Description

Technical Field

[0001] The present invention relates to the technical field of network intelligent detection, and in particular to an intelligent early warning method and device based on broadband fixed-line FTTH optical power fluctuation. Background Art

[0002] FTTH, short for "Fiber to the Home", is a technology that connects Internet services directly to users' homes through optical fibers. Compared with traditional copper-wire broadband, FTTH can provide faster transmission speeds and more stable network connections. Broadband fixed networks are part of access technologies such as FTTH (Fiber to the Home), and are mainly used to provide users with data, voice, video and other services. In FTTH networks, when optical fibers transmit signals, the optical power will fluctuate with factors such as the transmission distance of the signal, network load, and device status. The fluctuation of optical power will affect the stability of the network and the quality of the signal. If it cannot be handled in a timely manner, it may cause service interruption for a large number of users, increase operation and maintenance costs, and affect user experience.

[0003] At present, operators mainly manage the problem of optical power fluctuation through regular inspections and manual monitoring, and combine simple network management systems (NMS) to monitor optical power. When optical power abnormalities are detected, the system will generate a warning message, and the operation and maintenance personnel need to analyze and handle the faults according to the warning information. However, since the above methods rely on manual monitoring and regular inspections, it is difficult to detect the problem of optical power fluctuation in time, and since fault analysis and processing also rely on manual work, the response speed to faults is slow and inefficient.

[0026] This embodiment discloses an intelligent early warning method for optical power fluctuation based on broadband fixed-line FTTH network.

[0027] Reference Figure 1 The intelligent early warning method for optical power fluctuation based on broadband fixed-line FTTH includes the following steps:

[0028] S1: Data collection: Through the SNMP protocol, optical power values, device IDs, and timestamps are collected from each optical port device in the network, including PON optical power collection and optical modem optical power collection. These data provide a basis for subsequent big data analysis and fault prediction.

[0029] In addition to collecting the above-mentioned optical power data, it is also possible to collect multi-dimensional data such as the operating status of optical port equipment, environmental parameters such as humidity, temperature, network quality information, signal strength, optical signal-to-noise ratio, optical loss, wavelength, fiber link status information, optical power dynamic range, reflection loss, link quality, etc., to improve the accuracy and comprehensiveness of the analysis. In short, the amount of data that needs to be collected is determined by the scale and complexity of the network and the service quality requirements.

[0030] In addition, users’ offline records are collected from the business system to analyze data that may be related to optical power fluctuations. User device usage habits are integrated to form a complete data view.

[0031] In addition, it is necessary to set a reasonable acquisition frequency, such as once per second (1Hz), to ensure real-time performance. High-frequency acquisition can more accurately capture subtle fluctuations and sudden changes in optical power.

[0032] S2: Data preprocessing, including data cleaning, format conversion, data standardization and data enhancement.

[0033] Data cleaning: cleaning the collected data, including deleting duplicate data, correcting erroneous data, filling in missing data, ensuring the integrity and accuracy of the data, and identifying and correcting outliers through abnormal data algorithms, such as Z-score (standard deviation method), IQR (interquartile range method) and Boxp i ot (box plot).

[0034] Format conversion converts data from different sources into a unified format to facilitate subsequent processing and analysis, and uses standardized format data to improve the compatibility and scalability of the system.

[0035] Data standardization: standardize the optical power values ​​to eliminate the differences between devices with different optical ports, ensure the fairness and accuracy of data analysis, and use normalization or Z-score standardization methods to unify the measurement units of data.

[0036] Data enhancement, through interpolation, smoothing and other methods to enhance the data, reduce the impact of data missing and noise on the analysis results, the enhanced data can better reflect the actual fluctuation of optical power.

[0037] S3: Data analysis, including data mining, statistical analysis, anomaly detection, and trend analysis.

[0038] Data mining uses data mining algorithms, such as classification algorithms, clustering algorithms, and regression algorithms, to extract valuable information from large amounts of data, such as the changing trends and abnormal fluctuations of optical power values. In particular, cluster analysis can be used to identify different types of optical power fluctuation patterns.

[0039] Statistical analysis: Statistical analysis is performed on the optical power values ​​to calculate the mean, variance, standard deviation and other indicators to determine the range of normal optical power values. Through probability distribution analysis, the normal fluctuation range and abnormal fluctuation of optical power can be identified.

[0040] Anomaly detection uses anomaly detection algorithms to identify optical power values ​​that exceed the normal range and determine potential faulty optical ports. Algorithms such as isolation forest and support vector machines are used to improve the accuracy and reliability of anomaly detection.

[0041] Trend analysis: perform time series analysis on optical power data to identify long-term trends and periodic fluctuations and predict future optical power trends.

[0042] S4: Fault prediction, including feature extraction, model training, model validation, and model optimization.

[0043] Feature extraction: extract key features from the analysis data, such as optical power fluctuation amplitude, fluctuation frequency, fluctuation period, fluctuation mutation point, etc., to construct a multi-dimensional feature space.

[0044] Model training uses machine learning algorithms, such as support vector machines, decision trees, neural networks, etc., to train historical data and establish a fault prediction model. Feature engineering is also used to improve the training effect of the model.

[0045] Model validation: The model is validated through cross-validation, leave-one-out method and other methods to evaluate its prediction accuracy and robustness. And the confusion matrix, ROC curve and other evaluation indicators are used to quantify the model performance.

[0046] Model optimization: continuously optimize the fault prediction model, and use ensemble learning, hyperparameter tuning and other technologies to improve the model's generalization ability and prediction accuracy.

[0047] S5: Intelligent early warning, including real-time data collection, real-time prediction, multi-level early warning mechanism, automatic dispatch and closed-loop feedback.

[0048] Real-time data collection, constantly collect new data from the network, pre-process and store it. Use distributed data storage and processing technology to ensure the efficiency and scalability of the system.

[0049] Real-time prediction: input new data into the fault prediction model, make real-time predictions, and output warning results. The real-time prediction system can quickly respond to sudden changes in optical power and provide timely fault warnings.

[0050] Multi-level warning mechanism: According to the severity of the warning results, a multi-level warning mechanism is set up, from general warning to emergency warning, and different treatment measures are taken respectively. The multi-level warning mechanism can effectively distinguish different degrees of optical power fluctuations and improve processing efficiency.

[0051] Automatic dispatching: Based on the early warning results, the artificial intelligence system automatically generates work orders and dispatches them to relevant maintenance personnel to ensure timely processing. The work order system records the detailed process and results of each fault handling, providing data support for subsequent analysis.

[0052] Closed-loop feedback: After the maintenance personnel have handled the fault, they will feed back the processing results to the system. The system will optimize the fault prediction model based on the feedback results to achieve closed-loop management of fault handling.
