基于超声波的智能小车设计

Design of Intelligent Car Based on Ultrasonic Wave

随着信息技术的发展,电子控制技术被广泛应用于工农业及生活。本文设计了一款以STC89C52单片机作为主控制器,有测距功能,并能够设置避障距离的红外遥控小车。小车具有lcd1602显示、声光报警、超声波、红外控制等模块,具有避障提醒显示功能,能够显示速度、距离,自动避障,避障灵敏度高,避障范围3~40cm。该系统成本低,功能新颖,可玩性好。

With the development of information technology,electronic control technology is also widely used in industry,agriculture and life.This paper designs an infrared remote control car with STC89C52 single-chip microcomputer as a main control unit,ranging function,and ability to set obstacle avoidance distance.The car has lcd1602 display,sound and light alarm,ultrasonic,infrared control and other modules,has obstacle avoidance remind display function,which can show speed and distance,and automatically avoid obstacle with high obstacle avoidance sensitivity.The obstacle avoidance range is 3-40 cm.The system has low cost,novel function and good playability.
