Development And Research Of The Ship Diesel Engine Monitoring System

As the main power equipment or the heart of the ship, diesel engines'reliable running is the key to guarantee the security of the marine. The monitoring of the ships diesel engine's running status can discover promptly the breakdown hidden danger, avoid the burst breakdown causing the engine off and safety incident's occurrences, thus has the vital significance. This dissertation takes the 16VPA6 diesel engine as the object of study, uses virtual instrument technology and so on to develop the ships diesel engine monitoring system, and has carried out the thorough research on the related technology.This article has first analyzed the ships diesel engine monitoring system's research present situation and the trend of development, and has carried on the detailed introduction to monitoring system's new technical like embedded technology and the virtual instrument technology. In the full understanding present situation and in the new technology's foundation, has further been clear about the technique route and primary task of the dissertation.In the above foundation, this article has carried on the system design to the ships diesel engine monitoring system. Under the premise of satisfying the system design request, consummates the design ideas,works out the design proposal, and anticipates the development results, indicates the direction for the later word hardware design and the software design.Then, this article has carried on the detailed hardware design and the software design to the monitoring system. And, the hardware design mainly includes the signal modulator band the data conversion box's design, and the hardware which needs to the system in has carried on the introduction. The software design part firstly expound sthe software frame and select the software development platform, then designs separtedly in detail according to function modules setted in software frame, and introduces the matainence and extendability of the software program.Finally, the dissertation has carried on the experimental verification and the analysis of the developed diesel engine monitoring system. The result indicates that this ships diesel engine monitoring system operational aspect is good, satisfies the requested function in substance. The monitoring system can complete the diesel engine signal monitoring well, and can withdraw the unusual signal to provide the data for the following diesel engine failure diagnosis expert system.
