摘　　要：抗干扰技术和可靠性设计是单片机应用系统不可忽视的重要内容,软件抗干扰是硬件抗干扰的一个延伸和补充,运用得法可以显著提高单片机应用系统的可靠性和智能性,并在一定程度上能减轻或者避免意外事故的发生。单片机实时测控软件的自监视法和互监视法法、软件冗余、数据重复输出、看门狗等一系列软件抗干扰技术能很好地起到这种作用。The technology of anti-interference and the design of software reliability were two essential parts in computer measurement and controlling system,and the software anti-interference technology was a supplement and extension of hardware.It could improve the security and intelligence of computer measurement and controlling system,and avoid or reduce the occurrence of contingencies.These effects were achieved by many anti-interference technology such as self-watch,mutual-watch,redundancy,date recovery,watch dog based on measuring-controlling software in microcomputer measurement and controlling system.
