Description

Technical Field

[0001] The present application belongs to the technical field of fuel assembly transportation, and specifically relates to a method, device and system for monitoring the transportation status of a fuel assembly, and a wireless hook scale. Background Art

[0002] Fuel assemblies are the source of energy for nuclear power plants to generate electricity. They are not only expensive but also closely related to safety. During the transportation of fuel assemblies, they must be monitored throughout the entire process to ensure that they are not damaged. Due to the limitations of the on-site environment, operators cannot monitor closely next to the fuel assemblies, especially during the process of transporting new fuel assemblies from packaging boxes to the storage cells in the spent fuel pool. Generally, a crane is used to suspend a hook scale and then suspend the fuel assembly to indirectly monitor the status. The operator determines the normal load fluctuation range based on the type of fuel assembly (different types of related components are plugged in), and then combines the real-time measurement value of the hook scale to determine whether it is abnormal. Once the new fuel assembly is scratched or hooked with other equipment, the measurement value of the hook scale changes beyond the normal fluctuation range, and an abnormal alarm is manually issued to the crane operator, and the transportation is immediately stopped until the abnormality is eliminated, avoiding damage to the fuel assembly or reducing the degree of damage.

[0003] However, repeated transfers on site are likely to fail to detect abnormalities in a timely manner. There are many types of fuel assemblies, and the normal fluctuation range of loads is also wide. Manual memory or table lookup is prone to errors. In addition, the length of the fuel assembly is about 4m, and the position of the hook scale is not convenient for reading. Manual visual reading is prone to errors or delays. More importantly, there is a certain response delay when manually issuing abnormal alarms, and the driving operator cannot obtain the alarm information in the first time, so it is impossible to avoid the expansion of the damage to the fuel assembly. Summary of the invention

[0004] In view of this, the present application provides a method, device and system for monitoring the transfer status of fuel assemblies, and a wireless hook scale, which automatically monitors the transfer status of fuel assemblies and promptly issues an alarm when the operating status of the fuel assemblies is abnormal, so that the transfer operators can obtain abnormal alarms in the first place, avoid damage to the fuel assemblies or reduce the degree of damage, and reduce the burden of manual work and the risk of human error.

[0033] Figure 3 Shown is a schematic structural diagram of a wireless hook scale provided in another embodiment of the present application. Figure 3 The embodiment shown is Figure 2 A variation of the embodiment shown. Figure 3 As shown, Figure 2The difference of the illustrated embodiment is that the wireless hook 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 the display screen 50 is used to display at least one of the load measurement value of the fuel assembly to be tested, the transportation status of the fuel assembly to be tested and the power supply power of the power supply module 40; the button unit 60 is electrically connected to the power supply module 40, and the button unit 60 includes a switch button 61 and a reset button 62.

The indicator light is electrically connected to the power supply module 40, and the indicator light 70 is used to indicate at least one of the power supply power of the power supply module 40 and the transportation status of the fuel assembly to be tested. In this way, by adding the display screen 50, at least one of the load measurement value of the fuel assembly to be tested, the transportation status of the fuel assembly to be tested and the power supply power of the power supply module 40 can be displayed on the display screen 50 in real time, so as to facilitate the operator to visually read and calibrate the wireless hook scale 100. In addition, by adding a button unit 60, the switch button 61 in the button unit 60 can be used to control the start and stop of the wireless hook scale 100, and the reset button 62 in the button unit 60 can be used to calibrate the wireless hook scale 100. By adding an indicator light 70, the indicator light 70 can be used to indicate the power supply of the power supply module 40 and the transportation status of the fuel assembly to be tested, so that the operator can know the power supply of the power supply module 40 and the transportation status of the fuel assembly to be tested through various methods such as the display screen 50 and the indicator light 70.

[0034] It should be noted that the wireless hook scale 100 can be a wireless electronic scale used in the transportation process of the fuel assembly to be tested.

[0035] Figure 4The structure diagram of a system for monitoring the transportation status of a fuel assembly provided by an embodiment of the present application is shown. The system 200 for monitoring the transportation status of a fuel assembly includes the wireless hook scale 100 in the above embodiment of the present application, at least one remote operation terminal 210 and at least one wireless sound and light alarm light 220. At least one remote operation terminal 210 is wirelessly connected to the wireless communication module 30 in the wireless hook scale 100. At least one remote operation terminal 210 is used to receive and display the alarm signal issued by the wireless hook scale 100, and send system parameters to the wireless hook scale 100. The system parameters include an alarm value range. At least one wireless sound and light alarm light 220 is wirelessly connected to the wireless communication module 30, and at least one wireless sound and light alarm light 220 is used to receive the alarm signal issued by the wireless hook scale 100, and send an alarm to the operator in the form of sound and light after receiving the alarm signal. In this way, by setting the wireless hook scale 100 to be wirelessly connected with at least one remote operation terminal 210 and at least one wireless sound and light alarm lamp 220 respectively, there is no risk of cable entanglement between any two of the wireless hook scale 100, at least one remote operation terminal 210 and at least one wireless sound and light alarm lamp 220 during the transportation of the fuel assembly to be tested, and the on-site movement or arrangement is flexible, which greatly improves the working efficiency. In addition, the wireless hook scale 100 is used as the core to support one-to-many simultaneous communication, so that the configuration of any one of the at least one remote operation terminal 210 and at least one wireless sound and light alarm lamp 220 is flexible, and the system 200 is also flexible to expand and easy to maintain. In addition, by setting the wireless sound and light alarm lamp 220 to receive the alarm signal sent by the wireless hook scale 100 through the wireless communication module 30 of the wireless hook scale 100, the operator responsible for the transportation of the fuel assembly to be tested can obtain an abnormal alarm in the first time, avoiding damage to the fuel assembly to be tested or reducing the degree of damage to the fuel assembly to be tested. In addition, the system 200 in the embodiment of the present application can automatically complete the data collection, transportation status judgment and abnormal alarm of the transportation process of the fuel assembly to be tested, and utilize key technologies such as multi-terminal wireless communication, remote human-computer interaction and multi-state judgment mode to complete the fuel assembly transportation status monitoring of "remote operation terminal mode selection->wireless hook scale data collection and status judgment->mobile wireless sound and light alarm light alarm->remote operation terminal storage and display". It is suitable for all fuel assemblies and the entire operation process, and has the ability of the machine's "brain" to read, judge and alarm, which effectively ensures the safe and efficient operation of fuel assembly transportation, reduces the burden of manual work and the risk of human errors, and at the same time improves operating efficiency and reduces production costs.

[0036] It should be noted that before the device 10 in the wireless hook scale 100 executes the method for monitoring the transfer status of fuel assemblies in the embodiment of the present application, each device in the system 200 for monitoring the transfer status of fuel assemblies can be powered on for self-test and wireless communication connection, and the operator can move at least one remote operation terminal 210 to the working position respectively, and can arrange at least one wireless sound and light alarm light 220 near the operator who receives the alarm signal, thereby further ensuring that the operator obtains the alarm signal as soon as possible.

[0037] The remote operation terminal 210 may be installed with supporting system software for human-computer interaction, and may also have functions such as system parameter setting, data storage, data query, curve drawing, status display, alarm output and data export. The operator can set the system parameters in advance on the remote operation terminal 210. In addition to the alarm value range, the system parameters may also include the reminder value range, the power alarm threshold and the data sampling frequency. After the system parameters are set, the remote operation terminal 210 can remotely send part or all of the system parameters to the wireless transmission hook scale 100, and the wireless transmission hook scale 100 can automatically receive the system parameters and save and take effect. The remote operation terminal 210 can perform a corresponding response after receiving the alarm signal sent by the wireless hook scale 100. For example, after receiving the alarm signal, the software interface of the remote operation terminal 210 can respond with an indicator light icon or a background color block, or it can alarm with a red high-frequency flashing. The remote operation terminal 210 can perform a corresponding response after receiving the reminder signal sent by the wireless hook scale 100. For example, after receiving the reminder signal, the software interface of the remote operation terminal 210 can remind with a yellow high-frequency flashing.

[0038] The alarm sound volume and alarm light flashing frequency corresponding to the wireless sound and light alarm light 220 can be set according to the working environment. The wireless sound and light alarm light 220 can perform a corresponding response after receiving the alarm signal sent by the wireless hook scale 100, and emit color flashing sound and light at a set volume and frequency. For example, after receiving the alarm signal, the wireless sound and light alarm light 220 emits a red flashing sound and light alarm at a set volume and frequency. The wireless sound and light alarm light 220 can perform a corresponding response after receiving the reminder signal sent by the wireless hook scale 100, and emit color flashing sound and light at a set volume and frequency. For example, after receiving the reminder signal, the wireless sound and light alarm light 220 emits a yellow flashing sound and light reminder 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 reminder signal, and the frequency corresponding to the alarm signal can be higher than the frequency corresponding to the reminder 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 realize wireless communication with at least one remote operation terminal 210 and at least one wireless sound and light alarm light 220 respectively, thereby realizing wireless transmission of measurement data, human-computer 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 only schematic, for example, the division of the modules is only a logical function division, and there may be other division methods in actual implementation, such as multiple modules can be combined or integrated into another system, or some features can be ignored or not executed.

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

[0042] Figure 5 Shown is a flow chart of a method for monitoring the transport status of a fuel assembly provided in one embodiment of the present application. Figures 1 to 4 Any of the embodiments may be an application scenario corresponding to the method. The execution subject of the method may be a processor or a controller, etc. The following description is made by taking the processor as the execution subject as an example. The method includes the following steps.

[0043] S200: Obtaining a load measurement value of the fuel assembly to be tested.

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

[0045] S400: Obtain the alarm value range corresponding to the fuel assembly to be tested.

[0046] Specifically, the operator can set the alarm value range corresponding to the fuel assembly to be tested at the remote operation terminal 210, and the wireless hook 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 obtain the alarm value range corresponding to the fuel assembly to be tested from the memory 12 according to actual needs.

[0047] S600: Determine whether the transport state of the fuel assembly to be tested is abnormal based on the load measurement value and the alarm value range of the fuel assembly to be tested.

[0048] S800: If the transport status of the fuel assembly to be tested is in an abnormal state, an alarm signal is sent.

[0049] Specifically, if the transport status of the fuel assembly to be tested is in an abnormal state, the processor 11 can immediately send an alarm signal to the remote operation terminal 210 and the wireless sound and light alarm lamp 220 .

[0050] According to the technical solution provided in the embodiment of the present application, by automatically obtaining the load measurement value of the fuel assembly to be tested and the alarm value range corresponding to the fuel assembly to be tested, and combining the load measurement value of the fuel assembly to be tested and the alarm value range to determine whether the transportation state of the fuel assembly to be tested is abnormal, the method of monitoring the transportation state of the fuel assembly is made more intelligent and standardized, the probability of errors caused by human factors is reduced, and the real-time and accuracy of the transportation state monitoring of the fuel assembly to be tested is improved. In addition, by sending an alarm signal when the transportation state of the fuel assembly to be tested is in an abnormal state, the operator can obtain the alarm signal in the first time, avoiding damage to the fuel assembly to be tested or reducing the degree of damage to the fuel assembly to be tested, and ensuring the transportation safety of the fuel assembly to be tested.

[0051] Figure 6 Shown is a flow chart of a method for monitoring the transport status of a fuel assembly provided in another embodiment of the present application. Figure 6 Shown Figure 5 A variation of the embodiment shown. Figure 6 As shown, Figure 5 The difference between the illustrated embodiment is that the method further includes S300, and S410 is a specific implementation of S400.

[0052] S300: Obtaining a working mode. The working mode includes a normal mode and an overlay mode. The normal mode is used to determine whether the load measurement value of the fuel assembly to be tested exceeds the limit. The overlay mode is used to determine whether the load change corresponding to the load measurement value of the fuel assembly to be tested exceeds the limit.

[0053] It should be noted that the operator can remotely switch between multiple modes in the remote operation terminal, and can remotely modify data such as alarm value range and reminder value range. The operator can configure the alarm scheme in advance according to the data accumulation, working mode, type of fuel assembly, etc. The alarm scheme can be composed of scheme name, alarm value range and reminder value range. The scheme name can include normal mode and superposition mode.

[0054] S410: If the working mode is the normal mode, then obtain the alarm value range corresponding to the fuel assembly to be tested in the normal mode.

[0055] In some embodiments, if the scheme name is the normal mode, the processor 11 may retrieve the alarm value range corresponding to the fuel assembly to be tested in the normal mode from the memory 12 according to the scheme name.

[0056] S420: If the working mode is the overlay mode, then obtain the alarm value range corresponding to the fuel assembly to be tested in the overlay mode.

[0057] In some embodiments, if the scheme name is the overlay mode, the processor 11 may retrieve the alarm value range corresponding to the fuel assembly to be tested in the overlay mode from the memory 12 according to the scheme name.

[0058] According to the technical solution provided in the embodiment of the present application, by setting the working modes to include normal mode and 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 suitable for the monitoring needs of the transfer status of fuel assemblies in different current nuclear power units. The method for monitoring the transfer status of fuel assemblies can also be extended to the monitoring of the transfer status of other key components.

[0059] In at least one embodiment of the present application, S610 to S630 are a specific implementation of step S600.

[0060] S610: Determine whether the load measurement value of the fuel assembly to be tested is within the alarm value range.

[0061] In some embodiments, if the working mode includes a normal mode and an overlay mode, then when the working mode is the normal mode, the processor 11 may determine whether the load measurement value of the fuel assembly to be tested is within the alarm value range.

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

[0063] S620: If the load measurement value of the fuel assembly to be tested is within the alarm value range, it is determined that the transport state of the fuel assembly to be tested is in a normal state.

[0064] For example, if the load measurement value L of the fuel assembly to be tested is within [LAmin, LAmax], the processor 11 may determine that the transport state of the fuel assembly to be tested is in a normal state.

[0065] It should be noted that step S200 may be continued after step S620.

[0066] S630: If the load measurement value of the fuel assembly to be tested exceeds the alarm value range, it is determined that the transport state of the fuel assembly to be tested is in an abnormal state.

[0067] For example, if the load measurement value L of the fuel assembly to be tested exceeds [LAmin, LAmax], that is, the load measurement value L of the fuel assembly to be tested is less than LAmin or greater than LAmax, the processor 11 may determine that the transport state of the fuel assembly to be tested is in an abnormal state.

[0068] In an embodiment of the present application, whether the transport state of the fuel assembly to be tested is in an abnormal state is determined based on whether the load measurement value of the fuel assembly to be tested is within the alarm value range, thereby providing a method for determining whether the transport state of the fuel assembly to be tested is in an abnormal state, and this method has less calculation amount, which is conducive to improving monitoring efficiency.

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

[0070] S640: Obtain a load reference value of the fuel assembly to be tested.

[0071] In some embodiments, if the working mode includes a normal mode and an overlay mode, the processor 11 may obtain a load reference value of the fuel assembly to be tested when the working mode is the overlay mode. The load reference value may be a preset value or a load measurement value when the overlay mode takes effect.

[0072] S650: Determine the load variation of the fuel assembly to be tested according to the load measurement value and the load reference value of the fuel assembly to be tested.

[0073] For example, the load measurement value may be L, and the load reference value may be L0. The processor 11 may calculate the load change ΔL=L-L0 of the fuel assembly to be tested according to the load measurement value L and the load reference value L0 of the fuel assembly to be tested.

[0074] S660: Determine whether the load change of the fuel assembly to be tested is within the alarm value range.

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

[0076] S670: If the load variation of the fuel assembly to be tested is within the alarm value range, it is determined that the transport state of the fuel assembly to be tested is in a normal state.

[0077] For example, if the load variation ΔL of the fuel assembly to be tested is within [ΔLAmin, ΔLAmax], the processor 11 may determine that the transport state of the fuel assembly to be tested is in a normal state.

[0078] It should be noted that step S200 may be continued after step S670.

[0079] S680: If the load variation of the fuel assembly to be tested exceeds the alarm value range, it is determined that the transport state of the fuel assembly to be tested is in an abnormal state.

[0080] For example, if the load change ΔL of the fuel assembly to be tested exceeds [ΔLAmin, ΔLAmax], that is, the load change ΔL of the fuel assembly to be tested is less than ΔLAmin or greater than ΔLAmax, the processor 11 can determine that the transport state of the fuel assembly to be tested is in an abnormal state.

[0081] In an embodiment of the present application, by determining whether the transport state of the fuel assembly to be tested is in an abnormal state based on whether the load change of the fuel assembly to be tested is within the alarm value range, another way to determine whether the transport state of the fuel assembly to be tested is in an abnormal state is provided. The operator can select a suitable working mode according to actual conditions such as the type of fuel assembly to be tested or the transport method of the fuel assembly to be tested to determine whether the transport state of the fuel assembly to be tested is in an abnormal state.

[0082] Figure 7 Shown is a flow chart of a method for monitoring the transport status of a fuel assembly provided in yet another embodiment of the present application. Figure 7 The embodiment shown is Figure 5 A variation of the embodiment shown, with Figure 5 The difference of the illustrated embodiment is that the method further includes S500 , S700 , and S900 .

[0083] S500: Obtain the reminder value range corresponding to the fuel assembly to be tested.

[0084] Specifically, the operator can set the reminder value range corresponding to the fuel assembly to be tested at the remote operation terminal 210, and the wireless hook scale 100 can receive the reminder value range sent by the remote operation terminal 210 through the wireless communication module 30 and save the reminder value range in the memory 12. The processor 11 can obtain the reminder value range corresponding to the fuel assembly to be tested from the memory 12 according to actual needs.

[0085] For example, the reminder value range may 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 to be tested is in a waiting-for-reminder status in combination with the load measurement value and the reminder value range of the fuel assembly to be tested.

[0087] In some embodiments, if the working mode is the normal mode, step S700 may include: determining whether the load measurement value of the fuel assembly to be tested is within the reminder value range, for example, the reminder value range is [LWmin, LWmax], the processor 11 may compare the load measurement value L of the fuel assembly to be tested with LWmin and LWmax respectively in real time, so as to determine whether the load measurement value L of the fuel assembly to be tested is within [LWmin, LWmax]; if the load measurement value of the fuel assembly to be tested exceeds the reminder value range, it is determined that the transportation status of the fuel assembly to be tested is in the waiting for reminder state. In other embodiments, if the working mode is the overlay mode, step S700 may include: obtaining a load reference value of the fuel assembly to be tested; determining a load change of the fuel assembly to be tested according to the load measurement value and the load reference value of the fuel assembly to be tested; judging whether the load change of the fuel assembly to be tested is within a reminder value range, for example, the reminder value range is [ΔLWmin, ΔLWmax]. The processor 11 may compare the load change ΔL of the fuel assembly to be tested with ΔLWmin and ΔLWmax respectively in real time, so as to judge whether the load change ΔL of the fuel assembly to be tested is within [ΔLWmin, ΔLWmax]. If the load change of the fuel assembly to be tested exceeds the reminder value range, it is determined that the transport status of the fuel assembly to be tested is in a waiting for reminder state.

[0088] It should be noted that step S700 may be performed before step S400, or before step S600, etc., and the present embodiment of the application does not specifically limit the order of step S700 in the method. For example, step S700 may be performed before step S400, and if the transport status of the fuel assembly to be tested is not in the state to be reminded, step S400 is performed. For another example, step S500 may be performed simultaneously with step S400, and step S700 may be performed after step S600, and if the transport status of the fuel assembly to be tested is not in the state to be reminded, step S600 is performed.

[0089] S900: If the transfer status of the fuel assembly to be tested is in a waiting-for-reminder status, a reminder signal is issued.

[0090] Specifically, if the transport status of the fuel assembly to be tested is in a state to be reminded, the processor 11 may immediately send a reminder signal to the remote operation terminal 210 and the wireless sound and light alarm lamp 220 .

[0091] In an embodiment of the present application, by combining the load measurement value and the reminder value range of the fuel assembly to be tested, it is determined whether the transfer status of the fuel assembly to be tested is in the state to be reminded, and a reminder signal is issued when the transfer status of the fuel assembly to be tested is in the state to be reminded, thereby making an advance reminder of the impending abnormality in the transfer status of the fuel assembly to be tested before the alarm is issued, which is beneficial for the operator to repair the fuel assembly to be tested earlier and avoid further expansion of the damage to the fuel assembly to be tested.

[0092] It should be noted that the combination of the various technical features in the embodiments of the present application is not limited to the combination described in the embodiments of the present application or the combination described in the specific embodiments, and all technical features described in the present application can be freely combined or combined in any way unless there is a contradiction between them.
