Microcontroller-based design of intelligent tracking car
ABSTRACT
This topic is based on the STC89C52 single-chip smart car design and implementation.The car finished the main function is to be able to identify independently black guide line and according to the black line to achieve rapid and stable line running.The system 89C51 microcontroller core, using infrared detector on the tube black belt, black belt along the trolley in order to achieve the purpose of tracking the use of ultrasonic testing obstacle avoidance in order to achieve the car's functions.Meanwhile, the car to achieve a PWM automatic speed control function. This paper introduces the infrared black belt tracking and obstacle avoidance system functions is proposed based on the overall system design, analysis of the car-based infrared tracking Black Belt intelligent tracking , obstacle avoidance hardware and software implementation.
