基于体感控制的智能车设计

Design of smart car based on motion sensing control

智能车设计中远程端及控制端采用单片机作为主控制器,远程端即小车端接收到控制端发送过来的控制信号,实现自身转向、姿态变换等动作,姿态传感器安装在人的手背上作为控制端,通过无线装置将相关参数传输到小车上的接收装置,接收器接收到相应参数后,处理器执行相应滤波算法,发送指令,从而实现远程遥控。设计中按照低功耗、高精度原则进行器件选型,主控制器部分、电机驱动等硬件电路设计力求经济性和精简性。软件设计充分发挥软件控制灵活方便的特点,实现了小车的平稳性和精确变换姿态等功能,所实现的智能车可应用于医疗、娱乐等各个领域。

The MCU is taken as the m ain controller of the remote end and control end in the design of smart car. Thecar in the remote end can receive the control signal transmitted from the control end to realize the actions of self-turning and atti-tude transform. The attitude sensor is mounted on the back of the hand as the control end,and transmits the relevant parametersto the receiving device of the car by wireless transmitters. The controller executes the corresponding filtering algorithm after re-ceiving the relevant parameters,and sends instructions to realize remote control. The devices are selected according to the princi-ples of low power consumption and high precision in the design. The hardware circuit design including master controller and mo-tor drive should conform to the requirement of economy and simplification. The software design gives full play to the characteris-tics of the flexible software control to implement the functions of stability and accurate attitude transform of the car. The imple-mented smart car can be applied to the medical treatment,entertainment,and other fields.
