Abstract

We report the experimental implementation of optically-powered wireless sensor nodes based on the power-over-fiber (PoF) technology, aiming at Industrial Internet of Things (IIoT) applications. This technique employs optical fibers to transmit power and is proposed as a solution to address the hazardous industrial environment challenges, e.g., electromagnetic interference and extreme temperatures. The proposed approach enables two different IIoT scenarios, in which wireless transmitter (TX) and receiver (RX) nodes are powered by a PoF system, enabling local and remote temperature data monitoring, with the purpose of achieving an intelligent and reliable process management in industrial production lines. In addition, the system performance is investigated as a function of the delivered electrical power and power transmission efficiency (PTE), which is the primary performance metric of a PoF system. We report 1.4 W electrical power deliver with PTE = 24%. Furthermore, we carry out a voltage stability analysis, demonstrating that the PoF system is capable of delivering stable voltage to a wide range of applications. Finally, we present a comparison of temperature measurements between the proposed approach and a conventional industrial programmable logic controller (PLC). The obtained results demonstrate that PoF might be considered as a potential technology to power and enhance the energy efficiency of IIoT sensing systems.

摘要

我们报告了基于光纤供电（PoF）技术的光供电无线传感器节点的实验实现，目标是用于工业物联网（IIoT）应用。该技术利用光纤来传输电力，并被提议作为解决危险工业环境挑战的一种方案，例如电磁干扰和极端温度。所提出的方法实现了两种不同的工业物联网场景，其中无线发射器（TX）和接收器（RX）节点由一个PoF系统供电，实现本地和远程温度数据监测，目的是在工业生产线上实现智能且可靠的过程管理。此外，研究了系统性能与所输送电功率和功率传输效率（PTE）的函数关系，功率传输效率是PoF系统的主要性能指标。我们报告了在功率传输效率为24%时输送1.4W电功率的情况。此外，我们进行了电压稳定性分析，证明PoF系统能够为广泛的应用提供稳定电压。最后，我们对所提出的方法与传统工业可编程逻辑控制器（PLC）之间的温度测量进行了比较。获得的结果表明，PoF可被视为为工业物联网传感系统供电并提高其能源效率的一种潜在技术。
