多功能心电信号模拟器研制
Design of Multifunctional ECG Signal Simulator
摘要
Abstract
Objective To design an ECG signal simulatur based on low-power STC microcontroller to meet the needs of research, design, produce and maintaining variety ECG detection equipment. Methods ECG signal downloaded from MIT-BIH database or collecced from classic patholopcal patient was compiled into ECG data file, and then downloaded to the built-in EEPROM of the simulator via the serial port. Meanwhile, the quantification of ECG data, the algorithm to control electrode output and the final filter were designed to achieve the ECG signal output. Results The hardware circuit design was completed. The software of microcontroller keyboard control, digital to analog converter, display interface were all finished and finally the simulator realized the function of collection, import, export of data and waveform simulation.Furthermore the results were analyzed. Conclusion The system can meet the neets of hospital biomedical engineering departments, manufacturers, research institutes, medical engineering departments and other agencies, and has great market potential and promotional value.[Chinese Medical Equipment Journal, 2011 , 32 ( 5) : 6-8]关键词
