[0002] Submarine optical cables are crucial for connecting operators to land. They lie buried on the ocean floor, often spanning hundreds to thousands of kilometers. Failures and significant optical attenuation can occur due to impacts with hard objects on the seabed or erosion by marine organisms. Repairs require the deployment of large repair vessels. Related technologies use on-site estimates of step distances based on optical time domain reflectometer measurements taken in land-based equipment rooms, and multiple positioning and salvage operations are performed. Each repair often costs several million to tens of millions of yuan. The lack of an effective and rapid fault location method results in significant maintenance costs, labor, and time associated with optical cable repairs, making it difficult to guarantee the quality of service for broadband, base station services, and other services carried by the optical cable network.

[0017] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0018] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0019] An embodiment of a method for locating an optical cable fault is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0020] Figure 1 FIG. 1 is a flow chart of a method for locating an optical cable fault according to an embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0021] Step S102: When a fault is detected in the optical cable, a fault distance of the fault point in the optical cable is determined, wherein the fault distance is the distance between the detection point and the fault point.

[0022] It can be understood that when a fault is detected in the optical cable, the fault point is preliminarily located, and the straight-line distance between the fault point in the optical cable and the detection point is determined as the fault distance of the fault point.

[0023] Optionally, an optical time-domain reflectometer (OTDR) is used for detection. The OTDR is connected to the fiber core of the optical cable to provide feedback on the detected fault distance.

[0024] In an optional embodiment, when a fault is detected in the optical cable, determining the fault distance of the fault point in the optical cable includes: performing real-time detection on the optical cable to obtain a real-time detection curve of the optical cable; identifying the real-time detection curve to obtain an identification result; and determining the fault distance when the identification result is an optical cable fault state or a light attenuation step state.

[0025] It is understood that the optical cable is tested in real time to obtain a real-time test curve. The real-time test curve is then identified to obtain an identification result. If the identification result indicates a faulty optical cable or a light attenuation step, a fault is detected in the optical cable, and the fault distance is determined.

[0026] Step S104: determining target positioning information corresponding to the fault point based on the fault distance and a preset optical cable positioning model.

[0027] It is understandable that the method of using the fault distance (straight-line distance) in the optical cable for positioning is prone to relatively large deviations. This is because the optical cable generally has an inclination angle in the actual application location, and the straight-line distance is not the horizontal distance. It needs to be processed in combination with the preset optical cable positioning model to obtain highly accurate target positioning information.

[0028] In an optional embodiment, when multiple electronic inspection points for positioning the optical cable are set on the outside of the optical cable, the method further includes: obtaining the inspection point numbers and inspection point slopes corresponding to the multiple electronic inspection points, and the straight-line distance between any two adjacent inspection points among the multiple electronic inspection points; and determining the optical cable positioning model based on the inspection point numbers and inspection point slopes corresponding to the multiple electronic inspection points, and the straight-line distance between any two adjacent inspection points.

[0029] It can be understood that a plurality of electronic detection points for positioning the optical cable are set on the outside of the optical cable, and the plurality of electronic detection points are used to perform segmented positioning of the position status of the optical cable. Each electronic detection point corresponds to its own detection point number and detection point slope. The detection point slope is the slope of the optical cable at the electronic detection point, and then the detection point numbers and detection point slopes corresponding to the plurality of electronic detection points are obtained. Then, the straight-line distance between any two adjacent detection points among the plurality of electronic detection points is determined. It should be noted that, since the optical cable in actual application is not kept horizontally or vertically placed, there may be an inclination angle. Therefore, the straight-line distance between any two adjacent detection points is not equivalent to the horizontal distance or vertical distance between any two adjacent detection points when the optical cable has an inclination angle. Based on the detection point numbers and detection point slopes corresponding to the plurality of electronic detection points, and the straight-line distance between any two adjacent detection points, the optical cable positioning model is determined. Through the above processing, the optical cable is segmented and located based on the information obtained from multiple electronic detection points. Then, through the accumulation method, the positioning of the entire optical cable and each electronic detection point on the optical cable is obtained, and an optical cable positioning model is established, which is conducive to improving the accuracy and efficiency of fault location.

[0030] Optionally, the distances between any two adjacent detection points among the plurality of electronic detection points are equal, or form a certain mathematical relationship, such as a linear relationship.

[0031] Optionally, each of the aforementioned electronic detection points is equipped with an electronic compass (or electronic inclinometer) for positioning. Information acquired by each electronic compass is transmitted via an inductive information transmission device, with the information, including the number, being assigned to each step from one end of the optical cable to the other. The electronic compasses at each of the electronic detection points are used to measure and record the inclination or slope of the optical cable at which they are located. The electronic compasses can utilize micro-gravity or a sliding mechanism to determine positional information such as the bottom or side of the optical cable at which they are located.

[0032] It should be noted that the above straight-line distance is the distance between two adjacent detection points in the optical cable. Since light propagates along a straight line, the differential idea is used to regard the distance between the two adjacent detection points as a straight line and perform equivalent processing.

[0033] In an optional embodiment, the above-mentioned optical cable positioning model is determined based on the detection point numbers and detection point slopes respectively corresponding to the above-mentioned multiple electronic detection points, and the straight-line distance between any two adjacent detection points, including: obtaining the estimated position information corresponding to the above-mentioned multiple electronic detection points based on the detection point numbers and detection point slopes respectively corresponding to the above-mentioned multiple electronic detection points, and the straight-line distance between any two adjacent detection points; obtaining preset position correction information; using the above-mentioned position correction information, correcting the estimated position information corresponding to the above-mentioned multiple electronic detection points, to obtain the corrected estimated position information corresponding to the above-mentioned multiple electronic detection points; and determining the above-mentioned optical cable positioning model based on the corrected estimated position information corresponding to the above-mentioned multiple electronic detection points.

[0034] It can be understood that by segmenting the optical cable through multiple electronic detection points, the optical cable between each two adjacent detection points is considered as a section. Based on the detection point numbers corresponding to the multiple electronic detection points, the detection point slope, and the straight-line distance between any two adjacent detection points, the estimated position information corresponding to the multiple electronic detection points can be calculated, that is, the estimated position information of each section of the optical cable is obtained. Preset position correction information is obtained. Since the estimated position information obtained by calculation has an error between the calculated value and the actual value, the position correction information is used to correct the estimated position information corresponding to the multiple electronic detection points, and the corrected estimated position information corresponding to the multiple electronic detection points is obtained, which is conducive to making the corrected estimated position information more accurate. Based on the corrected estimated position information corresponding to the multiple electronic detection points, a highly accurate optical cable positioning model is obtained. Through the above processing, the position correction information is used to correct the error between the theoretical value and the actual value, which improves the accuracy of the optical cable positioning model and helps improve the efficiency of optical cable fault positioning.

[0035] Optionally, the estimated position information may be of multiple types, such as longitude and latitude coordinates.

[0036] In an optional embodiment, the above-mentioned acquisition of preset position correction information includes: determining a first detection point in the above-mentioned multiple electronic detections that is located in a predetermined sea area; measuring the above-mentioned first detection point to obtain the measured position information corresponding to the above-mentioned first detection point; obtaining the estimated position information corresponding to the above-mentioned first detection point; comparing the above-mentioned measured position information with the above-mentioned estimated position information to obtain the position correction information of the above-mentioned first detection point.

[0037] It is understandable that in order to obtain position correction information, actual measurements need to be carried out. However, since it is difficult to conduct verification measurements throughout the application location of the optical cable, for example, for submarine optical cables on the seabed, the conditions for on-site measurements are only available in shallow sea areas such as estuaries where measurements can be made. First, determine the first detection point in the predetermined sea area among multiple electronic detections, measure the first detection point, and obtain the measured position information corresponding to the first detection point. Then, obtain the estimated position information corresponding to the first detection point, compare the measured position information with the estimated position information, and obtain the position correction information of the first detection point. It should be noted that due to the actual situation where full-scale measurement and comparison are impossible, such as the lack of measurement conditions in the deep sea, the point-to-surface and local-to-whole method is adopted, and the position correction information corresponding to the multiple electronic detection points in the optical cable is corrected by the position correction information of the first detection point obtained, so as to facilitate the acquisition of position correction information and reduce the human and material investment in measurement.

[0038] Optionally, there are multiple ways to obtain the measured position information, for example, using a buoy or other method to test the latitude and longitude information of the corresponding sea surface, that is, the measured position information.

[0039] In an optional embodiment, the above-mentioned estimated position information corresponding to the multiple electronic detection points is obtained based on the detection point numbers corresponding to the multiple electronic detection points, the detection point slopes, and the straight-line distance between any two adjacent detection points, including: determining the horizontal distance in the horizontal direction and the vertical distance in the vertical direction between any two adjacent detection points based on the detection point slopes corresponding to the multiple electronic detection points and the straight-line distance between any two adjacent detection points; determining the point sequence between the multiple electronic detection points based on the detection point numbers corresponding to the multiple electronic detection points; and determining the estimated position information corresponding to the multiple electronic detection points based on the point sequence and the horizontal distance and vertical distance between any two adjacent detection points.

[0040] It can be understood that based on the slopes of the detection points corresponding to the multiple electronic detection points, the straight-line distance between any two adjacent detection points can be calculated through conventional mathematical methods such as trigonometric functions to determine the horizontal distance between any two adjacent detection points in the horizontal direction and the vertical distance in the vertical direction. Based on the detection point numbers corresponding to the multiple electronic detection points, the point order between the multiple electronic detection points is determined. Based on the point order, the horizontal distance and vertical distance between any two adjacent detection points can be calculated using methods such as accumulation to determine the estimated position information corresponding to the multiple electronic detection points. Through the above processing, the estimated position information corresponding to the multiple electronic detection points can be effectively and quickly calculated.

[0041] To facilitate understanding, let's take a specific example. For example, if we use an optical time domain reflectometer to measure the straight-line distance between any of the multiple electronic detection points and the previous detection point in the optical fiber, we can obtain the straight-line distance between each two adjacent detection points one by one. Let's denote the straight-line distance between each two adjacent electronic detection points as L. Using trigonometric functions, we can easily calculate that the horizontal distance between the i-th detection point and the previous detection point is L*COS(Ki), and the vertical distance is L*TAN(Ki). Here, Ki is the slope of the i-th detection point, COS is the cosine function, and TAN is the sine function.

[0042] In an optional embodiment, after determining the target positioning information corresponding to the above-mentioned fault point based on the above-mentioned fault distance and the preset optical cable positioning model, the above-mentioned method further includes: determining the maintenance displacement instruction based on the above-mentioned target positioning information and the preset geographic information system map; and sending the above-mentioned maintenance displacement instruction to the target maintenance terminal.

[0043] It is understood that based on the target positioning information and the preset GIS map, the maintenance displacement instruction is determined by utilizing the data resources in the GIS, and the maintenance displacement instruction is sent to the target maintenance terminal, which performs maintenance operations on the fault point of the optical cable.

[0044] Optionally, the target maintenance terminal may be of multiple types, for example, a maintenance robot.

[0045] Optionally, the geographic information system map is a GIS map (English name: Geographic Information System or Geo-Information system map).

[0046] Through the above steps S102 to S104, the purpose of improving the accuracy of fault point positioning can be achieved, and the technical effect of improving maintenance efficiency and saving manpower and material costs can be achieved, thereby solving the technical problem in the related technology that the accuracy of fault point positioning in the optical cable is not ideal, resulting in a large amount of manpower and material costs for maintenance and low maintenance efficiency.

[0047] Based on the above embodiments and optional embodiments, the present invention proposes an optional implementation mode: Figure 2 FIG. 1 is a schematic diagram of an optional optical cable fault location method provided according to an embodiment of the present invention. Figure 2As shown, the application scenario is submarine optical cables. The system for locating optical cable faults includes an optical time domain reflectometer, an electronic compass (or electronic slope meter), a modeler (software module or hardware device), a cloud platform, and a GIS map. Data from the optical cable detector is also used. Based on the slope and location information detected at each detection point on the electronic compass attached to the optical cable, slope calculation and big data modeling are used to accurately infer the latitude, longitude, and depth of the fault point / location of high optical attenuation, and then push this information to the user.

[0048] Figure 3 FIG. 1 is a modeling flow chart of an optional optical cable fault location method provided in an embodiment of the present invention. Figure 3 As shown, the following steps S302 to S308 are specifically described:

[0049] Step S302 involves conducting on-site measurements. A first detection point, set on the optical cable, is selected at an estuary or shallow waters that is easily accessible for measurement. The measured location information, such as longitude and latitude, of the first detection point is measured at the estuary (or shallow waters). For shallow waters, a buoy or other method can be used to measure the measured location information of the corresponding first detection point. The measured location information is compared with the estimated location information to obtain position correction information for the first detection point.

[0050] In step S304, a plurality of electronic detection points for positioning the optical cable are set on the outside of the optical cable, and the plurality of electronic detection points are used to perform segmented positioning of the position status of the optical cable. The electronic detection point feeds back the slope of the detection point on the bottom or top of the optical cable segment where it detects and the detection point number to the cloud platform. At the same time, micro-gravity or sliding devices are also used to determine the bottom or side of the optical cable where the electronic detection point is located, and the slope of the detection point on the bottom or top of the optical cable position is measured. The slopes (horizontal downward tilt angles, which can be positive or negative) measured by the plurality of electronic detection points are respectively recorded as K1, K2...Ki..., where i is the detection point number, and the detection point number and its number position information are fed back to the cloud platform.

[0051] Step S306 calculates the distance between the electronic detection point and the previous detection point. Based on the slopes of the detection points corresponding to the multiple electronic detection points and the straight-line distance between any two adjacent detection points, conventional trigonometric calculations and other mathematical methods can be used to determine the horizontal and vertical distances between any two adjacent detection points.

[0052] Figure 4 FIG. 1 is a schematic diagram of a point distance of an optional optical cable fault location method according to an embodiment of the present invention. Figure 4As shown, the optical cable between the two electronic detection points is equivalent to a straight line using the differential concept, and the solution is obtained using trigonometric functions. The straight-line distance between any of the above points and the previous detection point is measured in the optical fiber using an optical time domain reflectometer. In this way, the straight-line distance between each two adjacent detection points can be obtained one by one. Let the straight-line distance between each two adjacent electronic detection points be recorded as L. Using trigonometric functions for calculation, it is easy to obtain that the horizontal distance between the i-th detection point and the previous detection point is L*COS(Ki), and the vertical distance is L*TAN(Ki). Among them, Ki is the slope of the i-th detection point, COS is the cosine function, and TAN is the sine function.

[0053] In step S308, the modeler constructs a cable positioning model for the submarine cable. Based on the estimated position information for each electronic detection point, the midpoints between each detection point are used as partitions to construct a model of the overall submarine cable position. Using the position correction information, the estimated position information is corrected to produce the corrected cable positioning model.

[0054] Figure 5 This is a flowchart of an optional optical cable fault location method provided according to an embodiment of the present invention, which is specifically described by the following steps S502 to S506:

[0055] In step S502, the optical time domain reflectometer detects a significant optical attenuation step in the real-time monitoring curve of the optical cable. To facilitate big data matching, when an optical cable fault or a significant optical attenuation step occurs, the optical time domain reflectometer provides feedback on the distance to the fault point, thereby obtaining the fault distance.

[0056] In step S504, the fault distance is matched with the optical cable positioning model obtained in steps S302 to S308, and the cloud platform and GIS map are calculated to determine the target positioning information corresponding to the fault point, and the latitude, longitude and depth of the fault point are calculated.

[0057] Step S506: Push the target positioning information to the user via the GIS map, and control the maintenance robot to carry out salvage and repair work.

[0058] The above optional implementations achieve at least one of the following: Automatically infer fault points / nodes with significant optical attenuation through big data matching, saving manpower and material resources required for submarine cable positioning. Automatically push location points based on matching and modeling results. Compared to related technologies, this innovative approach utilizes an electronic compass (electronic slope meter) to locate multiple monitoring points on the optical cable, establishes an optical cable positioning model, integrates latitude and longitude information, and performs position correction, thereby accurately pushing the fault point location.
