摘　　要：为进一步提高船舶柴油机故障诊断的可靠性,将一种基于模糊信息多级融合的故障诊断方法应用到船舶柴油机的故障诊断中.该方法将各级诊断数据充分融合后再进行船舶柴油机的故障诊断,应用结果表明该方法准确有效,不但在正常情况下作出了准确的故障诊断,而且在局部检测传感器失灵发生误检的情况下亦能避免船舶柴油机故障诊断的误判,为提高船舶柴油机故障诊断的可靠性提供了有益的借鉴.To enhance the reliability of fault diagnosis in marine diesel engine, a fault diagnosis method based on fuzzy information multilevel fusion is applied to the fault diagnosis of marine diesel engine. This method processes fault diagnosis of marine diesel engine after fusing diagnostic data in each level once more, application results indicate that the method is accurate and available, which not only can make correct diagnoses in the general case, but also can avoid the false judgment of fault diagnosis of marine diesel engine in the case of failures of the local detection sensor, and give a beneficial reference to enhance the reliability of fault diagnosis in marine diesel engine.
