Submarine cable temperature monitoring system

Abstract

A submarine cable temperature monitoring system disclosed by the present invention comprises a temperature detection front-end device, a submarine cable temperature monitoring processing center and auser terminal. The temperature detection front-end device and more than one extracted redundant optical fiber in the submarine cable composite optical fibers are used as the temperature monitoring distributed sensors to connect, the temperature detection front-end device is communicated with the submarine cable temperature monitoring processing center and the user terminal separately, and the submarine cable temperature monitoring processing center comprises a server, a standard temperature test curve, a temperature monitoring mode recognizer, a submarine cable routing corridor graph, an alarmsystem, a database and a video monitor. The composite optical fibers in the photoelectric composite submarine cables are extracted to be used as the temperature monitoring distributed sensors and thetemperature change information transmission mediums, the special-purpose sensing and signal transmission optical fibers do not need to be laid, and the monitoring system is simple and practical, is convenient and rapid to implement, is small in investment and quick in effect, enables the investment of a submarine cable monitoring engineering to be reduced overall and substantially.

Description

technical field [0001] The invention relates to a temperature monitoring device, in particular to a submarine cable temperature monitoring system. Background technique [0002] With the rapid development of my country's social economy and the continuous deepening of marine development and utilization such as offshore wind power, the cross-sea transmission network continues to extend coverage to the coast and nearby islands at higher voltage levels, and submarine cables are more and more widely used. The submarine cable is an important channel for cross-sea power transmission. It is laid on the seabed. It has been eroded by sea water and washed by waves for a long time. Due to the special marine environment, it is impossible to monitor the temperature rise of submarine cables in real time and provide early warning, which may lead to greater accidents. [0003] Existing technical means cannot effectively monitor the temperature state of submarine cables. The technical method ...

Problems solved by technology

The submarine cable is an important channel for cross-sea power transmission. It is laid on the seabed. It has been eroded by sea water and washed by waves for a long time. Due to the special marine environment, it is impossible to monitor the temperature rise of submarine cables in real time and provide early warning, which may lead to greater accidents

[0003] Existing technical means cannot effectively monitor the temperature state of submarine cables. The technical method of using special sensors for power cable laying on land to monitor temperature has great technical difficulties, high investment costs, and poor reliability and effectiveness in the field of submarine cable monitoring.
