摘　　要：提出了一种高可靠的动态可重构3+1容错架构,此架构致力于在系统复杂性、成本和可靠性中找到一个最佳平衡点,结合屏蔽容错和重构容错,相互取长补短,通过多数表决隔离故障传播,采用瞬时故障恢复技术,实现动态重构系统成员关系,使得系统在生命过程中最大化的维持3冗余容错,充分利用冗余资源,并进行重构,最大化地实现3冗余容错,提高系统生命周期过程中的可靠性。A highly reliable dynamic reconfigurable 3+1 fault-tolerant architecture is proposed.This architecture is designed to find an optimal balance point in system complexity,cost and reliability.Combine shielding fault tolerance and reconstruction fault tolerance,and learn from each other.Most voting isolation fault propagation,using instantaneous fault recovery technology to achieve dynamic reconfiguration of system membership,so that the system maximizes the maintenance of 3 redundant fault tolerance in the life process,make full use of redundant resources,and reconstruct,maximize the realization 3 Redundant fault tolerance,improve the reliability of the system life cycle.

关 键 词：冗余容错 容错架构 动态重构 故障恢复
