声音导引系统(B 题)
摘要:
本设计采用两片凌阳 16 位单片机 SPCE061A 构成主从机系统。主机作为系统的中央控制
单元,实现声源的检测和数据的处理;从机接收主机的命令,控制载有声源的小车由起始位
置到达指定位置,并保持定位精度小于 1cm。Mic 作为声音信号接收器,ASSP 芯片实现可移
动声源的运动控制,L298 芯片驱动直流电机,信号接收器接收声音的时间差决定小车的行进
方向及行进速度。该系统还具有到达指定目标后语音提示的功能。

Abstract:
This design uses two 16-bit MCU SPCE061A to make up Master-slave computer system.
The host as a system of central control unit, to achieve sound source detection and
data processing; the slave machine receives the command and controls the car with
the sound source from the start position to the specified location, and to maintain
positioning accuracy of less than 1cm. Mic acts as a sound signal receiver, ASSP
controls movement of the car, L298 DC motor driver chip. According to the time
difference of the sound ,the signal receivers change the direction and speed of the
car. The system also has voice prompts when reaching the target.
