Abstract

The invention discloses a fault diagnosis system for submarine observation network nodes, which comprises an energy fault diagnosis subsystem, a fault diagnosis subsystem inside a node cabin body, a fault diagnosis subsystem outside the node cabin body, a node main control circuit board and a shore station. The node main control circuit board is respectively connected with the energy fault diagnosis subsystem, the fault diagnosis subsystem inside the node cabin body and the fault diagnosis subsystem outside the node chain body, acquires running state detection signals, and is connected and communicated with the shore station. The fault diagnosis system for the submarine observation network nodes is specially designed for a submarine observation network node system, can finish conventional fault diagnosis and maintenance tasks of the submarine observation network nodes well, shortens the fault diagnosis time required by the submarine observation network nodes, ensures normal running of the submarine observation network nodes to the most extent, and greatly reduces the maintenance cost of the submarine observation network nodes.

Description

technical field [0001] The invention belongs to the technical field of deep-sea observation systems, and in particular relates to a fault diagnosis system for detecting and maintaining the operation status of seabed observation network nodes. Background technique [0002] The submarine observation network system can provide multi-element, multi-disciplinary long-term, comprehensive, and real-time observations, which can be applied to research fields including basic scientific research, resources and energy, exploration, development and utilization, disasters and environmental protection, navigation, etc., to meet the national The most basic requirements of seabed, water body and sea surface for marine safety. [0003] The node control system is the basic unit and core part of the submarine observation network. It is an automatic control electromechanical device based on the concentration, conversion and processing of underwater power and information. An interface device for...
