Washing Machine’s Intelligent Control System based on Single-Chip Microcomputer AT89C52 SCM

本文采用AT89C52单片机对洗衣机进行智能控制．通过74LS138译码器，水位检测机构、LED数码显示器．键盘等硬件设计实现了洗衣机工作过程的自动化。应用表明该系统具有洗涤（强洗、弱洗）、脱水，定时以及洗涤次数和动作编程等功能，从而极大地提高效率．降低功耗，减少噪声。

This paper is based on single-chip microcomputer, which carries on washing machine＇s intelligent control. AT89C52 single-chip microcomputer is used to control a washing machine, carried by 74LS138 decoder, detector of water level. LED numeral display, keyboard and so on to realize the automation of washing machine＇s work. The application indicates that the system functions include washing （strong washing and soft washing）, dehydration, fixed time. times of washing and motion programming. Therefore, the machine can enhance its efficiency, lower energy consumption and reduce noise.
