模拟系统多频故障诊断新方法

A New Approach to Analog Multifrequency Fault Diagnosis

提出一种利用“元件连接模型”概念诊断故障的新方法。用该方法可以求解列出的电路系数函数方程找出故障元件。本文还解决了用上述方法不满足可解条件时查找故障元件问题。

In this paper we present a new fault diagnosis approach based on the idea “Components Connection Model”. With this method, we can find out the fault components by calculating the equations of coefficient function of the circuit. It is also presented in this paper that using fault logic function to diagnose the fault compotents is effective if the diagnosis condition is not satisfied.
