摘要社会在进步，科技也在进步，医学也在跟随进步，现在是智能化的世界，人类就医越来越方便，治疗也越来越及时和有效。静脉输液在医学中发挥着越来越大的作用。在现代人类治疗疾病中，这个方式有着举足轻重的地位。这次毕业设计是以研究智能输液报警系统为主旨。本毕业设计是以51单片机为核心。51802

    这个设计非常的简洁方便，而且非常的容易操作，医护人员使用这个设计可以很方便简单的观察到输液的速度，对于医护人员来说具有非常大的意义，使他们的工作变得更加容易，更加轻松，不至于有时会忙的焦头烂额。

本设计可以实现以下功能：可以智能的获得输液时的液滴速度并且在数码管显示，可以设置液滴速度的最高值和最低值，当输液速度不在这个范围内时会报警，并且具有测回血功能，有回血时会报警。填补输液报警系统研究的不足，并且对于医疗的领域的发展具有深刻的影响，促进科研人员的进一步研发。这个设计对于未来此研究提供了重要的支持，同时也会有不俗的成绩。

Design of intelligent monitoring and warning system for transfusion

Abstract  Social progress, science  has made progress, also follow the progress of medical science, the world is more and more intelligent, the human doctor more convenient, but also more timely and effective treatment. Intravenous infusion is playing an increasingly important role in medicine. In the modern treatment of human diseases, this approach has a pivotal position. The graduation project is Intelligent alarm system for the subject transfusion, this graduation design is based on 51 microcontroller core.

  The design is very simple and convenient, but also very easy to operate, health care workers to use this design can easily adjust the infusion rate, have very large implications for health care workers who make their work easier, more relaxed, and will not sometimes so busy.

  This design can realize many functions: intelligent droplet velocity can be obtained during the infusion and digital display, you can set the maximum and minimum values droplet velocity, when the infusion rate is not within this range will call the police and have a blood test back function, it will return to the blood when there is an alarm. Up the shortfall Infusion Alarm System, and has a profound effect on the development of the medical field, and promote further development of researchers. Research this subject for future study provides important support.

  This paper has 15 figures, 3 tables, 15 references.
