摘要:

根据大型号液体推进剂导弹及运载火箭动力设备系统的特点和一般专家系统所存在的主要问题，提出了一种基于多进程、多层次概念的实时故障诊断系统结构模型，探讨了使用该结构模型处理异步事件、增进系统容错能力、实现出现故障时的集中注意力、对系统状态进行自学习等问题的基本思想，以此开发的某型号导弹动力设备实时故障诊断系统已成功地应用于部队。

Abstract:

According to the features of the power equipments for large liquid propellant missile and rocket as well as the main problems of expert systems,this paper puts forward a real time fault diagnosis system model which is based on multi process and multi layer concept,studies the basic ideas of dealing with asynchronous event,of enhancing fault tolerance capacity of system,of focusing the atention when the fault comes,of self studying from system state.Based on these,the real time fault diagnosis systems for a missile power equipments has successfully used in troops.
