STC89C52 microcontroller-based intelligent car obstacle
avoidance Design
Abstract
This paper describes the design and implementation of the smart car obstacle
avoidance STC89C52 microcontroller based. Trolley primarily through MCU
control of their own to be able to identify the black line and detect obstacles and
achieve traveling in a fixed track and has an automatic obstacle avoidance
function. The design for the smallest single-chip systems, motor drives, infrared
obstacle avoidance were given the corresponding hardware circuit design. Based
on the principles of PCB design, anti-jamming measures, to design a printed
circuit board. The design uses STC89C52 microcontroller for the control system,
L298N as motor drive, four infrared detection system as obstacle avoidance
system microcontroller PWM wave generated by L298N to the direction and
speed of the car can be controlled. Experimental test results meet the basic
requirements.
