英文摘要： The issues of transmission distance, transmission speed and supplication scope of the inductively coupled transmission technology in marine environmental monitoring will be further studied in the project. Based on the signal transmission theory, focus on three key issues: application environment, communication distance, transmission speed, with the methods of modeling and software simulation binding experiments, the characteristics of channel constituted by transmission cable, magnetic ring and water environment will be especially studied. Multi-conductor transmission channel model will be built to reveal the effects of channel structure and working mode on transmission reliability. On the basis of the above work, solutions to reliable, high-speed, real-time transmission will be presented with the optimal parameters, and the inductively coupled transmission system, which is applied for a variety of aquatic environment, long-distance, and high-speed transmission, will be designed. It will greatly improve the reliability and application scope of underwater data transmission to carry out this research, provide theoretical and experimental support and experiences to resolving the problem of far-reaching ocean data monitoring and real-time transmission, have important implications for the construction of marine environmentally stereoscopic observation network in china.
