Description

Technical Field

[0001] This application belongs to the technical field of nuclear power plant instrument control and operation, and particularly relates to a method and system for managing software configuration changes in a sodium-cooled fast reactor. Background Art

[0002] As the control nerve center of a nuclear power plant, the start and stop of equipment and the monitoring of on-site equipment are realized by the operation of software configuration. DCS engineers program and draw based on design drawings and change documents on the DCS software platform, and convert them into configuration pages that can be recognized by the DCS software platform. During the commissioning and maintenance phases of a nuclear power plant, change documents will be issued according to the actual situation of on-site operation. DCS engineers will reprogram and redraw the configuration pages according to the change documents, that is, modify the configuration, which is simply called configuration change. Ensuring the correctness of configuration changes during the change process is crucial for the stability and safety of the power plant. Currently, the following problems have been mainly found during the configuration change process:

[0003] 1. When changing the configuration, carry the paper change design document and then modify the configuration on the DCS software platform. After the change implementation is completed, if the process person in charge wants to know how many times a certain page of the configuration diagram of a certain system has been changed, what has been modified each time, or if it is found that the converted configuration has problems, they need to go to the office system to find the latest version of the design document or change document for the corresponding configuration page of the corresponding system, and then bring the document to the site and compare it with the on-site configuration one by one to check whether the conversion is correct, so as to ensure the correct implementation of the configuration change. This method of checking software configuration not only has a long process and takes a lot of time, but also is prone to missing documents.

[0004] 2. During the implementation of configuration changes, the same configuration diagram will undergo multiple change modifications, and the probability of modification errors is greatly increased. Therefore, the process of software configuration changes must be controllable. What content has been modified and what modules have been modified in each software configuration change on the original basis. If these can be clearly shown, it will be possible to accurately locate, identify, and check whether the content modified in the software configuration change is consistent with the change content on the change design drawing, preventing incorrect modification of other content that does not need to be changed, and greatly improving the accuracy of configuration changes and the convenience of inspection. Summary of the Invention

[0005] The purpose of this application is to provide a method and system for managing software configuration changes in a sodium-cooled fast reactor, realizing the comparison of the content before and after software configuration changes, backing up the latest version of the configuration, and establishing the function of linking software configuration diagrams with design drawings and change documents in the same platform system.

[0006] To achieve the above purpose, this application provides the following technical solutions:

[0007] In a first aspect, the present application provides a method for managing software configuration changes in a sodium-cooled fast reactor, including:

[0008] Step 1: Export the configuration file packages of each control station from the on-site DCS system platform, and compress all control station folders into a compressed package;

[0009] Step 2: Import the compressed package into the database of the developed software change management system. After the background of the software change management system performs compliance detection, store the configuration data in the database;

[0014] According to an embodiment of the present application, the configuration file package includes static configuration pages in PDF format and corresponding configuration information files in XML format. Each control station stores its PDF and XML files in an independent folder.

[0016] According to an embodiment of the present application, taking the folder of each cabinet as a unit, sequentially scan and recognize the PDF configuration diagrams of each cabinet, retrieve the compressed package of the previous version of the configuration data, use the recognition and positioning technology to identify the differences between the currently imported and previous version of the configuration drawings. If the scanned PDF configuration diagram of the currently imported version is the same as the previous version of the PDF configuration Figure 1 page, no processing is performed, and the comparison and recognition result of the previous version is maintained when displaying the configuration; if they are inconsistent, compare the different parts between the currently imported PDF configuration page and the previous PDF configuration page, and mark them with different colors according to the type of modification on the basis of the previous version's scanning and recognition.

[0017] According to an embodiment of the present application, taking a single folder of the cabinet as a unit, scan the currently imported XML file and the XML file of the previous version. If the configuration attributes are modified, obtain the position information of the module on the configuration page and mark the position of the modified module with a specific color box.

[0018] According to an embodiment of the present application, in step 5, after importing the DCS software configuration file, the design drawing, and the FD / SAMA drawing of the change file, extract information matching through PDF recognition technology. If it can be uniquely corresponding, establish the mapping association between the software configuration diagram and the design file FD / SAMA diagram and the change file diagram, so as to realize that opening the software configuration diagram can jump to the corresponding design drawing and display the associated change file.

[0019] In a second aspect, the present application provides a sodium-cooled fast reactor software configuration change management system, including:

[0020] A configuration file export module, which is used to export the configuration file packages of each control station from the DCS system. The file package includes PDF configuration pages and corresponding XML files, and is stored and compressed in folders by control station;

[0021] A configuration data import module, which is used to perform double compliance verification on the file format, version continuity, and parameter threshold of the compressed package, and store it in the database after passing;

[0022] A comparison module, which is used for PDF file scanning recognition comparison and XML file recognition comparison;

[0023] A design file association module, which is used to extract the process system code and page number of the PDF design drawing and the configuration diagram, and establish a hyperlink mapping between the configuration diagram and the design drawing and the change file;

[0024] A visualization output module, which is used to display the configuration diagram with color markings.

[0025] According to an embodiment of the present application, the comparison module includes:

[0026] A PDF image scanning unit, which compares the current and historical version PDF configuration pages and marks them with different colors;

[0027] An XML parsing unit, which detects the modification of the software configuration function module attributes and locates and marks them on the PDF configuration page.

[0028] According to an embodiment of the present application, the design file association module includes:

[0029] A process system code matching unit, which is used to establish the association relationship between the configuration diagram and the design drawing according to the matching rules of the process system code and the drawing page number;

[0030] A change tracking unit for generating a dynamic mapping relationship chain between the configuration diagram version and the change file through the change file number and the modification timestamp.

[0034] Compared with the prior art, the sodium-cooled fast reactor software configuration change management method and system provided by the present application have the following beneficial effects:

[0035] The present application realizes an intuitive display of the differences in software configuration before and after the change, and establishes a link between the software configuration diagram, the design drawing, and the change file. The present application is of great significance for the software change management of newly built nuclear power units.

[0036] The present application overcomes the defect of the prior art that the inspection of the software configuration after the change still stays in finding and obtaining the corresponding design file and change drawing file, and then checking the change content one by one. The process is not only cumbersome but also prone to missing inspections. The present application realizes a comprehensive optimization of the inspection of the software configuration after the change. Through the intelligent file association and automatic comparison function, the inspection process is more efficient and accurate, effectively avoiding the cumbersome process and missing problems, and improving the quality and efficiency of the inspection work.

[0037] The present application overcomes the defect of the prior art that the modified content during the change implementation and programming conversion process cannot be intuitively displayed, and does not have the function of intuitively comparing the software configuration changes before and after the change. The present application can display the modified content during the change implementation and programming conversion process in an intuitive form, provide a clear comparison of the software configuration changes before and after the change, enable the staff to easily master the change details, improve the convenience and accuracy of the work, and greatly improve the efficiency and quality of the software configuration change management.

[0038] The present application also overcomes the defect of the prior art that the software configuration files, design files, and change files of the current power plant are still managed separately or not associated with each other on the same platform interface or system, and the drawings are extremely inconvenient to use. The present application integrates the software configuration files, design files, and change files of the power plant, and establishes a close association on the same platform interface or system, making the use of the drawings extremely convenient, facilitating the staff to quickly obtain and consult relevant information, and improving the work efficiency and collaboration ability. Brief Description of the Drawings

[0039] To more clearly illustrate the technical solution of the present application, the accompanying drawings required for the technical description will be briefly introduced below.

[0040] Figure 1 It is a flowchart of the sodium-cooled fast reactor software configuration change management method provided by the present application;

[0041] Figure 2 It is a schematic structural diagram of the sodium-cooled fast reactor software configuration change management system provided by the present application. Specific embodiments

[0042] The following will be further described in detail through specific embodiments.

[0043] As Figure 1 shown, the embodiments of the present application provide a sodium-cooled fast reactor software configuration change management method, including:

[0044] Step 1: Export the configuration file packages of each control station from the on-site DCS system. The types of configuration files are PDF and XML. The PDF files record the static configuration pages, and the XML files corresponding to the PDFs record the configuration information of the configuration pages in code form. One control station corresponds to one folder, and the PDF and XML files are placed in the folder. Compress the PDF and XML information folders of all exported control stations into a RAR format compressed package.

[0045] Step 2: Import the software configuration compressed package into the sodium-cooled fast reactor software configuration change management system. After uploading the compressed package of the configuration data, the background of the change management system detects, scans the compliance of the configuration data in sequence and imports it into the database of the change management system, and the import is completed.

[0046] Step 3: Taking the cabinet folder as a unit in the background, use the recognition and positioning technology to compare the PDF configuration diagrams with the previous version. If they are the same, no processing is required. If they are different, mark the differences with different colors according to the modification type and retain the marking results of the previous version; for the XML files, if the configuration attributes are modified, obtain the position information of the configuration function module with modified attributes on the configuration page and mark and frame the position of the modified module with a specific color.

[0047] After the import into the database is completed, the background takes the folder of each cabinet as a unit, scans and identifies the PDF configuration diagrams of each cabinet in sequence, then retrieves the compressed package of the previous version of the configuration data, and uses the recognition and positioning technology to identify the differences between the currently imported and the previous version of the configuration drawings. If it is scanned that the currently imported version of the PDF configuration diagram and the previous version of the configuration version PDF configuration Figure 1If they are consistent, no processing is done, and the comparison and recognition results of the previous version are maintained when presenting the configuration display results. If they are inconsistent, the differences between the currently imported PDF configuration page and the previous PDF configuration page are compared, and based on the previous version of the scanned and recognized results, different colors are used to mark the modified parts according to the type of modification. The marked results obtained from the comparison of the previous versions are also retained in the latest version. PDF can only scan and compare the surface of the configuration diagram to identify obvious differences between the two versions of the configuration diagram, such as deletions, additions, etc. Whether there are modifications to the attributes of the modules needs to be identified through the XML file. One PDF configuration page of the control station corresponds to one XML file, and the XML file contains the attribute information and tag names of the modules in the PDF configuration page. Similarly, taking the individual folder of the cabinet as a unit, the currently imported XML file and the previous XML file are scanned. If there are modifications to the configuration attributes recorded in the XML, the position information of the modified configuration function modules in the configuration page is obtained, and the positions of the modified modules are marked and framed with a specific color.

[0048] Step 4: Extract the process system code, drawing page number, page number, etc. of the specific position information in the corresponding PDF file configuration diagram through the position information in the XML file. Usually, the configuration diagrams of the DCS software platform will record the above information at specific positions on the page.

[0049] Step 5: Import the design drawings and change files into the sodium-cooled fast reactor software configuration change management system, extract the process system code and drawing information from the design drawings, and establish the association links between the configuration diagrams and the corresponding design files and change files.

[0050] The FD / SAMA drawings of the design drawings and change files are imported into the sodium-cooled fast reactor software configuration change management system. Through PDF recognition technology, the process system code, drawing type, page number, etc. in the software configuration diagram and the FD / SAMA diagram are extracted. The extracted information is matched with the information of the configuration diagram according to the rules. If the correspondence can be achieved, an association is established between the configuration diagram, the design file, and the change file, so that when opening the imported software configuration diagram, it can be linked and jumped to the corresponding design drawings and related change files.

[0051] Step 6: Result output. Opening the configuration diagram can display the latest version of the configuration diagram. Through configuration comparison, it can be seen that there are special color marks on the configuration diagram, marking the modified places on the page. From the marked colors, it can be seen what types of modifications have been made. And the configuration diagrams of the previously imported versions can be retrieved from the database for switching and viewing. The configuration diagram has established corresponding link relationships with the design file drawings and change files. When viewing the configuration diagram, it can be linked and jumped to its corresponding design drawings through the link, and it can be seen which change files have modified this configuration diagram, and it can be linked and jumped to view the corresponding change files.

[0052] In one embodiment, all the control station PDF and XML information folders are compressed into a RAR-format compressed package. After importing the compressed package into the sodium-cooled fast reactor software configuration change management system and uploading the compressed package of the configuration data, the background of the change management system detects, scans the compliance of the configuration data in sequence and imports it into the database.

[0053] In one embodiment, PDF file scanning, recognition, and comparison: After the import into the database is completed, the background takes the folder of each cabinet as a unit, scans and recognizes the PDF configuration diagrams of each cabinet in sequence, then retrieves the compressed package of the previous version of the configuration data, and uses the recognition and positioning technology to identify the differences between the currently imported and the previous version of the configuration diagrams. If the PDF configuration diagram of the currently imported version is the same as that of the previous version of the configuration Figure 1 version, no processing is performed, and the comparison and recognition result of the previous version is maintained during configuration display. If they are inconsistent, the different parts between the currently imported PDF configuration page and the previous PDF configuration page are compared, and based on the type of modification, they are marked with different colors on the basis of the previous version's scanning and recognition, and the marking results obtained from the comparison of the previous versions are also retained in the latest version.

[0054] In one embodiment, XML file recognition and comparison: PDF can only scan and compare the surface of the configuration diagram to identify the surface differences between the two versions of the configuration diagrams, such as obvious changes like deletion and addition. Whether there are modifications to the attributes of the modules needs to be identified through XML files. One PDF configuration page of the control station corresponds to one XML file, and the XML file contains the attribute information and tag names of the modules in the PDF configuration page. Similarly, taking the individual folder of the cabinet as a unit, the currently imported XML file and the previous XML file are scanned. If there are modifications to the configuration attributes recorded in the XML, the position information of the modified functional module in the configuration page is obtained, and the position of the modified module is marked and framed with a specific color.

[0055] In one embodiment, a link is established among the DCS configuration page - design drawing - change file content. The software configuration file drawings are drawn using programming types, while the design drawings and the drawings of the change files are FD / SAMA diagrams. After importing the DCS software configuration file into the sodium-cooled fast reactor software configuration change management system, the FD / SAMA drawings of the design drawings and the change files are then imported. Through PDF recognition technology, process system codes, drawing types, page numbers, etc. in the software configuration diagram and the FD / SAMA diagram are extracted, and the extracted information of the two is matched. If a unique correspondence can be achieved, a mapping association is established among the software configuration diagram, the design file FD / SAMA diagram, and the change file diagram, so that when the imported software configuration diagram is opened, it can jump to the corresponding design drawing and display the relevant change file for this page.

[0056] In addition, such as Figure 2As shown in the figure, the embodiment of the present application provides a software configuration change management system for a sodium-cooled fast reactor, including:

[0057] A configuration file export module, which is used to export the configuration file packages of each control station from the DCS system. The file packages contain PDF configuration pages and corresponding XML files, and are stored and compressed in folders by control station;

[0058] A configuration data import module, which is used to perform double compliance verification on the compressed package for file format, version continuity, and parameter thresholds, and store it in the database after passing;

[0059] A comparison module, which is used for PDF file scanning recognition comparison and XML file recognition comparison;

[0060] A design file association module, which is used to extract the process system codes and page numbers of design drawings, change drawings, and configuration drawings, and establish hyperlink mappings between configuration drawings and design drawings and change documents;

[0061] A visualization output module, which is used to display the configuration drawings with color markings.

[0062] In one embodiment, the comparison module includes:

[0063] A PDF image scanning unit, which compares the current and historical version PDF configuration pages and marks them with different colors for differences;

[0064] An XML parsing unit, which detects the modification of the function module attributes of the software configuration and locates it to the PDF configuration page for marking.

[0065] In one embodiment, the design file association module includes:

[0066] A process system code matching unit, which is used to establish the association relationship between the configuration drawing and the design drawing according to the matching rules of the process system code and the drawing page number; taking the folder of each cabinet as a unit, scan and identify the PDF configuration drawings of each cabinet in turn, retrieve the compressed package of the previous version of the configuration data, and use the recognition and positioning technology to identify the differences between the currently imported and previous version of the configuration drawings. If the scanned PDF configuration drawing of the currently imported version is the same as the previous version of the configuration version PDF configuration Figure 1 is the same, no processing is done, and the comparison and recognition result of the previous version is maintained when displaying the configuration; if they are inconsistent, compare the different parts between the currently imported PDF configuration page and the previous PDF configuration page, and mark them with different colors according to the type of modification on the basis of the previous version's scanning and recognition;

[0067] A change tracking unit is used to generate a dynamic mapping relationship chain between the configuration diagram version and the change file through the change file number and the modification timestamp. Taking a single folder of the cabinet as a unit, scan the currently imported XML file and the XML file of the previous version. If there are modifications to the configuration attributes, obtain the position information of the module on the configuration page and mark the position of the modified module with a specific color bounding box.

[0068] In one embodiment, the visualization output module includes:

[0069] A hierarchical display unit is used to superimpose or independently display the current version configuration diagram, the historical difference annotation layer, and the independent historical version diagram;

[0070] An impact analysis unit is used to generate a list of associated systems and devices affected by the modification according to the module connection relationship in the XML file.

[0071] The sodium-cooled fast reactor software configuration change management system provided by the above embodiment can implement the technical solutions described in the above method embodiments. The specific implementation principles of the above modules or units can be referred to the corresponding content in the above method embodiments, which will not be elaborated here.

[0072] In summary, in this application, the configuration on the on-site DCS software platform is first exported to generate PDF and XML files. The PDF file records the static configuration page, and the XML file corresponding to the PDF records the configuration information of the configuration page in code form. The PDF file and the XML file are integrated and imported into the change management system in the form of a compressed package. The first imported software configuration file is used as an initial software configuration project. Taking a period of time as a cycle, after implementing changes on-site for one cycle, the changed configuration file on the DCS software is exported again and imported into the change management system as the second version of the software configuration project. During the import process, the system compares the configuration information of the current version and the previous version in terms of the PDF file and the XML configuration information, and specifically marks the modified files, thereby completing the collection and preliminary screening comparison of the software configuration data information of the two versions. Then, import the implemented change files and the current latest version of the design drawings, and realize the link between the software configuration diagram, the design drawings, and the change files through the defined rules. When opening the PDF configuration page for viewing, it can be clearly known which change files the configuration page has been modified based on. By linking to the corresponding design drawings, it can be checked whether the configuration diagram is consistent with the current design drawings. If not, consider upgrading the design drawings or checking whether the configuration has missed a certain change to achieve the consistency of the software configuration diagram, the design drawings, and the change file content.

[0073] The above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered within the protection scope of the present application.
