摘要目的设计一种基于Android平台的健康物联网网关系统，使之可通过无线蓝牙方式获取心电数据，并在其界面上显示心电波形和心率信息，进而通过TCP协议将心率信息传输给PC端服务器。方法以ARM Cortex-A9开发板作为Android网关开发平台，结合蓝牙心电传感器和PC端服务器，完成心电信号的采集、分析和远程传输功能。网关系统硬件由主控芯片、蓝牙、Wi-Fi、存储等模块组成，软件相关功能通过在Eclipse IDE下开发Android项目实现，PC端服务器软件利用 JAVA进行设计。结果该网关系统可从蓝牙心电传感器获得单导联心电信号，并将相应的心电波形显示在其界面上，进而可通过差分阈值法计算得到实时心率后，将心率信息发送给PC端服务器。结论基于Android平台的健康物联网网关系统操作简便，功能易于拓展。实际测试结果表明，该网关系统运行稳定，可实时显示心电波形，能够准确测量心率信息，具有一定的实用价值。

Abstract：Objective To design a health networking gateway based on the Android platform, which can obtain electrocardiogram (ECG) data via Bluetooth technology, display the curves of ECG and the heart rate on its surface, and transmit the heart rate information to the server on PC through TCP protocol. Methods Using ARM Cortex-A9 development board as the development platform of the Android gateway, combined with the Bluetooth sensor of ECG and server on a PC, to complete the function of ECG collection, analysis, and remote transmission. The hardware of the gateway is made up by a controller unit, Bluetooth, Wi-Fi, storage devices and other modules. The software was developed in the Eclipse IDE as an Android project. The server on PC was developed as a JAVA project. Results The gateway obtained the ECG signals from the Bluetooth sensor of ECG and displayed the signals on its screen. After calculating the real-time heart rate by using differential threshold methods, the gateway sent the information about heart rate to the server of a PC. Conclusion The paper designed and realized both the hardware and the software of the health networking gateway based on an Android application program, which obtains ECG signals by Bluetooth and transmits the heart rate information to the remote server by TCP. The system of the IOT gateway is simple to operate and easy to be expanded. The test shows the gateway system operates stably. The curve of real-time ECG can display on the screen and the heart rate is accurate.
