摘要
系统由重力感应遥控板和被控小车两部分构成。遥控板部分通过MMA7361加速度传感器感知遥控板的倾斜方向和倾斜角度,通过ATmega8单片机内置A/D转换器获取传感器采集到的信息,经编码后,通过无线串口发送出去;被控小车通过无线接收模块接收到遥控板发送来的编码信息,由ATmega8单片机完成相应的解码工作,获取遥控板发出的控制信息,通过电机驱动模块对小车左右电机进行驱动,从而完成相应动作。经实际制作和检验,小车运动姿态与遥控板控制姿态高度协调,反应灵敏,满足设计要求。
The system is composed of a gravity sensing remote board and a remote control car. The acceleration sensor MMA7361 is used to sense the tilt direction and tilt angle of the remote control board. The information collected by the sensor are converted by the A/D converter built in ATmega8 microcontroller and sent out through the wireless serial port after coding. The controlled car receives the information through the wireless receiver module, decodes the corresponding information by ATmega8 microcontroller, then gets the remote control information from the board and drives the car through the driven motor module, thereby completes the required movements. It is testified that the movement posture of the car are highly coordinated with that of remote control board . With the sensitive reaction, the car performs successfully in an all-round way to meet the design requirements.
