摘　　要：同步在多通道余度模型的研究和应用中是一项关键性技术,针对此问题中存在的基于多交叉通道模型和同步时间的静态分配策略,提出同步中的动态时间容错方法,设计基于时间容错的动态表决控制算法.理论分析表明,时间容错的动态表决控制算法扩展了任务处理的时间窗口,极大地提高了对瞬时干扰的抵御能力,从而大幅度提高了余度系统的可靠性.Synchronization in the investigation and application of multi-channel redundancy model is a key technique.Aimed at the static allocation strategy based on multi-cross-channel model and synchronization time,a dynamic fault tolerance method in time synchronization was proposed and dynamic voting algorithm was designed based on fault tolerance of time.It was shown by theoretical analysis that the dynamic voting algorithm of time fault-tolerance would extend the time window for task processing and greatly improve the resistibility against the instantaneous interference,so that the reliability of the redundancy system would be greatly improved.
