基于LabVIEW的心电采集设计

Design of ECG Acquisition Based on LabVIEW

为配合所设计柔性心电监测系统的下位机部分,设计一种心电数据处理系统,基于LabVIEW编程实现心电信号采样数据的分析。按照规定的协议,下位机通过蓝牙/串口将采集到的数据传输至上位机,上位机完成心电信号的数据可视化、实时测量心率、血氧饱和度以及体温等生理参数,对心电波形进行数字滤波处理、保存心电数据、读取二进制文件数据并重绘心电波形图。经分析测试,软件使用成本低、稳定性较好,基本实现用户短距离实时心电监测。

In order to cooperate with the lower computer part of the flexible ECG monitoring system designed, an ECG data processing system is designed, which realizes the analysis of ECG signal sampling data based on LabVIEW programming. According to the specified protocol, the lower computer will transmit the collected data to the upper computer through Bluetooth/serial port. The upper com-puter completes the data visualization of ECG signal, real-time measurement of heart rate, oxygen saturation, body temperature and other physiological parameters, digital filtering processing of ECG waveform, saving ECG data, reading the binary file data and redrawing the ECG waveform. Through analysis and test, the software has the advantages of low cost and good stability, and can basically realize short-distance real-time ECG monitoring for users.
