摘要
故障预测与健康管理(Prognostics and Health Management PHM)系统对于推动作战飞机从"事后维修"、"定时维修"向"视情维修"转变具有十分重要的意义。针对新一代作战飞机的技术特点以及在维修保障方面的需求,对机载PHM系统体系结构的3种备选方案进行了对比分析,提出了一种由模块/单元层PHM、子系统级PHM、区域级PHM和平台级PHM等4层集成的层次化体系结构,并着重从层次的划分、组成要素的功能描述、信息传输和外部逻辑等几个方面进行了论述。
The prognostics and health management （PHM） system is now playing an important role in promoting transition of the operational aircraft from run - to - failure, scheduled preventive maintenance to condition - based maintenance. Considering technique characteristics and maintenance demand of the new generation operational aircraft, three different backup blue prints of on - board prognostics and health management system architectures are contrasted, and then a layered architecture is presented, which include vehicle level PHM, area level PHM, subsystem level PHM and module / component PHM. Finally, the division of hierarchy, function description of elements, information transmission and external logic are discussed.
