Abstract

[0002] The digital rod control system is a crucial component of a nuclear power plant's control system. By adjusting the current level and timing of the control rod drive's coil assembly, it controls the raising and lowering of the control rods, thereby regulating reactor reactivity and controlling plant power. The control rod drive's coil current curve clearly reflects the sequence and coordination of the mechanism's moving and retaining hooks, enabling monitoring of the control rod drive mechanism through analysis of the coil current curve.
[0003] Existing CRDM monitoring methods typically process data from a database using current graphing software and visually display it as a current curve within the software interface. When a CRDM operation problem occurs, the current curve can be used to analyze the cause and locate the fault. However, existing CRDM monitoring methods rely solely on manual analysis of the occurrence time of sequential time points, the appearance time of pits, and the degree of hook action delay. Automated monitoring of the CRDM is not possible, resulting in poor CRDM monitoring accuracy. Summary of the Invention

[0034] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
[0035] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0036] The digital rod control system's main components include a rod control logic cabinet, a rod control power supply cabinet, and corresponding application servers. The power plant control system monitors reactor temperature and power levels and sends control rod movement signals to the rod control logic cabinet. The rod control logic cabinet responds to these signals by providing a periodic, timed current to the control rod drive mechanism via the rod control power supply cabinet, thereby raising or lowering the control rods. Figure 1 This is a schematic diagram of data transmission between the rod-controlled power cabinet and the application server in the prior art, such as Figure 1 As shown, the control rod drive mechanism coil loop current passes through the rod control power cabinet signal buffer card, the rod control power cabinet current regulation card and the switch inside the rod control power cabinet, and is finally transmitted to the application server database in the form of data for storage.
[0037] Example 1
[0038] Figure 2This is a flow chart of a control rod drive mechanism performance monitoring method provided by the first embodiment of the present invention. This embodiment is applicable to the case of improving the accuracy of monitoring the control rod drive mechanism. The method can be executed by a control rod drive mechanism performance monitoring device. The device can be implemented by software and / or hardware and can generally be directly integrated into an electronic device that executes the method. The electronic device can be a terminal device or a server device. The embodiment of the present invention does not limit the type of electronic device that executes the control rod drive mechanism performance monitoring method. Specifically, Figure 2 As shown, the control rod drive mechanism performance monitoring method may specifically include the following steps:
[0039] S210: Acquire current signal data of the control rod drive mechanism to be monitored, and determine card component current data corresponding to different card component types of the current regulating card according to the current signal data.
[0040] The CRDM to be monitored may be any CRDM requiring performance monitoring. The current signal data may be current data of a coil assembly of the CRDM to be monitored. The card current data may be current data for different card types.
[0041] In an embodiment of the present invention, current signal data of a control rod drive mechanism to be monitored is acquired, and card current data corresponding to different card types of a current regulating card is determined based on the current signal data. It should be understood that acquiring current signal data of the control rod drive mechanism to be monitored may involve acquiring current signal data of a group of control rod drive mechanisms to be monitored, or acquiring current signal data of the control rod drive mechanisms to be monitored over a period of time, and the embodiment of the present invention is not limited thereto.
[0042] S220 : Determine the current change timing points corresponding to different card types according to the current data of each card.
[0043] Among them, the current change timing point can be the time point at which the current actually changes. It should be noted that the current change timing point can be the time point at which the current data changes, or the time point at which the current trend changes, etc., and the embodiments of the present invention are not limited to this. It is understandable that the current change timing point can be one or more, and the embodiments of the present invention are not limited to this. The change in current trend can be a situation where the current data decreases under the trend of increasing current data, or a situation where the current data increases under the trend of decreasing current data.
[0044] In an embodiment of the present invention, after determining the card current data corresponding to different card types of the current regulating card based on the current signal data, the current change timing points corresponding to the different card types can be further determined based on the current data of each card. It can be understood that the current change timing points corresponding to different card types correspond to the card current data corresponding to the different card types. Exemplarily, if the current regulating card includes card type A and card type B, then determining the current change timing points corresponding to different card types based on the current data of each card may include determining the current change timing points corresponding to card type A based on the card current data corresponding to card type A, and determining the current change timing points corresponding to card type B based on the card current data corresponding to card type B.
[0045] S230. Determine, according to each of the current change timing points, a control rod movement direction corresponding to each of the current change timing points.
[0046] The control rod movement direction may be lifting or inserting the control rod.
[0047] In an embodiment of the present invention, after determining the current change timing points corresponding to different card types based on the current data of each card, the control rod movement direction corresponding to each current change timing point can be further determined based on each current change timing point. It will be understood that the control rod movement direction corresponding to the current change timing points corresponding to different card types also corresponds to different card types. That is, if the current regulation card includes card type A and card type B, then card type A corresponds to the card current data, current change timing points, and control rod movement direction of card type A, while card type B corresponds to the card current data, current change timing points, and control rod movement direction of card type B.
[0048] S240: Monitor the performance of the control rod drive mechanism to be monitored according to each current change timing point and each control rod movement direction.
[0049] In an embodiment of the present invention, after determining the control rod movement direction corresponding to each current change timing point according to each current change timing point, the performance of the control rod drive mechanism to be monitored can be further monitored according to each current change timing point and each control rod movement direction.
[0050] The technical solution of this embodiment obtains current signal data of the control rod drive mechanism to be monitored, determines card current data corresponding to different card types of the current regulating card based on the current signal data, and determines current change timing points corresponding to different card types based on the current data of each card, so as to determine the control rod movement direction corresponding to each current change timing point based on each current change timing point, thereby performing performance monitoring of the control rod drive mechanism to be monitored based on each current change timing point and each control rod movement direction. This solves the problem of poor monitoring accuracy caused by the inability to achieve automatic monitoring in existing control rod drive mechanism monitoring methods, and can automatically monitor the control rod drive mechanism, thereby improving the monitoring accuracy of the control rod drive mechanism.
[0051] Example 2
[0052] Figure 3 This is a flow chart of a control rod drive mechanism performance monitoring method provided in the second embodiment of the present invention. This embodiment is a further refinement of the above-mentioned technical solutions, and provides a variety of specific optional implementation methods, including determining the card current data corresponding to different card types of the current regulating card based on the current signal data, determining the current change timing points corresponding to different card types based on each card current data, determining the control rod movement direction corresponding to each current change timing point based on each current change timing point, and determining the pit appearance time corresponding to different card types based on each card current data. The technical solution in this embodiment can be combined with the various optional solutions in one or more of the above-mentioned embodiments. Figure 3 As shown, the method may include the following steps:
[0053] S310: Acquire current signal data of the control rod drive mechanism to be monitored, and determine card current data corresponding to different card types of the current regulating card according to the current signal data.
[0054] Optionally, before determining the card current data corresponding to different card types of the current regulator card based on the current signal data, the current signal data can be converted to obtain floating-point current signal data. It will be appreciated that when storing the current in the coil assembly of the control rod drive mechanism in the database, the current needs to be converted to binary data for storage.
[0055] Optionally, determining the card current data corresponding to different card types of the current regulation card based on the current signal data may include: obtaining the card identification of the current signal data; when the card identification is divisible by a first set value, determining the current signal data as the current data corresponding to the lifting coil current regulation card; when the card identification is divisible by a second set value, determining the current signal data as the current data corresponding to the holding coil current regulation card; when the card identification is not divisible by the first set value and is not divisible by the second set value, determining the current signal data as the current data corresponding to the moving coil current regulation card.
[0056] The card identifier may be an identifier in the current signal data used to characterize different card types. It is understandable that the card identifier may be one or more bits of data in the current signal data used for identification. The first set value may be a set value. The second set value may be another set value. It should be noted that the first set value and the second set value may be set to different values based on the specific parameters of the current regulation card, and the embodiments of the present invention are not limited to this.
[0057] The lifting coil current regulating card may be a lifting coil current regulating card, the holding coil current regulating card may be a holding coil current regulating card, and the moving coil current regulating card may be a moving coil current regulating card.
[0058] Specifically, current signal data of the control rod drive mechanism to be monitored is obtained, along with a card identifier for the current signal data, and a determination is made as to whether the card identifier is divisible by a first set value and a second set value. If the card identifier is divisible by the first set value, the current signal data can be determined as current data corresponding to the lifting coil current regulation card. If the card identifier is divisible by the second set value, the current signal data can be determined as current data corresponding to the holding coil current regulation card. If the card identifier is not divisible by either the first set value or the second set value, the current signal data can be determined as current data corresponding to the moving coil current regulation card.
[0059] Optionally, after determining the card current data corresponding to different card types of the current regulating card according to the current signal data, the method may further include: determining current waveforms corresponding to different card types according to the card current data corresponding to different card types.
[0060] Specifically, after determining the card current data corresponding to different card types of the current regulating card according to the current signal data, the current waveforms corresponding to different card types may be further determined according to the card current data corresponding to different card types.
[0061] S320: Determine the current change timing points corresponding to different card types based on the current data of each card.
[0062] Optionally, determining the current change timing points corresponding to different card types based on the current data of each card may include: determining the card current slope corresponding to at least one current sampling time point based on the current data of each card under different card types; determining the current sampling time point as a candidate current change timing point when the positive and negative signs of the card current slope corresponding to the current sampling time point are different from the positive and negative signs of the card current slope corresponding to the previous current sampling time point; obtaining a set number of spare current sampling time points after the candidate current change timing point based on the time sequence of the current sampling time points; determining the candidate current change timing point as the current change timing point corresponding to the different card types when the positive and negative signs of the card current slope corresponding to each spare current sampling time point are determined to be the same as the positive and negative signs of the card current slope corresponding to the candidate current change timing point.
[0063] The current sampling time point may be the time point at which current data is sampled. The card current slope may be the slope of the card current data corresponding to the current sampling time point in the current waveform. The candidate current change timing point may be a candidate current change timing point. It is understood that if set conditions are met, the candidate current change timing point may be determined as the current change timing point. The backup current sampling time point may be a time point that is later in time sequence than the candidate current change timing point.
[0064] Specifically, after determining the card current data corresponding to different card types of the current regulating card based on the current signal data, the card current slope corresponding to at least one current sampling point can be further determined based on the current data of each card under different card types, and it is determined whether the positive and negative signs of the card current slope corresponding to the current sampling point are the same as the positive and negative signs of the card current slope corresponding to the previous current sampling time point. If the positive and negative signs of the card current slope corresponding to the current sampling point and the previous current sampling point are different, it means that the current waveform changes from rising to falling, or from falling to rising, and the current sampling time point can be determined as a candidate current change timing point. If the positive and negative signs of the card current slope corresponding to the current sampling point and the previous current sampling point are the same, it means that the current waveform shows an upward or downward trend, and the current sampling point is not a candidate current change timing point.
[0065] Specifically, after determining the candidate current change timing point, a set number of backup current sampling time points following the candidate current change timing point can be further obtained based on the time sequence of the current sampling time points, and a determination can be made as to whether the positive and negative signs of the card component current slopes corresponding to each backup current sampling time point are the same as the positive and negative signs of the card component current slopes corresponding to the candidate current change timing point. If the positive and negative signs of the card component current slopes corresponding to all backup current sampling time points and the candidate current change timing point are the same, indicating that the current waveform is showing an upward or downward trend, the candidate current change timing point can be determined as the current change timing point.
[0066] The above technical solution can eliminate interference current data and improve the accuracy of control rod drive mechanism monitoring by comparing the positive and negative signs of the card component current slope corresponding to a set number of spare current sampling time points after the candidate current change timing point with the positive and negative signs of the card component current slope corresponding to the candidate current change timing point.
[0067] Optionally, before determining the current change timing points corresponding to different card types based on the current data of each card, the current data of each card may be filtered.
[0068] S330. Determine, according to each of the current change timing points, a control rod movement direction corresponding to each of the current change timing points.
[0069] Optionally, determining the control rod movement direction corresponding to each current change timing point based on each current change timing point may include: obtaining the timing point time difference between each current change timing point and the set timing point; when it is determined that the timing point time difference is less than a set time threshold, obtaining the control rod movement direction corresponding to the set timing point, and determining the control rod movement direction corresponding to the set timing point as the control rod movement direction corresponding to the current change timing point.
[0070] The set timing point may be a preset time point at which the current changes, the timing point time difference may be a time difference between two timing points, and the set time threshold may be a threshold corresponding to the preset time difference.
[0071] Specifically, after determining the current change timing points corresponding to different card types based on the current data of each card, the time difference between each current change timing point and the set timing point can be further obtained, so as to obtain the control rod movement direction corresponding to the set timing point when the timing difference is less than the set time threshold, thereby determining the control rod movement direction corresponding to the set timing point as the control rod movement direction corresponding to the current change timing point.
[0072] S340: Determine the pit appearance time corresponding to different card types according to the current data of each card.
[0073] The pit appearance time may be the time when the current waveform falls and then rises again during the rising stage of the current waveform.
[0074] In the embodiment of the present invention, the pit appearance time corresponding to different card types can be determined based on the current data of each card. Figure 3 It is only a schematic diagram of an implementation method. There is no order relationship between steps S320-S330 and step S340. Steps S320-S330 can be implemented first, and then step S340, or step S340 can be implemented first, and then step S320-S330. They can also be implemented in parallel or one of them can be implemented selectively.
[0075] Optionally, determining the pit appearance time corresponding to different card types based on the current data of each card may include: determining the current rise time period corresponding to different card types based on the current data of each card; determining the current slope change rate within each current rise time period; and determining the time point corresponding to the minimum value of the current slope change rate as the pit appearance time.
[0076] The current rising time period may be a time period in which the current waveform presents an upward trend, and the current slope change rate may be a change rate of the current waveform slope.
[0077] Specifically, the current rise time period corresponding to different card types is determined based on the current data of each card, and the current slope change rate within each current rise time period is determined, so as to determine the time point corresponding to the minimum value of the current slope change rate as the pit appearance time.
[0078] S350: Monitor the performance of the control rod drive mechanism to be monitored according to each current change timing point, each control rod movement direction, and each pit appearance time.
[0079] In this embodiment of the present invention, after determining the pit occurrence times corresponding to different card types based on the current data of each card, the performance of the control rod drive mechanism to be monitored can be further monitored based on the current change timing points, control rod movement directions, and pit occurrence times. It will be understood that different types of current regulating cards correspond to different current change timing points, control rod movement directions, and pit occurrence times.
[0080] Optionally, the performance of the control rod drive mechanism to be monitored is monitored based on each current change timing point, each control rod movement direction, and each pit appearance time. The performance of the control rod drive mechanism to be monitored can be monitored based on the current change timing points, control rod movement directions, and pit appearance times corresponding to different types of card components. The performance of the control rod drive mechanism to be monitored can also be monitored based on the current change timing points and pit appearance times corresponding to the control rod movement directions of different types of card components.
[0081] Optionally, the method may also include: determining the current waveform as an abnormal current waveform when the time difference between the current change timing point and the set timing point is greater than the set time threshold, and / or when the current slope change rate does not have a minimum value within the current rising time period of the card current data.
[0082] Specifically, if the time difference between the current change timing point and the set timing point is greater than a set time threshold, the current waveform can be determined to be an abnormal current waveform. It is understood that if the actual current change time point differs significantly from the set current change time point, it indicates a problem with the control rod drive mechanism and the current data is incorrect, and the current waveform is abnormal. If the current slope rate of change does not have a minimum value during the current rise time period of the card current data, the current waveform can be determined to be abnormal. It is understood that if the control rod drive mechanism is operating normally and the current data is correct, the current waveform will definitely have a minimum value point for the current slope rate of change. If the current waveform does not have a minimum value point for the current slope rate of change, it indicates a problem with the control rod drive mechanism and the current data is incorrect, and the current waveform is abnormal.
[0083] The technical solution of this embodiment obtains current signal data of the control rod drive mechanism to be monitored, determines card current data corresponding to different card types of the current regulating card based on the current signal data, and determines current change timing points corresponding to different card types based on the current data of each card, thereby determining the control rod movement direction corresponding to each current change timing point based on each current change timing point, and determining the pit appearance time corresponding to different card types based on the current data of each card, thereby monitoring the performance of the control rod drive mechanism to be monitored based on each current change timing point, each control rod movement direction, and each pit appearance time, thereby solving the problem of poor monitoring accuracy caused by the inability to achieve automatic monitoring in existing control rod drive mechanism monitoring methods, and being able to automatically monitor the control rod drive mechanism, thereby improving the monitoring accuracy of the control rod drive mechanism.
[0084] Example 3
[0085] To help those skilled in the art better understand the CRDM performance monitoring method of this embodiment, a specific example is provided below to illustrate the method. The CRDM performance monitoring method is implemented by combining a CRDM operating current analysis algorithm with CRDM human-computer interaction software.
[0086] Specifically, the control rod drive mechanism action current analysis algorithm includes current big data processing, current filtering algorithm, current separation algorithm, timing point recognition algorithm, pit detection algorithm and control rod movement direction judgment algorithm.
[0087] (1) Current big data processing algorithm:
[0088] Perform big data analysis and processing on imported databases, batch-parse current data, and store the parsed data in the database for later access. The current big data processing algorithm can analyze the current waveform of a control rod drive mechanism, performing trend analysis on the time of pitting, current timing, and control rod movement direction.
[0089] (2) Current filtering algorithm:
[0090] The current filtering algorithm can filter the current data in the database to filter out interference current.
[0091] (3) Current separation algorithm:
[0092] The current separation algorithm can be implemented by judging the identifier of the current regulating card. The filtered current is separated by the current separation algorithm. Specifically, the card type of the current regulating card corresponding to each current is judged by the current ID (identifier), wherein the card types include: MG (moving claw coil), SG (holding claw coil) and LC (lifting coil). For example, the CRCID (current identifier) corresponding to each current regulating card is divided by 16 and 2 respectively. If the CRCID is divisible by 16, the current regulating card type is determined to be LC. If the CRCID is divisible by 2, the coil current type is determined to be SG. If it cannot be divided evenly, the current regulating card type is determined to be MG.
[0093] (4) Timing point recognition algorithm:
[0094] The timing point identification algorithm can be implemented through difference trend judgment. By calculating that the difference between two adjacent sampling points is greater than the set value N times continuously, the timing point at which the actual current changes is calculated, and then the timing point is judged and stored in the database.
[0095] Specifically, the filtered coil current undergoes data conversion, and the slope calculation is performed on the parsed floating-point format tuple. The current slope calculation is performed every 15 time points, and the timing point is determined by the positive or negative current slope and the difference between the slope and the five set points.
[0096] (5) Pit detection algorithm:
[0097] A pit test, also known as a drive mechanism engagement test (DMED), involves detecting inductance changes in the control rod drive mechanism (CRDM) during operation due to changes in the air gap. This sudden change in inductance produces a clearly visible "short pulse of current," known as a current pit. The presence of a current pit verifies the proper functioning of the CRDM.
[0098] The pit detection algorithm can be implemented through slope detection. The filtered waveform is sampled every 1ms, and the difference between the first and last count points in the sampling band within the sampling time is continuously calculated and stored as the waveform slope. The current waveform state is determined based on the waveform slope within the sampling time, and the pit detection result is then determined to be normal.
[0099] Specifically, the DMED algorithm is used for pit detection. First, the coil current waveform data is stored in the software. The current waveform is filtered and the pit's appearance time is determined based on the slope change during the current rise. The rate of change of the slope of the current data curve during the current rise phase is calculated, and the extreme value of the slope is determined. When the slope reaches its minimum, the pit is detected and the pit's appearance time is stored in the database.
[0100] (6) Algorithm for determining the direction of control rod movement:
[0101] The algorithm for determining the direction of current movement (and thus the direction of control rod movement) is implemented by comparing template current data. The current data, separated by the card type, is processed and calculated based on the card type. The effective current value at each monitoring point is compared with the standard current template value based on the card type. Through a series of numerical calculations, the direction of movement is determined to be either lifting or lowering.
[0102] (7) Current waveform state judgment algorithm
[0103] The current waveform status determination algorithm can be implemented using timing point setpoint judgment. The current signal from the current regulator card is acquired over a period of continuous cycles. The rod bundle type of rod insertion or removal is automatically identified based on the waveform relationship between the MG, SG, and LC current sampling. Specifically, the current rise and fall time points (also known as timing points) are compared with the template current setpoint time points to determine whether the rod is being removed or inserted. If the time points do not match the template current setpoint time points, the waveform is considered abnormal. Alternatively, the current rise and fall time points, combined with the rod bundle current direction, can be used to determine whether the waveform is abnormal.
[0104] The above technical solution can realize the functions of on-site current data analysis and current waveform drawing by matching the corresponding database interface, and can realize quantitative analysis of data such as the appearance time of each time point of the control rod drive mechanism action, the appearance time of the pit, the delay degree of the claw action in any time period, etc., realizes intelligent monitoring of the drive mechanism performance, analyzes and predicts the operation status of the control rod drive mechanism rectifier circuit, and provides important supporting data for system health analysis and new maintenance modes. It effectively solves the problems of manual statistical methods that cannot realize the correct evaluation of the system operation status and the inability to automatically realize the drive mechanism data monitoring, and can realize batch data analysis and status trend monitoring of the control rod drive mechanism.
[0105] Specifically, the control rod drive mechanism human-computer interaction software includes GUI design, account management, database connection, query period selection, data analysis, current waveform plotting, rod group switching, pit detection, and timing point identification. The control rod drive mechanism human-computer interaction software is developed in Python, utilizing the PYQT5 library to develop the human-computer interaction interface. Matplotlib is used to plot and process data images, and pyMySQL is used to implement database interface operations. The control rod drive mechanism human-computer interaction software processes and analyzes data stored in a MySQL database through the database interface, visually displaying the analysis results through charts and numerical displays. Accounts can select data for analysis in the human-computer interaction interface and choose different display modes. Different account types have different operating permissions, and account data is also stored in the MySQL database.
[0106] The above technical solution, through the human-computer interaction software of the control rod drive mechanism, solves the problem that the current current graph recognition software cannot be installed on personal office computers, and the data copy files cannot be read on personal office computers due to database interface mismatch, and the current curve analysis work cannot be separated from the on-site industrial computer.
[0107] Figure 4 Schematic diagram of the architecture of human-computer interaction software for a control rod drive mechanism provided by the third embodiment of the present invention. Figure 4As shown, the control rod drive mechanism human-computer interaction software includes an account management module (such as user management), a data analysis and processing module, a database module, a database interface module, a graphics drawing module and a user interface module (such as user UI).
[0108] The account management module manages account information, including account registration / deregistration, account login, account permission management, and password modification. Upon entering the login interface, the account management module retrieves the current account information from the session control, allowing the account to perform operations based on this information. After the account enters the password and sends a request, the account management module responds to the request, obtains all account parameters, sets the modified information into the object, and finally updates the database and sends the updated results to the account.
[0109] The data analysis and processing module parses the current data in the imported MySQL database into floating-point format, and sends the data to the current separation algorithm module, timing point identification module, control rod movement direction judgment module and pit detection module for processing, so that each module can call and analyze the data.
[0110] The database module is used to create relevant data tables in the MySQL database according to actual needs, and classify and store account management data, rod group data, current waveform data, and detailed information data of the current regulation card without interfering with each other, making it easy to call and modify.
[0111] The database interface uses the pyMySQL library. By configuring the database interface, you can implement functions such as creating databases and tables, inserting data, modifying data, and deleting data. Each data table is related by foreign keys, and SQL statements can be used to implement data filtering and interface communication between different data tables.
[0112] The graphics drawing module is used to draw the corresponding current waveform data on the human-computer interaction interface (i.e., the user interface), and can perform waveform switching, data filtering, data switching, report printing and other functions according to user needs.
[0113] The user interface module uses PyQt to implement human-computer interaction. All manual operations, such as login, query, display, and jump, are performed through the UI display interface. All set functional modules are implemented in the human-computer interaction interface, completely separating the underlying code from the logical display interface. Specific human-computer interaction interfaces include the login interface, the core top view interface, the current waveform query interface, the trend display interface, and the rod group step count display interface.
[0114] (1) Login interface: The specific contents of the account management module are displayed on the login interface. Double-click the software startup icon to initialize the software and the login interface will pop up. Figure 5This is an example diagram of a login interface provided by the third embodiment of the present invention. Figure 5 As shown, the login interface includes an account input box and a password input box. Click the Change Password button in the upper right corner of the Login button to jump to the password modification interface. It should be noted that only administrators can change the password. Ordinary accounts can only log in to view the internal current waveform curve and have no right to change the account password or register or cancel an account.
[0115] (2) Core top view interface
[0116] After the account is successfully logged in, you can jump to the core top view interface. Figure 6 This is an example schematic diagram of a core top view interface provided by the third embodiment of the present invention, such as Figure 6 As shown in the top view of the core, different rod groups are represented by different colors. Clicking any single rod in this interface will enter the rod group current waveform query interface.
[0117] (3) Current waveform query interface
[0118] Figure 7 This is an example diagram of a current waveform query interface provided by the third embodiment of the present invention. Figure 7 As shown, the time control on the left displays the current real-time time. The calendar control or time selection control can be used to select the starting time you want to query. Click the "Click to Query" button, and the time display box below the button will list all valid data of the currently selected rod group within the set time. Click any data in the time display box, and the image display area on the right will draw the data of the rod group at that time into an image. The rod group selection button in the upper left corner of the image display area can freely switch the selected rod group. Click the "Click to Query" button to re-query the valid data of the selected rod group. LC indicates that the card component of the current regulation card is the lifting coil, SG indicates that the card component of the current regulation card is the holding hook coil, and MG indicates that the card component of the current regulation card is the moving hook coil.
[0119] (4) Trend display interface
[0120] In the current waveform query interface, click the "Trend Analysis" button above the image display area to jump to the trend analysis interface of the current rod group. Figure 8 This is an example diagram of a trend display interface provided by the third embodiment of the present invention. Figure 8As shown, the trend display interface has six images. The three images in the first row, from left to right, are the LC coil status trend chart, the MG hook coil status trend chart, and the SG hook coil status trend chart when the control rod movement direction of the current rod group is upward. The three images in the second row, from left to right, are the LC coil status trend chart, the MG hook coil status trend chart, and the SG hook coil status trend chart when the control rod movement direction of the current rod group is downward.
[0121] (5) Stick group step count display interface
[0122] In the current waveform query interface, click the "Rod Group Step Display" button to jump to the current rod group step display interface. Figure 9 This is a schematic diagram of an example of a stick group step count display interface provided by the third embodiment of the present invention. Figure 9 As shown, the rod group step display interface plots the total number of steps of the current rod group rising and falling on the same bar graph, and the numbers on the bar graph can also display the number of steps of the current rod group.
[0123] This technical solution, through data communication between the control rod drive mechanism's human-computer interaction software and a MySQL database, enables on-site data analysis and waveform plotting. It also quantitatively analyzes and generates analytical curves for data such as the occurrence time of each sequential point in the control rod drive mechanism's motion, the time of pits, and the degree of hook movement delay within any time period. This allows for timely understanding of the control rod motion status and, based on the analysis results, determines whether maintenance of the rod control system is necessary to prevent rod drop or emergency shutdowns. Analyzing the control rod drive mechanism's motion curves through computer software improves data analysis efficiency, reliability, and accuracy. Analyzing and predicting the operation of the control rod drive mechanism's rectifier circuit provides important supporting data for system health analysis and new maintenance models.
