摘要：

目的为通过心电信号检测睡眠分区及睡眠呼吸障碍等疾病，设计一种基于织物电极的心电监测系统。方法使用医用级导电织物电极代替传统电极，可在不与人体接触的情况下实时、准确地采集生理电信号，对被测者进行长时间心电监测。使用ARM11嵌入式系统代替医用主机进行数据处理、波形显示等。采用无线宽带设备代替串口线与预定主机进行通信。结果该系统可有效降低被测者的不适感，准确检测、处理、记录大量心电数据并通过无线网络实时进行远距离数据交换。结论该系统使用方便，兼顾可靠性、安全性及舒适性，适用于睡眠分析等长时间心电信号监测。

Objectives In order to detect the sleep partition and diagnose the sleep breathing disorders，this article designs a ECG monitoring system based on fabric electrodes.Methods This system collects the physiological signals real-time and accurately in the case of no-contact with the human body.Medical conductive fabric electrode is used instead of the traditional electrode and can monitor the ECG for a long time.ARM11 embedded system replaces the edical host for data processing，waveform displaying and so on.The WIFI is utilized instead of the serial line for data transmission with the specific host.Results This system can effectively reduce the discomfort of human body，can accurately detect，process，record large quantity of ECG data with the use of the wireless network for remote data-exchange in real-time.Conclusions The system is reliable，safe comfortable，convenient and is suitable for long-time ECG monitoring，such as the analysis of sleep.
