摘　　要：在航空发动机健康管理系统中,针对机载设备具有在线监测和大容量存储发动机工作数据等复杂业务要求,提出了一种多任务管理和存储管理的应用策略,前者采用优先级抢占机制,后者采用二级缓存模式。最后基于VxWorks操作系统和HRFS文件系统实现了该设计策略,从而验证了上述设计方法可行性。In aero engine health management systems,an application strategy about multitasking management and storage management is proposed to meet the complex demands of the airborne equipment,including online monitoring and large capacity storage of engine working data.Multitasking management uses priority preemption and storage management takes the mode of second level cache.This design strategy is realized based on VxWorks operating system and HRFS file system,the feasibility of the above method is verified.
