摘要
介绍了高速动车组故障诊断系统总体架构。应用专家知识建立高速动车组典型事件故障树,确定顶事件、中间事件和底事件。根据故障树结构关系设计了以推理机为核心的故障诊断专家系统,并通过在列车中央控制单元中编程预先设置推理规则,实现了高速动车组的故障诊断专家系统构建。
The typical architecture of fault diagnosis system for high-speed EMU is introduced. The knowledge of experts in this field is used to establish a fault tree for top event,intermediate event and bottom event determination. Then,based on the structure of fault tree,a fault diagnosis expert system with inference engine as the core is designed, the rule of inference is set in advance by programming in the central control unit of the train. In this way,the design proposal of fault diagnosis expert system is achieved.
