The technical solution adopted in the present invention is as follows：
A kind of data interactive method of distributed IEC61850 communication components, comprises the following steps：
Step 1. increases configuration information in the form of configuration file or configuration database, by IEC61850 data
Reference is mapped to the universal data format with ID.
In IEC61850 standards, object and data are all that level is relatively more with tree structure tissue, are handled to application
Bring inconvenience.The present invention will need interactive IEC61850 data in configuration number between application program and IEC61850 communication components
According to an ID is set in storehouse, this ID can be caused by some physical quantity automatically generating or in application.
When calling IEC61850 communication component interfaces to be communicated, configured data ID is used as mark, it is possible to which reducing should

The timestamp Reference in IEC61850, Category represent the type of the data.The type of the data includes：YX is distant
Letter, YC remote measurements, YK remote controls, YM remote pulses, SG definite values group, SGCB definite value group control blocks etc..
Step 2. realizes that RPC interfaces are adjusted for application program using Protocol Buffer on IEC61850 communication components
With.
IEC61850 communication components can be divided into client component and server component, and they are all transported in independent process
OK, and there can be multiple processes.Realize that RPC interfaces supply application call using Protocol Buffer, reduce IEC61850
The degree of coupling between communication component and application program.
Protocol Buffer abbreviation Protobuf, it is the Data Serialization instrument of GOOGLE Inc.'s exploitation, it is provided
It is a kind of similar to C language define message format language, by the form finished writing in advance define file (filename typically with
.proto end up) utilize the protoc precompilers in Protocol Buffer to be generated after handling to specifying message lattice
Formula serializes and the code of unserializing, supports the language such as C/C++, JAVA, Python, GO.For XML format,
Message data caused by Protobuf serializings can be binary form, therefore coding and decoding efficiency is very high.In addition,
Protobuf additionally provides the grammer for defining Service, and RPC interfaces also can be defined in proto files, passes through
The processing of protoc instruments in Protobuf, can generate program code corresponding to Service, thus data transfer letter
The form of interface function calling is turned to, it is very convenient.
Step 3. is according to the needs of IEC61850 communication functions, each communication component and application program in deployment system.

Tool and application deployment are on same physical computer.So, when RPC call parameters, target is arranged to this
Machine.
2), can be by IEC61850 communication components, database in the case that connection quantity is more, amount of communication data is bigger
Server, configuration tool and application program are separately deployed on different computers, and when RPC is called, target is arranged to
The computer address of respective service is provided.
3) when data volume to be processed may exceed a physical computer disposal ability, it may be considered that will
IEC61850 communication components are divided into multiple examples, and each example is responsible for process part data, and these examples are separately operable
On different physical computers.With the expansion of data scale, it need to only increase the example number of IEC61850 components, you can meet
The needs of data-handling capacity.
Beneficial effects of the present invention：
1. hiding IEC61850 communication details, communication interface is simplified so that IEC61850 application developments and tradition

Brief description of the drawings
Fig. 1 is the system overall architecture schematic diagram of the present invention.
Embodiment
Below in conjunction with the accompanying drawings, embodiments of the present invention are illustrated.
A kind of data interactive method of distributed IEC61850 communication components, comprises the following steps：
Step 1, increase configuration information in the form of configuration file or configuration database, by IEC61850 data
Reference is mapped to the universal data format with ID；
IEC61850 data Reference and ID mapping relations in configuration information, wherein, DataID is the data
ID, AssociationID are the connection belonging to the data, and Reference is the data corresponding in IEC61850 models
Reference, Q are Reference of the Quality Codes in IEC61850 corresponding to the data, and T represents the time corresponding to the data
The Reference in IEC61850 is stabbed, Category represents the type of the data.The type of data includes：YX remote signalling, YC are distant
Survey, YK remote controls, YM remote pulses, SG definite values group, SGCB definite value group control blocks.
In order to facilitate being that IEC61850 data set data ID in batches, a configuration tool can be developed, the configuration tool can
With the database access interface provided by RPC interface interchanges database server, obtain and shown with tree
Total data in IEC61850 models, volume of data can be added in configuration form by way of dragging, then
Batch sets identical value or increment value for a certain row of new addend evidence.
Step 2, using Protocol Buffer realize that on IEC61850 communication components RPC interfaces are adjusted for application program
With；
For example, client Remote Control Interface specified in IEC61850 standards enables the interface to pass through, it is necessary to do following work
RPC realizes distributed call：
1) remote control parameter is defined as follows in file client_service.proto：
2) Remote Control Interface is defined as follows in client_service.proto files：
service ClientService{
Other interface definition are omitted by ... // herein
rpc CtrlSelect(CtrlInfo)returns(MessageError)；
rpc CtrlOperate(CtrlInfo)returns(MessageError)；
rpc CtrlCancel(CtrlInfo)returns(MessageError)；
}
3) the instrument protoc of protobuf offers is provided, uses order " protoc-cpp_out=.client_
After service.proto " precompiles, two codes of client_service.pb.h, client_service_pb.cc are can obtain
File, the C Plus Plus statement of remote control parameter defined above and remote control service interface is contained in the two code files.
The two code files are added in IEC61850 client components and the application program that use this interface.In above-mentioned steps
In, service interface class ClientService generates two C++ classes ClientService and ClientService_Stub, point
Do not used for IEC61850 client components and application program.
ClientService classes realize code (part)：
void ClientService::CtrlSelect(
::google::protobuf::RpcController*controller,
const::JYF61850COP::CtrlInfo*,
::JYF61850COP::MessageError*,
::google::protobuf::Closure*done){
controller->SetFailed("Method CtrlSelect()not implemented.")；
done->Run()；
}
void ClientService::CtrlOperate(
::google::protobuf::RpcController*controller,
const::JYF61850COP::CtrlInfo*,
::JYF61850COP::MessageError*,
::google::protobuf::Closure*done){
controller->SetFailed("Method CtrlOperate()not implemented.")；
done->Run()；
}
void ClientService::CtrlCancel(
::google::protobuf::RpcController*controller,
const::JYF61850COP::CtrlInfo*,
::JYF61850COP::MessageError*,
::google::protobuf::Closure*done){
controller->SetFailed("Method CtrlCancel()not implemented.")；
done->Run()；
}
4) ClientService_Stub classes realize code：
5) RpcChannel classes are derived from, realize its CallMethod function.In RPC interface functions generation caused by Protobuf
In code, calling the CallMethod functions of the outside RpcChannel objects set, that data will be called to be sent to will be called
End.In the RpcChannel classes of derivation, can according to being actually needed using different transmission means, such as TCP/IP, HTTP or
Person is third party's data transmission channel such as ZeroMQ.
6) ClientService classes are derived from IEC61850 client communication components, and proto texts are realized in derived class
Each service interface function defined in part, corresponding IEC61850 operations are completed wherein.For example, in CtrlSelect functions
In sent according to the remote information in CtrlInfo parameters to IEC61850 servers and be remotely controlled the message of selection, and server is returned
The operating result returned is returned by MessageError parameters.Then, the ClientService classes of derivation are instantiated, and is
New example binds a RpcChannel objects can and provides interface service.
7) ClientService_Stub example is created in IEC61850 application programs, and is called when needing
Interface function in ClientService_Stub, it, which is called, by Protobuf automatic sequences and to be sent to IEC61850 and lead to
Believe component, the returned content of interface can be automatically switched in the message structure of return, with calling local function not have difference.
8) C++ template class can be used to carry out further encapsulation to Protobuf RPC mechanism so as in the application
More easily use.We have packed two template class：CRpcClient and CRpcServer.CRPCClient is to RPC visitors
The packaging at family end, CRpcServer is the packaging to RPC service device, wherein having bound CRpcChannel derived class
Object, the information called in the object using network transmission and return information.
The code of invocation component is similar in the application：
" CLITCO01 " in code is the Hostname of IEC61850 client components operation.
By above step, the RPC mechanism provided using Protobuf, in the case where not increasing exploitation complexity, just
The coupling of IEC61850 communication components and application program is reduced.As it was previously stated, Protobuf in addition to supporting C++, is gone back
Support the multilingual such as JAVA, Python, Go, they be all on binary system for the coding of data it is compatible, therefore, as long as
Using identical low level communication mechanism, the language supported using Protobuf, IEC61850 communication components can be called to provide
RPC interfaces, compared to the form of direct interface function call that generally uses is played, substantially increase the scalability of program.
Step 3, the needs according to IEC61850 communication functions, each communication component and application program in deployment system.
As shown in figure 1, it is the system overall architecture schematic diagram of the present invention.IEC61850 communication components (including client with
Server communications component) communicated by network with other modules in each application program and system.Meanwhile IEC61850 client
End communication component may be coupled on multiple IEC61850 servers again；IEC61850 server communications components can be for upper strata
IEC61850 clients (such as scheduling station) connect.
Database server and configuration tool are communicated also by network with IEC61850 communication components, there is provided configuration data is visited
Ask interface etc..
Application program module can be by under the IEC61850 clients outside the acquisition of IEC61850 server communications components
The control command of hair, and call corresponding IEC61850 client components interface that control command is forwarded into what is connected
IEC61850 equipment；Meanwhile application program can also be got by IEC61850 client components the data sent on device or
Item, and it is sent to the main website being attached thereto by IEC61850 server components.
