基于知识的航电设备故障诊断专家系统

Fault Diagnosis Expert System for Aerial Electronic Instruments Based on Knowledge

为了解决航电设备故障难以诊断的问题,设计一个基于知识的航电设备故障诊断专家系统。该系统中的知识表示形式及与之相配合的基于确定性理论模型的不确定性推理方法,以及基于示例的推理方法可以实现航电设备的故障推理和诊断,其规则的可信度可达到理想的程度。

In order to solve the problem of aerial electronic instruments which is complicated,a fault diagnosis expert system for aerial electronic instruments is designed based on knowledge.It can implement fault reasoning and diagnosis by knowledge expressing mode,uncertainty reasoning method based on certainty theory model which supports the mode,and reasoning method based on demonstration,and the reliability of the rule can achieve an ideal degree.
