摘要
设计构建了一个以PC机为上位机、以单片机为下位机、以RS485总线为基础的网络输液监控系统。在上位机中采用VC++可视化语言编程,创建可监视输液速度、设定速度、报警等多项功能的人机界面;下位机以8051单片机为核心,具有RS485总线转换接口、液滴检测、液滴速度控制、体温检测、脉搏检测、多种报警以及数据显示功能的监控终端系统。
A transfusion-surveillance-control system which uses RS485 bus network and employs personal computer as an upper computer and microcontroller as terminals is designed. In the upper computer, the VC ＋＋ visual program is used to process data and control transfusion speed, and an interface of person-to-computer is created through which a nurse can monitor transfusion speed, target speed, the rest liquid, body temperature, pulse and alarm etc. In the terminal, transfusion-surveillance-control system is designed, which has RS485 bus transfer interface, liquid drop infrared test, liquid speed control, body temperature test, pulse test and multiple alarm etc, in addition monitor data.
