基于FR-S540通用变频器的三翼自动旋转门控制系统设计I摘要随着科学技术的不断发展，三翼旋转门系统已开始应用于大型公司、科研所、政府机关等保密性较强的单位。为增强三翼旋转门运行的可靠性，本设计提出了一种SIMATIC-S7-200可编程控制器（PLC）与变频器控制的三翼旋转门控制系统，设计中采用两个感应探测器（门内和门外）、一些开关及传感器作为此系统的输入设备，变频器用来调节门体速度，并分析了该控制系统的工作原理及系统的硬件组成，分析了人体感应探测、三翼旋转门运行位置检测、门运行障碍检测等控制电路的工作过程，对PLC的选型、变频器的选型、I/O点的确定及三翼旋转门的动作过程等方面进行了详细阐述。结合PLC的运行特点，对控制系统的工作流程作了合理的优化。在此基础上，给出了控制系统软件设计的程序流程图、顺序功能图、外部端子接线图及PLC控制梯形图等。本设计介绍应用可编程控制器取代传统的继电器、接触器控制系统，实现三翼旋转门控制的过程。关键词三翼旋转门，可控制编程器，梯形图，变频控制沈阳工程学院毕业设计（论文）IIAbstractWiththecontinuousdevelopmentofscienceandtechnology,automaticdoorsystemhasbeenappliedtolargecompanies,researchinstitutes,governmentagenciesandotherunitsarehighlyconfidential.Toenhancethereliabilityofautomaticdooroperation,thisdesignpresentsaFX2-32MRprogrammablelogiccontroller(PLC)andtheinvertercontrolautomaticdoorcontrolsystem,thedesignusestwosensorprobes(dooranddooroutside),someswitchesandsensorsasthesysteminputdevice,thedrivedoorisusedtoadjustthespeed,andanalyzestheworkingprincipleofthecontrolsystemhardwarecomponentsandsystems,analysisofthehumanbodydetectionsensors,automaticdooroperationpositiondetection,thedoorobstacledetectionandothercontrolcircuittoruntheworkingprocess,theselectionofthePLC,inverterselection,I/Opointsoftheactiontoidentifyandautomaticdoorsandotheraspectsoftheprocessindetail.WithPLC'soperatingcharacteristicsofthecontrolsystemwerereasonableworkflowoptimization.Onthisbasis,giventheprocesscontrolsystemsoftwaredesignflow,sequentialfunctionchart,theexternalcontrolterminalwiringdiagramandPLCladderandsoon.Describestheapplicationoftheprogrammablecontrollerdesignedtoreplacetraditionalrelay,contactorcontrolsystems,automaticdoorcontrolprocess.KeyWords:AutomaticDoors，ControlProgramming，Ladder，Drive基于FR-S540通用变频器的三翼自动旋转门控制系统设计目录摘要.....................................................................................................................................................................IAbstract................................................................................................................................................................II1引言..............................................................................................................................................................-1-1.1研究的背景和意义......................................................................................................-1-1.2国内外三翼旋转门的发展状况..................................................................................-2-1.3三翼旋转门技术发展方向..........................................................................................-2-1.4三翼旋转门研究的必要性..........................................................................................-3-2三翼旋转门控制系统总体方案设计..........................................................................................................-4-2.1三翼旋转门系统的基本结构......................................................................................-4-2.2三翼旋转门控制要求..................................................................................................-5-2.3三翼旋转门控制方案的确定......................................................................................-5-3自动门硬件系统的设计..............................................................................................................................-6-3.1PLC的简要介绍...........................................................................................................-6-3.2PLC的选型...................................................................................................................-7-3.3PLC的I/O点分配.......................................................................................................-7-3.4电动机的选型..............................................................................................................-8-3.5变频器容量选择..........................................................................................................-8-3.6三翼旋转门控制系统原理简述..................................................................................-9-4变频器的参数设定及功能选择................................................................................................................-10-4.1变频调速的基本原理................................................................................................-10-沈阳工程学院毕业设计（论文）4.2三菱FR-540变频器的面板......................................................................................-10-4.2三菱变频器FR-540端口介绍和连线方法..............................................................-12-4.3功能（参数）介绍....................................................................................................-14-5系统软件部分设计....................................................................................................................................-16-5.1三翼旋转门的功能需求分析....................................................................................-16-5.2变频器输出频率与控制端子关系曲线....................................................................-17-5.3PLC控制系统程序.....................................................................................................-17-5.4旋转门运行状态诊断程序............
