Answer 1

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.
