计算机控制系统中的硬件抗干扰措施与接口电路的设计

Antil-Interference and Interface of Circuit's Design in the Hardward of Computer Control's System

计算机控制在各行各业应用越来越广泛,在使用过程中经常会受到不同程度的干扰,以至于系统不能正常工作。本文就如何防止干扰以及对不同的采样信号采取什么样的接口电路进行了探讨。

computers were applied widely in various fields more and more. By using it, it often meets different interferences, so that tire system doesn＇t work normaly. This article has a dissicussion about how to protect interference and which interface circuit must be adopted as different sample sign.
