Description

Technical Field

[0001] The present application relates to the field of power system protocol message transmission, and in particular to a message transmission method, system, device, storage medium and computer program product. Background Art

[0002] During the operation and control of the power system, different devices will exchange information by transmitting messages. And the messages in the information exchange process must comply with the power system specification. The power system specification specifies in detail the communication protocols, data transmission methods and other standards between different devices in the power system.

[0003] As the bottom-level communication module in the power system, the front-end module is a module that summarizes the basic power data. The front-end module is mainly used to communicate with other devices to collect, process and transmit data. The communication between the front-end module and other devices is also achieved through messages. Users can view the messages to clarify the interaction between the front-end module and other devices or the operating status of the monitoring system.

[0004] However, the inventors have found that the front-end module in the prior art usually has a storage function for protocol messages. That is, the message storage module is usually coupled to the front-end module. In this way, when the front-end module interacts with other devices through messages, the front-end module will directly write the interacted messages into a local file for storage.

[0005] The prior art method of coupling the message storage module to the front module causes the user to download the message before viewing it, and it is difficult to view the real-time message in time, which is difficult to meet the user's needs. Summary of the invention

[0006] The present application aims to provide a message transmission method, system, device, storage medium and computer program product to improve user convenience.

[0007] According to one aspect of the present application, a message transmission method performed by a message distribution module is proposed. The message transmission method is applied to a message transmission system. The message transmission system includes a front-end module, a message distribution module, and a message output module. The front-end module interacts with a substation terminal device via messages. The message distribution module receives message subscriptions. The message output module subscribes to messages from the message distribution module in response to a user's instruction. The message transmission method includes a message distribution module receiving a real-time message sent by the front-end module and a message identifier corresponding to the real-time message. The real-time message is a message generated by the interaction between the front-end module and the substation terminal device. According to the message identifier, the real-time message is sent to the first target message output module that has subscribed to the real-time message to output the real-time message.

[0008] According to another aspect of the present application, a message transmission method performed by a front-end module is proposed. The front-end module is a module of a message transmission system. The message transmission system includes a front-end module, a message distribution module, and a message output module. The front-end module interacts with a substation terminal device via messages. The message distribution module receives message subscriptions. The message output module, in response to a user's instruction, subscribes to messages from the message distribution module. The message transmission method includes the front-end module collecting real-time messages while interacting with the substation terminal device via messages. Determine the message identifier of the real-time message. Send the real-time message and the message identifier to the message distribution module so that the message distribution module executes the message transmission method described in the above aspect.

[0009] According to another aspect of the present application, a message transmission system is proposed. The message transmission system includes a front-end module, a message distribution module, and a message output module. The front-end module interacts with the substation terminal device through messages, and determines the message identifier based on the interacted real-time message. The message distribution module receives the real-time message and the message identifier from the front-end module, and receives the message subscription. The message output module subscribes to the message distribution module for the message in response to the user's instruction. The message distribution module also sends the real-time message to the first target message output module according to the message identifier corresponding to the real-time message, so as to publish the real-time message. Among them, the first target message output module is a message output module that has subscribed to the real-time message.

[0010] According to another aspect of the present application, an electronic device is proposed, which includes: one or more processors; a storage device for storing one or more programs; when the one or more programs are executed by the one or more processors, the one or more processors implement the method as described above.

[0011] According to another aspect of the present application, a non-volatile computer-readable medium is provided, on which a computer program is stored. When the program is executed by a processor, the method described above is implemented.

[0012] According to another aspect of the present application, a computer program product is provided, which includes a computer program stored on a computer-readable storage medium, wherein the computer program includes program instructions, and when the program instructions are executed by a computer, the method described above is implemented.

[0013] Beneficial Effects The present application utilizes a message distribution module to decouple the front-end module from the message output module, so that the message that the front-end module interacts with the substation terminal device is not directly stored locally, but the message distribution module distributes the message to the message output module that subscribes to the message, so that the message output module outputs the message. In this way, users do not have to download the message from the front-end module to view it, but can automatically distribute the message by the message distribution module, so that they can directly view the message, which improves user convenience.

[0021] The following is a clear and complete description of the technical solution of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0022] According to one aspect of the present application, an embodiment of the present application provides a message transmission method, which is applied to a message transmission system.

[0023] Figure 1 The system architecture of the message transmission system is shown. Figure 1 The message transmission system includes a front-end module 01, a message distribution module 02 and a message output module 03. The front-end module 01 is used to interact with the substation terminal device. The message output module 03 is used to respond to user instructions to subscribe to messages from the message distribution module 02. The message distribution module 02 is used to receive the subscription of the message output module 03 to the message and execute the message transmission method.

[0024] Figure 2 The flow of the message transmission method is shown. Figure 2 , the message transmission method includes steps S210-S220.

[0025] In step S210, the message distribution module 02 receives the real-time message sent by the front-end module 01 and the message identifier corresponding to the real-time message.

[0026] According to the exemplary embodiment, the real-time message is a message generated by the interaction between the front-end module 01 and the substation terminal device. The message identifier is a message identifier determined by the front-end module 01 according to the message, and is used to indicate the message type of the message.

[0027] The message type may be specifically a type classified according to a message interaction channel. For example, messages for the same message interaction channel are of one message type. The message identifier may be an identifier describing a substation terminal device communicating with the front-end module 01 to indicate the message interaction channel of the message.

[0028] Exemplarily, when the front-end module 01 sends a message to the substation terminal device, or when the front-end module 01 receives a message sent by the substation terminal device, the front-end module 01 will determine the message identifier of the real-time message according to the interactive real-time message. And the front-end module 01 will also send the real-time message and the message identifier to the message distribution module 02, so that the message distribution module 02 receives the real-time message and the message identifier.

[0029] In step S220, the message distribution module 02 sends the real-time message to the first target message output module that has subscribed to the real-time message according to the message identifier, so as to output the real-time message.

[0030] According to the exemplary embodiment, the user can subscribe to messages according to the needs, and the message output module 03 is user-oriented. The user can send a message subscription instruction for the target message type to the message output module 03, and the message output module 03 subscribes to the message distribution module 02 for the message of the target message type according to the message subscription instruction.

[0031] According to the example embodiment, in step S220, when the message distribution module 02 receives the real-time message and the message identifier, it determines the message type of the real-time message according to the message identifier, and sends the real-time message to the message output module 03 that has subscribed to the real-time message. In this way, the message output module 03 can receive the real-time message and output the real-time message for the user to view.

[0032] For example, when a user wants to view the messages exchanged between the substation terminal device a1 and the front-end module 01 , the user can send a message subscription instruction for the substation terminal device a1 to the message output module 03 . The message output module 03 then subscribes the substation terminal device a1 to the message distribution module 02 .

[0033] When the message distribution module 02 receives the real-time message and the message identifier, the message distribution module 02 will send the message exchanged between the substation terminal device a1 and the front-end module 01 to the message output module 03 according to the message identifier. The message output module 03 can receive the subscribed related message and can directly display the message or store the message so that the user can view it in time.

[0034] In the embodiment of the present application, the message distribution module 02 is used to decouple the front module 01 from the message output module 03, so that the message interacted by the front module 01 is not directly stored locally, but the message distribution module 02 distributes the message to the message output module 03 that subscribes to the message, so that the message output module 03 outputs the message. In this way, the user does not have to download the message from the front module 01 to view it, but the message distribution module 02 can automatically distribute the message to view the message directly, which improves user convenience.

[0035] Moreover, in the prior art, the front module 01 and the message storage module are coupled, so that the front module 01 writes the message into a local file and only supports downloading the message for viewing. This approach also has other disadvantages. First, the front module 01 stores all the messages into a local file, which will occupy a large amount of hard disk space. Secondly, since the space occupied by the message will become larger and larger as the system runs in this approach, it is necessary to additionally manage the locally stored messages, such as deleting or compressing them.

[0036] In the present application, the message of the front module 01 is not directly stored in the local file, but is directly distributed to the subscribed message output module 03 by the message distribution module 02. In this way, the hard disk space occupied by the message of the front module 01 can be reduced, and even no hard disk space can be occupied. In addition, since the message is not directly stored in the hard disk space, there is no need to manage the messages stored in the hard disk space.

[0037] According to some embodiments, the message distribution module 02 of the present application may specifically be RabbitMQ message middleware.

[0038] RabbitMQ is an open source message broker software that implements the Advanced Message Queuing Protocol for asynchronous communication between different applications.

[0039] RabbitMQ message middleware can support cross-node access in the network and supports secondary development in almost all commonly used programming languages. In this way, users can choose easy-to-use programming languages ​​and nodes according to the needs of actual scenarios for secondary development, which improves the applicability of the message distribution module 02 of this application.

[0040] In addition, RabbitMQ can support message queue localization and can distribute messages through message queues to improve message reliability.

[0041] According to some embodiments, reference Figure 3 , the message transmission method may further include step S230.

[0042] In step S230 , the message distribution module 02 discards the real-time message if the real-time message is not subscribed by the message output module 03 .

[0043] According to an example embodiment, when the real-time message is not subscribed by the message output module 03, the message distribution module 02 may directly discard the message, thereby reducing the occupation of memory resources by messages that are not of interest.

[0044] According to some embodiments, the front-end module 01, the message distribution module 02 and the message output module 03 may be deployed on the same server or on different servers, which is not limited here.

[0045] For example, the front-end module 01, the message distribution module 02 and the message output module 03 are deployed on the same server, or the front-end module 01, the message distribution module 02 and the message output module 03 are deployed on their respective corresponding servers.

[0046] It is worth mentioning that when each module is deployed on different servers, it is necessary to ensure that the servers with data interaction can communicate with each other, that is, the two servers with data interaction need to have the same network environment.

[0047] For example, the front-end module 01 needs to send a message to the message distribution module 02 , so the server of the front-end module 01 and the server of the message distribution module 02 are required to be able to communicate with each other.

[0048] For example, the message distribution module 02 will send the subscribed message to the message output module 03, and the message output module 03 will also subscribe to the message from the message distribution module 02. Therefore, it is required that the message distribution module 02 and the message output module 03 can also communicate with each other, that is, the message distribution module 02 and the message output module 03 are in the same network environment. In this way, the user can subscribe to the message from the message distribution module 02 through the message output module 03 in the application of the terminal.

[0049] According to some embodiments, reference Figure 4 The message transmission method also includes step S410, step S420 and step S430.

[0050] In step S410, the message distribution module 02 determines the data distribution mode according to the number of message output modules 03 in the message transmission system.

[0051] According to an example embodiment, the data distribution mode includes a broadcast publishing mode and a subscription publishing mode. In the broadcast publishing mode, the message distribution module 02 can use multiple switches of the fanout type to broadcast data to all subscribers, which is suitable for application scenarios with multiple consumers.

[0052] In the subscription and publishing mode, the message distribution module 02 can use a switch of type direct and distribute data through different routers, which is suitable for application scenarios with only one consumer.

[0053] Exemplarily, in step S410, when the number of message output modules 03 in the message transmission system is 1, the message distribution module 02 determines that the data distribution mode is the subscription publishing mode. When the number of message output modules 03 in the message transmission system is at least two, the message distribution module 02 determines that the data distribution mode is the broadcast publishing mode.

[0054] In step S420, when the data distribution mode is the subscription publishing mode and the message distribution module 02 receives a subscription instruction for the target message interaction channel sent by the message output module 03, it determines the target subscription message queue.

[0055] According to an example embodiment, the target subscription message queue is a subscription message queue corresponding to the target message interaction channel.

[0056] The subscription message queue is a message queue created in advance according to each message interaction channel, and there is a one-to-one correspondence between the subscription message queue and the message interaction channel.

[0057] Exemplarily, in the message transmission system, the front-end module 01 performs message interaction with the substation terminal devices b1 - b3 .

[0058] The message interaction channels of the message transmission system are respectively the message interaction channel c1 between the front module 01 and the substation terminal device b1, the message interaction channel c2 between the front module 01 and the substation terminal device b2, and the message interaction channel c3 between the front module 01 and the substation terminal device b3.

[0059] Each message interaction channel corresponds to a subscription message queue. For example, message interaction channel c1 corresponds to subscription message queue d1, message interaction channel c2 corresponds to subscription message queue d2, and message interaction channel c3 corresponds to subscription message queue d3.

[0060] In the subscription publishing mode, the message generated by the message interaction channel will be distributed to the corresponding subscription message queue by the message distribution module 02 using switches and routers. The subscription message queue will distribute the message to the message output module 03 of the subscription message.

[0061] In the subscription publishing mode, the message distribution module 02 distributes the message to the corresponding subscription message queue through the switch and the router. In addition, the message distribution module 02 is provided with a direct type switch and a preset number of routers.

[0062] There is a one-to-one correspondence between routers and message exchange channels. For example, message exchange channel b1 corresponds to router e1, and message exchange channel b2 corresponds to router e2.

[0063] In the subscription publishing mode, all messages of the message interaction channels b1-b3 will be sent to the direct type switch. The switch will then distribute the message to the router corresponding to the message interaction channel, and then the router will distribute the message to the subscription message queue corresponding to the message interaction channel. Then the subscription message queue will send the message to the message output module 03.

[0064] According to an example embodiment, in the above step S420, in the subscription publishing mode, when the message distribution module 02 receives a subscription instruction for a target message interaction channel, the subscription message queue corresponding to the target message interaction channel can be used as the target subscription message queue.

[0065] According to the example embodiment, the target subscription message queue is used to distribute messages of the target message interaction channel. In the process of distributing messages by the subscription message queue, the message is usually sent to the message output module 03 bound to the subscription message queue. That is, the subscription message queue is used to distribute the messages in the queue to the bound message output module 03.

[0066] In step S430, the message distribution module 02 binds the second target message output module to the target subscription message queue, so that the target subscription message queue sends the message of the target message interaction channel to the second target message output module.

[0067] According to the example embodiment, the second target message output module is a message output module 03 that sends a subscription instruction for a target message interaction channel.

[0068] For example, when any message output module x1 sends a subscription instruction for the message interaction channel b1, the message distribution module 02 binds the subscription message queue c1 to the any message output module x1 so that the subscription message queue c1 can send messages of the message interaction channel b1 to the any message output module x1.

[0069] According to some embodiments, reference Figure 5 , the message transmission method also includes steps S510-S530.

[0070] In step S510, when the data distribution mode is the broadcast publishing mode and a subscription instruction for a target message interaction channel is received from the message output module 03, the message distribution module 02 determines a target broadcast switch corresponding to the target message interaction channel.

[0071] According to an exemplary embodiment, the broadcast switch is pre-set according to the message interaction channel, and the message interaction channel and the broadcast switch are in a one-to-one correspondence.

[0072] For example, the message interaction channel b1 corresponds to the broadcast switch f1, the message interaction channel b2 corresponds to the broadcast switch f2, and the message interaction channel b3 corresponds to the broadcast switch f3.

[0073] Messages for message interaction channel b1 will be distributed via broadcast switch f1, and so on. Messages for message interaction channel b2 will be distributed via broadcast switch f2, and messages for message interaction channel b3 will be distributed via broadcast switch f3.

[0074] According to the example embodiment, in step S510, when the data distribution mode is the broadcast publishing mode, if the message distribution module 02 receives a subscription instruction for the target message interaction channel sent by the message output module 03, the broadcast switch corresponding to the target message interaction channel can be determined as the target broadcast switch. In this way, the target broadcast switch distributes the message of the target message interaction channel.

[0075] In step S520 , the message distribution module 02 determines the target broadcast message queue corresponding to the third target message output module 03 .

[0076] According to the exemplary embodiment, in the message distribution module 02, a broadcast message queue is respectively provided for each message output module 03 in the message transmission system, that is, there is a one-to-one correspondence between the message output module 03 and the broadcast message queue.

[0077] The broadcast message queue is used to send the messages in the queue to the corresponding message output module 03.

[0078] For example, the message transmission system has a first message output module g1 and a second message output module g2, and a broadcast message queue h1 and a broadcast message queue h2 are set in the message distribution module 02. The broadcast message queue h1 is used to send messages in the queue to the first message output module g1, and the broadcast message queue h2 is used to send messages in the queue to the second message output module g2.

[0079] According to the example embodiment, in step S520, the third target message output module is a message output module 03 that generates a subscription instruction for the target message interaction channel in the broadcast publishing mode. For example, the first message output module g1 sends a subscription instruction for the message interaction channel b1. In step S520, the broadcast message queue corresponding to the first message output module g1 is the broadcast message queue h1.

[0080] In step S530 , the message distribution module 02 binds the target broadcast switch with the target broadcast message queue so that the target broadcast switch sends the message of the target message interaction channel to the target broadcast message queue, and the target broadcast message queue sends the message to the third target message output module 03 .

[0081] For example, it is assumed that the first message output module g1 sends a subscription instruction to the message interaction channel b1, the target broadcast switch is the broadcast switch f1, and the target broadcast message queue is the broadcast message queue h1. In step S530, the message distribution module 02 binds the broadcast switch f1 to the broadcast message queue h1. In this way, when the message interaction channel b1 generates a message, after the message is output by the front module 01 to the message distribution module 02, the message distribution module 02 will distribute the message to the bound broadcast message queue h1 through the broadcast switch f1. The broadcast message queue h1 can send the message to the first message output module g1.

[0082] According to some embodiments, when there is a message output module 03 that subscribes to a message from a message distribution module 02, the message distribution module 02 can establish a binding relationship between the switch, the message queue and the message output module 03 through the above-mentioned steps S410-step S430 and steps S510-step S530, so that when the subsequent message distribution module 02 receives a message, it can be accurately transmitted to the message output module 03 that subscribes to the message.

[0083] According to some embodiments, reference Figure 6 In the above step S220, the message distribution module 02 sends the real-time message to the first target message output module that has subscribed to the real-time message according to the message identifier, which may specifically include step S221 and step S222.

[0084] In step S221, when the data distribution mode is the subscription publishing mode, the message distribution module 02 determines the subscription message queue corresponding to the real-time message according to the message identifier and the first preset mapping relationship.

[0085] According to the exemplary embodiment, the message identifier is an identifier of a message interaction channel characterizing the message, and is generated by the front-end module 01 according to the message.

[0086] Exemplarily, the message identifier may be determined by the front-end module 01 according to a preset subscription switch name and a router name. The router name may be determined by the front-end module 01 according to the number of the message interaction channel of the message.

[0087] For example, the real-time message is a message generated by the message interaction channel b1. The preset subscription switch name is fepmessage. The message interaction channel b1 corresponds to the router e1. The name of the router e1 can be route&channel&1. The front module 01 determines that the message identifier of the real-time message can be fepmessage, route&channel&1.

[0088] According to an example embodiment, the first preset mapping relationship includes a mapping relationship between a message interaction channel and a subscription message queue. Each message interaction channel corresponds to a subscription message queue, and the subscription message queue is used to receive and distribute messages of the corresponding message interaction channel.

[0089] According to an example embodiment, in step S221, when the data distribution mode is a subscription publishing mode, the message distribution module 02 can determine the message interaction channel of the real-time message based on the message identifier, and then determine the subscription message queue corresponding to the real-time message based on the message interaction channel and the first preset mapping relationship.

[0090] Exemplarily, when the real-time message is a message generated by the message interaction channel b1, in the subscription and publication mode, the message distribution module 02 determines that the subscription message queue is the subscription message queue c1.

[0091] In step S222, the message distribution module 02 sends the real-time message to the subscription message queue corresponding to the real-time message through the preset subscription switch, so that the subscription message queue corresponding to the real-time message sends the real-time message to the first target message output module.

[0092] According to the example embodiment, the preset subscription switch is the only switch used in the subscription publishing mode. For example, the above-mentioned direct type switch, and the switch name is fepmessage. That is, for any message interaction channel, the message will be distributed through the preset subscription switch in the subscription publishing mode.

[0093] Exemplarily, for a real-time message from the message interaction channel b1, in the subscription and publishing mode, the message distribution module 02 sends the real-time message to the subscription message queue c1 through the direct type switch and the router named route&channel&1.

[0094] When the first target message output module has subscribed to the message of the message interaction channel b1, the first target message output module has been bound to the subscription message queue c1. Therefore, the subscription message queue c1 will send the received real-time message to the first target message output module.

[0095] According to some embodiments, reference Figure 7 In the above step S220, the message distribution module 02 sends the real-time message to the first target message output module that has subscribed to the real-time message according to the message identifier, which can also be achieved through steps S710 and S720.

[0096] In step S710, when the data distribution mode is the broadcast publishing mode, the message distribution module 02 determines the target broadcast switch according to the message identifier and the second preset mapping relationship.

[0097] According to the example embodiment, in the broadcast publishing mode, the message distribution module 02 sends the real-time message to the first target message output module according to the message identifier through the steps S710 and S720.

[0098] According to an exemplary embodiment, the message identifier may also include the name of the broadcast switch. The name of the broadcast switch may be specifically set by the front-end module 01 according to the number of the message interaction channel corresponding to the broadcast switch.

[0099] Each message interaction channel corresponds to a broadcast switch, and the broadcast switch is used to distribute the messages of the corresponding message interaction channel in the broadcast publishing mode.

[0100] For example, the real-time message is a message generated by the message interaction channel b1. The message interaction channel b1 is numbered 1, and the corresponding broadcast switch is the broadcast switch e1.

[0101] The name of the broadcast switch is named according to a preset naming rule, for example, the name of the broadcast switch is fep&channel&id. ID is the number of the message interaction channel corresponding to the broadcast switch. ID is the unique identifier of each message interaction channel.

[0102] For example, the name of the broadcast switch e1 is fep&channel&1. The front-end module 01 determines that the message identifier of the real-time message may be fep&channel&1.

[0103] According to some embodiments, the broadcast switch can be created manually by a staff member according to actual conditions, and the name of the broadcast switch can be manually set. The staff member can also define the attribute of the broadcast switch as persistent.

[0104] Persistent broadcast switches can still exist after RabbitMQ is restarted, which can ensure the reliability of message delivery.

[0105] According to an example embodiment, the second preset mapping relationship includes a mapping relationship between a broadcast switch and a message interaction channel. In step S710, the message distribution module 02 can determine the message interaction channel corresponding to the message according to the message identifier, and then determine the broadcast switch according to the second preset mapping relationship. For example, the real-time message in the above example corresponds to the broadcast switch e1.

[0106] Alternatively, in step S710, the message distribution module 02 may directly determine the name of the broadcast switch according to the message identifier of the real-time message, so as to determine the target broadcast switch.

[0107] In step S720, the message distribution module 02 distributes the real-time message to the target broadcast message queue through the target broadcast switch, so that the target broadcast message queue sends the real-time message to the first target message output module.

[0108] Among them, the target broadcast message queue is the broadcast message queue corresponding to the first target message output module.

[0109] According to the exemplary embodiment, in the broadcast publishing mode, each message output module 03 corresponds to a broadcast message queue. Each message interaction channel corresponds to a broadcast switch.

[0110] For the message output module 03 that subscribes to the message interaction channel, the broadcast message queue of the message output module 03 has a binding relationship established with the broadcast switch in advance.

[0111] In this way, when the broadcast switch receives the relevant message, the broadcast switch can output the message to the bound broadcast message queue. The broadcast message queue then transmits the message in the queue to the corresponding message output module 03.

[0112] Exemplarily, assuming that both the third message output module g3 and the fourth message output module g4 subscribe to the real-time message of the message interaction channel b1, the broadcast switch f1 is bound to the broadcast message queue h3 and the broadcast message queue h4 respectively.

[0113] In step S720, when the message distribution module 02 receives the real-time message, the real-time message is distributed to the broadcast message queue h3 and the broadcast message queue h4 through the broadcast switch f1. The broadcast message queue h3 then sends the real-time message to the third message output module g3, and the broadcast message queue h3 distributes the real-time message to the fourth message output module g4.

[0114] According to some embodiments, the message distribution module 02 uses RabbitMQ message middleware to implement message distribution. Since the message queue in RabbitMQ supports the setting of multiple attributes, the user can flexibly adjust the data receiving scheme by setting the attributes of the message queue.

[0115] According to some embodiments, in order to improve data reliability and ensure system security, the user may also perform the following settings on the message queue of the RabbitMQ message middleware.

[0116] In some embodiments, users can set each message queue (broadcast message queue and subscription message queue) to be persistent, so that even if the RabbitMQ server is restarted, the persistent message queue will not be deleted.

[0117] In some embodiments, the user can also set the maximum length of the message queue (x-max-length). In this way, the server will not crash due to too many messages piling up in the message queue. It is worth noting that the setting value of the maximum length of the message queue should be set in consideration of the user's consumption capacity and the operating system configuration.

[0118] In some embodiments, the user can also set an expiration date (x-message-ttl parameter, in milliseconds) for all messages in the message queue. In this way, all messages in the message queue will have the same expiration date. If the survival time of the message in the message queue exceeds the expiration date and has not been consumed, the message will be deleted from the message queue.

[0119] It should be clearly understood that the present application describes how to form and use specific examples, but the present application is not limited to any details of these examples. On the contrary, based on the teaching of the content disclosed in the present application, these principles can be applied to many other embodiments.

[0120] Those skilled in the art may understand that all or part of the steps to implement the above embodiments are implemented as a computer program executed by a CPU. When the computer program is executed by the CPU, the above functions defined by the above method provided in this application are performed.

[0121] According to another aspect of the present application, an embodiment of the present application provides another message transmission method, which is also applied to a message transmission system.

[0122] Reference Figure 1 The message transmission system includes a front-end module 01, a message distribution module 02 and a message output module 03. The front-end module 01 interacts with the substation terminal device. The message distribution module 02 receives the message subscription. The message output module 03 subscribes to the message distribution module 02 in response to the user's instruction.

[0123] The message transmission method is executed by the front-end module 01. Figure 8 The message transmission method includes steps S810 to S830.

[0124] In step S810, the front-end module 01 collects real-time messages when interacting with the substation terminal device.

[0125] In step S820, the front-end module 01 determines the message identifier of the real-time message.

[0126] In step S830, the front-end module 01 sends the real-time message and the message identifier to the message distribution module 02, so that the message distribution module 02 executes the message transmission method described in the above steps S210 to S220.

[0127] Exemplarily, when the front-end module 01 sends a message to the substation terminal device, or when the front-end module 01 receives a message sent by the substation terminal device, the front-end module 01 collects a real-time message. In step S820, the front-end module 01 determines the message identifier of the real-time message, and in step S830, the front-end module 01 sends the real-time message and the message identifier to the message distribution module 02.

[0128] When receiving the real-time message and the message identifier, the message distribution module 02 distributes the real-time message to the first target message output module that subscribes to the real-time message. The first target message output module directly faces the user and can directly display the real-time message according to the user's needs or store the real-time message according to the user's needs.

[0129] The present application decouples the front module 01 from the message output module 03 through the message distribution module 02. In this way, the user can directly subscribe to the message of interest, and the message can be automatically transmitted to the user after it is generated, so that the user can obtain the message without having to download it from the front module 01 to view the message, which improves the convenience of the user.

[0130] According to some embodiments, in the above step S820, the front-end module 01 determines the message identifier of the real-time message, and specifically determines the message identifier of the real-time message according to the message interaction channel of the real-time message.

[0131] According to an example embodiment, the message identifier may specifically include a subscription message identifier and a broadcast message identifier.

[0132] The subscription message identifier is used by the message distribution module 02 to determine the router to determine the subscription message queue in the subscription publishing mode.

[0133] According to an example embodiment, the subscription message identifier includes a preset subscription switch name and a subscription router name.

[0134] A preset subscription switch and a preset number of subscription routers are pre-set in the message distribution module 02. Each subscription router corresponds to a message interaction channel. The user pre-sets the name of the preset subscription switch and the names of each subscription router, for example, the preset subscription switch name is set to fepmessage, and each subscription router is named according to the router naming rule.

[0135] Exemplarily, the name of the subscription router may be route&channel&id, where id is the number of the message interaction channel and id is a unique identifier of each message interaction channel.

[0136] Exemplarily, in step S820, when the front-end module 01 receives the real-time message, it can determine the name of the preset subscription switch and the name of the subscription router corresponding to the message interaction channel according to the message interaction channel of the real-time message.

[0137] For example, for a message of the message interaction channel b1, the number of the message interaction channel is 1, and the subscription message identifier of the message is: fepmessage, route&channel&1.

[0138] According to an example embodiment, the broadcast message identifier is used by the message distribution module 02 to determine the broadcast switch in the broadcast publishing mode.

[0139] A preset number of broadcast switches are pre-set in the message distribution module 02. Each broadcast switch corresponds to a message interaction channel. The user pre-names each broadcast switch according to the naming rules of the broadcast switch.

[0140] For example, the name of the broadcast switch can be named in the form of "fep&channel&id". ID is the number of the message interaction channel corresponding to the broadcast switch. ID is the unique identifier of each message interaction channel.

[0141] In step S820, when the front-end module 01 receives the real-time message, it can determine the name of the broadcast switch according to the message interaction channel of the real-time message, and further determine the broadcast message identifier of the real-time message.

[0142] For example, for a message on the message interaction channel b1, the number of the message interaction channel is 1, and the broadcast message identifier of the message is: fep&channel&1.

[0143] According to some embodiments, in the above step S830, the front-end module 01 sends the real-time message and the message identifier to the message distribution module 02. Specifically, the message transmission direction of the real-time message can be determined first. Then, the front-end module 01 adds the transmission direction identifier to the real-time message according to the message transmission direction. Then, the front-end module 01 sends the real-time message and the message identifier with the added transmission direction identifier to the message distribution module 02.

[0144] According to the example embodiment, the message exchange is usually carried out in frames, and a complete message frame includes a frame header, a control field, an address field, a data field, a frame tail, etc. When the front module 01 transmits the message to the message distribution module 02, a transmission time stamp and a transmission direction identifier can be added to the message.

[0145] There are two types of transmission directions, namely, front module 01→substation terminal device, and substation terminal device→front module 01. When the front module 01 adds a transmission direction identifier to the message, the front module 01 can be used as the reference direction, and a sending identifier can be added to the message sent by the front module 01, and a receiving identifier can be added to the message received by the front module 01.

[0146] The transmitted time stamp can be accurate to millisecond level to record the moment when the front-end module 01 receives a message or sends a message.

[0147] According to some embodiments, a message parsing module may be built into the front-end module 01. The message parsing module may parse the message and send the parsed message together with the original message to the message distribution module 02 for the convenience of subscribers to view.

[0148] Exemplarily, the front-end module 01 records the message after the transmission identifier, and the message after parsing is: 2024-09-1012:12:22.456789 [send] 68 04 07 00 00 00 [explain] start frame.

[0149] According to another aspect of the present application, a message transmission system is provided. Figure 1 The message transmission system includes a front-end module 01, a message distribution module 02 and a message output module 03.

[0150] The front-end module 01 interacts with the substation terminal device through messages, and determines the message identifier according to the interacted real-time message. The message output module 03 responds to the user's instruction to subscribe to the message distribution module 02. The message distribution module 02 receives the real-time message and message identifier from the front-end module 01, and receives the message subscription. The message distribution module 02 also sends the real-time message to the first target message output module according to the message identifier corresponding to the real-time message, so as to publish the real-time message. Among them, the first target message output module is the message output module 03 that has subscribed to the real-time message.

[0151] According to the example embodiment, when the front-end module 01 sends a message to the substation terminal device, or when the front-end module 01 receives a message sent by the substation terminal device, the front-end module 01 collects a real-time message. The front-end module 01 determines the message identifier of the real-time message, and the front-end module 01 then sends the real-time message and the message identifier to the message distribution module 02.

[0152] When receiving the real-time message and the message identifier, the message distribution module 02 distributes the real-time message to the first target message output module that subscribes to the real-time message. The first target message output module directly faces the user and can directly display the real-time message according to the user's needs or store the real-time message according to the user's needs.

[0153] The present application decouples the front module 01 from the message output module 03 through the message distribution module 02. In this way, the user can directly subscribe to the message of interest, and the message can be automatically transmitted to the user after it is generated, so that the user can obtain the message without having to download it from the front module 01 to view the message, which improves the convenience of the user.
