Problems solved by technology

[0003] Since there will be a large number of GOOSE messages on the embedded device, the user information field in the control block structure is used to search through string matching, and when sending to the external function block, it is also necessary to form a string format message and in the function The block side also needs to parse and process the strings. This series of string processing has a great impact on performance and cannot meet the performance requirements of the IEC61850 protocol.

Abstract

The invention relates to a GOOSE (Generic Object Oriented Substation Event) message transmitting and receiving method and device, and solves the problem of time consumption caused by searching a transmitting queue through character string matching, putting data into the queue, matching related pins according to character strings after a corresponding module receives the data, and assigning values to the pins in the prior art. According to the technical scheme provided by the invention, the CCD file is analyzed and processed before the GOOSE message is sent, and the mapping relation between the data and the receiver is established before the message is sent, so that time-consuming operations such as character string matching are avoided, and the message receiving and transmitting efficiency and accuracy can be effectively improved under the condition of large data volume.

Description

technical field [0001] The invention relates to the technical field of power system data transmission, in particular to a method and device for sending and receiving GOOSE messages. Background technique [0002] In the process of processing GOOSE sending and receiving messages in the original IEC61850 protocol, for the content of the message that needs to be parsed, it is first necessary to search for the corresponding mapping relationship through the string according to the user information field in the control block structure, and then according to the corresponding mapping relationship. The data is converted into the corresponding external display data content, and then the data content is processed according to the receiving pin of the external function block, and the format data of the pin name length + pin name + value length + value is sent to the function block. After the function block receives , match specific pins according to the pin name, and store and display t...
