摘　　要：介绍了心电信号检测系统的设计,利用心电电极片和三输入屏蔽导联线,采用标准导联的方式实现对人体心电信号采集,然后通过多级放大滤波电路模块对心电信号进行处理,给出了具体的电路设计方案,完成相关数据测试,并实现心电信号的有效输出和显示。软件上对采集的数据进行数字滤波,用LabVIEW软件实现上位机的实时存储、显示等功能。研制的心电信号检测系统具有响应速度快、性能可靠、使用方便、成本低等特点,可为广大普通用户和家庭中的心电监护以及其它微弱信号采集等提供帮助。Introduces the ECG signal detection system design, use ECG electrodes and three input shielding cable, using the way of standard lead to achieve uptake of ECG signal on the human body, and then through the multistage filtering and amplifying circuit module for ECG signal processing, given the specific circuit design, complete the relevant test data, and realization the output and display of ECG signal. The collected data are digitally filtered on the software, and LabVIEW software is used to realize the real-time storage, display and other functions of the upper computer. ECG signal detection system proposed in this paper has a fast response speed, reliable performance, convenient use, simple structure, low cost, ECG monitoring fields can be applied to common users and in the family.
