摘要:

针对飞机机电综合管理平台应用任务多、实时性强、安全性高的特点,通过研究ARINC653标准中的分区、进程两级任务调度机制和机载机电系统应用软件特点,设计了飞机机电综合管理平台应用任务分区划分、分区时间调度规划和分区内任务调度的具体方法；该方法可实现不同安全级别应用任务安全、实时共享机电综合管理平台资源；仿真实验结果表明,该方法能确定性保证飞机机电综合管理平台全部任务的可调度性,提高了系统安全性和硬件资源利用率,降低了系统开销。

Abstract:

In view of the aircraft electro-mechanical integrated management platform application tasks, real-time, high security features, by researching ARINC653 standard and the characteristics of the application tasks of the electro-mechanical integrated management platform, proposes application tasks partition dividing method、partition scheduling strategy and tasks scheduling algorithm within partition. The method can achieve that different security levels of real-time application tasks can be implemented to share the same processor resources. The simulation results show that the method can guarantee the performance of all the tasks of the electro-mechanical integrated management platform of aircraft, and also improve the system security and hardware resource utilization, and reduce the system overhead.
