船舶轴功率测量是评估船舶推进系统工作状态的重要手段。传统的设备使用电池供电，但只能提供2-4小时的连续监测时间。针对这一问题，本文提出了一种基于磁共振的轴功率测量新技术。它能够在5至20毫米的距离内传输70 mA。我们通过实验证明了发射器中的自谐振线圈到接收端的有效功率传输，以实现能量的传输。结果表明，使用磁共振技术的应变型测量产生上级的结果，使用电池供电的测量，因此具有应用的重要性。
Marine shaft power measurement is believed to assess the working condition for marine propulsion system. The traditional equipment uses battery-powered supply but could provide only 2-4 hours continuous monitoring time. To address this issue, a new shaft power measurement technique based on magnetic resonances is proposed in this paper. It was able to transfer 70 mA over distances in the range of 5 to 20 millimeters. We experimentally demonstrated efficient power transfer over the self-resonant coils in the transmitter to the receiving end in order to achieve the transfer of energy. It is shown that the strain-type measurement using the magnetic resonances technique produces superior results to those using battery-powered measurements, and thus has application importance.
