摘要
随着我国智能行业的飞速发展,解放人类劳动力的理念不断普及,智能跟随小车出现在人们视野里,它可以解放人们双手,提高物品搬运的效率,减轻人们的负担同时为其他工作节约时间。基于此,该文设计了一款基于红外技术和超声波测距的智能跟随小车。小车以AT89C52芯片为核心控制器,3个人体红外传感器HC-SR501用于识别人所在的位置,把识别到的信号通过核心控制器传送给L298N电机驱动模块,从而实现对小车转向和行驶的控制;超声波传感器HC-SR04用于检测人与小车之间的距离,当距离小于0.5 m时,实现小车报警同时后退,保证人与小车之间的安全距离,防止发生碰撞。样机测试结果显示,小车能在4 m以内对人自动跟随,并与人保持0.5 m的安全距离,防止碰撞,具有一定的实用价值。
With the rapid development of the intelligent industry in China,the concept of liberating human labor force continues to be popularized,and the intelligent following car appears in people's vision.It can free people's hands,improve the efficiency of goods handling,reduce the burden and save time for other work.Based on this,this paper designs an intelligent following car based on infrared technology and ultrasonic ranging.The car uses the AT89C52 chip as its core controller,uses three pyroelectric infrared sensors HC-SR501 to identify the position of the person,and transmits the identified signal to the L298N motor drive module through the core controller,so as to realize the control of the car's steering and driving.It uses the ultrasonic sensor HC-SR04 to detect the distance between people and cars,and the car gives and alarm and retreats at the same time when the distance is less than 0.5m,so as to ensure the safe distance between people and cars and prevent collision,which has certain practical value.
