用于低功率飞行器传感器的RF无线功率传输的评估
Evaluation of RF Wireless Power Transfer for Low-Power Aircraft Sensors
摘要：
低功耗传感器可以集成到飞机中，用于许多用例。传统上，这些传感器通过电缆供电，这给飞行器的整体效率带来了各种缺点。或者，可以使用电池。然而，这意味着需要进行额外的维护以更换电池。移除电力电缆的另一种选择是使用射频（RF）无线电力传输（WPT）系统。尽管文献中已经研究了通用RF WPT技术，但其在航空用例中的可行性尚未得到充分研究。在本文中，我们研究的可行性RF WPT无线供电的低功耗在机舱传感器。在机舱模拟，我们表明，RF WPT技术是能够几乎完全覆盖20个座位的区域，并使用接收信号强度指标（高达$28$ mW）和数据包间隔率（高达$5.5$ Hz）进行定量评估。此外，我们在实验室环境中进行了多频正弦波功率传输方案的实验，从而提出了潜在的方法来提高接收器的灵敏度，从而增加WPT覆盖在机舱内，而不改变平均传输功率。总体结果表明，某些低功率客舱用例可以由现有的商用RF WPT系统支持。
英文摘要：
Low-power sensors can be integrated into an aircraft for numerous use cases. Conventionally, these sensors are powered via cables, which introduces various disadvantages to the overall efficiency of the aircraft. Alternatively, batteries may be used. However, this implies the necessity of additional maintenance for battery replacement. Another option to remove power cables is to use Radio Frequency (RF) Wireless Power Transfer (WPT) systems. Although general RF WPT technology has been studied in the literature, its feasibility for aviation use cases is not fully investigated. In this paper, we study the feasibility of RF WPT to wirelessly power low-power in-cabin sensors. In a cabin mock-up we show that RF WPT techonology is capable of almost fully covering an area of 20 seats and quantitatively assess this using Received Signal Strength Indicators (up to $28$ mW) and packet interval rate (up to $5.5$ Hz). Furthermore, we perform multi-tone sinusoidal wave experiments for power transmission scheme in a lab environment and thereby present potential ways to improve receiver sensitivity and consequently increase the WPT coverage in the cabin without changing the average transmission power. The overall results show that certain low-power cabin use cases can be supported by already existing commercial RF WPT systems.
