Abstract

With the continuous development of modernization and

automation increasingly popular, the application of sensor, demanding more and more get high, the precision mechanical automation development, design oriented adopted as control

core and AT89S52 SCM by infrared sensor detects the pipe

to follow black with ultrasonic ranging tracing purpose,

the principle of automatic control electric cars and to

detect obstacles obstacle avoidance, the color of speed, speed, and automatic parking, automatic tracing, overall system circuit structure is simple, reliable performance

is high. This design is according to guangxi university students electronic design competition first stage three

senior undergraduate group of topic, the topic request as

table 1.

Using technology mainly include:

（1）AT89S52 Microcomputer application;

（2）L298 motor drive and PWN; motor speed

（3）Sensor effective application; （4）Program use of the algorithm.
