摘要
针对传统故障诊断方法的缺陷,将基于案例的推理技术引入到故障诊断系统中,介绍了基于案例推理的故障诊断方法的机理,阐述了案例的表示、检索和案例库的建立,实例诊断表明,该方法相比传统的故障诊断方法来说具有简单、诊断精度高的优点,是有效可行的。
Case-based reasoning is applied to fault diagnosis system. The mechanism of the CBR-based fault diagnosis method is intro duced. The expression and search mechanism of case and the establishment of a database of case are illustrated in detail. The example results showed that this method can turn out higher-quality results compared with traditional, and the diagnosis results are reliable.
