多功能无线式心脏监测系统

Multi-Function Wireless Cardiac Guardianship & Examination System

本系统有别于传统的心电监护，患者的心电信号采用无线电发射／接收方式，一个主机可同时监护多个病人。本文主要介绍该系统的发射、接收、处理３大部分的组成、工作原理及弱信号获取、非线性失真、抗干扰、稳定性和实时速度等几项关键技术的解决。

This system is different from the conventionalelectrocardiac monitor. The patients' electrocardiacsignal is transmitted/received in the form of radiowave. We can guard several patients at the same timewith one monitor. This paper mainly presents thecomPOsition &. working principle of the three parts transmitting, receiving and processing of the system.The solutions of several critical technologies such asextraction from weak signal, non - linear distortion, anti - disturbance, stability and real - time speed etc.are also introduced.
