嵌入式睡眠监测分析系统研究与设计

摘要

设计一种睡眠监测分析系统,在不影响自然睡眠的情况下采集、存储人体几种生理信号.利用虚拟仪器(LabVIEW)技术在PC机上搭建信号分析处理平台.对存储信号采用时域、频域及功率谱等方法进行分析研究,挖掘蕴涵在信号中与睡眠相关的生理病理信息;对受检者进行呼吸率、心率检测试验,结果表明该监测分析系统与PSG方法检测结果基本相符;嵌入式睡眠监测分析系统方便、实用且监测费用低,可以为医生诊断提供比较准确的病理依据,在医院临床和家庭监护方面具有应用推广价值.%A sleep-monitoring analysis system was designed to collect and store people' s several kinds of physiology signal without affecting their sleep. A signal analytical processing platform was set up on personal computer through virtual instrument technique, in order to analyze the stored signal by the methods such as time domain method, frequency domain method and power spectrum and so on, then extract the physiological and pathological information related with sleep from these signals. According to the experimental study on respiration rate and heart rate for the patients, the results indicated that the result of this monitoring and analysing system is in accordance with the results of PSG detection. Embedded sleeping monitoring and analysing system is not only convenient and practical, but also low cost. At the same time, precise pathological evidence is provided for the doctors. In a word, It has great value to be applied in the hospital or household healthcare fields.
