As Figure 1 shown, the method corresponds to an application in a device as Figure 2 shown.

[0056] Specifically, the optical cable fault line environment visualization monitoring method provided in this embodiment mainly realizes the synchronization of optical cable fault location and video monitoring data information, intelligently generates fault visualization reports and troubleshooting solutions, and solves the problems of low efficiency and accuracy of manual detection and troubleshooting. By combining the existing in-network video monitoring network and optical cable line fault location, the line is supervised and regularly detected. When a fault is found in the optical cable line, the positioning system detects the fault range, and the video monitoring network simultaneously retrieves the surrounding monitoring points within this range, and schedules the real-time and playback video materials at the time of the fault. It intelligently analyzes and judges the precise fault point and the cause of occurrence, generates a precise fault location visualization report and a troubleshooting solution, and pushes them to the emergency troubleshooting department in the first time, improving the efficiency and accuracy of optical cable troubleshooting.

[0057] In one embodiment, the method further includes pre-collecting historical optical cable fault data to establish an optical cable fault model database, specifically including:

[0058] Pre-collecting historical optical cable fault location point measurement information and historical optical cable fault location point-related visualization information to establish a historical optical cable fault feature library;

[0059] Pre-collecting historical optical cable fault causes and corresponding historical optical cable fault solutions to establish an optical cable fault cause library and an optical cable fault solution library;

[0060] Pre-establishing the corresponding relationship between the optical cable fault cause library and the historical optical cable fault feature library to form an optical cable fault model database;

[0061] The optical cable fault model database is used to assist in locating the current optical cable fault area, obtaining current optical cable fault-related visualization information, and obtaining the location point, cause, and solution of the current optical cable fault.

[0062] In this embodiment, the architecture of the method and its corresponding device is as Figure 3 shown, mainly including a fault location module, a transmission communication module, a visualization monitoring module, an intelligent retrieval and early warning module, etc. Among them, the intelligent retrieval and early warning module is the core key part. This core part includes a pre-set fault occurrence model database (optical cable fault model database). Through the fault occurrence model database, it intelligently analyzes and judges the precise fault point and the cause of occurrence. The fault occurrence model database contains typical features, possible causes, influence ranges, and historical cases of various optical cable faults.

[0063] The pre-setting includes: ① Data collection: Collect and analyze historical optical cable fault data, including fault types, causes of occurrence, influence ranges, etc.; ② Model establishment: Based on the collected data, establish a fault model database, including a fault feature library, a cause library, and a solution library; ③ Continuous optimization: According to the addition of fault cases, continuously optimize and update the database to improve the accuracy and efficiency of fault identification.

[0064] In one embodiment, establishing the correspondence between the optical cable fault cause library and the historical optical cable fault feature library specifically includes:

[0065] Obtaining the historical optical cable fault type of the historical optical cable fault location point according to the historical optical cable fault location point measurement information. The optical cable fault type includes at least one of the optical cable break point and the optical attenuation point. Obtaining the fault source geographical range and the fault source time range of different historical optical cable fault types according to the relevant visualization information of the historical optical cable fault location point. The fault source time range includes the first fault source duration of the optical cable break point and the second fault source duration of the optical attenuation point;

[0066] Establishing the correspondence between the historical optical cable fault cause and the relevant visualization information of the historical optical cable fault location point. The optical cable fault causes include at least one of the optical cable being dug up, the optical cable aging, the optical cable being damaged by vibration, the optical cable being bitten, and the optical cable being burned. The corresponding relevant visualization information includes optical cable break + sharp change in the light of the relevant pipeline environment + construction in the relevant ground environment, no visible physical damage to the optical cable + no obvious change in the relevant pipeline environment + no construction in the relevant ground environment, no visible physical damage to the optical cable + obvious vibration in the relevant pipeline environment + construction in the relevant ground environment, damage on the surface of the optical cable + movement of animals in the relevant pipeline environment + no construction in the relevant ground environment, the surface of the optical cable being burned + fire signal in the relevant pipeline environment.

[0067] In this embodiment, Figure 2 The measurement and positioning unit 1 mainly corresponds to Figure 3 The fault location module in, and at the same time involves some functions of the intelligent retrieval and warning module. Mainly after the fault location module discovers a fault, it compares historical cases through the intelligent retrieval and warning module to determine the fault area monitoring equipment to be called (retrieving the monitoring points in the fault area); Figure 2 The visualization unit 2 mainly corresponds to Figure 3 The visualization monitoring module in, and at the same time involves some functions of the intelligent retrieval and warning module. Mainly by comparing historical cases through the intelligent retrieval and warning module, determining the video time that the fault area monitoring equipment needs to trace back, and obtaining the video materials within the current and traced-back time; Figure 2 The analysis unit 3 mainly corresponds to Figure 3 The intelligent retrieval and warning module in, mainly realizing the positioning of the fault, the cause analysis, and the suggestion of an effective solution.

[0068] In one embodiment, S1. Locating the current optical cable fault area according to the current optical cable fault measurement information, specifically including:

[0069] Using the optical time domain reflectometer OTDR to obtain the current optical cable fault measurement information;

[0070] Judge the current optical cable fault point according to the current optical cable fault measurement information, and obtain the type and distance of the current optical cable fault point;

[0071] According to the type and distance of the current optical cable fault point, combined with the Geographic Information System (GIS) and the geographical scope of the fault source, locate the current optical cable fault area.

[0072] In this embodiment, as Figure 3 shown in the fault location module, the internal bending attenuation or break point of the optical fiber is detected by an OTDR (Optical Time Domain Reflectometer), and the problem area in the optical fiber is located. Combining wavelet transform and GIS (Geographic Information System) technology, the distance and type of the optical cable fault point are located. The fault point types include optical attenuation points and optical cable break points. The optical cable break points can usually be located in the visual video material. The environmental video material near the visual physical damage location can be further obtained as data for analyzing the cause of the damage, narrowing the geographical scope of obtaining the video material.

[0073] OTDR is a technology widely used in the communication industry. As a precision optical fiber test instrument, the optical time domain reflectometer can be used for the maintenance, fault troubleshooting and performance monitoring of optical fiber networks. The optical time domain reflectometer injects a series of optical surges into the optical fiber for inspection. The inspection method is to receive the optical signal from the same side where the surge is injected. Since the injected signal encounters media with different refractive indices, it will scatter and reflect back. The intensity of the reflected optical signal is measured and is a function of time. Therefore, it can be converted into the length of the optical fiber to determine the range of the fault site. The optical time domain reflectometer can be used to measure the length and attenuation of the optical fiber, including the fusion joints and transfer joints of the optical fiber. It can also be used to measure the break point when the optical fiber is broken.

[0074] In an embodiment, S2. Obtain the current optical cable fault-related visualization information according to the current optical cable fault area, specifically including:

[0075] Obtain the visualization information of the optical cable line in the current optical cable fault area obtained by the current monitoring of the optical cable pipeline monitoring equipment in the current optical cable fault area, and judge whether there is visual physical damage to the current optical cable according to the visualization information of the optical cable line in the current optical cable fault area;

[0076] If so, obtain the occurrence point and occurrence time point of the visual physical damage, and obtain the visualization information of the pipeline environment at the optical cable fault occurrence point obtained by the optical cable pipeline monitoring equipment at the occurrence point within the first fault source duration before the occurrence time point, and the visualization information of the ground environment at the optical cable fault occurrence point obtained by the ground monitoring equipment at the occurrence point.

[0077] Otherwise, obtain the visual information of the pipeline environment in the optical cable fault area monitored by the optical cable pipeline monitoring equipment in the current optical cable fault area within the second fault source duration before the current time point, and the visual information of the ground environment in the optical cable fault area monitored by the ground monitoring equipment in the current optical cable fault area.

[0078] In this embodiment, as Figure 3 shown, the intelligent retrieval module (part of the intelligent retrieval and early warning module) first determines a physical range containing the fault point according to the fault location information provided by the optical cable fault location module (resource longitude and latitude, optical cable length, length of the pipeline through which the optical cable passes), and at the same time uses GIS positioning technology combined with the monitoring equipment location information (longitude and latitude, map positioning, etc.) based on the fault point positioning coordinates to find all the monitoring equipment in the visual monitoring module within the fault range, retrieves the monitoring equipment whose monitoring perspective area overlaps with the fault range area, and combines the online status of the monitoring equipment and whether it supports remote call to confirm the retrospective time range according to the time of the fault alarm, including the video records within a period of time before the fault occurs. The specific duration can be preset according to the fault type, such as 5 minutes, 10 minutes or longer, and call the real-time and traceability video materials of this part of the monitoring equipment. The determination of the video traceability duration can be based on historical experience. For example, for the optical cable break state, the time point of the optical cable break can be found in the video, and then traced back according to this time point. For the situation without obvious physical damage, the video materials between the last monitoring time and the current monitoring time can be traced back, etc.

[0079] In an implementation manner, S3. According to the current visual information related to the optical cable fault, obtain the positioning point, cause and solution of the current optical cable fault, specifically including:

[0080] Obtain the abnormal information of the current optical cable fault line environment according to the current visual information related to the optical cable fault. The abnormal information of the current optical cable fault line environment includes visual physical damage to the current optical cable, abnormality in the current relevant pipeline environment, and abnormality in the current relevant ground environment;

[0081] Obtain the positioning point of the current optical cable fault according to the position point of the monitoring equipment for the abnormal information of the current optical cable fault line environment, and compare the abnormal information of the current optical cable fault line environment with the optical cable fault model database to obtain the cause and corresponding solution of the current optical cable fault.

[0082] In this embodiment, as Figure 3As shown in the figure, the intelligent retrieval and early warning module analyzes the optical cable fault based on real-time and traceable materials. The specific process of analysis and judgment through the pre-set fault occurrence model database includes: ① Feature extraction: Extract features related to the fault from the monitoring video, such as light changes, object movement, etc.; ② Pattern matching: Match the extracted features with the patterns in the fault model database to find the most similar fault cases; ③ Cause inference: Based on the matching results, infer the possible causes of the fault; ④ Solution generation: According to the inferred causes, select or generate corresponding troubleshooting solutions from the solution library.

[0083] In the monitoring video, the feature extraction methods include: Light change detection: Detect the change in light intensity by comparing the brightness differences between consecutive frames, which is used to identify events such as the optical cable being dug up or blocked; Object movement detection: Use algorithms such as background subtraction or optical flow method to detect the movement of objects in the video, such as construction vehicles, personnel activities, animal movement, etc., which may be related to the optical cable fault; Color and texture analysis: Analyze the color and texture features in the video to identify whether the surface of the optical cable is damaged or covered.

[0084] The extracted features are matched with the patterns in the fault model database. The pattern matching algorithms include: Template matching: Directly compare the extracted features with the templates in the database to find the most similar match; Machine learning algorithms: Support Vector Machine (SVM), neural network, etc. These algorithms can learn the complex relationships between features and fault types and perform more accurate matching; Deep learning algorithms: Such as Convolutional Neural Networks (CNN), which can automatically learn feature representations from data and perform efficient pattern matching.

[0085] Cause inference is based on the results of pattern matching, combined with the knowledge and experience in the fault model database, to infer the possible causes of the fault. The inference methods include: Similarity analysis: According to the results of pattern matching, calculate the similarity between the extracted features and each fault pattern in the database, and select the fault pattern with the highest similarity as the basis for inference; Causal chain analysis: Combine the typical features and possible causes of the fault pattern to construct a causal chain and analyze the possible causes of the fault occurrence; Probability reasoning: Use probability reasoning methods such as Bayesian networks, combined with historical data and knowledge base, to calculate the probabilities of each cause and select the most likely cause as the inference result.

[0086] Different matching results and feature extractions correspond to different fault types and cause inferences. The following are some common corresponding relationships: Sharp light change: If the light changes sharply within a short period of time and there is an object movement (such as a construction vehicle) accompanied, it may be inferred that the optical cable has been dug through; Continuous light weakening: If the light continuously weakens and there is no obvious object movement, it may be inferred that the optical cable is aging or the joint is loose; Object movement accompanied by optical cable jitter: If the optical cable jitters when an object (such as construction equipment) moves in the surveillance video, it may be inferred that the optical cable has been damaged by the construction equipment; Abnormal color and texture: If the color or texture on the surface of the optical cable appears abnormal (such as damage, charring, etc.), it may be inferred that the optical cable has suffered physical damage or events such as fire.

[0087] In one embodiment, obtaining the cause of the current optical cable fault and the corresponding solution specifically includes:

[0088] Obtaining that the cause of the current optical cable fault is at least one of the optical cable being dug through, the optical cable aging, the optical cable being damaged by vibration, the optical cable being bitten, and the optical cable being charred;

[0089] Obtaining the solution to the current optical cable fault according to the cause of the current optical cable fault, including a combination of at least some of replacing the optical cable and adding warnings, recording the aging cycle of the optical cable, preventing rodent damage, and overhauling the circuit.

[0090] In this embodiment, combining video materials to output a troubleshooting plan or a warning prompt, the information includes: ① Fault location: Based on the double verification of OTDR positioning and video surveillance, accurately pointing out the location of the fault point; ② Fault type and cause: Based on the matching result of video analysis and the fault model database, determining the type and possible cause of the fault; ③ Troubleshooting plan or warning prompt: Providing specific troubleshooting steps and suggestions for the fault type and cause. Since the cause of the optical cable fault is deeply analyzed, the corresponding troubleshooting suggestions, in addition to the repair operation of replacing the optical cable for the fault point, may also include corresponding preventive measures, such as adding warnings to avoid construction damage, summarizing and recording the aging cycle of the optical cable for convenient fixed-point detection, preventing rodent damage, etc. to avoid the optical cable being bitten by animals, overhauling the circuit to avoid problems such as overheating fire of the optical cable, so as to further improve the troubleshooting effect.

[0091] In one embodiment, after S3, obtaining the positioning point, cause, and solution of the current optical cable fault according to the visualization information related to the current optical cable fault, the method further includes:

[0092] Generating a visualization report on the optical cable fault handling, including the positioning point, cause, and solution of the current optical cable fault in the report;

[0093] Pushing the report to the optical cable fault troubleshooting personnel and receiving the troubleshooting information fed back by the troubleshooting personnel.

[0094] In this embodiment, as Figure 3 shown, the report output includes: after integrating the troubleshooting solutions or warning prompts with the video materials, integrating the above information into an intuitive visual report, including content information such as the fault location, video screenshots, fault descriptions, cause analysis, and troubleshooting solutions. Finally, the transmission and communication module pushes the visual report data to the emergency troubleshooting department to complete the corresponding business handling.

[0095] By outputting the visual report, the following effects can be achieved: ① Quick response: According to the received fault location and troubleshooting solutions, quickly organize personnel and equipment to the site; ② Precise troubleshooting: Based on the provided fault types and causes, adopt targeted troubleshooting measures to improve the troubleshooting efficiency and accuracy; ③ Follow-up tracking: During the troubleshooting process, continuously track the progress of fault handling and adjust the troubleshooting solutions if necessary; ④ Experience summary: Feed back the fault handling process and results to the fault model database to provide richer and more accurate data support for future fault troubleshooting and warning.

[0096] In addition, this embodiment can also adopt the following technologies to improve the effect of visual monitoring of the optical cable fault line environment: High-precision monitoring technology: It can accurately and real-time obtain various data of the environment around the optical cable line, such as temperature, humidity, vibration, etc., providing accurate basic information for fault judgment; Effective visualization means: Present the monitored data to the operation and maintenance personnel in a clear and intuitive manner to help them quickly understand the line environment conditions and quickly locate possible fault points; Intelligent analysis and warning function: Through the analysis of the monitored data, it can automatically judge potential fault risks and issue warnings in a timely manner so as to take preventive measures; Adapt to complex environments: It can work stably and reliably under various harsh natural and human environment conditions to ensure the continuity and accuracy of monitoring; Low energy consumption and long battery life: Adopt energy-saving technologies so that the monitoring equipment can operate for a long time without frequent power supply replacement or charging; Reliability of data transmission: Ensure that the monitored data can be stably and quickly transmitted to the backend processing system to avoid data loss or delay; Compatibility and scalability: It can be compatible and integrated with the existing optical cable monitoring system or other related devices, and at the same time has good scalability to adapt to future technological development and new requirements; Cost-effectiveness: Control the cost of the monitoring equipment on the premise of ensuring the monitoring effect so that it has a high cost performance in practical applications.

[0097] A specific application example of the method in this embodiment is planned to be applied to the software development for the detection of the base station Internet of Things environment.

[0098] Background: As the southern gateway of a company's international communication, a certain city is responsible for 78% of the international dedicated lines and 21 heavily protected OBS circuits in the whole province. At the same time, the 790 km provincial and municipal trunk lines within the city are all important transmission services. In the daily maintenance work in recent years, when there are construction works such as municipal, gas, and water supply, the optical cables are damaged, resulting in service interruptions. Especially in high-risk areas such as the exit of the core aggregation computer room, where there are multiple trunk optical cables and important large customers, such service interruptions will bring serious impacts and consequences to the company. All along, the branch company has invested a large amount of manpower and material resources in issues such as response time and fault location, and has tried its best to reduce the failure rate and shorten the repair duration. However, the current pure manual working method has relatively low efficiency and cannot meet the daily maintenance requirements.

[0099] Objective: To address the growing demand for the stability and security of important resources due to the increasing network scale, it is urgent to seek an efficient and stable monitoring strategy for important business environments to achieve functions such as multi-professional comprehensive automatic inspection, hidden danger monitoring and investigation, and base station environmental safety monitoring. Therefore, a software platform has been developed, which cooperates with a third-party Internet of Things monitoring platform to improve work efficiency and network stability, and mainly achieves the following three objectives:

[0100] ① Monitoring and management: Through the deployment of high-definition cameras and the construction of a third-party Internet of Things monitoring platform, the number of high-definition cameras deployed in the first phase of the project is not less than 100, to achieve the supervision of the important optical cable environment in a certain city, and the data such as environmental monitoring pictures and changes in antenna feeder indicators are transmitted back, to avoid optical cable interruptions caused by human or construction reasons;

[0101] ② Inspection and management: Based on the functions of the third-party platform, according to the daily work needs of the company, functions such as video inspection strategy customization, environmental safety control, and analysis and statistics of inspection results are added to further expand the effectiveness and practicality of monitoring, improve network stability, and enhance network operation efficiency;

[0102] ③ Fault management: When a fault occurs or a hidden danger is found during the patrol, an automatic notification strategy is adopted. The maintenance responsible person is dispatched through digital methods such as voice robots in the first time, and a maintenance work order is sent in the form of a work order, and strict and detailed assessment rules are formulated to urge the maintenance personnel to eliminate hidden dangers and repair faults in a timely manner.

[0103] Achievement: The environmental detection data collected by the base station and connected to the network completes management work such as patrol, analysis, and prediction according to the established functions, and can achieve rapid early warning and rapid notification of abnormal situations. Through this project, it can be promoted to other scenarios involving environmental detection in the future, and can also be promoted to other branch companies for application to achieve refined management of target resources, so as to meet the improvement of network resource stability and security.
