【摘要】：睡眠作為人類基本的生理活動(dòng)，對(duì)人體的生命健康起著至關(guān)重要的作用。脈搏信號(hào)作為人體重要的生理參數(shù)之一，因其包含有豐富的生理特征信息而與身體的健康狀況密切相關(guān)。因此，，如何能及時(shí)有效地對(duì)睡眠者脈搏信號(hào)進(jìn)行監(jiān)測(cè)成為了課題的研究目標(biāo)，將對(duì)于睡眠質(zhì)量的評(píng)估與分析以及對(duì)疾病的診斷提供參考依據(jù)。 論文對(duì)睡眠監(jiān)測(cè)技術(shù)的發(fā)展現(xiàn)狀、趨勢(shì)以及嵌入式系統(tǒng)的應(yīng)用等進(jìn)行了闡述，采用了嵌入式技術(shù)、無線通信及虛擬儀器相結(jié)合的方法構(gòu)建睡眠監(jiān)測(cè)平臺(tái)。主要內(nèi)容包括： （1）脈搏波基礎(chǔ)理論研究。研究了脈搏波形特征量K值與表征人體血壓、血流和微循環(huán)信息參數(shù)的關(guān)系，并將該理論在睡眠監(jiān)測(cè)平臺(tái)上進(jìn)行實(shí)現(xiàn)。 （2）硬件電路設(shè)計(jì)與調(diào)試。包括數(shù)據(jù)采集與無線傳輸模塊電路的設(shè)計(jì)。主要以LPC2103為核心，設(shè)計(jì)了外圍電路、脈搏信號(hào)調(diào)理電路以及無線發(fā)送與接收電路，通過USB轉(zhuǎn)串口電路的設(shè)計(jì)完成與上位機(jī)的通信。 （3）軟件程序設(shè)計(jì)。完成睡眠者脈搏信號(hào)采集與傳輸程序設(shè)計(jì)以及上位機(jī)虛擬儀器程序的設(shè)計(jì)。前者以ADS1.2為開發(fā)環(huán)境，通過編程實(shí)現(xiàn)對(duì)睡眠者脈搏信號(hào)的采集、A/D轉(zhuǎn)換以及信號(hào)的無線傳輸；后者以LabVIEW為開發(fā)環(huán)境，通過編程實(shí)現(xiàn)了用戶管理、脈搏信號(hào)的實(shí)時(shí)顯示與存儲(chǔ)、分析與處理以及程序發(fā)布等功能。 （4）系統(tǒng)抗干擾措施設(shè)計(jì)。完成硬件電路抗干擾與軟件濾波抗干擾設(shè)計(jì)，并利用上位機(jī)的攝像頭來采集睡眠過程中睡眠者的面部圖像與動(dòng)作信息，進(jìn)一步提高對(duì)睡眠過程監(jiān)測(cè)的可靠性。 最后，通過實(shí)驗(yàn)對(duì)睡眠監(jiān)測(cè)平臺(tái)的性能進(jìn)行分析。結(jié)果表明，硬件平臺(tái)以ARM7為核心處理器，體積小、功耗低、速度快且無需擴(kuò)展A/D轉(zhuǎn)換電路；利用無線通信模塊JF24C完成數(shù)據(jù)傳輸可避免布線，減少干擾；以LabVIEW軟件完成上位機(jī)虛擬儀器的設(shè)計(jì)，界面友好，操作簡(jiǎn)單。該平臺(tái)即解決了傳統(tǒng)監(jiān)測(cè)方式的復(fù)雜性問題，又提高了對(duì)睡眠質(zhì)量評(píng)估的可靠性。
[Abstract]:As a basic physiological activity of human beings, sleep plays a vital role in human life and health. Pulse signal is one of the important physiological parameters of human body. Because it contains abundant physiological characteristic information and is closely related to the health condition of the body, how to monitor the pulse signal in time and effectively has become the research goal of the subject. It will provide reference for the evaluation and analysis of sleep quality and the diagnosis of diseases. In this paper, the current situation and trend of sleep monitoring technology and the application of embedded system are described. The sleep monitoring platform is constructed by the combination of embedded technology, wireless communication and virtual instrument. The main contents are as follows:. 1) the basic theory of pulse wave. The relationship between the characteristic value of pulse wave K and the information parameters of blood pressure, blood flow and microcirculation is studied, and the theory is implemented on the sleep monitoring platform. 2) hardware circuit design and debugging, including the design of data acquisition and wireless transmission module circuit. The peripheral circuit, pulse signal conditioning circuit and wireless transmitting and receiving circuit are designed with LPC2103 as the core. The communication with the host computer is completed by the design of USB to serial port circuit. 3) Software programming. The program design of pulse signal acquisition and transmission of sleeper and the design of host computer virtual instrument program are completed. The former takes ADS1.2 as the development environment, The acquisition of pulse signals and wireless transmission of signals are realized by programming. The latter realizes user management, real-time display and storage of pulse signals using LabVIEW as the development environment. Analysis and processing as well as program release and other functions. 4) the design of anti-interference measures of the system. The hardware circuit anti-jamming and software filtering anti-jamming design are completed, and the camera of the upper computer is used to collect the facial image and action information of the sleeper during sleep. Further improve the reliability of sleep process monitoring. Finally, the performance of the sleep monitoring platform is analyzed through experiments. The results show that the hardware platform uses ARM7 as the core processor, small volume, low power consumption, high speed and no need to expand the A- / D conversion circuit. Using wireless communication module JF24C to complete data transmission can avoid wiring and reduce interference, LabVIEW software is used to complete the design of host computer virtual instrument, the interface is friendly and the operation is simple. The platform solves the complexity of traditional monitoring mode. It also improves the reliability of sleep quality evaluation.
