基于信息融合技术的核动力装置智能故障诊断系统研究

Study on Intelligent Fault Diagnosis System of Nuclear Power Plants Based on Information Fusion Technique

将信息融合技术应用到船用核动力装置故障诊断中,建立由故障树专家系统、神经网络诊断系统和机理模型验证系统构成的空间融合架构,充分利用系统深层知识、浅层知识和机理模型知识,经仿真验证,信息融合诊断系统可有效提高故障诊断的可靠性。

The technology of information fusion is used in the fault diagnosis for ship nuclear power plants in this paper.The space fusion structure is built based on fault tree expert system,NN diagnosis system,and mechanism model validation system.Not only the system deep-level knowledge,but also the shallow knowledge and the mechanism model knowledge are fully used.The simulation validation and verification showed that the information fusion diagnosis system could improve the fault diagnosis reliability effectively.
