摘要
以MSP430单片机为控制核心,结合输液传感器、电动执行器、液晶显示、键盘等组成智能输液监控系统,实现了输液过程的自动监控.信号传感方式采用了红外光电传感器,通过滤波消除杂散光干扰.原始信号的处理采用了锁相环倍频技术从而提高了采样速度并缩短系统调整时间.通过下位机与上位机之间的串行通信,系统还实现对多台下位机进行远程监控与管理.
With the MSP430 singlecbip as the core of control, this system combined transfusion sensor, electric apparatus, LCD screen and keyboard to realize automatic monitor for transfusion process. Infrared photoelectric sensing is adopted for signal sensing, astigmia interference is eliminated by filtering. And the initial signal processing is done by frequency doubling of PLL for a higher speed of processing and adjusting. Using serial communication between singlechip and computer the system realize long-distance monitor and manage to many singlechip.
