Abstract: 提出一种改进的基于模式的故障诊断方法。将故障定义为可以用正则表达式描述的模式,避免了传统的用"特殊"事件表示故障的局限性。将正则表达式转化成等价的确定性有限自动机,便于构造故障模式空间。故障模式空间包含系统所有的故障信息,可以描述单故障、故障序列、多故障、间歇性故障等多种故障形式。最后给出基于故障模式空间的可诊断性定义和诊断系统。
English Abstract: An improved method of fault diagnosis based on patterns was proposed.Faults are defined as patterns thatare described by regular expressions to avoid the limitation of traditionally defining faults which usesspecialevents.Regular expressions can be equivalently transformed into deterministic finite automaton,so that fault pattern space canbe easily constructed.All the information of faults can be contained in the fault pattern space,which include fault se-quences,multiple faults,and intermittent faults.Finally,the definition of diagnosability based on fault pattern space wasgiven and a diagnostic system was implemented.
