Design of intelligent infrared obstacle avoidance car based on microcontroller

智能红外避障小车利用红外传感器对障碍物和行驶的路况进行判断,从而使小车能顺利地绕过障碍物。文章提出了一种基于STC89C52单片机的智能红外避障小车的设计与实现方法。该设计以两个直流电动机为主动力源进行驱动。电机驱动电路采用了L298N驱动芯片,通过红外传感器来采集信息,并送入主控单片机(STC89C52)进行处理,数据处理完成后执行相应动作,以达到自动控制的目的。本设计中避障模块采用红外线收发来完成,由控制单元处理数据后执行相应动作,实现了无人干预也可完成一系列动作的功能。

That intelligent infrared obstacle avoidance car uses infrared sensors to judge the obstacles and road conditions can make the car be able to smoothly bypass the obstacles.This paper presents a design and implementation method of intelligent infrared obstacle avoidance car based on microcontroller STC89C52.The design uses two DC motors as the main power source to drive.The motor drive circuit uses L298 N driver chip,through the infrared sensor and ultrasonic sensors to collect information,and sent to the master microcontroller（STC89C52） for processing.After data processing,it begins to perform corresponding action to achieve the purpose of automatic control.The obstacle avoidance module in this design is completed with infrared transceiver,after processing data,the control unit perform corresponding action,which achieved the function that completing a series of action without intervention.
