摘要
回顾了状态监测与故障诊断技术的发展历史,归纳和总结了基于系统数学模型、基于系统输入输出信号处理以及基于人工智能等途径的故障诊断方法。从混合智能诊断技术、BIT技术、远程协作诊断技术三个方面,对现代故障诊断技术的发展趋势和有待解决的问题进行了分析与探讨。提出了故障诊断领域目前和将来的研究方向。
This paper has summarized the history and present status of the theory and engineering application for fault diagnostic technique, analyzed the process and essence of fault diagnostic, introduced some diagnostic methods in common use, and especially mentioned some new trends of such modem diagnostic methods as hybrid intelligent diagnosis, BIT and remote co- operative diagnosis. Lastly, we points out some problems that should be emphasized, and predicts some future research directions about modem fault diagnosis.
