摘要
心电信号是人体重要的心理特征,也是现代医学的重要研究对象。文章设计了一种简便快捷的心电检测系统,包括了双导联输入、前置放大、滤波和二级放大及以单片机为核心的控制系统。最终得到计算心率所需要的数据,并由串口发送出去。
Ectrocardiosignal is an important psychological characteristic of the human body and an important object of modern medicine,In this paper,a simple and efficient detector system of Electrocardiosignal is designed,including bipolar- lead inputs,preamplification,filtering,the second amplification and the control system which is SCM as the core.Finally,we can obtain the data which is needed to calculate heart rate and tansferded by serial port.
