Method, system and computer-readable storage medium for breakage prevention and breakage detection for submarine optical cable

Abstract

This invention provides a method, system, and computer-readable storage medium for preventing and detecting submarine optical cable breaks. This invention can prevent cable breakage without increasing hardware construction costs and can integrate with transmission network monitoring systems, AIS, and radar intelligence to take preventative measures against vessels entering the submarine optical cable warning zone, preventing improper vessel operation from snagging the cable. If a core wire in the submarine optical cable breaks, the obstruction location can be quickly located using an OTDR (Optical Time Discharge Mapping) to find any non-obstructed hollow core wires available for backup. Then, cross-referencing AIS and radar intelligence data confirms whether the breakage was caused by a vessel. This invention can take preventative measures against vessels near submarine optical cables to avoid breakage, reduce OTDR lifespan wear, improve monitoring accuracy, and estimate the cause of the breakage.

Claims

1. A method for preventing and detecting breakage of submarine optical cables, comprising: Check whether both the service layer signal loss alarm and the control layer signal loss alarm are received simultaneously from the optical transmission equipment of the submarine optical cable core wire. If neither the service layer signal loss alarm nor the control layer signal loss alarm is received simultaneously, it is determined whether a vessel has entered the warning zone of the submarine optical cable. If a vessel has entered the warning zone, an alarm is issued to the user, and the user is advised to take appropriate measures. If both the service layer signal loss alarm and the control layer signal loss alarm are received simultaneously, it is determined that the core wire has been broken, and the user is notified of the breakage.

2. The method for preventing and detecting breakage of submarine optical cables as described in claim 1, wherein, The system determines whether a vessel has entered the warning zone based on the vessel's position provided by its Automatic Identification System (AIS).

3. The method for preventing and detecting breakage of submarine optical cables as described in claim 1, wherein, The location of radar echoes is used to determine whether any ships have entered the warning zone.

4. The method for preventing and detecting breakage of submarine optical cables as described in claim 1, wherein, If a vessel enters the warning zone and the vessel has activated its Automatic Identification System (AIS), the method for preventing and detecting the breakage of the submarine optical cable further includes: informing the user of the vessel's name, location, speed, and course provided by the AIS; and broadcasting a warning to the vessel through the AIS.

5. The method for preventing and detecting breakage of submarine optical cables as described in claim 1, wherein, If a vessel enters the warning zone, the method for preventing and detecting the breakage of the submarine optical cable shall include: monitoring whether the vessel remains in the warning zone and checking whether an alarm for a decrease in optical power quality of the submarine optical cable is received; and if the vessel remains in the warning zone and an alarm for a decrease in optical power quality is received, then an alarm shall be issued to the user again and it shall be recommended that the vessel be driven away.

6. The method for preventing and detecting breakage of submarine optical cables as described in claim 1, after determining that the core wire has experienced the breakage failure, further includes: The data transmitted by the core wire is switched to a core wire in the submarine optical cable or another submarine optical cable that has not yet been used to transmit data and has not experienced any breakage or obstruction.

7. The method for preventing and detecting breakage of submarine optical cables as described in claim 1, after determining that the core wire has experienced the breakage failure, further includes: Based on the vessel's movement trajectory provided by the vessel's Automatic Identification System, a suspicious vessel within a preset distance of the location of the broken obstacle is identified when the broken obstacle occurs, and the user is notified of the suspicious vessel.

8. The method for preventing and detecting breakage of submarine optical cables as described in claim 1, after determining that the core wire has experienced the breakage obstacle, further includes: Based on radar echo data within a preset time period prior to the occurrence of the fracture obstacle, a suspicious vessel located within a preset distance of the fracture obstacle within that preset time period is identified, and the user is notified of the suspicious vessel.

9. A computer-readable storage medium storing a plurality of instructions, which are read by an electronic device to execute a method for preventing and detecting breakage of a submarine optical cable as described in any one of claims 1 to 8.

10. A system for preventing and detecting breakage of submarine optical cables, comprising: Submarine optical cable, including the core wire; optical transmission equipment that interfaces with the core wire; The system also includes an integrated monitoring system for checking whether both service layer signal loss alarms and control layer signal loss alarms are received simultaneously from the optical transmission equipment. If neither service layer signal loss alarm nor control layer signal loss alarm is received simultaneously, the integrated monitoring system determines whether a vessel has entered the warning zone of the submarine optical cable. If a vessel has entered the warning zone, the integrated monitoring system issues an alarm to the user and suggests that the user take appropriate measures. Conversely, if the integrated monitoring system receives both service layer signal loss alarms and control layer signal loss alarms simultaneously, it determines that the core wire has broken and notifies the user of the breakage.
