心电信号与气象因子同步采集系统的研究

研究发现,气象因子的变化会影响人体生理参数的改变。目前的研究都是基于事后的统计分析。为此设计了一种动态采集系统,用于对气象因子和心电信号进行24h的同步采集,从而揭示气象因子变化与心电信号之间的对应关系。系统选W78LE516单片机和CPLD来构造控制电路,用读写速度快、功耗低的低电压外部数据存储器CF卡存储采集完的信号。最终采集到的数据可以在上位机上显示波形。

The research of the simultaneous acquisition system of meteorological factors and ECG signal

Changes in meteorological factors will affect the body's physiological parameters change are found. The current study are based on the subsequent statistical analysis. A dynamic acquisition system is design,used for meteorological factors and a 24 h ECG synchronization of the collection,and thus reveal the correspondence in meteorological factors and the ECG signal. The system select W78LE516 MCU and CPLD to construct the control circuit and use quickly read and write low power consumption,low-voltage exter...
