基于磁共振的引信无线装定方法

摘要

针对电磁感应装定技术仅适合近距离(毫米级)应用的缺陷,为满足武器系统大距离条件下对能量和信息高效率、高质量同步传输的要求,提出基于磁共振的引信无线装定方法。该方法利用收发端线圈间的磁共振耦合实现能量的高效、大距离传输,根据磁共振系统能量传输性能特点,设计了基于间歇式能量调制及谐振调制的两种信息同步加载方式,并采用负载调制技术实现信息的反向传输。最后,基于该理论制作的原理样机在收发端线圈距离90 mm条件下,100μF储能电容可在20 ms时间充至12 V,信息双向传输正确可靠。实验结果表明,磁共振能量和信息无线同步传输理论正确,技术方案可行,可将磁共振技术应用于引信无线装定中。%The electromagnetic induction setting mode is only suitable for short distance (millimeter level)appli-cation.In order to meet the requirement of weapon systems for power and information efficiency and high-quali-ty synchronous transmission over large distance,a new setting method based on magnetic resonance was pro-posed.This method used magnetic resonance coupling between the coils of receiving and transmission terminals to achieve power efficient transfer over large distance.According to the performance of wireless power transmis-sion of magnetic resonance systems,two types of information synchronous loading methods based on intermit-tent power modulation and resonance modulation were designed,and information was reversely transferred by the technique of load modulation.With this principle,a prototype was designed.When the distance between the transmission and receiving terminals was 90 mm,the 100μF energy storage capacitor could be charged to 12 V in 20 ms,and information dual-direction transmission was accurate and reliable.Experiment results showed that the theory of wireless power and information synchronous transmission based on magnetic resonance proposed in this paper was correct,and the technical scheme was feasible.
