  • PRIMARY NODE OF SEAFLOOR OBSERVATORY NETWORK BASED ON CONSTANT CURRENT POWER SUPPLY
    Publication number: 20210313798
    Abstract: A primary node of a seafloor observatory network based on constant current power supply is provided. The primary node is connected in series to a submarine cable of a backbone network. The primary node is connected to a shore station and an adjacent primary node by submarine cable terminal boxes, respectively. The primary node includes an underwater power supply and a communication control module. The underwater power supply is used for converting constant current power provided by the shore station into power for the primary node and some backup power, and outputting direct-current constant voltage power for the communication control module, and is further used for controlling the primary node to access and exit from the network. The communication control module is used for monitoring the internal state of the primary node by control system backup, and sending the state information and data to the shore station.
