描述

3HNE00188-1

 第三类是来自接地系统混乱的干扰。接地是提高电子设备电磁兼容性(EMC)的有效手段之一,正确的接地既能抑制电磁干扰的影响,又能抑制设备向外发出干扰;而错误的接地反而会引入严重的干扰信号,使PLC系统无法正常工作。PLC控制系统的地线包括系统地、屏蔽地、交流地和保护地等,接地系统混乱对PLC系统的干扰主要是各个接地点电位分布不均,不同接地点间存在地电位差,引起地环路电流,影响系统正常工作。例如电缆屏蔽层必须一点接地,如果电缆屏蔽层两端A、B都接地,就存在地电位差,有电流流过屏蔽层。当发生异常状态如雷击时,地线电流将更大。
    此外,屏蔽层、接地线和大地可能构成闭合环路,在变化磁场的作用下,屏蔽层内会出现感应电流,通过屏蔽层与芯线之间的耦合,干扰信号回路。若系统地与其它接地处理混乱,所产生的地环流就可能在地线上产生不等电位分布,影响PLC内逻辑电路和模拟电路的正常工作。PLC工作的逻辑电压干扰容限较低,逻辑地电位的分布干扰容易影响PLC的逻辑运算和数据存贮,造成数据混乱、程序跑飞或死机。模拟地电位的分布将导致测量精度下降,引起对信号测控的严重失真和误动作。
    3.来自PLC系统内部的干扰。主要由系统内部元器件及电路间的相互电磁辐射产生,如逻辑电路相互辐射、模拟地与逻辑地的相互影响及元器件间的相互不匹配使用等。这都属于PLC制造厂家对系统内部进行电磁兼容设计的内容,比较复杂,作为应用部门无法改变,可不必过多考虑,但要选择具有较多应用实绩或经过考验的系统。
    抗干扰设计
    为了保证系统在工业电磁环境中免受或减少内外电磁干扰,必须从设计阶段开始便采取三个方面抑制措施:抑制干扰源、切断或衰减电磁干扰的传播途径、提高装置和系统的抗干扰能力。这三点就是抑制电磁干扰的基本原则。
    PLC控制系统的抗干扰是一个系统工程,要求制造单位设计生产出具有较强抗干扰能力的产品,且有赖于使用部门在工程设计、安装施工和运行维护中予以全面考虑,并结合具体情况进行综合设计,才能保证系统的电磁兼容性和运行可靠性。进行具体工程的抗干扰设计时,应主要注意以下两个方面。

选择深圳长欣,选择放心,售后无忧大量现货,当天顺丰发货!
主营:本特利,英维思,伍德沃德,福克斯波罗、西屋、瑞恩、施耐德莫迪康、ABB、AB、西门子、摩托罗拉、GE发那科、安川、博世力士乐,ACSO,力士乐等各大品牌的DCS系统配件,机器人系统配件,大型伺服系统备件。

先介绍几点经验。
1、先通读一遍“系统手册”(不管能不能看懂,先了解个大概,以便学习编程时查找);
2、由位控逻辑入手,逐渐增加定时、计数等条件,把或、与、非关系理顺;
3、进而练习整数运算、实数运算、类型转换;
4、量程转换、PID调节回路的建立及P、I、D参数的理解(最好是有个物理回路验证,比如变频器+电机+测速传感器);
5、循环、顺序、跳转等程序控制(尽量避免跳转,非跳不可时也是跳的越近越好);
6、中断、通讯、位置控制....

本人以ABB工业机器人配件DSQC系列和Motorola MVME系列,GE 卡件 模块 驱动器系列为主攻。各位电工朋友可根据自己的条件选择适合自己的PLC品牌,由于PLC的基本框架大同小异,学会一种至于其它的学习起来也就简单了。
