地下和水下等极端环境中的物联网（IoT）是监测其中状态和开发资源的重要技术。使用有源 UHF 无线电的现有解决方案存在高功耗和高信号传播损耗，这增加了维护成本。本文介绍了一种使用无源传感器和近场通信 (NFC) 的低功耗物联网技术。回顾了现有的基于磁感应的 NFC 和其他通信协议，并确定了它们的优点和局限性。然后讨论了基于NFC的低功耗远程无源传感系统的系统框架、关键技术和研究挑战。该系统可以在各种非均匀的极端环境中实现无处不在的传感和计算。介绍了其在精准农业、道路基础设施监测和水质监测方面的应用。
The Internet of Things (IoT) in extreme environments, such as underground and underwater, is an essential technology to monitor the status and exploit resources therein. Existing solutions using active UHF radios experience high power consumption and high signal propagation losses, which increase the cost of maintenance. In this article, a low-power IoT technology using passive sensors and near field communication (NFC) is introduced. Existing magnetic induction-based NFC and other communication protocols are reviewed, and their advantages and limitations are identified. Then the system framework, key technologies, and research challenges of the low-power long-range NFC-based passive sensing system are discussed. This system can enable ubiquitous sensing and computing in various inhomogeneous extreme environments. Its applications in precision agriculture, road infrastructure monitoring, and water quality monitoring are presented.
