本科生毕业设计说明书（毕业论文）题目：基于PLC的全自动洗衣机控制系统设计学生姓名：学号：20专业：电气工程及其自动化班级：电气1班指导教师：李授I基于PLC的全自动洗衣机控制系统摘要本文是利用可编程控制器PLC实现了对洗衣机的全自动控制，且说明了PLC控制的原理方法，优点和特点及控制洗衣机的特色。本文在介绍了洗衣机结构的同时，又对全自动洗衣机的控制系统进行了非常全面分析，并在此基础上提出基于PLC的全自动洗衣机控制方案，且对实施方案进行了论证,根据洗衣机的工作原理从而对程序及其流程进行了设计,该系统具有智能化程度高、安全可靠和运行稳定等特点。对电磁阀，按钮,开关等其它一些输入/输出点进行控制，从而实现了洗衣过程的自动化，并实现了多台控制。由于每遍的洗涤、排水、脱水的时间由PLC内定时器控制，所以只要改变定时器参数就可以改变相应的控制时间。关键词：可编程序控制器（PLC）;自动控制;变频器;洗衣机内蒙古科技大学毕业设计说明书（毕业论文）IIPLCintheapplicationoffull-automaticwashingmachineAbstractThispaperistheuseofprogrammablecontrollerPLCrealizestheautomaticcontrolofthewashingmachine,butyouaskcleartheprincipleofPLCcontrolmethod,theadvantagesandcharacteristicsandthecontrolcharacteristicofthewashingmachine.Thisarticleintroducesthestructureofthewashingmachineatthesametime,andfullyautomaticwashingmachinecontrolsystemfortheverycomprehensiveanalysis,andonthebasisoffullyautomaticwashingmachinecontrolschemebasedonPLCisputforward,andtheimplementationplan,accordingtothewashingmachineworkingprincipleandapplicationanditsprocessofdesign,thesystemhasahighintelligentdegree,safeandreliableandstableoperation,etc.Someofsolenoidvalves,buttons,switchesandotherinput/outputpointtocontrol,soastorealizetheautomationofthewashingprocess,andmanysetsofcontrolcouldbeachieved.Becauseeverytimewash,drainageanddehydrationtimetimercontrolbyPLC,sojustchangethetimerparameterscancontroltimeaccordingly.Keywords:programmablecontroller(PLC);Theautomaticcontrol;Theinverter;Thewashingmachine内蒙古科技大学毕业设计说明书（毕业论文）III目录摘要.............................................................................................................................................IAbstract......................................................................................................................................II第一章绪论..............................................................................................................................51.1课题背景与意义........................................................................................................51.2全自动洗衣机简介....................................................................................................61.3全自动洗衣机控制技术的现状与发展....................................................................81.4本文主要的工作........................................................................................................9第二章概述............................................................................................................................102.1PLC的控制特点.......................................................................................................102.2控制系统框图..........................................................................................................112.3控制系统对应设备及功能......................................................................................12第三章硬件的设计................................................................................................................133.1外部设备的选择......................................................................................................133.2变频器......................................................................................................................143.3电动机......................................................................................................................163.4可编程控制器的选择..............................................................................................183.5PLC外部接线图.......................................................................................................19第四章软件的设计................................................................................................................254.1I/O分配表..............................................................................................................254.1.1输入地址分配表............................................................................................254.1.2输出地址分配表............................................................................................26内蒙古科技大学毕业设计说明书（毕业论文）IV4.1.3内部元件地址分配表....................................................................................274.2系统流程图..............................................................................................................284.2.1强制停止流程图............................................................................................284.2.2正常运行流程图............................................................................................284.2.3去抖动程序流程图........................................................................................304.3程序设计..................................................................................................................304.3.1PLC控制顺序功能图.....................................................................................304.3.2系统梯形图....................................................................................................314.3.3系统指令语句表............................................................................................39第五章程序运行过程分析........................
