摘　　要：透射式血氧检测方法由于受到探头安放位置的限制,无法满足许多智能穿戴设备的要求,因此对于反射式血氧检测方法的研究逐渐成为了主流。文中提出了一种以MAX30100血氧饱和度集成芯片为传感器,STM32为微处理器的反射式血氧饱和度检测系统设计方案。采用MAX30100集成芯片不仅简化了电路设计、减小了系统空间体积,而且缩短了系统开发时间、降低了系统功耗,为可穿戴血氧监护产品的设计提供了参考价值。在系统的信号处理算法上,对比了几种滤波算法,选择出适合系统的最优去噪算法。实验样机测试结果证实该系统基本实现了血氧饱和度的检测功能。Due to the limitation of the probe placement, the transmissive oximetry method can not meet the requirements of many smart wearable devices. Thereiore, the research of reflective oxygen saturation detection systems has gradually become the mainstream. An oxygen saturation detection system was designed, which adopted an integrated chip MAX30100 as a sensor and STM32 as microprocessor. The use of MAX30100 not only simplified the cir cult design and reduced the system space and volume, hut also shortened the system development time and reduced system power consumption, providing the support for wearable product designs. Experimental prototype test results confirmed that the system achieved the detection of oxygen saturation.
