摘要
随着杰出科技人才的涌现,现代化科技蓬勃发展。近年来,单片机的使用范围一步步的不断扩展。基于单片机的输液滴速控制系统是一个可以取代医护人员监测和控制患者输液滴速的自动化系统。这个系统给出了一种输液滴速控制装置的实现办法，能够使系统控制输液滴速并经过数码管显示当前速度，当药液低于警戒线时可通过蜂鸣器报警。系统使用AT89C52作为核心处理单元，光敏传感器检测输液管里液体的滴速，夹持器通过步进电机进行调整挤压或者松开来控制输液滴速，通过多种方案对照比较得出，该系统使用简单明了，并且进行了软件proteus仿真设计，理论联系实际，更具科学性。
本文通过对医院输液检测系统的具体研究，设计出了使用简单，性价比高的输液滴速控制装置，基本上满足了医院的实际应用。本次设计可以确保输液过程的稳定性和安全性，实现了医院输液的智能化和自动化，帮医护人员担负起了部分工作，应用前景非常广阔。

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
