| Abstract:The marine engine faults diagnosis database is introduced from the aspects of system structure, data flow, function as well as design and realization of software are introduced. The strategy of constructing huge historical database based on data integration of varied types of engines on board is proposed. By the analysis of the relationship between the historical data changing tendency of characteristic parameter points and fault mode, assistant analysis of the reasons of occurred faults is accomplished. The new database offers fault handling program for emergency faults on board, and lays the foundation of fault self-monitoring and intelligent diagnosis of marine diesel engines. |
