Ship monitoring and managing system and method for submarine pipeline maintenance

Abstract

The invention discloses a ship monitoring and managing system and method for submarine pipeline maintenance. The system comprises a monitoring centre, an AIS (automatic identification system) base station, a patrol ship, a satellite communication link and an optical cable communication network, wherein the satellite communication link comprises a communication link between the Big Dipper satellite or maritime satellite and a satellite receiving station; the AIS base station receives the information of surrounding ships and transmits the information to the monitoring centre; the patrol ship is equipped with an AIS receiver and a satellite data emitter for monitoring surrounding ships and transmitting the monitored ship information back to the satellite receiving station through the satellite communication link; and the satellite receiving station transmits the data to the monitoring centre via an optical cable. A maritime optical cable / cable route is protected by applying the system or method provided by the invention. The monitoring centre can actively schedule patrol ships in time to drive away illegal ships or to guard in dangerous areas by macro-controlling general security of the maritime cable route.

Description

technical field [0001] The invention relates to ship monitoring and management, in particular to a ship monitoring and management system and method for submarine pipeline maintenance. Background technique [0002] Although the submarine cable equipment used to transmit information is laid several meters deep underground and in shallow seas and deep seabeds, it is also vulnerable to damage from mechanical equipment such as excavators and sailing fishing boats. China's submarine cables are blocked every year, causing economic losses of hundreds of millions of dollars. The repeated blockages were mainly caused by the operation of fishing boats. Among them, fishing boats with sails and nets are most likely to cause damage to submarine cables. In order to deal with this problem, while increasing the propaganda of the standardized operation of fishing boats, it is necessary to strengthen the effective supervision of the submarine cable sea area, realize real-time monitoring and ...

AI Technical Summary

Problems solved by technology

[0005] (1) Poor real-time performance

The monitoring center can only understand the distribution of illegal ships on the submarine cable route by summarizing and analyzing the data reported by patrol ships, and cannot monitor the illegal ships in real time

[0006] (2) Poor initiative

The only way for the monitoring center to know the safety status of the submarine cable route is through the report of the patrol ship. It is impossible to actively understand the specific situation of a certain area, and it is impossible to make reasonable dispatches to the patrol ship in the first place.

[0007] (3) The data lack comprehensiveness

Due to the limited number of patrol boats, only a small part of the entire protected area can be covered at the same time, so the information obtained on driving ships lacks completeness and comprehensiveness

[0008] (4) Poor data accuracy

Since the data of violating ships obtained by the monitoring center is obtained through SSB voice communication, the data obtained by the staff on board varies from person to person, and there are certain errors in the data obtained by the monitoring center

[0009] (5) No data management function

Since the monitoring center obtains the data through SSB voice communication with the patrol ship, the obtained data cannot be saved in real time, nor can the data be traced back
