Main base station of submarine observation network based on constant-current power supply

Abstract

The invention discloses a main base station of submarine observation network based on a constant-current power supply. The main base station is connected in series in a backbone network submarine cable. The main base station is connected with a shore base station and an adjacent main base station through a submarine cable terminal box. The main base station comprises an underwater power supply anda communication control module. The underwater power supply is used for converting a constant-current power supply provided by a shore base station into a power supply of the main base station and aplurality of backup power supplies, outputting a direct-current constant-voltage power supply to the communication control module, and controlling the main base station to be networked and offline. The communication control module is used for monitoring the internal state of the main base station in a master control backup manner and sending the state information and data uploaded by the externalequipment to the shore base station. The communication control module is also used for receiving an instruction of the shore base station to perform fault isolation when the internal state has a fault. The main base station of submarine observation network based on the constant-current power supply has the advantages of high power and high reliability. The problems that a constant-voltage power supply type main base station is poor in submarine cable fault resistance and poor in robustness are solved.

Description

technical field [0001] The invention relates to the technical field of seabed observation network, in particular to a main base station of seabed observation network based on constant current power supply. Background technique [0002] Marine scientific research is undergoing a change from short-term observation of the sea surface to long-term continuous observation of the interior of the seabed. The seabed observation network is a new type of ocean observation method that utilizes seabed remote communication technology. Its realization is to connect up to shore-based power supply and communication equipment through submarine cables, submarine main base stations, repeaters and other equipment, and to connect downwards to various seabeds. Observation equipment realizes high-power continuous power supply to submarine observation equipment and real-time online acquisition of observation data. Submarine cables use traditional unipolar copper conductors and multi-core optical fi...

Problems solved by technology

[0007] In addition to the above design, in order to ensure the high reliability of the main base station, a design scheme for redundant backup of the main control and power supply is proposed, which solves the problem of low reliability when the main base station with single main control and single power supply works for a long time
