摘要：

为实现对人体心电信号的实时采集,设计了一种基于ADS1293的心电信号采集系统,系统主要由ADS1293 信号采集前端和MSP430单片机控制电路组成。ADS1293对心电信号进行24位的高精度模/数转换,由SPI接口方式发送给MSP430进行分析处理,最终通过MSP430的USB接口发送到便携式显示设备实时显示波形。该系统为便携式、低功耗的心电信号采集系统提供了技术支持,具有广泛的应用前景。

Abstract:

An ECG signal acquisition system based on ADS1293 is designed to realize real-time acquisition of the ECG signal from human body.The system consists mainly of the signal acquisition module ADS1293 and the main control module MSP430.The analog-to-digital conversion of ECG signal is executed by 24-bit high-precision chip ADS1293.The converted signal is sent to the MSP430 for analysis via SPI,and then transmitted to portable monitor by USB.The system has the characteristics of ultra-low power consumption,small size and portability.
