Description

Technical Field

[0001] This invention relates to a method and related equipment for the standardized processing of operation and maintenance alarm data for QKD devices, belonging to the field of quantum communication network data processing and intelligent operation and maintenance. Background Technology

[0002] As Quantum Key Distribution (QKD) networks gradually move from experimental environments to practical deployments, network scale continues to expand, and the number of devices increases, leading to a surge in alarm records, inspection records, status logs, and fault handling information generated during operation. During continuous operation, QKD devices generate massive amounts of maintenance alarm-related data, including device operation logs, real-time status alarms, records exported from network management systems, on-site inspection records, and fault handling records. This data has three core characteristics: First, its sources are diverse, including both structured / semi-structured data automatically generated by devices and network management systems, as well as unstructured data manually entered; second, its formats are heterogeneous, with different manufacturers' devices and network management systems having completely different definitions, naming, and formats for alarm fields, resulting in multiple different expressions for the same type of fault alarm; and third, its quality is inconsistent, with a large amount of raw data exhibiting problems such as mixed use of Chinese and English, missing fields, ambiguous location descriptions, and non-standard formats. Currently, the processing of the aforementioned alarm data in QKD network maintenance still has significant shortcomings: First, the industry has not yet formed a unified data standard for QKD equipment operation and maintenance alarms. Alarm data from different manufacturers cannot be uniformly queried, compared and correlated across platforms and systems, resulting in serious data silos that cannot support the global operation and maintenance management of large-scale QKD networks.

[0003] Second, the existing processing method is highly dependent on manual labor. Operation and maintenance personnel need to read, classify, and fill in the forms manually to complete the alarm data. This not only involves a huge workload and extremely low processing efficiency, but also easily leads to human errors such as alarm omissions, fault misjudgments, and inconsistent formats. It is completely unable to meet the operation and maintenance needs after the large-scale development of QKD networks.

[0004] Third, existing alarm data processing solutions for traditional communication networks cannot adapt to the unique operation and maintenance scenarios of QKD devices. QKD devices have unique technical architectures such as quantum layer, optical layer, electronic control layer, and service layer, and have a large number of unique alarm types that are not found in traditional communication devices. General solutions cannot accurately identify QKD-specific alarm terms, and the accuracy of field extraction and standardization processing is extremely low.

[0005] Fourth, the existing solution does not form a complete processing loop, lacks compliance verification and anomaly reprocessing mechanisms for the parsing results, cannot guarantee the quality of the output data, and cannot provide a reliable data foundation for subsequent fault location, operation and maintenance analysis, and knowledge accumulation.

[0006] Therefore, developing a standardized processing method for operation and maintenance alarm data that is adapted to the specific scenarios of QKD devices, fully automated throughout the process, and can guarantee data quality has significant engineering application value and practical industry significance. Summary of the Invention

[0007] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a standardized processing method and related equipment for operation and maintenance alarm data of QKD devices. This method solves the core problems of the existing technology, such as scattered sources of QKD alarm data, heterogeneous formats, reliance on manual processing, poor adaptability of general solutions, lack of closed-loop processing, and inability to guarantee the quality of output data. It provides a unified, reliable, and high-quality data foundation for the intelligent operation and maintenance of large-scale QKD networks.

[0008] To achieve the above objectives, the present invention is implemented using the following technical solution: In a first aspect, the present invention provides a method for standardizing the processing of operation and maintenance alarm data for QKD devices, including: A standard field system for alarm data adapted to the operation and maintenance scenarios of quantum key distribution (QKD) devices is established in advance, along with a standardized alarm template corresponding to the standard field system. Obtain the original multi-source alarm dataset, which includes automated device alarm data and manually entered operation and maintenance alarm data; The original multi-source alarm dataset is preprocessed to obtain a multi-source alarm dataset; Based on the pre-built QKD device basic information database, the alarm data in the multi-source alarm dataset is subjected to structured field extraction to obtain the parsing results corresponding to the standard field system; Based on the preset QKD alarm standardization mapping rules, the parsing results are filled in and normalized to obtain standardized alarm records that conform to the standardized alarm template. Standardized alarm records that conform to the standardized alarm template are stored in the database.

[0009] Optionally, the core fields of the standard field system include alarm name, alarm category, alarm status, alarm level, alarm location, alarm time, and alarm data.

[0010] Optionally, the automated alarm data of the device includes QKD device operation logs, real-time status output data, device monitoring interface return results, device terminal output information, and alarm and event records exported from the QKD network management system. The manually entered maintenance alarm data includes inspection records, manually filled fault records, fault handling records, and manually supplemented information.

[0011] Optionally, the preprocessing includes: sequentially performing text cleaning, abnormal character removal, time format unification, field splitting, duplicate information screening, and basic semantic normalization operations.

[0012] Optionally, the pre-built QKD device basic information database stores basic attribute information of all types of QKD devices in advance; the basic attribute information includes device name, device unique number, device model, device manufacturer, device type, installation location, network node to which it belongs, and associated link information; Optionally, structured field extraction is performed on the alarm data in the multi-source alarm dataset, including: S41: Traverse the multi-source alarm dataset, and for the current alarm data to be processed, retrieve the basic attribute information of the QKD device corresponding to the alarm data from the pre-built QKD device basic information database; S42: Input the retrieved basic attribute information and the current alarm data to be processed into the intelligent agent parsing module, and sequentially perform element identification, core content extraction and field mapping processing in accordance with the standard field system to obtain the candidate parsing result of the alarm data; the intelligent agent parsing module is a semantic parsing model obtained by fine-tuning based on the QKD operation and maintenance domain corpus; S43: Perform format compliance verification on the candidate parsing results of the alarm data. The compliance verification includes at least field integrity verification, time format standardization verification, and alarm level value compliance verification. S44: If the verification passes, the candidate parsing result of the alarm data is used as the parsing result of the alarm data. If the verification fails, return to step S41 to re-parse the alarm text until the verification passes.

[0013] Optionally, the preset QKD alarm standardization mapping rules include: alarm name synonym mapping table, alarm level mapping rules, alarm classification mapping rules, and alarm location standardization mapping rules; The alarm name synonym mapping table includes the standard correspondence between synonymous alarm descriptions, Chinese and English terms, and manufacturer-defined alarm names in QKD operation and maintenance scenarios; the alarm level mapping rule realizes the unified conversion between manufacturer-defined alarm levels and preset standard alarm levels; the alarm location standardization mapping rule organizes fuzzy location descriptions into a hierarchical standard format of node-data center-rack-device-port.

[0014] Secondly, this invention provides a system for standardizing operation and maintenance alarm data processing based on QKD devices, including: The initial module is used to pre-establish a standard field system for alarm data that is adapted to the operation and maintenance scenarios of quantum key distribution (QKD) devices, as well as a standardized alarm template corresponding to the standard field system; The data acquisition module is used to acquire the original multi-source alarm dataset, which includes automated device alarm data and manually entered operation and maintenance alarm data; The preprocessing module is used to preprocess the original multi-source alarm dataset to obtain a multi-source alarm dataset. The parsing module is used to extract structured fields from the alarm data in the multi-source alarm dataset based on the pre-built QKD device basic information database, and obtain the parsing results corresponding to the standard field system. The completion module is used to complete and normalize the fields of the parsing result based on the preset QKD alarm standardization mapping rules, so as to obtain standardized alarm records that conform to the standardized alarm template. The output module is used to store standardized alarm records that conform to the standardized alarm template into the database.

[0015] Thirdly, the present invention provides an electronic device, comprising: a memory and a processor; The memory is used to store programs; The processor is used to execute the program to implement the standardized processing method for operation and maintenance alarm data of QKD devices as described in the first aspect.

[0016] Fourthly, the present invention provides a readable storage medium having a computer program stored thereon, wherein when the computer program is executed by a processor, it implements the method for standardizing maintenance alarm data processing for QKD devices as described in the first aspect.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: This invention proposes a standardized processing method and related equipment for operation and maintenance alarm data of QKD devices. It addresses the core industry pain points in the large-scale deployment of quantum key distribution networks, such as the dispersed sources of operation and maintenance alarm data, heterogeneous formats, lack of unified standards for field definitions, high dependence on manual processing, and the inability of existing general solutions to adapt to the specific operation and maintenance scenarios of QKD. It provides a complete, closed-loop standardized processing solution for QKD device operation and maintenance alarm data. First, by pre-establishing a dedicated alarm data standard field system and standardized alarm templates adapted to QKD device operation and maintenance scenarios, a core standard was established for the unified processing of multi-source heterogeneous data. Second, by synchronously collecting all alarm data automatically generated and manually entered by the devices, the alarm information sources across all QKD operation and maintenance scenarios were fully covered. Third, standardized preprocessing was used to normalize the raw data, providing high-quality input for subsequent analysis. Fourth, based on a pre-built QKD device basic information database, structured field extraction was completed, enabling accurate identification and extraction of QKD-specific alarm content. Fifth, pre-set standardized mapping rules were used to complete field completion and normalization, ultimately generating standardized alarm records with uniform format, consistent expression, and complete fields, which were then uniformly stored in the database. This solution fundamentally addresses the core issue of the inability to uniformly query, compare, and analyze QKD operation and maintenance alarm data across manufacturers and systems. It replaces the inefficient traditional method of manually organizing each alarm data item by item, achieving fully automated and standardized processing of QKD operation and maintenance alarm data. This provides a unified, reliable, and high-quality data foundation for the global operation and maintenance management, fault location, and intelligent operation and maintenance system construction of large-scale QKD networks.

[0019] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

[0020] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of this disclosure.

[0021] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0022] The application principle of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] Example 1 like Figure 1 As shown in the figure, this embodiment of the invention provides a method for standardizing the processing of operation and maintenance alarm data for QKD devices, including the following steps: S1: Pre-establish a standard field system for alarm data that is adapted to the operation and maintenance scenarios of quantum key distribution (QKD) devices, and a standardized alarm template corresponding to the standard field system; S2: Obtain the original multi-source alarm dataset, which includes automated device alarm data and manually entered maintenance alarm data; S3: Preprocess the original multi-source alarm dataset to obtain a multi-source alarm dataset; S4: Based on the pre-built QKD device basic information database, the alarm data in the multi-source alarm dataset is subjected to structured field extraction to obtain the parsing results corresponding to the standard field system; S5: Based on the preset QKD alarm standardization mapping rules, the parsing results are filled in and normalized to obtain standardized alarm records that conform to the standardized alarm template. S6: Store the standardized alarm records that conform to the standardized alarm template in the database.

[0024] In this embodiment, the core fields of the standard field system in step S1 include alarm name, alarm category, alarm status, alarm level, alarm location, alarm time, and alarm data. Each field has clearly defined naming rules, data format, and value boundaries. Among these features, alarm names serve as standardized core identifiers for alarm events, used for unified retrieval and aggregation analysis of similar alarms; alarm classification is based on a two-level standardized division of the technical architecture of QKD devices at the quantum layer, optical layer, electrical control layer, service layer, and system layer, enabling precise categorization of alarm events; alarm status and alarm level clearly define the four-stage standard identifiers for the entire alarm handling process and the four-level priority division of the fault impact, adapting to unified operation and maintenance scheduling of cross-vendor devices across the entire network; alarm location adopts a hierarchical standard format of "belonging network node-data center-rack-device-port" to achieve precise fault location; alarm time is uniformly formatted in the East Eight Zone standard format, providing a unified time reference for cross-device and cross-node alarm time sequence correlation analysis; alarm data retains the original alarm content completely and without modification, ensuring the traceability and verifiability of alarm events.

[0025] In this embodiment, the automated alarm data in step S2 includes QKD device operation logs, real-time status output data, device monitoring interface return results, device terminal output information, and alarm and event records exported from the QKD network management system; the manually entered maintenance alarm data includes inspection records, manually filled fault records, fault handling records, and manually supplemented information. Specifically, the automated alarm data comprehensively collects the operation logs, real-time status output data, device monitoring interface return results, device terminal output information, and alarm and event records exported from the network management system automatically generated throughout the entire operating cycle of all 86 QKD devices in the network, ensuring complete and comprehensive collection of the original device alarm data. The manually entered maintenance alarm data simultaneously collects on-site inspection records, manually filled fault records, fault handling closed-loop records, and manually supplemented alarm information, achieving complete matching and aggregation of automatically collected device data and on-site manual maintenance data, providing a comprehensive and closed-loop raw data foundation for subsequent standardized processing throughout the entire process.

[0026] In this embodiment, the preprocessing in step S3 includes: sequentially performing text cleaning, abnormal character removal, time format unification, field splitting, duplicate information screening, and basic semantic normalization operations.

[0027] Specifically, text cleaning and abnormal character removal operations include removing redundant spaces, line breaks, garbled characters, and invalid special symbols from the original text, and unifying full-width and half-width characters; time format unification operations convert timestamps, manufacturer-defined time formats, and times from different time zones to the standard format of East Eight Zone; field splitting operations split multi-field content merged in the same cell or row into independent field content; duplicate information screening operations identify duplicates based on the device's unique number, alarm time, and alarm core semantics, and remove completely duplicate redundant records; basic semantic normalization operations unify the conversion of content that mixes Chinese and English, such as converting "Link Down" to "Link Interruption" and "Rx Power Low" to "Received Optical Power Too Low", and performing preliminary alignment of different abbreviations of the same semantic meaning.

[0028] In this embodiment, the basic attribute information of all types of QKD devices is pre-stored in the QKD device basic information database pre-built in step S4; the basic attribute information includes device name, device unique number, device model, device manufacturer, device type, installation location, network node to which it belongs, and associated link information; like Figure 2 As shown, in this embodiment, step S4 involves extracting structured fields from the alarm data in the multi-source alarm dataset, including: S41: Traverse the multi-source alarm dataset, and for the current alarm data to be processed, retrieve the basic attribute information of the QKD device corresponding to the alarm data from the pre-built QKD device basic information database; S42: Input the retrieved basic attribute information and the current alarm data to be processed into the intelligent agent parsing module, and sequentially perform element identification, core content extraction and field mapping processing in accordance with the standard field system to obtain the candidate parsing result of the alarm data; the intelligent agent parsing module is a semantic parsing model obtained by fine-tuning based on the QKD operation and maintenance domain corpus; S43: Perform format compliance verification on the candidate parsing results of the alarm data. The compliance verification includes at least field integrity verification, time format standardization verification, and alarm level value compliance verification. S44: If the verification passes, the candidate parsing result of the alarm data is used as the parsing result of the alarm data. If the verification fails, return to step S41 to re-parse the alarm text until the verification passes.

[0029] Specifically, the intelligent agent parsing module adopts a named entity recognition model based on the BERT base model with fine-tuning. The fine-tuning corpus includes three years of historical alarm records of the network, QKD equipment operation and maintenance manuals from various manufacturers, fault handling documents, and quantum communication operation and maintenance industry standards. The module optimizes the specific terminology and semantic features for QKD operation and maintenance scenarios.

[0030] Specifically, step S43 performs a format compliance check on the candidate parsing results of the alarm data, which includes: Field integrity check: Checks whether the required fields in the standard field system have valid values ​​and no empty values; Time format conformity check: Check whether the alarm time field conforms to the preset format, that is, the standard format of East 8th time zone; Alarm level value compliance verification: Check whether the alarm level field is within the standard value range of "urgent, important, general, alert"; In this embodiment, the QKD alarm standardization mapping rules preset in step S5 include: alarm name synonym mapping table, alarm level mapping rules, alarm classification mapping rules, and alarm location standardization mapping rules. The alarm name synonym mapping table includes the standard correspondence between synonymous alarm descriptions, Chinese and English terms, and manufacturer-defined alarm names in QKD operation and maintenance scenarios; the alarm level mapping rule realizes the unified conversion between manufacturer-defined alarm levels and preset standard alarm levels; the alarm location standardization mapping rule organizes fuzzy location descriptions into a hierarchical standard format of node-data center-rack-device-port.

[0031] In this embodiment, step S5 performs field completion and normalization mapping on the parsing results. Field completion includes: for cases where the device location is missing or the component name is abbreviated in the parsing results, the QKD device basic information database is queried based on the device's unique number to automatically complete information such as standard installation location, server room cabinet level, and device affiliation, thus perfecting the corresponding field content. Normalization mapping includes: according to the preset QKD alarm standardization mapping rules, synonymous alarm content from different sources and with different expressions is uniformly converted and converged into a standard expression to ensure the consistency of all records.

[0032] In this embodiment, step S6 involves storing standardized alarm records that conform to the standardized alarm template in a database for subsequent querying, statistical analysis, fault location, and accumulation of maintenance experience. Manually entered maintenance alarm data can also serve as a supplement and verification basis for automated equipment alarm data, thereby improving the completeness and accuracy of alarm data.
