This article presents an atypical offline based LoRaWAN application for use in hospital settings, where the ability to maintain network connectivity during internet connection disruption is paramount. A prototype bed rail is demonstrated, providing advanced functionality compared to traditional bed rails. The manufactured prototype provides data to a nurses station reliably and operates under battery backup. The power consumption of the system under different transmission intervals was tested, allowing appropriate battery sizing for different applications to be specified accurately. It is expected that a single LoRaWAN gateway will be able to cover bed rails across an entire modern hospital, allowing minimal infrastructure cost to implement the device or application in a rapidly deployed field hospital.
本文提出了一种非典型的基于 LoRaWAN 的离线应用，适用于医院环境，在这种环境下，网络连接中断时保持网络连接的能力至关重要。展示了一种原型床轨，与传统床轨相比提供了更高级的功能。制造的原型可靠地向护士站提供数据，并在电池备份下运行。测试了不同传输间隔下系统的功耗，以便为不同应用指定准确的适当电池尺寸。预计单个 LoRaWAN 网关将能够覆盖整个现代医院的床轨，从而以最小的基础设施成本在快速部署的野战医院中实施该设备或应用。
