双 CPU 环境下飞行控制软件的设计

THE DESIGN IN FLIGHT CONTROL SOFTWARE UNDER DUAL CPU CONFIGURATION

本文介绍运载火箭飞行控制软件在双ＣＰＵ冗余硬件配置下的可靠性设计和可靠性指标分配的方法。文中提到的部分技术经过了实验的检验。

This paper introduces the reliability design technology in flight control software under dual CPU configuration,proposes the general structure of software,along with the principle of failure detection and error treatment Morever,the paper introduces the method of reliability calculation and assignment The technology introduced above is verified to be feasible and fault tolerant by experiments
