基于CBR的HUD故障诊断方法研究

Research on CBR-based HUD Fault Diagnosis Method

HUD是歼击机的主显示器,对于飞行员能否顺利完成作战、训练任务具有至关重要的作用,但因其结构复杂、使用频繁等原因导致故障率较高。为提高对HUD故障诊断的效率,分析了基于CBR的故障诊断方法,构建了基于Visual Studio平台的HUD故障案例数据库,开发了基于CBR的HUD故障诊断系统,实践证明可有效提高HUD的保障效率。

HUD is the main display of flighter planes,which plays a vital role in the pilots′success in combat and training.However,due to its complex structure and frequent operation,the failure rate is relatively high.In order to improve the efficiency of HUD fault diagnosis,the fault diagnosis method based on CBR is analyzed,the HUD fault case database based on Visual Studio is constructed,and the HUD fault diagnosis system based on CBR is developed,which can effectively improve the guarantee efficiency of HUD.
