Description

Technical Field

[0001] This invention belongs to the field of screen display technology, and in particular relates to an integrated screen display method and system for the main control room of a nuclear power plant based on the concept of layering. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] In existing nuclear power plants, VDU (Vehicle Duty Unit) displays are simplified designs based on the plant's system piping and instrumentation diagrams, meaning they are based on the system's processes. Traditional main control room displays abstract the layout of the actual nuclear power plant's instrumentation and piping diagrams into a single screen. However, due to limitations in monitor size and minimum visibility requirements for legends, the content displayed on each screen is limited. Complete screen information needs to be manually segmented and distributed across different screen windows. Typically, one screen corresponds to some or all of a system's functions. In addition, a small number of cross-system integrated screens are also included.

[0004] When viewing information, existing technologies often involve clicking on device areas or buttons to open sub-windows, viewing information layer by layer. This can easily lead to ineffective operations such as interface switching during monitoring, resulting in a loss of context. A typical example is a single system's display screen, which is manually divided into several sub-screens based on sub-functions. However, there are still related interfaces between these sub-screens. Operators switch back and forth at these interfaces using navigation hotspot buttons as needed, thus establishing flow connections between sub-screens. If the system is large and more finely divided, the workload of "interface management" for searching and switching increases, leading to longer task execution time and a heavier mental burden on operators. Similarly, interfaces between systems and between islands are subject to the same limitations. This poses certain obstacles to the control of cross-system, cross-island, and plant-wide processes and the establishment of contextual awareness.

[0005] This design approach considers both ease of implementation and limitations imposed by existing industrial DCS platforms. However, for operators, there is a contradiction between "massive information and limited display." In the analog control room, all information on the control panel is readily available and continuously visible to the operator; in the digital control room, while the data volume is an order of magnitude larger than in the analog control room, the power plant information is artificially segmented and displayed on different screens due to the limited size of the VDU screen. This leads to several issues affecting operator efficiency and reliability:

[0006] Keyhole effect: Digital control rooms cannot provide the same comprehensive overview of a power plant as analog control rooms. Operators in digital control rooms can only view the plant through the "keyhole" of the VDU (Vehicle Digital Unit) display. Immersed in localized information, operators are prone to misjudging the plant's status or failing to track rapid changes in the plant's condition, resulting in reduced situational awareness.

[0007] Digitalization's human error trap: In analog control rooms, information is fixed in location and non-redundant. However, in digital control rooms, as screens switch, specific information cannot be continuously visible in a fixed location. Furthermore, due to the convenience of digitalization, the same information may appear repeatedly on different screens. This increases the cognitive load on operators and raises the requirements for memory. Performance degradation and errors such as navigational errors, misselection of display screens or equipment, etc., are also being identified.

[0008] The workload of secondary tasks has increased: the digital main control room has nearly a thousand screens, organized according to different categories and levels. Operators need to switch screens to find the screens with the information required for the current task in a timely and effective manner, and click on the equipment area or buttons to open sub-windows to view more auxiliary information or control buttons. The workload of human-machine interface management tasks such as searching and switching has increased for operators. Summary of the Invention

[0009] To overcome the shortcomings of the existing technologies, this invention provides an integrated screen display method and system for the main control room of a nuclear power plant based on a hierarchical concept. Based on the hierarchical display screen design concept, a new process parameter monitoring system is developed through digital technology. By presenting information in a hierarchical and progressive manner, the traditional window switching navigation method is broken, a new information display system is constructed, which improves the safety, reliability and comfort of nuclear power operation and solves the problems associated with digitalization.

[0010] To achieve the above objectives, one or more embodiments of the present invention provide the following technical solutions:

[0011] The first aspect of this invention provides a method for integrated screen display in the main control room of a nuclear power plant based on a hierarchical concept.

[0012] A method for integrating the main control room screen of a nuclear power plant based on a hierarchical concept includes the following steps:

[0013] Collect process flow information, piping and equipment layout information, and functional layout information to generate process flow diagrams, piping and equipment layout diagrams, and functional layout diagrams.

[0014] Based on the upstream and downstream relationships of the process flow, and combined with the pipeline and equipment layout diagram and functional layout diagram, the process flow diagram is divided into 7 canvases.

[0015] Following a shift in perspective from macro to micro, variable information granularity is introduced, and the seven canvases are presented in four layers from top to bottom.

[0016] The information at the four levels is divided into multiple groups from multiple dimensions to form selectable information domains;

[0017] Navigation and display of different information domains, levels, and canvases can be achieved based on mouse input commands.

[0018] The second aspect of this invention provides an integrated screen display system for the main control room of a nuclear power plant based on a hierarchical concept.

[0019] A layered integrated display system for the main control room of a nuclear power plant, including:

[0020] The information acquisition module is configured to: collect process flow information, pipeline and equipment layout information, and functional layout information to form process flow diagrams, pipeline and equipment layout diagrams, and functional layout diagrams.

[0021] The canvas division module is configured to divide the process flow screen into 7 canvases based on the upstream and downstream relationships of the process flow and in combination with the pipeline equipment layout diagram and functional layout diagram.

[0022] The hierarchy module is configured to: introduce variable information granularity according to the perspective change from macro to micro, and present the 7 canvases into 4 levels from top to bottom;

[0023] The information domain segmentation module is configured to divide information at four levels into multiple groups from multiple dimensions, forming selectable information domains.

[0024] The navigation and display module is configured to enable navigation and display of different information domains, levels, and canvases based on mouse input commands.

[0025] A third aspect of the present invention provides a computer-readable storage medium having a program stored thereon, which, when executed by a processor, implements the steps of the integrated screen display method for the main control room of a nuclear power plant based on a hierarchical concept as described in the first aspect of the present invention.

[0026] The fourth aspect of the present invention provides an electronic device, including a memory, a processor, and a program stored in the memory and executable on the processor, wherein the processor executes the program to implement the steps in the integrated screen display method for the main control room of a nuclear power plant based on the hierarchical concept described in the first aspect of the present invention.

[0027] The above one or more technical solutions have the following beneficial effects:

[0028] (1) This invention innovatively applies the information organization and interaction method of Geographic Information System (GIS) to the display screen of the main control room of the distributed control system (DCS) of nuclear power plant. It combines the traditional pipeline equipment and functional layout with the segmented canvas design, condensing thousands of display screens in the control room into 7 large canvases, eliminating the keyhole effect, maintaining the dynamic balance of real-time monitoring of the overall status of the nuclear power plant and rapid location of abnormal data alarms, and reducing secondary tasks such as operator screen switching. It is a disruptive optimization of the display screen design concept in the field of industrial control.

[0029] (2) This invention utilizes canvas layering and efficient dynamic rendering technology to divide the canvas into four layers. Through flexible zoom / click switching with the mouse and precise coordinate positioning, it supports operators to achieve efficient positioning and browsing from the overall plant view layer to the detailed system layer through interactive methods such as moving, zooming in and out, and eagle eye view. This is more in line with the operator's natural interaction habits and reduces the secondary task load.

[0030] (3) Based on the operator's cognitive and decision-making model, this invention divides information into multiple groups from multiple dimensions to form selectable information domains. It constructs an information layering and intelligent dynamic following mechanism based on multiple dimensions such as equipment type, pipeline level, process system, different working conditions, accidents, and tasks. This ensures that the most suitable and effective information is provided to the operator at different zoom levels and in specific power plant conditions, thus solving the problem of existing digital human error traps.

[0031] (4) The technical architecture of time-series database and real-time data access system avoids the limitations of conventional GIS system in real-time performance and big data interaction. It can support the bidirectional reading and writing requirements of nuclear power real-time data with high frequency, many measurement points and large amount of information, and meet the requirements of nuclear power for data integrity, correctness and timeliness.

[0032] (5) Through a flexible and open structural design, it avoids the closed nature of conventional DCS interface modules. It not only supports integration with the underlying platform of cross-instrument control, but also can be conveniently integrated with external plant-level monitoring systems and intelligent monitoring platform systems. It can also load elements that traditional working condition platforms do not support, such as special three-dimensional model controls.

[0033] Advantages of additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0041] It should be noted that the following detailed descriptions are exemplary and intended to provide further illustration of the invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0042] It should be noted that the terminology used herein is for the purpose of describing particular implementations only and is not intended to limit the exemplary implementations of the present invention.

[0043] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0044] The overall concept proposed in this invention is as follows:

[0045] The starting point of this invention is to improve the safety of nuclear power operation through field integration and the application of new technologies. It is also an innovative application of GIS technology in the core field of nuclear power operation, with significant social benefits and industry demonstration effect.

[0046] Based on the operator's cognitive and decision-making model, this achievement innovatively applies the information organization and interaction methods of Geographic Information System (GIS) to the display screen of the main control room of the distributed control system (DCS) of nuclear power plants, reducing the number of display screens for the control room operators from nearly a thousand to single digits. The constructed information layering and intelligent dynamic following mechanism based on multiple dimensions effectively ensures information matching and minimizes the frequent switching and information complexity of traditional DCS screens, providing great convenience for nuclear power plant design verification, operation monitoring, auxiliary operation and maintenance, principle demonstration and training.

[0047] In addition to the main control room display, this technology can also be applied to plant-level monitoring systems and smart nuclear power monitoring platforms. It also possesses technical versatility for applications across reactor types and industries.

[0048] In terms of screen layer design: the existing traditional navigation window format process flow screen is divided into 7 canvases according to the upstream and downstream relationships of the process flow, combined with the location and functional layout of pipeline equipment. This avoids excessive fragmentation caused by manual cutting, making information connection and transition smoother and reducing secondary tasks such as screen switching. At the same time, in order to reduce the data complexity of the interface presentation, reasonable variable information granularity is introduced according to the perspective change from macro to micro, presented from top to bottom in four levels: power plant overview, card-style overall view, multi-system integrated screen, and system partial detailed view. Flexible scrolling, panning, and clicking to switch can realize the scaling and movement of the screen, the quick switching between information importance, and precise positioning. In order to avoid information overload caused by the simultaneous presentation of a large amount of information in multiple interfaces, information dimensions such as dynamic / static legends, safety classification, pipeline level, system category, and equipment parameter type are divided. Intelligent filtering and dynamic tracking are performed according to the working conditions to improve the level of human-machine interaction intelligence and operator cognitive performance.

[0049] In terms of platform architecture: the system adopts a hybrid C / S and B / S architecture, providing a unified management interface; it adopts modular modeling technology and object-oriented design methods, and follows the software maturity requirements of CMMI 3; the configuration tools are reliable and flexible, providing visual configuration editing functions, and the layered screens are easy to build and maintain; a high-performance time-series database and message queue are built to meet the system storage and response functions of massive real-time data in nuclear power plants.

[0050] In terms of functionality: A partitioned layer and dynamic navigation are adopted. By establishing an SVG / CIM equipment model, the spatial attributes, equipment attributes, and real-time information of power plant elements are organically integrated, and key equipment is highlighted and abstractly expressed in different layers. At the data display level, asynchronous refresh of equipment elements and monitoring data is implemented, improving the user experience. Based on cross-platform panoramic hybrid rendering technology, the dynamic rendering and graphic expression capabilities of the process system diagram are enhanced, ensuring visualization effects. Display technology based on complex topology rule checks ensures the correctness and standardization of process connections.

[0051] Example 1

[0052] This embodiment discloses an integrated screen display method for the main control room of a nuclear power plant based on a hierarchical concept.

[0053] like Figure 1 As shown, the integrated screen display method for the main control room of a nuclear power plant based on the hierarchical concept includes the following steps:

[0054] Collect process flow information, piping and equipment layout information, and functional layout information to generate process flow diagrams, piping and equipment layout diagrams, and functional layout diagrams.

[0055] Based on the upstream and downstream relationships of the process flow, and combined with the pipeline and equipment layout diagram and functional layout diagram, the process flow diagram is divided into 7 canvases.

[0056] Following a shift in perspective from macro to micro, variable information granularity is introduced, and the seven canvases are presented in four layers from top to bottom.

[0057] The information at the four levels is divided into multiple groups from multiple dimensions to form selectable information domains;

[0058] Navigation and display of different information domains, levels, and canvases can be achieved based on mouse input commands.

[0059] Furthermore, the collection of pipeline equipment layout information specifically includes:

[0060] The system equipment and components are collected to illustrate the operation process and form a pipeline equipment layout diagram.

[0061] The components include pipes, valves, and pumps;

[0062] The layout information for the data collection function is specifically as follows:

[0063] According to the various functional modules of the nuclear power plant system, information on each device that performs the same function is collected, and the information on devices that perform the same function is organized together to form a functional layout diagram.

[0064] Furthermore, the process flow diagram is divided into 7 canvases, specifically: the overall view of the unit, primary circuit, secondary circuit, first auxiliary system, second auxiliary system, safety protection system, and electrical and switch station. The first auxiliary system includes the primary circuit auxiliary system, the waste treatment auxiliary system, and the primary circuit HVAC auxiliary system. The second auxiliary system includes the secondary circuit auxiliary system and the secondary circuit HVAC auxiliary system.

[0065] Furthermore, the main framework of the process flow diagram adopts a pipeline and equipment layout, while some areas adopt a functional layout.

[0066] Furthermore, following the perspective shift from macro to micro, variable information granularity is introduced, and the seven canvases are presented in four layers from top to bottom. These four layers are: power plant overview layer, overall view layer, multi-system / single-system fusion image layer, and system detail layer.

[0067] The power plant overview layer is the first layer, used to display important information;

[0068] The overview layer is the second layer, used to display a condensed card-style overview of a single system;

[0069] The multi-system / single-system fusion screen layer is the third layer, used to display interface information and block information, as well as main pipeline, equipment and parameter information;

[0070] The system partial detail view is the fourth layer, used to display device details and parameter information.

[0071] Furthermore, the information at the four levels is divided into multiple groups from multiple dimensions, including division by layer and division by display elements; among which, division by display elements includes dynamic / static legend classification, safety equipment classification, pipeline type, equipment category and equipment parameter type.

[0072] Furthermore, based on mouse input commands, navigation and display of information fields, hierarchies, and canvases are implemented, specifically including:

[0073] When the mouse input command is to left-click the device symbol navigation, navigation and display of the next level specific device can be achieved;

[0074] When the mouse input command is to scroll the mouse wheel down, the position is positioned at the center of the next layer of the canvas; when the mouse input command is to scroll the mouse wheel up, the position is positioned at the center of the previous layer of the canvas.

[0075] When the mouse input command is to drag or click the left mouse button at the edge of different canvases, navigation and display between different canvases can be achieved;

[0076] When the mouse input command is to select different information fields with the left mouse button, the different information fields are displayed.

[0077] The core idea of ​​this system is to integrate hundreds or even thousands of monitoring interfaces into a few large canvases, transforming interface switching into view transitions within the same canvas. This allows operators to perform most operations within the same canvas, reducing secondary tasks such as screen switching and enabling them to focus more on the current task, thus reducing the difficulty and time spent searching for information on the screen. Simultaneously, flexible keyboard and mouse operations facilitate smooth transitions between different canvases, enhancing the intelligence of human-computer interaction and improving operator cognitive performance and work efficiency.

[0078] (i) The first technical point of the integrated screen display method for the main control room of a nuclear power plant based on the concept of layering in this invention is: a segmented canvas design that combines traditional pipeline equipment and functional layout.

[0079] Piping and equipment layout diagrams are commonly used process simulation diagrams drawn based on the operating principles of nuclear power plants. In addition to showing the large system equipment, the diagrams also label components such as pipes, valves, and pumps to illustrate the operating process. Its advantage is that it is conducive to the detection of the overall status of the nuclear power plant. Once an anomaly is detected, it is easy to locate the faulty area or equipment based on abnormal data or alarms. Its disadvantage is that some monitoring tasks of nuclear power plants require the observation of parameters of multiple different devices. In this case, using this layout will increase the search load.

[0080] Functional layout diagrams are designed based on the layout of various functional modules of a nuclear power plant system, organizing information that performs the same function together. Functional layout is helpful for information retrieval and error diagnosis when dealing with certain functional failures. Its disadvantage is that when data for the same function comes from multiple devices, it is difficult to determine the device that has failed.

[0081] like Figure 2 As shown, based on the characteristics of the Guohe No. 1 nuclear power plant's process system, the entire plant's process flow is divided into 7 canvases. The main framework of the canvas adopts a traditional pipeline and equipment layout, while some areas adopt a functional layout.

[0082] (ii) In order to reduce the data complexity of the interface presentation, it is necessary to monitor the changes in granularity from macro to micro. Therefore, this system proposes the second technical point of screen design: variable information granularity (hierarchy).

[0083] A reasonable information granularity helps improve operators' situational awareness and avoids confusion. This design divides information granularity into four levels, from top to bottom, such as... Figure 3 As shown.

[0084] First layer: Overview (the highest level overview, displaying important information);

[0085] Second layer: Overview window screen (single system condensed card-style overview);

[0086] Third layer: Multi-system / single-system screen (overlapping systems, displaying interface information and block information, main pipes, equipment, and parameters);

[0087] Fourth layer: System partial detailed drawings (including equipment details and parameter information).

[0088] (iii) In order to avoid a large amount of information from multiple interfaces being presented on a single interface without causing information overload, this system proposes the third technical point of screen design: selectable information fields.

[0089] Selectable information domains refer to information being divided into multiple groups based on various dimensions. Operators can choose the information domains to be presented according to the needs of the current context. This prevents unnecessary information from being displayed on the interface and interfering with operations, thus improving information search performance. Therefore, such as Figure 4 As shown, in addition to displaying by layers, it is also possible to divide and display information according to different information layer dimensions based on the displayed elements:

[0090] Equipment with and without measuring points; safety-related and non-safety-related equipment; main process pipelines and auxiliary pipelines; different process systems; parameters and equipment related to different operating conditions (normal operation, different types of accidents, etc.); equipment with alarms and normal equipment; different types of equipment (such as pumps and valves) and parameters (such as pressure, liquid level, temperature, flow rate); post-accident monitoring parameters; equipment and parameters that perform different functions or tasks (sub-functions decomposed based on functional analysis, or sub-tasks obtained from task analysis).

[0091] (iv) How to flexibly switch between different information groups is the key to the system's usability. Therefore, the fourth technical point of this design is proposed here: flexible zoom / click switching and precise coordinate positioning.

[0092] The mouse wheel or interface controls allow for quick switching between different information importance levels. Based on design requirements, the detailed design description for the display and navigation of the four layers (partial system diagram 0-1:400, single system diagram scale 1:400-1:1000, multi-system diagram 1:1000-1:5000, overall view 1:5000-1:7000, and general overview 1:7000-1:10000) is as follows: Figure 5 As shown:

[0093] Layer 1-Layer 2: Users can use the left mouse button to click on the device symbol for navigation and precisely locate the specific device in the lower layer; users can use the mouse wheel to scroll down to locate the center of the lower layer's canvas.

[0094] Layer ② - Layer ①: Users can use the mouse wheel to scroll up to locate the center of the upper layer canvas.

[0095] Layers 2-3: Users can use the left mouse button to click on the device symbol for navigation and precisely locate the specific device in the lower layer; users can use the mouse wheel to scroll down to locate the center of the lower layer's canvas.

[0096] Layer ③ - Layer ②: Users can use the mouse wheel to scroll up to locate the center of the upper layer canvas.

[0097] Layers 3-4: Users can navigate to the next layer's partial system diagram by scrolling down with the mouse wheel from any position on the same canvas, and the graphic display scale is appropriate to meet user requirements; when users are in a partial system diagram layer, the symbols will be enlarged according to the scale by scrolling down with the mouse wheel, and the enlargement will stop after a certain scale is reached, and the user will be prompted "The maximum display scale of this layer has been reached".

[0098] Layers 4-3: In the local system diagram view, users can use the mouse wheel to scroll up to locate the center area of ​​the upper canvas (sub-layer).

[0099] The new concept of display screens integrates all existing process flow screens according to the upstream and downstream layout of the nuclear power plant process into one or several large human-machine interface display screens, avoiding manual segmentation. Traditional interface switching is transformed into interface view transformation within the same canvas. In this invention, operators perform most operations within the same canvas, reducing secondary tasks such as screen switching, allowing operators to focus more on the current task and reducing the difficulty and time spent searching for information on the screen. Simultaneously, flexible keyboard and mouse operations enable smooth transitions between different canvases, improving the level of intelligence in human-machine interaction and enhancing operator cognitive performance and work efficiency.

[0100] The design of this invention adopts a segmented canvas design that combines traditional pipeline equipment and functional layout, achieving a dynamic balance between real-time monitoring of the overall status of the nuclear power plant and rapid location of abnormal data alarms.

[0101] To reduce the complexity of the data presented on the interface, monitoring needs to be carried out according to changes in granularity from macro to micro. Therefore, introducing a reasonable variable information granularity (hierarchy) helps improve the operator's situational awareness and avoid getting lost. Operators can zoom and move the monitoring screen, quickly switch between information priorities, and search for information by scrolling the mouse wheel, dragging the mouse to position, and clicking precisely. This makes information connection and transition smoother, improves the concept of screen information integration and interaction, and enhances the level of human-computer interaction intelligence and operator cognitive performance.

[0102] To avoid information overload caused by displaying a large amount of information from multiple interfaces on a single interface, the new concept screen design divides information into multiple groups from multiple dimensions through selectable information fields. Operators can select the information fields to be presented according to the needs of the current situation, avoiding unnecessary information from being displayed on the interface and interfering with the operation, which is conducive to improving the performance of information search.

[0103] Nuclear power plant control systems handle massive amounts of interactive data, requiring real-time response and storage of the vast amounts of data generated during accident transients. The introduced real-time database features high throughput and low latency, providing high-performance support for rapid insertion and complex queries of time-series data. Furthermore, due to inconsistencies in the refresh frequencies of equipment elements and parameters, and the existence of two different refresh frequencies within the same layer or screen, an asynchronous refresh mechanism for different elements within a single image was established. This mechanism assigns a single thread to elements displayed in real-time, without affecting data transmission on the main thread, thereby enabling asynchronous refresh of different elements within a single image and improving the user experience.

[0104] This invention's platform system adopts a combined C / S and B / S architecture, including a server and a client, providing a unified management backend service program for easier management; the interface and business processing logic are separated, facilitating interface optimization design; and the server-side load is reduced, improving overall operating efficiency. The configuration tool boasts high reliability, availability, and flexibility; layered screens are easy to build and maintain; it employs modular modeling technology and object-oriented design methods, offering better reusability, maintainability, and scalability, supporting continuous improvement of subsequent functions, and facilitating long-term testing, modification, and improvement, reflecting the characteristics of software engineering; it adopts a flexible visual configuration method, providing user-friendly interaction, matrix-style permission control, and a visual configuration and setting approach.
