| 摘 要： | TX-2B编码的控制按键基带信号经ASK振幅键控后由30 MHz的载波发射,通过超再生接收电路再由RX-2B解码后,无线信号转化为数字脉冲信号并输入到AT89C51。从而控制单片机输出PWM信号,控制功率管驱动电路,配合直流电动机及现有玩具小车机械传动装置,实现遥控电动玩具车的前进、后退、加速、左右转等功能。

| Abstract: | The base-band signal,coded by TX-2B as the control key,is transmitted on 30 MHz carrier wave after being modulated with ASK.The wireless signal,after being decoded with RX-2B is transformed into digital signal and then sent to AT89C51 as the control signal.The PWM output from AT89C51 control the power driver of the DC motor,so the mini car,as the load of DC motor,can fulfill the functions such as forward or backward,left or right,even accelerate. |
