| Abstract:Based on the analysis of historical operation data and system structure of a ship's diesel engine, the design and development of diesel engine's fault diagnosis software was carried out with the use of expert system. The data base constitution and data mining technology are introduced in detail, and the key technologies to realize fault diagnosis, such as fault classification, Bayesian network reasoning and diagnostic model, diesel engine fault diagnosis and prediction based on SVM, as well as expert system are analyzed. Moreover, the software implementation of this fault diagnosis system is described. |
