| 摘 要： | 对于IEEE-1394b互连的可靠性计算问题,从IEEE-1394b的拓扑结构出发,提出了基于任务的系统可靠性分析方法,建立了IEEE-1394b互连系统的可靠性模型,并给出了系统可靠度矩阵的定义.针对IEEE-1394b协议的特性,提出了IEEE-1394b互连系统的互连矩阵定义.对IEEE-1394b互连系统在航电系统的典型应用进行建模分析,给出其任务路径集和单一路径失效概率,得到了任务路径的可靠度.通过分析中继端口单元对任务路径的影响,得到了中继端口单元对于IEEE-1394b互连可靠性影响最大的结论.

| Abstract: | To solve calculable problem of IEEE-1394b network interconnection reliability,based on IEEE-1394b topology,a task based analysis method of system reliability was proposed,a reliability model of IEEE-1394b interconnection system was developed and the system reliability matrix definition was shown.To accord with IEEE-1394b characteristic,the definition of IEEE-1394b interconnection matrix was proposed.Model analysis of IEEE-1394b interconnection system in avionic system was made.Task routes,single route failure probability and task routes reliability were presented.The relay ports influences were analyzed and the conclusion is that relay ports influence IEEE-1394b interconnection system most. |
