摘要
磁耦合线圈是水下无线感应耦合传输系统中的核心部分。该文从应用角度对水下无线感应耦合传输系统的磁耦合线圈参数展开分析与实验研究。首先通过耦合线圈的磁场强度、线圈尺寸、线圈匝数等理论分析评估线圈对通信质量的影响,其次通过多次实验对3种线圈匝数和3种不同的频率进行了参数分析和测试实验。分析结果得出在谐振点上的磁耦合强度最大,在耦合线圈尺寸固定时,频率为200kHz,匝数为20匝的线圈传输效果达到最佳。
Magnetic coupling coil is the core of the underwater wireless inductively coupled link transmission system.This paper states the analysis and experiment research of coil in an underwater wireless inductively coupled link transmission system from the application point of view.First,the evaluation influencing the communication quality are analyzed,which includes the magnetic intensity of coupling coil,coil size and coil turns.Then analyze the parameter,make many tests and experiments on the three kinds of coil turns and three different frequencies.Experiment results show that the intensity of magnetic coupling reaches to maximize on the point of resonance,and if the coil size is fixed,it has the best transmission result when frequency is 200KHz and coil turns is 20.
