【摘要】：现代生活节奏加快,竞争压力日益增大,越来越多的人睡眠受到影响,迫切需要研究新方法和新技术以评估睡眠质量好坏,辅以科学地指导,这样对改善睡眠质量会有很大的帮助。目前评价睡眠质量应用的较多的是利用多导睡眠图机监测脑电图、心电图、肌电图、血氧饱和度等10余个通道的生理信号,通过对这些信号的分析来评估睡眠质量;此外,通过睡眠质量指数量表检测也是睡眠评估的重要方法之一。本论文研究基于Android系统的睡眠质量评估系统,该系统实现了血氧饱和度信号的硬件采集模块、手机端信号分析算法模块及通信模块,同时也在手机端植入了睡眠质量指数量表辅助评价。血氧饱和度信号硬件采集模块的实现。通过自己搭建模拟前端电路,包括探头驱动电路、前置放大电路、同反相放大及信号分离电路、自动呢增益控制电路、低通电路等通过时序控制红光及红外光的发射。大量实验表明这两种波长的透射光强的比值,与脉搏血氧饱和度(SpO2)的值近似成线性,利用这一特性将检测到的透射光强的比值转换成我们需要的血氧饱和度的值。Android手机端信号的接收及信号分析算法的实现。在血氧参数采集模块端增加蓝牙传输模块,将检测端采集到的脉搏血氧饱和度等生理数据发送至Android系统智能手机端,智能手机端利用Android蓝牙API开发类,对手机端蓝牙实现打开蓝牙、搜索附近蓝牙设备等基本操作,实现数据传输,并在手机端显示接收到的生理信息。然后根据接收到的脉搏血氧饱和度对睡眠障碍进行评估,同时还利用多媒体化的睡眠质量评估量表对睡眠质量进行评估。完成了生理参数的采集、传输及存储功能,并利用采集到的生理参数对个人的健康状况及睡眠质量做出了一个科学的评估。基于HTTP和Socket技术的通信模块的实现。建立手机与服务器间的通信,利用Tomcat技术构建虚拟服务器,利用Servlet技术开发服务器数据通信方法,利用JDBC研究数据库操作实现,采用线程池的形式设计客户端的并发连接。手机端通过HTTP和Socket技术,实现与服务器的连接,将个人信息及测量结果上传到服务器,以便做进一步的分析。
[Abstract]:With the rapid pace of modern life and the increasing competitive pressure, more and more people are affected by sleep. It is urgent to study new methods and techniques to evaluate the quality of sleep and to be guided scientifically. This will be of great help in improving sleep quality. At present, the use of polysomnography to monitor the physiological signals of more than 10 channels, such as EEG, electrocardiogram, electromyogram, oxygen saturation and so on, has been used to evaluate the application of sleep quality. The analysis of these signals is used to evaluate the quality of sleep. In addition, the measurement of sleep quality index is also one of the important methods of sleep evaluation. In this paper, a sleep quality evaluation system based on Android system is studied. The system realizes the hardware acquisition module of the blood oxygen saturation signal, the signal analysis algorithm module and the communication module of the mobile phone. At the same time, the Sleep quality Index scale is also implanted in the mobile phone to assist the evaluation. The realization of the hardware acquisition module of the blood oxygen saturation signal. The analog front-end circuit is built by oneself, including the probe driving circuit and the preamplifier circuit. Inverse-phase amplification and signal separation circuits, automatic gain control circuits, low-pass circuits, etc. control the emission of infrared and infrared light by time series. A large number of experiments show the ratio of transmission intensity of these two wavelengths. It is approximately linear with the value of pulse oxygen saturation (SPO _ 2). The ratio of transmitted light intensity detected is converted to the value of oxygen saturation we need. The signal receiving and signal analysis algorithm of Android mobile phone is realized. Bluetooth transmission module is added at the end of blood oxygen parameter acquisition module. The physiological data such as pulse blood oxygen saturation collected at the detection end are sent to the smartphone side of the Android system. The smartphone terminal uses Android Bluetooth API to develop the class, to open Bluetooth to the mobile phone and to search the Bluetooth equipment nearby, and so on. Realize the data transmission and display the received physiological information on the mobile phone. Then evaluate the sleep disorder according to the received pulse oxygen saturation. At the same time, the sleep quality is evaluated by using the multi-media sleep quality evaluation scale. The collection, transmission and storage functions of physiological parameters are completed. A scientific evaluation of individual health and sleep quality is made by using the collected physiological parameters. The realization of communication module based on HTTP and Socket technology, the establishment of communication between mobile phone and server, and the construction of virtual server using Tomcat technology. The server data communication method is developed by Servlet technology, the database operation is studied by JDBC, the concurrent connection of client is designed in the form of thread pool, and the connection between mobile phone and server is realized through HTTP and Socket technology. Upload personal information and measurements to the server for further analysis.
