应用有向图的航天器信息流设计方法

摘要

As multi﹣mission,multi﹣cabin,schedule﹣irreversible complex space missions put for﹣ward higher requirements for information flow design,this article analyzes the problems of tradi﹣tional document﹣based information flow design methods,as well as the rules and characteristics of complex spacecraft information flow design,and based on the layering concept of system engi﹣neering,a design method of hierarchical spacecraft information flow based on directed graph is proposed in this paper.This method converts the traditional unstructured document design mode into a digital model description design method, and establishes a typical digital model of telemetry remote control information flow,which is verified in engineering practice.This method is of versatility,scalability and re﹣usability,enabling digitization and visualization of information flow design.It can provide reference for complex spacecraft information flow design and inde﹣pendent health diagnosis.%针对多任务、多舱段、任务时序不可逆的复杂航天任务信息流设计需求,文章分析了传统基于文档驱动的信息流设计方法存在的问题以及复杂航天器信息流设计规律和特点,并结合系统工程的设计理念,提出了一种应用有向图的分层航天器信息流设计方法.将传统的非结构化文档设计模式转换为用数字化模型描述的设计方法,建立了典型的遥控遥测信息流的数学模型,并在航天器信息流设计的工程实践中进行了应用验证.该方法具有一定的通用性、可扩展性和可复用性,实现了信息流设计过程的数字化和可视化,可为后续复杂航天器信息流设计和自主健康诊断等提供参考.
