干扰是微机控制系统设计及调试过程中经常碰到,而且使人十分头痛的问题,不能较好的抑制干扰,最终将使整个系统无法正常工作,从而导致设计的失败。本文将着重从工程应用角度,对干扰的来源及抗干扰的具体措施,尤其是软件抗干扰措施做一总结,分析和介绍,并列出加入这种措施前后的实验对比情况。对其他微机系统也会有一定的参考价值。
Interference is often encountered in the process of computer control system design and debugging, but also a very headache problem, can not better suppress the interference, will eventually make the entire system does not work, resulting in the failure of the design. This article will focus on the application from the engineering point of view, the sources of interference and anti-interference measures, especially software anti-interference measures to make a summary, analysis and introduction, and lists the experimental comparison before and after the addition of this measure. Other computer systems will have some reference value.
