Design And Implementation Of The Infusion Monitoring System Based On AT89S52

Transfusion commonly used as treatment in hospital, but there were some problems, such as inaccurate, need transfusion of artificial guardianship, etc. The goal is to design a transfusion monitoring system in order to solve those problems.The system use AT89S52 SCM as machine's core. PC through its composition CAN bus cable monitoring system for control of the machine from host. Slave machines through the outer circuit testing reservoir liquid bottle in height and liquid dropping speed, and through the control of stepping motor speed control its infusion.The infusion monitoring system design by this paper, actualize the infusion rate of test, the control of reservoir fluid bottle level detection alarm and dynamic display of transfusion speed. Users can through the button to control transfusion speed and system will automatically transfusion speed of it. Besides the system also actualize multi-machine communication, that is, a master station to control multiple machines from a station and the master-slave data transmission between. When the infusion end or infusion speed abnormal, slave light-emitting diodes and buzzer to alarm, and will alarm signals through serial transmission to the master, stood by monitoring software realization and buzzer sound-light alarm.In the overall program design, in ensuring the use of design systems to achieve the required accuracy and stability of the premise, taking into account the system's portability, practicality, reliability, electrical systems were optimized.Finally, the work of the full text of this article make a summary and outlook, point out future research directions and priorities.
