1、采用性能优良的电源,抑制电网引入的干扰

在PLC控制系统中,电源占有极重要的地位。电网干扰串入PLC控制系统主要通过PLC系统的供电电源(如CPU 电源、I/O电源等)、变送器供电电源和与PLC系统具有直接电气连接的仪表供电电源等耦合进入的。现在,对于PLC系统供电的电源,一般都采用隔离性能较好电源,而对于变送器供电的电源和PLC系统有直接电气连接的仪表的供电电源,并没受到足够的重视,虽然采取了一定的隔离措施,但普遍还不够,主要是使用的隔离变压器分布参数大,抑制干扰能力差,经电源耦合而串入共模干扰、差模干扰。所以,对于变送器和共用信号仪表供电应选择分布电容小、抑制带大(如采用多次隔离和屏蔽及漏感技术)的配电器,以减少PLC系统的干扰。

此外,位保证电网馈点不中断,可采用在线式不间断供电电源(UPS)供电,提高供电的安全可靠性。并且UPS还具有较强的干扰隔离性能,是一种PLC控制系统的理想电源。

2、电缆选择的敖设

为了减少动力电缆辐射电磁干扰,尤其是变频装置馈电电缆。笔者在某工程中,采用了铜带铠装屏蔽电力电缆,从而降低了动力线生产的电磁干扰,该工程投产后取得了满意的效果。

不同类型的信号分别由不同电缆传输,信号电缆应按传输信号种类分层敖设,严禁用同一电缆的不同导线同时传送动力电源和信号,避免信号线与动力电缆靠近平行敖设,以减少电磁干扰。

3、 硬件滤波及软件抗如果措施

由于电磁干扰的复杂性,要根本消除迎接干扰影响是不可能的,因此在PLC控制系统的软件设计和组态时,还应在软件方面进行抗干扰处理,进一步提高系统的可靠性。常用的一些措施:数字滤波和工频整形采样,可有效消除周期性干扰;定时校正参考点电位,并采用动态零点,可有效防止电位漂移;采用信息冗余技术,设计相应的软件标志位;采用间接跳转,设置软件陷阱等提高软件结构可靠性。

 

信号在接入计算机前,在信号线与地间并接电容,以减少共模干扰;在信号两极间加装滤波器可减少差模干扰。

对干较低信噪比的模拟量信号.常因现场瞬时干扰而产生较大波动,若仅用瞬时采样植进行控制计算会产生较大误差,为此可采用数字滤波方法。

  现场模拟量信号经A/D转换后变成离散的数字信号,然后将形成的数据按时间序列存入PLC内存。再利用数字滤波程序对其进行处理,滤去噪声部分获得单纯信号, 可对输入信号用m次采样值的平均值来代替当前值,但井不是通常的每采样。次求一次平均值,而是每采样一次就与最近的m-l次历史采样值相加,此方法反应速度快,具有很好的实时性,输入信号经过处理后用干信号显示或回路调节,有效地抑制了噪声干扰。

由干工业环境恶劣,干扰信号较多, I/ O信号传送距离较长,常常会使传送的信号有误。为提高系统运行的可靠性,使PLC在信号出错倩况下能及时发现错误,并能排除错误的影响继续工作,在程序编制中可采用软件容错技术。


    (3)输出刷新阶段。程序执行阶段的运算结果被存入输出映像区,而不送到输出端口上。在输出刷新阶段,PLC将输出映像区中的输出变量送入输出锁存器,然后由锁存器通过输出模块产生本周期的控制输出。如果内部输出继电器的状态为“1”,则输出继电器触点闭合,经过输出端子驱动外部负载。全部输出设备的状态要保持一个扫描周期。
