利用分布式光纤布拉格光栅(FBG)传感器进行人体温度的检测,研制了智能服装样衣,重点从人体生理学基础理论、人体热平衡及空气热传递理论等方面研究智能服装在穿着过程中的热传递机理,对热传递过程进行分析和研究,从理论上建立起人体皮肤-空气-服装(传感器)三者之间的热传递数学模型,为智能服装中分布式FBG传感器人体温度测量提供理论依据,并提出了智能服装中Houdas改进模型用以确定分布式FBG传感器测量点,最后阐述了智能服装用光纤植入服装的方法。在实验研究中,智能服装样衣中分布式FBG传感器所测人体温度与温度场模拟数据对照差异无统计学意义,据此可以得出分布式FBG传感器所测温度可以作为临床医学人体腋下温度使用。
The use of distributed fiber Bragg grating (FBG) sensor to detect the body temperature, developed a smart clothing sample clothing, focusing on the basic theory of human physiology, the human body heat balance and air heat transfer theory of intelligent clothing in the process of wearing heat transfer mechanism , The heat transfer process is analyzed and studied. The mathematical model of heat transfer between human skin and air - clothing (sensor) is theoretically established, which provides a theoretical basis for the body temperature measurement of distributed FBG sensor in smart clothing. The improved model of Houdas in smart apparel is proposed to determine the measuring points of distributed FBG sensors. Finally, the method of implanting smart apparel fibers with optical fibers is presented. In the experimental study, there was no significant difference between simulated temperature data and temperature data measured by the distributed FBG sensor in smart clothing sample clothes. From this we can conclude that the temperature measured by the distributed FBG sensor can be used as clinical underarm temperature use.
