毕业设计（论文）-基于AT89C51单片机的全自动洗衣机控制系统设计.doc

摘要

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AT89C51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、洗涤、漂洗、脱水和结束报警等阶段。控制系统主要由电源电路、单片机控制系统和外部硬件电路三大模块组成。电源电路为单片机主控系统提供5v的直流电压;单片机主控系统负责控制洗衣机的正常工作由AT89C51单片机构成;外部硬件电路由液晶显示屏、单相异步电机、进水出水阀门、负载水位传感器、蜂鸣器等组成。本系统运用keil软件对单片机进行编程,再编译成hex文件后,通过proteus仿真软件进行仿真,从而实现预期的效果。

Abstract
With the development of the digital technology, digital technology has been widely applied in the field of intelligent control. MCU with small volume, complete functions, low price, convenient development advantage by many electronic system designers favor. It is suitable for real-time control, can form industrial controllers, intelligent instruments, intelligent interface, intelligent weapon device and universal measurement and control unit.
Based on the AT89C51single-chip puter as the core design of the full automatic washing machine control system, this system realizes the washing machine the whole washing process control, including user parameter input, wash, rinse, dehydration and the end of alarm level. The control system is posed of a power circuit, SCM control system and the external hardware circuit posed of three modules. Power supply circuit for single-chip puter control system with 5V DC voltage; single-chip puter control system controls the normal work of the washing machine based on AT89C51 MCU; external hardware circuit posed of liquid crystal display screen, single asynchronous motor, water inlet and outlet valve loadandwaterlevelSensor sensor, buzzer, etc.. The system using keil software for single-chip programming, and piled into a hex file, through proteus simulation software, in order to achieve the desired effect.
Key words puter Loadandwaterlevelsensor LCD Singleasynchronous motor
