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。
In order to promote the digital and intelligent development of modem ECG (Electrocardiograph) mo- nitoring 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 Dis- play) 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 in- strument system is simple operation and feasible function setting, which is suitable for acquisition, real-time dis- play and later analyzing of human ECG signal.
