Description

Technical Field

[0001] This invention belongs to the field of control technology, specifically relating to a method, apparatus, medium, device, and program product for determining a communication master node. Background Technology

[0002] Multicast technology refers to a network communication method where a single sender corresponds to multiple receivers. By transmitting a single information stream to multiple receivers, network communication traffic can be reduced when multiple receivers are simultaneously listening to or viewing the same resource.

[0003] Existing multicast technology consists of a control terminal, a communication terminal, and an execution terminal forming a local area network. The control terminal sends its own node information and control information to the multicast domain, while also receiving information from other nodes; the communication terminal transmits and distributes data according to the multicast data packet address information; and the execution terminal executes control commands based on the multicast data.

[0004] When multiple workstations on a local area network are running the same control software, i.e., when there are multiple control terminals, the control commands issued by the multiple control terminals may conflict (such as being issued simultaneously or another node triggering a new command before the previous command is executed, which will cause execution disorder at the execution terminal). Summary of the Invention

[0005] To address the aforementioned technical problems, this invention proposes a method, apparatus, medium, device, and program product for determining a communication master node. This application obtains the target node's current self-node information and preset conditions; obtains current other-node information sent by other nodes from the communication terminal; determines whether the target node meets the preset conditions based on the current self-node information and the current other-node information; and determines the target node as the communication master node when the target node meets the preset conditions. Each node determines its master-slave state through distributed computing, innovatively proposing a closed-loop control management technology. This avoids the potential for account permission theft and the additional overhead of account information maintenance associated with traditional methods, ensuring that only one software node is allowed to issue execution commands during the usage process.

[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention includes five aspects.

[0007] In a first aspect, this application provides a method for determining a communication master node, comprising: obtaining the target node's own current self-node information and preset conditions; obtaining the current other-node information sent by other nodes from the communication terminal; determining whether the target node meets the preset conditions based on the current self-node information and the current other-node information; and determining the target node as a communication master node when the target node meets the preset conditions.

[0008] In some embodiments, the current self-node information includes: the current self-node startup duration; the current other-node information includes: the current node status of other nodes; determining whether the target node meets the preset condition based on the current self-node information and the current other-node information includes: determining the number of communication master nodes whose current node status is a communication master node based on the current node status of each other node; determining whether the target node meets the preset condition based on the number of communication master nodes and the self-node startup duration; wherein, when the self-node startup duration is greater than or equal to the preset duration and the number of communication master nodes is 0, it is determined that the target node meets the preset condition.

[0009] In some embodiments, the current self-node information includes: self-node ID information; the current other-node information includes: control transfer information; determining whether the target node meets the preset conditions based on the current self-node information and the current other-node information further includes: determining target ID information based on the control transfer information; determining whether the target node meets the preset conditions based on the target ID information and the self-node ID information; wherein, when the target ID information is the same as the self-node ID information, it is determined that the target node meets the preset conditions.

[0010] In some embodiments, the method further includes: when the number of other nodes is 1, obtaining the self-node status of the target node; when the self-node status is a communication master node, issuing a communication master node conflict warning.

[0011] In some embodiments, the method further includes: when the self-node is in the state of a communication slave node, determining that the target node is a communication slave node; and locking the control interface of the target node.

[0012] In some embodiments, the method further includes: when the target ID information and the self-node ID information are different, obtaining the self-node status of the target node; when the self-node status is a communication master node, issuing a communication master node conflict warning.

[0013] Secondly, this application proposes a device for determining a communication master node, comprising: a first acquisition module for acquiring the current self-node information of the target node and preset conditions; a second acquisition module for acquiring the current other-node information sent by other nodes from the communication terminal; a first judgment module for determining whether the target node meets the preset conditions based on the current self-node information and the current other-node information; and a first determination module for determining the target node as a communication master node when the target node meets the preset conditions.

[0014] Thirdly, this application proposes a computer electronic production apparatus, including a memory, a processor, and a computer program stored in the memory, wherein the processor executes the computer program to implement the steps of any of the methods described in the first aspect.

[0015] Fourthly, this application proposes a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the method described in any of the first aspects.

[0016] Fifthly, this application proposes a computer program product comprising a computer program that, when executed by a processor, implements the steps of the method described in any of the first aspects.

[0017] The beneficial effects of this invention are as follows: This application obtains the target node's current self-node information and preset conditions; obtains the current other-node information sent by other nodes from the communication terminal; determines whether the target node meets the preset conditions based on the current self-node information and the current other-node information; and determines the target node as the communication master node when the target node meets the preset conditions. Each node determines its master-slave state through distributed computing, innovatively proposing a closed-loop control management technology. This avoids the potential for account permission theft and the additional overhead of account information maintenance in traditional methods, ensuring that only one software node is allowed to issue execution commands during the usage process.

It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0026] Example 1:

[0027] In the existing technology, when multiple workstations in a local area network are running the same standalone software (CS software mode), the control commands issued by multiple node software may conflict (such as being issued at the same time or another node triggering a new command before the previous command is executed), which will lead to execution disorder.

[0028] To address the problems existing in the current technology, such as Figure 1 As shown, this application provides a method for determining a communication master node. This method is applied to electronic production equipment, which can be a server, mobile terminal, computer, cloud platform, etc. The data processing functionality provided in this application embodiment can be implemented by the processor of the electronic production equipment calling program code, wherein the program code can be stored in a computer storage medium. The method for determining the communication master node includes:

[0029] Step S1: Obtain the target node's current self-node information and preset conditions.

[0030] Step S2: Obtain the current other node information sent by other nodes from the communication end.

[0031] A local area network (LAN) includes an execution device, a communication terminal, and multiple nodes. The master node can control the execution device through the communication terminal, and each node has the potential to become the master node. These nodes continuously send node information to the communication terminal. Therefore, from the perspective of a single node, the node information sent by that node is called self-node information, while the node information sent by other nodes is called other-node information. Each node also receives other-node information from other nodes, using this information and its own node information to determine whether it can become the master node. The information exchange between multiple nodes forms a multicast domain. The node information sent by each node includes: node ID information, node status information, control transfer information, node startup duration, and control commands. The node status information includes two states: master node and slave node. Only the master node can issue control commands. However, the above information alone is insufficient to determine the node status of each node. Therefore, this application also presets conditions, allowing each node to compete for master status based on these conditions.

[0032] In this application, any node is used as the target node. For a target node to determine whether it can become the communication master node, it needs to obtain the current other node information of other nodes and its own current self node information. The current other node information needs to be obtained from the communication end, i.e., the multicast domain.

[0033] Step S3: Determine whether the target node meets the preset conditions based on the current self node information and the current other node information.

[0034] In some embodiments, step S3, "determining whether the target node meets the preset conditions based on the current self-node information and the current other-node information," includes:

[0035] Step S31: Determine the number of communication master nodes whose current node status is a communication master node based on the current node status of each other node.

[0036] Step S32: Determine whether the target node meets the preset conditions based on the number of communication master nodes and the startup time of the slave nodes.

[0037] Since only one node can control an execution device in this application, it is necessary to count the number of nodes in the other nodes whose status is that of a communication master node. Because short node startup times may lead to unstable connections or other issues, this application considers the node startup time during the master-competition process. Competition will only occur when both the startup time and the master-competition conditions are met. Therefore, in this application, the target node is determined as the communication master node when the number of communication master nodes in the other nodes is 0 and the startup time of the self-node is greater than or equal to 10 seconds. The self-node startup time refers to the time elapsed after the self-node has finished starting.

[0038] In some embodiments, besides multiple nodes competing for master status, a node can also be designated as the communication master node by other nodes. Therefore, step S3, "determining whether the target node meets the preset conditions based on the current self-node information and the current other-node information," further includes:

[0039] Step S33: Determine the target ID information based on the control transfer information.

[0040] Step S34: Determine whether the target node meets the preset conditions based on the target ID information and the self-node ID information.

[0041] Although node information normally includes control transfer information, this information is invalid when no control transfer occurs. It becomes valid only when a control transfer is required, and includes the target ID information designated as the communication master node. If the target ID matches the self-ID of the self-node, then the self-node is determined to be the communication master node.

[0042] Step S4: When the target node meets the preset conditions, the target node is determined to be the communication master node.

[0043] Therefore, in this application, when the slave node meets the startup duration condition and the number of communication master nodes among all other nodes is 0, the target node successfully competes for master status and becomes the communication master node. The target node can also be designated as the communication master node by other communication master nodes. After the target node becomes the communication master node, it will change the status information of the slave node from communication slave node to communication master node.

[0044] However, during the bidding process, multiple communication master nodes may exist simultaneously. Therefore, in some embodiments, the method further includes:

[0045] Step S51: When the number of other nodes is 1, obtain the self node status of the target node.

[0046] Step S52: When the self-node is in the state of a communication master node, issue a communication master node conflict warning.

[0047] In some embodiments, the method further includes:

[0048] Step S53: When the target ID information and the self-node ID information are different, obtain the self-node status of the target node.

[0049] Step S54: When the self-node is in the state of a communication master node, issue a communication master node conflict warning.

[0050] If the number of communication master nodes obtained directly is greater than or equal to 2, it indicates that a communication master node conflict has occurred, and a communication master node conflict warning needs to be issued. If the target node detects that the number of its own nodes is 1 or that the target ID information in the control transfer information is different from the node ID information, it will not directly determine that the own node is a communication slave node. It also needs to obtain the status of the own node. If the status of the own node is a communication master node, a communication master node conflict warning is issued. Although when the number of connected nodes is greater than or equal to 3, at least one node will be able to discover the existence of multiple communication master nodes, when the number of nodes is equal to 2, it is impossible to determine whether a communication master node conflict exists without confirming the status of the own node.

[0051] When a conflict occurs between communication master nodes, manual intervention is required to transfer control permissions, specifically transferring the permissions of certain communication master nodes to a single communication master node, thus ensuring that the communication master node is unique.

[0052] After determining that the target node is a communication slave node, the method further includes:

[0053] Step S61: When the self node is in the state of a communication slave node, determine that the target node is a communication slave node.

[0054] Step S62: Lock the control interface of the target node.

[0055] Since slave nodes do not have control over the execution device, their control interfaces need to be locked, while the control interface of master nodes is operable. Furthermore, for several conflicting master nodes, the control interfaces of those conflicting master nodes are also locked.

[0056] To better understand the logic for determining the communication master node and communication slave node in this application, such as Figure 2 As shown in the diagram, this application proposes a logical block diagram for determining the communication master node and communication slave nodes.

[0057] This invention addresses the single-source control technology in multi-node communication, primarily through two innovative aspects: 1) It employs multicast communication to exchange state information between nodes, with each node using distributed computing to determine its master-slave status. This innovatively proposes a closed-loop control management technology, avoiding the potential theft of account permissions and the additional overhead associated with account information maintenance in traditional methods; 2) The control transfer management design flexibly allocates the master-slave status of each node in the multicast domain as needed, meeting the requirements of specific application scenarios.

The second acquisition module is used to acquire the current other-node information sent by other nodes from the communication terminal. The first judgment module is used to determine whether the target node meets the preset conditions based on the current self-node information and the current other-node information.
