智能输液检测程序。使用接近开关检测输液瓶中的液滴数，通过定时程序，可以计算出液滴速度。通过计算液滴数量，实现输液体积的换算，通过LCD显示。并使用串口与上位机通讯，发送液滴速度与液体体积数据。-The smart infusion testing procedures. Use close to the number of switches detect the droplets of the infusion bottle, through the regular procedures, the droplet velocity can be calculated. By calculating the droplet number, and the infusion volume of conversion, through the LCD display. And use the serial communication with the host computer to send the droplet velocity and liquid volume data.
