Design and realization of a multi-purpose intelligentinfusion controller

We introduce a new infusion control device.The device use infrared sensors to collect the liquid flow velocity information.A single chip microcomputer AT89C51 as the main control chip calculates and handles the collected data,keyboard inputs information,control step motor infusion dripping speed and makes proper adjustment,eventually adjustes the result and displays that on the lcd1602.Moreover the device can realize the artificial forced alarm at infusion processes and it has automatic alarm function at the end of the infusion.This device can solve the problem of infusion speed measurement and the inconvenience control in the way of artificial infusion.And the characteristics are easily operation and the fast response speed.
