全自动洗衣机毕业设计全自动洗衣机毕业设计摘要洗衣机从20世纪80年代初期开始传入中国家庭，并由最初的单缸洗衣机到双缸洗衣机，再到全自动洗衣机。
全自动洗衣机也从最初的采用机械电动式控制器的普通式全自动洗衣机，发展到采用微电脑控制的微电脑控制全自动洗衣机，再到采用模糊控制技术的模糊控制全自动洗衣机。
全自动洗衣机是一种同时具有洗涤、漂洗和脱水等功能，且它们之间的转换不用手工操作而能知道进行的洗衣机。
随着数字技术的快速发展，数字技术被广泛应用于智能控制的领域中。
单片机以体积小、功能全、价格低廉、开发方便的优势得到了许多电子系统设计者的青睐，它适合于实时控制，可构成工业控制器、智能仪表、智能接口、智能武器装置以及通用测控单元等。
本文以AT89S52单片机为核心，设计了全自动洗衣机控制系统。
本系统实现了对洗衣机整个洗衣过程的控制，包括用户参数输入、洗衣、脱水和结束演奏四个阶段。
控制系统主要由电源电路、数字控制电路和机械控制电路三大模块构成。
电源电路为数字控制电路提供稳定的5V直流电压，为电动机提供220V市电；数字控制电路负责控制洗衣机的工作过程，主要由AT89S52单片机、两位共阴数码管、按键、蜂鸣器、LED指示灯组成；机械控制电路实现水位检测、电机驱动、进水、排水等功能，主要由水位检测器、电动机、传动系统部件、进水排水电磁阀组成。
本系统的电路并不复杂，给AT89S52单片机载入软件程序后，能够实现全自动洗衣机的基本功能。
虽然不能与电器市场上的洗衣机控制系统媲美，但也具有一定的实用性。
关键词：AT89S52单片机洗衣机控制摘要ABSTRACTThe washer has streamed into Chinese family since the early part of 80's in 20th century, and from the first single urn of washer arrive a double urn washer, arrive adoption faintness to control technical of the faintness control a full-automatic washer.The full-automatic washer is 1 kind to have rinse and Piao to wash and dehydrate etc. function at the same time, and their arrive a full-automatic washer again.Full-automatic washer also the common type from the first adoption machine dynamoelectric type controller full-automatic washer, develop to adopt the micro-computer of the control of micro-computer to control a full-automatic washer, again conversion need not handicraft operation but can know to carry on of washer.Along with the rapid development of number technique, the number technique is extensively been applied to the realm of the control of intelligence in.List slice machine with the favor that the physical volume is small, whole function and cheap price and developed convenient advantage to get many electronics system designs, it controled while being suitable for solid, can constitute industrial controller, intelligence gauge and intelligence to connect , intelligence weapon device and in general use etc. for measuring to control unit.This text with the AT89 S52 list slice machine for core, designed the full-automatic washer control system.This system carried out the whole control that does laundry process to the washer and included a customer parameter importation, do laundry, dehydration and be over give musical performance four stages.Control system mainly the electric circuit and machine control electric circuit from the power electric circuit, number control three greatest mold the piece constitute.The power electric circuit controls electric circuit to provide stable 5 V direct current毕业论文electric voltage for number and provides the 220 V City the electricity for electric motor;The number control electric circuit is responsible for the work process that controls a washer, is mainly taken care of by the AT89 S52 list slice machine, two total Yin figureses, key, buzzer and LED the indicator constitute;The machine control electric circuit carries out water level examination, electrical engineering to drive, enter functions, such as water and catchment...etc., mainly from water level detector, electric motor, spread a system parts and enter water catchment electromagnetism valve to constitute.The electric circuit of this system isn't complicated, after giving the AT89 S52 single slice of machine to load in software procedure, can carry out the basic function of full-automatic washer.Although not ability and the washer in the electric appliances market controls system to match in excellence,also has certain function.Keyword:The AT89 S52 list slice machine washer controls目录摘要 (1)前言 (3)第一章绪论 (4)1.1设计任务及要求 (4)1.2 洗衣机的发展和分类 (4)1.2.1 洗衣机的发展史 (4)第二章总体设计方案 (9)2.1 方案论证与比较 (9)2.1.1控制系统的选择 (9)2.1.2水位检测 (10)2.1.3电动机驱动电路 (10)2.1.4显示模块 (10)2.1.5进水与出水电路 (11)2.2 控制系统的功能 (11)2.3 洗衣机的控制过程： (12)第三章硬件设计 (14)3.1 电源电路部分 (14)3.2 数字控制电路 (15)3.2.1 AT89S52单片机主控模块 (15)3.2.2 数码管显示模块 (18)3.2.3 按键输入模块 (20)3.2.4 蜂鸣器报警模块 (20)3.2.5 LED指示模块 (21)3.3 水位检测器 (22)3.3.1 电动机 (22)3.3.2 7407缓冲器和MOC3061（光耦） (23)3.3.3 进水/排水电磁阀 (24)第四章软件设计 (25)4.1 单片机I/O口分配： (25)4.2 程序流程 (26)4.3 源程序 (26)4.4 程序运行过程分析 (26)第五章硬件、软件调试 (28)5.1硬件调试 (28)5.2软件调试 (29)第六章总结 (30)致谢 (31)参考文献 (32)附录 I (34)附录 (40)前言前言随着生活水平的提高和生活节奏的加快，洗衣机作为一种代替人们手工洗涤衣服的家用电器已成为我们生活中不可缺少物品。
随着科学技术的发展，洗衣机的性能的不断提高，产品不断更新换代，最早的洗衣机是人工驱动的搅拌式，后来采用机械驱动，成为现代洗衣机。
近年来随着人类与环境问题和资源问题的尖锐化，人们的环保意识和节能意识的不断提高，环保和节能的洗衣机越来越受到人们的青睐，成为洗衣机的发招趋势。
单片机以微小的体积和编程的灵活性而产生多种控制功能,完全可以满足家用电器的需求。
单片机又称微控制器,或称嵌入式控制器。
而现在的智能家电无一例外是采用微控制器来实现的,所以家用电器是单片机应用最多的领域之一。
它是家用电器实现智能化的心脏和大脑。
