基于AT89C51的全自动洗衣机摘 要随着数字控制技术的快速发展，其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。近年来，单片机的应用不断走向深入，同时带动传统控制检测日益更新。在实时检测和自动控制的单片机应用系统中，单片机往往作为一个核心部件使用，并需根据具体硬件结构，针对具体应用对象特点设计软件，以实现实时控制。本文以AT89C51单片机为核心，设计了全自动洗衣机的控制系统。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、脱水和停机四个阶段。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AT89C51单片机、六位共阴数码管、按键、蜂鸣器、LED指示灯等组成；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、进水排水电磁阀等组成。本文编写的主导思想是软硬件相结合，以硬件为基础，进行各功能模块的程序编写，具有一定的实用性。关键词：AT89C51，全自动洗衣机，实时控制Based On AT89C51 Automatic Washing MachineABSTRACTWith the rapid development of digital control technology, it is widely used in the field of intelligent control. SCM in terms of volume, full-featured, low cost, the development of convenient advantages in favor of many electronic systems designers, it is suitable for real-time control, may constitute an industrial controller, smart meters, smart interface, smart weapons, devices, and general control unit and so on. In recent years, microcontroller applications continue to go deeper, to promote the detection of the traditional control increasingly update. In real-time detection and automatic control of microcomputer application system, the microcontroller is often used as a core component to be based on the specific hardware architecture design software for the specific application of object characteristics, in order to achieve real-time control.AT89C51 microcontroller as the core design of the control system of the automatic washing machine. This system has control of the washing machine the entire laundry process, including user input parameters, laundry, dehydration and the end of the four stages. The control system mainly consists of three modules of power circuits, digital control circuit and mechanical control circuit composition. Stable 5V DC voltage power supply circuit for the digital control circuit, 220V electricity for the motor; digital control circuit
