摘要
故障诊断的第一步是选择节点,这对未知电路来说就更复杂。文章提出了一种基于功率谱熵的主要针对未知电路的节点分类方法,再结合节点的电特性就可以将所有的节点进行分类。最后,文中给出了具体的节点分类规则和分类流程,其具有较强的理论依据,可靠性高。
Being the first step to fault diagnosis,node classification is more complicated for unknown circuit.A node classification method based on power spectral entropy mainly towards unknown circuits is presented in this paper,and then the electric properties of the nodes to complete further classification is used.Finally a specific node classification rule and process are proposed in this paper with a strong theoretical basis and high reliability.
