迷宫小车系统设计
摘要：设计了一个基于单片机控制的迷宫小车系统。该系统采用AT89S52单片机为主控制核心，实现信号采集，路线判断，行驶总时间的显示，以控制小车的运动；利用光电开关感应墙体的存在，结合L298N芯片驱动减速电机运转，从而实现小车走迷宫。
该系统有单片机控制模块和光电监测模块两个主要功能模块。单片机控制模块主要利用单片机接受到光电开关输出的高低电平后再输出信号去控制小车的运动；光电监测模块则利用光电传感器对墙体的感应，然后输出相应的高低电平并传送给单片机。这样就可以实时监测小车在迷宫中所处的位置，并进行相应的运动，最终经判断让小车停止在迷宫出口指定的位置上。

Abstract：Microcontroller AT89S52 is used to this maze trolley system to achieve signal acquisition ,line judge and the display of the driving total time.The principle of this system is that use photoelectric sensors which senses the presence of wall combined with the L298N chip to drive the DC Motor，achieve the purpose of making the trolley move and locate, Then achieve the goal that trolley move in the maze!
This system composed of modules such as SCM Control Module，Photoelectricity Monitoring Module,and so on.The SCM Control Module uses the SCM to output singnal after receiving the high-low output of photoelectric switches in order to control the move of trolley. Then the Photoelectricity Monitoring Module uses photoelectric sensors to judge the presence of wall ,then output corresponding high-low voltage to transmit to the microcontroller .This allows real-time monitoring of car position in the maze, and the corresponding movement,at last achieve the goal of making the trolley stop at the specified location.
