摘要
针对目前健康监测终端设备的弊端,设计了一种便携式多生理参数监测终端。终端设备以ARM微处理器STM32F405为控制与信号处理核心,通过对多种传感器采集的信号进行实时处理和分析,获取脉率、呼吸、血氧饱和度(SPO_2)、脉搏传输时间(PTT)、心电图(ECG)以及光电容积脉搏波(PPG)信息,可实时显示生理参数和波形信息,通过触控屏完成人机交互功能,可方便实现手持式和穿戴式测量方式的自由切换。测量数据可本地存储或者通过蓝牙、ZigBee无线发送。通过实验测试,该设备测量的生理参数数据准确可靠。
Aiming at defects of health monitoring end devices at present, a portable multi-physiological parameter monitoring end device is designed. Control and signal processing functions are realized through ARM microprocessor STM32F405;information such as pulse rate, respiratory rate, surplus pulse 02, （ SPO2 ） pulse transmission time（PTT）, electrocardiogram （ECG）, photoplethysmography （PPG） can be obtained by real time processing and analyzing signal acquired by sensors;physiological parameters and waveforms can be displayed in real-time; man-machine interactive function can be realized through touch screen; hand-held and wearable measurement modes can be freely switched as needed. Measurement data can be saved locally or wirelessly sent through Bluetooth or Zig Bee. Experiments show that physiological parameters measured by the end device are accurate and reliable.
