子网络级故障的交叉逻辑诊断法

研究了网络发生故障的子网络数不大于3的交叉撕裂准则和子网络级故障的逻辑定位方法，在子网络级故障可诊断性拓扑条件的基础上，提出一种快速诊断子网络级故障的新方法，这种诊断方法与目前国内外流行的互校验（MTC）方法比较，具有以下优点：不受子网络外节点（子网络与子网络级间的关联节点）必须可及的限制；故障诊断计算量小，诊断次数少；可及点可以重复使用。

Intersecting Approach of Fault Diagnosis for Sub-Network-Level

Based on the topological conditions for fault diagnosability at sub networks, this paper presents a new fast approach for fault diagnosis at sub network level of analog circuits. The rules of intersecting tearing are studied for the case with number of faulty sub networks being less than three in large circuits, and logical fault locating method is presented. Compared with the unified decomposition approach, an advantage of the present approach is that it breaks through the limitation that all torn terminals must be accessible and raises re applying efficiency of accessible. Another advantage is that it reduces the range and computing time of fault diagnosis of large circuits.
