【摘要】 本文利用故障树的分析方法，对ＢＩＴＢＵＳ总线结构的多机通讯系统和冗错ＢＩＴ－ＢＵＳ总线结构的多机通讯系统进行了可靠性分析，从而得到了它们的可靠度和ＭＴＴＦ。通过比较，可以证明冗错ＢＩＴＢＵＳ总线结构的双机和多机通讯系统要比非冗错的双机和多机ＢＩＴＢＵＳ总线结构的双机通讯系统可靠，因此它在ＬＣＦ型超速防护系统中应用。更多还原

【Abstract】 By using Fault Tree Analysis Method,this paper analyzes the reliability of redundant and nonredundant BITBUSstructural communication network systems of two computers or multipe computers,The network systems’reliability and MTTF(Mean Time ToFirst Failure)are obtained.By comparing the reliability measures of the redundant BITBUSsystems with those of the nonredundant BITBUS systems,it is recognized that the redundantBITBU5systems are more reliable than the nonredundant BITBUS systems.更多还原
