大规模电路故障诊断的集团法

Group Method for Fault Diagnosis of Large -scale Analogue Circuits

本文提出了一种可以诊断大规模模拟电路的新方法———集团法 ,它能不经过撕裂直接用于大规模电路 ,且能迅速缩小可疑故障集范围。本文详述了其诊断原理及诊断步骤 ,并给出了诊断实例。

A new method for fault diagnosis of analogue circuits by using group algorithm is presented in the paper. It has the characteristic of reducing the scope of the suspicious fault sets sharply, so it can be directly used for large-scale circuits and it is not necessary to tear them to sub-circuits. Diagnosis principles and steps are described. Finally, the reliability of the method is shown by practical examples.
