摘　　要： 随着近些年心血管疾病的患病率持续上升，心电信号的动态实时检测对于早期预防和诊断具有重要意义。心电图是这类疾病的主要检测方法，而传统检测仪器体积大，可移动性差，使得患者只能到医院进行检测，这样就为心电信号的及时获取增加了障碍，往往错过了最佳的发现与治疗机会。 本课题旨在利用当前普及的网络技术与电子通讯技术，开发一款基于ZigBee无线传感网络和Android平台的无线心电信号采集系统。该系统具有功耗低、成本低、重量轻、体积小等特点，通过上位机监测软件能够画出基本的心电波形，可满足临床分析与诊断的要求。 本文首先介绍了在该领域中的国内外研究现状。 其次介绍了系统的主要概念，其中包括ZigBee无线传感网络技术和Android系统的相关概念知识。 接着对系统的硬件设计做了详细的阐述。其中主要讨论了心电采集模块和ZigBee无线传感模块，介绍了其详细的参数和特点。介绍了系统硬件搭建思路。 然后讲述了整体系统的软件部分的详细开发过程，对心电模块的数据传输做了处理，设计了一款具有简单心电图绘制功能和数据发送功能的上位机软件。开发了基于Android系统的手机端检测软件。 最后针对系统的主要功能进行了实验，并取得了良好的效果。 In recent years, with the prevalence of cardiovascular disease continues to rise, dynamicreal-time detection of ECG for early prevention and diagnosis is more and more important.ECG is the primary detection method of this kind of diseases, and traditional instrumentationbulky, poor mobility, so that the patient can go to the hospital for testing, thus to increase thedifficulty of acquiring ECG signal in time, and Often missed the best treatment opportunity. This paper aims to take advantage of the current popularity of network technology andelectronic communication technologies, to develop a Wireless ECG acquisition system baseon ZigBee wireless sensor networks and the Android platform. The system has low powerconsumption, low cost, light weight, small volume, through the PC monitoring software todraw the basic ECG waveformcan meet the requirements of clinical analysis and diagnosis. First of all, This paper describes the current research.Secondly, it introduces the main concepts of the system, including the concept of knowledgerelated to ZigBee wireless sensor network technology and Android systems. Then, it introduces hardware design of the system in detail. And focuses on the ECGacquisition module and ZigBee wireless sensor module, introduced its detailed parametersand characteristics. Introduced the build ideas of system hardware. Then introduced the software part of the overall system development process in detail,and make a processing of data transmission of ECG module. And designed a PC software thathas simple ECG drawing functions and data transmission function. And developed a softwarethat base on Android system in mobile phone client. Finally, we conducted experiments to test the main function of the system, and Achievedgood results.
