Title:
MAIN BASE STATION OF SEAFLOOR OBSERVATORY NETWORK BASED ON CONSTANT CURRENT POWER SUPPLY
Document Type and Number:
WIPO Patent Application WO/2020/147459
Kind Code:
A1
Abstract:
Disclosed in the present invention is a main base station of a seafloor observatory network based on constant current power supply. The main base station is connected in series to a submarine cable of a backbone network. The main base station is connected to a shore base station and an adjacent main base station by means of submarine cable terminal boxes, respectively. The main base station comprises an underwater power supply and a communication control module. The underwater power supply is used for converting constant current power provided by the shore base station into power for the main base station and some backup power, and outputting direct current constant-voltage power for the communication control module, and is further used for controlling the main base station to access and exit the network. The communication control module is used for monitoring the internal state of the main base station by means of main controller backup, and sending the state information and data uploaded by an external device to the shore base station. The communication control module is further used for receiving an instruction from the shore base station for fault isolation when a fault occurs in the internal state. The main base station of a seafloor observatory network based on constant current power supply proposed by the present invention has high power and high reliability, and avoids problems in a constant voltage power supply type base station of poor resistance to submarine cable faults and poor robustness.
