Underwater main base station of seabed observational network

Abstract

The invention relates to an underwater main base station of a seabed observational network. The underwater main base station comprises an anti-dragging network structure and a function unit. The anti-dragging network structure is of an integrated ellipsoidal face structure and is formed by connecting a protective cover assembly, a supporting framework assembly, a bottom supporting assembly and a bottom sealing assembly through bolts and nuts. The function unit is installed in the anti-dragging network structure and formed by connecting a submarine cable terminal assembly, a power unit assembly, a communication unit assembly, a submarine cable connection cathode assembly and a wet pluggable connector assembly through watertight connectors and watertight cables. The underwater main base station is connected to a bank base station through a standard single-electrode photoelectric composite communication submarine cable comprising a seabed relay and a seabed splitter. Negative high voltage single-electrode direct-current transmission with seawater as a current loop is adopted for communication with a wavelength division multiplexing optical fiber with a relay, and the reliability of the seabed observational network is improved through submarine cable segmental relay protection. The underwater main base station is simple in structure, compact in size, stable in arrangement and capable of reducing external force damage risks and reducing sediment deposition and further has the beneficial effects of being high in transmission efficiency, large in communication capacity and long in transmission distance.

Description

technical field

[0001] The invention belongs to the technical field of seabed observation, and relates to an underwater main base station of a seabed observation network, in particular to a negative high-voltage unipolar direct current transmission with an integral ellipsoidal surface anti-trawling structure, segmental protection and a wavelength division multiplexer with a relay. The underwater main base station of the submarine observation network using optical fiber communication. Background technique

[0002] The ocean accounts for more than 70% of the earth's surface, greatly affects the global environment and climate change, and contains huge energy and resources. It is the basis for human sustainable development. Therefore, understanding its operating mechanism is extremely important for the development of human civilization. To understand the ocean, it is necessary to carry out long-term real-time observation of the ocean, but its huge volume has seriously hindered h...
