【摘要】 心血管疾病是威胁人类健康和生命的主要疾病之一。动态心电图(DCG)可对心脏病患者的心电活动进行连续24小时的跟踪记录,是临床诊断心血管疾病的重要方法。因此,进行高性能动态监护系统的研究在临床上具有重要的意义。而近年来嵌入式系统技术的飞速发展也为展开这类研究提供了良好的技术条件。 为此,本论文对基于高性能嵌入式微处理器的便携式动态心电监护仪及其对心电的分析处理进行了深入研究:根据心电信号特征,设计性能优良的心电数据采集模块;选用高性能、低功耗的ARM微处理器S3C44BOX和大容量Flash存储器设计中央处理模块,对采集的心电信号进行分析处理和记录,同时使用液晶显示配合按键为用户提供友好的人机接口,实现连续动态的心电监护和报警功能;通过对心电波形特征和常用心电分析处理算法的对比分析和研究,设计适用于本嵌入式系统的实时心电分析处理算法;采用现今流行USB接口技术,实现对心电数据的传输。 论文对以上各项工作进行了详细的阐述,基本达到设计要求,为进一步的产品实际应用开发奠定了良好的基础。更多还原

【Abstract】 Cardiovascular disease is one of the most dangerous threats to human health.Dynamic electrocardiogram (DCG) can continuously trace patient’s heart activity for 24 hours and is escential for clinical diagnosis of cardiovascular disease. Therefore,it is of great significance to research high-performance dynamic electrocardiogram monitor in clinic.The fast development of embedded system has also provided perfect technology for this research recently.Therefore, a portable dynamic electrocardiogram monitor based on high performance embedded CPU and its’ ECG analysis algorithm are lucubrated in this thesis: According to the features of ECG signals, an ECG collecting module is designed; S3C44B0X, a high-performance and low power Arm CPU is selected to design the central processing module for ECG signals processing and analysis .In this module, a Flash memory is extended to record the sampling ECG signals. The LCD display and keyboard provide a friendly Human Computer Interface for users. With these parts , this module realizes the continuous dynamic monitor and alarm functions; According to the analysis of ECG waves’ characteristics and existent ECG analysis algorithm, a real time ECG analysis algorithm is proposed for this embedded system ; The present popular USB bus interface is applied to transport ECG signals in the Flash memory.All this research works are described in details in this thesis and arrive at the demand of design basically. The studies of this thesis also have established a good basis for the practical development.更多还原
