A main base station of submarine observation network based on constant current power supply

Abstract

The invention discloses a main base station of a submarine observation network based on constant current power supply. The main base station is connected in series in the backbone network submarine cable; the main base station is respectively connected to the shore base station and the adjacent main base station through a submarine cable terminal box; The main base station includes: an underwater power supply and a communication control module; the underwater power supply is used to convert the constant current power supply provided by the shore base station into a power supply for the main base station and several backup power supplies, and output a DC constant voltage for the communication control module The power supply is also used to control the network access and off-network of the main base station; the communication control module is used to monitor the internal state of the main base station through the main control backup mode, and send the status information and the data uploaded by the external device to the shore base station; When the internal state fails, it receives instructions from the shore base station for fault isolation. The main base station of the constant current power supply type submarine observation network proposed by the present invention has the advantages of high power and high reliability, and avoids the problems of weak resistance to submarine cable faults and poor robustness of the constant voltage power supply type main base station.

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
