电动车跷跷板的设计
首发时间:2009-06-15
摘要:本系统采用两个直流减速电机分别控制小车的两个后轮,用一个舵机控制共轴的前轮;用反射式红外光电发射—接收器识别跷跷板上的引导线;用固体摆式倾角传感器测量跷跷板倾角。以LPC2142为控制核心,对寻迹模块和角度测量模块的输出信号进行处理。通过PID算法,利用PWM技术动态控制直流减速电机的转速和舵机的转角,使电动小车平稳地在跷跷板上行驶,在有无配重两种情况下自行寻找平衡点,并通过LCD分阶段显示系统运动的相关信息。

The Design of the Electric Car Running on the Teeterboard
Abstract:This system uses two DC motors to control the two rear wheels of the cars, with a steering gear controling the front wheel; It uses reflective infrared light electric launch - receiver to identify the guide lines of the electric car and use solid tilting angle sensor to measure the angle of the teeterboard.With LPC2142 as the dominate core, deal with the output signal of the tracing angle module and measurement module. Using the PID algorithm, DC motor speed reducer and gear corners can be dynamicly controlled by the use of PWM technology, so that a electric car will travel in the seesaw smoothly, achieving the equilibrium point whether with weight or not, then can display movement-related information systems through the phased LCD.
