A Constant Current Observation System for Underwater Cables Based on Observation Relay Platform

Abstract

The invention discloses an underwater cable constant-current observation system based on observation relay platforms. The underwater cable constant-flow observation system based on the observation relay platforms comprises a first bank base station for providing a high-voltage constant-current power supply, a second bank base station and a composite cable for connecting the first bank base stationwith the second bank base station and supplying electricity and communicating; N observation relay platforms are connected onto the composite cable at intervals; and each observation relay platform can utilize electric energy provided by a high-voltage conductor in the composite cable to monitor the environment data and can transmit the environment data to the first bank base station or the second bank base station through the composite cable to realize communication between undersea environment data and the outside. The system adopts constant-current power supply to effectively avoid attenuation of remote-distant transmission voltage, reduces the loss of the electric energy in the underwater cable, can effectively reduce the transmission voltage and improves the electricity efficiency; and by adoption of a mode of connecting the data relay unit with the relay in series, pavement of a long-distance observation chain can be realized on the premise of guaranteeing the reliability of theplatforms.

Description

technical field [0001] The invention belongs to the field of seabed monitoring, in particular to an underwater cable constant current observation system based on an observation relay platform. Background technique [0002] At present, with the depletion of land resources and the deterioration of water body environment, more and more underwater observation systems have emerged. A water body with a single environmental parameter is required. The tree-like observation system is bulky and the cascading relationship is complicated, which makes it more difficult to lay, and the idleness of redundant functions also increases the operating cost. [0003] The tree-shaped multi-node distribution method used in the existing underwater observation network has an obvious shortcoming. Once one of the tree-shaped nodes or the connected composite cable fails, the back-end cascaded nodes cannot work normally, which further Increased product reliability requirements and maintenance costs. ...
