A Transfusion Monitor Based on Fuzzy Neural Network
Hen P · Microcomputer Information · 2007
The monitor combines the transfusion sensor, the electric apparatus, the LCD screen, the keyboard and the MSP430 MCU as the core of control 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 arti- cle introduced a control method based on fuzzy neural network, which integrates the excellences of fuzzy logical control and neural network. The method uses neural network to remember fuzzy rule and achieve fuzzy control and uses error back propagation to realize online self- learning when the control object parameter has changed. So it can colligate, analysis and dispose data quickly and exactly to achieve intelligent control. Through examination, this monitor manages accurately, runs credibility, and its small bulk, low cost and convenient manipulation makes it worth popularizing and applying.
