摘 要
隨著數(shù)字技術(shù)的快速發(fā)展，數(shù)字技術(shù)被廣泛應(yīng)用于智能控制的領(lǐng)域中。單片機以體積小、功能全、價格低廉、開發(fā)方便的優(yōu)勢得到了許多電子系統(tǒng)設(shè)計者的青睞，它適合于實時控制，可構(gòu)成工業(yè)控制器、智能儀表、智能接口、智能武器裝置以及通用測控單元等。
本文以AT89S51單片機為核心，設(shè)計了全自動洗衣機控制系統(tǒng)。本系統(tǒng)實現(xiàn)了對洗衣機整個洗衣過程的控制，包括用戶參數(shù)輸入、洗衣、脫水和結(jié)束演奏四個階段。控制系統(tǒng)主要由電源電路、數(shù)字控制電路和機械控制電路三大模塊構(gòu)成。電源電路為數(shù)字控制電路提供穩(wěn)定的5V直流電壓，為電動機提供220V市電；數(shù)字控制電路負責(zé)控制洗衣機的工作過程，主要由AT89S51單片機、兩位共陰數(shù)碼管、按鍵、蜂鳴器、LED指示燈組成；機械控制電路實現(xiàn)水位檢測、電機驅(qū)動、進水、排水等功能，主要由水位檢測器、電動機、傳動系統(tǒng)部件、進水排水電磁閥組成。
本系統(tǒng)的電路并不復(fù)雜，給AT89S51單片機載入軟件程序后，能夠?qū)崿F(xiàn)全自動洗衣機的基本功能。雖然不能與電器市場上的洗衣機控制系統(tǒng)媲美，但也具有一定的實用性。

ABSTRACT
With its rapid development, digital technology is widely used in the field of control system. Single chip microcontroller is favored by many electronic system designers for its smallness, full function, low price and easy application. It’s pretty fit for real-time control as a core in industrial controller, intelligent apparatus, intelligent interface, intelligent weapon device, universal measure control unit, etc..
This article designs a full-automatic washing machine control system with AT89S51 as core. This system realizes whole working course of full-automatic washing machine, including four parts: user parameter input, wash, dehydrate and ending music play. Hardware system is made up of three modules: power supply circuit, digital control circuit and machine control circuit. Power supply circuit provides steady DC 5V voltage for digital control circuit and AC 220V for motor. Digital control circuit takes charge of controlling the working course. it consists of AT89S51, double-figured common-cathoded numeral display, buttons, buzzer, LEDs. Machine control circuit realizes the functions of water level detect, motor driven, water import and export, it consists of water level detector, motor, transmission system components and penstocks.
After downloading the program to AT89S51, this circuit can realize basic functions of full-automatic washing machine. It seems hard for this control system to compare with perfect ones in the electrical appliance market, but it has certain practicability.
