Problems solved by technology

Submarine cables and submarine optical cables in the suspended section are swayed under the action of ocean currents. After long-term accumulation, the support points at both ends are very easy to be worn, and failures may occur at any time
[0003] The existing technology can only deal with the accident after the accident, and it is impossible to find the hidden danger of failure without affecting the normal power transmission or optical fiber communication. existing problems

Embodiment 1

[0027] refer to figure 1 ,, figure 1 Severe diagram of a seaside wear detection device in the present invention. like figure 1 Show, a type of tunnel grinding hidden danger detection device includes: incentive source 1. Armor layer 2. Output cable 3. Overwriting optical fiber 4. Connecting optical fiber 5, POTDR device 6.

[0028] Among them, the incentive source 1 is connected to the armor layer 2 of the submarine cable through the output cable 3 to inject the current through the incentive source 1 of the armor layer 2. The connection of optical fiber 5 is connected with the seas cable to be used to monitor the change of fiber polarization changes.

[0029] It should be noted that the armor layer 2 is the outermost layer of the seaside cable. It is used to protect the cables from being damaged by external mechanical forces. It can prevent corruption and improve the ability to pull the tensile. Essence

[0030] Specifically, the wear of the seaside cable starts from the armor laye...

Embodiment 2

[0051] The present invention provides a method of testing the hidden dangers of waters image 3 ,, image 3 Severe the process of detection method for the hidden dangers of the seaside cable. like image 3 It is shown, and the detection method of another hidden dangers of the sea cables includes:

[0052] Step 301, open the road at both ends of the armor of the sea cable, connect the output cable on the incentive source 1 with the armor layer 2 to ensure that the current 1 pair of armor layer 2 is used for current 2 for the current. Incentive, the frequency of setting current incentive is F 0 ; Potdr device 6 connects to Optical Fiber 4 through connecting optical fiber 5 to monitor the polarized change of light transmission of light transmission along the optical fiber 4.

[0053] In this step, the armor layer 2 of the sea cable opens the road at both ends, and the output cable on the incentive source 1 is connected to the armor layer 2 to ensure that the incentive source 1 pair of a...

Embodiment 3

[0076] The present invention provides a type of hidden danger detection device for waters Figure 5 ,, Figure 5 In order to schematic diagram of the detection device of the hidden danger of the sea cable. like Figure 5 The test device 50 of the hidden dangers of the seal cable includes: fiber fiber module 501, incentive module 502, and detection module 503.

[0077] The optical fiber module 501 is used in the fiber of fiber in the seaside cable, or the fiber is attached to the sea cable.

[0078] The incentive module 502 is used to incentive current injecting a certain frequency into the fiber module 501.

[0079] The detection module 503 is used to detect and obtain signals on the fiber polarization changes.

[0080] Optional, monitor and obtain signals on the change of fiber polarizing state, including starting the POTDR device to obtain the first signal of the fiber module 501;

[0081] Start the incentive current of the incentive module 502 to generate an incentive current, the t...

Abstract

The invention discloses a submarine cable wear hidden danger detection device and method, and the device is characterized in that the device comprises an excitation source, an armor layer, an output cable, a coated optical fiber, a connection optical fiber, and POTDR equipment; the excitation source is connected with an armor layer of the submarine cable through an output cable and is used for injecting current into the armor layer through the excitation source, and the POTDR equipment is connected with a cladding optical fiber of the submarine cable through a connecting optical fiber and is used for monitoring the polarization state change of the optical fiber and positioning the accurate position of a damaged point according to the sudden change position of the polarization state change of the optical fiber. According to the invention, early warning can be carried out on defect hidden dangers before an accident occurs, and operation and maintenance personnel are reminded to handle the hidden dangers in time.

Description

Technical field [0001] The present invention involves the technology of searching and positioning of waters cable defects, and especially involves a tester and method and method of hidden dangers of seaside wear. Background technique [0002] Submarine Cable is divided into submarine cables and submarine optical cables. It is a wire wrapped in insulating material. It is laid on the bottom of the sea and underwater water for telecommunications transmission. The submarine cables and submarine optical cables are widely used in the fields of Internet, power transmission, wind power and other fields. Essence The sea cable has been on the bottom for a long time during the operation. Because of the uneven bottom of the sea, the phenomenon of suspended phenomena is prone to occur under the long -term discharge of the sea flow. The suspended section of the submarine cable and the submarine optical cable are swinging in the influence of the current. The support points of the two ends under...
