摘要
心电信号作为人体的一种重要的生理信号,反映着人体的健康状况。自行设计并制作心电信号采集、放大、抗混叠滤波等电路,得到满足数据采集卡USB-6008要求的模拟心电信号,并对模拟心电信号进行A/D(模/数)转换,得到数字形式的心电信号。利用虚拟仪器开发平台LabVIEW 2009对数字心电信号进行多分辨率分析(小波分析),得到心电信号在各分辨率空间的组成成分,并从中选择体现心电信号特点的成分重新构建心电信号,实现对心电信号进行小波滤波的目的,最终在PC机上获得效果良好的心电图。该研究通过有限的资金投入,将家用电脑拓展为心电监测仪器。
As an important physiological signal of the human body, ECG（Electrocardiogram Signal, ECG）reflects the state of health of the human body. The project designed and produced circuit such as ECG signal acquisition, amplification and anti-aliasing filter to meet the data acquisition card USB-6008 requirements and analog ECG signal A / D （ analog / digital） conversion to obtain the ECG digital form use virtual instrument LabVIEW 2009 development platform multi-resolution digital ECG analysis （wavelet analysis） to ob- tain the components of the ECG signal in each resolution spatial and select these components ingredients which reflects the characteris- tics of ECG to rebuild ECG, and achieve ECG wavelet filtering purpose, and eventually get good ECG on a PC. With limited funding, the research will expand home computer to ECG monitoring instruments.
