基于信息融合的柴油机故障诊断策略及仿真系统搭建

Based on Information Fusion of Diesel Engine Fault Diagnosis Strategy and Construction of Simulation System

提出了基于信息融合的柴油机故障综合诊断策略,并利用Matlab/Simulink仿真工具搭建了故障诊断仿真系统.在一个仿真系统中就可以解决柴油机故障的检测、预测和决策分析问题,不需要为每一个问题开发一种单独的解决工具.该系统的应用具有独立性,只要提供了不同状态下的数据,即能广泛应用于多元系统的分析及决策.

Comprehensive diagnosis strategy based on information fusion is built up and fault diagnosis simulation system is developed through Matlab/Simulink. A unique solution for diesel engine fault detection, prediction and de-cision analysis is provided in this process, eliminating the need for developing a tool for each separately. The process is application independent. It can be applied to a wide variety of multivariate problems provided that normal opera-tion and abnormal operation data are available.
