摘要
本设计利用凌阳SPCE061A单片机控制四相步进电机,完成智能小车前轮的连杆传动,带动前轮转向;并通过单片机控制功率放大电路,带动后轮共轴直流电机,完成正转倒转功能;其间的各种行进控制用语音识别来完成,包括前进,后退,停止,左转,右转。在智能车的前端装有两个光线传感器,可以通过对左右光线的变化识别是否将要碰撞前方障碍物,进而反馈到单片机进行转向控制,完成躲避障碍物的功能。
This design uses Sunplus SPCE061A microcontroller to control four-phase stepper motor, complete the rod drive of smart car front wheel, then drive front wheel steering; through microcontroner to control power amplifier circuit, drive rear wheel shaft of the DC motor, complete forward rewind function; the various traveling control are accomplished by voice recognition, including forward, backward, stop, turn left, turn right. In front of the car is equipped with two intelligent light sensor, which can identify whether will collide an obstacle in front through the changes of left and right lights, and then fed back to the microcontroller for steering control, complete the function of avoiding obstacles.
