摘　　要：生物电信号诸如心电信号与人体健康状况息息相关。本课题以心电信号为研究对象,设计并实现了心电信号在线检测和分析系统。首先,采用了AD8232模块,实现心电信号的实时检测、滤波和放大;其次,分别采用差分阈值法和K-means算法对心电信号进行分析,计算得到心率变化;最后,设计了面向用户的人机交互界面,将检测到的信号和分析计算结果,实时反馈给使用者。The neurophysiological signals such as ECG (Electrocardiogram) are closely related to human health. In this study, a real-time detection and analysis system for ECG is designed and implemented, with ECG as research object. Firstly, the AD8232 module is adopted to realize the real-time detection, filtering and amplification of ECG signals. Secondly, the difference threshold method and the K-means algorithm are used to analyze the ECG signals, and the heart rate variance is calculated. Finally, a user-oriented interface is designed to illustrate the detected signals and the analysis and calculation results for users.
