| 摘 要： | 在实验中开发出来的各种控制小系统经常会出现运行不稳定、死机或停不了机即程序跑飞等现象,这是由于恶劣的工业现场环境如大功率感性负载的干扰所至。基于单片机的“看门狗”技术能解决这个问题。本文将通过应用实例,分别介绍用软件和硬件来实现“看门狗”技术。为技术人员在单片机开发过程中出现的干扰现象提供一个有效的解决思路。

| Abstract: | SCMC curriculum is popular in colleges at present.Some kinds of small systems can be debugged successfully in laboratories,but they can not run well in industry field,which results from bad industry field environment,such as the jamming of high-power inductance load.This paper puts forward watch dog technique to solve this problem.Furthermore,this paper presents software and hardware to implement this technique by practical application,and provides a new solution for anti-jamming during the development of SCMC. |
