单片机多功能智能小车的设计

北京理工大学珠海学院XXXX届本科生毕业设计intelligentization has become the trend of the world's future development.Intelligentization can operate according to the wishes of human beings,and does notrequire humans to perform too much operations,which greatly reduces the workloadof people.The emergence of smart cars is a big step for human beings to becomeintelligent.Its appearance has greatly accelerated the development of scientificexploration,industrial manufacturing and transportation and other fields.Theprinciple of the smart car contains many subject knowledge,such as sensingtechnology,automatic control principle,remote sensing technology and circuitelectronics.The control core adopted by the designed smart car is STC89C52 singlechip microcomputer,the remote control mode is infrared remote control,and the chipdriven by the motor is L293D.At the same time,the smart car adopts the infrared pairtube as the receiving and transmitting device of the infrared obstacle avoidancemodule and the infrared tracking module,and performs the distance measurement andobstacle avoidance through the HC-SR04 ultrasonic detection module.Theprogramming language used in this design is c language.By inputting the compiledprogram to the single-chip microcomputer,the single-chip microcomputer can controlthe car to realize infrared obstacle avoidance,ultrasonic distance measurementobstacle avoidance,black line tracking and infrared remote control.Keywords:smart car;single chip microcomputer;infrared obstacleavoidance and remote control;ultrasonic;black line tracking
