【摘要】 讨论了开展复杂电子装备潜隐性故障诊断的重要意义,对复杂电子装备潜在故障诊断技术的发展趋势进行了分析,针对电子装备潜隐性故障特征信息少、诊断难的问题,提出了考虑电子装备多态可靠性分析进行潜隐性故障诊断的若干关键技术问题,并给出了相应的解决思路;首先通过开展电子装备多状态的关联性和继承性研究,实现装备潜在故障可靠性状态的科学评定;然后采取动态融合零失效检测数据和故障信息的方法获取潜隐性故障的小样本特征参量集,并将其嵌入潜在故障模式识别模型,从而识别具有明显非线性和不确定性特征的潜隐性故障,为实现复杂电子装备潜隐性故障的早期预测提供了新的技术途径,在装备的生产和使用中有着具有良好的工程应用前景。更多还原

【Abstract】 Based on analysis of electronic equipment fault diagnosis technology,important signification of electronic equipment potential fault diagnosis is discussed.The progressing trend of electronic equipment fault forecasting technology is analyzed.Then,key-technology of potential fault diagnosis on complex electronic equipment is introduced,and corresponding resolvent is put forward.Reliability states of electronic equipment with potential fault are scientific judged by researching successive character and relationship of electronic equipment multi-states,little sample lots potential fault characteristics are obtained by dynamic fusing test data and fault information,then potential fault is identified.These establish foundations of theory and technology for potential fault forecasting,quality evaluating,and maintaining of electronic equipment.更多还原
