摘　　要：针对现有便携式心电采集系统进行长时采集时,如何通过降低数据量来解决由电池供电引起的续航不足的问题,将压缩采样原理引入系统,并对其核心部分进行硬件设计,最终以采集重构信号的R波检测率作为系统的评价标准。在MATLAB中搭建整个系统,硬件中路在Simulink模块搭建。结果表明该设计在一定压缩比情况下重构信号的R波识别率与原始信号的R波识别率基本一致,可以应用于便携式心电信号采集系统,该系统与传统心电采集系统相比具有硬件实现简单、数据量低、功耗低等优点。Aiming at the problems of power consumption and data volume in the state-of-art portable ECG acquisition system, the compressed sensing is introduced into the system, hardware circuit is designed, and the principle of the judgment is the accuracy of the R wave position test. The whole system is built in the MATLAB, and the hardware circuit is built in block of Simulink. The result indicates that the hardware circuit design can be applied to the portable ECG acquisition system, and under a certain compression ratio, the system has the advantages of simple hardware architecture, less data quantity and low power consumption.
