[0059] FIG. 1 is a diagram illustrating an example of a user using a VR (virtual reality)-based simulation device according to an embodiment of the present invention. As illustrated, the user can use the simulation device by using a head-mounted display (HMD) (110) and two controllers (120_1, 120_2). Here, the simulation device (not shown) is a device for training a secondary battery production worker (e.g., user), and may be a device for communicating with the HMD (110), controllers (120), etc., to acquire user behavior information, and providing VR-based content (e.g., images, videos, animations, etc.) that is executed or changed according to the acquired user behavior information. For example, the user can use a simulation device that implements an actual secondary battery production device in VR to learn how to use the secondary battery production device or to train methods to respond when quality degradation of the produced product occurs.

[0060] According to one embodiment, the simulation device receives the user’s gaze direction and gaze position identified from the HMD (110) and can display content associated with a secondary battery production device corresponding to the received gaze direction and gaze position based on an area on the display of the HMD (110). Here, the HMD (110) may be a display device worn on the head and may include various components such as, for example, one or more camera sensors, a gyroscope sensor, an accelerometer sensor, a microphone, a speaker, a button using a touch panel, an input / output port, and a vibrator for vibration. That is, the HMD (110) may estimate the user’s head movement and / or gaze direction using such various sensors, or estimate the user’s gaze position and gaze depth using a camera sensor that tracks the user’s eye movement. Additionally, the content associated with the secondary battery production device may refer to content that implements an actual secondary battery production plant and / or facility in virtual reality. That is, the user may be provided with a sensation similar to performing work in an actual secondary battery production plant through the content output through the HMD (110). Additionally, content related to the secondary battery production device according to the user's head movement and / or gaze direction may be output or displayed together on a separate monitor (130).

[0061] According to one embodiment, the simulation device can acquire user behavior information representing a user's motion determined from a controller (120) associated with an HMD (110), and can execute content associated with a secondary battery production device based on the acquired user behavior information. Here, the controller (120) may include various components such as a gyroscope sensor, an accelerometer sensor, a button using a touch panel, an input / output port, and a vibrator for vibration to track and reflect the hand movements, shapes, etc. of a user using content associated with a VR-based secondary battery production device, but is not limited thereto. That is, the controller (120) can estimate the user's motion using these various sensors, and the simulation device can acquire user behavior information representing the user's motion and execute content associated with a secondary battery production device, such as by operating a VR-based secondary battery production device.

[0062] According to one embodiment, a user can train or learn methods for operating a secondary battery production device, methods for dealing with defects, etc., by using VR-based content associated with a secondary battery production device. For example, when a simulation device receives input from a user to set and / or change condition values ​​of at least some of a plurality of adjustment parameters (e.g., a plurality of adjustment parameters included in the equipment operation part within the content) for operating a virtual secondary battery production device, or receives input to set and / or change the setting values ​​of the virtual secondary battery production device by performing physical measures on the virtual secondary battery production device, the simulation device may operate the virtual secondary battery production device according to the corresponding condition values ​​and / or setting values. That is, the simulation device may correct the operation of the virtual secondary battery production device, etc., according to the condition values ​​and / or setting values, and may modify the material (e.g., mono cell, etc.) and / or quality information of the material (e.g., quality information included in the quality verification part within the content) generated according to the corrected operation.

[0063] According to one embodiment, the simulation device determines one or more quality parameters for determining the quality of a material produced by a virtual secondary battery production device, and while the operation of the virtual secondary battery production device is being executed, it can calculate a value corresponding to each of the one or more quality parameters determined based on the operation of the virtual secondary battery production device being executed. Then, the simulation device can generate and display quality information related to the quality of the material produced by the virtual secondary battery production device based on the value corresponding to each of the one or more quality parameters calculated. That is, the user can correct the operation of the virtual secondary battery production device by changing the condition values ​​of at least some of the multiple adjustment parameters or by changing the setting values, and in this case, the simulation device can adaptively calculate and display quality information according to the corrected operation of the virtual secondary battery production device.

[0064] Although FIG. 1 illustrates a single user using the simulation device, it is not limited thereto, and multiple users may use the simulation device simultaneously. With such a configuration, a user performing secondary battery production can perform training related to the operation method of the secondary battery production device and the method of dealing with defects through the simulation device before being put into work. By training the user in this way, losses due to defects are significantly reduced, and the efficiency of the secondary battery production work can be effectively improved.

[0065] FIG. 2 is a functional block diagram showing the internal configuration of a simulation device (200) according to an embodiment of the present invention. As illustrated, the simulation device (200) may include, but is not limited to, a scenario management unit (210), a test execution unit (220), a user management unit (230), etc. The simulation device (200) may communicate with an HMD (110), a controller (120), a monitor (130), etc., and may exchange data and / or information related to VR-based content.

[0066] According to one embodiment, the scenario management unit (210) determines one or more training scenarios among a plurality of training scenarios associated with a secondary battery production device and can change content associated with the secondary battery production device based on the determined one or more training scenarios. For example, if the secondary battery production device is an L&S device, the plurality of training scenarios may include an electrode replacement scenario, a separator replacement scenario, a stacking tape replacement scenario, a quality check scenario, a sorting scenario, a wire breakage response scenario, etc. In this case, the scenario management unit (210) determines a training scenario by extracting at least one of the electrode replacement scenario, the separator replacement scenario, the stacking tape replacement scenario, the quality check scenario, the sorting scenario, and the wire breakage response scenario, and can change the adjustment parameters, operation, quality information, etc. of the virtual secondary battery production device according to the extracted or determined training scenario.

[0067] According to one embodiment, when a training scenario occurs, the user may change adjustment parameters or change the settings of a virtual secondary battery production device to resolve the generated training scenario. In this case, the scenario management unit (210) receives user behavior information for resolving one or more determined training scenarios and can correct the operation of the virtual secondary battery production device that has been changed based on the received user behavior information. Additionally, while the operation of the corrected virtual secondary battery production device is being executed, the scenario management unit (210) can calculate a value corresponding to each of a plurality of quality parameters associated with the quality of the material produced by the virtual secondary battery production device based on the operation of the virtual secondary battery production device being executed, and correct quality information associated with the quality of the material produced by the corrected virtual secondary battery production device based on the value corresponding to each of the calculated plurality of quality parameters.

[0068] According to one embodiment, the scenario management unit (210) may determine that a training scenario is resolved when a user performs actions corresponding to each training scenario in a predetermined order with an accuracy greater than a predetermined standard. For example, when a separator replacement scenario occurs, the user may perform actions in sequence such as i) checking the location of the unwinder with the depleted separator on the HMI (human machine interface) associated with the secondary battery production device, ii) removing the depleted separator, and iii) inserting a new separator and then operating the HMI to prepare for the next auto splice. In this case, the scenario management unit (210) may determine whether the training scenario is resolved based on user behavior information, such as whether a series of actions were performed in a predetermined order and whether cutting, etc., were performed with high accuracy.

[0069] Additionally or alternatively, the scenario management unit (210) may determine whether one or more training scenarios have been resolved using corrected quality information associated with a virtual secondary battery production device. For example, if the quality of the material is within a predetermined normal range, the scenario management unit (210) may determine that the training scenario has been resolved, but is not limited thereto; if the value of each quality parameter included in the quality information corresponds to a predetermined normal range or a specific value, the scenario management unit (210) may determine that the training scenario has been resolved. Additionally or alternatively, if the value calculated by providing each quality parameter to an arbitrary algorithm corresponds to a predetermined normal range, the scenario management unit (210) may determine that the training scenario has been resolved.

[0070] According to one embodiment, the scenario management unit (210) determines one or more defect scenarios among a plurality of defect scenarios associated with a secondary battery production device, and may change content associated with the secondary battery production device based on the determined one or more defect scenarios. For example, if the virtual secondary battery production device is an L&S device, the defect scenarios may include, but are not limited to, an x-axis alignment defect scenario, a y-axis alignment defect scenario, a cutting defect scenario, etc. associated with a mono cell generated by the L&S device. In this case, the scenario management unit (210) may determine a defect scenario by extracting at least one of the associated x-axis alignment defect scenario, y-axis alignment defect scenario, and cutting defect scenario, and may change the adjustment parameters, operation, quality information, etc. of the virtual secondary battery production device according to the extracted or determined defect scenario.

[0071] According to one embodiment, the setting values, condition values, etc. of a virtual secondary battery production device that are changed to the range of malfunction by a failure scenario may be predetermined for each failure scenario, but are not limited thereto. For example, a failure scenario may be generated based on error information that occurs when an actual secondary battery production device malfunctions. That is, when a malfunction occurs in an external device (e.g., an actual secondary battery production device) associated with the virtual secondary battery production device, the scenario management unit (210) may acquire error information associated with the malfunction and generate a failure scenario associated with the malfunction of the virtual secondary battery production device based on the acquired error information. For example, when a malfunction occurs in an L&S device, the scenario management unit (210) may acquire the values ​​of each adjustment parameter and the setting values ​​of the L&S device at the time of the malfunction as error information. The scenario management unit (210) may generate a failure scenario by changing the values ​​of each adjustment parameter and the setting values ​​of the device acquired in this way to correspond to the virtual secondary battery production device. With this configuration, a failure scenario is generated based on error information from the actual device, so the simulation device (200) can effectively generate training content optimized for the actual work environment.

[0072] According to one embodiment, the test execution unit (220) determines whether one or more training scenarios (or one or more defective scenarios) have been resolved, and if it is determined that one or more training scenarios have been resolved, it can calculate the execution time of one or more training scenarios, the value of the error procedure converted into a score, etc., while the one or more training scenarios are being executed. For example, the execution time for each training item can be converted into a score by comparing it with the standard time, and the value can be calculated through a predetermined arbitrary algorithm based on the number of error procedures converted into a score by comparing it with the existing correct procedure. In addition, the test execution unit (220) can generate operational capability information for a virtual secondary battery production device of a user account by verifying the calculated execution time and error procedure. Here, the user account may refer to the account of a worker using the simulation device (200), and the operational capability information is information indicating the work proficiency of the user, and may include work speed, evaluation score, etc. Additionally, the test execution unit (220) may determine whether the user has passed the simulation training based on operational capability information for each training scenario if the user has solved all predetermined types of training scenarios.

[0073] The user management unit (230) can perform management such as registration, modification, and deletion of user accounts associated with a user using the simulation device (200). According to one embodiment, the user can use the simulation device (200) using their registered user account. In this case, the user management unit (230) can store and manage information on whether each training scenario (or bad scenario) for each user account has been resolved, and information on operational capability corresponding to each training scenario, in an arbitrary database. Using the information stored by the user management unit (230), the scenario management unit (210) can extract information associated with a specific user account stored in the database and extract or determine at least one scenario among a plurality of training scenarios based on the extracted information. For example, the scenario management unit (210) may extract and generate or provide only training scenarios where the work speed is lower than the average work speed based on the information associated with the user account, but is not limited thereto, and training scenarios may be extracted or determined by other arbitrary criteria or a combination of arbitrary criteria.

[0074] In FIG. 2, each functional component included in the simulation device (200) is described separately, but this is merely to aid in understanding the invention, and one computational device may perform two or more functions. With such a configuration, the simulation device (200) can generate and provide to the user training scenarios and / or failure scenarios having various values ​​related to the secondary battery production device, and accordingly, the user can effectively learn countermeasures for each failure situation by training on how to operate the device or by resolving failure situations that may occur in the actual device on their own.

[0075] FIG. 3 is a diagram illustrating an example in which a simulation device (200) according to an embodiment of the present invention extracts a training scenario (312) and provides content (322). As described above, the simulation device (200) can determine one or more training scenarios (312) among a plurality of training scenarios associated with a secondary battery production device, and can change the content (322) associated with the secondary battery production device based on the determined one or more training scenarios (312). As illustrated, the simulation device (200) can extract one or more training scenarios (312) from a training scenario DB (310) and provide content (322) corresponding to the extracted training scenario (312) to an HMD (320).

[0076] According to one embodiment, a plurality of training scenarios may include an electrode replacement scenario associated with a secondary battery production device (e.g., an L&S device). When the electrode replacement scenario is determined as a training scenario, the simulation device (200) may determine one or more electrode supply units among a plurality of electrode supply units associated with the secondary battery production device for which electrode replacement is required, and create or change content. When the electrode replacement scenario occurs, the user may move to the determined electrode supply unit unwinder and operate or set the corresponding electrode supply unit using an HMI, etc. associated with the virtual secondary battery production device. For example, the user may stop the operation of the electrode supply unit by manually selecting the virtual HMI, etc. Then, the user may prepare for an auto splice by performing actions such as cutting the electrode and attaching a connecting tape.

[0077] In this case, the simulation device may acquire first user action information by operating one or more determined electrode supply units, cutting and connecting electrodes associated with one or more electrode supply units, and determine whether the electrode replacement scenario has been completed based on the acquired first user action information. For example, the simulation device may determine that the electrode replacement scenario is completed if the user cuts electrodes in a predetermined order at one or more determined electrode supply units and attaches connecting tapes. In this case, cutting accuracy, connection accuracy, etc., may be calculated or determined.

[0078] Additionally or alternatively, multiple training scenarios may include a separator replacement scenario associated with a secondary battery production device. When a separator replacement scenario is determined as a training scenario, the simulation device (200) may determine one or more separator supply units among the multiple separator supply units associated with the secondary battery production device for which separator replacement is required, and create or modify content. When a separator replacement scenario occurs, the user may move to the determined separator supply unit unwinder and operate or set the corresponding separator supply unit using an HMI, etc. associated with a virtual secondary battery production device. For example, the user may perform actions such as discarding the depleted separator after the auto-splice is completed, inserting a new separator, and manually operating the virtual HMI, etc. to prepare for the next separator auto-splice. Then, the user may perform actions such as cutting the separator and attaching a connecting tape, and restarting the separator supply unit to remove the depleted separator.

[0079] The simulation device can acquire second user action information by operating one or more determined membrane supply units, discarding depleted membranes associated with one or more membrane supply units, inserting a new membrane, and operating an HMI to prepare for an auto splice, and can determine whether the membrane replacement scenario is completed based on the acquired second user action information. For example, the simulation device can determine that the membrane replacement scenario is completed if the user performs the action of discarding depleted membranes in a predetermined order from one or more determined membrane supply units, inserting a new membrane, and manually operating a virtual HMI, etc., to prepare for the next membrane auto splice. In this case, cutting accuracy, connection accuracy, etc., may be calculated or determined.

[0080] Additionally or alternatively, multiple training scenarios may include a stacking tape replacement scenario associated with a secondary battery production device. When the stacking tape replacement scenario is determined as a training scenario, the simulation device (200) may determine one or more tape supply units among the multiple tape supply units associated with the secondary battery production device that require tape replacement, and create or change content. When the stacking tape replacement scenario occurs, the user may move to the determined tape supply unit and operate or configure the tape supply unit using an HMI, etc. associated with the virtual secondary battery production device. For example, the user may stop the operation of the tape supply unit by touching and selecting the virtual HMI, etc. Then, the user may perform the operation of removing the depleted tape from the tape supply unit and inserting a new tape, and the operation of restarting the equipment after checking the cutting quality by operating the HMI.

[0081] The simulation device can acquire third user action information regarding the operation of one or more determined tape feeders, the removal of an exhausted tape from one or more tape feeders, and the insertion of a new tape, and determine whether the stacking tape replacement scenario is completed based on the acquired third user action information. For example, the simulation device can determine that the stacking tape replacement scenario is completed if the user removes a tape from one or more determined tape feeders in a predetermined order and inserts a new tape, and then performs the action of reading the tape and the action of restarting the tape feeders via the HMI.

[0082] Additionally or alternatively, multiple training scenarios may include quality verification scenarios for materials (e.g., mono cells, stack cells, etc.) produced by the secondary battery production device. When a quality verification scenario is determined as a training scenario, the user can determine at least some of the dimensions, cutting condition, and sealing condition of the material produced by the secondary battery production device. For example, the user can take a sample from the mono cell vision inspection unit and check the dimensions, surface, cutting condition, sealing condition, etc. of the mono cell using a loupe tool, etc. In another example, the user can take a sample from the stack cell appearance inspection unit and check tabs, tapes, separators, electrode protrusions, etc. of the appearance. In this case, the user can input the dimensions, condition, etc. of the checked material through a separate input window, etc.

[0083] The simulation device acquires fourth user behavior information that determines at least some of the dimensions, cutting state, and sealing state of a material produced by a secondary battery production device, and can determine whether a quality verification scenario has been completed based on the acquired fourth user behavior information. For example, the simulation device can determine whether a quality verification scenario has been completed based on whether the user checks the surfaces of mono cells, stack cells, etc., in a predetermined order, whether a predetermined specific tool is used, and the accuracy of input values, states, etc.

[0084] Additionally or alternatively, multiple training scenarios may include a sorting scenario for sorting out defective materials. When the sorting scenario is determined as a training scenario, the user can determine whether each mono-cell generated by the secondary battery production device is defective. For example, the user may perform actions such as removing tape from a stacked cell generated by the secondary battery production device to extract a mono-cell, measuring the insulation resistance of the extracted mono-cell, determining whether the mono-cell is defective based on the gap between the electrode and the separator and the shoulder line defects, and reintroducing good products into the stacking equipment. In this case, the user can determine whether the measured insulation resistance and defect status of each mono-cell are defective by comparing them with the work standard document within the simulator.

[0085] The simulation device can extract a mono cell from a stack cell generated by a secondary battery production device, measure the insulation resistance of the extracted mono cell, perform an electrode surface condition inspection, and obtain fifth user action information that measures whether there is a gap between the electrode and the separator and whether there is a shoulder line defect, and determine whether the sorting scenario is completed based on the obtained fifth user action information. For example, the simulation device can determine that the sorting scenario is completed when the user performs actions such as extracting a mono cell in a predetermined order, measuring the insulation resistance of the extracted mono cell, performing an electrode surface condition inspection, measuring whether there is a gap between the electrode and the separator and whether there is a shoulder line defect, and determining whether there is a defect in the mono cell based on the measured values.

[0086] Additionally or alternatively, multiple training scenarios may include a disconnection response scenario. If the disconnection response scenario is determined as a training scenario, the simulation device can determine the disconnection location associated with a virtual secondary battery production device. In this case, the user may perform actions such as verifying the disconnection location (e.g., joining section, path-line, cutter section, etc.) by checking the HMI, operating the virtual secondary battery production device to remove the disconnected electrode, reading a new electrode to reconnect it, checking the electrode cutting status to determine if there is an abnormality, and restarting the equipment.

[0087] The simulation device acquires sixth user action information, which involves removing a disconnected electrode at a determined disconnection location and connecting a new electrode, and can determine whether the disconnection action scenario is completed based on the acquired sixth user action information. For example, the simulation device can determine that the disconnection action scenario is completed if the user performs actions such as removing a disconnected electrode and connecting a new electrode in a predetermined order.

[0088] In FIG. 3, it is described that a single training scenario occurs and is processed by the user, but this is not limited thereto, and multiple training scenarios may occur simultaneously in combination. With such a configuration, the user can perform the necessary training in advance to operate or run a secondary battery production device using a virtual VR-based simulation device, and accordingly, when the new worker is introduced into the actual production process, the loss that may occur can be significantly reduced.

[0089] FIG. 4 is a diagram showing an example in which operational capability information (420) and test results (430) are generated according to an embodiment of the present invention. As described above, when a training scenario (or a bad scenario) occurs, the simulation device (200) receives user behavior information (410), etc. from a user (an HMD, controller, etc. associated with the user), and can determine whether the training scenario has been resolved based on the received user behavior information (410), etc.

[0090] According to one embodiment, when the simulation device (200) determines that the training scenario has been resolved, it calculates the execution time and error procedure conversion value of the training scenario during the execution of the training scenario, and generates operational capability information (420) for a virtual secondary battery production device of a user account based on the calculated execution time and error procedure conversion value. Here, the user's training score may be calculated using an arbitrary algorithm based on the user's sequence of operations, operation accuracy, etc., but is not limited thereto.

[0091] According to one embodiment, test results (430) may be output along with operational capability information (420). For example, a user associated with the corresponding user account may perform a test for any training scenario, and if all training scenarios associated with a specific secondary battery production device are solved according to predetermined criteria, the simulation device (200) may determine that the user has passed the simulation test for the secondary battery production device.

[0092] FIG. 5 is a diagram showing an example of a display screen (500) on which VR-based content is displayed according to an embodiment of the present invention. As described above, content related to a secondary battery production device corresponding to the user's gaze direction and gaze position may be displayed on the display screen (500) of the HMD. In this case, the content may also be displayed together on any display device (e.g., a monitor) associated with the HMD.

[0093] According to one embodiment, the content may include VR videos, animations, etc., implemented in virtual reality of a factory, facility, etc., including a secondary battery production device. In the illustrated example, the content may include images, etc., representing user hand movements sensed using a controller and an HMI (e.g., facility operating part) (510) that includes a plurality of adjustment parameters capable of determining or adjusting the operation of a secondary battery production device (e.g., L&S device). The user can experience a virtual secondary battery production facility using a VR device composed of an HMD and a controller.

[0094] According to one embodiment, a user can execute or change the operation of a secondary battery production device by changing or adjusting the condition values ​​of at least some of the multiple adjustment parameters included in the HMI (510). For example, the user can execute or change the operation of the secondary battery production device by selecting an area corresponding to an icon, etc., that can change the condition values ​​of at least some of the multiple adjustment parameters, using touch input (520), etc. That is, the operation of the virtual secondary battery production device can be adaptively changed or corrected by changes in the adjustment parameters input by the user.

[0095] According to one embodiment, the simulation device may change the operation of a virtual secondary battery production device or change quality information generated by the changed operation of the virtual secondary battery production device based on each condition value of the adjustment parameter entered by the user. Additionally or alternatively, the user may change the setting value of the virtual secondary battery production device by performing physical actions such as touching or dragging the virtual secondary battery production device. In this case, the simulation device may change the operation of the virtual secondary battery production device or change quality information generated by the changed operation of the virtual secondary battery production device based on the setting value changed by the user.

[0096] FIG. 6 is a diagram showing an example of a display screen (600) on which user guide information (610) according to an embodiment of the present invention is displayed. As described above, content related to a secondary battery production device corresponding to the user's gaze direction and gaze position may be displayed on the display screen (600) of the HMD. In this case, the content may also be displayed together on any display device (e.g., a monitor) associated with the HMD.

[0097] As described, when a disconnection scenario occurs, the user can perform the action of removing the disconnected electrode at the disconnection location and connecting a new electrode. For example, the user can select a cutter knife tool via touch input or the like, and then use the tool to remove the disconnected electrode and connect a new electrode. In this case, user guide information (610) to guide the user on the necessary actions and / or a line (620) for removing the electrode, etc., may be displayed on the display screen (600).

[0098] According to one embodiment, the simulation device can determine whether the user satisfies the guide condition based on the user's gaze direction and gaze position. For example, the simulation device may determine that the guide condition is satisfied if the user is within a predetermined distance of a disconnection position associated with the disconnected electrode, but is not limited thereto. In another example, the simulation device may determine that the guide condition is satisfied if the user gazes at the disconnection position for a predetermined period of time.

[0099] If it is determined that the user satisfies the guide conditions, the simulation device may display user guide information (610) associated with one or more determined training scenarios along with content associated with the secondary battery production device. In the illustrated example, the user guide information (610) may include a guidance message such as, "Use a utility knife to cut the severed electrode end in a straight line along the indicated dotted line." With this configuration, the user can effectively perform training using the user guide information (610) even if they do not know how to respond to the training scenario.

[0100] FIG. 7 is a diagram showing an example of a display screen (700) in which operational capability information (710) according to an embodiment of the present invention is displayed. As described above, content related to a secondary battery production device corresponding to the user's gaze direction and gaze position may be displayed on the display screen (700) of the HMD. In this case, the content may also be displayed together on any display device (e.g., a monitor) associated with the HMD.

[0101] According to one embodiment, the simulation device determines whether at least some of a plurality of training scenarios associated with a secondary battery production device have been completed by a user, and if it is determined that at least some of the plurality of training scenarios have been completed, it can calculate user operational capability information (710) corresponding to at least some of the completed plurality of training scenarios. In this case, the calculated user operational capability information (710) may be displayed together with content associated with the secondary battery production device, but is not limited thereto.

[0102] In the illustrated example, operational capability information (710) may include the time taken, procedure results, misoperation procedures, and evaluation scores. For example, each training scenario may consist of multiple procedures, and the simulation device may determine whether the user performs the multiple procedures in a predetermined order with an accuracy greater than a predetermined standard. If the user performs the procedures out of order or with an accuracy lower than a predetermined standard, the simulation device may determine that the procedure is a misoperation procedure. Then, the simulation device may calculate and provide an evaluation score for the user's specific training scenario using the total time taken, the number of misoperation procedures, etc. With this configuration, the user can simply identify and process training scenarios that are lacking in training, thereby allowing them to focus on training only the training scenarios with low work proficiency.

[0103] FIG. 8 is a diagram showing an example of how a defect scenario (822) is generated according to an embodiment of the present invention. As illustrated, the simulation device (200) communicates with an external device (e.g., a secondary battery production device, etc.) (810), a defect scenario DB (820), etc., and can exchange data and / or information necessary for generating the defect scenario (822).

[0104] According to one embodiment, if a malfunction occurs in an external device (810), the simulation device (200) may receive or obtain error information (812) associated with the malfunction that occurred from the external device (810). Here, the error information (812) may include operation information of the external device (810) at the time the malfunction occurred and the amount of change in quality of the material generated by the external device (810). In this case, the simulation device (200) may determine the values ​​of each quality parameter of the condition value, setting value, and / or quality information of a virtual secondary battery production device to correspond to the error information (812), and may generate a defect scenario (822) having the determined values ​​of the condition value, setting value, and / or quality parameter of the virtual secondary battery production device. The defect scenario (822) thus generated may be stored and managed in a defect scenario DB (820). For example, the simulation device (200) can generate a defect scenario (822) by using any algorithm and / or a learned machine learning model to determine the value of each quality parameter of the condition value, setting value and / or quality information of a virtual secondary battery production device to correspond to error information (812).

[0105] According to one embodiment, the simulation device (200) can convert operation information of an external device (810) into a first set of parameters associated with the operation of a virtual secondary battery production device, and convert the amount of change in quality of a material generated by the external device (810) into a second set of parameters associated with quality information associated with the quality of a material generated by the virtual secondary battery production device. Then, the simulation device (200) can determine the category of a malfunction that occurred in the external device (810) using the converted first set of parameters and the second set of parameters, and generate a defect scenario based on the determined category, the first set of parameters, and the second set of parameters.

[0106] In FIG. 8, it is described that a failure scenario is generated when an external device (810) malfunctions, but this is not limited thereto, and for example, the failure scenario can be predetermined by any user. In another example, the failure scenario may be generated by randomly determining setting values, condition values, quality information, etc. associated with a virtual secondary battery production device within a predetermined abnormal range. With such a configuration, the user can effectively improve their ability to respond to failures by training using a failure scenario generated based on a malfunction that occurred in an actual work environment.

[0107] FIG. 9 is a diagram illustrating an example of a VR-based simulation method (900) for producing a secondary battery according to an embodiment of the present invention. The VR-based simulation method (900) for producing a secondary battery may be performed by a processor (e.g., at least one processor of a simulation device). As illustrated, the VR-based simulation method (900) for producing a secondary battery may be initiated by the processor receiving the user's gaze direction and gaze position identified from the HMD (S910).

[0108] The processor can display content associated with a secondary battery production device corresponding to the received gaze direction and gaze position based on the area on the display of the HMD (S920). In this case, the content can be displayed together on any monitor (display device) associated with the HMD.

[0109] The processor can obtain user behavior information representing a user motion determined from at least one of the HMD and the controller associated with the HMD (S930). Additionally, the processor can execute content associated with the secondary battery production device based on the obtained user behavior information (S940). According to one embodiment, the processor determines one or more training scenarios among a plurality of training scenarios associated with the secondary battery production device, and can change content associated with the secondary battery production device based on the determined one or more training scenarios.

[0110] FIG. 10 is a diagram illustrating an example of a test result calculation method (1000) according to one embodiment. The test result calculation method (1000) may be performed by a processor (e.g., at least one processor of a simulation device). As illustrated, the test result calculation method (1000) may have a processor determine whether at least some of a plurality of training scenarios associated with a secondary battery production device have been completed by a user (S1010).

[0111] When the processor determines that at least some of the multiple training scenarios have been completed, it can calculate user operation capability information corresponding to at least some of the completed multiple training scenarios (S1020). Additionally, the processor can display the calculated user operation capability information together with content associated with the secondary battery production device (S1030). For example, the processor can calculate operation capability information, etc. by inputting the user's operation sequence, operation accuracy, response time, etc., into any algorithm, machine learning model, etc., but is not limited thereto.

[0112] FIG. 11 is a diagram illustrating an example of a method for generating a failure scenario (1100) according to an embodiment of the present invention. The method for generating a failure scenario (1100) may be performed by a processor (e.g., at least one processor of a simulation device). As illustrated, the method for generating a failure scenario (1100) may be initiated by the processor obtaining error information associated with a malfunction when a malfunction occurs in an external device associated with a virtual secondary battery production device (S1110).

[0113] The processor can generate a failure scenario associated with a malfunction of a virtual secondary battery production device based on acquired error information (S1120). Here, the error information may include the values ​​and setting values ​​of each adjustment parameter of the production equipment in the event that the actual secondary battery production equipment associated with the virtual secondary battery production device malfunctions. For example, if the quality of the material produced by the secondary battery production equipment deviates from a predetermined normal range, it may be determined that a malfunction has occurred. If it is determined that a malfunction has occurred, the processor acquires error information associated with the malfunction and can generate a failure scenario associated with a malfunction of the virtual secondary battery production device based on the acquired error information.

[0114] FIG. 12 illustrates an exemplary computing device (1200) for performing the method and / or embodiment described above. According to one embodiment, the computing device (1200) may be implemented using hardware and / or software configured to interact with a user. Here, the computing device (1200) may include the simulation device (200 of FIG. 2) described above. For example, the computing device (1200) may be configured to support a virtual reality (VR), augmented reality (AR), or mixed reality (MR) environment, but is not limited thereto. The computing device (1200) may include, but is not limited to, a laptop, desktop, workstation, personal digital assistant, server, blade server, mainframe, etc. The components of the computing device (1200) described above, their connections, and their functions are intended to be exemplary and are not intended to limit the embodiments of the invention described and / or claimed herein.

[0115] The computing device (1200) includes a processor (1210), memory (1220), storage device (1230), communication device (1240), a high-speed interface (1250) connected to the memory (1220) and a high-speed expansion port, and a low-speed interface (1260) connected to the low-speed bus and storage device. Each of the components (1210, 1220, 1230, 1240 and 1250) may be interconnected using various buses and may be mounted on the same main board or connected in other suitable ways. The processor (1210) may be configured to process instructions of a computer program by performing basic arithmetic, logic, and input / output operations.
