Intelligent Medical Monitoring System Based on Laser Sensing Communication Technology

Laser sensing communication technology is applied in the field of intelligent medical monitoring,and an intelligent medical monitoring system with high monitoring accuracy and high transmission rate is designed. Temperature measurement module is designed by using laser sensing technology. The module adopts F-P cavity matched filter demodulation method. Pumping source emits broad-band light to generate laser in the resonator. After reaching the grating,the original reflection reaches the center wavelength of the F-P cavity to demodulate. Photodetector receives the convolution of grating reflection light and F-P cavity transmission light to obtain temperature monitoring. Measuring signal;Laser frequency hopping communication module FPGA transmits and receives medical data through serial port.The ASK baseband coded laser modulation module calculates variable baseband frequency modulation signal based on the principle that modulation laser cycle frequency changes with modulation signal baseband frequency to realize medical data communication transmission. The following experimental conclusions are obtained: the temperature measurement module can improve the central wavelength and save the time of measuring human body temperature;the laser communication module can transmit medical data continuously and run steadily.
