摘要本文描述了采用可编程控制器(PLC)作为核心控制部件,并利用计算机进行模拟监控的全自动洗衣机控制系统。文章介绍了洗衣机的结构,对全自动洗衣机的控制系统进行了分析在此基础上提出了基于PLC的全自动洗衣机控制方案,并对方案进行了论证,根据洗衣机的工作原理,设计了流程及程序,对按钮,等其它一些输入/输出点进行控制,实现了洗衣机洗衣过程的自动化。由于洗涤,排水,脱水的时间均由PLC内计数器控制,所以只要改变计数器参数就可以改变时间。具有智能化程度高、安全可靠、方便、灵活,丰富的I/O卡件,质优价廉,性价比高,安装简单,维修方便,PLC控制能在高粉尘、高噪声、强电磁干扰和温度变化剧烈的环境下正常工作。因为它是整体模块,集中了驱动电路、检测电路和保护电路以及通讯联网功能,所以在使用中,硬件相对简单,编程语言也相对简单,并且测试容易,维修方便,更可以提高控制系统设计的灵活性及控制系统的可靠性。本设计以操作简单、使用可靠、维护修理方便作为主要设计方向。关键词:可编程控制器,PLC,全自动洗衣机AbstractThispaperdescribesanautomaticwashingmachinecontrolsystemwithPLCasthecorecontrolcomponentandcomputersimulationmonitoring.Thispaperintroducesthestructureofthewashingmachine,fullyautomaticwashingmachinecontrolsystemisanalyzed,onthebasisoffullyautomaticwashingmachinecontrolschemebasedonPLCwasproposed,andtheschemewasdemonstrated,accordingtotheworkingprincipleofthewashingmachinedesignprocessandprocedures,thebutton,suchassomeotherinput/outputpointtocontrol,realizetheautomationofthewashingmachinewashingprocess.Aswashing,drainage,dehydrationtimebythePLCcountercontrol,soaslongasthechangeofcounterparameterscanchangethetime.Withahighdegreeofintelligence,safeandreliable,convenient,flexible,richI/Ocardparts,qualityandcheap,cost-effective,simpleinstallation,easymaintenance,PLCcontrolcanbeinthehighdust,highnoise,strongelectromagneticinterferenceandtemperaturechangesintheenvironment.Becauseitisanintegralmodule,focusingonthedrivercircuit,detectioncircuitandprotectioncircuitandcommunicationnetworkfunctions,soinuse,thehardwareisrelativelysimple,theprogramminglanguageisrelativelysimple,andtestingiseasy,easymaintenance,butalsocanimprovetheflexibilityofcontrolsystemdesignandcontrolsystemreliability.Thedesigntosimpleoperation,reliableuse,easymaintenanceandrepairasthemaindesigndirection.Keywords:Programmablecontroller,PLC,automaticwashingmachine目录第1章绪论.............................................................1第2章全自动洗衣机控制系统总体控制方案确定.ERROR:REFERENCESOURCENOTFOUND2.1总体控制方案确定.............................ERROR:REFERENCESOURCENOTFOUND2.1.1控制系统的比较...................Error:Referencesourcenotfound2.2.2洗衣机的PLC控制系统概述.........Error:Referencesourcenotfound2.2.3PLC的设计步骤...................................................3第3章全自动洗衣机的基本结构.....................................................53.1全自动洗衣机的原理和构造................................................53.2洗涤脱水系统............................................................73.3排水和进水系统..........................................................73.4电动机及传动系统........................................................8第4章电气控制系统................................................................104.1控制系统结构...........................................................104.2控制系统原理...........................................................104.3主电路图.....................................................
