基于二叉树的某型船柴油机控制系统故障诊断专家系统

Fault Diagnosis Expert System for Diesel Control System on a Certain Ship Based on Binary Fault Tree

  • 摘要: 专家系统可以解决复杂系统的故障诊断,其中知识库和推理机是其核心内容。首先利用故障树表达某型舰柴油机控制系统各故障事件之间的逻辑关系,然后将故障树转化为二叉故障树,与专家系统相结合,完成专家系统知识库和推理机的设计。将该方法应用于某型船柴油机控制系统的故障诊断,结果表明,专家系统的知识库存储结构简单、易于维护,推理机的逻辑推理关系简单,易于实现。

     

    Abstract: Expert system has successfully resolved fault diagnosis of complicated system. Its core is knowledge base and inference machine. In this paper, fault tree was used to express the logical relations of faults in the di esel control systems on a certain ship. Then, it was translated into binary fault tree, which could design the knowledge base and inference machine of expert system, after being combined with the expert system. This me thod was used to diagnose the fault of diesel control system on a certain ship. The results show that the storage structure of expert system is simple and easy to maintain, and the logical inference process of inferenc e machine is concise and easy to carry out.
