资料介绍

首先介绍PPG法采集心率信号,然后设计了FIR滤波器并分析了HRV算法原理,引入了定点运算来实现FIR滤波、HRV等运算,可以满足在低功耗处理器MSP430上实时处理。针对传统的心率变异测量只能单次测量、不能有效反应使用者的真实生理参数问题,引入连续测量的思想,将用户连续心率变异数据进行存储,需要时可以导出进行分析。系统具有实时性高、功耗低、成本低等特点,测量准确,具有较好的应用前景。

In the paper,PPG method is introduced to collect heart rate signals,and then FIR filter is designed and the principle of HRV algorithm is last,The fixed-point operation is introduced to achieve FIR filter and HRV calculation,which can achieve the real-time processing on the traditional heart rate variability analyzer can only achieve single measurement that have low reliability,,the idea of continuous measurement is HRV data is stored in the flash and the user can export these data for observation or research when is system has high real-time performance,low-power consumption,low price and low cost and it has a good application prospect.
