[0003] Currently, the synthesis of information tables of multi-station-end monitoring systems, network shutdown devices, and centralized control main stations mostly adopts the method of manual modification. However, due to the large number of point numbers in the information table, it takes a long time and the operation and maintenance personnel face huge pressure and heavy tasks. Therefore, how to efficiently realize the integration of these information point tables has become an urgent problem to be solved. Summary of the Invention

[0004] In order to realize the automatic integration of power-related information point tables and improve work efficiency, this application provides a method and system for realizing the integration of four meters of power monitoring signals.

[0005] In a first aspect, this application provides a method for realizing the integration of four meters of power monitoring signals, including the following steps: obtaining the local system information point table, the main station system information point table, the data network shutdown point table, and the station-end monitoring background point table;

[0006] Parsing the local system information point table, the main station system information point table, the data network shutdown point table, and the station-end monitoring background point table; performing integration processing; the integration processing includes: using the point number of the local system information point table as the key index, matching and merging the local system information point table with the main station system information point table, the data network shutdown point table, and the station-end monitoring background point table, and outputting the integrated point table as the standardized information point table.

[0007] By adopting the above solution, by obtaining and parsing the information point tables of the main station system, the data network shutdown device, and the station-end monitoring background, based on the local system information point table, and using the point number of the local system information point table as the unique identifier for indexing, the integration with the other three tables is completed, realizing the standardization of the information point table, improving the unified understanding of the monitoring signals, and reducing work troubles.

[0008] Preferably, the process of fusing the local system information point table with the data network shutdown point table further includes: obtaining the rcd file of the data network shutdown, searching for the content of the merged calculation generated quantity in the rcd file of the data network shutdown, and searching for the signals participating in the merger according to the measurement expression in the found content of the merged calculation generated quantity, and matching them with the local system information table.

[0009] By adopting the above solution, considering that there are operation processes of merging signals from different sources or multiple channels during the transmission of the data network shutdown, based on the rcd file parsing, such information is searched for signals and matched with the local system information table to achieve more accurate table fusion.

[0010] Preferably, the process of fusing the local system information point table with the station-side monitoring background point table further includes: performing information matching according to the consistency of the IEC61850 path name of the synthesized signal in the local system information point table.

[0011] By adopting the above solution, in addition to the dot as the only identifier, the IEC61850 path consistency is used for information matching of the synthesized signal, which improves the accuracy of information matching.

[0014] By adopting the above solution, considering that problems such as incorrect names, incorrect paths, misplaced point numbers, and incorrect signal quantities may occur during the information matching process based on the information in the local system information point table, warning information prompts are generated correspondingly for the problematic information to facilitate timely correction.

[0015] Preferably, the process of fusing the local system information point table with the master station system information point table or the station-side monitoring background point table further includes:

[0017] Using natural language processing technology or machine learning recognition technology, taking the point number in the local system information point table as the key index, compare and analyze whether the corresponding point number sets limits for the telemetry signal, the interval to which the telemetry signal belongs, and the coefficient of the telemetry signal in the master station system information point table or the station - side monitoring background point table and the local system information point table respectively, and generate an alarm prompt for the inconsistent situations of whether the limits are set, the belonging interval, and the coefficient.

[0018] By adopting the above - mentioned scheme, considering that based on the information in the local system information point table, during the information matching process, there may be inconsistent situations between the content of the telemetry signal and the telemetry signal to be merged, and corresponding warning information prompts are generated to improve the accuracy of the data in the information table.

[0019] Preferably, it further includes:

[0020] Before outputting the fused point table as the standardized information point table, display the output fused point table on the artificial terminal through a visual verification interface.

[0021] After obtaining the verification confirmation triggered based on the visual interface, use the fused information point table as the standardized information point table or obtain the point table after manual adjustment based on the visual interface, and use the adjusted point table as the standardized information point table.

[0022] By adopting the above - mentioned scheme, a visual interface is designed to facilitate manual further review of the fused content, and timely correct the mismatched or suspected error signals to ensure the correctness of the standardized information point table.

[0023] Preferably, it further includes: when obtaining the local system information point table, the master station system information point table, the data network gateway point table, and the station - side monitoring background point table, record and store the versions of each point table simultaneously.

[0024] By adopting the above - mentioned scheme, the version information of each point table is recorded, making the version history traceable and further improving the convenience of management.

[0029] By adopting the above solution, based on the local system information point table and fusing it with the other three tables, the standardization of the information point table is achieved, thereby greatly improving work efficiency and reducing the pressure and workload of operation and maintenance personnel.

[0038] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] As Figure 1 shown, an embodiment of the present application discloses an implementation method for the four-meter integration of power monitoring signals, and the specific steps are as follows:

[0040] S1. Obtain the local system information point table, the master station system information point table, the data network gateway point table, and the substation monitoring background point table.

[0041] Obtain the local system information point table, generate call commands for each point table through the local system, obtain the master station system information point table, the data network gateway point table, and the substation monitoring background point table correspondingly, and record and store the versions of each point table at the same time, so that in subsequent version updates or changes, historical traceability can be conveniently carried out, improving the convenience of management.

[0042] Specifically, taking a substation system as an example, the substation system generates a call command for the substation monitoring background point table. The command includes the transformation station ID and is transmitted to Zone I in the form of a file through reverse isolation. The front-end point table call background server in Zone I parses and calls the substation monitoring background point table file. The successfully called point table file is stored in the specified directory of the server. The master station system information point table and the data network gateway point table are called in the same way, and the three point table files are transmitted to the specified directory in Zone IV through forward isolation. At the same time, the files already sent by the local system are stored in the backup folder classified by substation.

[0043] S2. Parse the local system information point table, the master station system information point table, the data network gateway point table, and the substation monitoring background point table.

[0044] Specifically, read the information contained in each point table and perform parsing operations. The parsing operations include data cleaning, data conversion, and data standardization, etc.

[0045] Among them, reading the information of the local system information point table includes: point number, device information, such as: device basic information (device name), device status information (switch closed state, disconnecting switch closed state), etc., measurement point information, such as: basic attributes and characteristic signal information of measurement points such as temperature, pressure, voltage, frequency, etc., control information, such as execution status and feedback information of control commands such as remote control and remote adjustment, data processing information, communication information, alarm and event information, etc.; reading the information of the master station system information point table includes: point number, device information, measurement point information, control information, alarm and event information, data processing information, communication information, etc.; reading the information of the data network gateway point table includes: point number, measurement point information, data processing information, communication information, etc.; reading the information of the station-side monitoring background point table includes: point number, device information, measurement point information, control information, alarm and event information, etc.; among them, each point number in each point table serves as the unique identifier of the information point, playing the role of identifying, positioning, and associating devices. The information point can be device status, measurement value, control command, etc.

[0046] S3. Integrate the local system information point table with the master station system information point table.

[0047] Based on the local system information point table, integrate the local system information point table with the master station system information point table. During the integration process, using the point number of the local system information point table as the key index, match and merge the information of the local system information point table and the master station system information point table, and merge the matched information. Among them, information matching can be completed based on natural language processing technology and machine learning technology.

[0048] For example: Using the point number "V_SENSOR_1" in the local system information point table, which is the unique identifier of sensor 1 for measuring voltage, as the index, obtain the information of the sensor for measuring voltage corresponding to the same point number in the master station system information point table (such as: real-time voltage data, timestamp, and device status information), and match and merge the information of the two sensors for measuring voltage.

[0049] S4. Integrate the local system information point table with the data network gateway point table.

[0050] In the same way as the above integration method, based on the local system information point table, integrate the local system information point table with the data network gateway point table. During the integration process, using the point number as the unique identifier, find and match the corresponding information, and merge the matched information.

[0051] In addition, considering that there are operation processes of merging signals from different sources or multiple channels during the transmission of the network gateway, in order to achieve more accurate table integration, it is necessary to query this type of information and match it with the local system information table, specifically including:

[0052] Obtain the rcd file of the data network gateway; specifically, as Figure 2 shown, upload the rcd file reading request of the data network gateway, the data network gateway reading request, generate a read rcd file confirmation instruction, and complete the transmission of the rcd file from the first frame to the last frame of the rcd file.

[0053] The file communication transmission in the information point table is implemented using the 104 extended type identifier 56. The definition of some frame formats is shown in Table 1:

[0054] Table 1

[0055]

[0056]

[0057] Query the content of the <merged calculation generated quantity> part in the rcd file of the data network gateway. The information in this part is all merged signals. There is an expression in this type. Through this expression, search for the signals participating in the merge in the <merged calculation participating quantity information>.

[0058] For example: "The oil level of the main transformer No. 2 body is abnormal" is a merged signal. The expression query found for it is "OP1|OP2", which means that it merges the two signals OP1 and OP2 in the <merged calculation participating quantity information>. | represents the logical OR relationship, that is, the merge relationship of the merged signal. By extracting the merged signal logic, match it with the signals in the local information table.

[0059] S5. Integrate the local system information point table with the substation monitoring background point table.

[0060] In the same way as the above integration method, based on the local system information point table, integrate the local system information point table with the substation monitoring background point table. During the integration process, use the point number as the unique identifier to find and match the corresponding information, and merge the matched information.

[0061] In addition, considering that in addition to the point number as the unique identifier, for the synthetic signal, use the IEC61850 path consistency for information matching to improve the accuracy of information matching. Specifically, it includes:

[0062] Perform information matching according to the IEC61850 path name consistency of the synthetic signal in the local system information point table. For example: Based on the IEC61850 path name of the synthetic signal in the local system information point table, this path name is used as the unique identifier of the synthetic signal, and query the signal corresponding to the same path name in the substation monitoring background point table, and the two signals with path consistency can be matched.

[0063] S6. Output the integrated point table and use it as the standardized information point table.

[0064] Store the fused point table as a standardized version, and design a visualization interface to display the fused point table, providing a standardized object for the subsequent verification of the other three tables.

[0065] In addition, to further ensure the accuracy of the fused point table, manual review and adjustment can be performed to obtain the final information point table and use it as the standardized information point table, including:

[0066] Before outputting the fused point table and using it as the standardized information point table, display the output fused point table on the manual terminal through a visualization verification interface; after obtaining the verification confirmation triggered by the reviewer based on the visualization interface, output the point table after verification confirmation, that is, the fused point table as the standardized information point table, or obtain the adjusted point table output by the reviewer after manual adjustment based on the visualization interface, and use it as the standardized information point table.

[0067] Before outputting the fused point table and using it as the standardized information point table, the output fused point table can also be sequentially displayed on multiple manual terminals in a preset order through a visualization verification interface, and obtain the fused point table output after multiple verifications or adjustments by multiple reviewers as the standardized information point table.

[0068] In a specific embodiment, during the fusion process, to further ensure the accuracy of the fusion and avoid incorrect information in some point tables leading to incorrect fusion information, the method further includes:

[0069] During the fusion process described in steps S3 and S5, it further includes:

[0070] Using natural language processing technology or machine learning technology, compare and analyze the information of the corresponding point number found with the key index of the point number in the local system information point table in the master station system information point table or the substation monitoring background point table with the information in the local system information point table; when the information can be at least one of the signal name, IEC61850 path name, point number position, and signal quantity, generate an alarm prompt for situations such as incorrect signal name, incorrect IEC61850 path name, misplaced point number, and inconsistent signal quantity.

[0071] Among them, the signal name error is based on the signal name corresponding to the point number in the local system information point table. By comparing the signal names in the master station system information point table or the station-side monitoring background point table found, if the similarity between the two is lower than the preset similarity, it is considered that there is an error in the signal name. For example: Based on the signal name "Temperature" corresponding to the point number in the local system information point table, if the similarity between it and the signal name "Temperature Value" corresponding to the same point number in the master station system information point table found meets the similarity requirement, no alarm information will be generated. If the similarity between it and the signal name "Pressure" corresponding to the same point number in the station-side monitoring background point table does not meet the similarity requirement, an alarm prompt for signal name error will be generated accordingly.

[0072] Similarly, if the similarity between the IEC61850 path names corresponding to the same point number does not meet the preset similarity, it is determined that the IEC61850 path name is incorrect, and an alarm prompt for IEC61850 path name error will be generated accordingly; if the similarity between the point number positions corresponding to the same point number does not meet the preset similarity, it is determined that the point number is misaligned, and an alarm prompt for point number misalignment will be generated accordingly; in addition, for the inconsistent number of signals corresponding to the same point number, an alarm prompt for inconsistent signal data will be generated accordingly.

[0073] The fusion processing process described in steps S3 and S5 also includes:

[0074] After fusing the signal names, taking the point number in the local system information point table as the key index, the remote signal information of the corresponding point number found in the master station system information point table or the station-side monitoring background point table and the local system information point table will be compared and analyzed respectively; the remote signal information includes whether the remote signal triggers the light sign, the interval to which the remote signal belongs, and the polarity of the remote signal; for the situations where whether the remote signal triggers the light sign, the interval to which the remote signal belongs, and the polarity of the remote signal are inconsistent, alarm prompts will be generated accordingly.

[0075] Among them, whether the light sign is triggered is displayed by the light sign status information. When the light sign status information is on, it corresponds to triggering, and when it is off, it corresponds to not triggering. By comparing the light sign status information corresponding to the same point number, once they are inconsistent, an alarm prompt for inconsistent triggering of the light sign will be generated accordingly; similarly, the interval to which each remote signal belongs is fixed and the polarity is determined. The intervals to which the remote signals corresponding to the same point number belong or the polarities should be the same. Once they are inconsistent, an alarm prompt for inconsistent interval to which the remote signal belongs or an alarm prompt for inconsistent polarity of the remote signal will be generated accordingly.

[0076] Taking the point numbers in the local system information point table as the key indexes, the corresponding point numbers found are compared and analyzed for the telemetry signal information in the master station system information point table or the substation monitoring background point table and the local system information point table respectively; the telemetry signal information includes: whether a limit value is set for the telemetry signal, the interval to which the telemetry signal belongs, and the coefficient of the telemetry signal; an alarm prompt is generated correspondingly for the situations where there are inconsistencies in whether a limit value is set for the telemetry signal, the interval to which the telemetry signal belongs, and the coefficient of the telemetry signal.

[0077] Among them, a limit value is generally set for each telemetry signal, and the set limit values of the telemetry signals corresponding to the same point number should be the same. If they are inconsistent, an alarm prompt is generated correspondingly; similarly, the interval to which each telemetry signal belongs is fixed and the coefficient is determined. The intervals to which the telemetry signals corresponding to the same point number belong or the coefficients should be the same. Once they are inconsistent, an alarm prompt for inconsistent intervals to which the telemetry signals belong or an alarm prompt for inconsistent coefficients of the telemetry signals is generated correspondingly.
