基于MSP430的人体健康记录仪硬件系统设计

The Hardware System Design of the Human Health Recorder Based on MSP430

本文所述人体健康记录仪以低功耗控制器MSP430F169为核心,利用指夹透射式血氧探头在血液脉动变化时吸光强度不同的原理进行血氧饱和度测量。系统记录动脉脉动的频率作为心率,通过温度传感器测量体温,利用加速度传感器实现运动计步,并根据相关算法进行热量消耗的测算。所设计的人体健康记录仪能够及时记录人们关心的上述生理和运动参数,给使用者获得有益的健康指导。

With low power MCU MSP430F169 as the core controller, the human health recorder makes use of a transmissive finger photoelectric sensor which reflects different absorption intensity when blood pulsation to get the blood oxygen saturation （SpO2）and the pulsation frequency is detected as the heart rate. The recorder uses temperature sensor and acceleration sensor to measure body temperature and motion steps, and the calorie consumption is estimated according related algorithms The human health recorder can record the about in time, and give the user a good heal physiological and exercise parameters which people care th guide.
