[0030] Figure 1 A flowchart of an optical cable fault location method provided by an embodiment of the present invention. This embodiment is applicable to the situation of locating the fault point of an optical cable. This method can be executed by an optical cable fault location device, and the optical cable fault location device can be implemented in the form of hardware and / or software. The optical cable fault location device can be configured in an electronic device such as a computer. As Figure 1 shown, the method includes:

[0031] S110. Obtain the coordinates of the optical cable laying nodes and the lengths of the optical cables between adjacent optical cable laying nodes according to the optical cable laying route.

[0032] Specifically, the optical cable laying route refers to the specific laying path of the optical cable on the ground or underground, usually including the starting point, the ending point, and the distribution points, etc. The optical cable laying route determines the layout and connection method of the optical cable. The optical cable laying node refers to a specific node on the optical cable laying route, and each optical cable laying node has corresponding coordinates. The coordinates refer to the numerical values used to represent the specific position of the optical cable laying node on a map or in a three-dimensional space. In the embodiments of the present invention, longitude and latitude are used to locate the optical cable laying nodes. The adjacent optical cable laying nodes refer to the directly connected optical cable nodes in the optical cable laying route. The length of the optical cable between adjacent optical cable laying nodes refers to the actual laying distance of the optical cable connecting two adjacent optical cable laying nodes.

[0033] In the embodiments of the present invention, obtaining the coordinates of the optical cable laying nodes and the length of the optical cable between adjacent nodes can provide necessary geographical information for subsequent fault detection, thereby reducing the cost of fault location.

[0034] S120. Determine a virtual optical cable route according to the coordinates of the optical cable laying nodes and the length of the optical cable between adjacent optical cable laying nodes.

[0035] Specifically, the virtual optical cable route refers to a theoretically formed optical cable connection path obtained by calculation and modeling using the coordinates of the optical cable laying nodes and the length of the optical cable between adjacent nodes, which can reflect the logical structure of the optical cable network.

[0036] In the embodiments of the present invention, the virtual optical cable route does not correspond to the actually laid optical cable route, but is a reference route generated based on the existing data. The virtual optical cable route can provide a position reference for the fault detection of the optical cable, helping to quickly locate the fault point and formulate a maintenance plan.

[0037] S130. Conduct fault detection on the optical cables in the optical cable laying route, and determine the distance from the fault point of the faulty optical cable to the detection point.

[0038] Specifically, the optical cable refers to a cable composed of multiple optical fibers, which is used for transmitting optical signals. The optical cable has the advantages of high bandwidth, low loss, and anti-interference, etc., and is usually used in communication networks, such as the power 4G wireless private network. The faulty optical cable refers to the optical cable in the optical cable network whose signal transmission is interrupted or the performance is degraded due to physical damage, poor connection, or other reasons. The optical cable fault will affect the communication quality, and in severe cases, data loss will also occur. The fault point refers to the specific position or section where the fault occurs. The detection point refers to a specific position set in the optical cable network for monitoring the status and performance of the optical cable.

[0039] Exemplarily, an optical time domain reflectometer can be used to detect the faulty optical cable. The specific steps are as follows: The optical time domain reflectometer emits short optical pulses into the optical cable, and these optical pulses propagate along the optical cable. When a fault occurs in the optical cable, part of the optical signal at the fault point will be reflected back to the optical time domain reflectometer. Based on the intensity and arrival time of the reflected signal, the optical time domain reflectometer can determine the distance from the fault point to the detection point and generate a reflection diagram.

[0040] In the embodiment of the present invention, determining the distance from the fault point to the detection point can reduce the time and labor costs required for fault troubleshooting and provide a data basis for subsequent positioning of the fault point.

[0041] S140. Determine the position of the fault point in the virtual optical cable route according to the distance from the fault point of the faulty optical cable to the detection point.

[0042] Specifically, the virtual optical cable route is a theoretical path established based on the coordinates of the optical cable laying nodes and the length of the optical cable between adjacent optical cable laying nodes. On this path, the distances between the nodes are known. Starting from the detection point and advancing along the virtual optical cable route, the position of the fault point can be deduced forward according to the known distance from the fault point to the detection point.

[0043] In the embodiment of the present invention, determining the position of the fault point in the virtual optical cable route reduces the blindness of fault finding, improves the efficiency of maintenance work, and thus ensures the rapid restoration of the optical cable.

[0044] The technical solution of the embodiment of the present invention realizes the positioning of the fault point of the faulty optical cable by measuring the distance from the fault point of the optical cable to the detection point and establishing a virtual optical cable route, and solves the problem of inaccurate positioning of optical cable faults in the prior art. The present invention can quickly and accurately determine the position of the fault point of the faulty optical cable, thereby greatly shortening the time for fault troubleshooting and repair, and effectively improving the accuracy, reliability and efficiency of optical cable fault positioning.

[0045] Figure 2 It is a flowchart of another optical cable fault positioning method provided by the embodiment of the present invention. On the basis of the above embodiments, optionally, S110. Obtain the coordinates of the optical cable laying nodes and the length of the optical cable between adjacent optical cable laying nodes according to the optical cable laying route, and S120. Determine the virtual optical cable route according to the coordinates of the optical cable laying nodes and the length of the optical cable between adjacent optical cable laying nodes can be further refined, such as Figure 2 As shown, the method includes:

[0046] S210. Number the optical cables in the optical cable laying route.

[0047] Exemplarily, the optical cables that need to be repaired in the optical cable laying route can be numbered using the letter G, and can be marked as G1, G2, G3... Gn at one time.

[0048] In the embodiments of the present invention, numbering the optical cables can achieve unified management of the optical cables, which is beneficial to quickly and accurately locate the faulty optical cables when they are found.

[0049] S220. Sequentially divide the numbered optical cables into optical cable laying nodes.

[0050] Exemplarily, select an optical cable to be detected. Starting from the starting point of the optical cable, select 5 - 10 meters as an optical cable laying node until the end point of the optical cable. The density of the optical cable laying nodes is related to the maintenance requirements and geographical environment. Areas that require frequent maintenance and areas with complex terrain or changing environmental conditions may require more optical cable laying nodes.

[0051] In the embodiments of the present invention, dividing the optical cable laying nodes can clearly define the structure of the optical cable network and provide a data basis for generating virtual optical cable routes subsequently.

[0052] S230. Determine the coordinates of each optical cable laying node and the length of the optical cable between adjacent optical cable laying nodes.

[0053] In the embodiments of the present invention, by determining the coordinates of each optical cable laying node and the length of the optical cable between adjacent optical cable laying nodes, a detailed model of the optical cable network can be established, providing important data support for subsequent management, maintenance, and fault detection. In addition, on the same optical cable, the coordinates of the optical cable laying nodes can also be marked as P1, P2...P3 respectively, and the lengths of the optical cables between adjacent optical cable laying nodes can be marked as L1, L2...L3 respectively.

[0054] S240. Correlate the coordinates of the optical cable laying nodes with the lengths of the optical cables between adjacent optical cable laying nodes.

[0055] Exemplarily, taking the wire numbered G1 as an example for illustration, the optical cable length corresponding to P1 and P2 on the G1 wire is L1, the optical cable length corresponding to P2 and P3 is L2, the optical cable length corresponding to P3 and P4 is L3, and so on.

[0056] In the embodiments of the present invention, by correlating the coordinates of the optical cable laying nodes with the lengths of the optical cables between adjacent optical cable laying nodes, the distance between any two nodes can be accurately calculated, facilitating fault location and network planning, and preparing for drawing virtual optical cable routes subsequently.

[0057] S250. Draw a virtual optical cable route according to the coordinates of the corresponding optical cable laying nodes and the lengths of the optical cables between adjacent optical cable laying nodes.

[0058] In the embodiments of the present invention, drawing a virtual optical cable route can visually present the structure of the optical cable network. When an optical cable failure occurs, the virtual optical cable route can help quickly locate the fault point, reduce the repair time, and improve the efficiency of troubleshooting.

[0059] S260. Perform a fault detection on the optical cables in the optical cable laying route to determine the distance from the fault point of the faulty optical cable to the detection point.

[0060] S270. Determine the position of the fault point in the virtual optical cable route according to the distance from the fault point of the faulty optical cable to the detection point.

[0061] Based on the above embodiments, optionally, S120. Determine the virtual optical cable route according to the coordinates of the optical cable laying nodes and the length of the optical cable between adjacent optical cable laying nodes, and may further include:

[0062] Fit the virtual optical cable route with the roads and the internal roads of buildings.

[0063] Specifically, the road refers to the road for vehicles, pedestrians and other means of transportation to pass through. Generally, it is planned and constructed by the government or relevant departments, and is divided into different levels, such as expressways, national highways, provincial highways, etc., with high traffic capacity and relatively standardized management. The internal road of a building refers to the road set inside a building or a building complex, usually used to connect various functional areas, parking lots, entrances and exits, etc. within the building. These roads may be sidewalks, vehicle lanes or service roads, and their design aims to improve the usage efficiency and safety of the building and facilitate the flow of people and materials.

[0064] In the embodiments of the present invention, fitting the virtual optical cable route with the roads and the internal roads of buildings can avoid the problem of incorrect fault location caused by the virtual optical cable route passing through buildings, thereby improving the reliability and maintenance efficiency of the optical cable fault location method.

[0065] The technical solution of the embodiments of the present invention determines the virtual optical cable route by corresponding the coordinates of the optical cable laying nodes with the length of the optical cable between adjacent optical cable laying nodes. The virtual optical cable route enables the operation and maintenance personnel to quickly locate the problem area when an optical cable failure occurs, thereby reducing the time for troubleshooting and repair and improving the overall response speed.

[0066] Figure 3 This is a flowchart of another optical cable fault location method provided by the embodiments of the present invention. Based on the above embodiments, optionally, S130. Perform a fault detection on the optical cables in the optical cable laying route to determine the distance from the fault point of the faulty optical cable to the detection point, can be further refined, such as Figure 3 As shown, the method includes:

[0067] S310. Obtain the coordinates of the optical cable laying nodes and the length of the optical cable between adjacent optical cable laying nodes according to the optical cable laying route.

[0068] S320. Determine the virtual optical cable route according to the coordinates of the optical cable laying nodes and the length of the optical cable between adjacent optical cable laying nodes.

[0069] S330. Conduct a fault detection on each optical cable in the optical cable laying route to determine the faulty optical cable.

[0070] In the embodiment of the present invention, an optical time domain reflectometer can be used to detect each optical cable to be detected one by one, and the faulty optical cable can be determined by analyzing the reflected optical signal. Determining the faulty optical cable can effectively reduce the scope of fault troubleshooting and reduce the fault troubleshooting time.

[0071] S340. Determine the distance from the fault point of the faulty optical cable to the detection point.

[0072] In the embodiment of the present invention, the optical time domain reflectometer can measure the distance from the fault point of the faulty optical cable to the detection point, that is, the actual length of the optical cable from the fault point to the detection point. According to the distance from the fault point of the faulty optical cable to the detection point, the position of the fault point in the virtual optical cable route can be located.

[0073] S350. Determine the position of the fault point in the virtual optical cable route according to the distance from the fault point of the faulty optical cable to the detection point.

[0074] The technical solution of the embodiment of the present invention determines the faulty optical cable by means of one-by-one detection and obtains the distance from the fault point of the optical cable to the detection point, which can effectively narrow the scope of fault troubleshooting and achieve accurate positioning of the fault point. That is, the present invention improves the speed and accuracy of optical cable fault location.

[0075] Figure 4 It is a flowchart of another optical cable fault location method provided by the embodiment of the present invention. On the basis of the above embodiments, optionally, S140. Determine the position of the fault point in the virtual optical cable route according to the distance from the fault point of the faulty optical cable to the detection point, which can be further refined, such as Figure 4 shown, the method includes:

[0076] S410. Obtain the coordinates of the optical cable laying nodes and the length of the optical cable between adjacent optical cable laying nodes according to the optical cable laying route.

[0077] S420. Determine the virtual optical cable route according to the coordinates of the optical cable laying nodes and the length of the optical cable between adjacent optical cable laying nodes.

[0078] S430. Conduct a fault detection on the optical cables in the optical cable laying route to determine the distance from the fault point of the faulty optical cable to the detection point.

[0079] S440. Determine the virtual cable route corresponding to the faulty cable in the virtual cable route.

[0080] In the embodiments of the present invention, each cable corresponds to a virtual cable. Determining the virtual cable route corresponding to the faulty cable can effectively narrow down the scope of fault troubleshooting and improve the reliability of fault troubleshooting.

[0081] S450. According to the distance from the fault point of the faulty cable to the detection point, determine the distance from the fault point of the faulty cable to the detection point in the virtual cable route.

[0082] Specifically, in the virtual cable route, the distance from the fault point of the faulty cable to the detection point is equal to the distance from the fault point of the detected faulty cable to the detection point. Determining the distance from the fault point of the faulty cable to the detection point in the virtual cable route can provide a data basis for subsequent positioning of the fault point.

[0083] S460. According to the distance and the cable length between adjacent cable laying nodes in the virtual cable route, determine the fault location of the faulty cable.

[0084] Specifically, according to the cable length between adjacent cable laying nodes in the virtual cable route and the distance from the fault point of the faulty cable to the detection point in the virtual cable route, by successive recursion starting from the detection point, the position of the faulty cable can be obtained.

[0085] Based on the above embodiments, optionally, S460. According to the distance and the cable length between adjacent cable laying nodes in the virtual cable route, determine the fault location of the faulty cable, including: determining that the fault point is between the first node coordinate and the second node coordinate according to the distance; positioning the position of the fault point of the faulty cable according to the first node coordinate and the second node coordinate.

[0086] Specifically, the first node coordinate refers to the coordinate of one of all the cable laying nodes, and the second node coordinate refers to the coordinate of another of all the cable laying nodes. In the embodiments of the present invention, the first node and the second node are adjacent cable laying nodes, where the distance from the first node to the detection point is shorter than the distance from the second node to the detection point. According to the cable length between adjacent cable laying nodes in the virtual cable route and the distance from the fault point of the faulty cable to the detection point in the virtual cable route, by successive recursion starting from the detection point, it can be determined that the fault point is between the first node coordinate and the second node coordinate. Then, according to the ratio of the distance from the fault point to the first node to the distance between the first node and the second node, the position of the fault point can be determined.

[0087] Based on the above embodiments, optionally, after determining the position of the fault point in the virtual optical cable route according to the distance from the fault point of the faulty optical cable to the detection point, it further includes: navigating to the fault point according to the virtual optical cable route.

[0088] In the embodiments of the present invention, navigating to the fault point through the virtual optical cable route can reduce the time for fault troubleshooting and repair, and improve the operation and maintenance efficiency of the optical cable.

[0089] The technical solution of the embodiments of the present invention locates the fault point between the first node coordinate and the second node coordinate through the fault position of the faulty optical cable, and then determines the position of the fault point, which can significantly reduce the misjudgment caused by inaccurate position and ensure the reliability of fault location. In addition, accurately locating the fault point can make the maintenance work of the optical cable more efficient, reduce unnecessary construction and repeated inspections, thereby reducing the maintenance cost and waste of human resources.
