基于组态王-PLC的轮胎硫化温度、压力控制系统设计摘要近年来，随着我国汽车工业的发展，与之处于同一产业链的轮胎工业也得到了相应的提高，轮胎呈现出种类数目不断增多与剂型不断丰富的局面。轮胎硫化过程是轮胎制造过程中的一道重要工序，其硫化效果是影响轮胎质量的关键因数之一。在轮胎硫化过程中温度和压力是两个重要指标。轮胎硫化控制系统，分为上位机和下位机，上位机采用的是国内的一个比较流行的组态王软件。组态王可以实现在线监控。组态项目中制作了曲线画面、报表画面、报警画面和参数监控画面，用户可方便地查询PLC的运行情况、数据采集和在线控制。下位机采用PLC控制。PLC可独立的实现对两套硫化系统的控制。硫化中的温度数据有铂热电阻Pt100采集来后，经EM231转换，再送到CPU224。压力数据有压力表采集后，经EM235，送CPU224。关键字：温度压力控制；可编程控制器；PID；组态王；TirecuringtemperatureandpressurecontrolsystembasedonkingView-PLCAbstractInrecentyears,asChina'sautomobileindustrydeveloping,withthesamechaininthetireindustryhasalsobeenacorrespondingincreaseintireshowingagrowingnumberoftypesofformulationsenrichedwiththesituation.Tirevulcanizingtiremanufacturingprocessisanimportantstepintheprocess,andthecuringeffectisthekeyfactoraffectingthequalityofthetire.Temperatureandpressureinthetirecuringprocessaretwoimportantindicators.Tirecuringcontrolsystemisdividedintoupperandlowermachine,andthePCusesamorepopulardomesticConfigurationsoftware--KingView.KingViewcanbeachievedonlinemonitoring.Projectproducedacurveconfigurationscreens,reportsscreen,alarmscreenandparametermonitoringscreen,anduserscaneasilychecktheoperationofthePLC,dataacquisitionandonlinecontrolling.LowerpositionmachineusesPLCcontroling.PLCcanachieveindependentcontrollingoftwovulcanizationsystem.VulcanizationtemperaturedataarecollectedtoplatinumRTDPt100,throughEM231conversion,anditthencansenttotheCPU224.Gaugepressuredataarecollected,throughEM235,sendingtoCPU224.Keywords:Temperatureandpressurecontrol;programmablecontroller;PID;kingview;目录摘要.............................................................IAbstract.................................................................II第一章轮胎硫化的概述...................................11.1轮胎硫化的背景.....................................11.2轮胎硫化的工艺要求..............................11.2.1技术参数和硫化曲线.........................11.3轮胎硫化的方式、方法及步骤................21.3.1轮胎硫化的方法................................21.3.2轮胎硫化的方式................................21.3.3轮胎硫化的步骤................................31.4硫化过程的主要问题..............................4第二章系统的总设计及人机界面.....................62.1系统总原理图........................................62.2人机界面介绍........................................62.2.1人机界面概述...................................62.2.2人机界面定义...................................72.2.3人机界面产品的组合及工作原理.......72.2.4人机界面产品的特点.........................7第三章硬件配置..............................................83.1设备生产线要求.....................................83.2实验配置...............................................83.2.1西门子S7-200.......................................83.3可编程控制器PLC概述..............................83.3.1PLC特点..............................................93.4PLC的结构..............................................103.4.1CPU的构成........................................103.4.2I/O模块..............
