This paper presents a hybrid wearable sensor network system towards the Internet of Things (IoT) connected safety and health monitoring applications. The system is aimed at improving safety in the outdoor workplace. The proposed system consists of a wearable body area network (WBAN) to collect user data and a low-power wide-area network (LPWAN) to connect the WBAN with the Internet. The wearable sensors in the WBAN are exerted to measure the environmental conditions around the subject using a Safe Node and monitor the vital signs of the subject using a Health Node. A standalone local server (gateway), which can process the raw sensor signals, display the environmental and physiological data, and trigger an alert if any emergency circumstance is detected, is designed within the proposed network. To connect the gateway with the Internet, an IoT cloud server is implemented to provide more functionalities, such as web monitoring and mobile applications.
本文提出了一种混合可穿戴传感器网络系统,面向物联网 (IoT) 连接的安全和健康监测应用。该系统旨在提高户外工作场所的安全性。所提出的系统由一个可穿戴体域网 (WBAN) 组成,用于收集用户数据,以及一个低功耗广域网 (LPWAN) ,用于将 WBAN 与互联网连接。WBAN 中的可穿戴传感器用于使用安全节点测量主体周围的环境条件,并使用健康节点监测主体的生命体征。在提出的网络中设计了一个独立的本地服务器(网关),它可以处理原始传感器信号,显示环境和生理数据,并在检测到任何紧急情况时触发警报。为了将网关与互联网连接,实现了一个物联网云服务器,以提供更多功能,如网络监控和移动应用程序。
