模拟电路的子网络级—元件级的故障诊断

SUBNETWORK LEVEL-ELEMENT LEVEL FAULT DIAGNOSIS FOR ANALOGOUS CIRCUIT

本文给出作定期检测的线性模拟大网络的故障诊断的一个新算法。该法将多级撕裂的子网络级故障诊断与元件级k故障诊断相结合,在元件级算法中又首次引进Steiner三连系,采用组合覆盖技术,显著地减少了诊断的测后计算量。

In this paper, a new approach of subnetwork level-element level fault dia- gnosis is proposed for the large-scale analog linear network that is monitored periodically by measurement tests. It combines the subnetwork level fault dia- gnosis under multi-tearing with k-fault element level diagnosis. In the element level algorithm, Steiner system is first imported, and the combinational cover- ing technique is adopted. Therefore, the amount of after-test computation is greatly reduced.
