Abstract
With the development at full speed of science and technology in recent years, the application of the one-chip computer is being moved towards deepening constantly. Liquid dropping speed monitoring system based on SCM is an automated system which can take the place of the medical staff to monitor the patients' dropping speed. The system presents a design method of the speed monitoring device which can control and monitor the dropping speed and display the current speed through the display device. When the liquid medicine is below a certain standard, the buzzer can be used to give an alarm. The system uses AT89C52 as the core processing unit. The photosensitive sensor is used to test the numbers of the liquid drop. With the use of stepping motor, the control clip position is adjusted to control the speed.
Through comparison, this system is proved to be simple to operate. It has software simulation design and is more scientific. The theory can be used in the medical practice.
Intelligent medical infusion monitoring system designed in this paper has the advantages of easy to use and a high ratio of performance to price which basically meets the requirements of hospitals.This system not only ensures the safety and stability of infusion process, reduces the burden of nurses, but also makes infusion network automated and intelligent, which has a wide range of application prospects.

Key words：AT89C52 single-chip microcomputer; photoelectric sensors; liquid drip monitoring；buzzer
