摘要
讨论了各种双机冗余备份方案的特点,介绍了一种高可靠性双机热备份的嵌入式计算机设计方案,提高了整个嵌入式系统的可靠性。分析了该方案的工作原理,该方案的故障等级与处理流程,并进一步讨论了数据同步的方法。应用表明本方案切实可行,为运行在其他复杂环境下的实时性嵌入式计算机系统提供了良好的借鉴。
This paper discusses the various features of standby embedded computer system,and introduces a high-reliable hot-standby embedded computer system.This paper analysizes the theory of the fault level and work-flow of the system,together with the method that how to synchronize the data.The application indicates that the system works well,which giving an example for how to improve the reliability of the real-time embedded computer system working in the terrible environment.
