选择适于伪周期信号处理的模板函数匹配方法进行时域的在线参数估计

可实现对脉搏波信号特征的分析计算

并使系统能以简单结构满足对脉搏波信号的实时检测要求。实验表明:本系统设计和数据处理方法有效可行。

Abstract

The simplofied realization method of pulse wave real-time detecting and parameters analysis system for daily health surveillance is described.Based on C8051 series MCU and integrated PVDF piezoelectric sensor

the radial artery pressure signals are collected.After filtering and smoothing the sampling data

the template function matching method adapted to pseudo-periodic signal is applied to estimate the pulse wave characteristic parameters online.As the filtering and the characteristic analysis for pulse signal processing both are carried out in time-domain

The pulse wave’s real time examination is fulfilled by using the simplest hardware.The experiment shows that the method of data processing is effective and the system is feasible.
