PAGE 精品 青岛理工大学毕业设计（论文） 摘 要 随着现代城市的发展，娱乐项目日益增多，游泳池成为人们日常生活必不可少的娱乐选择。游泳池水质的好坏对人们生活的影响越来越显著，因此必须努力提高水质监测及加投药控制系统的性能，保证游泳池水质的清洁。可编程逻辑控制器，简称PLC，是一种工业控制微型计算机。它的编程方便、操作简单，尤其是高通用性等优点，使它在工业生产过程中得到了广泛的应用。其中的一个应用便是游泳池水质监测及加投药系统的控制，主要用到的便是他的逻辑控制功能。本文主要介绍SIEMENS的PLC产品以及其对应的软件，并且用它来进行游泳池水质监测及加投药系统的控制编程。 关键词：SIEMENS PLC， 游泳池，水质监测，加投药 精品 ABSTRACT With the development of modern cities,an increasing number of entertainment projects, swimming pool become an indispensable choice of entertainment of daily life.The quality of swimming pool water performance of the impact on people’s lives becoming more and more obvious ,it must strive to improve the performance of the quality rectifying and reagent adding control system. Programmable Logic Controller，which used to be called PLC for short ,as one kind of industries control microcomputer obtained the wide application in the industrial production process, for its easy programming, easy operation, and so on. One of which is the control of swimming pool water quality rectifying and reagent adding, and the main function of which used is logic control. This article mainly talks about the product of Siemens plc and software, and use this software to control the swimming pool water quality rectifying and reagent adding.
