, which satisfies the need of real time monitoring system and not only realizes all the functions of ordinary instrument but some that cannot be achieved by common instruments as well.According to the requirement of ship design and teaching experiments, a real time monitoring system of ship power station was designed based on LabVIEW. This system applied both industrial control computer and single chip as two control parts, and realized the real time communication between them by Modbus protocol while achieving the field monitoring of the diesel engines of the ship power station. A specific practicing structure of the monitoring system was presented, and the key points of the monitoring program were also discussed in detail.The monitoring system of ship power station based on LabVIEW has been tested in the laboratory of ship power station, and it successfully realized the field monitoring of the two diesel generating set. The stable system has advantages of a friendly interface between users and the computer, complete functions and great visual effect. The method combing industrial control computer and single chip based on LabVIEW gives an effective way in the developing of intellectual graphic monitoring instrument, and it has practical values in the design of intellectual control of the modern ship power stations. The design of this system offers experiment platform for undergraduates of specialty in ship and ocean science, and it has general and practical values in the design of other similar application system.
