全自动洗衣机的控制系统。设计以单片机AT89C51为核心控制部件，通过水位检测机构、电机控制部分、数码管显示器、按键、蜂鸣器等硬件设计实现了洗衣机工作过程的自动化。首先提出了总体设计方案，接着简要介绍了AT89C51芯片和数码管驱动芯片74LS244等器件的功能和使用方法，然后对系统各模块电路的工作原理进行了详细的分析，从而设计并给出了各驱动电路和芯片控制电路的硬件接口电路图，画出了各驱动电路的流程图，同时在Keil-UV3的环境下编写了各电路的驱动程序和控制程序，实现了系统的输入和输出控制，从而使洗衣机的工作方式自动化-Automatic washing machine control system. Design AT89C51 microcontroller as the core control unit, through water level detection mechanism, motor control section, digital display, keypad, buzzer, etc. hardware design to achieve a washing machine automation of work processes. First proposed the overall design scheme, followed by a brief introduction AT89C51 chip and LED Driver IC 74LS244 devices such as the function and use, and then each module circuit works carried out a detailed analysis in order to design and gives the driver circuit and control circuit chip hardware interface circuit, draw a flow chart of the driving circuit, while Keil-UV3 environment prepared each circuit drivers and control procedures to achieve the system' s input and output control, so that the Automated washing machine works
