磁耦合谐振式无线能量传输技术是一种新型的电能传输技术,具有传输效率高、传输距离远的优点.对这种传输技术的基本原理进行了研究,提出利用该技术向安装在旋转部件上的嵌入式监控系统无线输送能量.设计了一对一的能量传输系统,并在此基础上研究了一对多的能量传输模式,分析了一对多的传输机理,实验中将多个接收线圈上的LED点亮.在接收线圈为简单线圈的方向性实验中,当接收线圈与发射线圈平行时,接收线圈接收到的能量最大,而当两者垂直时,接收线圈将接收不到能量.将接收线圈设计成2组圆线圈正交和3组圆线圈正交的形式,保证始终有磁感线穿过接收线圈,提高接收效果,实验验证了这种方法的有效性.

Wireless energy transmission based on coupled magnetic resonances is a new energy transmission technology,which has the advantage of high transmission efficiency and long transfer distance.According to researching the basic principles,transmitting energy to embedded monitor system installed in rotating parts was proposed.A one-to-one energy transfer system was designed.On this basis one-to-many transfer principle was researched and analyzed and multiple LED lights on the receiving coils could be lighted in the experiment.For the simple receiving coil was directional,the receiving energy had a maximum when the receiving coil was paralleled with the transmitting coil.And there was no receiving energy when the two coils were vertical.Therefore improving the structure of receiving part,that two or three group circular coils were orthogonal,ensured there was always the magnetotactic line through receiving coil.The experiment results show that the receiving energy is obviously improved.
