摘要
本擦鞋机是采用红外线发射、接收、集成电路控制的新一代电器产品,设计合理、操作简便。伸脚既开,抽脚延时15秒关闭,全自动工作。您要做的就是把脚伸进擦鞋机,其他的事情全部由它来完成。
本设计应用单片机设计一个自动擦鞋机。基于单片机的自动擦鞋机的硬件构成包括变压器、稳压集成模块7805、红外发射与接收管、AT89C51芯片、L293D芯片等组成的电源电路、红外发射与接收电路、单片机系统控制电路、电机驱动电路和显示电路。单片机系统控制电路用来控制整个系统的正常运行,是整个系统的核心。该系统主要通过红外发射与接收电路检测信号,运用单片机的运算和处理能力来实现擦鞋机的转动,并通过显示电路显示其工作状态。

Abstract
The shoe polisher is the use of a new generation of electrical products, integrated circuit, receiving the infrared emission control, reasonable design, easy operation. The foot is open, oil foot 15 second delay shutdown, automatic work. All you have to do is put my foot shoe polisher, other things are done by it.
The design and application of single chip puter to design an automatic shoe machine. Based on single-chip puter automatic shoe machine hardware including voltage transformer, the integrated module 7805, infrared emitting and receiving tube, AT89C51 chip, L293D chip and ponents of the power circuit, infrared emitting and receiving circuit, SCM system control circuit, motor drive circuit and display circuit. The normal operation of the circuit is used to control the whole system controlled by single chip puter system, is the core of the whole system. The system mainly through infrared emitting and receiving circuit testing signals, the use of single-puting and processing power to realize shoe machine rotation, and through the display circuit shows its working state.
Keywords: shoe cleaning machine; automatic coin machine rolling advertisement; single chip puter;
