Description

Technical Field

[0001] This application belongs to the field of nuclear power DCS image analysis technology, and in particular relates to a method for standardized conversion of two-layer images in nuclear power DCS. Background Technology

[0002] The digital control and instrumentation system (DCS) of a nuclear power plant is responsible for monitoring the plant's operational status and ensuring safe reactor shutdown and mitigation during accident conditions. The DCS second-level screen is primarily used to receive and display parameter information from various systems, send control commands, and modify control logic. However, the DCS second-level screen can only be used in specific scenarios within a nuclear power plant, and actual units cannot be used by off-duty operators; furthermore, simulators rarely have available windows due to the urgency of operator training and examinations. To facilitate the use of the DCS second-level screen by personnel in different positions, it is necessary to parse and reconfigure the DCS second-level screen files to construct new DCS second-level operation screen files to meet the business needs of various positions within the power plant.

[0003] The data types and structures contained in the DCS second-layer screen files are incompatible with existing configuration tools, therefore data parsing and conversion are required before execution. However, DCS systems come from different manufacturers and models, and their second-layer screen formats vary; for example, components, screens, and control windows all have different file format definitions. Different file types also contain different data types and structures, such as static appearances, conditional expressions, function scripts, second-layer screen jumps, control window pop-up events, and data mapping ancillary information. Therefore, different DCS second-layer screens require different conversion methods, but current conversion methods cannot automatically convert different types of screens simultaneously, lack reusability, and have low efficiency, making it difficult to meet the requirements. Summary of the Invention

[0004] The purpose of this application is to provide a standardized conversion method for two-layer images in nuclear power DCS, which solves the problems of existing nuclear power DCS two-layer image conversion methods being incompatible with different types of images and having low reusability.

[0038] Compared with existing technologies, the nuclear power DCS two-layer screen standardization conversion method provided in this application has the following advantages:

[0039] The method provided in this application does not directly parse and convert DCS Layer 2 screen files. Instead, it defines a standardized intermediate format, first converting screen files of different structures and types into a unified data structure and format, and then performing configuration work based on this unified format. This approach not only supports different types of screen files, but also allows for the multiple reuse of the constructed configuration controls, offering high reusability. Further completion and mapping are only required in the configuration tool before downloading. The reuse operation is also simple, and even non-professional developers can perform it.

[0042] Figure 2 This is a standardized schematic diagram for different types of DCS two-layer screen files in step S2 of this application. Detailed Implementation

[0043] The following detailed description provides further details on specific implementation methods.

[0044] like Figure 1 As shown in the figure, this application provides a method for standardizing and converting two-layer images of a nuclear power DCS, including the following steps:

[0045] S1. Construct a standardized data structure for configuration. The standardized data structure includes a component part, a data mapping part, and a screen part. Set the corresponding standard format for each part.

[0046] S2. After decomposing and reclassifying the data contained in the DCS Layer 2 screen file, each data is divided into the corresponding part of the standardized data structure, and the data structure is reshaped; the data of each part is converted into the standard format of the corresponding part to obtain standardized DCS Layer 2 data.

[0047] S3. Push the standardized DCS Layer 2 data to the configuration tool for completion and mapping, and then download and run it.

[0048] This embodiment first obtains the DCS file uploaded to the system, parses the file data, and parses the static appearance, event functions, template variables, etc. in the DCS file. Then, it performs translation verification and confirmation, completion and mapping, and event function management on the parsing results. Key information in the file parsing process is recorded and managed. The confirmed and completed DCS translation information is adapted before downloading, and the adapted translation components, screens, control windows, etc. are pushed to the screen configuration tool for download and operation.

[0049] This embodiment defines a standardized intermediate format to convert screen files of different structures and types into a unified data structure and format, and then performs configuration work based on this unified format. This approach not only ensures compatibility with different types of screen files, but also allows for the creation of configuration controls that can be reused multiple times, offering high reusability.

[0055] like Figure 2 As shown, this embodiment divides the DCS second-layer screen into several categories: screen files containing only screens, interactive operation screen files, control window screen files, component files, and control window files. Figure 2 In heterogeneous DCS Layer 2, screen file A contains only the screen itself; screen file B is the interactive operation screen file; screen file C is the control window screen file; component file is the component file; and control window is the control window file. The following details the parsing and conversion process for each type of screen.

[0061] By combining standardized component data, standardized data mapping data, and standardized screen data, standardized DCS layer 2 data is obtained.

[0062] Specifically, the DCS Layer 2 screen file is the interactive operation screen file, and S2 specifically refers to:

[0079] Specifically, S3 includes:

[0080] Modify the data attributes of the standardized DCS Layer 2 data, and configure the system based on the modified standardized DCS Layer 2 data.

[0081] The standardized DCS Layer 2 data after conversion can be reused; only the attributes need to be modified, and even non-professional developers can operate it. For example, the file to be converted can be compared with the previous file, and only the incremental part can be parsed and converted, while the identical parts do not need to be converted again.

[0082] Preferably, this method further includes: logging the DCS Layer 2 screen conversion process. The log records and manages key information during the file parsing process, and facilitates backtracking.
