船舶柴油机的油液铁谱分析是实现故障诊断的重要方法。基于油液铁谱分析的船舶柴油机故障的传统检测方法是采用超声波固-液界面检测算法，导致柴油机故障信号出现环绕波齐次衰减，故障诊断效果不好。提出一种基于模糊伸缩约束控制柴油机油液铁谱分析的故障诊断方法，基于DSP设计船舶柴油机油液铁谱制谱仪和铁谱故障检测硬件系统，采用ADSP-BF537设计油液铁谱分析的电源，选用ADM706SAR芯片设计电路复位。算法设计中，构建油液铁谱分析能量模糊规则方程，设定模糊伸缩约束控制条件补偿油液铁谱分析模型的不确定性，实现对故障的准确定位和检测。实验结果表明，采用该方法进行柴油机故障信号油液铁谱分析和故障诊断，故障亮点定位准确，具有多故障状态监测应答的性能，故障准确发现概率提高显著。

Ship diesel oil and iron spectrum analysis is an important method to realize fault diagnosis. The traditional meth-od of marine diesel engine fault detection method is taken based on spectrum analysis of oil liquid iron by the ultrasonic sol-id-liquid interface detection algorithm, resulting in diesel engine fault signal appeared and the detection effect is not good. A fuzzy extension constraint control diesel oil ferrography fault diagnosis method is proposed. Hardware system of fault de-tection is designed, the power is designed based on ADSP-BF537, and ADM706SAR chip is used to design the reset cir-cuit. In algorithm design, oil ferrography analysis energy equation is constructed with set fuzzy rules, fuzzy extension con-straint control condition is used for compensation oil ferrography analysis model uncertainty, the accurate localization and detection of fault is realized. The experimental results show that, the method has better fault point positioning accuracy, and it has multiple fault condition monitoring response performance, the accurate fault detection probability increases signifi-cantly.
