神舟飞船交会对接信息流可靠性设计

为成功实现航天器交会对接,航天器内部及航天器间的协同控制是必不可少的,而信息流的可靠性传输是实现其协同控制的前提条件。针对我国交会对接试验,文章提出了一种交会对接信息流的可靠性设计方案,将信息流处理分为信息采集、信息鉴别和信息转发3步,通过采集通道冗余设计、信息校验、多重转发等手段,建立了信息流的可靠传输通道。此方案具...

Reliability Design for Rendezvous and Docking Information Stream of Shenzhou Spaceship

To accomplish rendezvous and docking,inner-spacecraft and inter-spacecraft cooperation control is essential.Reliable information stream is the precondition to realize inner-spacecraft and inter-spacecraft cooperation control.Focused on the rendezvous and docking experiment of our country,a reliability design for rendezvous and docking information stream is presented in this paper.Information stream processing is divided into three steps： information collecting,information identifying and information transmitting.Reliability information stream transmit path is achieved by redundant design of information collection path,information certification and multiple transmitting.This design is real-time and reliable,it has been applied in Shenzhou spaceship and obtained satisfying effects.
