基于STC12C5A60S2的智能循迹小车设计

Design of Intelligent Tracking Car Based on STC12C5A60S2

本设计采用STC12C5A60S2单片机为简易智能小车的核心器件。循迹模块由3对红外收发管组成,通过反射红外线的变化判断黑线的有无以达到循迹的功能,电机驱动模块选用H桥驱动芯片L293D结合单片机来控制电机工作。整个系统的电路结构简单,可靠性能高,能满足设计的要求。

The design adopts STC12C5A60S2 mierocontroller as the core device of simple smart car. The tracking module is composed of a plurality of photoelectric tube, by reflecting infrared changes in judgments of black have to achieve the tracking function, motor drive module selection of commonly used H bridge driver L293D with single-chip microcomputer to control the motor working. The electric circuit construction of whole system is simple, reliable performance. It can meet a,variety of design requirements.
