摘　　要：现代民航客机越来越多地采用电传操纵系统,其维护方法和故障诊断知识的缺乏成为航空公司机务系统的一大难题。为满足飞行操纵系统的维护需要,提出一种智能故障诊断方法,以B777飞机为例,将其飞行操纵系统的FMECA分析作为本体建模的知识源,通过JESS规则推理机,维护人员可迅速进行故障定位,并选择相应的处理措施。这种诊断方法实现了知识在飞机制造商与飞机使用者之间的共享,可为飞行操纵系统故障诊断提供良好的支持。The fly-by-wire flight control system is increasingly used in modem airliners. The Jack of maintenance method and fault diagnosis knowledge becomes a major problem. In order to meet the needs for flight control system maintenance, an intelligent fault diagnosis method is proposed. The FMECA analysis of flight control system of B777 aircraft is taken as the knowledge source of this ontology modeling. By JESS rule reasoning machine, main tenance personnel can rapidly locate the source of the fault, and can select corresponding measures. This diagnosing method realizes the knowledge sharing between aircraft manufacturers and aircraft users, which can pro- vide a strong support for fault diagnosis of flight control system.
