基于TMS320F2812的心电采集系统硬件设计

Hardware Design of ECG Reccording System Based on TMS 320F2812

以DSP芯片TMS 320F2812为核心,设计了一个便携式、速度快以及具有QRS波形检测能力的心电采集系统。利用片上AD模块进行信号采集,通过移植QRS波形检测算法进行数据处理,并用内嵌的ECAN模块进行CAN总线通信,达到了减小系统体积、实时波形分析的目的。

Based on the DSP chip TMS320F2812,the paper designs a portable,high speeding ECG sampling system with QRS detection function,uses on-chip AD to sample ECG signal,ECAN module for CAN bus communication,and transplants the QRS detection algorithm into the chip.The system has small-size and real-time analyzing characteristics.
