摘要:本系统采用AT89S52作为主控制芯片,利用光电对管的检测,实现小车自动寻路,采用L298N芯片作为直流电机驱动,,实现两车的快慢速行驶和转向。三者的结合使小车更加智能化、自动化;并利用红外避障,实现两车交替超车的功能。整个系统在设计中注意低功耗处理和力求高性价比等细节,电路结构简单,可靠性能高,无论在结构和技术上都具有较好的科学性。
关键词:光电对管,红外避障传感器,LM298电机驱动
Abstract: This system adoption AT89 S52 is a master control chip, make use of red outside vs the examination of tube, carry out a small car to automatically look for road, adopt the L298 N chip as continuous current dynamo to drive bine an optoelectronics in PWM down, carry out the rate of speed of two cars and soon drive and change wedge bonding of threes makes small car more the intelligence turn, bine to make use of red outside avoid Zhang, carry out two cars to alternately overtake a car of whole system notes a low-power transaction and tries hard for details like price ratio higher -,etc in the design, the telephone structure is simple, and the dependable performance is high, regardless all have better science on the structure and the technique.
Keyword: Optoelectronics vs take care of, red outside avoid Zhang to spread feeling machine, LM298 dynamo drive
