Implemented with the other modes in the range of being different from being described herein using other, therefore, protection scope of the present invention is not by under
The limitation of specific embodiment disclosed in face.
SCADE is English Safety-Critical Application Development Environment abbreviation,
It is the Application development environ-ment of a high security.French Ace Te Er technology companys have combined boat when developing SCADE softwares
The affiliate in the fields such as empty electronics, automotive electronics, military aircraft and nuclear power stand control, such as AIRBUS, Schneider
Electric, Dassault Aviation and THALES etc., combining multiple fields will to the difference of embedded software developing
Ask, it is proposed that the automation tools and the respective party science of law of a whole set of high security embedded software developing.SCADE is used
Correct by construction concept, is covered whole from demand to embedded code in embedded software developing
Flow：Requirements Modeling, pattern checking, analog simulation, formal verification, embedded code is automatically generated and document is automatically generated
Deng.
Code building function of the invention based on SCADE, the C language code that forwarding unit is generated by SCADE realizes number
According to forwarding and external offer interface.Buffering area and logical algorithm data field are subjected to bidirectional replication.Pass through offset and data class
Type determines data particular content.
Fig. 1 is refer to, functional steps are as follows：
Engineering staff programs external member using SCADE, and Software Function Design is carried out according to the function drawing of design side.
Carry out the input and output of design data between algorithm function output and input in SCADE functional diagrams using mouse drag connection mode
Corresponding relation.
Complete after functional diagram, turned all functional diagrams according to design side's drawing using the translation function built in SCADE external members
It is changed to the C language code that can be compiled.
The code that SCADE is generated carried out using C language header file and source file the secondary encapsulation of variable.Identify
Size, variable arrangement mode, the types of variables of the C language structure of SCADE generations.And the communication pool for realizing it with C language
Software application DLL is docked.
C code after secondary encapsulation is merged compiling with communication interface code by compiling turns into executable file.
By executable file by being attached to Target Board under lower dress program.
Start internal task scheduling on target device after electricity, call executable file to run adapter Target Board.Pass through communication
Interface receives and dispatches each station data.
Data forwarding function is realized by the covering and reading of buffering area.
Refer to P1C2, P1C2 in Fig. 2, figure is two relay protective scheme series.Two relay protective scheme series pass through one simultaneously
Individual TU1 station is come the convergence and distribution of a data that stand.The data processing method that this patent is introduced is used by TU1 again, by two
The data forwarding of individual relay protective scheme series is to safe display unit (SVDU), gateway station (GW) and engineer station (MTS).
Fig. 3 is refer to, for example：A stations have a variable v to need to stand with D to C stations by TU station simultaneous transmissions.So stood in B
During using SCADE systematic function figures, newly-built three variables As, C, D.Three typess of variables must be consistent.Use below figure connecting line
Mode links three variables：
It can be automatically generated when C language code is generated after connection：
V_out_c=V_in_a；
V_out_d=V_in_a；
Then by secondary encapsulation, two variables of V_out_c and V_out_d are aligned in a buffering area.Again by compiling
Translate and be associated buffering area with communication interface, the buffering area that communication is sent is associated with V_out_ V_out_d, the reception of communication
Buffering area is associated with V_in_a.So it is achieved that one-to-many data assignment.Multi-to-multi and many-one are similarly.
Technical scheme in above-mentioned the embodiment of the present application, at least has the following technical effect that or advantage：
Realize handle nuclear power safe level DCS data when worker workload it is small, technical threshold is low, and efficiency is higher
Technique effect.
