湖南工业大学本科毕业设计(论文)I摘要在游人和居民经常光顾的场所,如公园、广场、旅游景点及一些知名建筑前,经常会修建一些喷泉供人们休闲、观赏。这些喷泉按一定的规律改变喷水式样,如果再与五颜六色的灯光相配合,在和谐优雅的音乐中,更使人心旷神怡,流连忘返。随着可编程控制器在我国的迅速发展,对花式喷泉的控制要求也越来越高,使得越来越多的控制部分需要可编程控制器来实现。使用PLC控制花式喷泉,具有使用方便,运行可靠,控制程序设计简单等优点。用梯形图方法编程,可以使设计思路清晰,编程简便.若需要改变喷水花样和喷水时间,设计方案不必作很大调整,只要把控制程序作相应的修改,即可实现控制目的。本设计讲述的是如何利用PLC控制喷泉喷水方式,产生各样的样式,并给出了花式喷泉的喷水花样,选择西门子的PLC作为控制器,分配了4种喷水花样下PLC的I/O接口、设计了PLC的外部接线图及控制梯形图,同时用MCGS组态软件完成了花式喷泉系统人机界面的设计,通过人机屏面和西门子PLC之间的通讯,实现了小型喷泉系统基于PLC监控。关键词:PLC,喷泉,控制系统,组态湖南工业大学本科毕业设计(论文)IIABSTRACTTheplacewhichpatronizesfrequentlyinthetouristandthereresident,beforelikethepark,thesquare,thescenicsiteandsomewell-knownconstructions,willconstructsomeeruptivefountainstosupplythepeopleleisure,watchingfrequently.Theseeruptivefountainsaccordingtocertainrulechangesprayingofwatermodel,ifcoordinatesagainwiththecolorfullight,inwiththeharmoniousgracefulmusic,causesthehumantobecompletelyrelaxed,forgetstoreturn.Astherapiddevelopmentoftheprogrammablelogiccontroller,ithasbeenappiedinthecontrolfieldtomeetthemoreandmoredemanding.Withtheadvantagessuchasitshighreliabilityandeasyofuse,itcansimplifythedesignlogicandprogramming.Whencontrolmentdemandchanging,theuserjustneedtoadapttheprogram,avoidingmodifythedesignplanifneedstochangethepatternandtimeoffountains.WhatthisarticlenarratedishowusingthePLCcontroleruptivefountainsprayingofwaterway,hasallkindsstyles.Forepatternsofthefountainweregiven.ThedistributionofPLCisinput/outputinterfacewasdescribedunderthosepatterns.Theexternalhookupandladderdiagramsweredesignedalsointhispaper.Theconfigurationrealizationofthesystemwasintroduced.ConfigurationdynamicsimulationwascompletedbycommunicatingtheconfigurationsoftwareandthePLChardwareofSIEMENS.Keywords:PLC,eruptivefountain,controlsystem,Configuration湖南工业大学本科毕业设计(论文)III目录摘要.......................................................................IABSTRACT...................................................................II第1章绪论................................................................51.1课题研究背景.............................................................51.2课题设计目的和意义.......................................................51.3课题设计内容.............................................................6第2章系统控制方案的确定...............................................82.1花式喷泉的概述...........................................................82.2系统设计基本步骤.........................................................92.3系统控制方案............................................................102.4花式喷泉控制系统的原理图................................................122.4.1多花样喷泉设计原理..................................................122.4.2多花样喷泉设计原理图................................................13第3章系统硬件设计.....................................................143.1可编程控制器(PLC)的选择...............................................143.1.1PLC概述............................................................143.1.2PLC的选型..........................................................143.2开关量输入模块的选择....................................................163.2.1开关量输入模块的选择................................................163.2.2开关量输出模块的选择................................................163.3水泵的选型..............................................................173.4喷头的选择..............................................................183.4.1喷头的介绍..........................................................183.4.2各种喷头的选择......................................................193.5电磁阀的选型............................................................213.6彩灯选型................................................................22第4章系统软件设计.....................................................24湖南工业大学本科毕业设计(论文)IV4.1I/O分配表..............................................................244.2I/O接线图..............................................................244.3花式喷泉控制系统流程图..................................................254.3.1花式喷泉控制系统操作说明............................................254.3.2花式喷泉控制系统的外部接线图........................................264.4梯形图设计..............................................................264.5组态监控设计............................................................264.5.1MCGS工控组态软件的简介.............................................264.5.2制作工程画面........................................................274.5.3变量的定义..........................................................294.5.4变量的连接..........................................................314.5.5程序运行组态监控....................................................33结论......................................................................37参考文献...................................................................38致谢......................................................................39附录......................................................................40湖南工业大学本科毕业设计(论文)5第1章绪论1.1课题研究背景随着城市化进程的加速,花式喷泉可以在人们周围随处可见。比如广场,大厦,小区等。花式喷泉是人造小气候,在炎热的夏日可以起到增湿和降温的作用;也为水体充氧,有利于水体增加自净能力,起到防止水体黑臭的作用。人们经常看到喷泉按一定的规律喷水,景色迷人;花式喷泉运行的灵活性是评价花式喷泉优劣的关键,而这与花式喷泉的控制系统息息相关。花式喷泉可以根据自己的设计,设计出各种各样的花样,加上灯光,能给人有种不错的视觉享受。传统的喷泉控制采用单片机控制
