Technical Field

[0001] The present application relates to the technical field of nuclear power plant safety training, and in particular to a training system and method for simulating a nuclear power plant. Background Art

[0002] Currently, nuclear power plant safety training focused on preventing human error primarily involves theoretical lectures and simple simulated operation training. Theoretical lectures primarily explain nuclear power plant safety regulations and the meaning of signs, giving trainees a solid theoretical understanding of preventing human error. Simulated operation training involves having trainees practice simple equipment operation in simulated scenarios, such as identifying and applying certain signs.

[0035] In the following description, specific details such as specific system structures and techniques are provided for purposes of illustration rather than limitation to facilitate a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obscuring the description of the present application with unnecessary detail.

[0036] It should be understood that when used in the present specification and the appended claims, the term "comprising" indicates the presence of described features, integers, steps, operations, elements and / or components, but does not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or collections thereof.

[0037] It will also be understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0038] As used in this specification and the appended claims, the term "if" can be interpreted as "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "upon determination" or "in response to determining" or "upon detection of [described condition or event]" or "in response to detecting [described condition or event]," depending on the context.

[0039] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0040] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof all mean "including but not limited to," unless otherwise specifically emphasized.

[0041] It should be noted that the data collection process (such as the facial image collection process, the training data collection process, etc.) / feature extraction process involved in this application is carried out with the knowledge and permission of the students, that is, the data collection process / feature extraction process complies with the requirements of laws and regulations and does not constitute an act that harms the public interest.

[0042] It is understandable that in terms of nuclear power plant safety training, the current training system used to simulate nuclear power plants lacks intelligence and cannot provide timely and targeted feedback on the correctness of training operations, which affects the training effect of trainees. For example, the scenarios of theoretical lectures and simple simulated operation training are quite different from the actual working scenarios of nuclear power plants. As a result, due to the lack of authenticity of the training scenarios, it is difficult for trainees to truly feel the role and importance of signs in the complex environment of nuclear power plants during the training process, resulting in poor training results. When facing real scenarios in actual work, operational errors caused by unfamiliarity with signs are still likely to occur.

[0043] At the same time, the training content on "using signs" in traditional training systems used to simulate nuclear power plants is limited to simple explanations and basic applications of common signs. It lacks in-depth training on various complex sign situations and the relationship between signs and actual operations. The training content is relatively simple. For example, trainees lack understanding of the changes in signs under some special working conditions and the meaning of special signs, and are unable to cope with complex situations in actual work.

[0044] Furthermore, traditional training systems for simulated nuclear power plants are mostly one-way knowledge transfer, failing to provide targeted training tailored to each trainee's specific needs. Furthermore, the training process lacks interaction between trainees and between trainees and the training equipment, making it difficult to stimulate their enthusiasm and initiative, hindering training effectiveness.

[0045] Based on this, this embodiment provides a training system for simulating nuclear power plants, which integrates mechanical design and electronic technology. By simulating the actual scenes of nuclear power plants and setting up diversified signs and operation tasks, it effectively improves the nuclear power plant trainees' ability to identify, understand and apply signs, reduces the risk of human errors, and ensures the safe and stable operation of nuclear power plants. It has the characteristics of high scene simulation, flexible training methods, and significant training effects, and has important application value in the field of nuclear power plant personnel training.

[0046] Figure 1 This is a structural block diagram of a training system for simulating a nuclear power plant provided by an embodiment of the present application. Figure 1 As shown, the system includes:

[0047] Maintenance training equipment 1, used to collect training data of trainees performing maintenance operations on a simulated nuclear power plant;

[0048] The data processing device 2 is in communication with the maintenance training device 1 and is used to perform abnormality detection on the training data to obtain a detection result of the training data; and when the detection result indicates that the trainee's maintenance operation is abnormal, the detection result carrying the abnormal operation data is sent to the maintenance training device 1 and the abnormal operation data is displayed;

[0049] The maintenance training device 1 is also used to issue an audible and visual alarm based on the abnormal operation data through a built-in speaker and indicator light when receiving a detection result carrying abnormal operation data sent by the data processing device 2.

[0050] Among them, the maintenance training equipment 1 can be considered as a device for training trainees to perform simulated nuclear power plant maintenance. For example, the maintenance training equipment 1 can simulate some structural components of an actual nuclear power plant, and the purpose of training can be achieved by trainees performing maintenance operations on the simulated structures.

[0051] This embodiment does not limit the specific composition of the maintenance training equipment 1, and can be configured according to actual training needs. For example, the maintenance training equipment 1 can be configured with a specific circuit structure that simulates a nuclear power plant in different maintenance scenarios to enable trainees to be trained in different maintenance scenarios.

[0052] The data processing device 2 can establish a communication connection with the maintenance training device 1 and can be responsible for data processing. The data processing device 2 can be an independent processing device or can be composed of multiple devices with different responsibilities. For example, the data processing device 2 can include a control device and a host computer. The control device can be responsible for coordinating the operation of each device, such as receiving and processing training data from the maintenance training device 1 and transmitting relevant data information to the host computer. Specifically, the training data can be detected for abnormalities to obtain the detection results of the training data. Different control logics can be executed according to different detection results. For example, when the detection results indicate that the trainee's maintenance operation is abnormal, the detection results carrying abnormal operation data can be sent to the maintenance training device 1. The abnormal operation data can be used to indicate the abnormal location of the trainee's maintenance operation. The host computer can provide an intuitive operation interface to facilitate monitoring the trainee's maintenance operation, viewing error information, etc., such as displaying the abnormal operation data so that the instructor can teach and manage the trainee's maintenance operation based on the abnormal operation data.

[0053] In actual applications, first, the maintenance training equipment 1 can collect training data of trainees performing maintenance operations on simulated nuclear power plants. The specific type of training data is not limited. For example, depending on the specific structure of the maintenance training equipment 1, different types of training data can correspond. For example, when the maintenance training equipment 1 is equipped with an image acquisition device, the training data can be image action data, etc.

[0054] Then, the maintenance training device 1 can transmit the training data to the data processing device 2 through a communication connection with the data processing device 2. The data processing device 2 performs anomaly detection on the training data and processes the training data to obtain the detection result. When the detection result indicates that the trainee's maintenance operation is abnormal, the data processing device 2 sends the detection result with the abnormal operation data to the maintenance training device 1. For example, the data processing device 2 can directly output the detection result of the training data based on the detection model, or it can realize the anomaly detection of the training data by comparing the training data with the standard data. The detection model can be a pre-trained neural network model for performing anomaly detection on the training data.

[0055] Finally, upon receiving the detection result carrying abnormal operation data sent by the data processing device 2, the maintenance training device 1 can issue an audible and visual alarm based on the abnormal operation data through the built-in speaker and indicator light.

[0056] In another embodiment of the present application, the maintenance training equipment can be further optimized as: a mechanical maintenance training device, which is equipped with an air duct structure simulating a nuclear power plant, wherein the air duct structure includes multiple nuclear power air ducts, and each nuclear power air duct is sequentially installed with an air valve module, a heating module and a sensor module connected by detachable pipes.

[0057] As an example, the training data includes first module position data; the mechanical maintenance training device is further configured with:

[0058] The first maintenance chip is used to collect the first module position data of the module to be repaired. The module to be repaired includes at least one of a detachable pipe, a wind valve module, a heating module and a sensor module. The first module position data is used to record the position of the module to be repaired after being disassembled and reinstalled by the trainee.

[0059] In a specific embodiment, Figure 2 This is a structural block diagram of a mechanical maintenance training device provided by an embodiment of the present application. Figure 2 As shown, referring to the air duct structure of a nuclear power plant, multiple (three are taken as an example in the figure) nuclear power air ducts can be carefully designed in the mechanical maintenance training device. Each nuclear power air duct is sequentially installed with a damper module (such as "001VA"), a heating module (such as "010RS"), and a sensor module (such as "110JR"). The corresponding modules on different nuclear power air ducts have the same appearance, but each module has a unique identity document (ID); the nuclear power air ducts can be connected by 9 detachable pipes, and the pipes are affixed with labels that are easily confused.

[0060] Furthermore, a first maintenance chip is configured behind each of the different nuclear power air ducts. The first maintenance chip can be understood as a positioning chip, which is used to collect the first module position data of at least one of the detachable pipes, air valve modules, heating modules and sensor modules, that is, the position of each module after being disassembled and reinstalled by the trainee. On this basis, a mechanical maintenance training device is designed to install multiple air ducts on different guide rails, which can facilitate the trainees' disassembly and assembly training and greatly reduce the damage to the equipment during training. At the same time, by designing a module with an independent ID on each air duct and accurately positioning it through Radio Frequency Identification (RFID) technology, it can be achieved that if the trainees make an installation error or inadequate installation during the installation process, an alarm can be triggered and the error information can be sent to the host computer.

[0061] Among them, in order to simulate the nuclear power operation process, such as Figure 2The mechanical maintenance training device also features an air switch and a rotary switch (i.e., "001AV" and "001JA"). Trainees are instructed to perform these disassembly and installation operations. At the start of the training, the air switch and rotary switch are turned off and labeled with maintenance-related labels. Maintenance labels are also affixed to the nine modules. Trainees are then required to remove modules and pipes in a given order, marking each removed item with a designated maintenance label and placing it in its designated location. Failure to do so will make it difficult to distinguish the installation locations of the modules and pipes. During installation, trainees must strictly install each module and pipeline according to the position indicated by the mark. After the installation is completed, the test link can be started, and the test-related marks can be hung on the air switch and the knob switch, and the switch can be turned on to start the test. At this time, the control device of the data processing equipment can perform an abnormality detection on the first module position data of the module to be repaired, and when the test result indicates that the trainee's maintenance operation is abnormal (that is, the module to be repaired is installed incorrectly or not in place), the test result carrying the abnormal operation data is sent to the mechanical maintenance training device, and the mechanical maintenance training device can trigger an audible and visual alarm, such as through Figure 2 The nine indicator lights ("001AA"-"098AA") in the machine will give a light alarm. If the test is qualified, that is, the test result indicates that there is no abnormality in the trainee's maintenance operation, the trainee can remove the maintenance labels of each module, the test labels on the air switch and the knob switch to complete the maintenance work. Each trainee must repeat the above operation more than 3 times and operate in accordance with the regulations to be considered qualified in the mechanical maintenance training device. During the training process, the above method can stimulate the trainees' interest in the use of labels, which can greatly improve the trainees' attention to and application ability of labels.

[0062] Figure 3 This is an interactive interface diagram of a host computer provided in one embodiment of the present application, such as Figure 3 As shown, the host computer interface of the data processing equipment can display the corresponding air inlet 1, air duct 1, and air outlet 1 for the first nuclear power air duct, the corresponding air inlet 2, air duct 2, and air outlet 2 for the second nuclear power air duct, and the corresponding air inlet 3, air duct 3, and air outlet 3 for the third nuclear power air duct. Each of the nine modules can also have corresponding indicator lights. When there is an error or incomplete installation of a module, the error location can be displayed and the error information can be recorded. For example, the indicator light corresponding to the module can be red, and the indicators corresponding to other modules can be green. On this basis, the host computer can be developed to effectively display the trainee's operation data and error information, facilitating instructors' teaching evaluation and analysis. At the same time, the trainee's training data can be stored and managed, providing data support for subsequent training improvements.

[0063] As another example, the training data further includes first image motion data and / or first sound data; and the mechanical maintenance training device is further configured with:

[0064] The first image acquisition device is used to acquire first image action data of the trainee disassembling and reassembling the module to be repaired;

[0065] And / or a first sound collecting device, used to collect first sound data of the trainee disassembling and reinstalling the module to be repaired.

[0066] In order to realize intelligent training, this embodiment can also add motion recognition and voice recognition, that is, a first image acquisition device can be configured in the mechanical maintenance training device to collect the first image motion data of the trainees performing disassembly and reinstallation, and a first sound acquisition device can be configured in the mechanical maintenance training device to collect the first sound data of the trainees performing disassembly and reinstallation.

[0067] Accordingly, the data processing device can perform anomaly detection on the collected first image motion data and / or first sound data. If the detection result indicates that the trainee's maintenance operation is abnormal, the detection result, along with the abnormal operation data, can be transmitted to the mechanical maintenance training device, causing the mechanical maintenance training device to issue an audible and visual alarm indicating the abnormal operation data through a built-in speaker and indicator light. Furthermore, by incorporating motion recognition and voice recognition into the training system, the human error rate during trainee operation of a nuclear power plant can be effectively reduced, effectively enhancing the intelligent training system, effectively ensuring the safe and stable operation of the nuclear power plant, and laying a solid foundation for its safe production.

[0068] For example, during nuclear power plant maintenance, a roll call system is required. This system can be a key safety measure, ensuring the accuracy and safety of the operational process. For example, during nuclear power plant maintenance, the roll call system emphasizes real-time verification of the operational process and is often used in scenarios requiring multi-person coordination, such as switching operations. The operator reads out the instructions, and the supervisor repeats them item by item, verifying the equipment number and status. After both parties confirm that they are correct, the instructions are carried out. This effectively reduces the risk of incorrect operation and ensures the safe conduct of maintenance work. Specifically, each step should be read out loud (and recorded for future reference if necessary), correctly executed under the supervision of a supervisor, and the operation time and steps recorded. In other words, the roll call system requires the operator to read out the instructions, and the supervisor to repeat and verify the equipment status, ensuring that each step is accurate. This system is not only applicable to switching operations, but is also widely used in other maintenance scenarios requiring multi-person coordination.

[0069] In another embodiment of the present application, the maintenance training equipment is further optimized into: an electrical instrument maintenance training device, which is configured with a motor circuit simulating a nuclear power plant, wherein the motor circuit includes a relay module and multiple wiring terminals, and each wiring terminal is equipped with multiple cables carrying unique identifiers.

[0070] As an example, the training data includes the second module position data; the electrical instrument maintenance training device is further configured with:

[0071] The second maintenance chip is used to collect the second module position data of the module to be repaired. The module to be repaired includes a cable and / or a relay module. The second module position data is used to record the position of the module to be repaired after being disassembled and reinstalled by the trainee.

[0072] In a specific embodiment, Figure 4 This is a structural block diagram of an electrical instrument maintenance training device provided by an embodiment of the present application. Figure 4 As shown, referring to the maintenance process for nuclear power plant motor circuits, two terminal blocks and four relay modules can be designed in the electrical and instrument maintenance training device. Each terminal block can be equipped with 12 cables with unique IDs, and adjacent cables are numbered very similarly. The four relays have the same appearance, but the internal circuitry has been modified to have independent IDs. This ensures that trainees will not be able to complete the installation successfully if they do not use the correct identification during disassembly and assembly.

[0073] Furthermore, a second maintenance chip is located behind each module to be repaired. This second maintenance chip can be understood as a positioning chip, used to collect the second module position data of the cable and / or relay module, that is, the position of each module after the trainee has disassembled and reinstalled it. Based on this, two 12-channel independent encoding circuits and four identical relays were designed using an identification training device for electrical instrument maintenance. The internal circuits of the four relays were modified to give each relay a unique ID. This effectively collects various data from the trainee during the training operation, monitors and alarms for operational or installation errors, and transmits error location data to the host computer.

[0074] Likewise, to simulate nuclear power operations, e.g. Figure 4 The electrical instrument maintenance training device can also be provided with an air switch and a knob switch (i.e. "906AV", "101JA"). The specific process of the trainees performing disassembly and installation operations may include: at the beginning of the training, turning off the air switch and the knob switch, hanging maintenance-related labels on them, and at the same time sticking maintenance labels on the two terminal blocks and four relays.

[0075] Task 1: The trainees need to remove the cables on the right side of the first terminal block in order, put the removed cables into the wire sleeves, and mark the cables and terminals with labels. After the disassembly is completed, the instructor shuffles the order of the cables, and the trainees need to connect the cables according to the labels. After the trainees have connected all the cables to the first terminal block, they can hang test labels on the air switch and the knob switch, and turn on the knob switch and the air switch. If the wiring sequence is incorrect, the electrical instrument maintenance training device will trigger the corresponding sound and light alarm, and display the alarm location on the host computer, and record the error information. If the electrical instrument maintenance training device does not trigger the alarm, you can turn off the air switch and the knob switch, hang a maintenance label on the air switch, remove the maintenance label of the first terminal block, and proceed to Task 2.

[0076] Task 2: Trainees need to remove the cables to the right of the second terminal block in order, put on the wire sleeves, mark the cables and terminals with labels, and change the cable order according to the operating requirements. After the trainees have connected all the cables to the second terminal block, they can hang test labels on the air switch and the knob switch, and turn on the knob switch and the air switch. If the wiring sequence is incorrect, the electrical instrument maintenance training device will trigger an audible and visual alarm, display the alarm location on the host computer, and record the error information. If the electrical instrument maintenance training device does not alarm, you can turn off the air switch and the knob switch, hang a maintenance label on the air switch, remove the maintenance label on the second terminal block, and proceed to Task 3.

[0077] Task three: Trainees need to remove four relays in sequence, mark them with maintenance labels, and place them in designated storage boxes. After disassembly, install them in the order of the labels. After installation, hang test labels on the air switch and the knob switch, and turn on the knob switch and the air switch. If the relay is installed incorrectly, the electrical instrument maintenance training device will trigger the corresponding sound and light alarm, and display the alarm location on the host computer and record the error information. If there is no alarm, turn off the air switch and the knob switch, remove the label on the air switch and the maintenance label on the relay, and the maintenance is complete. The above three tasks need to be repeated three times each. The training is considered qualified only if there is no alarm on the electrical instrument maintenance training device each time.

[0078] As another example, the training data further includes second image motion data and / or second sound data; and the electrical instrument maintenance training device is further configured with:

[0079] The second image acquisition device is used to acquire second image action data of the trainee disassembling and reassembling the module to be repaired;

[0080] And / or a second sound collection device, used to collect second sound data of the trainee disassembling and reinstalling the module to be repaired.

[0081] For intelligent training, this embodiment can also add motion recognition and voice recognition, that is, a second image acquisition device can be configured in the electrical instrument maintenance training device to collect the second image motion data of the trainees performing disassembly and reinstallation, and a second sound acquisition device can be configured in the electrical instrument maintenance training device to collect the second sound data of the trainees performing disassembly and reinstallation.

[0082] Accordingly, the data processing device can perform anomaly detection on the collected second image motion data and / or second sound data. If the detection result indicates that the trainee's maintenance operation is abnormal, the detection result, along with the abnormal operation data, is transmitted to the electrical instrument maintenance training device, causing the device to issue an audible and visual alarm indicating the abnormal operation data through its built-in speaker and indicator light. Furthermore, by incorporating motion and voice recognition into the training system, the human error rate during trainees' actual nuclear power plant operations can be effectively reduced, effectively enhancing the intelligent training system, effectively ensuring the safe and stable operation of the nuclear power plant, and laying a solid foundation for its safe production.

[0083] As can be seen from the above description, the training system for simulating a nuclear power plant provided in this embodiment is primarily composed of a mechanical maintenance identification training device (i.e., a mechanical maintenance training device), an electrical instrumentation maintenance identification training device (i.e., an electrical instrumentation maintenance training device), a control system, and a host computer interface (i.e., a data processing device). To mimic the daily maintenance environment of a nuclear power plant, the mechanical maintenance identification training device can simulate a nuclear power plant mechanical maintenance scenario, including structures such as air ducts and modules. Guide rails facilitate easy assembly and disassembly, and RFID radio frequency communication and a single-chip microcomputer control system provide real-time monitoring of module installation. The electrical instrumentation maintenance identification training device can also simulate an electrical instrumentation maintenance scenario, equipped with different training modules. Circuit operation is monitored via independent encoding circuits and modified relays. Similarly, the single-chip microcomputer control system collects data and implements alarm functions. The control system is responsible for coordinating the operation of each component, receiving and processing data from the training device, and transmitting relevant information to the host computer. The host computer interface provides an intuitive operating interface for the instructor, allowing the instructor to clearly observe the trainee's operations, facilitate monitoring the trainee's operations, and view error messages. During the training process of each scenario, each training device is designed with a series of scenarios where errors are easy to make, so that if trainees do not use the signs in a standardized manner during the training process, they will not be able to complete the operation correctly. Only by using the signs correctly can the training tasks be completed accurately. Therefore, during the training process, the trainees' awareness of using signs is strengthened and their ability to use signs is improved.

[0084] In summary, the training system for simulating a nuclear power plant provided in this embodiment highly simulates the actual maintenance environment of a nuclear power plant in terms of training scenarios, allowing trainees to experience the role of labels in real work scenarios in an immersive way, effectively improving the trainees' ability to adapt to complex scenarios. In terms of training content, based on the requirements for labels used in the nuclear power maintenance process, it covers various complex labeling situations and the deep connection between labels and actual operations. It not only meets the needs of training and allows trainees to fully master labeling knowledge, but also helps nuclear power trainees improve their ability to identify, understand and apply labels, effectively reducing operational errors caused by trainees' unfamiliarity with labels, reducing the incidence of equipment failures, and reducing equipment maintenance time and costs. In terms of training methods, by setting up error-prone scenarios, intelligent monitoring and alarms, and host computer interaction functions, personalized and interactive training is achieved, fully mobilizing the trainees' enthusiasm and initiative in learning, and greatly improving the training effect.

[0085] Therefore, the training system for simulating a nuclear power plant provided in this embodiment can be widely used in new employee orientation training, on-the-job employee skills improvement training, and emergency drill training for power plants. This method can stimulate trainees' interest in the use of signs and significantly improve their attention to and ability to apply signs. For example, during the new employee orientation phase, it can help new employees quickly become familiar with the various signs in the nuclear power plant work environment, master the correct sign usage methods, and shorten the time it takes for them to adapt to their jobs. For on-the-job employees, regular use of the training system for training can strengthen their memory and application of signs and continuously improve their operational skills. In emergency drill training, simulating sign usage scenarios in emergency situations improves employees' ability to accurately identify and use signs in emergency situations, enhancing the power plant's ability to respond to emergencies. As employees' operational skills improve, the workflow becomes smoother and more efficient, thereby improving the overall production efficiency of the power plant. At the same time, due to the reduction in human error, the safety and stability of the nuclear power plant is enhanced, production interruptions caused by safety accidents are reduced, and the power plant's continuous and stable power generation is guaranteed, providing a reliable power supply to society, indirectly promoting the development of related industries, and playing a positive role in the stable operation of the social economy.
