基于模糊粗糙集的飞机远程故障诊断模型研究

Study on Model Combined with Rough Sets and Fuzzy Sets in Remote Fault Diagnosis of Aircraft

粗糙集和模糊集结合在飞机故障诊断领域有巨大的发展潜力。针对当前飞机故障诊断中所存在的问题,借助C/S模式,将粗糙集和模糊集结合,提出一种新型的飞机远程故障诊断模型,并且开发出远程诊断系统框架。系统的可行性和有效性得到了飞机故障诊断实例的证实。该系统具有客户端响应快、系统效率高、诊断及时的特点,对于当前民用飞机远程故障诊断具有重要应用价值。

Combination with rough sets and fuzzy sets has enormous development potentials in the field of aircraft fault diagnosis. The problems are directed against existing in fault diagnosis for aircraft at present,in virtue of C/S mode of remote technology,and combined with rough sets and fuzzy sets,a new system-model of remote aircraft fault diagnosis had been put forward,and the system-framework of remote diagnosis system had been exploited. The feasibility and effectiveness of system-model are demonstrated by real examples of aircraft fault diagnosis. It has virtues of fast response for clients,and high efficiency,and timely diagnosis of faults. The system-model has important application value for remote fault diagnosis of civil aircraft at present.
