Decoding method and device for digital substation network message

Abstract

The invention provides a decoding method and a decoding device of a network message of a digital substation. The decoding method of the network message of the digital substation includes: receiving the data message, and parsing the data message so as to obtain the type of the data message; judging whether the data message is an smv message, and if yes, obtaining the length of the smv message, and executing a next step of judging the type of a data head of the smv message and parsing data content according to the type of the data head of the smv message; if the data message is not the smv message, judging whether the data message is a goose message, and if yes, obtaining the length of the goose message, and executing a next step, or if not, not executing operation; if the data message is the goose message, judging the type of a data head of the goose message, parsing data content according to the type of the data head of the goose message, and then executing a next step; judging whether the data content of the smv message or the goose message is completely parsed, and if yes, finishing, or if not, returning. The decoding method and the decoding device of the network message of the digital substation have the advantages of being high in decoding efficiency and improving processing performance.

Description

technical field [0001] The invention relates to the field of substation messages, in particular to a decoding method and device for digital substation network messages. Background technique [0002] Currently, both goose packets and smv packets use ASN.1 encoding. ASN.1 is an ISO / ITU-T standard that describes a data format for representing, encoding, transmitting and decoding data. It provides a set of formal formats for describing the structure of objects, regardless of how the language is implemented and the specific designation of these data, and regardless of what kind of application it is, in any need to send information digitally Everywhere, ASN.1 can send various forms of information (such as audio, video, data, etc.). ASN.1 and specific ASN.1 encoding rules promote the transmission of structured data, especially between applications in the network, which describes the data structure in a way that is independent of computer architecture and language. Therefore, ASN...
