摘要
设计了一种以红外传感器ST188、AT89S51为控制核心的自动循迹小车,系统采用单片机AT89S51产生PWM波调控小车速度,红外传感器ST188对路面黑色轨迹进行检测,并将检测到的信号反馈给微控系统AT89S51,AT89S51由采集到的信号发出指令,控制小车电机驱动电路以调整行驶方向,从而使小车能够沿着黑色轨迹自动行驶,实现小车自动循迹的目的。
A kind of automatic tracing car based on infrared sensor ST188 and microcomputer AT89S51 as the control core is designed. The system adopts the single chip AT89S51 generated PWM wave control of speed of a car, infrared sensor on the ST188 pavement black locus is detected, and the detected signal is fed back to the micro control system AT89S51, AT89S51 from the collected signal issues an instruction to control motor drive circuit of the car to adjust the driving direction so that the car can run along the black path and realizes the purpose of tracking automatically for the car.
