基于故障树的导航装备故障诊断专家系统研究

Research on the fault diagnosis expert system of the navigation equipment

针对导航装备比较常见的故障诊断方法，提出了基于故障树的通用故障诊断的概念．为使故障诊断专家系统具有通用性，在分析故障树流程图特点的基础上，提出了逻辑关系的数字编码和故障诊断数据库的思想，设计了对导航装备故障诊断专家系统具有通用性的系统软件及数据库．

According to the more common methods of the fault diagnosis of the navigation equipment, a concept of the general fault diagnosis based on the fault tree is presented. On the basis of analyzing some characteristics of the flow chart of fault tree, an idea of numerical code of logical relation and date base of fault diagnosis is put forward to make expert system generalized. The system software and date base are designed.
