基于故障树的复杂系统故障诊断软件设计研究

Study of fault diagnosis software design for complex system based on fault tree

可靠性和安全性要求较高的复杂系统对故障诊断工作的要求也很高。根据系统在设计、运行阶段工作中建立有大量的故障树模型的特点,本文将故障树分析方法与基于知识的方法相结合,提出了一种基于故障树的复杂系统故障诊断方法,并且开发了原型系统,实现了对车载大气光学参数测量系统的快速、智能诊断。

Complex systems always have high-level reliability and safety requirements,and same does their diagnosis work.As a great deal of fault tree models have been acquired during the design and operation phases,a fault diagnosis method which combines fault tree analysis with knowledge-based technology has been proposed.The prototype of fault diagnosis software has been realized and applied to mobile LIDAR system.
