物联网中的移动能量传输
Mobile Energy Transfer in Internet of Things
摘要：
物联网（IoT）通过连接各种电子设备为智慧城市提供动力。物联网设备的电源问题构成了当前物联网发展的主要挑战，因为电池续航能力差以及电缆部署麻烦。无线功率传输（WPT）技术最近已经成为一种有前途的解决方案。然而，现有的WPT进步无法支持像Wi-Fi通信那样的免费和移动充电。为此，提出了移动能量传输（MET）的概念，该概念主要依赖于谐振束充电（RBC）技术。自适应（A）RBC技术建立在RBC的基础上，但旨在通过以设备优选的电流和电压水平自适应地对设备充电来提高充电效率。提出了一种基于自适应源功率控制的移动ARBC方案。使用1，000 mAh锂离子电池进行的大量数值模拟表明，移动ARBC在节能方面优于简单的充电方案，例如恒定功率充电，轮廓自适应充电和距离自适应充电。
英文摘要：
Internet of things (IoT) is powering up smart cities by connecting all kinds of electronic devices. The power supply problem of IoT devices constitutes a major challenge in current IoT development, due to the poor battery endurance as well as the troublesome cable deployment. The wireless power transfer (WPT) technology has recently emerged as a promising solution. Yet, existing WPT advances cannot support free and mobile charging like Wi-Fi communications. To this end, the concept of mobile energy transfer (MET) is proposed, which relies critically on an resonant beam charging (RBC) technology. The adaptive (A) RBC technology builds on RBC, but aims at improving the charging efficiency by charging devices at device preferred current and voltage levels adaptively. A mobile ARBC scheme is developed relying on an adaptive source power control. Extensive numerical simulations using a 1,000mAh Li-ion battery show that the mobile ARBC outperforms simple charging schemes such as the constant power charging, the profile-adaptive charging, and the distance-adaptive charging in saving energy.
