摘要: 电子设备是各类航空、航天等高新技术装备必不可少的重要组成部分。与机械类设备存在明显退化状态征兆不同,电子设备退化状态无明显的外在表现,尚无有效征兆对其状态进行刻画,对其进行故障预测与健康管理存在一定的困难。针对该问题,梳理了电子设备故障预测与健康管理技术的基本概念和内涵,介绍了电子设备故障预测与健康管理技术的国内外研究现状,分析了当前复杂电子设备故障预测与健康管理技术面临的挑战和对策。在此基础上,结合未来复杂电子设备新特点及该领域最新研究进展,从基于间歇故障特征的健康状态表征、面向故障预测与健康管理的测试性设计和多源特征融合的健康状态评估等方面,提出了电子设备故障预测与健康管理技术发展的新方向。

关键词: 电子设备, 故障预测, 健康管理, 测试性设计, 间歇故障特征

Abstract: Electronic devices are indispensable parts of all kinds of high-tech equipment in the aerospace field. Different from the obvious degradation characteristic of mechanic equipment, there is no obvious external manifestation of the degradation state of electronic equipment. There is no effective sign to characterize the state, and there are certain difficulties in fault prediction and health management of the equipment. To overcome this problem, this paper distinguishes the basic concepts and connotations, introduces the latest research trends home and abroad, and analyzes the current challenges and countermeasures in prognostic and health management of electronic equipment. The new characteristics of future complex electronic equipment and the latest research progress in this field are discussed. Three new development directions for prognostic and health management technology for electronic equipment are proposed, including health state assessment based on intermittent fault characteristics, testability design for prognostic and health management, and health state prediction based on multi-source information.

Key words: electronic equipment, fault prediction, health management, testability design, intermittent fault characteristic
