[0046] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0047] Example 1

[0048] Reference Figure 1-Figure 2 , is an embodiment of the present invention, and provides a master station dual-collection electric energy metering method, comprising:

[0049] S100: Acquire meter data, and transmit the meter data to the master station front-end collection message bus in a set form to obtain first meter data;

[0050] In the embodiment of the present application, the dual terminals at the plant and station end respectively collect the data of the electric energy meters at each metering point in full, and send the meter data to the front-end collection message bus of the master station in the form of a set message;

[0051] Specifically, Figure 2As shown, the main terminal collects data from the A main meter and A sub-meter at the metering point A and the B main meter and B sub-meter at the metering point B, and the sub-terminal collects data from the B main meter and B sub-meter at the metering point B and the A main meter and A sub-meter at the metering point A;

[0052] It should be noted that the dual-terminal configuration provides double protection for data and ensures the integrity of the data. Even if one terminal fails, the other terminal can still provide data, thereby improving data redundancy. The dual terminals can collect data at the same time. Compared with single-terminal collection, it can reduce waiting time and improve data collection efficiency. The dual-terminal configuration allows data collection at different metering points, which can more evenly distribute data collection tasks and optimize resource utilization.

[0053] S200: Acquire different terminal data corresponding to the first electric meter data, parse the terminal data, deliver the parsed terminal data to the dual storage service cluster, and store the terminal data in a corresponding storage module;

[0054] S300: Verify the terminal data, obtain the verification result, and perform statistical analysis on the verification result.

[0055] It should be noted that through the dual collection method of the master station with dual terminals in the plant station, the system can save two redundant data, improve the reliability and security of the data, provide mutual integrity verification of the two copies of data, ensure the integrity and accuracy of the data, and provide more reliable data support for subsequent business, realizing efficient collection and real-time transmission of electric energy data, and ensuring the timeliness of the data.

[0056] In the embodiment of the present application, the above step S200 includes the following sub-steps A1-A2;

[0057] In A1: the first master station end front cluster collects data from the main terminal, and the second master station end front cluster collects data from the secondary terminal;

[0058] In A2: the primary terminal data is stored in the primary storage, and the secondary terminal data is stored in the secondary storage.

[0059] In the embodiment of the present application, the front-end 1 cluster of the master station collects data from the main terminal, and the front-end 2 cluster collects data from the secondary terminal. Both front-ends support dual-plane network communication. The data collected by the front-end 1 cluster is stored in the main storage server, and the data collected by the front-end 2 cluster is stored in the secondary storage server.

[0060] Specifically, the terminal sends the collected meter data to the main station front-end collection message bus in the form of a message; the front-end collection service consumes the message data on the message bus and then parses it, and delivers the parsed data to the dual storage service cluster; after receiving the data, the dual storage service cluster stores the main terminal data in the main storage and the secondary terminal data in the secondary storage;

[0061] It should be noted that by storing the main terminal and sub-terminal data in the main storage and sub-storage respectively, the security of the data is enhanced. Even if one storage system fails, the other system can still maintain the integrity of the data. Even when the main storage fails, the data in the sub-storage can be used as a backup to ensure that the data will not be lost. The design of the dual storage system improves the reliability and stability of the entire electric energy metering system and ensures the continuous availability of data. Storing the main terminal and sub-terminal data separately can more effectively manage and access data and improve the efficiency of data retrieval and analysis.

[0062] In the embodiment of the present application, the above step S300 includes the following sub-steps B1-B3;

[0063] In B1: the terminal data is connected to the stream processing system, the terminal data is divided into different time windows according to the timestamp of the terminal data, and the terminal data is sorted;

[0064] In B2: for the terminal data in each time window, if the timestamps of the terminal data are not continuous, there is a data breakpoint;

[0065] In B3: If there is no data at a time point, there is a data gap.

[0066] Specifically, the terminal data is connected to the Flink stream processing system, and the data stream is divided into different time windows (such as every minute, every hour, etc.) according to the timestamp of the data. Flink provides a variety of time windows to meet different business needs. In each time window, the data is sorted according to the timestamp of the data to ensure the order of the data, which is crucial for detecting breakpoints and leaks.

[0067] For the data in each time window, check whether there is a timestamp jump. If the timestamp of the data is discontinuous, that is, there is a gap between the timestamp of the current data and the timestamp of the previous data, it indicates that there is a data breakpoint.

[0068] Check whether the data in the time window covers the entire time range. If there is no data at a certain time point, it indicates that there is a data leak. Once a breakpoint or leak is found, mark these anomalies in the data stream so that subsequent processing can identify and handle these anomalies.

[0069] It should be noted that by detecting data breakpoints and leaks, the continuity and integrity of time series data are ensured, thereby improving the accuracy of the data. Identifying and marking breakpoints and leaks in the data helps with subsequent data completion and correction, enhancing data integrity. The Flink stream processing system is used to process data in real time, optimize the data processing process, improve data processing efficiency, detect data breakpoints and leaks in real time, respond quickly to data anomalies, and improve the system's processing speed for data problems.

[0070] In the embodiment of the present application, after completing steps B1-B3 in the above step S300, the following steps B4-B5 are also included;

[0071] In B4: search for the corresponding data points in the secondary storage for the data points missing from the primary storage. If the data points can be found, pull the data to the primary storage.

[0072] In B5: the data points missing from the secondary storage are searched for corresponding data points in the primary storage. If the data points can be found, the data are pulled to the secondary storage.

[0073] Specifically, the data points missing from the primary storage are searched for corresponding data points in the secondary storage. If they can be found, the data is pulled to the primary storage as a means of completing the integrity of the primary storage data. Similarly, the data bidirectional consistency service searches for corresponding data points missing from the secondary storage in the primary storage. If they can be found, the data is pulled to the secondary storage. Finally, the goal of data consistency between the primary and secondary storages is achieved, which also maximizes data integrity.

[0074] Specifically, in order to achieve the dual-collection purpose of the main station of the dual-terminal plant station, the application layer must also provide collection measurement model management to realize the preparation of the dual-terminal and dual-channel collection archive layer. The collection archive is newly added on the basis of the original single terminal and single channel of the system, and the main and secondary marks of the terminal and channel are recorded in the archive layer. Finally, the main station side provides verification and consistency analysis services to realize the statistical analysis of verification results, evaluation of dual-terminal uploaded data, statistical analysis of bidirectional data pull, and summary of dual-terminal redundant results.

[0075] It should be noted that by searching and pulling missing data points between the primary and secondary storages, data is completed to the maximum extent, data integrity is improved, and consistency of primary and secondary storage data is achieved, ensuring that data collected from the two channels have the same reliability in the final application. When data is missing in either the primary storage or the secondary storage, the system can recover it through the data in the other storage, thereby enhancing the fault tolerance of the system. The two-way data pulling mechanism provides an effective means of data backup and recovery, simplifies the data recovery process, and even in the event of partial data loss, the system can maintain continuous business operation through complementary data.

[0076] The above is a schematic scheme of a master station dual-collection electric energy metering method of this embodiment. It should be noted that the technical scheme of the master station dual-collection electric energy metering system and the technical scheme of the master station dual-collection electric energy metering method described above belong to the same concept. For details not described in detail in the technical scheme of the master station dual-collection electric energy metering system in this embodiment, please refer to the description of the technical scheme of the master station dual-collection electric energy metering method described above.

[0077] The master station dual-collection electric energy metering system in this embodiment includes: a collection and metering archive module, a dual collection module, a terminal collection task module, a dual storage module, a dual storage module, a primary and secondary storage data verification module, a data bidirectional consistency module, and a verification and consistency analysis module;

[0078] The acquisition and metering archive module is used to associate the collected data with specific terminals, channels, collection points and meters;

[0079] The dual acquisition module is used to build a dual acquisition service cluster at the main station;

[0080] The terminal collection task module is used to allocate the main terminal collection task, main terminal file, and main channel file to the main front-end cluster, and allocate the secondary terminal collection task, secondary terminal file, and secondary channel file to the secondary front-end cluster;

[0081] The dual storage module is used to build a dual storage service cluster at the main station;

[0082] Dual storage modules are used to build dual storage service clusters at the main site

[0083] The primary and secondary storage data verification modules are used to find the breakpoints and leakage data of the primary and secondary storages respectively;

[0084] The data bidirectional consistency module is used to complement the breakpoint and leakage data in both directions;

[0085] The verification and consistency analysis module is used to perform statistical analysis on the verification results of the primary and secondary storage data verification modules.

[0086] Specifically, one collection cluster in the dual collection module is responsible for main terminal data collection, and the other collection cluster is responsible for secondary terminal data collection;

[0087] The collection tasks in the terminal collection task module include automatic collection and manual collection. The collection tasks issued by the page are sent to the terminal collection task management service;

[0088] In the dual storage module, the primary storage cluster is responsible for the primary terminal data storage, and the secondary storage cluster is responsible for the secondary terminal data storage;

[0089] The dual storage module stores the original terminal data collected by the collection service cluster. The primary storage is responsible for storing the original data of the primary terminal, and the secondary storage is responsible for storing the original data of the secondary terminal.

[0090] Breakpoints and leaks are found in the primary and secondary storage data verification modules, and the discovery records are kept;

[0091] In the data bidirectional consistency module, the breakpoint and leakage data are complemented bidirectionally to maximize the integrity of the primary and secondary storage data and retain the data operation record information;

[0092] In the verification and consistency analysis module, the verification results of the primary and secondary storage data verification services are further statistically analyzed, and the data sent by the dual terminals are evaluated; the bidirectional data pull involved in the data bidirectional consistency service is statistically analyzed, and the dual terminal redundancy results are summarized.

[0093] It should be noted that the dual-terminal dual-collection data collection method significantly improves the security, real-time and accuracy of data collection compared to the single-terminal single-collection method. Under the single-terminal collection method, once a data collection leak or breakpoint occurs, it usually relies on the subsequent batch of data collection or manual intervention. In contrast, the dual-terminal dual-collection method can complement each other in the case of data leaks or breakpoints through mutual hot backup and bilateral data verification at the data consistency layer, thereby improving the reliability of data collection. In addition, bilateral data verification can also effectively detect abnormal changes in electricity meter data to ensure the high accuracy and consistency of collected data. At the same time, dual data storage not only improves data security, but also provides redundant protection, avoids data loss caused by single storage failure, and facilitates data recovery and analysis, enhancing the disaster recovery and resistance capabilities of the electric energy metering system.

[0094] In the embodiment of the present application, the collection and measurement archive module includes a terminal archive module, a channel archive module, a collection point archive module and an electric meter archive module;

[0095] In the terminal file module, the primary and secondary terminal files are stored separately;

[0096] The main and sub-channel files are stored separately in the channel file module.

[0097] The collection points in the collection point archive module serve as logical collection units and correspond to those within the factory;

[0098] The meter files in the meter file module correspond one-to-one to the physical meters at the plant end.

[0099] Specifically, in the terminal file module, the main terminal is stored in the main terminal file table, and the secondary terminal is stored in the secondary terminal file table;

[0100] In the channel archive module, the main channel is stored in the main channel archive table, and the secondary channel is stored in the secondary channel archive table;

[0101] In the collection point archive module, the primary and secondary collection terminals of the same plant station are mounted on the same collection point;

[0102] In the meter file module, there is only one meter file for the same meter;

[0103] It should be noted that through modular data management, electric energy metering data can be organized and retrieved more efficiently, which improves the efficiency of data management. The separate storage of the main and secondary terminals and channel archives helps to maintain data consistency and facilitates monitoring and comparison of data differences between the main and secondary channels. The one-to-one correspondence between the meter archives and the physical meters at the plant and station end ensures the accuracy of the data and facilitates tracking and verification of the data source. The collection point, as a logical collection unit, corresponds to the plant and station, which helps to optimize the allocation and management of data collection resources.

[0104] In the embodiment of the present application, the electric meter interacts with the primary and secondary terminals through the communication port, and the communication protocol is the first protocol.

[0105] Specifically, the electric meter interacts with the main terminal and the auxiliary terminal through the 485 communication port, and the communication protocol is the 645 protocol;

[0106] It should be noted that the combination of RS-485 interface and 645 protocol supports a variety of electricity meters and terminal devices, improving the compatibility of the system. RS-485 supports multi-point communication, allowing multiple electricity meters to be connected to the same bus, reducing wiring requirements and simplifying the system architecture.

[0107] This embodiment also provides a computing device, which is applicable to the dual-collection electric energy metering of the master station, including:

[0110] The storage medium proposed in this embodiment and the method for realizing dual-collection electric energy metering of the master station proposed in the above embodiment belong to the same inventive concept. The technical details not fully described in this embodiment can be referred to the above embodiment, and this embodiment has the same beneficial effects as the above embodiment.
