摘要
介绍一种心电信号采集存储系统,该系统利用MSP430F5529串行外围接口总线与SD卡相连,解决了便携式生理信号监测系统长时间对人体健康检测所产生的大量数据问题。USB接口与文件系统设计,使得写入SD卡的心电数据能够在上位机中得到正确访问,方便进一步处理和分析。该系统适用于大容量的现场采集、存储和读取,并在便携式心电监护仪上得到了应用。经实验,该系统完全满足要求,实现了对人体心电信号实时采集、显示、存储以及后期分析。
An ECG signal acquisition and storage system is introduced,in which MSP430F5529 serial peripheral interface（SPI）bus is connected to SD card in this system to solve the mass data problem generated from long time human health detection by portable physiological signal monitoring system. The design of USB interface and file system makes the ECG data written into the SD card can be accessed correctly in the host computer,and then processed and analyzed further. This system is suitable for large capacity on-site collection,storage and read,and has been applied to the portable ECG monitor. The experimental results show this system can meet the requirements entirely,and realize the real-time acquisition,display,storage and later analysis of human eletrocardiosignal.
