针对目前电磁感应装定方式有效传输距离近、传输效率低等问题，基于电磁耦合谐振理论，提出了一种三线圈磁耦合共振装定信息传输系统，实现装定器和引信之间信息的快速、高效传输。利用互感耦合模型，分析得出了整个系统的接收电压比率与线圈谐振频率、耦合系数之间的关系，并根据该特点分析了基于频率调制的信息传输技术。实验结果表明，磁耦合共振装定系统可实现稳定、可靠的信息传递，性能可以满足大多数引信的设计要求，这种新颖的装定系统信息传输的实现，可为新一代武器系统的信息交联设计提供一定的理论支持。

In order to study on the transmission characteristics for wireless power system based on magnetic resonant coupling and research the relationship between transmission efficiency and coupling distance,the equivalent circuit model of wireless power transmission system via magnetic resonance coupling are analyzed based on the theory of two ports network analysis method. The condition that resonant frequency splitting phenomenon is produced,and a contact-less power transmission system was deduced,and the frequency expression of maximum efficiency is derived. The transmission characteristics of this system are researched using numerical simulation,and the law that two quite different resonant frequency turn into one until across the critical condition is revealed and resonant frequency is increased gradually with the coupling distance under the condition of optimum efficiency. Furthermore,the experiments’ results show that the transmission characteristics is consistent with theoretical analysis and simulation,and the analysis accurately describes the transmission characteristics of the power transfer system,and it will provide theoretical support for the magnetic resonant coupling system that work on the optimal frequency and has high efficient wireless power transmission.
