基于ADS1298R的ECG信号采集终端的设计

摘要

该文以TI公司的MSP430F6659和ADS1298R芯片为核心，设计了面向家庭健康监护的心电信号采集与显示终端。首先介绍了心电采集的基本原理，然后以MSP430F6659和ADS1298R芯片为核心阐述了系统总体方案，并介绍了其外围接口、心电波形LCD实时显示、数据存储、USB与上位机通信等模块。所设计的ECG信号采集终端具有体积小、功耗低等特点。%The home health monitoring of the ECG signal acquisition and display terminal is designed with MSP430F6659 and ADS1298R chip of TI company. The basic principles of ECG col ection is introduced in the beginning, and then the overal scheme of the system is described by MSP430F6659 and ADS1298R chip as the core, and the modules peripheral interface, real-time display in LCD, data storage and USB are introduced. The ECG signal acquisition terminal designed in this paper has the characteristics of smal size, low power consumption and so on.
