基于单片机的智能避障小车系统设计

摘要

介绍了一种基于AT89S52单片机的智能避障小车。系统以AT89S52为控制核心，采用3组红外传感器完成障碍物检测。通过I/O口控制360°伺服舵机实现小车前进、倒退、转向、避障等动作，利用PWM(脉宽调制)方法可精确控制小车运行速度。系统电路结构简单，响应速度快，实践证明小车能够成功实现自动避障。%This paper introduces an intel igent obstacle avoidance car based on SCMC.The system uses AT89S52 as the control core,using 3 groups of infrared sensors for obstacle detection.Through the I/O port control 360 °servo realize the car’s forward,backwards,steering,obstacle avoidance action ect,and using the Pulse-Width Modulation(PWM)method can control the speed of the car accuracy.This system has the advantages of simple structure,fast response speed and test proved that the car could keep away from the obstacle successful y.
