摘要
针对航天测控系统容灾备份问题,对系统容灾结构和容灾模式进行了探讨,提出了完整的容灾系统运行模式体系,包括软硬件备份模式、人员备份模式、灾备切换模式、返向数据传输模式、前向信息使用模式、承担任务模式,并逐一进行了特点分析和比较。分析结果表明,在关键任务阶段,容灾备份系统宜采用软硬件热备、返向数据广播、灵活切换、人员常驻的模式运行;在一般任务阶段,宜采用软硬件冷备、返向数据转发、固定切换、人员转场等模式运行。这可为我国航天测控系统容灾方案设计和系统建设提供支持。
Following discussions on backup for space TT＆C （Tracking, Telemetry and Command） systems and the structure and modes of disaster tolerance, this paper proposes a complete system of disaster tolerance system opera tion modes covering hardware and software redundancy mode, personnel backup mode, state switching mode, back- ward-information transmission mode, forward-information using mode and mission undertaking mode. The features of the modes are analyzed and compared. The results of analysis show that hot redundancy of hardware and soft- ware, backward data broadcast, flexible switching and continuous staffing mode should be used in critical mission phases while cold redundancy of hardware and software, forwarding of backward data, fixed switching and staff re- deployment mode should be used in general mission phases.
