摘要
操作系统的作用随着飞行控制功能的不断增强而逐渐体现出来。本文结合我国运载火箭飞行软件的发展,梳理出可以考虑采用操作系统的前提条件,对使用操作系统的优劣进行了客观分析。针对飞行控制的典型应用,提出了适宜操作系统承担的基本功能。在此基础上,较为详细地介绍了操作系统中故障与设备状态管理功能的实现,并通过共享资源的使用对如何有效发挥操作系统多任务管理的作用进行了示例。
The function of embedded real-time operation system (RTOS) is gradually emerging along with the development of flight control software. This paper discusses prerequisites and advantage/disadvantage about the application of RTOS, and puts forward the basic function suitable for RTOS in flight control. Based on this, the paper introduces in detail the failure & equipment management, and how to make use of sharing resources by effectively exercising the multi-task management function.
