摘　　要：针对水下无线电能传输系统的数据采集与信息处理开展了系统研究。对于水下的无线电能传输系统,考虑到了复杂多变的水下环境对电能和信息传输产生一定程度的影响。海洋环境会受到温度、压力等一些环境因素的扰动,因此水下电能传输的介质具有不确定性,会对电能发送端和电能接收端的电磁场耦合产生影响,影响到水下无线电能传输的稳定性,导致海水中的无线电能传输系统的传输功率和传输效率发生改变。为此需要对水下的海洋环境信息进行实时采集,并分析对水下无线电能传输系统的电路参数和传输效率产生的影响。搭建了基于多种传感器的信息搜集与处理系统从而实现实时海洋数据采集,有效解决了水下数据的获取问题,提高了数据采集和数据处理效率。研究了海水的相对磁导率、电导率以及相对介电常数等系统信息和能量传输的影响规律,重点分析了温度和压力对无线电能传输的影响。The data acquisition and information processing of an underwater wireless power transfer(WPT)system are systematically studied in this paper.For this system,its transmission of power and information is affected to a certain degree considering the complex and changeable underwater environment.Since the marine environment is disturbed by some environmental factors such as temperature and pressure,the medium of underwater power transfer is uncertain,which will affect the electromagnetic field coupling between the power transmitting terminal and the power receiving terminal.As a result,the stability of underwater WPT will be affected,leading to changes in the transmission power and transmission efficiency of the WPT system under seawater conditions.Therefore,it is necessary to acquire the underwater marine environment information in real time and analyze the influences on circuit parameters and transmission efficiency of the underwater WPT system.An information acquisition and processing system based on a variety of sensors was built to realize real-time marine data acquisition,thus effectively solving the problem of underwater data acquisition and improving the data acquisition and data processing efficiency.The influences of the relative permeability,electrical conductivity,and relative permittivity of seawater on the system information and energy transfer are studied.In particular,the influences of temperature and pressure on WPT are analyzed in detail.
