Embodiment Construction

[0086] In the smart substation system, it includes the server and each terminal in the same communication network as the server.

[0087] When at least one monitoring node in the smart substation system shifts, the system will perform the following operations:

[0088] First, after receiving the trigger instruction sent by the monitoring node in the system, the server generates GOOSE messages of at least two data types based on the trigger instruction, wherein one GOOSE message carries a data identifier representing the data type;

[0089] Secondly, the server encapsulates each generated GOOSE message into a data frame, and sends each data frame to each terminal in the communication network;

[0090] Thirdly, after each terminal captures each data frame sent by the server from the communication network, each terminal extracts the GOOSE message carrying the corresponding data identifier from each received data frame based on the data type supported by itself and analyzes it ; ...

Abstract

The invention relates to the field of communication technology, and discloses a method and device for sending GOOSE messages, which are used to ensure the synchronization of subscription messages received by each terminal. The method includes: the server generates at least Two data types of GOOSE messages, one of which carries a data identifier representing the data type; then, the server encapsulates each generated GOOSE message into a data frame and sends it to each terminal in the communication network , so as to trigger each terminal to extract and parse the GOOSE message carrying the corresponding data identifier from each received data frame based on the data type supported by itself. In this way, each terminal will capture at least two data frames of the data type of the GOOSE message carried at the same time, and the terminal can obtain the corresponding subscription message based on the data type supported by itself, ensuring the synchronization of each terminal receiving the subscription message sex.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for sending GOOSE messages. Background technique [0002] In the substation environment of the prior art, after receiving the trigger command sent by the trigger terminal device, the server side sends separately to the local area network the GOOSE message information whose data type is a structure, or the GOOSE message information whose data type is a value, The subscribing terminal device captures corresponding message information from the local area network according to its own message subscription type within a set period. [0003] However, if multiple triggering terminal devices send trigger commands to the server at the same time, and the message subscription types of multiple subscribing terminal devices are different, the following problems will occur if the above technical solution is still adopted: Suppose the server sends a message containing ...
