摘要
介绍12导联数字心电图机研制开发,采用双CPU架构,包括数字信号处理TMS320F206和微控制器AT89C55。该仪器利用数字信号处理器TMS320F206PZ实现实时对心电信号进行滤波和心电参数计算;热敏打印心电图形和检测结果;存储病人的心电数据,心电图形的回放打印,与PC机进行数据通主,建立病人的心电数据库,进一步研究分析。
In this paper,design of DSP-based electrocardiograph instrument was presented,which is based on dual-CPU structure with a digital signal processor TMS320F206PZ and a microcontroller AT89C55.This instrument functions features simultaneous data acquisition of the 12 standard leads,signal preprocessing,wave detection and electrocardiograph（ECG） parameter measurement and thermo-dot printing ECG curve.The communication module was interfaced to personal computers for further ECG data storage and analysis.
