摘要
本设计主要对人体体温、心率和血氧值进行提取分析,对系统组成中的电源模块、光源驱动模块和光电接收模块、红外温度模块、心电信号提取模块和无线传输模块进行了硬件设计。采用过采样技术对心电信号进行提取,提高了信号的稳定性和连续性。实验结果表明,该设计电路结构简单,稳定性好,测量精度高,功耗低,能够满足日常监测要求。
In the paper, the human body temperature,the heart rate and the blood oxygen value are analyzed.The system components in the power module, the light source driver module,the infrared temperature module,the ECG signal extraction module,the optical receiv- er module and the wireless transmission module are designed. The signal is extracted using the over-sampling technique, that improves the stability and continuity of the signal.The experiment results show that the design is stable and the result has high precision, which can meet the daily monitoring requirements and has a good market value.
