A photoelectric sensor smart submarine cable

Abstract

The invention relates to an intelligent photoelectric sensing submarine cable. The intelligent photoelectric sensing submarine cable comprises a cable body and one or a plurality of sensor nodes arranged on the cable body, and is characterized in that each sensor node comprises a voltage-resistant shell and a sensor arranged in the voltage-resistant shell; a core of the cable body is provided with photoelectric connectors in the shells of the sensor nodes; and the voltage-resistant shell of each sensor node is connected with the cable body through a mechanical connecting component. In a cable manufacturing process of a submarine cable factory, missions are deployed according to the submarine cable; and various sensor nodes which are designed and used according to the missions are integrated in the submarine cable as needed by a distance stipulated in the design. The intelligent photoelectric sensing submarine cable has functions of optical fiber communication, information transmission, remote power supplying, information sensing, self health condition detection and remote intelligent controlling.

Description

technical field [0001] The invention relates to a photoelectric composite submarine cable, in particular to a photoelectric composite submarine cable which has sensors and can be connected to external sensors. Background technique [0002] General composite submarine cables have disadvantages such as weak scalability, poor multi-task adaptability, weak deployability, and difficulty in maintenance. The cost performance of engineering applications is very low, and there is no innovation in itself. There is no maintenance management mechanism and appropriate design redundancy, and the maintenance engineering cost after the submarine cable is deployed is very high. [0003] Ordinary composite submarine cables do not have good scalability. Submarine cables generally include optical core wires, shielding layers, insulating layers, sheaths, and armor layers arranged from the inside to the outside. If it is necessary to integrate various sensors in the cable body according to the n...

AI Technical Summary

Problems solved by technology

If it is necessary to integrate various sensors in the cable body according to the task requirements, such as sound sensor, pressure sensor, torque sensor, tension sensor, temperature sensor, chemical sensor, magnetic sensor, vibration sensor, three-axis attitude sensor, three-axis orientation sensor, three-axis For underwater detection of various functional sensors such as axial inertial navigation sensors, the submarine cable needs to be processed on-site. The processing accuracy is low, the reliability and sealing performance cannot be guaranteed, and it is easy to be damaged after being deployed on the seabed.

Moreover, after the submarine cable is laid, if it is necessary to repair or add new sensors, it is almost impossible with the existing submarine cable technology
