基于单片机全自动洗衣机控制系统 摘 要 伴随数字技术快速进展，数字技术被广泛应用于智能控制领域中。单片机以体积小、功效全、价格低廉、开发方便优势得到了许多电子系统设计者青睐。它适合于实时控制，可组成工业控制器、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 AT89S51 单片机为关键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控制，包含用户参数输入、洗衣、脱水和结束报警四个阶段。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 直流电压；单片机主控系统负责控制洗衣机工作过程，主要由 AT89S51 单片机、数码管、按键、蜂鸣器、LED 指示灯组成；外部硬件电路有继电器、三极管、LED 灯组成。 本系统电路并不复杂，给 AT89S51 单片机载入软件程序后，能够实现全自动洗衣机基本功效。即使不能与电器市场上洗衣机控制系统媲美，但也具备一定有用性。 关键词： AT89S51 ；用户参数；继电器；控制系统； LED 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 fo smallness, full function, low price and easy application. Its pretty fit for real-time a core in industrial controller, intelligent apparatus, intelligent interface, intell device, universal measure control unit, etc. This article designs a full-automatic washing machine control system with AT89S51 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 ci and machine control circuit. Power supply circuit provides steady DC 5V voltage for di control circuit and AC 220V for motor. Digital control circuit takes charge of control working course. It consists of AT89S51, double-figured common-cathoded numeral dis...
