提出了一种基于故障树模型的诊断方法，并基于该方法实现了一个故障诊断系统。本文仅讨论确定性推理，对可能性推理将另文详述。首先提出了一种基于故障树的层次诊断模型，给出了故障树的故障传播矩阵，并基于该矩阵提出了一种确定性推理方法。其次，提出了一种面向故障树的基于框架和广义规则的混合知识表示方法。最后在ＣＯＭＰＡＱ４８６微机上、ＷＩＮＤＯＷＳ环境下，用ＢＯＲＬＡＮＤＣ＋＋实现了该诊断系统，并通过对一个电路系统试验台的故障诊断验证了系统的有效性。
A fault diagnosis method based on fault tree model is proposed. Based on this method, a fault diagnosis system is implemented. This article deals only with deterministic reasoning, with another possibility being explained in detail. First, a hierarchical diagnosis model based on fault tree is proposed, fault propagation matrix of fault tree is given, and a deterministic reasoning method is proposed based on the matrix. Secondly, a hybrid knowledge representation method based on framework and generalized rules for fault tree is proposed. Finally, the COMPAQ486 microcomputer, WINDOWS environment, the BORLANDC ++ implementation of the diagnostic system, and through a circuit system test bench fault diagnosis verify the effectiveness of the system.
