Abstract

The application belongs to the technical field of control, and particularly relates to a method, a device, a medium, equipment and a program product for determining a communication master node. The method comprises the steps of obtaining current self-node information and preset conditions of a target node, obtaining current other node information sent by other nodes from a communication terminal, determining whether the target node meets the preset conditions according to the current self-node information and the current other node information, and determining the target node to be a communication master node when the target node meets the preset conditions. Each node distributed computation decides own master-slave state, creatively provides a closed-loop control management technology, avoids the problem that the account authority is possibly stolen and the account information is maintained in the prior art to bring additional expense, and only allows one software node to issue execution commands in the using process.

Description

Method, device, medium, apparatus and program product for determining communication master node Technical Field The invention belongs to the technical field of control, and particularly relates to a method, a device, a medium, equipment and a program product for determining a communication master node. Background Multicast technology refers to a network communication in which a single sender corresponds to multiple receivers. By transmitting a single information stream to multiple receivers, network traffic with multiple receivers listening or viewing the same resource at the same time can be reduced. In the existing multicast technology, a control end, a communication end and an execution end form a local area network. The control terminal is used for sending the self node information and the control information to the multicast domain and receiving the node information, the communication terminal is used for carrying out data transmission and distribution according to the address information of the multicast data message, and the execution terminal is used for executing the control command according to the multicast data. When the same control software with a plurality of workstations in a local area network runs, that is, a plurality of control terminals exist, control commands issued by a plurality of control terminals may collide (the situation that the previous command is issued at the same time or the other node is not executed yet and a new command is triggered at the same time) and the execution terminal can be caused to execute disorder. Disclosure of Invention In view of the above technical problems, the present application provides a method, an apparatus, a medium, a device, and a program product for determining a communication master node. The method comprises the steps of obtaining current self-node information and preset conditions of a target node, obtaining current other node information sent by other nodes from a communication terminal, determining whether the target node meets the preset conditions according to the current self-node information and the current other node information, and determining the target node to be a communication master node when the target node meets the preset conditions.
