Ship or offshore mobile platform watertight equipment monitoring and fault diagnosis system

Abstract

The invention discloses a ship or offshore mobile platform watertight equipment monitoring and fault diagnosis system. The ship or offshore mobile platform watertight equipment monitoring and fault diagnosis system includes a watertight equipment monitoring local monitoring system, a ship industrial Ethernet and a bridge remote monitoring alarm diagnosis platform, wherein the watertight equipment monitoring local monitoring system is used for acquiring the state signals of watertight equipment so as to generate monitoring signals, carrying out fault diagnosis on the state signals so as to generate corresponding real-time monitoring signals, and generating corresponding pre-diagnosis information according to diagnosed non-real-time complex faults; the bridge remote monitoring alarm diagnosis platform is connected with the watertight equipment monitoring local monitoring system through the ship industrial Ethernet; the pre-diagnosis information is inputted into the bridge remote monitoring alarm diagnosis platform through the ship industrial Ethernet so as to be applied to final fault diagnosis; and when a fault occurs, shutdown control signals are emitted, so that maintenance information can be further obtained. With the ship or offshore mobile platform watertight equipment monitoring and fault diagnosis system of the invention adopted, two-stage fault diagnosis can be carried out on a whole ship and an offshore mobile platform, and comprehensive monitoring and operation maintenance of watertight integrity and the watertight equipment can be realized.

Description

technical field [0001] The invention belongs to the technical field of watertight equipment for ships or mobile offshore platforms, and in particular relates to a remote monitoring and fault diagnosis system for watertight equipment for ships or mobile offshore platforms. Background technique [0002] The watertight integrity of a ship refers to preventing seawater from intruding into the hull from external openings or openings on decks and bulkheads of ships and mobile offshore platforms (including but not limited to various semi-submersible and floating drilling storage and offloading platforms), while at the same time being able to The overall watertightness required to control the flow of submerged seawater within the hull. Watertight equipment is an important equipment to close the opening of watertight compartments and maintain watertight integrity. It can protect the ship from sinking or capsizing, or delay sinking or capsizing, and prolong the precious rescue time. ...

Problems solved by technology

However, limited by the controller system structure and programming method, the system does not have complex intelligent diagnosis capabilities, and it cannot perform complex fault diagnosis, such as complex faults such as equipment working overtime and abnormal hydraulic system parameters, and cannot give corresponding solutions. Maintenance solutions, resulting in the current monitoring system based on programmable logic controllers unable to meet the current needs of continuously improving monitoring and fault diagnosis of watertight equipment
