Deep-sea and far-sea converged networking communication system

The invention relates to the field of communications, the invention discloses a deep-sea and far-sea converged networking communication system, and solves the problem that unsmooth communication in deep and far seas causes inconvenience to various kinds of work. According to the invention, the key point of the technical scheme is characterized in that the system comprises a command terminal, a transfer terminal and an individual terminal which are located on a communication node of a communication link; the command terminal communicates with the transfer terminal through a first-stage communication link, and the transfer terminal communicates with the individual terminal through a second-stage communication link, wherein the first-stage communication link and the second-stage communicationlink respectively comprise a plurality of communication modes; the transfer terminal is provided with a communication network selection module; the communication network selection module is used forrespectively selecting the most stable communication mode from the first-stage communication link and the second-stage communication link to form a complete communication link, so the most stable communication link is selected and formed from all the communication modes, the communication level of the deep sea and the far sea is improved, and the development of the deep sea and the far sea is facilitated.
