基于无线传输技术的人体脉搏采集分析系统

Human Body Pulse Acquisition and Analysis System Based on wireless Transmission Technology

设计了一种人体脉搏无线检测系统,该系统实现了人体脉搏的采集,滤波,无线传输等功能。信号采集硬件以MSP430单片机为控制核心,采集脉搏数据经过滤波、A/D转换,通过无线传输模块传入计算机。上位机软件利用虚拟仪器技术编程,实现了实时数据的采集、存储和波形显示。通过计算机对脉搏信号进行特征提取、分析和初步健康诊断。系统拥有便携、低功耗、成本低的特点,既可用于脉搏信号研究也可用于临床和家庭保健中的脉搏检测。

This paper designed a kind of human blood pulse wireless - signal acquisition and analysis system, this system has achieved the functions of data collecting, filtering and wireless transmitting, etc. The hardware of signal acqusition is controlled by MSP430 singlechip, which sampling blood pulse data, filtering,during the A/D conversion and sending data to computer by wireless communication modules. The software has used techniques of Virtual Instrument,which has got real time data, made the storage and the waveform display, extracted the features of data and analysized the signal of human blood pulse for the preliminary diagnosis of health. This system has the features of portable, low - power, and low - expense, it is used not only for the research, but also in the clinical and family places.
