[0046] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with 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.

[0047] In the related technologies, the power grid operation intelligent system is composed of master station systems and plant station systems at the network, province, prefecture (county, distribution) levels. Each master station / plant station system is divided into five parts: Basic Resource Platform (BRP), Operation Control System (OCS), Operation Management System (OMS), Power System Operation Cockpit (POC) or Substation Operation Cockpit (SOC), Mirror Test Training System (MTT). The system follows the Service-Oriented Architecture (SOA) system, builds an integrated support platform and operation service bus (OSB) based on a unified information and communication technology infrastructure and unified model and service interface standards. Various business functions are constructed or improved based on this. The functional modules / business subsystems in the master stations / plant stations at all levels are integrated through the support platform and the horizontal operation service bus, and the interconnection with the upper and lower related business systems is realized through the vertical operation service bus. The system realizes information sharing, coordinated control and process management with other relevant business systems through the OSB standard service interface.

[0048] For power systems with numerous equipment, wide coverage and large capacity, the control method of stratification by voltage level and then by region is adopted under the unified command of the highest-level control center. The power system operation control includes operation control and its automation under normal operation and operation control and its automation under accident conditions. According to the secondary system safety protection requirements, the various functions of the system are deployed in safety zone I, safety zone II and safety zone III according to application needs. Among them, safety zone I and safety zone II mainly include data acquisition and exchange function group and application function group; safety zone III mainly includes data acquisition and exchange function group, application function group, WEB service and mobile terminal service.

[0049] At present, different areas in the power system need to exchange data across regions. During the communication process, due to the mutation of data traffic and unreasonable distribution, the direct transmission of a large amount of data can easily cause congestion, communication interruption, low efficiency and other problems, which is not conducive to timely feedback of safety issues in the power system, resources cannot be used reasonably, network performance is reduced, and service quality cannot be guaranteed.

[0050] Based on this, an embodiment of the present application proposes a message subscription mechanism cross-region service message push method, device, computer equipment and storage medium, wherein the message subscription mechanism cross-region service message push method includes: by obtaining the message of the local service cluster, the message is placed in the message queue; and by obtaining the subscription information of different areas of the power grid, the target application unit corresponding to the subscription corresponding message is obtained according to the subscription information, and then the message in the message queue is retrieved, and the message is pushed to the corresponding target application unit, and the message is stored in the message queue, and the message is retrieved from the message queue for pushing, so as to avoid the problem of congestion caused by sending a large amount of data at the same time, effectively improve the response efficiency of cross-region service messages, and facilitate the application unit to obtain the push message of the power system in time, and the real-time and security are guaranteed, which is conducive to improving the quality of user service.

[0051] In one embodiment, Figure 1 As shown in FIG. 1 , it is a schematic diagram of the architecture of the power grid operation control system. The power grid operation control system includes a human-machine interface 100, a data center 200, and a data acquisition and exchange 300. Among them, the human-machine interface 100 includes a control operation module, a power grid operation monitoring module, a graph model maintenance module, an event monitoring module, and a front-end monitoring and debugging module. The data center 200 includes a real-time library, a relationship library, a timing library, and an object storage library. The data acquisition and exchange 300 includes a control service cluster, a data service cluster, a model service cluster, a file service cluster, a data acquisition and monitoring control SCADA processing cluster, and a front-end service cluster. The specific data flow architecture of the operation control system is shown in FIG. Figure 1It can be understood that the message is obtained through the SCADA processing cluster, and the message obtained by the SCADA processing cluster is placed in the message queue, and the corresponding message is retrieved from the message queue according to the subscription information, so as to push the message to the corresponding application unit, thereby completing the push of cross-region service messages, realizing real-time transmission of data, having high real-time performance and security, and ensuring high service quality.

[0052] In one embodiment, Figure 2 As shown, a message subscription mechanism cross-region service message push method is provided, which is applied to the above-mentioned power grid operation control system, and the method includes the following steps:

[0053] Step S202: collect messages from the local service cluster and form a message queue.

[0054] In this step, the messages of the local service cluster may include various events generated by the service clusters in the operation control system, such as master station alarm messages, etc. The operation control system collects data from each service cluster through the SCADA processing cluster, and the data is temporarily stored in the message queue in the form of messages. The message queue is an important component in the distributed system and can meet the requirements of cross-region service message push. It has the advantages of improving system performance, peak shaving, and reducing system coupling.

[0055] More specifically, a data collection and monitoring control system may be used to collect data from the local service cluster to obtain the message.

[0056] Step S204, obtaining subscription information of different areas of the power grid, and determining a target application unit for subscription messages according to the subscription information.

[0057] In this step, by obtaining subscription messages from different areas of the power grid, it can be understood that the message has a sender and a receiver. The receiver of the message subscribes according to the message type to realize the subscription and release of the message. The sender and receiver of the message can be multiple. The message content subscribed by the receiver of the message is the subscription information. Therefore, according to the subscription information, the application unit corresponding to the subscription to the corresponding message can be obtained, that is, the receiver of the message can be determined according to the message content. The application unit can be understood as the carrier corresponding to the receiver, which can be an application, SMS, email, etc.

[0058] Step S206, retrieve the message in the message queue and push the message to the target application unit.

[0059] In this step, after obtaining the corresponding application unit, the corresponding message is retrieved from the message queue, and the message is pushed to the corresponding target application unit, thereby completing the push of the cross-region service message.

[0060] In one embodiment, a message queue is used to temporarily store messages, and messages are retrieved from the message queue for push. A virtual memory is used as an example for explanation as a storage unit of the message queue. Messages are stored in the virtual memory. The virtual memory has an independent application function and can store different message types. Messages are only stored in the virtual memory and do not occupy local storage in each area. This enables unified management of resources and avoids congestion caused by sending large amounts of data. It also accelerates the response speed of messages and effectively improves the transmission efficiency of cross-region service messages, which is beneficial for users to obtain push messages from the power system in a timely manner. Real-time and security are guaranteed, which is beneficial for improving user service quality.

[0061] It should be noted that the above steps S202 to S206 are implemented based on the data flow architecture of the power grid operation control system. Various types of steady-state, dynamic, protection, video and other data collected by the front-end operating environment directly enter various monitoring function modules such as steady-state monitoring, dynamic monitoring, protection operation monitoring, video and environmental monitoring through the message bus. In this way, the function module provides the data it needs to send to the data integration and service functions of the data center 200 through the message bus for unified management and external release; various types of data that need to be stored and accessed in relational databases and time series databases are uniformly provided to the outside by the database support platform services of the data center 200; the message queue uses the message bus as the transmission carrier to realize unified management of messages.

[0062] In the cross-region service message push method of the above-mentioned message subscription mechanism, the message is placed in the message queue by obtaining the message of the local service cluster; and by obtaining the subscription information of different areas of the power grid, the target application unit corresponding to the subscription message is obtained according to the subscription information, and then the message in the message queue is retrieved and pushed to the corresponding target application unit. The message is stored in the message queue, and the message is retrieved from the message queue for pushing, so as to avoid the problem of congestion caused by sending a large amount of data at the same time, effectively improve the response efficiency of cross-region service messages, and facilitate the application unit to obtain the push message of the power system in time, so that the real-time and security are guaranteed, which is conducive to improving the quality of user service.

[0063] In one embodiment, the above step S202 specifically includes: determining the type of the message; and storing the message in data partitions according to the type of the message to form a message queue.

[0064] In this embodiment, message types have different classifications, and general messages are subscribed according to the classification, and messages of multiple categories can be subscribed at the same time. Before a message is placed in a message queue, the type of the message is first determined, and then data partition storage is performed according to the type of the message, that is, different types of messages are stored in different data partitions, thereby forming a message queue. The message queue is a data queue, and the use of partitioned storage for messages is conducive to speeding up the reading speed of messages and improving the response efficiency of messages. For example, when the data of the main station fault is obtained, the main station fault data is stored in the front storage partition of the message queue. Through the front storage partition, the message can be quickly retrieved and pushed to the corresponding recipient. It can be understood that the fault type data is stored as an emergency message using a data partition method, and the emergency message is read and written first, so that the emergency message can be processed first, effectively improving the response efficiency of the message, and facilitating the rapid processing of fault events.

[0065] In one embodiment, Figure 3 As shown, the specific process of the message subscription mechanism cross-zone service message push method includes the following steps:

[0066] Step S302, determining the type of the message;

[0067] Step S304, storing the messages in data partitions according to the message types to form a message queue;

[0068] Step S306, obtaining subscription information of different areas of the power grid, and determining a target application unit for subscription messages according to the subscription information;

[0069] Step S308, retrieve the message in the message queue and push the message to the target application unit.

[0070] Furthermore, in one embodiment, the message includes the time when the event occurred, the name of the subject of the event and the classification identifier of the event; the above step S304 also includes: according to the level of the event, the message is prioritized to form a message queue.

[0071] It is understandable that the type of message is defined according to actual requirements. The various events generated by each service cluster in the power grid operation control system may include information such as the time when the event occurred, the name of the subject of the event, and the classification identification of the event. The above information can be used to define the event, which is convenient for generating messages, that is, the message at least includes the time when the event occurred, the name of the subject of the event, and the classification identification of the event. Of course, different types of messages can also add other required information, such as the node name and device name of the computer and network device status report message, which will not be described in detail.

[0072] In addition, the level of an event can be understood as the classification of an event based on information such as the time of occurrence of the event, the name of the subject of the event, and the classification identification of the event. It can be understood that events involving the failure safety of the power grid system can be defined as higher-level messages. The higher the level of the event, the higher the urgency. In this way, messages can be prioritized according to the level of the event. The higher the level of the event, the higher the priority of the message corresponding to the event, and the more urgent it needs to be pushed, so as to speed up the handling of emergency events.

[0073] In one embodiment, Figure 4 As shown, the message subscription mechanism cross-zone service message push method includes the following steps:

[0074] Step S402, arranging the messages by priority according to the level of the event to form a message queue;

[0075] Step S404, obtaining subscription information of different areas of the power grid, and determining the target application unit of the subscription message according to the subscription information;

[0076] Step S406, retrieve the message in the message queue and push the message to the target application unit.

[0077] It can be understood that by arranging the priorities of messages to form a message queue, messages with higher priorities can be arranged in the front position of the message queue. When retrieving messages, information is retrieved from the front position and pushed first, thereby pushing messages according to the urgency of the event, effectively improving the response efficiency of messages, and preventing messages from conflicting with each other and causing congestion. The transmission efficiency of cross-regional service messages is effectively improved, which is conducive to timely handling of emergencies, ensuring real-time and security, and helping to improve user service quality.

[0078] In this embodiment, the data acquisition and monitoring control SCADA system is used to collect data from the local service cluster. The SCADA system is a computer-based production process control and dispatching automation system. In the power system, the SCADA system can realize various functions such as data acquisition, equipment control, measurement, parameter adjustment, and various signal alarms. The specific details are not repeated here. The SCADA processing cluster obtains messages, puts the obtained messages into the message queue, and then retrieves the corresponding messages from the message queue according to the subscription information, so as to push the messages to the corresponding application units, thereby completing the push of cross-region service messages, realizing rapid data transmission, and ensuring real-time and security, and ensuring high user service quality.

[0079] It should be noted that the message queue can be understood as a unified shared resource pool built through certain normative constraints. Through virtualization technology, it is divided into storage arrays that can be flexibly configured and dynamically adjusted, which can realize dynamic allocation of resources on demand. When storing messages, resource competition should be avoided during planning. For example, the memory access of the message queue may be inconsistent or discontinuous. The data sorting mechanism is used to aggregate and disperse the stored data, so that the data can be sorted in the form of an array, and the array can be stored in a dispersed manner. Based on the dispersed allocation strategy of the array, resource competition can be effectively avoided when creating a message queue.

[0080] It is understandable that when the message queue is not used, the user's request data is directly written to the database. In the case of high concurrency, the database pressure increases dramatically, which slows down the response speed. By using the message queue to store messages, when a request to retrieve a message is sent to the message queue, the corresponding data is obtained from the message queue and pushed to the corresponding application unit. Since the storage array processing speed of the message queue is faster than that of the database, the response efficiency of the message queue is high, so that the message queue has a good peak-cutting function, that is, through asynchronous processing, events generated by short-term high concurrency are stored in the message queue, thereby flattening the concurrent events during the peak period.

[0081] In addition, cross-region service messages are pushed through message queues. There is no direct coupling between the sender and the receiver. The sender ends the processing of the message when it sends the message to the message queue. The receiver obtains the message from the message queue for subsequent processing. As long as the receiver subscribes to messages of the corresponding type, it can receive messages from the message queue. This has no impact on the original system and business, thereby reducing system coupling.

[0082] In one embodiment, the above step S206 specifically includes: pushing a prompt according to the type of the message; and acquiring corresponding data content from the message queue according to the push prompt.

[0083] It is understandable that the message type supports different classifications, and different types of messages can be prompted by adding identifiers, so that the messages in the message queue can be retrieved and pushed according to the prompts. Specifically, considering that the message may include the time when the event occurred, the name of the subject of the event and the classification identifier of the event, the classification identifier of the event can be used to add a push prompt to the corresponding message. The push prompt is used to quickly identify the corresponding message from the message queue and retrieve it for push. For example, the higher the level of the defined event, the higher the urgency, and the higher the priority of the corresponding message. In this way, different prompts are added according to messages of different levels. The higher the priority message, the higher the level of prompts are added to facilitate priority processing, effectively improving the response efficiency of the message, and facilitating the rapid processing of emergencies.

[0084] In one embodiment, the above step S206 further includes: determining the state of the data content; when the state of the data content changes, determining whether the data content includes content of power grid security risk, and sending a notification to the local service cluster.

[0085] It is understandable that the message queue is used to store messages, and the messages are stored in the message queue in the form of data to achieve unified resource management. The message queue pushes the message to the corresponding target application unit according to the subscription information, without the need to store the message locally. In the message queue, based on the real-time nature of data interaction, the data sending node of the message queue can monitor the sending status of the data content in real time. When the status of the data content changes, it means that the event corresponding to the data content has changed.

[0086] In this embodiment, when the data content includes the content of power grid security risk, considering that the power grid system may have events involving security issues, a notification needs to be sent to the local service cluster so that the local service cluster can be informed of the message change status in a timely manner, and at the same time, the message is given a higher priority and pushed to the corresponding target application unit, so that messages involving power grid security risks can be quickly processed and the emergency response efficiency can be improved. For example, after the data corresponding to the message is written into the message queue, the event corresponding to the message is upgraded to an emergency event, such as the main station upgrades from an alarm message to a shutdown failure. At this time, the message is processed expedited and pushed to the corresponding recipient via email, SMS or application, which is conducive to the application unit to obtain the push message of the power system in a timely manner, with high real-time performance, and effectively improves the user service quality.

[0087] In one embodiment, the above step S204 specifically includes: obtaining real-time business data uploaded by the distributed subscription message system and collecting data from the data collection terminal; and searching for the recipient of the subscription message according to the real-time business data.

[0088] It is understandable that the distributed subscription message system adopts the Kafka system. Kafka is an open source stream processing platform developed by the Apache Software Foundation. It is a high-throughput distributed publish-subscribe message system that can process all action stream data of users on the website. The Kafka data channel is a data exchange channel built based on the Kafka architecture. The decoupling characteristics of Kafka can effectively ensure the transmission of data. The external business data platform refers to a business data platform used to store data generated by the business system. When the business system generates business data, these business data can be uploaded to the external business data platform through the corresponding Kafka channel. The business data platform saves the business data. When the processor receives the business demand data, it can access the external business data platform according to the business demand data to obtain the business data to be processed corresponding to the business demand data. The real-time business data uploaded by the data collection terminal is collected through the distributed subscription message system, and the target real-time business data corresponding to the business data to be processed is searched. According to the target real-time business data and the business data to be processed, the data processing result is obtained, and the data processing result can determine the recipient of the message. It can be understood that a message has a sender and a receiver. The receiver of the message subscribes according to the message type to realize the subscription and publication of the message. The message content subscribed by the receiver of the message is the subscription information. According to the subscription information, the application unit corresponding to the subscription to the corresponding message can be obtained, that is, the receiver of the message can be determined according to the message content.

[0089] In this embodiment, a message queue is used to temporarily store messages, and messages are retrieved from the message queue for push. Messages are only stored in virtual memory and do not occupy local storage in each area. This enables unified management of resources and avoids congestion caused by sending large amounts of data. It also accelerates the response speed of messages and effectively improves the transmission efficiency of cross-region service messages, which is beneficial for users to obtain push messages from the power system in a timely manner. Real-time and security are guaranteed, which is beneficial to improving user service quality.

[0090] In one embodiment, after the above step S206, the method further includes: determining the push status of the message; when the push status is push failure, calling a backup server to forward the message.

[0091] In this embodiment, a virtual memory is used as a storage unit of a message queue, and messages are stored in the virtual memory. The virtual memory can store different message types, and messages are only stored in the virtual memory, and will not occupy the local storage of each area. In order to ensure that the messages in the message queue can be sent smoothly, the operation control system allows the standby server to be used as a standby memory for the message queue. During normal operation, the message queue is used to store messages, and the standby server is in a standby state.

[0092] The data sending node through the message queue can monitor the push status of the message in real time. When the push status is a failure, the virtual storage may have a fault. At this time, the backup server is called to run, and the backup server is used to forward the message to the corresponding application unit to complete the message push, avoiding the push of cross-region service messages due to the inability of the message queue to run. The backup server does not affect the normal operation of the message queue, making resource management more flexible and convenient, ensuring security, and effectively improving user service quality.

[0093] It should be understood that although Figure 2-4 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 2-4 At least part of the steps may include multiple steps or multiple stages. These steps or stages are not necessarily performed at the same time, but can be performed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed in turn or alternately with other steps or at least part of the steps or stages in other steps.
