摘要:

针对空巢老人和卧床病人,设计了基于LabVIEW的睡眠质量实时监测系统。采用光纤布拉格光栅(FBG)作为传感单元,将压力装换为波长漂移,随后通过合理的选取不同峰值波长的20个FBG,使用波分复用技术来构成整个传感网络。使用光纤光栅传感解调仪(Micron Optics SM-125)实现频率为2HZ的数据采集,并将其与计算机连接,数据处理及功能实现采用LabVIEW程序编写。最终实现了睡眠位置、单位时间内翻身次数的睡眠质量实时监测的功能。

Abstract: For empty nesters and bedridden patients, a sleep quality real time monitoring system based on fiber Bragg grating (FBG) is designed and implemented. Using FBG as the sensing elements, the pressure can be converted into the wavelength drift. Wavelength Division Multiplexing (WDM) technique is utilized to form the sensor network on the basis of combining 20 FBGs with different peak wavelength. Fiber grating sensor demodulation instrument (Micron Optics SM-125) is used to achieve a frequency of 2 Hz data collection, and then connected to the computer, data processing and function realization using LabVIEW programming. By using LabVIEW program modules for real-time analysis and computing the experimental data collected, the real time monitoring system of sleep quality with two functions of turnover per unit time and the sleep position has been realized ultimately.
