在载人航天任务中,为确保在运载火箭待发段出现危及航天员生命安全的紧急情况时能可靠、迅速地实现航天员的逃逸救生,一般采用待发段地面逃逸指挥控制系统承担待发段地面逃逸辅助决策、地面逃逸指令生成和发送的任务。提出一种基于双冗余架构的高可靠待发段逃逸指挥控制系统设计方案,集成了冗余供配电控制、冗余网络通信和安全控制以及远程测控等功能,系统设计均突出高可靠性、安全性、人机工学设计及国产化设计,可满足载人航天待发段逃逸救生的需求。
In the manned space mission, in order to ensure reliable and prompt escape and rescue of astronauts in emergency situations where the launch vehicle is in danger of endangering the lives of astronauts, the command and control system of the surface flight escape zone Segment Escape Assist, Ground Escape Command Generation and Sending. This paper presents a design scheme of high reliable command system for headway and runaway based on dual redundancy architecture. It integrates functions such as redundant power supply and distribution control, redundant network communication and security control, and remote monitoring and control. The system design emphasizes high reliability , Safety, ergonomic design and localization design to meet the needs of manned space flight to escape the life-saving section.
