Abstract

In this study, the ECG signal were measured as noiseless with Ag/AgCl electrodes, then converted digital data using pulse code modulation (PCM) technique. The digital data were then sent to receiver where it is in 433 MHz FM/FSK transmitter, which has 10 mW output power and 9.6 Kps transmission speed. At the receiver, the digital data were reconverted to analog signal to monitor and record on the PC with Sonic Foundry Sound Forge 6.0 program. The power spectrum of measured ECG signal was formed using Matlab program. As a result, the medical supporting system is realized for monitoring the ECG signal on PC of human with chronic heart disease in their living surroundings.

摘要

在本研究中，使用银/氯化银电极将心电图信号测量为无噪声信号，然后使用脉冲编码调制（PCM）技术将其转换为数字数据。接着，数字数据被发送到接收器，该接收器位于433 MHz调频/频移键控发射机中，其输出功率为10 mW，传输速度为9.6 Kbps。在接收器处，数字数据被重新转换为模拟信号，以便使用Sonic Foundry Sound Forge 6.0程序在个人计算机上进行监测和记录。使用Matlab程序形成测量的心电图信号的功率谱。结果，实现了医疗支持系统，用于在患有慢性心脏病的人的生活环境中，在个人计算机上监测其心电图信号。
