A Transfusion Monitor According to Fuzzy Neural Network

摘要

With the MSP430 MCU as the core of control, the monitor combines the transfusion sensor, the electric apparatus, the LCDscreen and the keyboard to realize automatic monitor for transfusion process. Because transfusion system is nonlinear and complex,which changes now and then and lags behind hour, conventional control method can hardly obtain benign real time monitor effect.This article introduced a control method according to fuzzy neural network, which integrates the excellences of fuzzy logical controland neural network. The method uses neural network to remember fuzzy rule and achieve fuzzy control and uses error back propaga-tion to realize online self- learning when the control object parameter has changed. So it can colligate, analysis and dispose dataquickly and exactly to achieve intelligent control. Through examination, this monitor manages accurately, runs credibility, and itssmall bulk, low cost and convenient manipulation makes it worth popularizing and applying.
