【摘要】 随着无线通信设备互联技术和电子设备小型化技术的不断进步,人类在疾病预防、康复治疗和健康监测方面的认知不断在加强、对于人体温度实时监测需求也在不断增加,这为可穿戴医疗电子设备的发展提供了很好的平台,市场的需求量也极具增加。目前可穿戴电子体温设备存在成本低的体积大、体积小的成本过高的现象,没用很好的兼顾实用性与使用体验。针对这一问题,本文基于蓝牙低功耗通信技术设计并实现了一款可穿戴电子体温计系统,尽可能兼顾低成本、低功耗、小尺寸。在对体温计系统的研究过程中,描述了系统的整个框架及细分到各个模块的器件选型、硬件电路组成及软件设计流程,对后续批量生产的可行性提出并进行验证。应用天线相关理论,并结合HFSS13.0软件,文章对适合蓝牙使用的印刷天线进行了建模仿真和天线参数优化,使其在人体佩戴的应用情境下,实现良好的无线通信效果。文章通过实验验证了优化后的天线性能,并与设计指标对比。通过研究纽扣电池的放电特性,结合无线通信和体温采集的实际需求,设计并优化了电池电量管理逻辑。通过老化放电试验,优化电量划分方案,使得优化后的电池电量管理更加适合可穿戴设备的特殊性,为同类低成本、低功耗设备的电量管理提供了参考。最后,通过本文对可穿戴电子体温计系统的功耗、测温、无线通信等电路的优化、测试和验证,体温计系统可达到的主要设计指标如下:在32℃～42℃的范围内,温度测量准确度可达到±0.1℃;使用纽扣电池供电,在待机半年后,续航时间仍可以保持500小时以上;同时,手机等智能终端与体温计可以在10米范围实现蓝牙通信并实时采集记录测温信息。更多还原

【Abstract】 With the development of wireless communication technology and electronic equipment interconnection equipment miniaturization technology,and with the increasing of disease prevention,rehabilitation and health monitoring for real-time monitoring the temperature of the human body needs,which provide a good platform for the development of wearable medical devices,and increase the market demand highly.At present,wearable electronic body temperature equipment has the phenomenon of low cost,large volume and small volume,and it does not take good account of practicability and experience.In order to solve this problem,a wearable electronic thermometer system is designed and implemented based on Bluetooth low power communication technology,which can give consideration to low cost,low power consumption and small size as far as possible.During the research process of the thermometer system concretely,we describe the whole framework of the system and the device selection,hardware circuit composition and software design process,and put forward and verify the feasibility of subsequent mass production.Using the theory of antenna correlation and combining with HFSS13.0 software,the paper makes modeling and simulation of the printed antenna for Bluetooth and optimization of antenna parameters,so that it can achieve good wireless communication effect in the application situation of the human body.The performance of the optimized antenna is verified by experiments and compared with the design index.By studying the discharge characteristics of button cells and combining the actual needs of wireless communication and temperature collection,the battery management logic is designed and optimized.Through the aging discharge test,the power division scheme is optimized,which makes the battery power management more suitable for the particularity of the wearable equipment,and provides a reference for the management of the same kind of low cost and low power equipment.Finally,through the optimization,test and verification of the power consumption,temperature measurement,wireless communication and other circuits of the wearable electronic thermometer system,the main design indexes of the thermometer system are as follows: the temperature measurement accuracy can reach up to 0.1 degrees centigrade within the range of 32 degrees centigrade to 42 degrees centigrade;the power supply of the button cells are supplied by the button cells after half a year,The endurance time can still be maintained for more than 500 hours.At the same time,the intelligent terminal and thermometer,such as mobile phone and thermometer can realize Bluetooth communication in the range of 10 meters,and collect and record the temperature measurement information in real time.更多还原
