摘　　要：CPCI总线结构标准自发布至今已广泛应用于航天测控领域,而热切换技术的进一步研究,可有效减少测控系统平均维修时间,提高系统任务可靠性。以CPCI总线结构为基础,通过讨论与研究给出一套完整的改进设计方案,以改进电源管理控制底层设计为途径,使测控系统具备高可用等级热切换功能,从而满足增强系统可靠性与维修性的迫切需求。The bus architecture of compact peripheral component interconnect（ CPCI） has been gaining immense popularity in the area if aerospace test since its establishment by PCI industrial computer manufacturer＇s group（ PICMG）. High availability（ HA） system allows measurement and control system to reduce the mean-time-to-repair（ MTTR） effectively and improve the mean time between critical failures（ MTBCF）. CPCI bus structure is taken as an example to demonstrate a perfectly developed design schemes through discussion and research. With the way to improve the power management,the underlying design can support the HA level hot swap and hot backup function,which is possible for the measurement and control system to meet the urgent need for enhancing reliability and maintainability of the system.
