The application provides a construction method of an IEC61850
GOOSE protocol dictionary and a protocol feature
library, and the dictionary construction comprises the following steps: step A1, using an
XML label to represent a protocol field; step A2, taking the
label representing the protocol field
as element content of a Protocol
label, and taking the formed
XML file as a protocol dictionary; the feature
library construction comprises the following steps: step B1, generating a protocol field table according to the protocol dictionary; step B2, defining
multiple function functions according to the characteristics of the protocol field, and constructing a function
function table; step B3, constructing protocol features from multiple angles in combination with the field table and the function
function table, and using feature rules to represent the protocol features, and then storing the feature rules corresponding to the protocol features into different protocol feature rule tables; and step B4, constructing the protocol feature
library based on the protocol field table, the function
function table and the protocol feature rule table; the application provides a protocol
feature extraction scheme of the IEC61850
GOOSE, and provides a unified protocol feature representation method.
