大型电子装备层次诊断应用研究

根据电子装备诊断的特点,探讨了利用层次性理论对电子装备进行故障诊断的必要性和可行性,给出了层次性诊断中层间诊断和层内诊断的概念、原理及实现方法。首次将可列集的概念引用到层次诊断中,并给出了层次诊断中故障模式空间的选取原则,为层次诊断的工程实现和未来进行多信息诊断提供了基本框架。

Research of Hierarchy Diagnosis Used in Large Scale Electronic Equipment

For the electronic equipment fault diagnosis,the necessity and feasibility of hierarchy theory used in electronic equipment fault diagnosis is discussed.The concept,principle and method of hierarchy diagnosis are provided.In this paper,the concept of countable set is introduced to the hierarchy diagnosis,in the more,the rules that select the fault models space in the hierarchy diagnosis is given,which provides a basic frame for the reality of hierarchy diagnosis and multi-information diagnosis.
