Description

[Technical Field]

[0001] The present invention relates to a sewing support method, a sewing support program, a storage medium, and a sewing device for supporting sewing. [Background technology]

[0002] Patent Document 1 discloses a system in which a manufacturer's service department creates failure analysis data based on sewing machine sewing parameter data or failure data acquired via the Internet and distributes the data to the sewing machine. An operator can optimize the sewing machine system based on the distributed failure analysis data. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-177673 Summary of the Invention [Problem to be solved by the invention]

[0004] In Patent Document 1, the failure analysis data created by the service department is data that is narrowed down in order of priority based on the sewing parameters transmitted from the sewing machine. Therefore, even if the current malfunction is similar to the previous malfunction, the service department creates the same failure analysis data as the previous malfunction. Therefore, if the previous malfunction was resolved after, for example, multiple attempts, the same attempts must be made to resolve the current malfunction, which is time-consuming.

[0005] An object of the present invention is to provide a sewing support method, a sewing support program, a storage medium, and a sewing device that can quickly improve problems. [Means for solving the problem]

[0006] According to a first aspect of the present invention, there is provided a sewing support method for supporting sewing by a sewing device using a mobile terminal, the sewing support method comprising: a first acquisition step of acquiring data on various states of the sewing device as first status data from the sewing device, an analysis step of analyzing the first status data, a correspondence presentation step of extracting, from a plurality of improvement means that associate causes of various states with improvements to the various states and contribute to improving the various states, the improvement means corresponding to the analysis results as countermeasures, and presenting the extracted countermeasures on a screen of the mobile terminal in accordance with a predetermined adaptation order for the improvement means, a second acquisition step of acquiring data on various states of the sewing device as second status data from the sewing device after the countermeasures have been presented, a first determination step of determining whether the countermeasures are effective based on the first status data and the second status data, and a change step of changing the adaptation order for the improvement means based on the determination result.

[0007] When a malfunction or the like occurs in the sewing device, the mobile terminal acquires and analyzes data related to the malfunction as first status data, and presents improvement measures corresponding to the analysis results as countermeasures. At this time, the mobile terminal presents the countermeasures according to a preset adaptation order. After the user addresses the malfunction according to the countermeasures, the mobile terminal acquires the status of the sewing device as second status data and compares it with the first status data. Based on the comparison result, the mobile terminal changes the adaptation order of the countermeasures that were effective in resolving the malfunction. As a result, when a similar malfunction occurs next time or later, the mobile terminal can present previously effective countermeasures with a higher priority. By updating the adaptation order, the mobile terminal can reduce the number of attempts the user needs to make to resolve the malfunction the next time a malfunction occurs, thereby enabling the malfunction to be resolved more quickly. Furthermore, by presenting highly effective countermeasures with a higher priority, the mobile terminal can make it easier for even users who are unfamiliar with resolving malfunctions to select an appropriate countermeasure.

[0008] In a first aspect, the first status data and the second status data may include at least one of setting data indicating setting values ​​of sewing parameters and defect data indicating a defect. The sewing device may include a display device and may display a status image on the display device, the status image being encoded with at least one of the setting data and the defect data. The first and second acquisition steps may include a photographing step of photographing the status image and a decoding step of decoding the first status data or the second status data from the photographed status image. The portable terminal may acquire the first status data and the second status data by photographing the status image displayed by the sewing device and decoding the data. This eliminates the need for a separate connection to the sewing device, as compared to, for example, a wired or wireless connection to the sewing device. Therefore, the portable terminal may acquire the first status data and the second status data from multiple types of sewing devices and present appropriate countermeasures for each.

[0009] In the first aspect, if the analysis result of the analysis step indicates that the first status data does not include the defect data, the mobile device may further include an information presenting step of presenting multiple types of defects on the screen of the mobile device. For example, if the sewing device is unable to detect a defect discovered by the user, the mobile device may present the types of defects to the user so that the user can select one. The mobile device may then promptly improve the defect by allowing the user to address the defect according to the indicated response measures.

[0010] In a first aspect, the mobile terminal may include a first receiving step of receiving a selection of a type of defect corresponding to the state of the sewing device from a plurality of types of defects displayed on the screen, a plurality of countermeasures including causes of defects causing the selected type of defect and solutions therefor, presented on the screen in accordance with the order of suitability in the solution presenting step, and then a narrowing down step of selecting one or more countermeasures that exhibit symptoms corresponding to the state of the sewing device, a second receiving step of receiving a selection of the countermeasure corresponding to the state of the sewing device from the narrowed down countermeasures, and an improvement presenting step of presenting the determined countermeasure on the screen of the mobile terminal.The mobile terminal can further narrow down the countermeasures appropriate for the content of the defect from the countermeasures including causes of the defect selected by the user, thereby achieving prompt and reliable improvement of the defect.

[0011] In a first aspect, the method may include a first storing step of storing the countermeasure selected in the second receiving step in a storage device of the mobile terminal in association with the first status data, a second storing step of storing a determination result of the effectiveness of the countermeasure in association with the second status data obtained by determining the effectiveness of the countermeasure in association with the first status data, and a list display step of displaying a list of the countermeasures associated with the first status data and the effectiveness of the countermeasure associated with the second status data related to the first status data on the screen of the mobile terminal. The mobile terminal can display a list of the countermeasures and the effectiveness as a history of previous attempts to correct defects in the sewing device, in association with each other. This allows the user to quickly correct the defect based on the history.

[0012] According to a second aspect of the present invention, there is provided a sewing support program for causing a mobile device to function and supporting sewing by a sewing device, the sewing support program causing a computer of the mobile device to execute the following steps: a first acquisition step of acquiring first status data relating to various states of the sewing device from the sewing device, an analysis step of analyzing the first status data, a response presentation step of selecting, from among a plurality of improvement measures contributing to improving the various states, countermeasures corresponding to the analysis results, and presenting the selected countermeasures on a screen of the mobile device in accordance with a predetermined adaptation order for the improvement measures, a second acquisition step of acquiring data relating to the various states of the sewing device as second status data from the sewing device after the countermeasures have been presented, a first determination step of determining whether the countermeasures are effective based on the first status data and the second status data, and a change step of changing the adaptation order for the improvement measures based on the determination result, thereby achieving the same effects as the first aspect.

[0013] According to a third aspect of the present invention, there is provided a storage medium storing a program for causing a computer of a mobile terminal for assisting sewing by a sewing device to execute the following steps: a first acquisition step of acquiring first status data relating to various states of the sewing device from the sewing device, an analysis step of analyzing the first status data, a response presentation step of selecting, from a plurality of improvement measures contributing to improving the various states, countermeasures corresponding to the analysis results and presenting the selected countermeasures on a screen of the mobile terminal in accordance with a predetermined adaptation order for the improvement measures, a second acquisition step of acquiring, after the presentation of the countermeasures, data relating to various states of the sewing device as second status data from the sewing device, a first determination step of determining whether the countermeasures are effective based on the first status data and the second status data, and a change step of changing the adaptation order for the improvement measures based on the determination result, thereby achieving the same effects as the first aspect.

[0014] According to a fourth aspect of the present invention, there is provided a sewing device in which sewing is assisted by a mobile terminal, the sewing device comprising: an acquisition means for acquiring, when a malfunction occurs in a sewing operation, malfunction data indicating the malfunction and setting data indicating set values ​​of sewing parameters; a generation means for generating a status image in which the malfunction data and the setting data are encoded; and a display means for displaying the status image on a display screen of a display device. By displaying the status image in which data indicating the malfunction and parameters are encoded, the sewing device can cause the mobile terminal to acquire the first status data and the second status data without connecting to the mobile terminal via a wired or wireless connection.

[0015] In a fourth aspect, the sewing device may further include a receiving means for receiving an input of an instruction to generate the status image, and when the instruction to generate the status image is received, the acquiring means may acquire the setting data, and the generating means may generate the status image by encoding the setting data. Even if a defect cannot be detected, the sewing device may cause the mobile terminal to acquire the first status data and the second status data by presenting the status image of the setting data in accordance with the input instruction.

[Figure 8] 10 is a flowchart of a history display process executed in the mobile terminal 2. DETAILED DESCRIPTION OF THE INVENTION

[0017] The following description will discuss specific embodiments of the present invention with reference to the drawings. The drawings are used to explain technical features that the present invention can employ, and the configurations of the devices described are merely illustrative examples and are not intended to limit the scope of the present invention.

[0018] An overview of the sewing support system 1 will be described with reference to FIG. 1. The sewing support system 1 includes a mobile terminal 2 and a plurality of sewing devices 3. The sewing support system 1 is a system that uses the mobile terminal 2 to support dealing with various conditions that occur in the sewing devices 3. In this embodiment, the explanation will be given taking as an example a case where support for dealing with various conditions is provided by presenting a method for resolving a problem that occurs during sewing operations. Note that the various conditions are not limited to problems with sewing operations. The sewing support system 1 may also be a system that presents various information about the sewing devices 3, such as, for example, "The power won't turn on," "I don't know how to install an option," or "I want to know the contact information for support."

[0019] The electrical configuration of the mobile terminal 2 will be described. The mobile terminal 2 is a portable terminal device such as a smartphone or tablet terminal. The mobile terminal 2 includes a CPU 21 that handles control. The CPU 21 is electrically connected to a ROM 22, a RAM 23, a storage unit 24, a display unit 26, an input unit 27, a camera 28, and a communication I / F 29 via an interface circuit. The ROM 22 stores a boot program, a BIOS, etc. The RAM 23 stores a timer, a counter, a flag, temporary data, etc. The storage unit 24 is a non-volatile storage medium such as a flash memory. The storage unit 24 stores the processing programs executed by the CPU 21, an OS, and various tables.

[0020] The display unit 26 is, for example, a liquid crystal display device and can display various information. The input unit 27 is, for example, a touch panel and accepts operation input. The camera 28 generates and outputs a captured image of the capture range. The communication I / F 29 includes a communication module for connecting to a LAN and a public line network via an access point (not shown), and a communication module for connecting directly to the public line network.

[0021] The electrical configuration of the sewing device 3 will be described. The sewing device 3 is equipped with a CPU 31 that controls the sewing device 3. The CPU 31 is electrically connected to a ROM 32, a RAM 33, a memory unit 34, a drive circuit 35, a display unit 37, an operation unit 38, and a sensor 39 via an interface circuit. The ROM 32 stores a boot program and the like. The RAM 33 stores a timer, a counter, a flag, temporary data, various tables, and the like. The memory unit 34 is a non-volatile storage medium such as a flash memory. The memory unit 34 stores programs for processing executed by the CPU 31, various tables, and the like. The sewing device 3 does not need to have all of the above electrical configuration built in. For example, part of the electrical configuration of the sewing device 3 may be connected to an external device via an interface. In this case, the sewing device 3 may be equipped with a CPU, ROM, and RAM that control the electrical configuration provided inside the sewing device 3, as well as a CPU, ROM, and RAM that control the electrical configuration provided outside the sewing device 3.

[0022] The drive circuit 35 drives the drive motor 36A in response to a signal output from the CPU 31. The drive motor 36A collectively refers to various motors, such as a main motor that synchronously drives the needle bar and the shuttle, a feed motor that moves the holding mechanism that holds the sewing workpiece in the X-axis and Y-axis directions, and a thread tension motor that generates tension in the thread tension regulator. The encoder 36B detects the rotational position of the output shaft of the drive motor 36A. The display unit 37 is, for example, a liquid crystal display device and can display various information. The operation unit 38 includes a pedal, operation keys, a touch panel, etc. The sensor 39 collectively refers to various sensors that detect the status of each mechanism of the sewing device 3. For example, a magnetic sensor provided in a tension detection mechanism through which the upper thread is guided via the thread tension regulator detects the tension of the upper thread.

[0023] Malfunctions that may occur in the sewing device 3 are described below. As an example of a malfunction, the sewing device 3 may produce a sewing defect. A sewing defect indicates that a normal stitch cannot be formed during the sewing operation. Sewing defects include thread loss, skipped stitches, false stitches, and poor thread tension. A thread loss is a defect in which the upper thread comes off the needle. A skipped stitch is a failure of the hook to capture the upper thread during sewing, resulting in a normal stitch not being formed on the fabric. A false stitch is a defect in which the bobbin thread is not fed properly, resulting in a stitch being formed only by the upper thread. A thread tension defect is a mismatch between the upper and bobbin threads that form a stitch on the fabric when the take-up lever lifts the upper thread. For example, if the upper thread is too tightly entangled with the bobbin thread, the fabric near the stitch will shrink. The sewing device 3 stores detection criteria corresponding to each of thread loss, skipped stitches, false stitches, and poor thread tension in the memory unit 34. Therefore, the sewing device 3 can identify the type of sewing defect. For example, based on the tension of the upper thread detected by the magnetic sensor of the tension detection mechanism, the CPU 31 can determine whether a sewing defect has occurred, and if a sewing defect has occurred, which sewing defect has occurred: loose thread, skipped stitch, fake stitch, or poor thread tightening.

[0024] Next, with reference to FIGS. 2 and 3, a process for correcting a malfunction using the mobile terminal 2 when a malfunction occurs in the sewing device 3 in the sewing support system 1 will be described. When the CPU 31 of the sewing device 3 detects the occurrence of a malfunction, including a sewing defect, through a diagnosis based on the detection results of the sensor 39 and the values ​​of the encoder 36B, the CPU 31 collects malfunction data indicating the details of the detected malfunction and setting data (setting values ​​of sewing parameters) indicating the operating state of the sewing device 3 (P2). The malfunction data is data for identifying the type of malfunction. For example, if the malfunction is a sewing defect, the data indicates whether the sewing defect is a thread break, a skipped stitch, or poor thread tightening. The setting data is information indicating the current operating state of the sewing device 3, and includes the "date and time," "model name (type)," "serial number," "number of stitches," "program number being sewn," "sewing pattern," "sewing speed," "needle thread tension," "rotary hook phase," "needle height," "operating time since power-on," "operating time since shipment (cumulative)," "production number for the selected sewing pattern," "thread information," "material (fabric) information," etc. This includes the output of the sensor 39 and the value acquired by the encoder 36B during sewing operation. As shown in Fig. 2, the CPU 31 generates a code image Q by encoding the defect data and setting data, and displays it on the display unit 37 (P3). The code image Q is, for example, a QR code (registered trademark).

[0025] However, in a situation where the sewing device 3 is unable to detect the malfunction, the user X may notice the occurrence of the malfunction (P1). In this case, the user X operates the operation unit 38 of the sewing device 3 (P2) to display the code image Q on the display unit 37 (P3). The code image Q generated in this case is an image obtained by encoding the setting data (setting values ​​of the sewing parameters) because the sewing device 3 is unable to detect the occurrence of the malfunction.

[0026] When a defect in the sewing device 3 is improved using the mobile terminal 2, a sewing support program (app) is installed in the storage unit 24 of the mobile terminal 2. The CPU 21 of the mobile terminal 2 may acquire the sewing support program by downloading it from a provider server via a public line network, or by connecting a storage medium storing the sewing support program to the mobile terminal 2 via an external interface (not shown) and reading the sewing support program. When the sewing support program is started, the mobile terminal 2 activates the camera 28 to capture a code image Q displayed on the display unit 37 of the sewing device 3 (P4). The CPU 21 of the mobile terminal 2 decodes the captured code image Q to acquire the defect data and setting data. Note that the CPU 21 acquires only the setting data from the code image Q generated based on the operation of the user X.

[0027] As shown in FIG. 3, when the sewing device 3 detects a malfunction, the type of the malfunction is identified by the malfunction data. In this case, the CPU 21 of the mobile terminal 2 presents the user X with a selection screen for selecting the cause of the malfunction (P6). On the other hand, when the user X discovers a malfunction, the type of the malfunction is not identified. In this case, the CPU 21 of the mobile terminal 2 presents the user X with a selection screen for selecting the type of malfunction (P5). The types of malfunction are displayed on the display unit 26 as selection buttons that the user X can operate. When the user X selects the type of malfunction that corresponds to the malfunction that has occurred in the sewing device 3, the CPU 21 presents the user X with a selection screen for selecting the cause of the malfunction, as described above (P6).

[0028] There are multiple causes (symptoms) of a single defect. For example, if poor thread tightening occurs, possible causes of the defect include "idling of the bobbin," "needle bending at the edge of the multi-layered portion, increasing fabric resistance," "increased fabric resistance," and "fluttering of the fabric." The CPU 21 lists on the display unit 26 improvement approaches that associate the causes of the defect that cause the type of defect detected and identified by the sewing device 3 with the improvement measures, and displays them as selection buttons that can be operated by the user X.

[0029] The improvement approaches are ranked in advance for each type of defect in order of likelihood of occurrence (in order of frequency of causing the defect), and are stored in the storage unit 24. In the following description, the ranked order is referred to as the adaptation order. On the selection screen for improvement approaches displayed on the display unit 26, the improvement approaches are displayed in order (from top to bottom in the example of FIG. 3) so that the improvement approaches with higher adaptation orders are displayed at the top for easier selection. In FIG. 3, for convenience, only the causes of the defect included in the improvement approaches are displayed on the selection buttons, but the causes and improvements may also be displayed on the selection buttons.

[0030] Furthermore, as will be described in detail later, the order of application of improvement approaches that were effective in resolving the problem when the sewing support program was previously executed has been changed and they are displayed at the top. Therefore, the user X can select an improvement approach that is likely to be effective in resolving the problem he or she is facing, referring to the order of the improvement approaches displayed on the display unit 26. When the user X selects an improvement approach, the CPU 21 displays the cause of the problem and the improvement measures associated with the selected improvement approach on the display unit 26 (P9). The user X aims to resolve the problem of the sewing device 3 by implementing the displayed improvement measures.

[0031] On P6 in FIG. 3, when the selection buttons for the improvement approaches indicating the cause of the defect are displayed, the display unit 26 also displays a "diagnose" button. When the user X selects the "diagnose" button, the CPU 21 displays a consultation screen on the display unit 26 to inquire of the user X about the location and circumstances of the defect, which are difficult to detect with the sewing device 3, for a more accurate diagnosis (P7). A combination of answers to the consultation and an improvement approach are associated in advance. When the user X inputs answers to the displayed questions, the CPU 21 narrows down the improvement approaches. As a result of the narrowing down, the CPU 21 displays candidate improvement approaches that may be effective for improving the defect on the display unit 26 (P8). Furthermore, the improvement approaches excluded by the narrowing down are also displayed as candidates that are unlikely to be effective for improvement, so that they remain selectable. When the user X selects one of the narrowed down improvement approaches, the CPU 21 displays the cause of the defect and the improvement measures associated with the selected improvement approach on the display unit 26 (P9). The user X implements the displayed improvement measures to improve the defect of the sewing device 3.

[0032] The code image display process executed in the sewing device 3 will be described with reference to FIG. 4. When a user turns on the power of the sewing device 3, the CPU 31 reads a program from the ROM 32 and starts the code image display process. The CPU 31 diagnoses various conditions, such as malfunctions, of the sewing device 3 based on the detection results of the various sensors 39 and the encoder 36B. Below, various conditions that may occur in the sewing device 3 will be described using malfunctions as an example. If no malfunction is detected (S1: NO) and no code image is displayed by user operation (S3: NO), the CPU 31 waits for processing. If a malfunction is detected (S1), the CPU 31 collects malfunction data that identifies the type of malfunction in the code image display process (S2), and then collects setting data that indicates the operating status of the sewing device 3 (S5). If the user performs an operation to display a code image (S1: NO, S3: YES), the CPU 31 does not collect malfunction data but collects setting data (S5).

[0033] The CPU 31 encodes the collected data (fault data and setting data, or setting data) to generate a code image Q (see FIG. 2) (S6). The CPU 31 displays the code image Q on the display unit 37 (S7) and returns the process to S1. Note that the code image Q will be hidden when the user operates the operation unit 38 to end the display of the code image Q, or when a predetermined time has elapsed.

[0034] 5 to 7, the sewing support process executed on the mobile terminal 2 will be described. When the user starts the sewing support app on the mobile terminal 2, the CPU 21 reads a program from the storage unit 24 and starts the sewing support process. As shown in FIG. 5, the CPU 21 starts the camera 28 and reads the code image Q (S11). When the code image Q is photographed by the user's operation, the CPU 21 decodes the code image Q and restores the defect data and setting data, or the setting data (S12). For convenience of explanation, the defect data and setting data, or the setting data obtained by decoding the code image Q, will be referred to as acquired data hereinafter.

[0035] Next, based on the model name and serial number included in the acquired data, it is determined whether the sewing device 3 to be supported is a device currently undergoing troubleshooting (S13). In the sewing support process, an improvement approach for an improvement corresponding to a problem that has occurred in the sewing device 3 is presented, and after the user has corrected the problem in accordance with the improvement approach, the acquired data is again acquired from the sewing device 3 to determine whether the improvement approach is effective. For convenience, the acquired data acquired when a problem occurs is referred to as first status data. When an improvement approach is presented by a process described below, the first status data is associated with the improvement approach and stored in the storage unit 24. For convenience, the acquired data acquired again after the improvement approach is presented is referred to as second status data. After it is determined whether the proposed improvement approach is effective for the first status data, the second status data is assigned an identifier indicating whether it is effective, and is stored together with the second status data in the storage unit 24.

[0036] Therefore, in S13, if the first status data including the model name and serial number and the improvement approach included in the acquired data are stored in the storage unit 24, the CPU 21 determines that the sewing device 3 to be supported is currently responding to a malfunction, i.e., is a device for which an improvement approach has been presented (S13: YES), and proceeds to S31 (see FIG. 7). On the other hand, if the first status data including the model name and serial number and the improvement approach included in the acquired data are not yet stored in the storage unit 24, the CPU 21 determines that the sewing device 3 to be supported is a device before the malfunction is addressed, i.e., is a device before the improvement approach has been presented (S13: NO), and stores the acquired data in the storage unit 24 as first status data (S14).

[0037] Next, the CPU 21 determines whether the first status data includes defect data (S16). If the sewing device 3 detects a defect, the first status data includes defect data (S16: YES) and the type of defect is known, so the CPU 21 proceeds to S19. The CPU 21 extracts multiple improvement approaches corresponding to the identified type of defect from the improvement approaches, arranges the extracted multiple improvement approaches in order of pre-ranked adaptability (see P6 in FIG. 3), and displays them on the display unit 26 (S19). If the defect is discovered by the user, the first status data does not include defect data (S16: NO). In this case, the CPU 21 displays a selection screen (see P5 in FIG. 3) for selecting the type of defect on the display unit 26 (S17). When the user selects the type of defect (S18), the CPU 21 extracts multiple improvement approaches corresponding to the selected type of defect from the improvement approaches, arranges the extracted multiple improvement approaches in order of pre-ranked adaptability (see P6 in FIG. 3), and displays them on the display unit 26 (S19).

[0038] As shown in FIG. 6, the user selects one improvement approach suitable for improving the defect from among a plurality of improvement approaches corresponding to the defect occurring in the sewing device 3, with reference to the application order (S21: NO, S26). Alternatively, the user operates the "ask an inquiry" button to narrow down the improvement approaches suitable for improving the defect (S21: YES). In this case, the CPU 21 displays an inquiry screen (see FIG. 3, P7) on the display unit 26 (S22) and accepts input of answers (S23). When the answers to the inquiry are input, the CPU 21 displays, as a narrowed-down result, improvement approaches that are previously associated with a combination of answers on the display unit 26 (S24). At this time, the CPU 21 displays the narrowed-down improvement approaches as candidates that may be effective for improvement, and displays the excluded improvement approaches as candidates that are less likely to be effective, so that both can be selected (see FIG. 3, P8).

[0039] The user selects one improvement approach suitable for improving the defect occurring in the sewing device 3, referring to the application ranking or the narrowed-down result of the medical interview (S26). The CPU 21 displays improvement measures corresponding to the selected improvement approach on the display unit 26 (S27, see FIG. 3, P9). The user attempts to improve the defect in accordance with the displayed improvement measures. Note that a "More Information" button may be provided on the display screen of the improvement measures. The "More Information" button is, for example, a link to an external site, and can connect to a video site or an explanation site showing specific steps of the improvement measures via a public line network. The CPU 21 stores the improvement approach selected in S26 and the type of defect selected in S18 or the type of defect included in the defect data in the memory unit 24 in association with the first status data stored in S28, and returns the process to S11.

[0040] After the user implements a remedy for the sewing device 3, the user resumes the sewing operation of the sewing device 3. If a problem occurs despite attempts to remedy the problem, the CPU 31 of the sewing device 3 generates a code image Q from the problem data and the setting data and displays it on the display unit 37. Alternatively, if the problem is resolved by attempting to remedy the problem, the CPU 31 continues the sewing operation. In this case, the CPU 31 generates a code image Q from the setting data in response to a user operation and displays it on the display unit 37. In the mobile terminal 2, the CPU 21 reads the code image Q (S11) and restores the acquired data (S12).

[0041] The CPU 21 determines that the sewing device 3 to be supported is currently undergoing troubleshooting (S13: YES) because the first status data including the model name and serial number included in the acquired data and the improvement approach are stored in the storage unit 24. As shown in Fig. 7, the CPU 21 stores the acquired data as second status data in the storage unit 24 (S31).

[0042] The CPU 21 compares the first status data and the second status data stored in the storage unit 24 (S32). For example, the CPU 21 compares the production volume included in the setting data of the first status data before the defect is corrected with the production volume included in the setting data of the second status data after the defect is corrected. If the production volume has increased, the CPU 21 determines that the defect has been corrected (S33: YES) and proceeds to S41. The CPU 21 assigns an identifier indicating that the defect has been corrected to the second status data in the storage unit 24 (S41). Next, the CPU 21 changes the improvement approach associated with the first status data to the first position in the application order corresponding to the current defect type, which is set for each defect type, and rearranges the application orders of the other improvement approaches in ascending order (S42). Therefore, if a similar defect occurs next time or later, the improvement approach that was effective in correcting the defect in the current sewing support process will be displayed at the top of the improvement approach selection screen displayed in S19. The CPU 21 then ends the sewing support process.

[0043] If it is determined in S33 that the second status data includes defect data or the production volume has not increased, the CPU 21 determines that the defect has not been improved (S33: NO), and proceeds to the process of S36. Since it may not be possible to determine the effectiveness of the defect improvement by comparing the acquired data alone, the CPU 21 receives an input from the user regarding whether the improvement approach associated with the first status data is effective (S36). If it is determined that the defect improvement is effective based on the user's operation (S37: YES), the CPU 21 proceeds to the process of S41, assigns an identifier indicating that the defect improvement is effective to the second status data (S41), changes the application ranking of the current improvement approach to first place (S42), and ends the sewing support process.

[0044] If the user determines that improving the defect is ineffective based on the user's operation (S37: NO), the CPU 21 assigns an identifier indicating that improving the defect is ineffective to the second status data in the storage unit 24 (S38). The CPU 21 displays a screen on the display unit 26 inquiring whether or not to continue improving the defect, and if the user instructs to end the process (S39: NO), the CPU 21 ends the sewing support process. On the other hand, if the user instructs to continue improving the defect (S39: YES), the CPU 21 returns the process to S24 and displays a screen for selecting an improvement approach (S24). The user can improve the defect using another improvement approach by selecting an improvement approach that was not selected in the initial process of S26.

[0045] Incidentally, the storage unit 24 of the portable terminal 2 stores first status data and the improvement approach therefor, and second status data and whether or not it was effective, as a history of how defects in the sewing device 3 have been dealt with. For example, when a new user is in charge of managing the sewing support system 1, the user may want to refer to the improvement approach taken by the previous user. As shown in FIG. 8, when a user operates the CPU 21 of the portable terminal 2 to display the defect improvement history, the CPU 21 reads a program from the storage unit 24 and starts a history display process.

[0046] The CPU 21 reads from the storage unit 24 the type of defect and the improvement approach associated with the first status data, and the presence or absence of an effect imparted to the second status data (S51). In this case, the CPU 21 also reads from the storage unit 24 information such as "date and time," "model name (type)," and "serial number" contained in the setting data of the first status data and the second status data. The CPU 21 arranges the read information in order of date and time and displays it as a list on the display unit 26 (S52). The display order of the information displayed as a list can be rearranged, for example, by model name (type) or the presence or absence of an effect. This allows the user to check the history of defect improvements made to the sewing device 3 using the mobile terminal 2.

[0047] As described above, when a malfunction or the like occurs in the sewing device 3, the mobile terminal 2 acquires data related to the malfunction as first status data, analyzes the type of the malfunction, and presents an improvement approach corresponding to the analysis result (type of malfunction) as a countermeasure. At this time, the mobile terminal 2 presents the countermeasure (corresponding improvement approach) according to a preset adaptation order. After the user addresses the malfunction according to the improvement approach, the mobile terminal 2 acquires the status of the sewing device 3 as second status data and compares it with the first status data. Based on the comparison result, the mobile terminal 2 changes the adaptation order of the improvement approach that was effective in addressing the malfunction. As a result, when a similar malfunction occurs next time or later, the mobile terminal 2 can present the previously effective improvement approach with a higher priority. By updating the adaptation order, the mobile terminal 2 can reduce the number of attempts the user needs to make to improve the malfunction the next time a malfunction occurs, thereby enabling the malfunction to be quickly fixed. Furthermore, by presenting highly effective improvement approaches with a higher priority, the mobile terminal 2 can make it easier for even a user who is unfamiliar with improving malfunctions to select an appropriate improvement approach.

[0048] The mobile terminal 2 can acquire the first status data and the second status data by capturing the code image Q displayed by the sewing device 3 and decoding the data. Compared to connecting to the sewing device 3 via a wired or wireless connection, for example, there is no need to connect to each sewing device 3 separately. Therefore, the mobile terminal 2 can acquire the first status data and the second status data from multiple types of sewing devices 3 and present an improvement approach suitable for each.

[0049] For example, if the sewing device 3 is unable to detect a defect that the user has found, the mobile terminal 2 can prompt the user to select a type of defect by presenting the type of defect. The user can then address the defect in accordance with the suggested improvement approach, allowing the mobile terminal 2 to promptly improve the defect.

[0050] The mobile terminal 2 can further narrow down the improvement approaches suitable for the content of the defect from a plurality of improvement approaches that include the cause of the defect that causes the type of defect selected by the user through an interview, thereby enabling quick and reliable improvement of the defect.

[0051] The mobile terminal 2 can display a list of improvement approaches for each type of defect, along with whether or not they were effective, as a history of previous attempts to improve defects in the sewing device 3. Therefore, the user can quickly improve the defect based on the history.

[0052] In the above description, the CPU 21, ROM 22, and RAM 23 are examples of the "portable computer" of the present invention. The CPU 21 of the portable terminal 2 that executes the processes of S11, S12, and S14 is an example of the "first acquisition step" of the present invention.

[0055] The present invention is not limited to the above-described embodiment, and various modifications can be made. The mobile terminal 2 is not limited to a smartphone, a tablet terminal, or the like, but may be, for example, a notebook PC or a terminal device assembled specifically for the sewing support system 1. The code image Q is not limited to a two-dimensional barcode, but may be a one-dimensional barcode, or an encoded code may be converted into a character string or the like and displayed. Alternatively, a dedicated code image may be used instead of a general-purpose one.

[0056] An improvement approach that has been effective in improving a defect is changed to the first place in the adaptation ranking, but the adaptation ranking may be weighted according to the number of times that an improvement approach that has been effective in improving a defect in the past, so that an improvement approach that has been effective in improving a defect not only last time but also in the past may be ranked higher.

[0057] Furthermore, an improvement approach that has been assigned an identifier indicating that it is ineffective may be moved down in the application order, changed from a potentially effective candidate to a candidate that is less likely to be effective, or moved to the bottom of the display order. Alternatively, an improvement approach that has been assigned an identifier indicating that it is ineffective may be changed so that it is not displayed for a certain period of time.

[0058] Alternatively, the application order may be changed taking into consideration both the effectiveness and ineffectiveness of the improvement approaches in improving the defect. For example, the application order may be weighted according to the proportion of the number of times an approach was effective among the number of times it was selected in the past.

[0059] Also, if improvement approaches based on the adaptation order are presented, it is not necessary to narrow down the improvement approaches through a medical interview. Also, when a selection screen for selecting the type of defect is displayed (see P5 in FIG. 3), it is possible to display only expected defects based on the setting data included in the first status data, for example, the type and thickness of the sewing material, the sewing speed, or the output of the sensor 39 or the encoder 36B during sewing operation, or to display them in order of likelihood.
