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 language to write the program, the design of the circuit structure is simple, easy to implement,timeliness is high.
