本设计分为四个模块,分别是电机驱动模块,超声波传感器模块,单片机模块和液晶显示模块。单片机和电机驱动用于控制风力的大小和稳定性。超声波模块利用超声波传感器对简易风洞内乒乓球的位置进行判断。在简易风洞上端利用传感器和液晶显示配合是本设计的一个亮点,乒乓球在运动过程中液晶屏幕可显示乒乓球的运动高度。
The design is divided into four modules, namely motor drive module, ultrasonic sensor module, microcontroller module and LCD module. Microcontroller and motor drives are used to control the size and stability of the wind. The ultrasonic module uses the ultrasonic sensor to judge the position of table tennis in the simple wind tunnel. In the simple top of the wind tunnel using sensors and LCD display is a bright spot in this design, table tennis during the LCD screen can display the movement of table tennis height.
