摘　　要：功能分布式结构下的实时测控计算机应用系统的可靠性保障有其特殊的背景和要求。在综合研究了当前的各种可靠性保障技术的前提下,提出了分布实施、集中控制的可靠性保障方案。对节点部分采用双工热备份或多机冗余技术,通过硬切换保障系统实时性和对过程的保护。实际应用证明该方案简单易行,比较适用于当前航天测控中心的计算机实时应用系统。There are special background and demand for guarantee of reliability in the realtime TT&C computer application system with function distributed architecture. Based on the comprehensive research of current guarantee of reliability technologies, this paper puts forward a guarantee project of reliability with distributed implementation and centralized control. It uses online dual backup or multiserver redundance plan in all nodes, which meets realtime demand and process protected by hardware switching. The actual application proved that the plan is simple to implement and better to apply to the realtime computer application system in the spaceflight TT&C centers. 
