基于飞参数据的飞机故障诊断专家系统研究

Research on the expert system of aircraft fault diagnosis based on flight parameter data

传统人工诊断的方式对飞参数据进行分析,工作量大,效率低。结合专家系统思想,通过对专家知识库和推理机的设计,将所收集的专家资料和数据以产生式表示法的形式存储于计算机中,实现了对飞参数据的快速高效故障诊断,大大提高了飞机排故和放飞的效率,保证了飞行安全。以国产某型飞机为例,验证了该专家系统的优势和性能。

The traditional manual diagnosis method for analyzing flight data is not only a heavy workload,but also has a low efficiency.Therefore,combined with the idea of the expert system,through the design of expert knowledge base and inference engine,the collected expert data are stored in the computer in the form of production expression,so as to realize the rapid and efficient fault diagnosis of flight data,greatly improve the efficiency of aircraft troubleshooting and flight,and ensure the flight safety of the aircraft.Finally,taking a domestic aircraft as an example,this paper verifies the advantages and performance of the expert system.
