基于C51单片机的智能循迹小车设计与实现

介绍了一种基于C51单片机的智能循迹小车。设计了以AT89S52单片机为核心，通过QTI红外传感器检测路面黑线的控制系统。单片机根据传感器信号控制360°伺服舵机，实现小车左右轮的速度和方向的控制。系统电路结构简单。实际测试证明，该系统控制下的小车具有很好的识别能力，为轮式机器人的设计制作提供了参考。

The Design and Implementation of the Intelligent Tracking Car Based on Single-chip Microcomputer C51

This paper introduces an intelligent tracking car based on MCU C51. The control system is designed using AT89S52 as controller,and using quick track infrared（QTI） infrared sensor to detects the black line . According to the sensor signal, 360° servo steering gears are controlled by MCU to achieve control of the car speed and direction of the left and fight wheels. The circuit of the system is simple and actual test proved that the ear that under the control of this system has a good ability to identify, and provide a reference for the design and implementation of the wheeled robot.
