2、干扰***
以上列举了产生干扰的几种原因,这些干扰如果得不到很好的***和防止,轻则影响系统的测量技术精度,因而使正常的控制无法实现,重则会造成设备损坏,人们在长期的工程实践中总结出了很多干扰***的方法。
(l)隔离
①使所有的信号线很好地绝缘,使其不可能漏电,这样,防止由于接触引入的干扰;
②将不同种类的信号线隔离铺设(在不同一电缆槽中,或用隔板隔开),我们可以根据信号不同类型将其按抗噪声干扰的能力分成几等。
模拟量信号(模人、摸出,特别是低电平的模人信号如热电偶信号,热电阻信号等)对高频的脉冲信号的抗干扰能力是很差的。建议用屏蔽双绞线连接,且这些信号线必须单独占用电线管或电缆槽,不可与其它信号在同一电缆管(或槽)中走线。
低电平的开关信号(一些状态干结点信号),数据通信线路(RS232、***485等),对低频的脉冲信号的抗干扰能力比上种信号要强,但建议***好采用屏蔽双绞线(至少用双绞线)连接。此类信号也要单独走线,不可和动力线和大负载信号线在一起平行走线。
