This paper presents the design of a novel wireless sensor network structure to monitor patients with chronic diseases in their own homes through a remote monitoring system of physiological signals. Currently, most of the monitoring systems send patients' data to a hospital with the aid of personal computers (PC) located in the patients' home. Here, we present a new design which eliminates the need for a PC. The proposed remote monitoring system is a wireless sensor network with the nodes of the network installed in the patients' homes. These nodes are then connected to a central node located at a hospital through an Internet connection. The nodes of the proposed wireless sensor network are created by using a combination of ECG sensors, MSP430 microcontrollers, a CC2500 low-power wireless radio, and a network protocol called the SimpliciTI protocol. ECG signals are first sampled by a small portable device which each patient carries. The captured signals are then wirelessly transmitted to an access point located within the patients' home. This connectivity is based on wireless data transmission at 2.4-GHz frequency. The access point is also a small box attached to the Internet through a home asynchronous digital subscriber line router. Afterwards, the data are sent to the hospital via the Internet in real time for analysis and/or storage. The benefits of this remote monitoring are wide ranging: the patients can continue their normal lives, they do not need a PC all of the time, their risk of infection is reduced, costs significantly decrease for the hospital, and clinicians can check data in a short time.
本文提出了一种新颖的无线传感器网络结构设计，通过远程生理信号监测系统，实现在患者家中对慢性病患者的监测。目前，大多数监测系统通过位于患者家中的个人计算机（PC）将患者数据发送到医院。在这里，我们提出了一种新的设计，无需使用 PC。所提出的远程监测系统是一个具有网络节点的无线传感器网络，这些节点安装在患者家中。然后，这些节点通过互联网连接到医院的中央节点。所提出的无线传感器网络节点是通过 ECG 传感器、MSP430 微控制器、CC2500 低功耗无线电台以及一种名为 SimpliciTI 协议的网络协议的组合创建的。ECG 信号首先由每个患者携带的小型便携式设备进行采样。然后，捕获的信号通过无线传输到位于患者家中的接入点。这种连接是基于在 2.4GHz 频率下的无线数据传输。接入点也是一个通过家庭异步数字用户线路由器连接到互联网的小盒子。之后，数据通过互联网实时发送到医院进行分析和/或存储。这种远程监测的好处是多方面的：患者可以继续正常生活，无需一直使用 PC，感染风险降低，医院成本显著降低，临床医生可以在短时间内查看数据。
