一种双余度非相似容错计算机软件设计

摘要

As an important design method of fault-tolerant technology,dissimilar redundancy design is widely applied in many fields,and mainly applied in flight control system in aviation field.An existing and suitable real-time operating system in dissimilar dual-computer was analyzed,based which the operating framework and task scheduling algorithm suitable for airborne flight control system was realized.The key technology of dual-computer redundancy management was discussed based on the framework.Results show that the framework and algorithm meet the requirements of flight control system.%非相似余度设计是容错技术的重要设计方法,在很多领域都有广泛应用,在航空领域主要应用于飞行控制系统.在非相似双机架构下分析现有且适宜的操作系统,并在此基础上构建适合机载飞控系统的底层运行框架和任务调度算法,在此框架下研究双机余度管理的关键技术.研究结果表明,所设计的软件框架与算法满足飞控系统要求.
