本系统采用AT89S52为控制CPU,实现玩具小车的智能控制.整个智能小车智能控制模块包括：前轮PWM驱动电路、后轮PWM驱动电路、轨迹探测模块、障碍物探测模块、金属探测模块、速度测量模块、数码管显示模块等.前轮和后轮驱动电路是采用BA6219控制芯片控制小车的运行.轨迹探测模块才用反射式红外接收头能够对黑线轨迹进行检测,障碍物探测模块采用红外接近开关对障碍物进行测量,金属探测模块采用电感式接近开关检测金属模块,速度测量模块采用对射式光电开关对小车的速度进行实时测量,显示模块主要对小车读运行速度和行程等参数进行显示.单片机对各个信号进行分析和处理对小车进行实时控制使小车能够跟踪黑线通过障碍物,并跟踪黑线路返回到起始位置.

This system uses AT89S52 controls CPU,realizes the toy carintelligent control.The entire intelligent car intelligence controlmodule includes:Front wheel PWM actuation electric circuit,trailingwheel PWM actuation electric circuit,path survey module,obstaclesurvey module,metal survey module,velocity measurement module,digital tube demonstration module and so on.The front wheel and therear wheel drive electric circuit is uses the BA6219 control chip tocontrol the car the movement.The path survey module only then usesthe reflection type infrared to meet can carry on theexamination to the heavy line path,the obstacle survey module usesinfrared approaches the switch to carry on the survey to the obstacle,the metal survey module uses the inductance type to approach theswitch examination metal module,the velocity measurement module usesthe correlation type photoelectricity switch to carry on the real-timemeasurement to the car speed,demonstrated the module mainly readsparameter and so on running rate and travelling schedule to the carcarries on the demonstration.The monolithic integrated circuitcarries on to each signal analyzes and processes to the car carries onthe real-time control to enable the car to track the heavy line thepassing obstacles,and tracks the black line to return to thereference.
