摘要
针对目前水下到水上跨介质数据传输过程中存在的问题,提出水下部分利用电流场在接收端形成感应电势差完成数据传输。采用有限元仿真水下极板电场通信系统在信号传输时电场的分布情况,通过改变信号频率,极板大小,电导率,介电常数,通信距离及接收端间距等参数,分析对信号传输产生的影响,得到了系统最佳接收间距模型,拟合出最佳接收间距计算公式并进行实验验证,为极板电场通信系统的设计及优化提供参考。
Aiming at the problems existing in the process of underwater to above-water cross dielectric data transmission,it is proposed that the underwater part uses the current field to form an induced potential difference at the receiving end to complete the data transmission.The finite element method is used to simulate the distribution of electric field of underwater plate electric field communication system during signal transmission.By changing the parameters such as signal frequency,plate size,conductivity,dielectric constant,communication distance and receiving end spacing,the influence on signal transmission is analyzed.The optimal receiving spacing model of the system is obtained,and the calculation formula of optimal receiving spacing is fitted and verified by experiments.It provides a reference for the design and optimization of plate electric field communication system.
