Background Technology

[0003] Process monitoring technology refers to technology capable of providing real-time information regarding the progress of product manufacturing processes. In the case of large-scale manufacturing processes involving a significant number of personnel, process monitoring systems are established to enhance the efficiency of process management; however, verifying detailed work status in real time remains difficult due to system limitations.

[0004] In particular, small and medium-sized enterprises (SMEs) where most manufacturing processes are performed manually face challenges not only in process automation but also in monitoring various production statuses within the factory in real time, due to the variability, complexity, and diversity of the work environment. Consequently, it may be difficult to effectively predict product delivery times and operate manufacturing lines flexibly.

[0005] Although smart factory systems are being developed to address these issues, small and medium-sized enterprises (SMEs) that rely on manual labor may face time and financial difficulties in adopting the system all at once due to their circumstances. Prior art literature

[0057] Figure 3 is a diagram illustrating the functional configuration of the process monitoring device of Figure 1.

[0058] Referring to FIG. 3, a process monitoring device (130) can perform a process monitoring method using a drawing according to the present invention through a processor (210). To this end, the processor (210) may include a reference information receiving unit (310), a progress status collection unit (330), an interface creation unit (350), a visualization display unit (370), and a control unit (not shown in FIG. 3).

[0059] At this time, the embodiments of the present invention are not required to include all of the above functional configurations simultaneously; depending on each embodiment, some of the above functional configurations may be omitted, or some or all of the above functional configurations may be selectively included. The operation of each configuration will be described in detail below.

[0060] The reference information receiving unit (310) may receive reference information including process-specific unit drawings regarding the manufacturing process of a specific product. Here, the manufacturing process may correspond to a process of producing a final product using raw materials, and the reference information may correspond to information including reference values, guidelines, and procedures for performing the manufacturing process normally. That is, the reference information may be utilized as existing data of the process monitoring system (100) to monitor the progress of the process and to diagnose abnormalities in the manufacturing process. In particular, the reference information may include process-specific unit drawings for data visualization. Process-specific unit drawings may correspond to partial images of products produced at each stage of the manufacturing process. For example, in vehicle manufacturing, process-specific unit drawings may correspond to drawing images of vehicle parts (e.g., wheels, car body, doors, etc.) assembled at each process.

[0061] Additionally, the reference information receiving unit (310) may provide an input interface for receiving reference information related to the manufacturing process, and the user may input various reference information through the input interface. The reference information received by the reference information receiving unit (310) may be stored and managed in the database (150).

[0062] The progress status collection unit (330) can receive progress status data by process from at least one data input terminal (110) placed at the manufacturing site of a specific product. The manufacturing site may correspond to an actual workspace where a specific product is produced using raw materials, and may include a production line, a workbench, and an assembly space. At the manufacturing site of a specific product, a data input terminal (110) may be installed or placed at each process stage, and a worker or manager of the corresponding process stage may input work information through the data input terminal (110) in the event of work start, work end, occurrence of a breakdown, or occurrence of a defect. That is, the progress status data by process may correspond to data indicating the progress of each process stage and may include information such as work progress, production volume, defect rate, and resource usage.

[0063] More specifically, work progress may correspond to data indicating how much progress has been made on each task, and may include the start time, end time, and progress rate. Production volume may correspond to data indicating the quantity of products produced during a specific period, and the defect rate may correspond to data indicating the proportion of defective products among the produced products. Additionally, resource usage may correspond to data indicating the amount of resources used in the manufacturing process, and may include manpower, materials, and energy.

[0064] Additionally, the progress status collection unit (330) can operate in conjunction with the data input terminal (110) to receive progress status data by process, and the progress status data by process collected by the progress status collection unit (330) can be stored and managed in the database (150).

[0065] The interface generation unit (350) can generate a monitoring interface in response to a monitoring request regarding a manufacturing process. Here, the monitoring request may correspond to an act in which a user requests information from the system to obtain information about the manufacturing process. In particular, the user may select the type of information to be requested, such as real-time data, historical data, or analysis results. Additionally, the user may select the target of the information to be requested, such as a specific process, task, resource, or period. The interface generation unit (350) can configure the monitoring interface in a form effective for the user to check and analyze monitoring data regarding the manufacturing process, and can add various visualization elements, analysis tools (e.g., filtering, sorting, and aggregation functions), and control functions (e.g., starting / stopping tasks and changing settings).

[0066] Additionally, the interface generation unit (350) can provide an intuitive monitoring interface so that the user can more easily understand and analyze the manufacturing process. To this end, the interface generation unit (350) can analyze the user's monitoring request to determine the request type and the request target, and can configure an optimal monitoring interface based on the determined type and target. The interface generation unit (350) can quickly generate a monitoring interface using a predefined template, and can also generate a monitoring interface directly defined by the user through a programming language. The interface generation unit (350) can configure the monitoring interface using various widgets (e.g., graphs, charts, gauges, etc.).

[0067] The visualization display unit (370) can visualize and display process progress data on process unit drawings on the monitoring interface. The visualization display unit (370) can express data using various visualization techniques such as graphs, color coding, and symbols. The visualization display unit (370) can basically utilize 2D drawings or 3D models for visualizing process unit drawings, and can simulate the manufacturing site and visualize progress using VR or AR technology as needed. The visualization display unit (370) can dynamically update and display process unit drawings according to the progress of the process.

[0068] In one embodiment, the visualization display unit (370) can analyze progress status data by process to calculate the progress rate for each process and display the calculated progress rate through a unit drawing for each process. For example, the visualization display unit (370) can extract the number of tasks completed at each process stage from the progress status data by process and calculate the progress rate based on this. As another example, the visualization display unit (370) can calculate the progress rate by extracting the time spent at each process stage from the progress status data by process. The visualization display unit (370) can calculate the progress rate of the entire process by integrating the progress rates of each process. Additionally, the visualization display unit (370) can visually display the progress rate of each process stage or the progress rate of the entire process on a drawing using various visualization methods, such as color display methods, graph representation methods, and text display methods.

[0069] In one embodiment, the visualization display unit (370) may change and display some of the visual representation methods, including the color, size, and transparency of the unit drawing for each process, according to the calculated progress rate. For example, the visualization display unit (370) may display gray when the progress rate is 0%, yellow when it is 50%, and green when it is 100%. Additionally, the visualization display unit (370) may change and display the size of the unit drawing for each process according to the calculated progress rate. That is, the visualization display unit (370) may proportionally change the size of the drawing according to the progress rate, or display the drawing size of the ongoing process step larger than other process steps to emphasize it. Additionally, the visualization display unit (370) may change and display the transparency of the unit drawing for each process according to the calculated progress rate. For example, the visualization display (370) can be displayed with 100% transparency when the progress is 0%, 50% transparency when the progress is 50%, and 0% transparency when the progress is 100%, so that the process step is gradually emphasized as it progresses.

[0070] In one embodiment, the visualization display unit (370) may additionally display detailed information about a specific process selected by a user on a monitoring interface. Here, the detailed information about the specific process may include work information such as the type of work, standard work time, estimated completion time, actual time required, work progress rate, and worker information of the specific process. Additionally, the detailed information may include: 1) resource information such as the type, quantity, usage time, and resource status of the resources used; 2) production information such as the quantity of products produced, defect rate, and production graph; 3) quality information such as inspection results, defective product information, and defect rate graph; and 4) problem information such as the problem that occurred, the time of problem occurrence, and the status of problem resolution. Additionally, the visualization display unit (370) may provide a separate detailed interface for displaying detailed information on the monitoring interface. That is, when a user selects process 'A' on the monitoring interface, the visualization display unit (370) may display detailed information about process 'A' through the detailed interface.

[0071] In one embodiment, the visualization display unit (370) can display the process progress history for a specific time interval set by the user on the monitoring interface. The process progress history may correspond to data that records the progress of the process in chronological order during a specific period. The user can specify the time interval in units such as minutes, hours, and days of the week, and the visualization display unit (370) can generate and display the process progress history by querying the progress status data for each process for the time interval specified by the user.

[0072] In one embodiment, the visualization display unit (370) can display whether an abnormality has occurred in the manufacturing process by comparing reference information and progress status data by process on a monitoring interface. The visualization display unit (370) can diagnose that an abnormality has occurred in the process if the difference resulting from comparing production volume, work time, defect rate, resource usage, and worker information exceeds a normal range. Additionally, the visualization display unit (370) can display the process in which an abnormality has been detected using colors, symbols, text, etc., to distinguish it from the normal process.

[0073] For example, the visualization display (370) may display in green when normal, yellow when an abnormality of a warning level occurs, and red when a serious abnormality occurs. The visualization display (370) may use symbols indicating insufficient production, delayed work time, increased defect rate, excessive resource usage, and shortage of workers, and may display detailed information about the abnormality in text form, such as the type of abnormality, time of occurrence, cause of occurrence, and scope of impact.

[0074] In one embodiment, the visualization display unit (370) independently receives process progress status data from a plurality of data input terminals (110), updates the process progress status data by reflecting it in each process unit drawing, and can display each process unit drawing on an independent layer on a monitoring interface. The visualization display unit (370) can perform an operation to verify the accuracy of the data received from each data input terminal (110) and can perform an operation to convert the received data into a format suitable for visualization display.

[0075] Additionally, each process unit drawing can be displayed as an independent layer on the monitoring interface, and the user can select and display only the desired process unit drawing layer. To this end, the visualization display unit (370) can provide a function for setting layers through the monitoring interface. Accordingly, the user can adjust the transparency of each layer so that the desired process unit drawing is highlighted and displayed.

[0076] Additionally, the visualization display unit (370) can group and display related process unit drawings among the layers displayed on the monitoring interface. More specifically, the visualization display unit (370) can group process steps that are performed continuously in the product manufacturing process. For example, the visualization display unit (370) can group and display welding, painting, and assembly process steps of the car body manufacturing process, group them according to product type, or group process steps of the same production line.

[0077] Additionally, the visualization display unit (370) can display grouped process unit drawings by grouping them with the same type of boundary (border) and can display them using different colors for each group. The visualization display unit (370) can display the name of the group in the form of a label and can reduce the grouped process unit drawings so that the progress of the overall group can be understood rather than the individual drawings.

[0078] Additionally, the visualization display unit (370) can compress and display the groups into upper groups or divide and display them into lower groups based on the number of groups displayed on the monitoring interface. For example, if the number of groups displayed on the monitoring interface exceeds a preset first threshold, the visualization display unit (370) can reduce the number of groups displayed by grouping those groups into a smaller number of upper groups. If the number of groups is less than a preset second threshold, the visualization display unit (370) can increase the number of groups displayed by dividing those groups into a larger number of lower groups.

[0079] Additionally, the visualization display unit (370) can dynamically adjust the number of groups displayed through interaction with the user on the monitoring interface. For example, when the user zooms in to enlarge the screen, the number of groups displayed can be increased by dividing the currently displayed groups into a larger number of subgroups. Conversely, when the user zooms out to reduce the screen, the number of groups displayed can be reduced by grouping the currently displayed groups into a smaller number of upper groups.

[0080] In one embodiment, the visualization display unit (370) may display unit drawings for each process in an animated format according to chronological order or process order. For example, a car body assembly animation may be implemented to display the process of assembling a car body in chronological order or process order through unit drawings for each process. In this case, the animation effect may be visualized through the color, size, and transparency of the drawings.

[0081] In one embodiment, the visualization display unit (370) may divide the manufacturing process into a plurality of sub-processes and group the plurality of sub-processes based on the location of the data input terminal (110) and the relationship between the sub-processes. For example, the vehicle body manufacturing process may be divided into sub-processes such as body welding, body painting, and body assembly. The visualization display unit (370) may group processes among the sub-processes that are performed in succession such that the distance between the data input terminals (110) placed in each process is within a specific distance. The visualization display unit (370) may display the grouped sub-processes by applying methods such as grouping them with the same border or visualizing them with the same color.

[0082] In one embodiment, the visualization display unit (370) may generate a representative unit drawing by integrating process-specific unit drawings for each grouped sub-process group and visualize and display process-specific progress data on the representative unit drawing. Here, the sub-process group may correspond to a set of grouped sub-processes, and the representative unit drawing may correspond to a single drawing generated by integrating individual process-specific unit drawings belonging to the sub-process group. That is, the representative unit drawing may correspond to a drawing that summarizes and expresses the progress status of all sub-processes within the group.

[0083] Additionally, the visualization display unit (370) can display representative unit drawings through independent layers on the monitoring interface. The visualization display unit (370) can display the layers of the representative unit drawings and the group layers together by overlapping them.

[0084] A control unit (not shown in FIG. 3) can control the overall operation of the process monitoring device (130) and manage the control flow or data flow between the reference information receiving unit (310), the progress status collection unit (330), the interface creation unit (350), and the visualization display unit (370).

[0086] FIG. 4 is a flowchart illustrating a process monitoring method using a drawing according to the present invention.

[0087] Referring to FIG. 4, the process monitoring device (130) can receive reference information regarding the manufacturing process of a specific product through a processor (210) (steps S410, S430). Here, the reference information may include standard time per process, drawing images per process, etc. The process monitoring device (130) can receive field work status information from at least one data input terminal (110) deployed at the manufacturing site of a specific product through the processor (210) (step S450). Here, the field work status information may include progress status data per process.

[0088] Additionally, the process monitoring device (130) can generate a monitoring interface in response to a monitoring request regarding a manufacturing process via the processor (210), and can visualize and display process-specific progress data on a process-specific unit drawing on the monitoring interface. For example, the process monitoring device (130) can calculate the work time for each process (step S470) and can visualize and display the overall work progress on a process-specific drawing image (step S490).

The process monitoring device (130) can execute a separate program for inputting reference information, and the user can input standard time per process, process-specific drawing images, etc., as reference information. The reference information may include process name, work time, process drawing, and number of work. The process monitoring device (130) can build standard information for various manufacturing processes in advance as a DB, and can recommend data regarding some items based on the standard information during the process of the user inputting reference information.

[0092] Referring to FIG. 6, the process monitoring device (130) can receive process-specific progress status data from at least one data input terminal (110) deployed at the manufacturing site of a specific product. The process monitoring device (130) can receive progress status information regarding the start, stop, and completion of work for each process from the data input terminal (110) through a separate program for inputting process-specific progress status data. The process-specific progress status data may include information regarding the work name, worker, start / instruction time, and issues.

[0094] FIG. 7 is a drawing illustrating an embodiment of a work progress monitoring screen according to the present invention.

[0095] Referring to FIG. 7, the process monitoring device (130) can visualize and display process progress status data (710) on process unit drawings (730) on the monitoring interface. The process unit drawings (730) can be displayed on independent layers for each process stage, and the monitoring interface can display multiple layers superimposed. Accordingly, the drawing image of the product can be changed and displayed in the form of a finished product according to the process progress stage. In addition, the process monitoring device (130) can distinguish each process unit drawing (730) by process and display them in different colors.

[0096] For example, in figure (a) of FIG. 7, the vehicle head portion and the main lower portion (731) portion may be shown, and in figure (b), the crane (733) portion assembled on the upper part of the main lower portion (731) portion may be shown together as the assembly process progresses. At this time, the main lower portion (731) portion and the crane (733) portion may be shown on separate layers and may be distinguished by different colors.

[0097] Meanwhile, the process monitoring device (130) can calculate the progress rate for the entire process based on the progress status data (710) for each process, and can display the overall progress rate (750) by distinguishing it by color on the monitoring interface. For example, as the entire process progresses in figures (a) and (b) of FIG. 7, the overall progress rate (750) can be displayed with increasing emphasis. The user can intuitively and easily recognize the progress status of the manufacturing process through various visual information, such as the progress status data (710) for each process, the unit drawing (730) for each process, and the overall progress rate (750), displayed through the monitoring interface.

[0098] In one embodiment, the process unit drawing (730) can be stored in the system's process reference information along with the process standard time by making the background transparent. The process monitoring device (130) can record the production time when work begins for each process, and the production completion rate (or work progress rate) can be calculated and displayed as the work time relative to the standard time. That is, a process that has already been completed can be displayed as 100% regardless of time, and before production is completed, it can be displayed with correction so as not to exceed 99%. Accordingly, even if work is carried out beyond the standard time, the maximum progress rate per process can be limited to 99%. Products for which production / work instructions have been issued can be displayed as 2D images in a grid format according to the progress rate on the monitoring screen, and a worker or manager can visually check them at once. The process monitoring device (130) can also display the work status by applying the progress rate for each process to products that need to move through multiple processes.

[0100] Although the present invention has been described above with reference to preferred embodiments, those skilled in the art will understand that various modifications and changes can be made to the invention without departing from the spirit and scope of the invention as described in the following claims.
