毕业设计(论文)
摘要
自从首个工业智能设施诞生以来，智能设施的发展已经扩展到了包括机器、刻板、电子、冶金、交通、宇航迅速上升，大大的改变了大多数人类的生活方式。在人类的智能化技术不断飞速进步的过程中，能够取代手动的机器人在更加人性化的同时也越来越智能化。
本文主要讨论了基于单片机的智能循迹避障小车的设计。智能自动循迹制导系统在驱动电路的基础上，实现自动跟踪汽车导线，而智能避障是使用红外传感器测距系统来实现功能来规避障碍。智能寻光避障小车是一种采用了多种传感器，以单片机为核心，电力马达驱动和自动控制为技术，根据程序预先确定的模式，而不是人工管理来实现避障导航的自动跟踪高新技术。这项技术已广泛应用于智能无人驾驶、智能机器人、全自动工厂等许多领域。
这个设计使用STC89C52单片机[1]作为小车的智能核心，使用红外传感器对智能小车跟踪模块识别引导线跟踪，收集模拟信号并将信号转换成为数字信号，使用C语言编写程序，设计的电路结构简单，易于实现，时效性高。

ABSTRACT
From the first level of industrial intelligent facilities since birth, the development of intelligent facilities has been broadened to include machinery, electronics, metallurgy, transportation, aerospace, defense and other fields. Intelligent facilities level rising in recent years, and rapidly, significantly changed the way people live. People in the process of thinking, improvement, learning and intelligence of replace the manual machine is more and more.
This paper mainly discusses the intelligent tracking based on single chip microcomputer control process of the obstacle avoidance car. Intelligent automatic tracking is based on the driving circuit of the guidance system, to achieve automatic tracking car line; obstacle avoidance is the use of infrared sensor ranging system to realize the function to evade obstacles. Intelligent tracking obstacle avoidance car is a use different sensor , motor drive for power and automatic control technology to realize according to the procedures predetermined mode, not by artificial management can realize the automatic tracking of obstacle avoidance navigation of high and new technology. The technology has been widely used in unmanned intelligent unmanned line, intelligent robot and so on many fields.
Using infrared sensors for car tracking module to identify the guide line tracking, collecting analog signal and converts the signal into digital signal; Using C
