【摘要】：从传统中华医学著名的脉诊，到现代医学对心血管系统及其疾病的深入研究，充分说明了人体脉搏与疾病尤其是心血管类疾病之间的密切关系。脉搏信号中含有许多生理信息，对脉搏进行检测和信息分析，便于对人体生理健康状况的变化趋势及早了解，从而进行早防御、早治疗，尤其是对心血管疾病和慢性疾病的预防和诊治有着重要的指导作用。本文采用K值选波法进行脉搏信号的提取，在宏观上描述出脉搏波的平均特征，并在时频域中研究了脉搏波的特征，通过对不同年龄段人群的脉搏波形图和频谱图的对比，找出波形和能量在不同年龄段人群中的一般变化规律。在脉象脉图理论的基础上，总结出不同脉象与可能出现的心血管疾病之间的联系。本文分析研究了现有的脉搏信号测量技术及其处理方法，以单片机作为下位机，利用AT89C52单片机设计和实现了脉搏信号采集装置，以PC机作为上位机，利用LabVIEW7.0强大的数据库支持特性，对脉搏信号进行数字滤波和信号处理，实现了脉搏信号的采集，脉搏波形的实时显示以及数据的存储等功能。在本文最后，，通过将现代纺织技术与电子技术进行融合，在传统的服装上实现对人体脉搏的监测，增加服装的功能性。采用导电纱作为电路模块间的连接部件，克服了传统电子服装不耐水洗，柔软性差、服装舒适性差的难点。电子器件可以根据服装的款式灵活配置，服装的实用性得到加强。本课题要求将电子设备嵌入到服装当中，且服装应具有柔软、弹性、耐用和可清洗等特点，因此要解决服装中存在的一些问题，比如导线连接的可靠性、服装的舒适性和电路的防短路问题等。
[Abstract]:From the famous pulse diagnosis in traditional Chinese medicine to the in-depth study of cardiovascular system and its diseases in modern medicine, the close relationship between human pulse and diseases, especially cardiovascular diseases, is fully explained. The pulse signal contains a lot of physiological information, and the pulse is detected and analyzed in order to understand the changing trend of human physical health status as soon as possible, so as to carry out early defense and early treatment. In particular, it plays an important guiding role in the prevention, diagnosis and treatment of cardiovascular diseases and chronic diseases. In this paper, the K value wave selection method is used to extract the pulse signal, and the average characteristics of the pulse wave are described macroscopically, and the characteristics of the pulse wave are studied in the time and frequency domain. The pulse waveform and spectrum of different age groups are compared. The general variation of waveform and energy in different age groups was found out. Based on the theory of pulse image, the relationship between different pulse images and possible cardiovascular diseases is summarized. In this paper, the existing pulse signal measurement technology and its processing method are analyzed and studied. Using single chip microcomputer as the lower computer, the pulse signal acquisition device is designed and realized by using AT89C52 single chip microcomputer, and the PC is used as the upper computer. Using the powerful database support characteristics of LabVIEW7.0, the pulse signal is digitally filtered and processed, and the functions of pulse signal acquisition, real-time display of pulse waveform and data storage are realized. At the end of this paper, through the integration of modern textile technology and electronic technology, the pulse monitoring of human body is realized in the traditional clothing, and the functionality of clothing is increased. The conductive yarn is used as the connecting component between circuit modules to overcome the difficulties of traditional electronic clothing, such as unwashable, poor softness and poor comfort. Electronic devices can be flexibly configured according to the style of clothing, and the practicability of clothing is strengthened. This topic requires the electronic equipment to be embedded in the clothing, and the clothing should have the characteristics of softness, elasticity, durability and cleanability, so it is necessary to solve some problems existing in the clothing, such as the reliability of wire connection. The comfort of clothing and the short circuit prevention of circuit, etc.
