说明：  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)
