摘要
目的:设计一种安装在耳机上的实时检测人体体温及脉搏波信号的辅助装置,使人们在不影响生活工作的同时,轻松便捷地关注自己的健康状况。方法:置于耳机上的反射式光电传感器采集脉搏波信号,热电堆红外温度传感器采集体温信号。信号经过滤波、放大和A/D转换后,利用嵌入在耳机内的单片机分别对脉搏波及体温信号进行处理,以得到心率和体温数据。并将处理后的脉搏波波形、心率数据及体温数据显示在液晶显示屏上,还可通过SD卡接口进行数据传输及存储。结果:经过实际测试,传感器能够测得人体耳部体温、提取耳部脉搏波信号,具有测量人体脉搏波、心率及体温的功能。结论:该耳机装置是一种可为用户提供实时检测体温、脉搏波及心率的便携式装置。
Objective： Temperature parameter is one-of-the important indexes of human body system function. So designing a signal of auxiliary device installed in the headset which can independently real-time monitoring the human body temperature and pulse wave is necessary for user. Methods： Pulse wave signal was collected by reflection type pulse wave optical current transducer, and temperature signal was collected by thermopile infrared temperature sensor. Pulse signals, after filtered, enlarged and A/D converted, was transformed into SCM which in headset and computed heart rate and temperature data by digital processing pulse wave and temperature signal. Processing and storing signal and data, finally the treatment of pulse waveforms, heart rate and temperature data is displayed on the LCD screen of the supporting device, and transmission and storage by the supporting device in the SD card interface data. Results： After the actual test, the sensor can be measured by ear temperature and pulse wave, and output them. The headphone has the function of measuring the pulse, temperature and heart rate. Conclusion： A headphones device monitoring human body temperature and pulse wave can provide a real-time detection of the portable device of the pulse wave and heart rate.
