毕业设计(论文)题目:基于西门子PLC200及组态王的配料生产线控制系统设计(英文):DesignofIngredientsProductionLineControlSystemBasedonSiemensPLC200andKingview院别:自动化学院专业:电气工程及其自动化姓名:xxx学号:xxx指导教师:xxx日期:2012年5月基于西门子PLC200及组态王的配料生产线控制系统设计摘要随着社会的进步、科技日新月异,从18世纪60年代的以蒸汽机为主要动力的工业革命开始直到现在,工业的生产线经历过了300多年的发展历史,已经发展到了今天的全自动化大批量生产。可以说现代工业已经离不开自动化的生产线了,自动化生产线不仅可以大幅度地提高生产效率,而且还可以提高精度、提高合格率、减轻人的工作量等好处。在工业如此发达的今天,生产线控制系统逐渐地由PLC控制代替原来的单片机或机械电气控制,其许多功能是传统的控制技术无法实现的。本设计针对我国一些小型企业的配料生产线控制系统现状,将西门子S7-200系列的PLC应用于小型的配料生产线,再由组态王作为人机交互的界面作为远程控制和监控作用。本设计通过合理的选择和编程,不仅可以提高配料生产线的生产效率、降低成本、提高安全可靠性,还可以根据不同的配料合理调整PLC程序的参数,而且可以直接通过组态王监控、控制和调整参数,实现远程控制,提高人性化。关键词:生产线;PLC;组态王DesignofIngredientsProductionLineControlSystemBasedontheSiemensPLC200andKingviewABSTRACTWiththeprogressofsocietyandthegreatchangesofscienceandtechnology,fromthe1760swhenthesteamengineisactedasthemainpowerofthebeginningoftheindustrialrevolutiontonow,industrialproductionlineshaveexperienced300-yeardevelopmentalhistory,andhasdevelopedintofullyautomatedmassproductioncurrently.Itcanbesaidthatmodernindustryhasbeeninseparablefromtheautomatedproductionline.Automaticproductionlinenotonlycangreatlyimprovetheproductionefficiency,butalsocanimprovetheprecision,boostqualifiedrate,reducetheworkload.Nowadaysindustryisdeveloped,andproductionlinecontrolsystemisrgraduallyreplacedtheoriginalsinglechipcomputerorelectricalmachinerycontrolwiththePLCcontrol.Manyofitsfunctionscannotbeachievedjustthroughtraditionalcontroltechnology.Thispaperaimstosmallbusinessingredientproductionlinecontrolsysteminourcountry,andapplysthePLCofSiemensS7-200seriestosmallbatchproductionline,andtreatskingviewasahuman-computerinteractioninterfaceforremotecontrolandmonitoringfunction.Thispaperthroughthereasonableselectionandprogramming,cannotonlyimprovethebatchingproductionefficiency,reducethecost,improvethesafetyandreliability,andmakereasonableadjustmentofPLCprogramparametersaccordingtothedifferentingredients,butalsocandirectlyviathekingview'smonitor,controlandadjustmentofparameters,torealizetheremotecontrolandimprovehumanization.Keywords:ProductionLine;PLC;Kingview目录1绪论.........................................................................................................................................11.1配料生产线的发展概括..................................................................................................11.2单片机控制系统特点与存在问题..................................................................................21.3PLC控制配料生产线的特点..........................................................................................21.4组态王的特点..................................................................................................................31.5课题研究的意义和目的..................................................................................................42可编程逻辑控制器(PLC)概要...........................................................................................52.1PLC简介..........................................................................................................................52.2可编程控制器(PLC)的特点............................................................................................52.2.1硬件的可靠性............................................................................................................52.2.2编程简单,使用方便...............................................................................................62.2.3接线简单,通用性好...............................................................................................62.2.4可连接为控制网络系统............................................................................................62.2.5易于安装,便于维护...............................................................................................72.3PLC的硬件结构..............................................................................................................72.3.1中央处理单元(CPU)...........................................................................................72.3.2存储器(RAM、ROM).........................................................................................82.3.3输入输出单元(I/O单元).....................................................................................82.3.4电源............................................................................................................................82.3.5编程器........................................................................................................................92.4PLC的工作原理..............................................................................................................93配料生产线系统分析...........................................................................................................103.1配料生产线系统的概述与分类....................................................................................103.2配料生产线系统的组成.................................................................................................113.3配料生产线的控制要求................................................................................................123.4配料生产线控制系统的流程图.........................................................
