[0017] Figure 2 It is a structural diagram of another nuclear power plant accident intelligent processing navigation system provided in an embodiment of the present application. DETAILED DESCRIPTION

[0018] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0019] The following describes a nuclear power plant accident intelligent processing navigation system according to an embodiment of the present application with reference to the accompanying drawings.

[0020] Figure 1 It is a structural schematic diagram of a nuclear power plant accident intelligent processing navigation system provided in an embodiment of the present application.

[0021] like Figure 1 As shown, the nuclear power plant accident intelligent processing navigation system 1000 may include: a data receiving module 100 , an intelligent processing navigation module 200 and a human-computer interaction interface 300 .

[0022] The data receiving module 100 is used to receive the status information and alarm information of the nuclear power unit sent by the distributed control system DCS.

[0023] It should be noted that the data receiving module 100 establishes a stable communication connection with the distributed control system (DCS) of the nuclear power plant to receive the status information and alarm information of the nuclear power unit sent by the DCS.

[0024] It should be noted that the present application does not limit the status information of the nuclear power unit. Optionally, the status information of the nuclear power unit includes but is not limited to status information such as reactor power, coolant temperature and steam generator pressure.

[0025] It should be noted that the present application does not limit the alarm information of the nuclear power unit. Optionally, the alarm information of the nuclear power unit may be alarm information for any status information of the nuclear power unit.

[0026] For example, with respect to the temperature alarm information of a nuclear power unit, when the coolant temperature is higher than a preset temperature threshold, an alarm message is generated, and the DCS sends the temperature alarm information of the nuclear power unit to the data receiving module.

[0027] The intelligent processing navigation module 200 is used to obtain the target electronic procedure to be executed by the nuclear power unit and the execution navigation path of the target electronic procedure according to the status information and the alarm information.

[0028] In an embodiment of the present application, the intelligent processing navigation module can call a pre-built expert library to identify the status information and alarm information of the nuclear power unit to determine the current target accident status and target accident type of the nuclear power unit, and then obtain the target electronic procedures to be executed by the nuclear power unit and the execution navigation path of the target electronic procedures based on the target accident status and target accident type.

[0029] The execution navigation path includes the execution order, jump conditions, etc. of the target electronic procedures to be executed.

[0030] It should be noted that by summarizing and processing information such as the accident handling experience of various experts, an expert database is constructed. The expert database stores the characteristic parameters of various design basis accidents and poor design basis accidents, as well as the corresponding handling procedures and the execution navigation paths of the handling procedures. The expert database provides intelligent support for the intelligent handling navigation system for nuclear power plant accidents proposed in this application.

[0031] Among them, the human-computer interaction interface 300 is used to display the target electronic procedure and the execution navigation path of the target electronic procedure, receive the accident handling instructions input by the operator, call the target electronic procedure from the electronic procedure system according to the accident handling instructions, and execute the target electronic procedure according to the execution navigation path to handle the accident of the nuclear power unit.

[0032] The human-machine interaction interface 300 is a window for the nuclear power plant accident handling navigation system 1000 to interact with the operator.

[0033] In the embodiment of the present application, the human-computer interaction interface 300 can intuitively display the target electronic procedure and the execution navigation path of the target electronic procedure. The human-computer interaction interface 300 establishes a connection with the electronic procedure system, receives the accident handling instructions input by the operator, calls the target electronic procedure from the electronic procedure system according to the accident handling instructions, and executes the target electronic procedure according to the execution navigation path to handle the accident of the nuclear power unit.

[0034] The present application proposes a nuclear power plant accident intelligent processing navigation system, comprising: a data receiving module, an intelligent processing navigation module and a human-computer interaction interface, wherein the data receiving module is used to receive the status information and alarm information of the nuclear power unit sent by the distributed control system DCS, the intelligent processing navigation module is used to obtain the target electronic procedure to be executed by the nuclear power unit and the execution navigation path of the target electronic procedure according to the unit status information and alarm information, the human-computer interaction interface is used to display the target electronic procedure and the execution navigation path of the target electronic procedure, receive the accident processing instruction input by the operator, call the target electronic procedure from the electronic procedure system according to the accident processing instruction, and execute the target electronic procedure according to the execution navigation path to process the accident of the nuclear power unit. Therefore, the nuclear power plant accident intelligent processing navigation system provided by the present application minimizes the operator's misoperation and misjudgment in the process of nuclear power plant accident processing, improves the timeliness and accuracy of nuclear power plant accident processing, and is conducive to the safe and stable operation of the nuclear power plant.

[0035] Figure 2 It is a structural schematic diagram of a nuclear power plant accident intelligent processing navigation system provided in an embodiment of the present application.

[0036] like Figure 2As shown, the nuclear power plant accident intelligent processing navigation system 2000 may include: a data receiving module 100 establishes a connection with the distributed control system DCS of the nuclear power plant through a communication interface to receive the status information and alarm information of the nuclear power unit sent by the distributed control system DCS; the intelligent processing navigation module 200 obtains the target electronic procedure to be executed by the nuclear power unit and the execution navigation path of the target electronic procedure according to the status information and alarm information by calling the expert library; the human-computer interaction interface 300 establishes a connection with the electronic procedure system through the electronic procedure drive interface; according to the instructions input by the operator, the target electronic procedure can be called from the electronic procedure system, and the target electronic procedure is executed according to the execution navigation path to handle the accident of the nuclear power unit.

[0037] like Figure 2 As shown, in some embodiments, the intelligent processing module 200 is also used to: continuously monitor the process of executing the target electronic procedure according to the execution navigation path, and for the i-th target electronic procedure corresponding to the execution navigation path, in response to monitoring that the current state of the nuclear power unit deviates from the safe state after executing the i-target electronic procedures, update the target electronic procedure and the execution navigation path of the target electronic procedure until the nuclear power unit is restored to a safe state, wherein i is a natural number greater than or equal to 1.

[0038] It should be noted that by continuously monitoring the process of executing the target electronic procedure according to the execution navigation path, the accident handling process can be understood in real time. When it is monitored that the current state of the nuclear power unit deviates from the safe state or even a more serious accident occurs, the target electronic procedure and the execution navigation path of the target electronic procedure are dynamically adjusted and optimized to achieve updates until the nuclear power unit is restored to a safe state, for example: a safe cold shutdown state.

[0039] like Figure 2 As shown, in some embodiments, the human-computer interaction interface 300 is also used to: in response to the target electronic procedure and the execution navigation path of the target electronic procedure not being updated, jump to the i+1th target electronic procedure corresponding to the execution navigation path; in response to the target electronic procedure and the execution navigation path of the target electronic procedure being updated, display the updated target electronic procedure and the execution navigation path of the updated target electronic procedure.

[0040] It should be noted that if the target electronic procedure and the execution navigation path of the target electronic procedure are not updated, it means that executing the target electronic procedure according to the execution navigation path makes the state of the nuclear power unit tend to be safe. The human-computer interaction interface 300 will automatically jump to the i+1th target electronic procedure corresponding to the execution navigation path to prompt the operator of the jump status of the target electronic procedure.

[0041] It should be noted that if the target electronic procedure and the execution navigation path of the target electronic procedure are updated, it means that the current state of the nuclear power unit deviates from the safe state or even a more serious accident occurs. The human-computer interaction interface 300 will immediately display the updated target electronic procedure and the updated execution navigation path to ensure that the operator can obtain the latest target electronic procedure and execution navigation path.

[0042] like Figure 2 As shown, in some embodiments, the human-machine interaction interface 300 is also used to: receive expert database maintenance instructions input by the operator, and update and maintain the expert database according to the expert database maintenance instructions.

[0043] For example: when it is identified that there is unavailable content in the expert library, the operator enters a delete command in the human-computer interaction interface 300, and deletes the unavailable content in the expert library through the delete command; for another example: when it is identified that there is content that does not exist in the expert library, the operator enters a add command in the human-computer interaction interface 300, and adds the content that does not exist in the expert library to the expert library through the add command.

[0044] like Figure 2 As shown, in some embodiments, the human-computer interaction interface 300 is also used to: generate accident warning prompt information in response to an accident in a nuclear power unit, generate accident handling prompt information according to the execution navigation path of the target electronic procedure, and display the accident warning prompt information and the accident handling prompt information.

[0045] It should be noted that the present application does not limit the form of the accident warning prompt information, for example: light warning prompt information, voice warning prompt information and text warning prompt information.

[0046] For example, when the accident occurring in a nuclear power unit is "reactor temperature is too high", the text warning message "reactor temperature is too high!" can be displayed in a highlighted form on the interactive interface 300 with a flashing red light.

[0047] It should be noted that the present application does not limit the form of the accident handling prompt information, for example: text list form, voice form, and flowchart form, etc.

[0048] like Figure 2 As shown, in some embodiments, the human-computer interaction interface 300 is also used to: display the target accident type of the nuclear power unit and the execution status of the target electronic procedure, wherein the execution status includes at least an unexecuted state, an executed state, and an executing state.

[0049] like Figure 2As shown, in some embodiments, the human-machine interaction interface 300 is also used to: receive operation instructions input by the operator, and add, delete, modify and check the target electronic procedure and the execution navigation path of the target electronic procedure according to the operation instructions.

[0050] It should be noted that, through the human-machine interaction interface 300 , the operator can flexibly adjust and optimize the target electronic procedure and the execution navigation path of the target electronic procedure to flexibly adapt to different states and different accident types of the nuclear power unit.

[0051] like Figure 2 As shown, in some embodiments, the human-computer interaction interface 300 is also used to: receive a first accident handling instruction input by an operator, and generate a first target electronic procedure to be executed and an execution navigation path of the first target electronic procedure according to the first accident handling instruction.

[0052] It should be noted that, upon determining that an accident has occurred in a nuclear power unit, the operator inputs a first accident handling instruction in the human-machine interaction interface 300, and calls a first target electronic procedure from the electronic procedure system according to the first accident handling instruction to generate a first target electronic procedure to be executed and an execution navigation path of the first target electronic procedure to handle the accident of the nuclear power unit.

[0053] To sum up, the intelligent processing navigation system for nuclear power plant accidents provided by the present application, the intelligent processing navigation module can quickly and accurately judge the accidents of nuclear power units by calling the expert library, realize the rapid response and processing of design basis accidents and beyond design basis accidents of nuclear power plants, and determine the target electronic procedures and the execution navigation path of the target electronic procedures by calling the expert library, and display the target electronic procedures and the execution navigation path of the target electronic procedures to the operator in the human-computer interaction interface, provide navigation guidance for the operator's accident handling process, which is conducive to the operator to handle nuclear power plant accidents more promptly and accurately, and prevent the operator from making misoperations in accident judgment, electronic procedure execution or electronic procedure jump in a highly tense environment to the greatest extent, and prevent more serious accident consequences caused by misoperation, which is conducive to the safe and stable operation of nuclear power plants.
