摘要
介绍了一种由AT89C51单片机构成的医院输液监控系统。本系统包括上位机(PC机)和下位机(AT89C51单片机)。本文对系统如何实现自动检测、自动报警等功能做了详细的分析与研究,利用光电传感器采集点滴的有无,用AT89C51作为中央处理器进行信号分析与处理,用RS—485实现上位机(PC机)和下位机(单片机)的通信,用PC机作为上位机对下位机进行控制。
A sort of monitoring system for transfusion in hospital based on AT89C51 is introduced ,which is composed of a PC as host computer and micro-controller AT89C51 as slave. How to realize the auto examination and alarming is analyzed and researched. The system makes use of photoelectric sensor to judge transfusion, AT89C51 to complete the signal analysis and process, RS-485 to implement the communication between PC and single-chip micro-controller, a PC as hoster to control the slave..
