Aiming at the problems of limited communication modes,low reliability,weak scalability,and high power consumption existing in deep-sea submersible communication methods,this paper proposed a cross-domain relay buoy communication system design method based on multi-source communication links.Firstly,the composition,working principle,and working mode of the buoy communication system were introduced,and the system hardware design scheme with multiple communication methods and high scalability was described.Secondly,an optimal communication link selection strategy was proposed,which could dynamically select the optimal communication link according to the real-time status of each link,so as to improve the reliability and stability of system communication.Additionally,the data retransmission mechanism was introduced to effectively address the abnormal communication problems such as communication interruption and data packet loss,so as to ensure the accuracy and integrity of system communication.Finally,the system power management and power consumption optimization were designed,and a low-power control strategy was proposed to realize the refined management of system power supply and efficient low-power operation.Experimental results demonstrate that the design method of the buoy communication system proposed in this paper is effective and feasible,which can effectively solve the problems existing in the deep-sea submersible communication,achieve real-time data transmission over long distances,and provide technical support for improving the information transmission ability of underwater detection equipment.
