利用脉搏图像传感器和MP425数据采集卡设计了一种多信息同步采集系统,实现了脉搏动态图像和心电信号的同步采集,并运用Matlab软件的数据可视化功能,实现了两种信号的同步动态再现;研究结果表明,该同步采集系统具有稳定的可靠性和精确性,为揭示脉搏信号和心电信号之间的动态联系与规律提供了一种新的研究思路,同时也为提取反映人体亚健康状态脉搏心电变化的特征参量奠定了良好基础。

A Multi-Information and synchronous acquisition system based on pulse image sensor and MP425 data acquisition card was designed,which achieved the synchronous acquisition of dynamic pulse images and ECG signal.And the dynamic synchronization representation of two signals was realized by using the data visualization capabilities of Matlab software.The results show that this system has a stable reliability and accuracy,which can provide a new research ideas for revealing the dynamic connection and law between pulse and ECG signals,and also establish a good foundation for extracting the features of pulse and ECG changes which reflect human sub-health state.
