摘　　要：设计了一种基于数字信号处理器TMS320C5515和模拟采集前端ADS1298的便携式低功耗12导联数字心电图机。心电信号由模拟前端采集后送入TMS320C5515进行预处理并通过液晶模块实时显示。同时系统配置了大容量闪存芯片,可以长时间无压缩存储心电数据,也可以通过USB接口将心电数据传送至上位机,进行信号的离线分析和诊断。系统体积小,功耗低,精度高。The design of portable and low power consumption 12-lead ECG is based on the digital signal processor TMS320C5515 and the analog front end ADS1298.The ADS1298 collects the ECG signals and deliver them to TMS320C5515. The preprocessed ECG signals are displayed real-time on a LCD and can be stored without compression for a long time. The ECG signals can also be sent to an up computer by a USB connector so that ECG data can be analyzed offline. The system has small volume, high precision and low power consumption.
