[0033] The following is further explained in detail through specific implementation methods.

[0034] like Figure 1 As shown, the present application provides a full simulation system of a sodium-cooled fast reactor safety-level instrumentation and control system, including:

[0035] The processing layer is used to build an algorithm database containing several algorithm modules, generate control logic configuration analysis information of the associated algorithm database according to the system application function, and convert the control logic configuration analysis information into engineering data;

[0036] The application layer is used to build a display database by calling script programs based on engineering data, and to establish simulation scenarios for display, control and interaction on the client side;

[0037] The service layer is used to analyze the control strategy and configuration characteristics of the reference unit control logic (configuration file, which can be a PDF configuration diagram). The reference unit control logic is parsed through tool software and converted into an engineering drawing file that can be directly applied by the platform according to the text format specification of the RINSIM2.0 platform control logic diagram, thereby improving simulation accuracy and work efficiency.

[0038] In the processing layer, the processing layer receives operation signals, updates the control logic configuration parsing information, and interacts with the application layer in real time.

[0039] As an implementable method, the generation of control logic configuration files can be realized through the parsing module, and the generation of simulation control logic configuration diagram files includes:

[0040] Create a text image library and a module image library to obtain configuration files corresponding to the system application functions;

[0041] Based on the text image library and the module image library, image recognition is performed on each configuration file to obtain control logic configuration analysis information, wherein the control logic configuration analysis information (table) includes algorithm modules, location coordinates, device information, link relationships, etc. called by multiple system application functions.

[0042] The text image library and module image library are pre-configured, which contain several text images and module images that may form configuration files. They are processed using image recognition technology. Any existing image recognition technology can be used, including but not limited to neural networks, target detection algorithms, etc., to identify information including position, text, etc., and generate control logic configuration analysis information. The control logic includes the connection relationship between each algorithm module, such as a combination of one or more relationships such as "and", "or", etc.

[0043] After obtaining the configuration analysis information, in order to adapt it to the Rinsim2.0 platform, data format conversion is required. Specifically, the control logic configuration analysis information is converted into a format using a preset file parsing tool to obtain engineering data, which is a logic diagram text format file applicable to the Rinsim2.0 platform. It can be understood that the format conversion can be achieved through a preset mapping table or a preset conversion formula, or data extraction can be performed according to a preset data type to avoid incompatibility or data errors.

[0044] As an implementable method, a preset file parsing tool is used to convert the format of the control logic configuration parsing information to obtain engineering data, which is a logic diagram text format file that can be applied to the Rinsim2.0 platform.

[0045] As an implementable method, the system application functions include but are not limited to function screen display, gallery display, equipment operation window, trend function, log function, data archiving and query function, instrumentation and control fault function, authority management, fault monitoring and diagnosis function, simulation teaching and control function, interface function, etc.

[0046] As an implementable approach, the algorithm database is constructed by obtaining the algorithm block function description file, which is generated by the development algorithm module.

[0047] The algorithm database includes but is not limited to basic control algorithms, etc. The algorithm module can be obtained by parsing the application function or core scheduling. Optionally, the algorithm database can also be constructed by obtaining the algorithm module function description file and developing the algorithm module. The algorithm module function description file can be obtained in a variety of ways, such as graph algorithm module, encryption algorithm module, and algorithm module for calculating engineering value or point quality.

[0048] In the application layer, the SVDU screen is analyzed, the structural characteristics of the engineering drawing files (and simulation object / scenario database, including static graphics and dynamic graphics) obtained by the service layer are input, and the static drawing information such as pipelines, graphics and coordinates, the calling relationship of dynamic graphics, the configuration variables and parameters of dynamic graphics, etc. in the files are extracted. Furthermore, the logical calculations in the simulation scene (object) can be converted to generate engineering drawing files, SVDU engineering databases, calculation logic and other files that can be directly applied by the Rinsim2.0 platform to realize simulation. The specific simulation scene includes but is not limited to the operation of equipment scenes, process flows, and application functions.

[0049] In the application layer, the display database includes but is not limited to static graphics elements such as pipelines, graphics and coordinates, configuration variables and parameters of dynamic graphics elements, calling relationships of dynamic graphics elements and other information.

[0050] The configuration variables of dynamic graphics are switch quantities, analog quantities and system variables. Each variable consists of an engineering value and a point quality. The application function can be displayed based on the variable. As an example, during the fault feedback process, the graphics element in normal operation appears green, and the graphics element in a fault state appears red. The color change is controlled by the variable (analog quantity).

[0051] In the application layer, it is necessary to form a file for displaying the simulation scene on the client through the call of the script program based on the data and the above control logic. The application layer is also associated with a real-time database, which contains operation objects, scenes, etc. in the simulation scene or other required real-time data. The real-time database also includes an initialization module, an interface management module, a data processing module, and an application function management module to realize data interaction and processing under the application layer. Further, a scheduling main program is set up, and the scheduling main program can be connected to the basic image drawing interface, the primitive (including static primitives and dynamic primitives) interface program, and the data and control logic are stored in the primitive database or the real-time database. The scheduling main program calls the script program to execute the corresponding function or interface operation, data processing, etc., to obtain a file that can finally realize the scene simulation.

[0052] Initialization module, used to initialize simulation data and reset simulation conditions;

[0053] Interface management module, used to realize the data interaction of process data and simulation teaching and control instructions between the service layer and the application layer;

[0054] Data processing module, used to process the internal calculation of Level 2 of the simulation instrumentation and control system;

[0055] Application function management module, used for application layer human-computer interaction interface software development and operation and maintenance.

[0056] As an implementable method, the script program includes an interpreter and an interface part:

[0057] Interpreter, used to interpret and execute script programs;

[0058] The interface part is used to read and write data with the real-time database, and to interact and connect data with configuration elements.

[0059] In this embodiment, Microsoft Visual C++ is used to develop algorithm codes for the simulation platform to call, and Python language is used to develop file parsing tools and configuration tools to parse the image recognition results into logical diagram text format files of the Rinsim2.0 platform, and readable configuration files or vsd files are used as application layer input files to convert them into process screens that can be directly compiled and downloaded by the simulation platform. JAVAScript scripting language is used to develop script programs and encapsulate them.

[0060] As an implementable method, the main program is scheduled to obtain static screen information and perform basic drawing through basic image drawing functions, interact with the real-time database through the graphic interface library program, and interact with the graphic attribute connection library through the graphic interface library program to display the screen; the graphic attribute connection library is encapsulated by a script program.

[0061] Specifically, static picture information is a fixed view or image at a certain moment in the simulation process. This picture does not change with time and is used to show the state of the simulation at a specific time point, providing an intuitive way to visualize the simulation results. In education and training, static pictures can also be used as teaching materials. Static picture information can be directly obtained from a certain address, which may also include some of the above static graphics. The graphics attribute connection library contains the connection / call relationship of each graphics element in the display database, and during user operation or data interaction with other devices, the interface is called to update the data.

[0062] The above-mentioned control logic or script program is used to realize system application functions, which include but are not limited to function screen display, gallery display, equipment operation window, trend function, log function, data archiving and query function, instrumentation and control fault function, authority management, fault monitoring and diagnosis function, simulation teaching and control function, interface function, etc. As an example, the function screen display includes but is not limited to color definition, background color definition, font definition, linearity, etc.; the gallery display includes navigation buttons, page buttons, switch buttons, status indicator lights, fault indicator lights, solenoid valves, locking test equipment, etc., each of which includes a graphic and size; the equipment operation window is an operation panel designed for simulation, the purpose of which is to group the instructions for the operator to operate the simulation object; the equipment status display and control screen includes the switch operation panel, system menu, equipment menu, page buttons, etc. Each button has different functions, which together realize the display and control of the equipment. After clicking on the icon of a device, the operation panel of the device appears in the form of a pop-up window, and the operation panel contains all the control commands and feedback information of the device; the instrument control fault function includes the fault type and the corresponding input signal; the simulation teaching control includes startup, operation, slow mode, loading backtracking, etc., each of which corresponds to an input instruction; the interface function is used to communicate with other devices, and other functions can also realize the dynamic change of some graphics elements in the simulation scene.

[0063] As an implementable method, the application layer receives the operation signal and updates the graphic element attribute connection library through the graphics interface scheduling function, so that the scheduling main program updates the real-time database to update the screen.

[0064] As an implementable method, the full simulation system of the sodium-cooled fast reactor safety level instrumentation and control system also includes interaction with third-party systems / equipment, simulating control strategies such as cascade, feedforward, decoupling, adaptive and predictive control. Including but not limited to equipment running in actual scenarios, such as valves and control switch lights in actual scenarios, for simulating the application of control strategies such as cascade, feedforward, decoupling, adaptive and predictive control in simulation scenarios generated based on the platform. Specifically, the functions of the physical SVDU (safety level display of the sodium-cooled fast reactor safety level instrumentation and control system) software can be simulated based on the use of preset running software, including but not limited to data processing and display, command sending, trend display and other functions, giving users a consistent user experience with the SVDU system.

[0065] Data can be exchanged between the processing layer, application layer and client. Figures 1 to 4 As shown, as an implementable method, the application layer receives the operation signal, updates the graphic element attribute connection library through the graphics interface scheduling function, so that the scheduling main program updates the real-time database to update the screen; and / or, the processing layer receives the operation signal, updates the algorithm module and the control logic configuration parsing information, and interacts with the application layer in real time.

[0066] The communication between the server and the client / third-party system can be achieved through Ethernet. The operation signal can include but is not limited to teaching and control commands, etc. The operation signal can be updated to the client after the application layer interacts with the processing layer, or it can be received and processed by the processing layer and synchronized to the application layer and update the client's display. At the application layer, update the connection relationship of the graphics elements, including but not limited to the graphics element position, graphics element status, graphics element connection, etc., to update the screen. At the processing layer, the algorithm module can be used to process data and adjust the control logic. It should be noted that since the application layer is partially dependent on the output of the processing layer, when the processing layer is updated, it needs to interact with the application layer accordingly.

[0067] As an implementable method, for example, a font modification instruction is sent to the server, which means that the update is implemented in the application layer interface and the basic information of the graphic element is modified. For example, if a button operation instruction is sent to the server, the processing layer needs to output data to the application layer after entering the algorithm module and logic control according to the instruction, so as to adjust the application layer variables and update the client display. It should also be noted that third-party systems include but are not limited to specific equipment, such as nuclear power control systems (valves, buttons, pumps), etc.

[0068] The full simulation system of the sodium-cooled fast reactor safety-level instrumentation and control system is less affected by the actual DCS, has controllable R&D progress, is easy to modify, and can easily implement later demand changes. It meets the requirements in terms of availability, simulation accuracy, response time, maintainability, and information security. The control logic translation tool generated at the processing layer for parsing the control logic and the SVDU screen translation tool generated at the application layer for generating simulation scenarios can ensure the accuracy of the engineering data of the simulation system and improve development efficiency in the subsequent simulator data upgrade.

[0069] This application is used to study the control characteristics of the sodium-cooled fast reactor safety-level instrumentation and control system, which may include a server side and several clients. The server side includes the calculation research of basic control algorithms, combined control algorithms and optimization algorithm modules, the transmission of data between modules, the transmission of quality information, and the interface implementation with third-party systems and equipment, etc. It studies the SVDU software functions (trends, logs, fault monitoring and self-diagnosis, authority management, etc.) and screen configuration characteristics, establishes a simulated DCS control system on the Rinsim2.0 platform, and displays it on the client side.

[0070] The full simulation system of the sodium-cooled fast reactor safety-level instrumentation and control system includes algorithm modules, logical control of data between algorithm modules, etc. It is simulated and displayed on the RINSIM2.0 platform and can also interact with the client or third-party system to realize the application of functions.

[0071] Based on the above-mentioned sodium-cooled fast reactor safety level instrumentation and control system full simulation system, such as Figure 5 As shown, the present application also provides a full simulation method of a sodium-cooled fast reactor safety-level instrumentation and control system, including:
