便携式同步心电记录器及其远程通信系统的研究

Study of portable synchronous ECG recorder and its long-distance communication system

介绍了一种便捷的远程心电通讯系统，它由便携式心电采集记录器和医生工作站以及公用市话网组成。本文还介绍了一种声耦合数据通讯中调制解调方式——脉冲边沿调制与解调。系统结构合理，操作方便，管理功能强。采集／记录器采用philips80C552作为中央处理器，体积小，成本低，可靠性高，便于携带。与市话网采用声耦合方式，使推广应用更为方便。

This paper presents a convenient long-distance ECG communication system. It is made up of portable ECG recorder,hospital work station and public telephone network This paper also introduces a kind of modulation and demodulation method in sound coupling communication- pulse edge modulation and demodulation. This system has rational structure, convenient operation and strong management power. A philips 80C552 used as CPU in the recoder which is portable,cheap and reliable
