Description

Technical Field

[0001] The present invention relates to the technical field of power distribution automation, and in particular to a method for storing and managing power distribution terminal recorded data based on key information screening. Background Art

[0002] When the distribution terminal detects a line fault or abnormal operating status, it triggers the recording function to capture and store key data. This data is of great value for analyzing line faults and operating status. However, most distribution terminals currently face the problem of complicated recording start conditions and frequent triggering. In addition, their limited storage space causes the recording data to cyclically overwrite the earliest recorded data after reaching the storage limit.

[0003] Field practice experience shows that although data can be stored for about a week under normal circumstances, in extreme scenarios, the data may be overwritten within just a few hours. This requires technicians to respond quickly to ensure timely data collection and analysis. Otherwise, once the data is lost, it will hinder the in-depth analysis of faults and operating conditions. Unfortunately, due to management and technical bottlenecks, data collection is often difficult to complete in a timely manner, resulting in a large amount of valuable data loss.

[0004] To this end, it is necessary to introduce an efficient distribution terminal recording data storage and intelligent management mechanism to effectively solve the data coverage problem, ensure the persistent preservation of key recording data, and lay a solid foundation for subsequent troubleshooting and operation optimization. Summary of the invention

[0005] The present invention proposes a distribution terminal recording data storage and management method based on key information screening, which is conducive to the persistent preservation and efficient use of key recording data, and lays a solid foundation for subsequent troubleshooting and operation optimization.

[0006] The present invention adopts the following technical solutions.

[0007] A method for storing and managing distribution terminal recording data based on key information screening includes the following steps: Step S1: The power distribution terminal generates a wave recording file and integrates key information of the wave recording file into a header file for subsequent processing; Step S2: Establish a key information screening mechanism to define the importance evaluation criteria of the recording file based on the key information identified in the header file; Step S3: classify the recording files, and intelligently classify the recording files according to their importance based on the screening mechanism to achieve hierarchical management of the recording data; Step S4: Execute differentiated storage and intelligent management strategies, allocate corresponding storage space according to the importance level of the recording files, implement a circular overwriting mechanism for important recordings of the same level, and ensure that the key information of the recording files is preferentially retained and highlighted among a large amount of recording data.

[0008] The recording file is a key recording data carrier of the power distribution terminal. The recording file of the recording data includes a configuration file, a data file and a header file. The file size of the header file is much smaller than that of the data file.

[0009] The recording file of the recorded wave data includes a configuration file in a .cfg format, a data file in a .dat format, and a header file in a .hdr format.

[0010] In step S1, when the power distribution terminal detects a line fault or abnormal operating state, the wave recording function is immediately started to capture and store key data of the line condition to form a wave recording file.

[0011] In step S1, the header file records key information related to wave recording, including the triggering reason of wave recording, whether to start short-circuit fault analysis, whether to start single-phase grounding fault analysis, and the time from the last wave recording.

[0012] The time from the last recording refers to the time interval between the current recording operation and the last recording operation. This indicator is an important indicator for evaluating the frequency of recording startup of the distribution terminal; When the distribution terminal recording starts capturing events, the first recording file usually has the highest analysis value because it contains detailed information about the initial stage of the event, and the value of subsequent recordings gradually decreases. More importantly, if frequent recordings are not controlled, it is very easy to cause storage space shortages, which in turn causes important recording data to be overwritten, thereby affecting the accuracy and comprehensiveness of fault detection and operation analysis.

[0013] In step S2, the importance evaluation standard of the recording file refers to establishing a scientific importance evaluation standard for the recording file, which is used to comprehensively consider the factors of the recording triggering cause, the fault analysis startup situation and the recording time interval, and accurately define the importance level of each recording file through algorithm calculation and other methods, which serves as the basis for subsequent hierarchical classification and differentiated storage.

[0014] The detailed classification in step S3 is as follows: when the distribution terminal generates the recording file, it marks and classifies the file according to its importance level, forming a hierarchical management method to facilitate the efficiency and accuracy of subsequent data retrieval and analysis.

[0015] In step S4, the differentiated storage refers to allocating a larger storage space for the recording file containing important key information to ensure that it is not overwritten before the storage limit of the recording file is reached.

[0016] In step S4, the intelligent management strategy means that, for recording files of different importance levels, recording files of lower importance will not overwrite recording files of higher importance; for recording files of the same level, a cyclic overwriting mechanism is implemented to give priority to overwriting the recording files with the earliest generation time, so as to extend the overall storage time of the recording file data.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1) Accurately evaluate the importance of recorded data: Through the key information recorded in the header file, the importance of recorded data can be qualitatively or quantitatively evaluated. This not only improves the accuracy and efficiency of data processing, but also makes it easier for technicians to quickly screen out the most important information for analysis.

[0018] 2) Persistent preservation of key recording data: Differentiated storage and intelligent management strategies effectively solve the problem of data coverage and ensure the long-term preservation of key recording data. This provides technicians with more time windows for data collection and analysis, laying a solid foundation for subsequent troubleshooting and operation optimization. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments: Attached Figure 1 It is a schematic diagram of the overall logic block of an embodiment of the present invention; Attached Figure 2 It is a schematic diagram of a block diagram for implementing a differentiated storage and intelligent management strategy for recorded data according to an embodiment of the present invention. DETAILED DESCRIPTION

[0020] As shown in the figure, the distribution terminal recording data storage and management method based on key information screening includes the following steps: Step S1: The power distribution terminal generates a wave recording file and integrates key information of the wave recording file into a header file for subsequent processing; Step S2: Establish a key information screening mechanism to define the importance evaluation criteria of the recording file based on the key information identified in the header file; Step S3: classify the recording files, and intelligently classify the recording files according to their importance based on the screening mechanism to achieve hierarchical management of the recording data; Step S4: Execute differentiated storage and intelligent management strategies, allocate corresponding storage space according to the importance level of the recording files, implement a circular overwriting mechanism for important recordings of the same level, and ensure that the key information of the recording files is preferentially retained and highlighted among a large amount of recording data.

[0021] The recording file is a key recording data carrier of the power distribution terminal. The recording file of the recording data includes a configuration file, a data file and a header file. The file size of the header file is much smaller than that of the data file.

[0022] The recording file of the recorded wave data includes a configuration file in a .cfg format, a data file in a .dat format, and a header file in a .hdr format.

[0023] In step S1, when the power distribution terminal detects a line fault or abnormal operating state, the wave recording function is immediately started to capture and store key data of the line condition to form a wave recording file.

[0024] In step S1, the header file records key information related to wave recording, including the triggering reason of wave recording, whether to start short-circuit fault analysis, whether to start single-phase grounding fault analysis, and the time from the last wave recording.

[0025] The time from the last recording refers to the time interval between the current recording operation and the last recording operation. This indicator is an important indicator for evaluating the frequency of recording startup of the distribution terminal; When the distribution terminal recording starts capturing events, the first recording file usually has the highest analysis value because it contains detailed information about the initial stage of the event, and the value of subsequent recordings gradually decreases. More importantly, if frequent recordings are not controlled, it is very easy to cause storage space shortages, which in turn causes important recording data to be overwritten, thereby affecting the accuracy and comprehensiveness of fault detection and operation analysis.

[0026] In step S2, the importance evaluation standard of the recording file refers to establishing a scientific importance evaluation standard for the recording file, which is used to comprehensively consider the factors of the recording triggering cause, the fault analysis startup situation and the recording time interval, and accurately define the importance level of each recording file through algorithm calculation and other methods, which serves as the basis for subsequent hierarchical classification and differentiated storage.

[0027] The detailed classification in step S3 is as follows: when the distribution terminal generates the recording file, it marks and classifies the file according to its importance level, forming a hierarchical management method to facilitate the efficiency and accuracy of subsequent data retrieval and analysis.

[0028] In step S4, the differentiated storage refers to allocating a larger storage space for the recording file containing important key information to ensure that it is not overwritten before the storage limit of the recording file is reached.

[0029] In step S4, the intelligent management strategy means that, for recording files of different importance levels, recording files of lower importance will not overwrite recording files of higher importance; for recording files of the same level, a cyclic overwriting mechanism is implemented to give priority to overwriting the recording files with the earliest generation time, so as to extend the overall storage time of the recording file data.

[0030] Example: This embodiment provides a method for efficient storage and intelligent management of distribution terminal recording data based on key information screening. The adoption of this method is conducive to the persistent preservation and efficient use of key recording data, laying a solid foundation for subsequent troubleshooting and operation optimization.

[0031] To achieve the above purpose, Figure 1 As shown, this example provides a method for efficient storage and intelligent management of distribution terminal recording data based on key information screening. By integrating the generation of distribution terminal recording data, key information extraction, importance evaluation, grading and classification, differentiated storage and intelligent management, a complete recording data processing system is constructed. The core of this method is to use header files (.hdr) to record key information, realize accurate screening and efficient management of recording data, thereby effectively avoiding data overwriting and ensuring the long-term preservation of key information. It includes the following steps: Step S1, wave recording file generation and key information integration, when the power distribution terminal detects a line fault or abnormal operation state, the wave recording function is immediately started to capture and store key data to form a wave recording file.

[0032] Furthermore, the recording file, as a key data carrier, usually records core operating data such as line voltage and current instantaneous amplitude. In the storage system of traditional power distribution terminals, the recording data is mainly composed of .cfg files (configuration files) and .dat files (data files). On this basis, this method introduces .hdr files (header files) as a new component, aiming to centrally integrate and identify the key information of the recording data, so as to facilitate and improve the efficiency of subsequent processing and analysis.

[0033] Furthermore, the .hdr file (header file) refers to a file that records key information related to wave recording, including but not limited to the triggering reason of wave recording, whether to start short-circuit fault analysis, whether to start single-phase grounding fault analysis, time since the last wave recording, etc. In terms of file size, .hdr files are usually much smaller than .dat files. This feature enables technicians to collect and process key information of wave recording data more quickly and conveniently, thereby improving work efficiency and data analysis flexibility.

[0034] Furthermore, the time from the last recording refers to the time interval between this recording operation and the last recording. This indicator plays an important role in evaluating the frequency of recording startup at the distribution terminal. According to field practical experience, when recording is started too frequently, although multiple events can be captured, the first recording often has the highest analytical value because it contains detailed information at the initial stage of the event, and the value of subsequent recordings gradually decreases. More importantly, if frequent recording is not controlled, it is very easy to lead to storage space shortages, which in turn causes important recording data to be overwritten, thereby affecting the accuracy and comprehensiveness of troubleshooting and operation analysis.

[0035] Step S2: Establish a key information screening mechanism, and accurately define the importance evaluation criteria of the recording file based on the key information identified in the header file.

[0036] Furthermore, the importance evaluation standard of the recording file refers to establishing a set of scientific evaluation standards for the importance of recording files. This standard comprehensively considers factors such as the recording triggering cause, the fault analysis startup situation, and the recording time interval, and accurately defines the importance level of each recording file through algorithm calculation and other methods. This process is the basis for subsequent classification and differentiated storage.

[0037] Step S3: classify the recording files by level. Based on the screening mechanism, intelligently classify the recording files by importance to achieve hierarchical management of the recording data.

[0038] Furthermore, the fine classification means that the distribution terminal marks and classifies the recording files according to their importance level while generating the recording files. This hierarchical management method helps to make the subsequent data retrieval and analysis work more efficient and accurate.

[0039] Step S4: Differentiated storage and intelligent management strategies are used to allocate corresponding storage space according to the importance level of the recording files, and a circular overwriting mechanism is implemented for important recordings of the same level to ensure that key recording information is retained and highlighted in the massive data.

[0040] Furthermore, the differentiated storage refers to allocating a larger storage space for important recordings to ensure that they are not easily overwritten before the storage limit is reached.

[0041] Furthermore, the intelligent management strategy means that, for recording files of different levels, recording files of lower importance will not overwrite recording files of higher importance; for recording files of the same level, a cyclic overwriting mechanism is implemented to give priority to overwriting the recording files with the earliest generation time, so as to extend the overall data storage time.
