摘要/Abstract

摘要：

为推进现代心电监护向数字化、智能化发展，使心率精确显示，提出一种基于C8051F320单片机的心电监护系统。该系统采用放大滤波电路对ECG(Electrocardiograph）信号进行处理以实现心电信号的放大、噪声的消除等功能，并利用单片机控制LCD（Liquid Crystal Display）对其进行实时显示，借助SD卡存储心电图数据，最后将数据传送给PC机采用LabVIEW软件实现虚拟仪器功能。经过实验证明，此虚拟仪器系统操作简单、功能设置灵活，适用于人体心电信号采集、实时显示以及后期分析。

Abstract:

In order to promote the digital and intelligent development of modern ECG(Electrocardiograph) monitoring system，we describes an ECG monitoring system based on the SCM C8051F320. First use amplifier and filter circuit as the ECG processing to amplify ECG signal and filter noises; then we LCD（Liquid Crystal Display） to real-time display the heart rate and we SD card to store ECG data; finally ECG data is transmitted to the PC terminal, the PC uses LabVIEW to realize virtual instrument function. Test results show that this virtual instrument system is simple operation and feasible function setting, which is suitable for acquisition, real-time display and later analyzing of human ECG signal.

Key words: electronic technology, electrocardiograph(ECG) monitoring system, LabVIEW virtual instrument, data acquisition, C8051F320
