本次设计的简易智能寻迹小车(寻迹是指小车在白色地板上循黑线行走.通常采取的方法是红外探测法),采用AT89S52单片机为检测控制核心.使用3个高灵敏度的红外反射式光电传感器,对路面的黑色轨迹进行检测.利用小车前面的红外线传感器检测道路上的轨迹,将路面信息转送给AT89S52,AT89S52根据信息做出反应控制电动机转动,从而控制小车按照路上的轨迹行驶.另外,智能车控制系统不同电路模块需要的工作电压和电流容量各不相同.芯片需要提供5V的工作电压,而电机所需的电压为9V,本设计中用到的是9V的电源供电,通过三端稳压器LM7805将电压变换为5V电压供给电路系统.因此,本系统由红外光电传感器,单片机和驱动单元共同作用,由三端稳压器LM7805转换成模块所需电压,保证小车能在预先设定的轨迹上行驶.整个系统的电路结构简单,可靠性能高并且较容易实现,具有高度的智能化、人性化,一定程度体现了智能.实验测试结果满足要求,本文着重介绍了该系统的硬件设计方法及测试结果分析.
小车采用的技术主要有传感器的有效应用和AT89S52芯片的使用.有很多功能可以继续扩展,值得进一步学习和研究.

The design of simple intelligent tracing the car (tracing is to point to the small car in the white floor walk. Usually take to follow the black line is the method of infrared detection method), used for testing AT89S52 SCM control core. Use of three high sensitivity of infrared reflecting photoelectric sensor, the black road to track detection. Use the car in front of the infrared sensor test track on the road, road surface message to AT89S52 devices, AT89S52 devices according to the information reaction control motor rotation, so as to control the car on the way of running according to track. In addition, intelligent vehicle control system of the circuit module need different working voltage and current capacity each are not identical. Chip need to provide 5 V working voltage, and the voltage motor for 9 V, this design is used in 9 V power supply, through the LM7805 voltage stabilizer three will voltage transform for 5 V voltage supply circuit system. Therefore, the system is composed of electrcal sensor, microcontroller and drive units joint action by the three LM7805 convert module regulators required voltage, keep the small car in the predefined driving on the track. The whole system of the circuit structure is simple, reliable performance and is easy to realize high, are highly intelligent, and human nature, partly reflects the intelligence. The test results meet the requirements, the paper introduces the system hardware design methods and test results.
The adopted technology of the car main sensor effective application and the use of AT89S52 chip. Have many functions can continue to expand, deserves further study and research.
