音乐喷泉的PLC设计—毕业论文

青岛理工大学毕业设计（论文）I摘要一些园林建筑、大型公共建筑以及旅游建筑设计中，设计者经常将喷泉以一种艺术形式融合在建筑物中，给人以自然之美与艺术感。当音乐播放时（包括音乐的曲调和音乐的声音大小），喷头有规律的喷水，彩灯有规律的亮灭（达到白天时灯不亮，夜晚时灯有规律的亮与灭）。本系统是一个小型音乐喷泉控制系统,它以PLC为控制核心，变频器控制水柱高度，以音频采集为基础，同时PLC程序控制灯光的亮灭和颜色的变化。本系统选用SIEMENS公司的S7-200PLC为控制核心，选用MicroMaster440（简称MM440）变频器控制水泵高度，达到喷泉的立体效果随音乐变换而变化。本系统主要包括PLC的选型（CPU226）、PLC的扩展模块（EM222）、I/O地址的分配、输入输出接口的连接和梯形图的绘制，梯形图绘制是重点，同时着重介绍了MM440变频器的变频原理、参数设置和变频器与PLC和电动机的接口连接。系统设计完成后，能够达到中心、内圈、外圈共三圈喷头喷水，变频器控制内圈喷头改变水柱高度，PLC控制余下喷头有序启动停止，同时夜晚有三层灯光变幻，能够实时展现音乐的动态美。关键词：音乐喷泉,控制系统，可编程控制器，梯形图，变频器青岛理工大学毕业设计（论文）IIABSTRACTInanumberoflandscapearchitecture,thedesignoflargepublicbuildingsandtouristbuildings,designersoftenfountainintheformofanartintegrationinthebuilding,givingtothebeautyofnature.Alongwithregularmusicplayernozzlesprayandlightsaregularlightoff(thelaw,includingthesizeofthemusictunesandmusicsound),toachievethecontroleffectoflight(daylightdoesnotshine,nightlightaregularlightoff).Thissystemisasmallmusicalfountaincontrolsystem,whichPLCasthecontrolcore,invertercontrolcolumnheighttoaudiocapture-basedPLCprogramcontrolwhilethebrightlightsoffandcolorchanges.ThesystemselectedcompanySIEMENSS7-200PLCasthecontrolcore,thechoiceMicroMaster440(referredMM440)invertercontrolpumpheightandreachfountainstransformthree-dimensionaleffectvarieswiththemusic.ThesystemincludesPLCSelection(CPU226),PLCexpansionmodule(EM222),I/Oaddressallocation,input-outputinterfaceconnectionsanddrawladder,ladderdrawingisthekey,whilehighlightingMM440invertertheinverterprinciple,parametersettingsandthemotorandinverterandPLCinterfaceconnection.Systemdesigniscomplete,itcanreachthecenter,theinnerandouterringsofnozzlesspraythreetimes,theinvertercontrolinnernozzlechangecolumnheight,PLCcontrolstartandstoptheremainingnozzles,whileatnighttherearethreelightchanges,real-timedisplayofmusicdynamicbeauty.KEYWORDS:musicalfountain,controlsystem,PLC,LAD，Transducer青岛理工大学毕业设计（论文）III目录摘要...............................................................................................................................IABSTRACT..................................................................................................................II第1章绪论................................................................................................................11.1课题背景..........................................................................................................11.1.1音乐喷泉的发展历程............................................................................11.1.2音乐喷泉的现状....................................................................................21.2课题研究内容..................................................................................................2第2章PLC基础知识.................................................................................................42.1PLC的产生和发展..........................................................................................42.2PLC的特点和功能..........................................................................................42.3PLC的基本结构和工作原理..........................................................................5第3章变频器基础知识..............................................................................................73.1变频器概述......................................................................................................73.2变频器的分类..................................................................................................73.3变频器的工作原理及控制方式......................................................................73.3.1变频器的工作原理................................................................................73.3.2变频器的控制方式................................................................................83.4MM440变频器................................................................................................9第4章系统方案分析及可行性分析........................................................................114.2方案论证........................................................................................................124.3对选定方案的分析........................................................................................13第5章系统总体设计................................................................................................145.1音乐喷泉组成................................................................................................145.1.1音乐喷泉水池设计..............................................................................145.2控制系统组成................................................................................................175.3变频器设计....................................................................................................185.3.1变频器选型..........................................................................................185.3.2变频器控制接线图..............................................................................185.3.3变频器参数设置..................................................................................195.4PLC设计.......................................................................................................
