摘　　要：分析了基于知识的故障诊断,针对现有系统不能主动将知识在适当的时候传递给决策者的缺点,提出了一种基于知识管理的、以数据流驱动的、知识主动推送的故障诊断系统的体系结构,分析了其主要层次结构及知识的组织和管理,提出了以数据流驱动的知识主动推送方式.建立了知识主动推送的控制模型,开发了知识管理和数据流驱动的集成原型系统,并以液体火箭发动机试车台的故障诊断为例,实现了基于知识推送的故障诊断系统,后续实验证明了该方法的有效性.Fault diagnosis system based on knowledge has been analyzed. To deal with the disadvantages that the fault diagnosis system can not transfer initiatively the knowledge to the decision-maker at opportune moment, a dataflowriven architecture framework of fault diagnosis system based on knowledge management and knowledge pushing was proposed. Its primary hierarchy, organized and managed mode of knowledge was analyzed, and the dataflow-driven active pushing manner for knowledge was studied. The control mode of knowledge active pushing was founded, and the dataflow-driven integration prototype system based on knowledge management was developed. Finally, taking the fault diagnosis of liquid rocket engine test stand, for example, the fault diagnosis system based on knowledge pushing was conducted, and the latter experiment has shown the effectiveness of the method.
