| Abstract: | 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. |
