Description

Technical Field

[0001] The present application relates to the technical field of submarine cables, and particularly to a submarine cable reset system, method, device, computer equipment and storage medium. Background Art

[0002] With the development of submarine cable power transmission technology, submarine cables have been widely used in power supply for offshore platforms and islands, transmission of marine clean energy, and cross-regional power transmission. Due to the frequent number of fishery activities and the increase in marine engineering projects in recent years, submarine cables are easily damaged by human activities such as ship anchoring, dragging anchors, and pile driving, or natural disasters such as typhoons, resulting in the breakage of submarine cables and deviation from the original design route. Therefore, it is necessary to reset the repaired submarine cable to the original design route. The traditional method is to reset the submarine cable after repair by means of diver assistance or ship dragging. Diver reset is suitable for shallow waters and short distances, and it is difficult to carry out in deep waters with extremely low efficiency. For large-diameter cables, it is difficult to achieve due to their own tension and ocean current effects. The method of ship dragging is suitable for resetting long-distance submarine cables, but it is single-point stressed, and the submarine cable may be damaged during the dragging process, and only the endpoints can be guaranteed to return to the route, while the middle part of the submarine cable may be bent and deviate from the submarine cable route. Therefore, the traditional submarine cable reset technology has the problem of low reset accuracy. Summary of the Invention

[0053] As described in the background art, there is a problem in the prior art that the accuracy of submarine cable reset is relatively low. After research by the inventor, it is found that the reason for this problem is that with the development of submarine cable power transmission technology, submarine cables have been widely used in power supply for offshore platforms and islands, transmission of marine clean energy, and cross-regional power transmission. Due to the frequent number of fishing activities and the increase in marine engineering projects in recent years, submarine cables are easily damaged by human activities such as ship anchoring, dragging, and piling, or natural disasters such as typhoons, resulting in the breakage of submarine cables and deviation from the original designed route. Due to the continuous increase in submarine cables in recent years, the submarine cable routes are becoming increasingly competitive, and the submarine cable needs to be restored to the original designed route after repair. For the situation where the submarine cable is damaged and deviates from the route, after detecting the cable fault, if the deviated section of the cable can still be used, the traditional method is to use divers to assist in resetting or ship dragging to reset the submarine cable after repair. The diver reset is suitable for shallow waters and short distances, and it is difficult to carry out in deep waters, and the efficiency is extremely low. For large-diameter cables, it is difficult to achieve due to their own tension and ocean current effects; the ship dragging method is suitable for resetting long-distance submarine cables, but it is single-point stressed, and the submarine cable may be damaged during the dragging process, and only the endpoints can be guaranteed to be restored to the route, while the middle part of the submarine cable may be bent and deviated from the submarine cable route. If it cannot be effectively reset to the submarine cable route, it will affect the later submarine cable post-protection construction.

[0054] For the above reasons, the present invention provides a reset scheme for submarine cables, aiming to solve the problem of relatively low accuracy of submarine cable reset.

[0055] In one embodiment, as Figure 1 shown, a submarine cable reset system is provided, including:

[0056] A plurality of auxiliary ships 11, a plurality of positioning terminals 12, and a remote terminal 13.

[0057] Among them, the plurality of auxiliary ships 11 are respectively connected to the submarine cable and are used to assist the movement of the submarine cable; the positioning terminals 12 correspond to the auxiliary ships 11 one by one, and each positioning terminal 12 is arranged on the corresponding auxiliary ship 11 and is used to locate the position information of the submarine cable by determining the position information of each auxiliary ship 11; the remote terminal 13 is respectively wirelessly communicatively connected to each positioning terminal 12 and each auxiliary ship 11, and the wireless communication method can be a local area network or Bluetooth, etc., and is used to obtain the position information sent by each positioning terminal 12 and the preset submarine cable route, and based on each position information and the preset submarine cable route, determine at least one target auxiliary ship, and send a movement reset instruction to the target auxiliary ship; the movement reset instruction is used to instruct the target auxiliary ship to move to assist the submarine cable to be reset to the preset submarine cable route.

[0058] Among them, the preset submarine cable route can be the laying path of the submarine cable set according to various factors such as the working requirements of the submarine cable and the submarine geographical environment.

[0059] It can be understood that the positioning terminal 12 can be a GPS positioning device using GPS (Global Positioning System) positioning technology, which is a device that uses global positioning system technology to determine the position of an object. GPS calculates the longitude, latitude, and altitude of the device by receiving satellite signals from different positions, so as to accurately locate. In addition, other positioning technologies can also be used for the positioning technology, and no specific limitation is made here.

[0060] It should be noted that the submarine cable can be a submarine cable that needs to be reset after being salvaged to the water surface and repaired. After the faulty section of the submarine cable is confirmed, a diver or a salvage device salvages one end of the submarine cable to the water surface and fixes it to an auxiliary ship 11, and then uses a plurality of floating balls to tie along the submarine cable at a certain interval distance until all the floating balls are tied to the displaced section of the submarine cable. The length of the rope of the floating ball can be 1 / 2 of the water depth, so that the salvaged submarine cable can float smoothly on the water surface, avoiding dragging the submarine cable during the movement of the auxiliary ship 11 and causing damage to the cable. In addition, a plurality of auxiliary ships 11 are distributed beside the submarine cable at a certain interval distance, such as an equidistant interval of 100 meters or an unequal distance distribution method, and the submarine cable is fixed to each auxiliary ship 11.

[0061] In the above submarine cable reset system, it includes a plurality of auxiliary ships 11, a plurality of positioning terminals 12, and a remote terminal 13. Among them, the plurality of auxiliary ships 11 are respectively connected to a plurality of points of the submarine cable for assisting the movement of the submarine cable. The setting of the plurality of auxiliary ships 11 can assist in the movement at multiple points of the submarine cable, avoiding single-point dragging and thus causing damage to the submarine cable; the positioning terminal 12 corresponds to the auxiliary ship 11 one by one, and each positioning terminal 12 is arranged on the corresponding auxiliary ship 11 for determining the position information of each auxiliary ship 11 to locate the position information of the corresponding point of the submarine cable, thereby realizing the multi-section position monitoring of the submarine cable during the reset process; the remote terminal 13 is respectively wirelessly communicatively connected to each positioning terminal 12 and each auxiliary ship 11 for obtaining the position information and the preset submarine cable route sent by each positioning terminal 12, and based on each position information and the preset submarine cable route, determining at least one target auxiliary ship and sending a moving reset instruction to the target auxiliary ship; the moving reset instruction is used to instruct the target auxiliary ship to move to assist the submarine cable to be reset to the preset submarine cable route. By monitoring the position of the auxiliary ship 11 by the positioning terminal 12, the position of the submarine cable during the reset process is determined, and the movement of the auxiliary ship 11 is controlled according to the position of the submarine cable during the reset and the preset submarine cable route, helping the submarine cable to be reset to the preset submarine cable route and improving the accuracy of the reset.

[0062] In one embodiment, the remote terminal 13 is further configured to calculate the relative distance between each auxiliary ship 11 and the preset submarine cable route according to the position information of each auxiliary ship 11 and the preset submarine cable route, and determine at least one target auxiliary ship and the movement reset instruction of each target auxiliary ship based on each relative distance.

[0063] Wherein, the relative distance may be the vertical distance between the auxiliary ship 11 and the preset submarine cable route.

[0064] It can be understood that the remote terminal 13 determines the movement strategy for resetting the submarine cable according to the relative distance between the position information of the auxiliary ship 11 and the preset submarine cable route, so as to determine the target auxiliary ship that needs to move, and send the corresponding movement reset instruction to it. During the movement of the target auxiliary ship, the remote terminal 13 will also monitor the real-time position of the target auxiliary ship in real time, so as to move the submarine cable to above the preset submarine cable route more accurately, further improving the accuracy of resetting the submarine cable. When the relative distance between all the auxiliary ships 11 and the preset submarine cable route is 0 or lower than the preset threshold, the floating balls tied to the submarine cable are cut off, and the fixed connection between the auxiliary ship 11 and the submarine cable is released, so that the submarine cable slowly sinks to the seabed on the preset submarine route, thus achieving the reset effect.

[0065] In one embodiment, the remote terminal 13 is further configured to generate real-time image information from the position information of the auxiliary ship 11 and the preset submarine cable route, and display the real-time image information.

[0066] It can be understood that the remote terminal 13 generates a coordinate map of longitude and latitude, and the longitude and latitude of the position information of the auxiliary ship 11 are reflected in the coordinate map in the form of coordinate points. The preset submarine cable route can be reflected in the coordinate map in the form of a line, and is displayed through the display module of the remote terminal 13, as Figure 2 shown, providing a schematic diagram of the image information displayed by the remote terminal 13. It can enable the staff to intuitively see the position distribution of the auxiliary ship 11 to determine the actual position of the submarine cable, and can also assist the staff in making corresponding judgments and taking corresponding measures, such as issuing instructions in time when the auxiliary ship 11 yaws, etc.

[0067] In one embodiment, as Figure 3 shown, the auxiliary ship 11 includes:

[0068] A driving device 111, the driving device 111 is wirelessly communicatively connected to the remote terminal 13, and is configured to receive the movement reset instruction and drive the auxiliary ship 11 to move according to the movement reset instruction.

[0069] Among them, the driving device 111 may include a driving motor, a communication module, a processor, etc. The driving motor generally refers to an electric driving device used to push and maneuver the auxiliary ship 11. Different types of driving devices 111 can be adopted according to the design and use of the auxiliary ship 11, such as a DC motor, an AC motor, a synchronous motor, and a hybrid power system, etc.

[0070] In this embodiment, the mobile reset instruction is sent to the driving device 111 by means of wireless communication, which can realize the remote control of the auxiliary ship 11. In addition, by instructing the driving device 111 of the auxiliary ship 11 to execute the corresponding mobile operation through the mobile reset instruction, the accuracy of movement and the control efficiency can be improved, and further the reset accuracy of the submarine cable is improved.

[0071] In one embodiment, as Figure 4 shown, a method for resetting a submarine cable is provided, which is applied to the remote terminal of the submarine cable reset system described in the above embodiment. This method includes step S402 to step S406. Among them:

[0072] Step S402, obtain the position information of each auxiliary ship and the preset submarine cable route.

[0073] Among them, the auxiliary ship may be a ship used to assist the movement of the submarine cable.

[0074] Among them, the position information may include content such as the longitude and latitude, course, speed, timestamp, and vessel identification of the location where the auxiliary ship is located.

[0075] Among them, the submarine cable route refers to the specific laying path and network structure of the submarine optical cable or cable, and usually includes information such as the start and end positions of the submarine cable, the laying path, and the access nodes.

[0076] Optionally, the remote terminal receives in real time the position information of each auxiliary ship sent by the positioning terminal of each auxiliary ship to obtain the position of the submarine cable section connected to each auxiliary ship, and obtains the submarine cable route preset by the staff, providing a data basis for subsequent submarine cable reset.

[0077] Step S404, based on each position information and the preset submarine cable route, determine at least one target auxiliary ship and the mobile reset instruction for each target auxiliary ship.

[0078] Among them, the target auxiliary ship may be an auxiliary ship that needs to move to assist the movement of the submarine cable.

[0079] Optionally, the remote terminal determines the target auxiliary ship that needs to move to help reset the submarine cable to the preset submarine cable route based on the relative position and other content between each position information and the preset submarine cable route.

[0080] Step S406: Send a movement reset instruction to each target auxiliary vessel.

[0081] The movement reset instruction is used to instruct the target auxiliary vessel to move to assist in resetting the submarine cable to a preset submarine cable route. The movement reset instruction may include information such as the indicated movement speed, movement distance, and movement direction.

[0082] Optionally, the remote terminal sends a movement reset instruction corresponding to each target auxiliary vessel to each target auxiliary vessel, so that the target auxiliary vessel moves according to the movement reset instruction to gradually reset the submarine cable to the preset submarine cable route.

[0083] In this embodiment, by accurately obtaining the positions of each auxiliary vessel and the submarine cable section connected thereto, the accuracy of submarine cable reset is improved, the error during the reset process is reduced, and by analyzing the relative relationship between the position of the auxiliary vessel and the preset submarine cable route, the most suitable target auxiliary vessel for dragging can be scientifically determined, optimizing resource allocation. In addition, the system automatically generates movement reset instructions, reducing the need for manual monitoring and intervention, lowering the incidence of human errors, and improving the overall operation safety.

[0084] In one embodiment, the movement reset instruction includes a first movement instruction and a second movement instruction. Step S404 determines at least one target auxiliary vessel and the movement reset instruction for each target auxiliary vessel based on each position information and the preset submarine cable route, including:

[0085] According to each position information and the preset submarine cable route, determine the relative distance between each auxiliary vessel and the preset submarine cable route; take the auxiliary vessel corresponding to the minimum relative distance as the reference auxiliary vessel, and take the remaining auxiliary vessels as target auxiliary vessels; according to the relative distance of each target auxiliary vessel and the relative distance of the reference auxiliary vessel, determine the first movement instruction for each target auxiliary vessel; in the case where the relative distance of each target auxiliary vessel is equal to the relative distance of the reference auxiliary vessel, set the reference auxiliary vessel as the target auxiliary vessel and generate a second movement instruction for each target auxiliary vessel.

[0086] The first movement instruction is used to instruct the target auxiliary vessel to move until the relative distance of the target auxiliary vessel is equal to the relative distance of the reference auxiliary vessel.

[0087] Optionally, the remote terminal calculates the relative distance between each auxiliary ship and the preset submarine cable route according to each position information and the position information of the preset submarine cable route. It can be the vertical distance. The auxiliary ship corresponding to the minimum relative distance is used as the reference auxiliary ship, and the remaining auxiliary ships are used as target auxiliary ships. Taking the relative distance of the reference auxiliary ship as the standard, calculate the distance, moving direction, moving speed, etc. required for the relative distance of each target auxiliary ship to be reduced to the relative distance standard of the reference auxiliary ship, and generate the first movement instruction. It should be noted that the moving speeds of each target auxiliary ship need to consider the stress angle that the submarine cable can withstand and the ocean current speed on the sea surface where each target auxiliary ship is located, etc., to ensure that the submarine cable is not damaged during the multi-point force movement. Send the first movement instruction to each target auxiliary ship. When the remote terminal monitors that the relative distance of each target auxiliary ship is equal to the relative distance of the reference auxiliary ship, it indicates that all auxiliary ships are parallel to the preset submarine cable route. Set the reference auxiliary ship as the target auxiliary ship and generate the second movement instruction for each target auxiliary ship. The second movement instruction instructs all target auxiliary ships to move towards the preset submarine cable route in the direction of reducing the relative distance at the same speed, and finally realizes that the relative distance of all auxiliary ships is reduced to 0 or below the preset distance threshold, achieving the reset of the submarine cable. As Figure 5 shown, a schematic diagram of the image information after the reset of the submarine cable is provided.

[0088] In this embodiment, by calculating the relative distance between each auxiliary ship and the preset submarine cable route in real time, the reference auxiliary ship and the target auxiliary ships can be determined. The generated movement instruction is based on the distance standard of the reference auxiliary ship, which helps to ensure that all auxiliary ships have a unified goal and direction of movement, reducing errors. Through uniform and reasonable multi-point force movement, the excessive twisting and stretching of the submarine cable can be reduced, protecting its structural integrity. In addition, through the integrated work of the remote terminal, each ship can timely obtain the status of each other, realizing information sharing and rapid response.

[0089] In one embodiment, after step S402 obtains the position information of each auxiliary ship and the preset submarine cable route, it further includes:

[0090] Generate real-time image information from the position information of the auxiliary ship and the preset submarine cable route, and display the real-time image information.

[0091] Among them, the image information can be a two-dimensional coordinate image with longitude and latitude as the coordinate axes. Among them, the position information of the auxiliary ship is represented in the form of coordinate points, and the preset submarine cable route is represented in the form of a line.

[0092] Optionally, the remote terminal stores the position information of each auxiliary ship and the preset submarine cable route in the form of latitude and longitude points, obtains the converted latitude and longitude points of the auxiliary ship and the latitude and longitude points of the preset submarine cable route, integrates the above latitude and longitude point information into a unified dataset, and uses a preset visualization tool, such as a graphics library or software, to draw a nautical chart or an aerial view based on the integrated data. Through a timer or a data trigger mechanism, the position information of the auxiliary ship and the image of the submarine cable route are updated regularly, so as to obtain real-time image information, and the real-time image information is displayed through the display panel of the remote terminal.

[0093] In this embodiment, by generating real-time image information including the position information of the auxiliary ship and the preset submarine cable route, the relationship between the position information of the auxiliary ship and the submarine cable route can be displayed in a more intuitive way, which is convenient for the operator to understand. The clear visualization interface makes it easier for the operator to identify key problem areas, such as the situation where the auxiliary ship deviates from the submarine cable route, so as to make corresponding decisions quickly.

[0094] In one embodiment, another method for resetting a submarine cable is provided, which is applied to a submarine cable reset system and includes:

[0095] The submarine cable reset system includes: a faulty submarine cable, an auxiliary ship, a GPS positioning device (positioning terminal), a buoy, and a GPS integrated display device (remote terminal).

[0096] Step 1, after confirming the faulty section of the submarine cable, use divers or a salvage device to fish one end of the submarine cable onto the auxiliary ship, tie a buoy to the submarine cable every 5 meters with a rope whose length is 1 / 2 of the water depth, and the auxiliary ship slowly moves along the direction of the submarine cable to tie all the displaced sections of the submarine cable with buoys.

[0097] Step 2, use multiple auxiliary ships (one every 100 meters) to fix the submarine cable on the ships, and equip each ship with a high-precision GPS.

[0098] Step 3, import the submarine cable route into the GPS integrated display device, turn on the GPS on each auxiliary ship, and the current positions of each auxiliary ship and the distance from the position of the submarine cable route can be viewed in real time in the GPS integrated display device.

[0099] Step 4, the real-time vertical distance between each ship and the submarine cable can be displayed in real time through the GPS integrated display device. Taking the ship closest to the submarine cable (reference auxiliary ship) as a reference point, the ship farthest from the submarine cable moves vertically towards the submarine cable direction and stops after traveling to the same vertical distance as the reference point. The second farthest ship also moves vertically towards the submarine cable direction with this reference point and stops after traveling to the same vertical distance as the reference point. Other ships move in turn from far to near according to the real-time vertical distance from the submarine cable to make the connection line of all ships parallel to the submarine cable.

[0100] Step 5: All vessels move towards the submarine cable at the same speed (2 - 3 knots) until all vessels reach directly above the submarine cable.

[0101] Step 6: When all auxiliary vessels reach above the submarine cable route, cut the floats on the submarine cable to make the submarine cable slowly sink, thus achieving the effect of resetting the submarine cable. The GPS integrated display device can overlay the chart layer and mark the submarine cable route. When connected to the GPS, the positions of each GPS can be viewed in real time, and the distance from the submarine cable route can be visually displayed. Each auxiliary vessel can be monitored and commanded to move through this device.

[0102] In this embodiment, this method addresses the problems of low efficiency, low precision, and easy damage to the submarine cable in the methods of diver-assisted reset or ship towing after submarine cable repair. By using floats to first float the submarine cable into a suspended state, it facilitates the movement during the submarine cable reset process. With the use of multiple auxiliary vessels and GPS real-time positioning and monitoring technology, it efficiently and accurately commands the vessels to perform the submarine cable reset. This not only improves the reset precision but also protects the safety of the submarine cable. This method is not only applicable to the reset project after submarine cable repair but also can be applied to the precise laying or reset project after repair of other submarine optical cables and pipelines. It has a wide range of applications and many application scenarios.
