摘 要
本设计以家用全自动洗衣机的工作过程为研究模型，以意法半导体公司的单片机STM32F103CBT6为控制核心，完成了电源供电电路、液晶接口电路、直流电机驱动电路、继电器控制电路、按键扫描电路、AD信号采集电路、蜂鸣器报警电路、童锁认证电路的设计，实现了对洗衣机的洗涤、漂洗、甩干工作状态的智能控制。其中童锁认证功能是为解决儿童使用安全问题而特别设计的。软件部分的设计包括：洗衣代码选择、洗衣倒计时显示、进水指示、排水指示、电机旋转、童锁认证等主要过程控制及显示。通过Keil软件编程来控制电机旋转、12864液晶显示等主要动作。其中液晶菜单界面的显示设计是关键环节，采用12864液晶的图形显示功能，通过不同的反白及非反白图片之间的切换，设计了良好的人机交互界面。设置有一级、二级菜单选项，用户可以按提示操作相应的按键，安全、放心地完成自己设定的洗衣过程。

Abstract
The design of the work process for the study of household automatic washing machine model to STMicroelectronics microcontroller STM32F103CBT6 as the control center , the completion of the power supply circuit , LCD interface circuit , DC motor drive circuit , relay control circuit , key scan circuit , AD signal acquisition circuit, buzzer alarm circuit , circuit design certified child lock , realized on the washing machine washing , rinsing, drying intelligent control working conditions. Certified child lock function which is to solve the security problems of children using specially designed . Software part of the design include : laundry code selection , laundry countdown show , indicating water , drainage directions , motor rotation , child lock certification and other major process control and display. By Keil software programming to control the motor rotation, 12864 LCD and other major actions. LCD which displays the menu interface design is the key , using 12864 LCD graphics display capabilities, by switching different highlight and non- highlight between pictures , design a good man-machine interface . Provided with primary, secondary menu option, the user can press the corresponding button prompts , security , ease to complete their own set of laundry process .
