摘要

本课题设计制作了一款具有语音录放功能的复读机，它具有录音和放音的功能，设

计了电路图，编制了软件并完成安装、调试，形成了样机。作品以两电动机为主驱动，

通过光电三极管来采集信息，送入主控单元 AT89S52 单片机，处理数据后完成相应动作，

以达到自身控制。电机驱动电路采用高电压，高电流，四通道驱动的达林顿管原理的三

极管组合。其中，黑带检测采用红外线接收三极管完成；将信号送单片机处理判别方向。

由控制单元处理数据后完成相应动作，实现了无人控制即可完成一系列动作，相当于简

易机器人。通过本课题的设计，使我们学习了单片机技术的中断技术，更好的掌握了单

片机的核心容。又巩固了模拟电路中的功率放大电路知识，把实践和理论更好的结合。

Abstract

This topic-based group designed manufactures one section to have the

intelligent judgment function car, the car has evades automatically bonds

the function; Seeks the mark (Moving in a certain range) function: May

study the embedded control as the university student the powerful

application example. The work take two electric motors as the focus

actuation, gathers the information through the electro-optical sensing

component, sends in the master control unit AT89S52 monolithic integrated

circuit, after processing the data, completes the corresponding movement,

achieves own control. The motor-driven electric circuit uses the high

voltage, the high electric current, four channels actuate Darington tube.

And, the blanking bar examination uses the photosensitive triode to

complete; Delivers the monolithic integrated circuit processing

distinction direction the signal. Through this topic's design, caused us

to study in the monolithic integrated circuit technology interrupt

technology, better has grasped monolithic integrated circuit's central

content. Causes us the theoretical knowledge which studies to apply in the

practice, caused the practice and the theory obtained a better union.

key words: Monolithic integrated circuit intelligent control

electro-optic signal receiving and dispatching seeks the mark travel
