 单片机自20世纪70年代问世以来，以其极高的性能价格比，受到人们的重视和关注，应用很广、发展很快。而51系列单片机是各单片机中最为典型和最有代表性的一种。本次设计以AT89S51芯片为核心，辅以必要的外围电路，设计了一个智能自动往返小车，它由5V直流电源供电。在硬件方面，除了CPU外，用来驱动小车运行采用的是H桥电路。通过红外光电传感器对地面状态进行判断并把信号传送到CPU进行相关运算。程序采用C语言编写。整个系统能完成小车的正向和反向运行，并有定时倒车等功能。

Title             Intelligent Car Based on SCM          

                    —— Automatic Round-trip Car         
Abstract
Since 1970s the SCM appeared, because of its extremely high performance-price ratio, it suffered recognition and concern by people. It is widely used and fast development. 51 series SCM is the most typical and most representative of all the SCMs. This design uses AT89S51 as core. With necessary peripheral circuit, design a intelligent automatic round-trip car. It is provide 5V Dc power. In the hardware, in addition to CPU, to drive the car running is H bridge circuit. Through the infrared sensors, it judges ground state and conveys the signal to CPU then conduct calculation. Program uses C language. The whole system can accomplish car forward and reverse operation and has regular backing, and other functions.
