Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
It should be noted that: like reference numerals and letters denote like items in the following figures, and thus once an item is defined in one figure, no further definition or explanation thereof is necessary in the following figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.
First, an application background of the present application will be described.
As shown in fig. 4, the bus combining unit is a transmitting end, the protecting device is a receiving end, the transmitting end side "I bus protection a phase voltage 2" should correspond to the receiving end side "I bus protection a phase voltage 2", and if yes, the data is determined to be correct, if no, the data is determined to be missing at the opposite end. If the 13 items of port data of the sending end and the receiving end are detected to correspond, the data is complete, if the number of the 13 items is less, the data is not lost, and if the number of the 0 items of data corresponds, the data is no data stream.
In theory, the information of the transmitting port and the receiving port of the SV/GOOSE should be consistent, but how to match these information is a difficulty, because the port descriptions of different devices are not identical, and the SV configuration of the interval merging unit and the protection device is used as an example, as shown in fig. 5, where the interval merging unit is the transmitting end and the protection device is the receiving end. The 2 nd item of line A phase voltage 1 on the merging unit side corresponds to the 2.8 th item of extraction voltage 1, for example, the 15 th item of A phase voltage 1 after switching on the merging unit side corresponds to the 2.2 nd item of A phase protection voltage 1, for example, the 12 th item of A phase current measurement on the merging unit side corresponds to the 2.16 th item of A phase measurement current on the protection device side. Therefore, the port descriptions of different devices are not identical, and the port matching result cannot be determined, so that the problems of inaccurate port matching, inflexibility and the like are caused.
Specific embodiments of the present application are described in detail below based on application background.

103. matching a receiving port meeting a preset condition from at least one receiving port according to the at least one query keyword;
104. and generating a matching result and outputting the matching result.
For example, assuming that the keyword of the line a phase voltage 1 is "line voltage", the matching object is "extraction voltage", when the scanned port describes that the keyword of "extraction" and "voltage" is included at the same time, the matching is successful, and if the keyword is included only or not included, the matching is unsuccessful, and the scanning is continued.
For example, assuming that the keyword of the switched a-phase voltage 1 is "a-phase voltage 1", the matching object is "a-phase voltage 1", and the scanned port description contains the keywords of "a-phase", "voltage" and "1", the matching is successful.
Further exemplary, assuming that the keyword of the a-phase current measurement is "a-phase current measurement", the matching object is "a-phase current measurement", and the scanned port description contains the keywords of "a-phase", "measurement" and "current", the matching is successful. Therefore, the method adopts a keyword fuzzy matching method. And defining keywords and matching rules by taking a transmitting end as a reference, then matching with each receiving end port description one by one, and searching for the best matching value.

a matching module 203, configured to match a receiving port that meets a preset condition from at least one receiving port according to the at least one query keyword;
and the generating module 204 is used for generating a matching result and outputting the matching result.

For example, assuming that the keyword of the switched a-phase voltage 1 is "a-phase voltage 1", the matching object is "a-phase voltage 1", and the scanned port description contains the keywords of "a-phase", "voltage" and "1", the matching is successful.
Further exemplary, assuming that the keyword of the a-phase current measurement is "a-phase current measurement", the matching object is "a-phase current measurement", and the scanned port description contains the keywords of "a-phase", "measurement" and "current", the matching is successful. Therefore, the method adopts a keyword fuzzy matching method.
