基于油液监测的柴油机磨损故障诊断系统

运用专家系统的原理和构建万法，建立了知识库模型，编写了搜索推理代码，并在此基础上基于C#和SqlServer采用油液分析技术中的光谱分析、铁谱分析和常规理化分析，建立了柴油机磨损故障诊断系统．该系统可用于诊断磨损的部位、类型和性质．以济南柴油机厂的4190柴油机为研究对象，对该系统进行了检验，实验结果表明该系统能够定位柴油机磨损故障的部位，并诊断其故障性质及原因．

Diesel Engine Wear Fault Diagnosis System Based on the Oil Monitoring Technology

Three common oil analysis techniques, namely Spectrometric analysis, Ferrography analysis, and oil chemical- physics analysis, and in this paper, the expert system theory and method for building it have been introduced together; on base of establishing the knowledge model and writing the search reasoning code, a wear fault diagnosis system by using of C# and SqlServer used to diagnose the wear failure reason and nature has been completed. With experts＇ knowledge in the field of oil monitoring, established the rule knowl- edge and its weights; use the Jinan Diesel Engine Factory 4190 diesel as the object of study, verified this sys- tem can locate the mechanical failure parts and the reason, nature of the Diesel engine wear failure.
