基于PLC的电镀生产线控制系统设计

洛阳理工学院毕业设计（论文）I基于PLC的电镀生产线控制系统设计摘要本文讨论了如何利用德国西门子PLCS7-200进行自动化电镀生产线控制，在本次设计中，我们从自动控制技术器件在国内的应用前景及电镀生产线生产现场的环境来考虑，以使该生产线真正具备自动生产运行为目的，从而采用在当前及以后都应用广泛且能适应多种环境的可编程控制器来控制整个工作流程的方案。重点分析了系统软硬件设计部分，并给出了系统硬件接线图、PLC控制I/O端口分配表以及整体程序流程图等，实现了电镀生产自动化，提高了生产效率，降低了劳动强度，大大提高了工作人员的工作环境质量。为适应现代传统的工业控制系统，还采用了基于组态王软件的系统作为上位机，配合下位机PLC完成了该系统的实时监控系统功能，更好的使该自动生产系统融入到现代工业控制领域中。关键词：PLC，电镀，组态王洛阳理工学院毕业设计（论文）IIDesignofGalvanizationProductionLineControlSystemBasedonPLCABSTRACTThisarticlediscussedhowcarriedontheautomatedgalvanizationproductionlinecontrolusingGermanSiemensPLCS7-200.Inthisdesign,wetakeconsideroftheautomaticcontroltechnologycomponentinthedomesticapplicationprospectandtheenvironmentofthegalvanizationproductionline,andthismakesthisproductionlinetrulytohavetheautomaticproductionmovementasthegoal.Weformulateaplanthatusesaprogrammablecontrollerwhichcanadaptmanykindsofenvironmentincurrentandlatertocontroltheentirework.Weanalyzedthesystemsoftwareandhardwaredesignwithemphasis,andprovidethesystemhardwarewiringdiagram,PLCI/Oportdistributionlistandtheoverallprogramflowdiagramandsoon.Thisdesignrealizedthegalvanizationproductionautomation,enhancedtheproductefficiency,andreducedthelaborintensity.Inordertoadaptthemoderntraditionindustrycontrolsystem,wealsousedtheKingViewsoftwaresystemwhichhadtakenonasthepositionmachine.AndcoordinatePLCaslowerpositionmachine.Allthishasmadethissystemhadthefunctionofcurrenttimemonitoring.Thatcausedthisautomaticproductionsystemintegratetothemodernindustrycontrolsystembetter.KEYWORDS:PLC,Galvanization,KingView洛阳理工学院毕业设计（论文）III目录前言................................................................................................1第1章绪论......................................................................................21.1控制系统概述与选题背景意义............................................21.1.1控制系统的概述.........................................................21.1.2课题的选题背景及意义..............................................21.2控制对象的设计要求...........................................................31.3PLC系统组成......................................................................41.3.1CPU..............................................................................41.3.2存储器.........................................................................41.3.3输入/输出接口电路....................................................41.4PLC的基本工作原理...........................................................51.5小结......................................................................................5第2章系统的硬件设计...................................................................62.1主电路设计...........................................................................62.2PLC机型选择.......................................................................72.3I/O分配表及其端子接线图..................................................72.3.1I/O地址分配................................................................72.3.2PLC外部接线图..........................................................82.4小结......................................................................................9第3章系统的软件设计.................................................................103.1软件的组成及作用.............................................................103.1.1PLC内部资源............................................................103.1.2PLC编程语言............................................................113.2程序流程图设计.................................................................123.3程序梯形图设计.................................................................133.4指令表................................................................................153.5小结....................................................................................18第4章系统组态画面设计.............................................................19洛阳理工学院毕业设计（论文）IV4.1组态软件介绍.....................................................................194.2监控画面设计.....................................................................204.2.1建立新工程...............................................................204.2.2创建组态画面...........................................................224.2.3定义I/O设备............................................................244.2.4构造数据库...............................................................274.2.5动画连接...................................................................294.2.6编写语言命令...........................................................304.3小结....................................................................................31第5章系统软硬件调试.................................................................32结论..............................................................................................37谢辞..............................................................................................38参考文献..........................................................................................39外文资料翻译..................................................................................40洛阳理工学院毕业设计（论文）1前言本设计的工作过程是这样的：在电镀生产线左侧，工人将零件装入行车的吊篮并发出自动启动信号，行车提升吊篮并自动前进。按工艺要求在需要停
