人体生理参数测量系统低功耗设计与实现

摘要

为解决无市电情况下人体生理参数的长期监测问题,采用近年新推出的光反射器NJL5501R和心电监护模拟前端芯片AD8232,利用动态电源管理、动态时钟频率控制等低功耗技术,设计了一种以STM32L152微处理器为核心的人体生理参数测量系统.实验结果表明:该系统能够完成人体血氧、心电、温度等参数的测量,具有低功耗、小体积的特点,可实现生理参数的长时间监测.%In order to solve the problem of long-term monitoring on human physiological parameters in the absence of city electricity,adopt new light reflector NJL5501R and analog front-end chip for ECG monitoring AD8232 at present,design a measurement system of human physiological parameters based on STM32L152,using low power consumption technology,such as dynamic power management,dynamic clock frequency control. The experimental results show that the system can complete the measurement of human blood oxygen,ECG and temperature parameters,features with low power consumption,small volume,it can monitor the physiological parameters long-term.
