嵌入式睡眠监测系统的设计与实现

摘要

Embedded sleep-monitoring system is designed to sample sleepers' pulse signals without disturbing their sleeping process, and the pulse signals will be transmitted to personal computer via wireless network, displayed and analyzed on virtual instruments platform which is built by LabVIEW. At the same time, the face images of the sleepers will be collected by camera of the PC and stored the image information which synchronizes with the pulse signals. The result of the experiments indicate that embedded sleep-monitoring system has a good real-time performance and high reliability for monitoring the sleeping process. It provide important reference for assessing the quality of sleeping.%设计了嵌入式睡眠监测系统,在不干扰睡眠的前提下,对睡眠者的脉搏信号进行采样,通过无线网络传输至上位机,利用LabVIEW搭建上位机虚拟仪器平台,实现脉搏信号的实时显示与分析;同时,利用上位机摄像头采集睡眠者睡眠过程的面部图像,存储与脉搏信号同步的图像信息,可提高对脉搏信号分析的可靠性；测试实验对比分析了睡眠期间分别使用该系统与传统方式所测得的心率参数,结果表明嵌入式睡眠监测系统对睡眠过程进行监测的实时性好、可靠性高,对睡眠质量的评估提供重要的参考依据.
