This paper describes the design and realization of a wireless sensor gateway (WSG) within a wireless sensor network (WSN) for health monitoring. The WSN allows recording and wireless transmission of biosignals, namely the electrocardiogram, pulse wave and body weight, which are important parameters for cardiovascular monitoring. These can be displayed, analysed, and saved on the WSG through a user interface based on a touch screen. The proposed WSG has the distinctive feature of using two different radio transceivers, exploiting the advantages of each device. Currently, most personal computers and handhelds have standardized Bluetooth interfaces (IEEE 802.15.1) but not ZigBee interfaces (IEEE 802.15.4). Hence, the proposed gateway is designed to receive data from wireless sensors through its ZigBee interface and to forward them to a personal computer via its Bluetooth interface. This feature, combined with simple touch screen menu navigation will reach increased patient compliance and consequently increased benefit for patient in terms of healthcare and safety.
本文描述了用于健康监测的无线传感器网络（WSN）中无线传感器网关（WSG）的设计与实现。该无线传感器网络允许记录和无线传输生物信号，即心电图、脉搏波和体重，这些都是心血管监测的重要参数。通过基于触摸屏的用户界面，可以在无线传感器网关中显示、分析和保存这些参数。所提出的无线传感器网关具有使用两种不同无线电收发器的独特特性，充分利用了每种设备的优势。目前，大多数个人计算机和手持设备都有标准化的蓝牙接口（IEEE 802.15.1），但没有ZigBee接口（IEEE 802.15.4）。因此，所提出的网关设计为通过其ZigBee接口从无线传感器接收数据，并通过其蓝牙接口将数据转发到个人计算机。这一特性与简单的触摸屏菜单导航相结合，将提高患者的依从性，从而在医疗保健和安全方面为患者带来更大的益处。
