浅析胎儿心电监护系统
摘要：作为保障围产期孕妇和胎儿安全、实现优生优育的重要手段之一——胎儿的心电监护，它的作用是对围产期胎儿心电信号的监护，进而了解胎儿的心脏活动状况。胎儿心电监护主要包含两部分，分别是胎儿心电信号的提取和胎儿心电监护系统的研究，本文主要研究胎儿心电信号的提取与处理中的应用，然后进一步研究胎儿的监护系统，创建了一种基于 PC 机的胎儿心电监护系统。该系统实现了两个功能：数据采集和实时处理以及存储功能，实现了对用户及数据信息的管理。

Analysis of fetal ECG monitoring system
Abstract: as an important means to protect the pregnant women and fetuses healthy of fetal ECG monitoring, it is the role of monitoring of perinatal fetal ECG signal, and then understand the fetal heart activity status. The fetal ECG monitoring consists of two parts, respectively is the study of fetal ECG extraction and fetal ECG monitoring system, this paper mainly studies the application of extraction and processing of fetal ECG signal in the monitoring system, and further study of the fetus, creating a fetal ECG monitoring system based on PC. The system realizes two functions: data acquisition, real-time processing and storage function, and realizes the management of user and data information.
Key words: fetal electrocardiogram; adaptive line enhancement; fetal ECG monitoring system
