1、简易自动响铃装置摘要：简易自动响铃装置是生活中常见的报警装置，报警装置在生产和生活中是随处可见的，它虽然并不复杂，但是在日常的生产生活中起着十分重要的作用，比如一些容易发生危险的地方，人多的场合，如果将要发生危险，报警装置可以提前通知人们，达到防患于未然，在小的方面应用也很多，在这就不一一列举，以前报警装置一模拟电路为主，但由可编程器件构成的电路现在明显比模拟电路优点多，可编程序控制器是一种数字运算操作电子系统，专为在工业环境下应用而设计。它采用了可编程序的存储器，用来在其内部存储执行逻辑运算、顺序控制、定时、计数和算术运算等操作的
2、指令，并通过数字的，模拟的输入和输出，控制各种类型的机械或生产过程。所以可编程逻辑器件现在是主流！根据钢铁厂排放废酸水处理的要求，本文提出了钢铁厂废酸水PH值的控制；介绍了欧姆龙公司的CPM2AH型小型可编程控制器，及上位工控机组态王6.5在本控制系统中的应用。关键词：响铃，可编程器件，PLC，PH值，废酸水，组态王--21--AbstractSimpleautomaticringingdeviceisthecommonlifeofthealarmdevice,alarmdeviceisinproductionanddailylif
