摘要

利用MAX30102设计了一种无线人体生理参数的装置，该装置以STM32系列单片机为核心，通过MAX30102模采用光电容积脉搏描述法（PPG）采集食指末梢动脉的脉搏波信号，然后将源信号进行数字滤波处理处理和标度转换，得到血氧和心率等测量值，并且可以与手机进行蓝牙通信。通过标定对比，血氧饱和度测量范围35%～100% （正常人体动脉血的血氧饱和度为98%），分辨率为1%，精度为70%～100% ± 2%，小于70%无定义，在脉搏充盈度为0.4%时，能正确显示血氧饱和度，心率测量范围0～150次/分钟（成人正常心率为60～100次/分钟），误差不超过1%，体温范围0～50℃，分辨率0.1℃，误差不超过0.2%。

Abstract:

A wireless device for human physiological parameters is designed by using max31002, the device is STM32 series microcontroller as the core, through the MAX30102 model using photocapacity pulse description method (PPG) to collect the pulse wave signal of the index finger ending artery, and then the source signal digital filtering processing and scale conversion, to obtain blood oxygen and heart rate measurements, and can communicate with the mobile phone Bluetooth. By calibration comparison, the measurement range of blood oxygen saturation is 35% to 100% (the blood oxygen saturation of normal human arterial blood is 98%), the resolution is 1%, the accuracy is 70% to 100% ± 2%, less than 70% is undefined, and the pulse charge is 0 .4%, can correctly show oxygen saturation, heart rate measurement range of 0 to 150 times/minute (adult normal heart rate of 60 to 100 times/minute), the error is not more than 1%, the temperature range 0 to 50 ℃, the resolution of 0.1 ℃, the error is not more than 0.2%.
