摘要
本设计的目的是使电动小车在跷跷板上按预定轨道运行,并能够在过中点后自动寻找平衡。为使电动车在跷跷板上按要求准确运行采用了单片机AT89C51最小系统作为电动车的检测和控制系统。通过红外发射接收一体探头检测路面黑色寻迹线,使小车按预定轨道行驶,根据角度传感器检测跷跷板的平衡状态,控制电动车使其在跷跷板上达到动态平衡。再加上基于AT89C51单片机的键盘、液晶显示电路,构成了整个系统的硬件总电路。最后通过软件设计,实现了按预定轨道行驶、保持平衡等功能。本设计通过实际检测获得圆满成功。
In order to let the electromotion dolly run on the teeterboard exactly,our design adopts SCM-AT89C51 least system as dollys measure and control system. Through examining the black trace by infrared ray electopult-receiver, to make the dolly run on the prearrange orbit, the other, bases on angle transducer, SCM examines the balance state of the teeterboard to control the electromotion dolly reach to balance on the teeterboard. We also introduced the keyboard based on AT89C51 SCM and fluiding crystal revealing electrocircuit, which constituents the chief hardware electrocircuit of the entire system. Finally, the function is realized including run on the orbit, keep balance, etc, using software designment.
