| 摘 要： | 对于光纤分布式数据接口(FDDI)互连的航空电子系统可靠性问题,从FDDI互连系统的基本拓扑结构出发,提出了基于任务的系统可靠性分析方法,建立了FDDI互连系统的可靠性模型;根据系统可靠度矩阵,给出了FDDI互连系统平均可靠度计算公式。针对系统故障时可靠性问题,依据系统可靠度矩阵和系统平均可靠度计算公式,推导出FDDI互连系统不同单一故障状态时的系统平均可靠度计算公式。最后通过应用分析,对不同状态时系统平均可靠度计算公式进行了验证,验证了模型和算法的有效性和正确性,为航空电子系统的可靠性计算提供依据。

| Abstract: | The reliability of Fiber Distributed Data Interface (FDDI) interconnection in avionic system was studied. Based on the basic FDDI interconnection topology,a task based reliability analysis method was proposed,and a reliability model was established for the FDDI interconnection system.The formulas of the system average reliability were used to describe reliability model according to the system reliability matrix.Considering the situation when fault appearing,an average system reliability formulas was given for different situation of single fault,which was based on the system reliability matrix and average system reliability formula.In the end,the average system reliability formulas about different states were analyzed by using an illustration,which proved the effectiveness of the model and the algorithm. |
