Description

Battery cell assembly process simulation system

[0001] This application claims the benefit of priority from Republic of Korea Patent Application No. 10-2024-0086449, dated July 1, 2024, the entire contents of which are incorporated herein by reference.

[0002] The present invention relates to a battery cell assembly process simulation system, and more particularly, to a battery cell assembly process simulation system that can provide efficient training to new workers on actual process equipment without affecting the operation of actual process equipment.

[0003] As demand for secondary batteries surges, the capacity and operating hours of secondary battery production facilities are increasing. While significant automation has been achieved in production facilities, human-based management remains essential. Consequently, new personnel are constantly being added to these expanded facilities. Given this trend of facility expansion and increased operating hours to meet product demand, providing training based on actual equipment performance inevitably limits operating hours, thus undermining the very purpose of facility expansion to meet product demand.

[0004] Accordingly, simulation systems are being developed to simulate equipment in virtual reality to a degree that rivals real-world equipment and to train workers. These simulation systems virtually replicate the entire equipment required to produce a given product. These simulation systems are beneficial because they do not interfere with the operation of the actual equipment.

[0005] However, conventional simulation systems, which consist of uniform training scenarios, fail to reflect the individual characteristics of the workers participating in the training. For example, training workers who are new to the target equipment and those who already have experience with similar equipment using the same training scenario is inefficient from a human resource utilization perspective.

[0006] Furthermore, because there is a lot of content to be taught in a uniform training scenario, even when workers who have received such training are assigned to management tasks in actual production facilities, the rate of improvement in their job skills is slower than when they were trained in actual process facilities.

[0007] The present invention has been devised to solve the above-described problems, and aims to provide a battery cell assembly process simulation system that improves training efficiency by providing a training scenario that reflects the individual characteristics of workers.

[0008] The present invention aims to provide a battery cell assembly process simulation system capable of producing results similar to those of apprenticeship training in an actual process facility.

[0009] The technical objectives of the present invention are not limited to the purposes mentioned above. Other objectives and advantages of the present invention not mentioned above can be understood through the following description and will be more clearly understood through the embodiments of the present invention. Furthermore, it will be readily apparent that the objectives and advantages of the present invention can be realized by the means and combinations thereof set forth in the claims.

[0010] The battery cell assembly process simulation system of the present invention, which addresses the aforementioned challenges, can be used to provide process training to workers involved in the assembly process of cylindrical can-shaped battery cells. However, the product types are not limited thereto.

[0011] The above battery cell assembly process simulation system includes a server in which basic information and training information about training facilities, which are battery cell process facilities that are the subject of training, are stored, and work histories of workers participating in the training are stored.

[0015] The training information of the above training facility may include new training information assuming that the training facility is a new facility and changed training information assuming that the training facility is a facility that has been partially changed from an existing facility.

[0016] The worker's work history stored in the above server may include experience information regarding whether or not the worker has experience with the existing equipment.

[0017] The above training information may include at least one of a description of the process performed by the training facility, a description of the facility structure, a description of the facility operation method, a description of quality assurance, and information on the implementation of condition changes of the facility.

[0018] The above training information may include information on three-dimensionally modeling the training facility to correspond to actual facilities and implementing motion to correspond to the operation of the actual facilities.

[0019] The above battery cell assembly process simulation system includes a terminal that provides training information to workers participating in training, and an input interface provided on the terminal to input information of workers participating in training.

[0020] The above terminal may include a display that allows the worker to visually check the training information and an audio device that allows the worker to audibly check the training information.

[0021] The above input interface may include a character input interface, a voice input interface, a body authentication information input interface, etc. The body authentication information may include fingerprint, facial, or voice information.

[0022] The above battery cell assembly process simulation system may include an educational content selection logic that extracts the work history of a worker corresponding to the input worker information and constructs a training curriculum to be provided to the terminal based on the extracted work history.

[0023] The above selection logic may be a software program. The above selection logic may be executed on the server or on the terminal.

[0024] In a partial embodiment, a training curriculum is built on a server, and the server can provide training information corresponding to the built curriculum to the terminal.

[0025] In a partial embodiment, a training curriculum is built in a terminal, the terminal requests training information corresponding to the built curriculum from a server, and the server can provide the requested training information to the terminal.

[0026] The above training content selection logic can provide changed training information as training information for training facilities that have been partially changed from the existing facilities, if it is confirmed based on the experience information of the training participant that the worker has experience with existing facilities.

[0027] The above training information may include a description of product factors that must be managed in the training facility, a description of what happens when the product factors go out of the management scope, and a description of how to manage the product factors.

[0028] The above educational information may include information about outcomes where the product recognition is outside the scope of management.

[0029] The method for operating the above simulation system includes a step of receiving information about a worker, a step of extracting the worker's work history corresponding to the received information, a step of constructing a training curriculum by selecting training information for training facilities based on the extracted work history, and a step of providing the constructed training curriculum to the worker's training terminal.

[0030] Worker information can be entered through the terminal's input interface. The entered worker information can be transmitted to the server.

[0031] The server can extract the work history of the worker corresponding to the received information.

[0032] In a partial embodiment, the server can build a training curriculum based on the extracted work history. The training curriculum can be built by selecting appropriate training information based on the worker's work history from training information about training facilities stored on the server. The server can provide training information corresponding to the built training curriculum to the terminal.

[0033] In a partial embodiment, the server transmits the extracted work history of the worker to the terminal, and the terminal can construct a training curriculum based on the received work history. The training curriculum can be constructed by selecting appropriate training information based on the worker's work history from training information about training facilities stored on the server. The terminal can request training information corresponding to the constructed training curriculum from the server. The server can provide the requested training information to the terminal.

[0034] In the above training curriculum construction step, based on the work history of the worker, for a training facility that is identical to an existing facility among the training facilities and for which the worker has experience with the existing facility, a curriculum can be constructed that provides the worker with information that the training facility is identical to the existing facility and an opportunity to choose whether to complete training for the training facility.

[0035] In the above training curriculum construction step, the training curriculum can be constructed by selecting changed training information based on the worker's work history, for training facilities that have been partially changed from existing facilities and for which the worker has experience with the existing facilities, assuming that the training facilities are facilities that have been partially changed from existing facilities.

[0036] The above training curriculum can be constructed by selecting new training information based on the work history of the worker, assuming that the training facility is new, for a training facility that is identical to an existing facility or has been partially modified from an existing facility and for which the worker has no experience with the existing facility.

[0037] The above training curriculum can be constructed by selecting new training information based on the assumption that the training facility is new among new facilities.

[0038] Training information included in the constructed training curriculum may include a description of product factors that must be managed in the training facility, a description of what happens when the product factors go out of control, and a description of how to manage the product factors.

[0039] Additionally, the training information may include training procedures for workers to implement management methods to bring the product factor within the control range when the product factor is out of the control range.

[0040] Additionally, the above training information may include result data on whether the product factor came within the control range as a result of the worker implementing the management method and result data on the impact of the product processed as a result of the worker implementing the management method on other processes.

[0041] According to the battery cell assembly process simulation system and its operation method according to the present invention, worker training is possible without affecting the operation of actual equipment.

[0042] According to the present invention, it is possible to train workers in advance before the actual facility is constructed, so that the facility can be operated smoothly at the same time as the facility is constructed.

[0043] According to the present invention, customized training can be provided based on the worker's work experience, thereby shortening the worker's training period and increasing training efficiency.

[0044] According to the present invention, it is possible to enhance a worker's product factor management ability in advance, and to visually provide the worker with problems that may arise according to the training results, thereby achieving an educational effect equivalent to that of apprenticeship training through virtual training.

[0076] Hereinafter, a preferred embodiment of a battery cell assembly process simulation system and its operation method according to the present invention will be described in detail with reference to the attached drawings.

[0077] The above battery cell assembly process simulation system is used to provide training on the process to workers who perform the battery cell assembly process.

[0078] The battery cell that is the target of the assembly process exemplified in the embodiment may be a cylindrical battery cell (10) as illustrated in Fig. 1. The cylindrical battery cell (10) may have a form factor of, for example, 46800 or 46950.

[0079] In order to manufacture the above cylindrical battery cell (10), an electrode assembly (11) wound in a jelly-roll shape is supplied as illustrated in Fig. 2. At both axial ends of the electrode assembly (11), a non-coated portion, where no active material is applied to the current collectors of the two electrodes, is provided in a protruding and radially inwardly bent form.

[0080] As shown in Fig. 3, a positive electrode collector plate (12) and a negative electrode collector plate (13) are welded to each of the axial ends of the supplied electrode assembly (11).

[0081] As illustrated in Fig. 5, an insulator (16) is inserted into the can (15) of the cylindrical battery cell (10). In addition, a positive terminal (17) is riveted into a through hole provided in the axial end wall of the can (15) of the cylindrical battery cell (10) with a gasket interposed therebetween, as illustrated in Fig. 6.

[0082] Next, as illustrated in FIG. 7, a process of inserting the electrode assembly (11) into the can (15) is performed. The can (15) into which the electrode assembly (11) is inserted is inverted as illustrated in FIG. 8, and the side wall of the can (15) can be beaded. The edge of the negative electrode collector (13) is welded to the beaded portion (111) of the beaded can (15), and an electrolyte is injected into the interior of the can (15).

[0083] Next, as shown in Fig. 9, a gasket is inserted and the opening of the can (15) is covered with a vent cap (18), and the edge of the can (15) is crimped to form a crimped portion (112).

[0084] Equipment for performing a process for assembling the above cylindrical battery cell (10) includes an electrode assembly supply equipment for performing the process illustrated in FIG. 2, an electrode assembly and current collector plate welding equipment for performing the process illustrated in FIG. 3, an electrode assembly insulation taping equipment for performing the process illustrated in FIG. 4, an insulator insertion equipment for performing the process illustrated in FIG. 5, an electrode terminal riveting equipment for performing the process illustrated in FIG. 6, an electrode assembly insertion equipment for performing the process illustrated in FIG. 7, a can beading processing equipment for performing the process illustrated in FIG. 8, a current collector plate and beading welding equipment, an X-ray inspection equipment, an electrolyte injection equipment, a can crimping processing equipment for performing the process illustrated in FIG. 9, a cleaning equipment, a CT inspection equipment, an appearance inspection equipment, and a battery cell performance inspection equipment.

[0085] In response to this, the training facility constructed for the process facility that is the subject of training among the above assembly process facilities may include all of the above facilities or may selectively include facilities requiring training.

[0086] Referring to FIG. 10, the battery cell assembly process simulation system includes a server (20) in which information about the training facility is stored.

[0087] The server (20) may further store existing facility information regarding existing battery cell assembly process facilities. The existing battery cell may be a cylindrical battery cell having a form factor of 21700. In addition, the existing facilities corresponding thereto may include at least one of an electrode assembly supply facility, a lower insulator insertion facility for a can, an electrode assembly insertion facility for a can, an upper insulator insertion facility for a can, a can beading processing facility, an X-ray inspection facility, an electrolyte injection facility, an electrode tab welding facility, a can crimping processing facility, a cleaning facility, a marking facility, and a battery cell performance inspection facility.

[0088] Additionally, the existing battery cell assembly process equipment may further include an assembly process equipment for a cylindrical battery cell having a form factor of 18650.

[0089] Information about the above educational facilities includes basic information and educational information.

[0090] The above basic information includes whether the training facility is the same as an existing facility, whether it is a facility that has been partially modified from an existing facility, and whether it is a new facility.

[0091] For example, referring to FIG. 11, the training facility (b) may include five facilities, for example, A, B2, C2, F, and E, the existing facility (a) related to the 21700 battery cell may include five facilities, for example, A, B1, C1, D, and E, and the existing facility (c) related to the 18650 battery cell may include five facilities, for example, A1, B0, C2, D1, and E. In this case, the basic information about the above training facility (b) may mean that facility A is identical to existing facility (a) and is partially changed from existing facility (c), facility B2 is partially changed from existing facility (a) and is partially changed from existing facility (c), facility C2 is partially changed from existing facility (a) and is identical to existing facility (c), facility F is a new facility that did not exist before, and facility E is identical to existing facility (a) and is identical to existing facility (c).

[0092] Here, "identical" does not mean strictly consistent, but rather means that the content to be taught for this equipment is substantially identical to that taught for the existing equipment. Furthermore, "partially changed" means that some of the content to be taught for this equipment overlaps with that for the existing equipment, while others are new content not included in the existing training or can be explained by comparison with the existing training.

[0093] Training information for the same training facility may include different versions of the training information. For example, the different versions of the training information may include a new training information version based on the assumption that the training facility is new, and a modified training information version based on the assumption that the facility has undergone some modifications from the existing facility.

[0094] For example, referring to FIG. 11, the training information version for facility B2 among training facilities (b) may include a new training information version that assumes that facility B2 is a new facility, a changed training information version that focuses on the differences between facility B2 and facility B1 of the existing facility (a), and a changed training information version that focuses on the differences between facility B2 and facility B0 of the existing facility (c). The training information version for facility F among training facilities (b) may include a new training information version that assumes that facility F is a new facility. The training information version for facility E among training facilities (b) may include a new training information version that assumes that facility E is a new facility.

[0095] The server (20) stores information about workers participating in the training. This information can be continuously updated. The worker information includes the worker's work history. The worker's work history stored in the server includes information regarding his or her experience with the existing equipment.

[0096] For example, referring to FIG. 12, the work history information of worker 1 includes information that he has experience with 21700 battery cell assembly equipment, the work history information of worker 2 includes information that he has no experience with existing equipment, and the work history information of worker 3 includes information that he has experience with 18650 battery cell assembly equipment.

[0097] Referring to FIG. 10, the battery cell assembly process simulation system of the embodiment includes a terminal (30) that provides training information to a worker (J) participating in training. The worker (J) can virtually experience and acquire knowledge of the battery cell manufacturing process through interaction with the terminal (30).

[0098] The server (20) can manage training information provided to the worker (J) via the terminal (30). The server (20) stores training information performed by the worker (J) via the terminal (30), calculates statistical data based on the training information, adds or modifies training information based on the statistical data, and transmits the training information to the terminal (30). The server (20) can install or update training information management software on the terminal (30).

[0099] The terminal (30) is connected to the server (20) so that it can transmit and receive information via a known communication protocol. The terminal may include a display (31) that allows the worker (J) to visually check the training information, and an audio device (32, 33) that allows the worker (J) to audibly check the training information.

[0100] The terminal (30) includes an input interface through which a worker participating in training can input information. The input interface may include a character input interface (35) including a keyboard, mouse, touch panel, etc., a voice input interface (36) including a microphone, and a body authentication information input interface (37) including a camera and a fingerprint recognition device. The body authentication information may include fingerprint, facial, or voice information.

[0101] The worker (J) can input information about himself / herself through the input interface. Furthermore, the worker can interact with the terminal (30) through the input interface. The worker (J) generates operational inputs through touch input, button input, mouse input, voice input, etc., and the input interface can receive such operational inputs from the worker (J). The received operational inputs can be utilized for operating the terminal (30), selecting items, adjusting process conditions, etc.

[0102] The above terminal (30) may include a processor and memory for executing simulation software.

[0103] The processor may have a structure for executing instructions that implement the operations of the terminal (30). The processor may be implemented as an array of multiple logic gates for processing various operations or as a general-purpose microprocessor, and may be composed of a single processor or multiple processors. For example, the processor may be implemented in the form of at least one of a microprocessor, a CPU, a GPU, and an AP.

[0104] The memory or storage may be configured to temporarily store data or instructions, and may be configured separately from or integral with the processor. The processor may execute instructions stored in the memory and / or storage to perform various operations. The memory and / or storage may store various data, instructions, mobile applications, computer programs, etc. For example, the memory and / or storage may be implemented as a non-volatile device such as ROM, PROM, EPROM, EEPROM, flash memory, PRAM, MRAM, RRAM, FRAM, etc., or a volatile device such as DRAM, SRAM, SDRAM, PRAM, etc., and may be implemented in the form of an HDD, SSD, SD, Micro-SD, etc., or a combination thereof.

[0105] The display (31) can provide various visual information to the worker (J). The display (31) can display a simulation image of the training facility running on the terminal (30) as shown in FIGS. 13 to 16.

[0106] For example, when the assembly process of a cylindrical battery cell is virtually simulated at a terminal (30), an image of the appearance and operation of the corresponding process equipment that can be recognized with the naked eye can be displayed on the display (31) by simulating the actual equipment as illustrated in FIG. 13. In addition, the display (31) can also display an image of a non-visible area of ​​the corresponding process that cannot be recognized with the naked eye.

[0107] In addition, the above display (31) can output by simulating the equipment operation panel used in an actual manufacturing line as shown in Fig. 14, and the operation method can also be implemented in the same manner as the operation method of an actual equipment operation panel through an input interface.

[0108] In addition, the above display (31) displays an image simulating a vision and sensor measurement screen, a dimension measurement screen, etc. as shown in FIG. 15, and displays an image simulating a production execution system as shown in FIG. 16.

[0109] The terminal (30) provides the worker (J) with training information that reproduces the battery cell assembly process based on the operator's (J) operational input via the input interface. For example, a training simulation that identically reconstructs the actual assembly process of a cylindrical battery cell through the operational input is executed.

[0110] The terminal (30) can interact with the worker (J) and provide educational information to the worker (J). For example, for the can beading process, the worker (J) can experience educational information on the process of forming the crimping portion (112) through plastic processing of the can (15) as a virtual reality implemented as a three-dimensional image as shown in FIG. 13. At this time, the worker (J) can virtually experience the operation of the beading processing equipment by making an operation input through the input interface. Referring to FIG. 14, the display and the input interface can be implemented by simulating the operation panel of an actual beading processing equipment, and the input method and operation input can also be implemented so that input can correspond to the actual equipment.

[0111] The display (31) of the terminal (30) is configured to display detailed images based on the characteristics of the training information. For example, in the training information on quality inspection through dimensional measurement, detailed images regarding the dimensional measurement of the measurement target may be displayed on the display (31), as illustrated in FIG. 15. For example, in the training information on the execution of condition changes in equipment, images regarding the production execution system may be displayed on the display (31), as illustrated in FIG. 16.

[0112] Referring to Figure 13, the training information includes information on three-dimensionally modeling the training equipment to correspond to actual equipment and implementing motions to correspond to the operations of the actual equipment. The training information may be configured as a camera view corresponding to the worker's movement path and line of sight for equipment operation and inspection. This training information may include information on 17 process equipment and 7 material input equipment.

[0113] The above 3D modeling and motion are implemented not only for the equipment itself, but also for the products processed by the equipment. Accordingly, the above training information also includes information on changes in the product's shape as the process progresses. The above motion is implemented from the beginning to the end of the process.

[0114] Referring to Fig. 14, the above training information includes an MHI (human machine interface) for virtually implemented equipment operation. This includes image information for displaying an actual MHI on a display (31) as is, and information for implementing an input interface for operating and stopping the equipment, an input interface for manual operation of the equipment, and an input interface for sampling, all through the touch panel and software of the display (31).

[0115] Referring to Figure 15, the above training information includes information on vision and sensor measurement screens, dimension measurement screens, etc. This can be implemented by simulating actual vision and sensors.

[0116] Referring to Figure 16, the training information includes information regarding a manufacturing execution system (MES). This can be implemented as an image identical to the actual manufacturing execution system.

[0117] Training information for the above training facility includes a description of the process implemented by the facility, a description of the facility's structure, a description of the facility's operation method, a description of quality assurance, and information on implementing condition changes to the facility. Furthermore, the training information includes process and facility guidance information, including instructions for operating the facility, and virtual scenarios for training in operating the facility or performing quality assurance.

[0118] The above training information includes a level testing procedure for improving workers' job skills. The training information may include virtual scenarios for training in adjusting process conditions, virtual scenarios for training in identifying process defects, and virtual scenarios for training in responding to process defects.

[0119] The above training information includes at least one of guidance information for the assembly process of a cylindrical battery cell, equipment operation information, quality assurance information, and process condition adjustment information. The process guidance information describes the assembly processes of a cylindrical battery cell. Workers can virtually receive training on individual assembly processes and procedures through 3D simulation and motion. The equipment operation information includes information on the operation, maintenance, and management of process equipment required to perform the above assembly processes. The quality assurance information may include information for virtually experiencing the process of checking the quality of products that have completed each process.

[0120] Process condition adjustment information may include information for adjusting process conditions or process requirements required for assembly processes and checking changes in products that have completed the process in response thereto. The terminal (30) displays visual information on the display (31) showing changes in the process object according to the process being performed on the process object in response to the input of the worker (J). For example, the terminal (30) may receive input from the worker (J) through the input interface, change the assembly state of a virtual battery cell accordingly, and display the changed assembly state to the worker (J).

[0121] The above training information may include a description of product factors that must be managed in the training facility, a description of what happens when the product factors are out of the management scope, a description of how to manage the product factors, and information about the consequences of the product recognition being out of the management scope.

[0122] Additionally, the above training information may include a training procedure for a worker (J) to implement a management method to bring the product factor within the management range when the product factor is out of the management range.

[0123] Additionally, the above training information may include result data on whether the product factor came within the control range as a result of the worker (J) implementing the management method and result data on the impact of the product processed as a result of the worker implementing the management method on other processes.

[0124] For example, referring to FIG. 17, the training information explains the height (h) setting of the beading knife and the advance depth (d) of the beading knife as product factors in the beading section processing process. Subsequently, the training information displays the production execution system image of FIG. 16 to the user and prompts the user to input process conditions based on what they have learned from the explanation.

[0125] If the operator (J) inputs the correct first condition, the training information shows the result of the corresponding beading process corresponding to the input first condition and the result that has gone through the next crimping process, as shown in Fig. 18. Through this image, the operator (J) can confirm that the length of the crimping part is appropriate and that the crimping process has been performed as designed. On the other hand, if the operator (J) inputs the second condition that is out of the correct range, the training information shows the result of the corresponding beading process corresponding to the input second condition and the result that has gone through the next crimping process, as shown in Fig. 19. Through this image, the operator (J) can confirm that the length of the crimping part is insufficient and that a defect has occurred in the crimping part.

[0126] By visually examining these images, workers (J) gain an experiential understanding of the process conditions. In this way, the training information visually depicts how the process conditions entered by the user produce the results of the process, and how they impact subsequent processes. This allows users to connect the depicted product results with the process conditions, rather than simply memorizing the process conditions numerically. This allows for a level of educational effectiveness equivalent to that achieved through apprenticeship training in the field.

[0127] The terminal (30) may be configured to calculate the expected defect rate of the product based on the assembly quality for each process. The terminal (30) may select representative defect cases among the assembly processes based on the assembly quality and the expected defect rate, and provide the worker (J) with additional training scenarios for these cases. For example, the terminal (30) may provide the worker (J) with additional training information on process facilities where defects frequently occur based on the results of process condition adjustments performed by the worker (J) in each process facility based on statistics on the worker (J)'s training results recorded in the server (20).

[0128] The server (20) accumulates, stores, and manages training information and its results conducted by the worker (J). Each time the worker (J) conducts training at the terminal (30), the server (20) receives training content and its results from the terminal (30) and stores them in a database. Based on this, the server (20) can update the type, content, and training scenario of the training information and provide this to the terminal (30).

[0129] The simulation system of the embodiment plans and provides a training curriculum that allows each worker (J) to receive training quickly and efficiently, reflecting the different work history of each worker (J). To this end, the battery cell assembly process simulation system of the embodiment includes a training content selection logic that extracts the work history of the worker corresponding to the information of the worker input through the input interface from the server (20) and constructs a training curriculum to be provided to the terminal based on the extracted work history.

[0130] The above-described selection logic may be a software program. The selection logic may be executed on the server (20) or the terminal (30). The selection logic may be implemented in the form of a computer program stored on a computer-readable storage medium. That is, the computer program may include instructions for implementing the selection logic, and the program instructions may be stored on a computer-readable storage medium. The computer program may include a mobile application.

[0131] According to an embodiment, the computer-readable storage medium may include magnetic media such as hard disks, floppy disks, and magnetic tapes, optical media such as CD-ROMs, DVDs, magneto-optical media such as floptical disks, and hardware devices specially configured to store and execute computer program instructions such as ROMs, RAMs, flash memories, and the like. The computer program instructions may include machine language codes generated by a compiler and high-level language codes that can be executed by a computer using an interpreter, etc.

[0132] The above training content selection logic provides changed training information as training information for training facilities that have been partially changed from the existing facilities, if it is confirmed based on the experience information of the training participant that the worker has experience with existing facilities.

[0133] Referring to FIG. 20, the method for operating the simulation system includes a step (S1) of receiving information about a worker (J), a step (S2) of extracting the work history of the worker (J) corresponding to the received information, a step (S3) of constructing a training curriculum by selecting training information for training facilities based on the extracted work history, and a step (S4) of providing the constructed training curriculum to the worker's training terminal (30).

[0134] The worker's information can be entered through the input interface of the terminal (30). The entered worker's information is transmitted to the server (20). The server (20) extracts the worker's work history corresponding to the received information. Referring to Fig. 12, the work history includes the worker's (J) experience with the equipment.

[0135] According to the first embodiment, the task of constructing a training curriculum based on the extracted work history can be performed on the server (20). That is, the training content selection logic can be executed on the server (20). The training curriculum can be constructed by selecting appropriate training information based on the worker's work history among the training information on training facilities stored on the server (20). The server can provide training information corresponding to the constructed training curriculum to the terminal.

[0136] According to the second embodiment, the server (20) transmits the extracted work history of the worker to the terminal (30), and the terminal (30) can construct a training curriculum based on the received work history. That is, the above-described training content selection logic can be executed in the terminal (30). Referring to FIG. 21, the training curriculum can be constructed by selecting suitable training information based on the worker's work history among training information on training facilities stored in the server. The terminal (30) can request training information corresponding to the constructed training curriculum from the server (20). In addition, the server (20) can provide the requested training information to the terminal (30).

[0137] The above educational content selection logic, based on the work history of the worker (J), can construct a curriculum that provides information that the educational facility is identical to the existing facility and that the worker has experience with the existing facility, and provides the worker with an opportunity to choose whether to complete training for the educational facility. For convenience of explanation, this is referred to as the first logic (L1, L3, L5).

[0138] The above training content selection logic, based on the work history of the worker (J), can select modified training information based on the assumption that the training facility is a facility that has been partially modified from the existing facility and for which the worker has experience, and build the training curriculum. For convenience of explanation, this is referred to as the second logic (L2, L4, L7).

[0139] The above training content selection logic, based on the work history of the worker (J), can select new training information based on the assumption that the training facility is new, for a training facility that is identical to or has been partially modified from an existing facility and for which the worker has no experience with the existing facility, and build the training curriculum. For convenience of explanation, this is referred to as the third logic (L2, L4, L6).

[0140] The above training content selection logic can be used to build the training curriculum by selecting new training information for new facilities, assuming that the facilities are new. For convenience, this is referred to as the fourth logic (L1, L2, L6).

[0141] For example, referring to FIGS. 11 and 12, the above-described educational content selection logic constructs an educational curriculum for worker 1 according to the first logic for facility A, according to the second logic for facility B2, according to the second logic for facility C2, according to the fourth logic for facility F, and according to the first logic for facility E.

[0142] And for worker 2, the training curriculum is built according to the third logic for facility A, according to the third logic for facility B2, according to the third logic for facility C2, according to the fourth logic for facility F, and according to the third logic for facility E.

[0143] And for worker 3, the training curriculum is built according to the second logic for facility A, according to the second logic for facility B2, according to the first logic for facility C2, according to the fourth logic for facility F, and according to the first logic for facility E.

[0144] According to the present invention, the curriculum can be optimally constructed according to the experience status of the worker (J), thereby obtaining the most efficient educational effect.
