[0045] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0046] In one embodiment, as Figure 1 shown, an alarm method for a reactor unit of a nuclear power plant (also called a nuclear power station) is provided, including the following steps:

[0047] S10: When the reactor unit is in the overhaul state, determine all operating modes during the overhaul state.

[0048] A reactor is the heat source in a nuclear power plant. It contains nuclear fuel that can carry out a controllable chain nuclear reaction, continuously releasing energy. The heat energy generated by the nuclear reaction is transferred to the steam turbine through the heat carrier to do work. The steam turbine drives the generator, and the generated electric energy is transmitted to the power grid. Among them, the reactor unit includes multiple reactors.

[0049] Among them, the reactor unit includes different working states and various corresponding operating modes under different working states. The working states of the reactor unit include the normal working state and the overhaul state. It can be understood that at the end of each fuel cycle of a nuclear power plant or nuclear power station, some nuclear materials must be replaced. And, in order to improve the operating ability of the reactor unit in the next fuel cycle, it is necessary to make the reactor unit operate in different operating modes to implement overhauls, including in-service inspections, periodic tests, etc., preventive maintenance and corrective maintenance, etc.

[0050] And the overhaul state of the reactor unit includes multiple operating modes. Exemplarily, the operating modes of the reactor unit in the overhaul state include but are not limited to the following modes: Reactor Completely Discharged (RCD), Refueling Cold Shutdown (RCS), Maintenance Cold Shutdown (MCS), Normal Shutdown with RRA connected (NS / RRA), Normal Shutdown with SG (NS / SG), Reactor in Power (RP), and so on.

[0051] In this embodiment, the working state of the reactor unit is determined in real time. Specifically, the working state of the reactor unit can be obtained by reading system parameters. When the reactor unit is in the overhaul state, all operating modes of the current reactor unit during the overhaul state will be determined.

[0052] Exemplarily, in this embodiment, all operating modes of the reactor unit during the overhaul state include five major modes: RCD mode, RCS mode, MCS mode, NS / RRA mode, NS / SG mode, and RP mode.

[0053] S20: Obtain the key alarm items corresponding to each operating mode among all operating modes, and determine the alarm status corresponding to the key alarm items in real time.

[0054] After determining all operating modes during the overhaul state, the key alarm items corresponding to each operating mode will be determined, and the alarm status corresponding to each key alarm item will be determined. Among them, the key alarm item refers to the system that must be available for the reactor unit in the current operating mode. That is to say, the selection of the key alarm item is the system alarm that must be available for the overhaul state required by the nuclear power plant or the "Operating Technical Specifications" of the nuclear power plant in the current operating mode. For example, if the reactor unit includes systems 1, 2, and 3 that must be available under the "Operating Technical Specifications" in a certain operating mode, then these three systems are the key alarm items. For example, the above key alarm items can be some alarm items such as KIC&KSC (Computer Information and Control System & Main Control Room System), and specific examples are not given here one by one. For alarms that are not listed as key alarm items, the "Operating Technical Specifications" have no requirements for their availability and can be ignored.

[0055] The alarm status of the key alarm item, that is, whether the key alarm item currently reflects an alarm state. When in the alarm state, it can also include the alarm level corresponding to the alarm state.

[0056] That is to say, in this embodiment, the key alarm items and corresponding states corresponding to each operating mode in the RCD mode, RCS mode, MCS mode, NS / RRA mode, NS / SG mode, and RP mode can be determined. Specifically, the alarm status corresponding to the key alarm item can be obtained by reading the relevant system parameters of the system corresponding to the key alarm item, and specific descriptions are not expanded here.

[0057] S30: Render the key alarm items and alarm status corresponding to each of the operating modes, wherein the key alarm items are associated and displayed with the corresponding alarm status.

[0058] After obtaining the key alarm items and alarm statuses corresponding to each operating mode, the key alarm items and alarm statuses corresponding to each of the operating modes will be rendered, where the key alarm items are associated and displayed with the corresponding alarm statuses to associatively display each specific key alarm item and its alarm status.

[0059] It can be seen from this embodiment that when the reactor unit is in the overhaul state, by rendering the key alarm items and the corresponding alarm statuses of each operating mode, the key alarm items can be seen in each operating mode, and it can be known whether an alarm has occurred for the key alarm item through the alarm status. In this way, the operator can quickly know whether the systems that must be available in the current operating mode are normal. When abnormal, the operator can query the relevant parameters of the key alarm item according to the alarm status and make adjustments according to the relevant parameters. For the items without an alarm display, they are not rendered, reducing the operator's querying and searching for key alarm items, that is, the alarm situations of important systems, reducing the recognition difficulty and workload. That is, for the alarms not listed as key alarm items, in this embodiment, they are ignored during rendering, which can greatly save the operator's working time and improve efficiency, and can also reduce the operator's omission of important alarms and the occurrence of safety and quality problems.

[0060] It should be noted that in step S30, that is, rendering the key alarm items and alarm statuses corresponding to each of the operating modes, there can be various rendering and presentation methods to further improve the operator's work efficiency.

[0061] Among them, in one embodiment, as Figure 2 shown, step S30, that is, rendering the key alarm items and alarm statuses corresponding to each of the operating modes, specifically includes the following steps:

[0062] S31: Render the corresponding target alarm display screen for each operating mode, where each target alarm display screen includes a plurality of target sub-alarm display screens.

[0063] S32: In the target alarm display screen corresponding to each operating mode, render the key alarm items and alarm statuses corresponding to each of the operating modes, where the key alarm items of the same type are located in the same target sub-alarm display screen.

[0064] For step S31, in this embodiment, when rendering the key alarm items and the corresponding alarm statuses, the corresponding target alarm display screen will be rendered for each operating mode. Exemplarily, as Figure 3As shown, the corresponding target alarm display screens are respectively rendered for each operation mode, including the target alarm display screen corresponding to the NS / SG mode, the target alarm display screen corresponding to the NS / RRA mode, the target alarm display screen corresponding to the MCS mode, the target alarm display screen corresponding to the RCS mode, and the target alarm display screen corresponding to the RCD mode. It should be noted that in the figure, Item represents the key alarm item, Alarm represents the alarm status, the long rectangle below the Item text represents the specific key alarm item, and the square below the Alarm text represents the alarm status. Different alarm levels can be represented by covering different colors in the square, and no specific limitation is made. Additionally, it should be noted that Figure 3 The square in

[0065] is only a rendering schematic diagram, and there can be various presentation forms in actual applications, and no specific limitation is made. Figure 4 As shown, Figure 4 is the target alarm display screen corresponding to the RCD mode. Figure 4 In the target alarm display screen corresponding to the RCD mode, it includes the target sub-alarm display screen of Storage Pit (spent fuel storage pool), the target sub-alarm display screen of Containment, the target sub-alarm display screen of Supportment, the target sub-alarm display screen of Cooling, and the target sub-alarm display screen of KIC&KSC (Computer Information and Control System & Main Control Room System). In each target sub-alarm display screen of the target alarm display screen corresponding to the RCD mode, it includes the same type of key alarm items and their corresponding alarm statuses. For example, in the target sub-alarm display screen of Storage Pit (spent fuel storage pool), it contains the key alarm items related to the spent fuel storage pool and their specific alarm statuses, while in the target sub-alarm display screen of Containment, it contains the key alarm items related to the radioactive containment of the nuclear power plant and their specific alarm statuses.

[0066] Exemplarily, as Figure 5 shown, it is the target alarm display screen corresponding to the NS / SG mode. Figure 5In the NS / SG mode, the corresponding target alarm display screen also includes the target sub-alarm display screen of the Storage Pit (spent fuel storage pool), the target sub-alarm display screen of the Containment, the target sub-alarm display screen of the Supportment, the target sub-alarm display screen of the Cooling, and the target sub-alarm display screen of the KIC&KSC (Computer Information and Control System & Main Control Room System). In each target sub-alarm display screen of the corresponding target alarm display screen in the RCD mode, it includes the same type of key alarm items and their corresponding alarm statuses. For example, in the target sub-alarm display screen of the Storage Pit (spent fuel storage pool), it contains the key alarm items related to the spent fuel storage pool and their specific alarm statuses, while in the target sub-alarm display screen of the Containment, it contains the key alarm items related to the radioactive containment of the nuclear power plant and their specific alarm statuses.

[0067] In this embodiment, a specific rendering method is proposed, which enhances the feasibility. Corresponding rendering screens are created separately for different operating modes during the major overhaul. In this way, the key alarm items and alarm statuses corresponding to each operating mode are convenient for the operator to check, not easy to miss, and targeted. In addition, in the target alarm display screen corresponding to the specific operating mode, the same type of key alarm items are also classified and rendered to the target sub-alarm display screen, making the alarm situation of the key items more hierarchical and convenient for the operator to check.

[0068] Among them, in one embodiment, step S30 specifically includes: rendering a first alarm display screen and a target empty window. The first alarm display screen contains the key alarm items and alarm statuses in the first target operating mode, and the target empty window floats above the first alarm display screen. Among them, the target control window can render a second alarm display screen in response to user operations. The second alarm display screen includes the key alarm items and alarm statuses in the second target operating mode. The first target operating mode and / or the second target operating mode include multiple different operating modes.

[0069] It should be noted that the first alarm display screen is different from the target alarm display screen in the above embodiment. In the above embodiment, all the key alarm items in a specific operating mode rendered and displayed on the target alarm display screen are directly rendered to the target alarm display screens of all specific operating modes, such as Figure 3As shown, in this embodiment, there are two situations for the first alarm display screen. The first situation: The first target operating mode includes a specific operating mode, such as the RCD mode, and the second target operating mode includes multiple specific operating modes, such as the NS / SG mode, NS / RRA mode, MCS mode, and RCS mode. In this case, the first alarm display screen shows the key alarm items and alarm status in the RCD mode. At this time, the first alarm display screen is equivalent to the target alarm display screen in the RCD mode. The second situation: The first target operating mode includes multiple specific operating modes, such as the RCD mode and NS / SG mode, and the second target operating mode includes multiple specific operating modes, such as the NS / RRA mode, MCS mode, and RCS mode. Or, the first target operating mode includes multiple specific operating modes, such as the RCD mode, NS / SG mode, NS / RRA mode, and MCS mode, and the second target operating mode includes a specific operating mode, such as the RCS mode. In this case, the first alarm display screen shows the key alarm items and alarm status in multiple operating modes. At this time, the first alarm display screen is not equivalent to the target alarm display screen in the RCD mode. The understanding of the second alarm display screen is similar to that of the first alarm display screen, except that the second alarm display screen includes all the key alarm items and alarm status in the second target operating mode.

[0070] In this embodiment, the main differences from the above embodiment include: The second alarm display screen will be rendered and jumped out only when the user responds through the vacant window. The vacant window can be understood as an empty window without rendering specific content. Due to the empty window, it can be suspended and displayed on the first alarm display screen as a response control. When the user operates the vacant window, the key alarm items and alarm status of the second target operating mode (one or more specific operating modes) will be rendered and displayed in the second alarm display screen. It can be understood that as mentioned in the background technology, there are numerous alarms that can be triggered in different operating modes. In some modes, there are as many as four or five thousand alarms. Although the embodiments of the present application can screen out the key alarm items, when the display is not large enough and the number of key alarm items is large, the operator needs to scroll the display page by pulling down or scrolling to view all the key alarm items. In this way, it will lead to cumbersome operations. However, through this embodiment, part of them will be hidden in the vacant window, and part of them will be displayed on the first alarm display screen, greatly reducing the key alarm items and their alarm status that need to be rendered on the first alarm display screen. Another part is hidden in the vacant window, reducing the appearance of multiple pages and the user's need to scroll the page multiple times to query, enabling a more intuitive and convenient understanding of the alarm status, and further reducing the workload of the operator.

[0071] In addition, further, in one embodiment, the first alarm display screen and / or the second alarm display screen includes one or more sub-alarm display screens, and each sub-alarm display screen includes all the key alarm items and corresponding alarm statuses in a different one of the operating modes. That is, when the first alarm display screen or the second alarm display screen includes key alarm items of multiple specific operating modes, the corresponding key alarm items can be rendered for different operating mode levels, and the effect is similar to Figure 3 as shown. However, the first alarm display screen does not render sub-screens corresponding to all operating modes, but only sub-screens of some operating modes.

[0072] In one embodiment, rendering the first alarm display screen and the target empty window includes the following steps: rendering the main navigation interface, where the main navigation interface includes a key alarm item status control; in response to a user's trigger operation on the key alarm item status control, rendering the first alarm display screen and the target empty window. In this embodiment, it is also possible to first render the main navigation interface regarding the overhaul status, and this main navigation interface includes a key alarm item status control; the main navigation interface may also include a control for jumping to other monitoring pages. In response to a user's trigger operation on the key alarm item status control, rendering the first alarm display screen and the target empty window. In this way, the operator can enter the alarm page through the main navigation interface of the overhaul status and obtain the alarm status of the key alarm items.

[0073] In some embodiments, it is also possible to render some general key alarm item sets for each operating mode in the target alarm display screen, or render some general key alarm item sets for each operating mode in multiple sub-alarm display screens of the first alarm display screen or the second alarm display screen, so as to render an RCP main pump alarm screen, an SG monitoring alarm screen, an RCV / RRA pump alarm screen, an RRI / SEC pump alarm screen, a support system alarm screen, a ventilation system alarm screen, etc. in one screen. Through the aggregated screen, it is possible to monitor all required available and general system alarm situations through one screen for one mode, and the practicality and usability in actual applications are relatively high.

[0074] In one embodiment, before step S30, that is, before rendering the first alarm display screen and the target empty window, the method further includes the following steps:

[0075] S40: Obtain the total number of key alarm items corresponding to each operating mode;

[0076] S50: Determine the size of the rendering screen required to render all the key rendering items and corresponding alarm statuses of the operating mode according to the size of the total number of key alarm items corresponding to the operating mode.

[0077] Under different operating modes, the total number of corresponding key alarm items determined will naturally be different. In order to render the screen reasonably, in this embodiment, the total number of key alarm items corresponding to each operating mode will be obtained before rendering, and the size of the rendering screen required to render all key rendering items and corresponding alarm states of the operating mode will be determined. Exemplarily, the size required to render the rendering display screen corresponding to the RCD mode, the rendering display screen corresponding to the RCS mode, the rendering display screen corresponding to the MCS mode, the rendering display screen corresponding to the NS / RRA mode, and the rendering display screen corresponding to the NS / SG mode will be determined. The larger the total number of key alarm items, the more multi-screen space is required, so the larger the total number, the larger the required rendering screen.

[0078] S60: Determine a first alarm display screen and a second alarm display screen according to the size of the rendering screen corresponding to each of the operating modes.

[0079] There can be multiple display modes here. For example, taking the above five modes as an example, one or two operation modes with the smallest rendering screen can be used as the first target operation mode, and their key alarm items and alarm status can be rendered in the first alarm display screen to determine the first alarm display screen. The remaining three operation modes are used as the second target operation mode, and their key alarm items and alarm status can be rendered in the second alarm display screen to determine the second alarm display screen, and there is no specific limitation. In this way, the least important key alarm items can be preferentially rendered for the operator to review.

[0080] In one embodiment, different levels of warning states can also be set during rendering. Specifically, different colored alarm lights can be set as alarm level identifiers, so that different colored alarm lights correspond to different alarm levels. For example, a yellow light is displayed when a certain parameter just exceeds a preset threshold, and a red light is displayed when it seriously exceeds the preset threshold, so that the operator can prioritize querying the relevant parameter conditions according to the alarm level and respond to dangerous situations with high alarm levels in a timely manner.

[0081] In one embodiment, if Figure 6As shown, for the rendered screen in each operating mode, such as the target alarm display screen, the sub-alarm display screen in the first alarm display screen or the second alarm display screen, it is also possible to divide and layout-render the overall functional area according to the "three major nuclear safety functions + support functions", that is, in the order of R (Reactivity), C (Cooling), C (Containment), and S (Supportment). For example, the screen is distributed in an RCCS manner from left to right and / or from top to bottom. Taking the rendered display screen corresponding to the NS / SG mode as an example, the rendered display screen corresponding to the NS / SG mode can be as Figure 6 shown.

[0082] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not imply the order of execution. The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

[0083] In one embodiment, an alarm display device for a reactor unit is provided, and the alarm display device for the reactor unit corresponds one-to-one with the alarm method for the reactor unit in the above embodiment.
