摘　　要：软件冗余技术的应用，使嵌入式系统更加可靠。一般的嵌入式系统为了确保系统程序正常运行使用看门狗，看门狗确实能够避免死机现象的发生，但是其存在干扰导致存储被破坏需要充分编写程序这种风险。为此嵌入式系统开始运用软件冗余技术，馋嵌入式系统可靠性得到连一步提高。The application of software redundancy techniques to make embedded systems more reliable.Embedded systems in order to ensure the normal operation of the system program using the watchdog,the watchdog is indeed able to avoid the occurrence of the phenomenon of death,but there is interference to store programming this risk need to be fully To this end,embedded systems using software redundancy techniques to further improve the reliability of embedded systems.

关 键 词：软件冗余技术 嵌入式系统 可靠性
