Description

Technical Field

[0001] This application belongs to the field of fuel assembly transfer technology, specifically relating to a method, device and system for monitoring the transfer status of fuel assemblies, and a wireless crane scale. Background Technology

[0002] Fuel assemblies are the energy source for nuclear power plants. They are not only expensive but also crucial to safety, requiring constant monitoring during transport to ensure they are not damaged. Due to site constraints, operators cannot closely monitor the fuel assemblies, especially during the transfer of new fuel assemblies from their packaging to the spent fuel pool storage compartments. Typically, a crane-mounted hook scale is used to indirectly monitor the condition of the fuel assemblies. Operators determine the normal load fluctuation range based on the type of fuel assembly (different types of related components), and then combine this with the real-time measurements from the hook scale to determine if any abnormalities are detected. If a new fuel assembly scrapes or snags on other equipment, causing the hook scale reading to exceed the normal fluctuation range, an alarm is manually issued to the crane operator, immediately halting transport until the abnormality is resolved, preventing damage to the fuel assembly or minimizing its extent.

[0003] However, the repeated transfers on-site greatly increased the likelihood that anomalies would not be detected in time. There are many types of fuel assemblies, and the normal range of load fluctuations is also wide. Manual memorization or table lookup for judgment is prone to errors. Furthermore, the fuel assemblies are approximately 4 meters long, making the crane scale position inconvenient for reading, and manual visual readings are prone to errors or delays. More importantly, manually issuing anomaly alarms has a certain response delay; the crane operator cannot receive alarm information immediately, thus making it impossible to prevent the fuel assembly damage from worsening. Summary of the Invention

[0004] In view of this, this application provides a method, device and system for monitoring the transfer status of fuel assemblies, and a wireless crane scale. By automatically monitoring the transfer status of fuel assemblies and promptly alarming when abnormalities occur in the operating status of fuel assemblies, the transfer operators can obtain abnormal alarms at the first time, avoid damage to fuel assemblies or reduce the degree of damage, and also reduce the burden of manual operations and the risk of human error.

[0005] The first aspect of this application provides a method for monitoring the transfer status of a fuel assembly, the method comprising: acquiring the load measurement value of the fuel assembly under test; acquiring the alarm value range corresponding to the fuel assembly under test; determining whether the transfer status of the fuel assembly under test is abnormal by combining the load measurement value and the alarm value range; and sending an alarm signal if the transfer status of the fuel assembly under test is abnormal.

[0006] In the above scheme, by automatically acquiring the load measurement value of the fuel assembly under test and the corresponding alarm value range of the fuel assembly under test, and combining the load measurement value of the fuel assembly under test and the alarm value range, it is determined whether there is any abnormality in the transfer status of the fuel assembly under test, and an alarm is triggered in time when an abnormality occurs. This makes the automation and standardization of the monitoring of the transfer status of the fuel assembly higher, and also enables the operator to obtain the alarm signal at the first time, avoiding damage to the fuel assembly under test or reducing the degree of damage to the fuel assembly under test, and ensuring the transfer safety of the fuel assembly under test.

[0009] In one specific embodiment of this application, before obtaining the alarm value range corresponding to the fuel assembly under test, the method further includes: obtaining the operating mode. The operating mode includes a normal mode and a superimposed mode. The normal mode is used to determine whether the load measurement value of the fuel assembly under test exceeds the limit.

Obtaining the alarm value range corresponding to the fuel assembly under test includes: if the operating mode is the normal mode, obtaining the alarm value range corresponding to the fuel assembly under test in the normal mode; if the operating mode is the superimposed mode, obtaining the alarm value range corresponding to the fuel assembly under test in the superimposed mode.

[0010] In one specific embodiment of this application, the method further includes: obtaining the alert value range corresponding to the fuel assembly under test; determining whether the transfer state of the fuel assembly under test is in a state awaiting alert by combining the load measurement value of the fuel assembly under test and the alert value range; and issuing an alert signal if the transfer state of the fuel assembly under test is in a state awaiting alert.

The device for monitoring the transfer status of the fuel assembly is connected to the pressure sensor and is used to acquire the load measurement value of the fuel assembly under test from the pressure sensor. The wireless communication module is connected to the device and is used to wirelessly transmit signals generated by the device. These signals include alarm signals. The power supply module is electrically connected to the pressure sensor, the device, and the wireless communication module. The power supply module provides electrical power to the pressure sensor, the device, and the wireless communication module.

[0025] It should be noted that the device 10 for monitoring the transfer status of the fuel assembly can be an electronic device. The number of processors 11 can be one or more. The processor 11 can be a digital signal processor (DSP), a microcontroller, or a microprocessor, thereby ensuring the timeliness of the transfer status monitoring.

[0026] The application programs stored in memory 12 may include one or more modules, each corresponding to a set of instructions.

Whether these functions are implemented in hardware or software depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.

[0030] If the aforementioned functions are implemented as software functional units and sold or used as independent products, they can be stored in a computer-readable storage medium.

[0031] Figure 2 The diagram shown is a structural schematic of a wireless crane scale according to an embodiment of this application. The wireless crane scale 100 includes a pressure sensor 20, a wireless communication module 30, a power supply module 40, and... Figure 1The illustrated embodiment includes a device 10 for monitoring the transfer status of fuel assemblies. A pressure sensor 20 measures the fuel assembly under test to obtain its load measurement value. The device 10 for monitoring the transfer status of fuel assemblies is connected to the pressure sensor 20 and is used to obtain the load measurement value of the fuel assembly under test from the pressure sensor 20. A wireless communication module 30 is connected to the device 10 and is used to wirelessly transmit signals generated by the device 10. The signals include alarm signals. A power supply module 40 is electrically connected to the pressure sensor 20, the device 10, and the wireless communication module 30. The power supply module 40 is used to provide power to the pressure sensor 20, the device 10, and the wireless communication module 30. In this way, the device 10 in the wireless crane scale 100 completes the execution of the fuel assembly transfer status monitoring method in this embodiment and the storage of data such as load measurement values ​​and alarm value ranges during the execution process, instead of uniformly transmitting them to remote devices such as remote operation terminals for processing. This reduces data transmission links, and the wireless crane scale 100 can quickly read data such as load measurement values ​​and alarm value ranges locally, ensuring the timeliness of alarm signal issuance.

[0032] It should be noted that, in addition to alarm signals, the signals may also include reminder signals, etc. The power supply module 40 can be a lithium battery with rechargeable power supply function, so as to continuously provide power to devices such as pressure sensor 20, equipment and wireless communication module 30 during the battery life.

[0033] Figure 3 The diagram shown is a structural schematic of a wireless hook scale provided in another embodiment of this application. Figure 3 The embodiment shown is Figure 2 A variation of the illustrated embodiment. For example... Figure 3 As shown, with Figure 2The difference in the illustrated embodiment is that the wireless crane scale 100 further includes at least one of a display screen 50, a button unit 60, and an indicator light 70. The display screen 50 is electrically connected to the power supply module 40 and displays at least one of the following: the load measurement value of the fuel assembly under test, the transfer status of the fuel assembly under test, and the power level of the power supply module 40. The button unit 60 is electrically connected to the power supply module 40 and includes a power switch 61 and a zeroing button 62. The power switch 61 controls the start and stop of the wireless crane scale 100. The zeroing button 62 calibrates the wireless crane scale 100. The indicator light 70 is electrically connected to the power supply module 40 and indicates at least one of the power level of the power supply module 40 and the transfer status of the fuel assembly under test. Thus, by adding the display screen 50, at least one of the load measurement value of the fuel assembly under test, the transfer status of the fuel assembly under test, and the power level of the power supply module 40 can be displayed on the display screen 50 in real time, facilitating visual reading and calibration of the wireless crane scale 100 by the operator. In addition, by adding a button unit 60, the wireless crane scale 100 can be started and stopped using the switch button 61 in the button unit 60, and the wireless crane scale 100 can be calibrated using the zeroing button 62 in the button unit 60. By adding an indicator light 70, the power supply module 40 and the transfer status of the fuel component under test can be indicated, and the operator can know the power supply module 40 and the transfer status of the fuel component under test through multiple means such as the display screen 50 and the indicator light 70.

[0034] It should be noted that the wireless crane scale 100 can be a wireless electronic scale used in the transfer process of fuel components under test. The display screen 50 can be an electronic display screen or a touch screen. Any one or more of the switch button 61 and the zeroing button 62 can be a circular push-button switch or a rocker switch, etc. The indicator light 70 can be a color indicator light; for example, a red indicator light indicates low power, and a green indicator light indicates normal power.

[0035] Figure 4The diagram shows a structural schematic of a fuel assembly transfer status monitoring system according to an embodiment of this application. The fuel assembly transfer status monitoring system 200 includes the wireless crane scale 100 described in the above embodiment of this application, at least one remote operation terminal 210, and at least one wireless audible and visual alarm light 220. The at least one remote operation terminal 210 is wirelessly connected to the wireless communication module 30 in the wireless crane scale 100. The at least one remote operation terminal 210 is used to receive and display alarm signals emitted by the wireless crane scale 100, and to send system parameters to the wireless crane scale 100. The system parameters include alarm value ranges. The at least one wireless audible and visual alarm light 220 is wirelessly connected to the wireless communication module 30, and is used to receive alarm signals emitted by the wireless crane scale 100, and to issue an alarm to the operator in audible and visual form upon receiving the alarm signal. Thus, by wirelessly connecting the wireless crane scale 100 to at least one remote operation terminal 210 and at least one wireless audible and visual alarm light 220, there is no risk of cable entanglement between any two of the wireless crane scale 100, at least one remote operation terminal 210, and at least one wireless audible and visual alarm light 220 during the transfer of the fuel assembly under test. This allows for flexible on-site movement and deployment, significantly improving operational efficiency. Furthermore, the wireless crane scale 100 supports one-to-many simultaneous communication, enabling flexible configuration of any one of the at least one remote operation terminal 210 and at least one wireless audible and visual alarm light 220, and also making the system 200 flexible to expand and easy to maintain. In addition, by setting the wireless audible and visual alarm light 220 to receive alarm signals from the wireless crane scale 100 via the wireless communication module 30 of the wireless crane scale 100, the operator responsible for transferring the fuel assembly under test can receive an anomaly alarm immediately, preventing damage to the fuel assembly under test or reducing the degree of damage. Furthermore, the system 200 in this embodiment can automatically complete the data acquisition, transfer status judgment, and abnormal alarm of the transfer process of the fuel assembly under test. Utilizing key technologies such as multi-terminal wireless communication, remote human-machine interaction, and multi-state judgment modes, it completes the fuel assembly transfer status monitoring from "remote operation terminal mode selection -> wireless hook scale data acquisition and status judgment -> mobile wireless audible and visual alarm light alarm -> remote operation terminal saving and display". It is applicable to all fuel assemblies and the entire operation process, and has the machine "brain" capabilities for reading, judgment, and alarming. It effectively ensures the safe and efficient operation of fuel assembly transfer, reduces the burden of manual operation and the risk of human error, while improving operation efficiency and reducing production costs.

[0036] It should be noted that before the device 10 in the wireless crane scale 100 executes the fuel assembly transfer status monitoring method in this application embodiment, each device in the fuel assembly transfer status monitoring system 200 can be powered on for self-test and wireless communication connection. The operator can move at least one remote operation terminal 210 to the working position, and at least one wireless audible and visual alarm light 220 can be placed near the operator receiving the alarm signal, thereby further ensuring that the operator obtains the alarm signal as soon as possible.

[0037] The remote operation terminal 210 can be equipped with supporting system software for human-machine interaction, and can also have functions such as system parameter setting, data saving, data query, curve plotting, status display, alarm output, and data export. Operators can pre-set system parameters on the remote operation terminal 210. These parameters include alarm value ranges, reminder value ranges, power alarm thresholds, and data sampling frequencies. After setting the system parameters, the remote operation terminal 210 can remotely send some or all of the system parameters to the wireless transmission hook scale 100. The wireless transmission hook scale 100 can automatically receive, save, and apply the system parameters. The remote operation terminal 210 can execute corresponding responses after receiving alarm signals from the wireless hook scale 100. For example, upon receiving an alarm signal, the software interface of the remote operation terminal 210 can respond with indicator light icons or background color blocks, or with a high-frequency flashing red alarm. The remote operation terminal 210 can also execute corresponding responses after receiving reminder signals from the wireless hook scale 100. For example, upon receiving a reminder signal, the software interface of the remote operation terminal 210 can display a high-frequency flashing yellow reminder.

[0038] The alarm sound volume and flashing frequency of the wireless audible and visual alarm light 220 can be set according to the working environment. Upon receiving an alarm signal from the wireless crane scale 100, the wireless audible and visual alarm light 220 can respond accordingly, emitting a colored flashing sound and light at a set volume and frequency. For example, upon receiving an alarm signal, the wireless audible and visual alarm light 220 emits a red flashing sound and light alarm at a set volume and frequency. Upon receiving an alert signal from the wireless crane scale 100, the wireless audible and visual alarm light 220 can also respond accordingly, emitting a colored flashing sound and light at a set volume and frequency. For example, upon receiving an alert signal, the wireless audible and visual alarm light 220 emits a yellow flashing sound and light alert at a set volume and frequency. In some embodiments, the sound corresponding to the alarm signal can be higher than the sound corresponding to the alert signal, and the frequency of the alarm signal can be higher than the frequency of the alert signal.

[0039] The wireless communication module 30 can use wireless data transmission, WIFI (Wireless Fidelity) or Bluetooth and other wireless communication technologies to support one-to-many simultaneous communication, so that the wireless hook scale 100 can communicate wirelessly with at least one remote operation terminal 210 and at least one wireless sound and light alarm light 220 respectively, thereby realizing the wireless transmission of measurement data, human-machine interaction data, alarm signals and reminder signals.

[0040] In the several embodiments provided in this application, it should be understood that the disclosed devices and systems can be implemented in other ways. For example, the device embodiments described above are merely illustrative. For instance, the division of modules is only a logical functional division, and in actual implementation, there may be other division methods. For example, multiple modules may be combined or integrated into another system, or some features may be ignored or not executed.

[0041] Those skilled in the art will understand that, for the sake of convenience and brevity, the specific working process and technical effects of the device 10, the wireless hook scale 100, and the system 200 described above can be further referred to the description in the following method embodiments, and will not be repeated here.

[0042] Figure 5 The diagram shown is a flowchart illustrating a method for monitoring the transfer status of a fuel assembly according to an embodiment of this application. Figures 1 to 4 Any of the embodiments can be used for the application scenario corresponding to this method. The execution subject of this method can be a processor or a controller, etc. The following description uses a processor as the execution subject. The method includes the following steps.

[0043] S200: Acquire the load measurement value of the fuel assembly under test.

[0044] Specifically, the pressure sensor 20 can measure the actual load of the fuel assembly under test in real time or at preset intervals during the transfer process, and convert the actual load into an electrical signal, which can be used as the load measurement value. The processor 11 can obtain the load measurement value of the fuel assembly under test from the pressure sensor 20 of the wireless crane scale 100 in real time or at preset intervals.

[0045] S400: Obtain the alarm value range corresponding to the fuel assembly under test.

[0046] Specifically, the operator can set the alarm value range corresponding to the fuel component under test on the remote operation terminal 210. The wireless crane scale 100 can receive the alarm value range sent by the remote operation terminal 210 through the wireless communication module 30 and save the alarm value range in the memory 12. The processor 11 can retrieve the alarm value range corresponding to the fuel component under test from the memory 12 according to actual needs.

[0047] S600: Determine whether the transfer status of the fuel assembly under test is abnormal by combining the load measurement value and alarm value range of the fuel assembly under test.

[0048] S800: If the transfer status of the fuel assembly under test is abnormal, an alarm signal will be sent.

[0049] Specifically, if the transfer status of the fuel component under test is abnormal, the processor 11 can immediately send an alarm signal to the remote operation terminal 210 and the wireless audible and visual alarm light 220.

[0050] According to the technical solution provided in this application, by automatically acquiring the load measurement value of the fuel assembly under test and the corresponding alarm value range of the fuel assembly under test, and combining the load measurement value and alarm value range of the fuel assembly under test, it is determined whether the transfer status of the fuel assembly under test is abnormal. This makes the method of monitoring the transfer status of fuel assemblies more intelligent and standardized, reduces the probability of errors caused by human factors, and improves the real-time performance and accuracy of monitoring the transfer status of the fuel assembly under test. In addition, by sending an alarm signal when the transfer status of the fuel assembly under test is abnormal, the operator can obtain the alarm signal at the first time, avoiding damage to the fuel assembly under test or reducing the degree of damage to the fuel assembly under test, and also ensuring the transfer safety of the fuel assembly under test.

[0051] Figure 6 The diagram shown is a flowchart illustrating a method for monitoring the transfer status of fuel assemblies according to another embodiment of this application. Figure 6 As shown Figure 5 A variation of the illustrated embodiment. For example... Figure 6 As shown, with Figure 5 The difference in the illustrated embodiment is that the method further includes S300, and S410 is a specific implementation of S400.

[0052] S300: Obtain operating mode. Operating modes include normal mode and overlay mode. Normal mode is used to determine whether the load measurement value of the fuel assembly under test exceeds the limit. Overlay mode is used to determine whether the load change corresponding to the load measurement value of the fuel assembly under test exceeds the limit.

[0053] It should be noted that operators can remotely switch between multiple modes on the remote operation terminal and remotely modify data such as alarm value ranges and alert value ranges. Operators can pre-configure alarm schemes based on accumulated data, operating modes, and fuel component types. An alarm scheme can consist of a scheme name, alarm value range, and alert value range. The scheme name can include normal mode and overlay mode.

[0054] S410: If the operating mode is normal mode, obtain the alarm value range corresponding to the fuel component under test in normal mode.

[0055] In some embodiments, if the scheme name is Normal Mode, the processor 11 can retrieve the alarm value range corresponding to the fuel component under test in Normal Mode from the memory 12 according to the scheme name.

[0056] S420: If the working mode is superimposed mode, then obtain the alarm value range corresponding to the fuel component under test in superimposed mode.

[0057] In some embodiments, if the scheme name is superimposed mode, the processor 11 can retrieve the alarm value range corresponding to the fuel component under test in superimposed mode from the memory 12 according to the scheme name.

[0058] According to the technical solution provided in the embodiments of this application, by setting the working mode to include a normal mode and an overlay mode, the method for monitoring the transfer status of fuel assemblies can adapt to the switching of multiple working modes, and the method for monitoring the transfer status of fuel assemblies can be applied to the monitoring needs of the transfer status of fuel assemblies in different nuclear power units. Furthermore, the method for monitoring the transfer status of fuel assemblies can be extended to the monitoring of the transfer status of other key components.

[0059] In at least one embodiment of this application, S610 to S630 are specific implementations of step S600.

[0060] S610: Determine whether the load measurement value of the fuel assembly under test is within the alarm value range.

[0061] In some embodiments, if the operating mode includes a normal mode and a superimposed mode, then when the operating mode is normal mode, the processor 11 can determine whether the load measurement value of the fuel assembly under test is within the alarm value range.

[0062] For example, the alarm value range can be [LAmin, LAmax], where LAmin is the lower alarm threshold and LAmax is the upper alarm threshold. The processor 11 can compare the load measurement value L of the fuel assembly under test with LAmin and LAmax in real time to determine whether the load measurement value L of the fuel assembly under test is within [LAmin, LAmax].

[0063] S620: If the load measurement value of the fuel assembly under test is within the alarm value range, then the transfer status of the fuel assembly under test is determined to be normal.

[0064] For example, if the load measurement value L of the fuel assembly under test is within [LAmin, LAmax], then the processor 11 can determine that the transfer state of the fuel assembly under test is normal.

[0065] It should be noted that step S200 can be executed after step S620.

[0066] S630: If the load measurement value of the fuel assembly under test exceeds the alarm value range, it is determined that the transfer status of the fuel assembly under test is abnormal.

[0067] For example, if the load measurement value L of the fuel assembly under test exceeds [LAmin, LAmax], that is, the load measurement value L of the fuel assembly under test is less than LAmin or greater than LAmax, then the processor 11 can determine that the transfer state of the fuel assembly under test is abnormal.

[0068] In this embodiment of the application, the transfer status of the fuel assembly under test is determined to be abnormal by whether the load measurement value of the fuel assembly under test is within the alarm value range. This provides a way to determine whether the transfer status of the fuel assembly under test is abnormal, and the method requires less computation, which is beneficial to improving monitoring efficiency.

[0069] In at least one embodiment of this application, S640 to S680 are another specific implementation of step S600.

[0070] S640: Obtain the load reference value of the fuel assembly under test.

[0071] In some embodiments, if the operating modes include a normal mode and a superimposed mode, then when the operating mode is superimposed mode, the processor 11 can obtain the load reference value of the fuel assembly under test. The load reference value can be a preset value or the load measurement value at the time when the superimposed mode is active.

[0072] S650: Determine the load change of the fuel assembly under test based on the measured load value and the load reference value.

[0073] For example, the load measurement value can be L, and the load reference value can be L0. The processor 11 can calculate the load change ΔL = L - L0 of the fuel assembly under test based on the load measurement value L and the load reference value L0 of the fuel assembly under test.

[0074] S660: Determine whether the load change of the fuel assembly under test is within the alarm value range.

[0075] For example, the alarm value range can be [ΔLAmin, ΔLAmax], where ΔLAmin is the lower alarm threshold and ΔLAmax is the upper alarm threshold. The processor 11 can compare the load change ΔL of the fuel assembly under test with ΔLAmin and ΔLAmax in real time to determine whether the load change ΔL of the fuel assembly under test is within [ΔLAmin, ΔLAmax].

[0076] S670: If the load change of the fuel assembly under test is within the alarm value range, then the transfer status of the fuel assembly under test is determined to be normal.

[0077] For example, if the load change ΔL of the fuel assembly under test is within [ΔLAmin, ΔLAmax], then the processor 11 can determine that the transfer state of the fuel assembly under test is normal.

[0078] It should be noted that step S200 can be executed after step S670.

[0079] S680: If the load change of the fuel assembly under test exceeds the alarm value range, it is determined that the transfer status of the fuel assembly under test is abnormal.

[0080] For example, if the load change ΔL of the fuel assembly under test exceeds [ΔLAmin, ΔLAmax], that is, the load change ΔL of the fuel assembly under test is less than ΔLAmin or greater than ΔLAmax, then the processor 11 can determine that the transfer state of the fuel assembly under test is abnormal.

[0081] In this embodiment of the application, by determining whether the transfer status of the fuel assembly under test is in an abnormal state based on whether the load change of the fuel assembly under test is within the alarm value range, another way to determine whether the transfer status of the fuel assembly under test is in an abnormal state is provided. The operator can select an appropriate working mode based on actual conditions such as the type of fuel assembly under test or the transfer method of the fuel assembly under test to determine whether the transfer status of the fuel assembly under test is in an abnormal state.

[0082] Figure 7 The diagram shown is a flowchart illustrating a method for monitoring the transfer status of a fuel assembly according to another embodiment of this application. Figure 7 The embodiment shown is Figure 5 A variation of the illustrated embodiment, and Figure 5 The difference in the illustrated embodiment is that the method further includes S500, S700 and S900.

[0083] S500: Obtain the range of alert values ​​corresponding to the fuel component under test.

[0084] Specifically, the operator can set the alert value range corresponding to the fuel component under test on the remote operation terminal 210. The wireless crane scale 100 can receive the alert value range sent by the remote operation terminal 210 through the wireless communication module 30 and save the alert value range in the memory 12. The processor 11 can retrieve the alert value range corresponding to the fuel component under test from the memory 12 according to actual needs.

[0085] For example, the alarm value range can be [LWmin, LWmax], where LWmin is the lower alarm threshold and LWmax is the upper alarm threshold.

[0086] S700: Determine whether the transfer status of the fuel assembly under test is in a state of pending alert by combining the load measurement value of the fuel assembly under test and the alert value range.

[0087] In some embodiments, if the working mode is normal mode, step S700 may include: determining whether the load measurement value of the fuel assembly under test is within the warning value range, for example, the warning value range is [LWmin, LWmax]. The processor 11 can compare the load measurement value L of the fuel assembly under test with LWmin and LWmax respectively in real time to determine whether the load measurement value L of the fuel assembly under test is within [LWmin, LWmax]. If the load measurement value of the fuel assembly under test exceeds the warning value range, it is determined that the transfer state of the fuel assembly under test is in the warning state. In other embodiments, if the working mode is superimposed mode, step S700 may include: obtaining the load reference value of the fuel assembly under test; determining the load change of the fuel assembly under test based on the load measurement value and the load reference value; determining whether the load change of the fuel assembly under test is within the warning value range, for example, the warning value range is [ΔLWmin, ΔLWmax]. The processor 11 can compare the load change ΔL of the fuel assembly under test with ΔLWmin and ΔLWmax in real time to determine whether the load change ΔL of the fuel assembly under test is within [ΔLWmin, ΔLWmax]; if the load change of the fuel assembly under test exceeds the warning value range, it is determined that the transfer state of the fuel assembly under test is in the warning state.

[0088] It should be noted that step S700 may precede step S400 or step S600, etc. This embodiment does not specifically limit the order of step S700 in the method. For example, step S700 may precede step S400; if the transfer status of the fuel assembly under test is not in the state awaiting notification, then step S400 is executed. Alternatively, step S500 may be performed synchronously with step S400, and step S700 may follow step S600; for example, if the transfer status of the fuel assembly under test is not in the state awaiting notification, then step S600 is executed.

[0089] S900: If the transfer status of the fuel assembly under test is in a state of pending reminder, a reminder signal will be issued.

[0090] Specifically, if the transfer status of the fuel component under test is in a state of waiting for reminder, the processor 11 can immediately send a reminder signal to the remote operation terminal 210 and the wireless audible and visual alarm light 220.

[0091] In this embodiment, the transfer status of the fuel assembly under test is determined by combining the load measurement value and the warning value range. When the transfer status of the fuel assembly under test is in the warning state, a warning signal is issued. This provides an advance warning that the transfer status of the fuel assembly under test is about to become abnormal before an alarm is triggered. This allows operators to repair the fuel assembly under test earlier and prevents further damage to the fuel assembly under test.

All technical features described in this application can be freely combined or combined in any way, unless they contradict each other.
