摘要
水下传感网络是海洋开发利用的有效技术手段。然而,如何给位于水深的设备进行供电是部署水下传感网络的难题。为此,对如何给水下传感网络中的设备充电进行研究,旨在利用超声波给设备进行充电。首先,阐述从超声波提取电能的平台结构,再分析了如何将平台与水下数据通信单元相连。并利用一系列超级电容存储能量。通过实验证实,这些超级电容所存储的能量足够维持水下传感节点感测操作和超声波通信所需的能量消耗。
Internet of underwater things(IoUT)can provide new ways for the development and utilization of the ocean.Powering of these systems in deep water still remains one of the main challenges.Therefore,how to charge devices in the underwater sensor network.The goal of research is that underwater sensor node can be wirelessly recharged through ultrasonic waves.Firstly,the architecture of an underwater platform capable of extracting electrical energy from ultrasonic waves is introduced.We then illustrate how to interface this system with an underwater digital communication unit.The storage unit is realized with a batch of supercapacitors.We show through experiments that the harvested energy stored in the supercapacitors is sufficient to provide an underwater sensor node with the power necessary to perform a sensing operation and power an acoustic modem for ultrasonic communications.
