Description

Technical Field

[0001] This invention relates to the field of nuclear power plant accident handling and recording technology, and in particular to an online recording system and method for important information in nuclear power plant accident procedures. Background Technology

[0002] Currently, nuclear power plant accident handling primarily relies on paper-based procedures and accompanying visual aids to implement accident mitigation strategies. During the execution of these procedures, operators manually record crucial parameters and information in a paper checklist for subsequent unit status assessment and on-site operational documentation. However, the paper checklist system, which relies on management procedures to control human behavior, lacks standardized marking methods. In accident situations, operators face significant pressure and workload, requiring extensive information management skills and placing high demands on their psychological resilience and professional competence. The large amount of information to be recorded in the checklist, coupled with the need to update procedures, increases the risk of omissions and errors, potentially triggering human error. Therefore, providing operators with a simple and accurate method for recording unit parameter information during accident situations has become a crucial research issue for nuclear power plant designers.

[0043] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0044] It should be noted that the flowcharts shown in the accompanying drawings are merely illustrative and do not necessarily include all content and operations / steps, nor do they necessarily have to be performed in the described order. For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0045] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0046] See Figure 1 The first embodiment of the present invention discloses an online recording system for important information in nuclear power plant accident procedures. The system includes: a data extraction module for acquiring unit parameters and / or information; the unit parameters and / or information can be acquired internally or input externally by the operator; a procedure recording module for determining whether an accident has occurred; if so, executing the data extraction module; a logic processing module for processing the unit parameters and / or information acquired by the data extraction module according to a first preset rule, and obtaining estimated unit parameters and / or information; it also compares the acquired unit parameters and / or information with the estimated unit parameters and / or information; if the comparison results are inconsistent, executing an alarm via an information display module; and an information display module for displaying the unit parameters and / or information acquired by the data extraction module, and also for issuing an alarm after a discrepancy is found between the unit parameters and / or information and the estimated unit parameters and / or information, and for providing an input interface for the operator. In some embodiments, the data extraction module triggers the DCS (Digital Control System) platform via a dedicated control to extract identified unit parameters and / or information according to the nuclear power plant's accident procedures. All identified unit parameters and / or information are preset and typically represent the unit parameters and / or information required to be processed in the nuclear power plant's accident procedures. In other embodiments, the operator can input operation information on the information display module according to the requirements of the accident procedures. The data extraction module is responsible for acquiring this operation information. For example, if an operation command to stop gas pump A is input on the information display module, the data extraction module will retrieve that gas pump A has stopped; or, if an operation command to close valve B is input on the information display module, the data extraction module will retrieve that valve B has been closed.

[0047] See Figure 2Furthermore, to prevent operators from repeatedly performing the same operation in a single incident to comply with multiple incident procedures, the logic processing module also detects whether the same information exists in the multiple procedures required for a single incident. If so, the system records the information whenever it is recorded in any procedure. For example, if an incident requires the execution of the following three procedures: Procedure 1, Procedure 2, and Procedure 3, and all three procedures require recording information C, then if Procedure 1 records information C, the logic processing module automatically records information C simultaneously in Procedure 2 and Procedure 3, without requiring the operator to switch procedures and record information C multiple times. Or, if an incident requires the execution of the following three procedures: Procedure 4, Procedure 5, and Procedure 6, and both Procedure 4 and Procedure 6 require recording information D, then if Procedure 4 records information D, the logic processing module automatically records information D in Procedure 6, without requiring the operator to switch procedures and repeatedly record information D.

[0048] Furthermore, to handle various types of data and information in the system, the data extraction module includes: an analog quantity extraction module for extracting analog quantities from unit parameters and / or information; a logic quantity extraction module for extracting logic quantities from unit parameters and / or information; an important information extraction module for extracting important information from unit parameters and / or information, which is the important information preset in the nuclear power plant accident procedures; and an operation order information extraction module for extracting operation order information from unit parameters and / or information. The operation order information includes the operation order content and the operation order execution status, which is input by the operator through the information display module. In some embodiments, the information display module also includes an analog quantity display module, a logic quantity display module, an important information display module, and an operation order information display module, respectively used to display analog quantities, logic quantities, important information, and operation order information, facilitating the operator's understanding of the overall accident situation.

[0049] Furthermore, to enable the marking or unmarking of unit parameters and / or information in the system as needed, the procedure recording module includes an operation record triggering module for recording unit parameters and / or information and sending them to the information display module, and an operation record cancellation module for canceling the recording of unit parameters and / or information and canceling the information display module. The operation record triggering module and the operation record cancellation module only operate on recording and canceling records within a single incident; they do not affect historical unit parameters and / or information formed in the system, nor do they affect already recorded unit parameters and / or information, and they do not delete information from the system. In some embodiments, the operation record cancellation module is only used to determine that an incident has not occurred and cancel the record of that incident in the incident list. The operation record triggering module is only used to determine that an incident is occurring and record that incident in the incident list.

[0050] Furthermore, to assist in calculations and perform necessary logical processing and judgments, the logic processing module includes: a digital control module for calculating and estimating unit parameters and / or information; a marking module for sending commands to display unit parameters and / or information to the information display module; a demarking module for sending commands to cancel the display of unit parameters and / or information to the information display module; and an information verification module for comparing the unit parameters and / or information with the estimated unit parameters and / or information. If they are inconsistent, an error alarm module is executed; if they are consistent, it is determined whether the unit parameters and / or information need to be marked. If so, the marking module is executed; if not, and the unit parameters and / or information are already displayed in the information display module, the demarking module is executed. After the command to display unit parameters and / or information is sent to the information display module, the unit parameters and / or information will be displayed in the corresponding position in the information display module. After the command to cancel the display of unit parameters and / or information is sent to the information display module, the already displayed unit parameters and / or information will be de-displayed. In some embodiments, the operator can directly input a command to cancel the display of unit parameters and / or information through the information display module, which is sent directly to the information display module, and can also cancel the display of already displayed unit parameters and / or information.

[0051] Furthermore, to facilitate the calculation and estimation of unit parameters and / or information and reduce the system's computational load, the logic processing module, in accordance with the first preset rule, processes the unit parameters and / or information obtained by the data extraction module, including: fixing the analog quantities in the unit parameters and / or information to initial values, and taking the real-time values ​​of the logical quantities in the unit parameters and / or information. In some embodiments, the analog quantities in the unit parameters and / or information may be fixed to another value or directly use the real-time values.

[0052] Furthermore, to enable operators to more intuitively understand accident and fault information, and to allow them to promptly input operation orders and other parameters and / or information requiring manual external input, the information display module includes: an error information alarm module, used to display and alarm on unit parameters and / or information that are inconsistent with the estimated unit parameters and / or information; a real-time information display module, used to display unit parameters and / or information consistent with the estimated unit parameters and / or information; and an information interaction module for manual information input. Operators can determine the location or cause of unit faults based on the information displayed on the error information alarm module, and judge the dynamic trends of other indicators in the unit based on the information displayed on the real-time information display module. Then, they can input operation commands in the information interaction module. If operation commands cannot be directly input, operators can manually operate the unit and then record the execution of the operation in the information interaction module.

[0053] Furthermore, to replace paper-based record books for storing relevant information about each accident and to facilitate tracing and retrieval, the system also includes: an information storage module for storing historical unit parameters and / or information during system operation; and an information query module for querying historical unit parameters and / or information stored in the system. Operators can input query commands through the information display module to retrieve the historical unit parameters and / or information stored in the system and access the necessary data.

[0054] See Figure 3 The second embodiment of the present invention constructs an online recording method for important information in nuclear power plant accident procedures, including the following steps: S1, determining whether an accident has occurred; if so, acquiring unit parameters and / or information; S2, performing logical operations, processing the acquired unit parameters and / or information according to a first preset rule, obtaining estimated unit parameters and / or information, and comparing the acquired unit parameters and / or information with the estimated unit parameters and / or information; S3, displaying the unit parameters and / or information at the corresponding location, and alarming for inconsistent unit parameters and / or information; wherein, the unit parameters and / or information can be acquired from within the system or input by the operator from outside.

[0055] Furthermore, in order to reduce the computational load, the unit parameters and / or information include at least one of analog quantities, logical quantities, important information, and operation order information; processing the obtained unit parameters and / or information according to the first preset rule includes: fixing the analog quantities in the unit parameters and / or information to initial values, and taking the real-time values ​​of the logical quantities in the unit parameters and / or information.

[0056] Furthermore, to prevent operators from repeatedly performing the same operation in a single incident to comply with multiple incident procedures, step S2 also includes: detecting whether the same information exists in the multiple procedures required for a single incident; if so, when the information is recorded in any procedure, the other procedures also record the information. For example, if an incident requires the execution of the following three procedures: Procedure 1, Procedure 2, and Procedure 3, and all three procedures require recording information C, then if information C is recorded in Procedure 1, the logic processing module automatically records information C simultaneously in Procedure 2 and Procedure 3, without requiring the operator to switch procedures multiple times to record information C.

[0057] Furthermore, in order to process various types of data and information in the system, step S1 includes the following steps: S11, extracting analog quantities from unit parameters and / or information; S12, extracting logical quantities from unit parameters and / or information; S13, extracting important information from unit parameters and / or information, wherein the important information is the important information preset in the nuclear power plant accident procedures; S14, extracting operation order information from unit parameters and / or information; wherein, the operation order information includes the operation order content and the operation order execution status, and the operation order execution status is input by the operator through the information display module.

[0058] Furthermore, to facilitate the calculation and estimation of unit parameters and / or information and reduce the system's computational load, the logic processing module processes the acquired unit parameters and / or information according to a first preset rule, including: fixing the analog quantities in the unit parameters and / or information to initial values, and taking the real-time values ​​of the logical quantities in the unit parameters and / or information. In some embodiments, the analog quantities in the unit parameters and / or information may be fixed to another value or directly use real-time values.

[0059] Furthermore, to replace paper-based record books for storing relevant information about each accident and facilitate tracing and querying, the method also includes the step: S4, saving unit parameters and / or information during the accident. Operators can input query commands to retrieve historical unit parameters and / or information saved in the system to access the required data.
