摘要
主要针对人体心电信号微弱,易干扰,不易放大的特点,设计了心电信号采集放大的前端电路,并以此为基础进行模数转换,利用USB接口实现数据的PC上传,并对采集到心电信号数据进行分析和处理,同时存储、回显心电波形。设计了基于MFC可视化的上位机软件,具有简单,易用的特性。系统电路具有小型化,模块化,低功耗的特点,适用于家庭便携式的心电监。
In this paper,designed a ECG signal acquisition front-end amplify circuit and analog-digital conversion.In order to deal with the weak ECG signal for the human body,must be careful of the interference.The data is presented to PC by the popular USB interface.And then,analyze and process the collected data,storage and echo ECG waveform.PC software based on MFC has easy-to-use features.The entire circuit is small,modular,portable for ECG monitor in home.
