.proto file；
2) substation data model is imported into transformer station, forms substation data caching, and Data Exchange Model is imported
Main website, form main website data buffer storage；
3) by compiling the .proto files of substation data model, generation transformer station message interface, pass through transformer station
Transformer station's message interface accesses substation data caching；And by compiling the .proto files of Data Exchange Model, generate main website
Message interface, main website is set to access main website data buffer storage by main website message interface；
4) main website data buffer storage is called by the resource identification number of entity object, and main website data is connect by main website message
Mouth is sent to transformer station, while calls substation data to cache by the reference path of entity object, and substation data is led to
Cross Substation Station message interface and be sent to main website.
In S103, the .proto files of transformer station and main website both sides are after Google Protobuf compilings in generation pair
The message interface answered, establish transformer station and associated with main website data access and transmission.By taking tBay message as an example, main website resource identification number
Do not have mRID for preset parameter, by entity object RNTO " Cangzhou Wang Hai stations/35kV.3421 intervals ", main website C/C++ codes
Example is as follows：
tBay BayInstance；
S=socket.socket (socket.AF_INET, socket.SOCK_STREAM)；
BayInstance.set_mRID(114278842306143806)；The resource identification number of // object
BayInstance.set_pathname("S1/V1/Q1/L1")；// quote path
BayInstance.set_name (" Cangzhou Wang Hai stations/35kV.3421 intervals ")；// need the title of renaming
BayInstance.set_parentmRID(113997367329423846)；The resource identification number of // parent object
SendData=BayInstance.SerializeToOstream ()；// bay objects message sequence turned into number
According to stream
s.send(sendData)；// pass through network transmission
Application in substations program retrieves entity object according to path is quoted in substation data model, and by it again
It is named as at " Cangzhou Wang Hai stations/35kV.3421 intervals ".
