【摘要】 机载计算机的任务可靠性对飞机飞行安全至关重要,而提高任务可靠性的一个有效途径就是进行余度设计。文章从研究两种常用的双余度容错模型出发,将桥联模型应用于机载计算机的双余度设计。通过对工作模型的故障容错机制的分析,证明该双余度设计可有效提高机载计算机的任务可靠性,具备一定的工程实用价值。更多还原

【Abstract】 The mission reliability of utility management computer is critical and essential to aircraft flight safety,and an effective way to improve the mission reliability is to carry out dual redundancy design.Starting from the study of two commonly used reliability models,this paper uses the bridging model in dual-redundant design of utility management computer.The fault-tolerant mechanism analysis of bridging model proves that the dual-redundant design can effectively improve the mission reliability of utility management computer,and has a certain practical value.更多还原
