摘　　要：针对MCS-51单片机系统常用软件抗干扰技术进行研究,探讨软件陷阱捕获技术、软件看门狗技术、开机自检技术及指令冗余技术等常用软件抗干扰技术的具体实现。这些技术在单片机系统中的应用,大大节省了硬件资源,最大限度地降低干扰对系统工作的影响,提高了系统的可靠性。In this paper,according to MCS- 51 single chip microcomputer system, we have researched its software about anti- interference technique, and have discussed its realization of anti- interference technique, such as software trap, software watchdog,startup auto- check, and instruction redundancy. Usage of these techniques in the single chip microcomputer system, we can save hardware resource greatly,and reduce interfere on system＇s work, and improve system＇s reliability.
