[0036] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0037] It should be noted that the terms "comprising" or "may include" used in the various embodiments of this application indicate the presence of the claimed function, operation, or element, and do not limit the addition of one or more functions, operations, or elements. Furthermore, as used in the various embodiments of this application, the terms "comprising," "having," and their cognates are intended only to indicate a specific feature, number, step, operation, element, component, or combination of the foregoing, and should not be construed as primarily excluding the presence of one or more other features, numbers, steps, operations, elements, components, or combinations of the foregoing, or adding one or more combinations of the foregoing.

[0038] In this application embodiment, the existing technology for fault monitoring and handling of rod-controlled rod position systems lacks a method that integrates fault monitoring, analysis, location, and handling. How to promptly and effectively handle faults and eliminate them is a problem that urgently needs to be solved. This application embodiment proposes a method for fault monitoring and handling of rod-controlled rod position systems. This method is applied to a terminal, which includes a host computer, a CAN communication card, a switch, and communication cables. Data interaction between the power cabinet and the logic cabinet, and between the measurement cabinet and the processing cabinet, is achieved via the CAN communication card. Data interaction between the test cabinet and the logic cabinet, between the logic cabinet and the host computer, and between the processing cabinet and the host computer is achieved via the switch. The host computer connects to an intelligent data terminal unit. The host computer includes a memory, a processor, and a computer program stored in the memory and executable on the processor. When the processor executes the program, it implements the method for fault monitoring and handling of the rod-controlled rod position system. A device for fault monitoring and handling of the rod-controlled rod position system runs on the terminal. This device acquires information about the cabinets included in the rod-controlled rod position system. The system monitors and handles operational information, including logic cabinets, power cabinets, processing cabinets, measurement cabinets, and testing cabinets. It parses this operational information to obtain the operational status of the cabinets within the rod control and positioning system. When a cabinet within the rod control and positioning system is in a fault state, it extracts the fault information of the faulty cabinet based on the operational information, configures a fault handling plan for the cabinet based on the fault information, and pushes the fault handling plan to maintenance personnel. Upon receiving an instruction that the fault handling plan has been executed, it re-acquires the current operational information of the cabinet, parses the current operational information to obtain the current operational status of the cabinet, and determines whether the current operational status of the cabinet is faulty. If it is still faulty, it continues to configure other fault handling plans for the cabinet based on the current fault information until the cabinet is fault-free, thus completing the fault monitoring and handling of the rod control and positioning system. This system can guide maintenance personnel to conduct fault diagnosis in an orderly manner and quickly and accurately eliminate faults, further improving the safety performance of nuclear power plants.

[0039] It is understandable that, such as Figure 1 As shown, data exchange between multiple power supply cabinets and logic cabinets, and between multiple measurement cabinets and processing cabinets, is achieved via CAN communication cards. Data exchange between test cabinets and logic cabinets, between logic cabinets and the host computer, and between processing cabinets and the host computer is achieved via switches. The host computer is equipped with software for monitoring and handling faults in the rod control and positioning system, which is mainly implemented based on the LabVIEW software platform.

[0040] Please refer to Figure 2 , Figure 2 This diagram illustrates a flowchart of a method for fault monitoring and handling of a rod control rod position system provided in an embodiment of the present invention. Figure 2 As shown, the method includes:

[0041] S210, Obtain the operating information of the cabinets included in the rod control and positioning system, wherein the cabinets include logic cabinets, power cabinets, processing cabinets, measurement cabinets, and test cabinets.

[0042] Specifically, the reactor rod control and positioning system is one of the most important core pieces of equipment in a nuclear power plant. During startup, power conversion, and shutdown, automatic or manual operation of the control rods is required to achieve normal power regulation or shutdown. The reactor rod control and positioning system consists of two parts: the rod control system and the rod positioning system, comprised of equipment cabinets and functional devices within the cabinets. The rod control system includes a logic cabinet and a power supply cabinet, whose main function is to regulate reactor power through the lifting, holding, and lowering of the control rod bundles, and to complete the shutdown rod lowering action after the shutdown circuit breaker is opened. The rod positioning system includes a processing cabinet and a measurement cabinet, whose main function is to provide operators with information on the position of the control rods within the reactor core, indicating the current location of the control rods.

[0043] Therefore, in order to monitor and handle faults during the operation of the rod control and positioning system, this embodiment obtains the operation information of the cabinets included in the rod control and positioning system, and the cabinets include logic cabinets, power cabinets, processing cabinets, measurement cabinets and test cabinets.

[0044] It should be noted that the cabinet has fault detection capabilities. For example, if the 24V power module of the power cabinet loses power, the main control module of the power cabinet can generate corresponding sequence information to characterize the fault.

[0045] S220, parse the operation information to obtain the operating status of the cabinets included in the rod control and position system.

[0046] In this embodiment, by parsing the operational information obtained above, the operational status of the racks included in the rod control and rack position system can be obtained. It can be understood that the operational status includes normal status and fault status. Furthermore, since this embodiment uses a host computer to aggregate the operational information of the racks included in the rod control and rack position system, and the host computer is equipped with software for executing the rod control and rack position system fault monitoring and handling methods, a graphical interface can be presented on the host computer based on the operation of this software, such as... Figure 3As shown, the interface displays the operating status of the logic cabinet, power cabinet, processing cabinet, measurement cabinet, and test cabinet. The operating status is divided into three states: normal, non-emergency fault, and emergency fault. When the cabinet is in a normal state, the "Normal" indicator light is on (green), and the fault information bar is empty. When a cabinet malfunctions, it is divided into two fault types: "Non-emergency fault" and "Emergency fault." When the fault type is non-emergency, the "Non-emergency fault" indicator light is on (yellow), and the fault information bar displays: fault type (non-emergency fault), time of fault detection, fault location (cabinet number), fault cause, fault status (occurrence), and fault handling reminder. When the fault type is emergency, the "Emergency fault" indicator light is on (red), and the fault information bar displays: fault type (emergency fault), time of fault detection, fault location (cabinet number), fault cause, fault status (occurrence), and fault handling reminder. When a cabinet has both emergency and non-emergency faults, the fault information is displayed in separate columns according to the fault type. Emergency fault information is displayed at the top of the fault information bar, and non-emergency fault information is displayed below.

[0047] S230: When the operating status of the cabinet included in the rod control and position system is in a fault state, extract the fault information of the faulty operating cabinet according to the operating information, configure the fault handling plan of the cabinet according to the fault information, and push the fault handling plan to the operation and maintenance personnel.

[0048] In this embodiment, when a cabinet malfunctions, clicking the "View Details" button will take you to the corresponding cabinet status monitoring details interface (taking the power cabinet as an example), where you can view the operating status of each component within the cabinet. For example... Figure 4 As shown, the interface displays rack components in functional columns. The fault information column displays: fault type, time the fault was detected, fault location (rack number and specific component number), fault cause, fault status (occurring), and fault handling reminders. The page also includes "Fault Log," "Fault Handling," and "Back" buttons. Optionally, the fault information may also include the fault occurrence time, fault location, and fault cause.

[0049] In one embodiment, a fault handling plan for the cabinet is configured based on fault information, and the fault handling plan is pushed to the operation and maintenance personnel. Specifically, the fault type of each component of the cabinet is determined based on the fault information, a fault handling plan is configured based on the fault type of the component, and the urgency of the fault is determined based on the fault type.

[0050] Configure appropriate fault handling prompts based on the urgency of the fault, and push the fault handling plan and prompts to the maintenance personnel.

[0051] Specifically, when a server rack malfunctions and requires troubleshooting, clicking the "Troubleshooting" button will take you to the troubleshooting solution interface, such as... Figure 6 As shown, the fault handling solutions are displayed in columns according to fault type, with the operation steps for emergency fault handling solutions displayed at the top of the page and those for non-emergency fault handling solutions displayed at the bottom. There are two push methods: one is displaying the information on the local host computer, and the other is pushing the fault information and fault handling solutions to the intelligent receiving terminal unit of the maintenance personnel via the system's wireless network.

[0052] S240: After receiving the instruction that the fault handling scheme has been executed, the current operating information of the cabinet is re-acquired, the current operating information of the cabinet is parsed, the current operating status of the cabinet is obtained, and it is determined whether the current operating status of the cabinet is faulty. If it is still faulty, other fault handling schemes for the cabinet are configured according to the current fault information until the cabinet is fault-free, and the fault monitoring and handling of the rod control position system is completed.

[0053] Specifically, after the maintenance personnel complete the fault handling, they click the "Retest" button to enter the rack's current status detection program. The retest process will last a few seconds, and a retest waiting prompt window will pop up. After the retest is completed, they will return to the corresponding rack status monitoring details interface. If the fault has been eliminated after handling, the corresponding fault will disappear from the rack status monitoring details interface. Figure 7 As shown, the corresponding fault disappears on the rack status monitoring details interface (taking the handling of LC plug-in removal fault as an example); if the fault still exists after handling, you can click the "Fault Handling" button again to select other fault handling solutions to operate until the fault is eliminated.

[0054] In one embodiment, the method further includes: recording all fault information of the racks included in the rod control system during operation, in reverse chronological order of the fault occurrence time. In this embodiment, recording all fault information occurring during system operation can provide data reference for system maintenance, periodic inspections, and status assessments.

[0055] In summary, the method for fault monitoring and handling of the rod control and position system provided in this embodiment of the invention can monitor the operating information of the main cabinets in the rod control and position system. By parsing this operating information, the operating status of the logic cabinet, power cabinet, processing cabinet, measurement cabinet, and test cabinet can be viewed. When a cabinet malfunctions, a corresponding fault handling plan is configured based on the fault information. Different fault types are categorized by urgency and severity to prompt maintenance personnel to handle the fault promptly. After maintenance personnel complete the fault handling according to the steps of the fault handling plan, the operating status of the cabinet is retested to determine whether the fault has been successfully eliminated. If the fault persists after one maintenance operation using the fault handling plan, another fault handling plan is selected for a second operation until the fault is eliminated. This method can guide maintenance personnel to conduct fault diagnosis in an orderly manner and quickly and accurately eliminate faults, further improving the safety performance of nuclear power plants.

[0056] The present invention also provides an apparatus for monitoring and handling faults in a rod control and position system, which can be used to perform the method for monitoring and handling faults in a rod control and position system as described in any of the above embodiments of the present invention.

[0057] Please see Figure 8 , Figure 8 This diagram illustrates the principle block diagram of a rod control position system fault monitoring and handling device provided in an embodiment of the present invention. The device includes:

[0058] The first processing unit 810 is used to acquire the operation information of the cabinets included in the rod control and positioning system, wherein the cabinets include logic cabinets, power cabinets, processing cabinets, measurement cabinets, and test cabinets; parse the operation information to obtain the operation status of the cabinets included in the rod control and positioning system; when the operation status of the cabinets included in the rod control and positioning system is a fault state, extract the fault information of the faulty operating cabinet according to the operation information, configure the fault handling plan of the cabinet according to the fault information, and push the fault handling plan to the operation and maintenance personnel.

[0059] The second processing unit 820 is used to, after receiving the instruction that the fault handling scheme has been executed, re-acquire the current operating information of the cabinet, parse the current operating information of the cabinet, obtain the current operating status of the cabinet, determine whether the current operating status of the cabinet is faulty, and if it is still faulty, continue to configure other fault handling schemes for the cabinet according to the current fault information until the cabinet is fault-free, and complete the fault monitoring and handling of the rod control position system.

[0060] Optionally, the first processing unit is specifically used to: determine the fault type of each component of the cabinet based on the fault information, configure a fault handling plan based on the fault type of the component, and determine the urgency of the fault based on the fault type; configure corresponding fault handling operation prompts based on the urgency of the fault, and push the fault handling plan and operation prompts to the maintenance personnel.

[0061] Optionally, the fault information may also include the time of fault occurrence, the location of fault, and the cause of fault.

When a cabinet fails, it configures a corresponding fault handling plan based on the fault information, and prompts maintenance personnel to handle the fault in a timely manner according to the urgency and severity of different fault types. After the maintenance personnel complete the fault handling according to the fault handling plan steps, the operating status of the cabinet is retested to determine whether the fault has been successfully eliminated. If the fault still exists after performing maintenance according to the fault handling plan once, other fault handling plans are selected for a second operation until the fault is eliminated. This can guide maintenance personnel to carry out fault troubleshooting work in an orderly manner and eliminate faults quickly and accurately, further improving the safety performance of nuclear power plants.

The processor may be a central processing unit (CPU), or it may be other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), off-the-shelf programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. It is the computing core and control core of the terminal, and it is suitable for implementing one or more instructions. Specifically, it is suitable for loading and executing one or more instructions in the computer storage medium to realize the corresponding method flow or corresponding function.
