[0001] The present disclosure relates to a maintenance schedule management system, a maintenance schedule management device, a control method, and a control program. [Background technology]

[0002] Conventionally, maintenance work for an apparatus has been performed based on a maintenance schedule created based on numerical values ​​such as the time the apparatus is used, the number of times, and the interval period from the previous maintenance work, thereby maintaining the soundness of the apparatus. Note that maintenance work for an apparatus is not necessarily performed by an end user who uses the apparatus to carry out production, but may also be periodically performed by, for example, an apparatus manufacturer that manufactures the apparatus. Therefore, conventional maintenance schedules have been managed independently by end users or apparatus manufacturers.

[0003] Patent Document 1 discloses a maintenance management system that can monitor the health of large-scale facilities and manage an overall maintenance schedule. In Patent Document 1, a maintenance management device owned by an administrator of the maintenance management system generates a repair schedule for each facility, and an item management device owned by a warehouse manager and a resource management device owned by a resource manager are given access rights to the maintenance management device in advance. In Patent Document 1, when the maintenance management device inquires of the item management device about components necessary for repairing each facility, the item management device generates and transmits a supply schedule for the components, and calculates the number of man-hours for the repair based on the supply schedule received by the maintenance management device. Also, in Patent Document 1, when the maintenance management device conducts a bid according to the calculated number of man-hours and presents procurement information to the resource management device, the resource management device generates and transmits a supply schedule for resources such as human resources and material resources necessary for the repair.

However, in the maintenance management system disclosed in Patent Document 1, although the item management device and the resource management device are given access rights to the maintenance management device, the repair schedules generated and managed by the maintenance management device cannot be changed from these devices. For this reason, in the maintenance management system disclosed in Patent Document 1, there is a problem that even if there is a recommended schedule that contributes highly to maintaining the soundness of each piece of equipment, the warehouse manager and the resource manager cannot directly reflect the recommended schedule in the repair schedule.

[0006] The present disclosure has been made in consideration of the above-mentioned circumstances, and aims to make it easier to use managed maintenance schedules. [Means for solving the problem]

[0007] In order to achieve the above object, the maintenance schedule management system according to the present disclosure is a maintenance schedule management system that manages a maintenance schedule of a maintenance target device, which is a device to be maintained, and includes a maintenance schedule management device used by an administrator of the maintenance schedule management system, and a user terminal used by a user of the maintenance schedule management system. The user terminal includes an end user terminal used by an end user who is a user of the maintenance target device, and an equipment manufacturer terminal used by an equipment manufacturer who is a manufacturer of the maintenance target device. The maintenance schedule management device includes an authority granting unit that grants the end user authority to set maintenance information, which is information related to the maintenance of the maintenance target device, in the maintenance schedule within a predetermined limit to the end user terminal, and grants the equipment manufacturer authority to set the maintenance information to the equipment manufacturer terminal within a predetermined limit, and a maintenance information setting unit that is capable of setting maintenance information in the maintenance schedule based on information output from the end user terminal and the authority granted to the end user terminal, and is capable of setting maintenance information in the maintenance schedule based on information output from the equipment manufacturer terminal and the authority granted to the equipment manufacturer terminal. The device manufacturer terminal can use the security information set by the end user terminal based on the authority given to the device manufacturer terminal, and the end user terminal can use the security information set by the device manufacturer terminal based on the authority given to the device manufacturer terminal, the authority given to the end user terminal is the primary authority and the authority given to the device manufacturer terminal is the secondary authority. The maintenance information setting unit starts setting of maintenance information including a scheduled date and time of maintenance work calculated based on periodic maintenance information, which is information on maintenance for each predetermined period, and then compares a history of scheduled dates and times calculated based on state maintenance information, which is information on maintenance when the state of the maintenance target device deteriorates, with a history of scheduled dates and times calculated based on the periodic maintenance information. If it determines that the accuracy of judging deterioration of the state of the maintenance target device exceeds a predetermined standard, the maintenance information setting unit switches from setting of maintenance information based on periodic maintenance information to setting of maintenance information based on state maintenance information. . Effect of the Invention

[0008] According to the present disclosure, the end user terminal and the device manufacturer terminal can set and use maintenance information in the maintenance schedule within a limit that is predetermined for each user, by the authority given by the maintenance schedule management device. As a result, the maintenance schedule management system according to the present disclosure makes it easier to use the managed maintenance schedule than a maintenance schedule management system that does not have the above-mentioned configuration.

[0032] The user terminal 200 is capable of displaying an editing screen for consumable part related information (not shown) and outputting information inputted into the editing screen by a user operating the user terminal 200 to the maintenance schedule management device 100. Therefore, the maintenance schedule management device 100 is capable of generating consumable part related information based on the output information acquired by the user side information acquisition unit 130 from the user terminal 200 and storing the information in the consumable part related information storage unit 115.

[0033] Returning to FIG. 2, the status maintenance information generating unit 125 generates status maintenance information based on information on the status of the maintenance target device 10 acquired by the device side information acquiring unit 120 from the edge terminal 20. The status maintenance information is information capable of identifying a timing for performing maintenance work based on the diagnosis result of the status of each of the maintenance target devices 11 to 19 automatically generated by the maintenance schedule management device 100. For example, the status maintenance information generating unit 125 calculates the replacement timing of each consumable part based on the operation time of the maintenance target device 10 identified from the above-mentioned information, and generates information indicating the calculated replacement timing as the status maintenance information. In addition, the status maintenance information generating unit 125 generates status maintenance information including, for example, consumable part status information indicating the wear rate of the consumable part of the maintenance target device 10 and predictive maintenance information which is information used to predict whether or not maintenance is necessary based on the difference between the current state and the normal state of the maintenance target device 10. That is, the status maintenance information includes information such as information indicating the replacement timing of each consumable part, consumable part status information, and predictive maintenance information.

[0034] The maintenance information setting unit 140 sets the maintenance information in the maintenance schedule. The maintenance information setting unit 140 can set the maintenance information based on the output information acquired by the user side information acquisition unit 130 from the user terminal 200. Here, the maintenance information is information capable of identifying a maintenance task as a maintenance work. The maintenance information includes, for example, information indicating the maintenance target device 10 on which the maintenance work is performed and its consumable parts, scheduled maintenance date and time information indicating the scheduled maintenance date and time which is the scheduled date and time for performing the maintenance work, and information indicating the content of the maintenance work, and is information that can be displayed in a list format in a table for each maintenance task of the maintenance target devices 11 to 19, as in the maintenance information list display screen 450 shown in FIG. 6.

[0035] 6, the maintenance information includes information corresponding to items such as a "task name" indicating the name of a maintenance task, a "type" indicating the type of consumable parts of the maintenance target devices 11 to 19, a "criteria" indicating the criteria for setting the maintenance task, and a "manual" indicating the save destination of a manual document file in which the contents of the maintenance task are described. Therefore, as shown in FIG. 6, the maintenance information is information that can identify, for example, the "task name" for the consumable parts of the first maintenance target device 11 as "cleaning XYZ", "type" as "standard", and "criteria" as "time".

[0036] 7A to 7D, and outputs information input to the editing screen 500 by a user's operation of the user terminal 200 to the maintenance schedule management device 100. Therefore, the maintenance information setting unit 140 can generate and set maintenance information based on the output information acquired by the user-side information acquisition unit 130 from the user terminal 200.

[0037] Specifically, first, the user terminal 200 displays a list display screen 300 of maintenance target device related information shown in Fig. 4, and the user selects one of the maintenance target devices 11 to 19 displayed in the list by inputting information into the list display screen 300 by the user. Next, the user terminal 200 displays a list display screen 400 of consumable part related information shown in Fig. 5, and the user selects one of the consumable parts displayed in the list by inputting information into the list display screen 400 by the user. Note that if a consumable part is necessary for the maintenance work, it should be selected, and if not, it is not necessary to select it.

[0038] Next, the user terminal 200 displays a maintenance information editing screen 500 shown in Fig. 7A. As shown in Fig. 7A, the maintenance information editing screen 500 is provided, from the top, with a task name input field 510 which is an input field for information corresponding to the "task name", a reference input field 520 which is an input field for information corresponding to the "reference", and a manual input field 530 for inputting information corresponding to the "manual" item. The maintenance information editing screen 500 is also provided with a save button 540 below the manual input field 530 for outputting the input information and storing it in the maintenance schedule management device 100, and a cancel button 550 to the right of the save button 540 for erasing the input information without storing it in the maintenance schedule management device 100.

[0039] Furthermore, the criteria input field 520 includes, as information corresponding to the "criteria" item, a number of times selection radio button 521 for selecting "number of times", a time selection radio button 522 for selecting "time", a period selection radio button 523 for selecting "period", and a diagnosis result selection radio button 524 for selecting "diagnosis result".

[0040] 7A to 7D, the reference input field 520 changes the input field for detailed information depending on which of the radio buttons 521 to 524 is selected. For example, as shown in FIG. 7A, the reference input field 520 displays a number of times input field 525, which is a display field for inputting detailed information corresponding to the item "number of times", when the number of times selection radio button 521 is selected. For example, as shown in FIG. 7B, the reference input field 520 displays a time input field 526, which is a display field for inputting detailed information corresponding to the item "time", when the time selection radio button 522 is selected. For example, as shown in FIG. 7C, the reference input field 520 displays a period input field 527, which is a display field for inputting detailed information corresponding to the item "period", when the period selection radio button 523 is selected. For example, as shown in FIG. 7D, the reference input field 520 displays a diagnosis result input field 528, which is a display field for inputting detailed information corresponding to the item "diagnosis result", when the diagnosis result selection radio button 524 is selected.

[0041] 2, the user terminal 200 displays information corresponding to the items of "Task Name," "Standard," and "Manual" according to input by the user to the editing screen 500 of the maintenance information, and outputs the information displayed on the editing screen 500 and the information selected on the list display screens 300, 400 to the maintenance schedule management device 100 when the save button 540 is operated. Therefore, the maintenance information setting unit 140 can generate maintenance information or update already generated maintenance information based on the output information acquired by the user-side information acquisition unit 130 from the user terminal 200.

[0042] First, the maintenance information setting unit 140 generates periodic maintenance information, which is information on maintenance for each predetermined period, based on the output information acquired from the user terminal 200. Specifically, when the information corresponding to the item of "criteria" is any one of "number of times," "time," and "cycle," the maintenance information setting unit 140 generates this information as periodic maintenance information. Therefore, in this embodiment, the periodic maintenance information is information that can identify the opportunity to perform maintenance work, such as the number of times of operation, operation time, and maintenance cycle of each maintenance target device 11 to 19, which are artificially determined by the user. In addition, when the maintenance information setting unit 140 generates periodic maintenance information, the maintenance information setting unit 140 generates scheduled maintenance date and time information based on the periodic maintenance information. For example, if the periodic maintenance information is information indicating that maintenance work will be performed when the operation time of the first maintenance target device 11 exceeds 500 hours, the maintenance information setting unit 140 calculates the date and time 500 hours after the first maintenance target device 11 is operated, and generates scheduled maintenance date and time information indicating the calculated date and time.

[0043] On the other hand, when the information corresponding to the item of "criteria" is "diagnosis result", the maintenance information setting unit 140 generates scheduled maintenance date and time information based on the status maintenance information generated by the status maintenance information generating unit 125. For example, if the replacement time of the consumable part of the first maintenance target device 11 specified from the status maintenance information is 100 hours later, the maintenance information setting unit 140 calculates the date and time 100 hours later and generates scheduled maintenance date and time information indicating the calculated date and time.

[0044] Then, the maintenance information setting unit 140 sets the scheduled maintenance date and time indicated by the generated scheduled maintenance date and time information in the maintenance schedule, thereby setting the maintenance information including the scheduled maintenance date and time information in the maintenance schedule.

[0045] The maintenance information setting unit 140 can switch the information on which the scheduled maintenance date and time information is generated and set from the periodic maintenance information to the status maintenance information. Specifically, the maintenance information setting unit 140 first compares the history of the scheduled maintenance date and time information set based on the periodic maintenance information with the history of the status of the maintenance target device 10 identified from the status maintenance information. Then, when the maintenance information setting unit 140 determines from the comparison result that the accuracy of judging the deterioration of the status of the maintenance target device 10 identified from the status maintenance information exceeds a predetermined standard, it switches from generating and setting the scheduled maintenance date and time information based on the periodic maintenance information to generating and setting the scheduled maintenance date and time information based on the status maintenance information.

[0046] The authority granting unit 150 grants the user terminal 200 the authority to set maintenance information in the maintenance schedule within a limit that is predetermined for each user. For example, the authority granting unit 150 grants the equipment manufacturer terminal 201 the authority to set maintenance information in the maintenance schedule within the limit of the maintenance target device 10 that the equipment manufacturer sold to the end user. Also, for example, the authority granting unit 150 grants the end user terminal 202 the authority to set maintenance information in the maintenance schedule within the limit of the maintenance target device 10 owned by the end user. Therefore, the maintenance information setting unit 140 is able to set maintenance information in the maintenance schedule based on the information acquired from the user terminal 200 and the authority granted to the user terminal 200.

[0047] In this embodiment, the authorization unit 150 can specify a predetermined restriction for each user based on user information, which is information related to the user, acquired in advance from the user terminal 200. For example, the authorization unit 150 can specify the maintenance target device 10 sold to the end user by the equipment manufacturer from the user information acquired from the equipment manufacturer terminal 201, and specify the maintenance target device 10 owned by the end user from the end user terminal 202.

[0048] In addition, the authority given to the equipment manufacturer terminal 201 and the authority given to the end user terminal 202 may overlap in part. For example, consider a case where the first end user owns devices a, d, e, and h in factory A, and devices b, c, f, and g in factory B. In this case, as shown in the frame surrounded by the dashed line in FIG. 8, the first equipment manufacturer may sell devices a, b, c, and d to the first end user. Therefore, in this case, the authority given to the equipment manufacturer terminal 201 used by the first equipment manufacturer and the authority given to the end user terminal 202 used by the first end user overlap in the part where maintenance information can be set in the maintenance schedule for the devices a, b, c, and d.

[0049] Returning to FIG. 2, the authority granting unit 150 may grant the user terminal 200 authority to store the maintenance target device related information in the maintenance target device related information storage unit 110 and authority to store the consumable part related information in the consumable part related information storage unit 115 within a limit that is predetermined for each user. For example, the authority granting unit 150 may grant the equipment manufacturer terminal 201 authority to store the maintenance target device related information and the consumable part related information within the limit of the maintenance target device 10 sold by the equipment manufacturer to the end user. Also, for example, the authority granting unit 150 may grant the end user terminal 202 authority to store the maintenance target device related information and the consumable part related information within the limit of the maintenance target device 10 owned by the end user. In this way, the maintenance schedule management device 100 can store the maintenance target device related information and the consumable part related information based on the information acquired from the user terminal 200 and the authority granted to the user terminal 200.

[0050] The list display information generating unit 161 generates list display information necessary for displaying at least the maintenance information, the consumable parts status information, and the predictive maintenance information in a list. Note that the list display information generating unit 161 may generate list display information including not only these pieces of information but also information necessary for displaying in a list, for example, information indicating the operation status of the maintenance target device 10, information indicating the operation rate of the maintenance target device 10, and information indicating the diagnostic score of the maintenance target device 10 specified by the status maintenance information.

[0051] The list display information output unit 162 outputs the list display information generated by the list display information generation unit 161 to the user terminal 200. The list display information output unit 162 outputs the list display information based on the authority granted to the user terminal 200 by the authority granting unit 150. For example, the list display information output unit 162 outputs list display information related to the maintenance target device 10 sold to the end user by the equipment manufacturer to the equipment manufacturer terminal 201, while outputting list display information related to the maintenance target device 10 owned by the end user to the end user terminal 202.

[0052] Therefore, the user terminal 200 is capable of displaying the list display information acquired from the maintenance schedule management device 100. For example, as shown in FIG. 9, the user terminal 200 is capable of displaying a list of information included in the acquired list display information on a so-called dashboard screen 600 that tracks, analyzes, and displays information required for managing a maintenance schedule. In this embodiment, the dashboard screen 600 displays information included in the list display information as a widget screen. Thus, the dashboard screen 600 displays a list of a maintenance information screen 610 that is a widget screen based on maintenance information, a consumable parts status information screen 620 that is a widget screen based on consumable parts status information, and a predictive maintenance information screen 630 that is a widget screen based on predictive maintenance information. The dashboard screen 600 allows the user to perform various display changes, such as deciding whether to display or hide each screen displayed in a list and rearranging the screens, by operating the user terminal 200.

[0053] Returning to FIG. 2, the maintenance schedule information generating unit 171 generates maintenance schedule information indicating the maintenance schedule in which the maintenance information is set, and the maintenance schedule information output unit 172 outputs the maintenance schedule information generated by the maintenance schedule information generating unit 171. Thus, the user terminal 200 is capable of displaying the maintenance schedule information acquired from the maintenance schedule management device 100. For example, as shown in FIG. 10, it is possible to display a maintenance calendar screen 700 that displays a list of maintenance information set in the maintenance schedule in the form of a calendar. The maintenance calendar screen 700 is a screen on which an image is displayed indicating that maintenance information with a "task name" of "Task1" is set on "Monday, August 1, 2022", for example. Note that the maintenance calendar screen 700 allows the user to perform various display changes, such as deciding whether to display or hide the maintenance information displayed by an operation using the user terminal 200, and rearranging the displayed maintenance information.

[0054] Returning to FIG. 2, when a maintenance task identifiable by the maintenance information is completed, the maintenance status information generating unit 173 generates maintenance status information that can identify that the maintenance task has been completed. For example, when the user-side information acquiring unit 130 acquires information indicating that the maintenance task has been completed from the user terminal 200, the maintenance status information generating unit 173 generates maintenance status information that can identify that the maintenance task has been completed. The maintenance status information generating unit 173 can generate maintenance status information including first maintenance status information that can identify the status of the first maintenance task that can be identified by the first maintenance information of the maintenance information, and second maintenance status information that can identify the status of the second maintenance task that can be identified by the second maintenance information of the maintenance information. The maintenance status information is, for example, information that can identify whether the status of the first maintenance task and the status of the second maintenance task are "scheduled to be performed", "being performed", or "performed".

[0055] The maintenance status information output unit 174 outputs the maintenance status information to the user terminal 200. The maintenance status information output unit 174 outputs the maintenance status information based on the authority granted to the user terminal 200 by the authority granting unit 150. For example, the maintenance status information output unit 174 outputs, to the equipment manufacturer terminal 201, maintenance status information on the maintained target device 10 sold to the end user by the equipment manufacturer, and outputs, to the end user terminal 202, maintenance status information on the maintained target device 10 owned by the end user.

[0056] Therefore, the user terminal 200 is capable of displaying the maintenance status information acquired from the maintenance schedule management device 100. For example, as shown in FIG. 11, the user terminal 200 is capable of displaying a list of information included in the acquired maintenance status information on a maintenance status list screen 750 that displays a list of the statuses of the maintenance work. The maintenance status list screen 750 includes a scheduled work column 751 that displays a list of maintenance work whose work status is "scheduled", a currently performed work column 752 that displays a list of maintenance work whose work status is "in progress", and a completed work column 753 that displays a list of maintenance work whose work status is "completed". Therefore, the maintenance status list screen 750 displays a list of whether the status of the maintenance work, such as the first maintenance that can be specified by the first maintenance information and the second maintenance that can be specified by the second maintenance information, is "scheduled", "in progress", or "completed". Note that the maintenance status list screen 750 allows the user to perform various display changes, such as deciding whether to display or not display the displayed maintenance status information and rearranging the displayed maintenance status information, by operating the user terminal 200.

[0057] For example, on the maintenance status list screen 750, a list of maintenance information whose "task name" is "TaskA," "TaskB," and "TaskC" is displayed in a scheduled work column 751. Also, on the maintenance status list screen 750, a list of maintenance information whose "task name" is "TaskD," "TaskE," and "TaskF" is displayed in a work in progress column 752. And on the maintenance status list screen 750, a list of maintenance information whose "task name" is "TaskG," "TaskH," "TaskI," and "TaskJ" is displayed in a completed work column 753.

[0058] 2, the maintenance schedule information storage unit 175 stores maintenance schedule information indicating a maintenance schedule in which maintenance information is set. The maintenance schedule information storage unit 175 stores the maintenance information set in the maintenance schedule in association with maintenance status information indicating the status of maintenance work that can be specified by the maintenance information.

[0059] The notification information generating unit 176 generates notification information based on a situation that can be specified by the maintenance status information, and the notification information output unit 177 outputs the notification information generated by the notification information generating unit 176 to the user terminal 200. Thus, based on the notification information acquired from the maintenance schedule management device 100, the user terminal 200 is capable of, for example, displaying a notification screen, displaying a notification message, or outputting a notification sound, although not shown in the figure.

[0060] (Regarding the maintenance information setting process according to the embodiment) Next, a flowchart will be used to explain the operation of the maintenance schedule management device 100 to set maintenance information in a maintenance schedule and output the maintenance schedule information to the user terminal 200. When the maintenance schedule management device 100 starts transmitting and receiving information to the user terminal 200, it starts executing the maintenance information setting process shown in Fig. 12. First, the authority granting unit 150 grants the user terminal 200 the authority to set maintenance information in the maintenance schedule within a limit predetermined for each user (step S101).

[0061] After the right is granted, the user-side information acquisition unit 130 acquires information output based on information input by the user terminal 200 to the list display screen 300 of the maintenance target device related information shown in FIG. 4, the list display screen 400 of the consumable part related information shown in FIG. 5, and the maintenance information editing screen 500 shown in FIG. 7A to FIG. 7D (step S102). After acquiring the information, the maintenance information setting unit 140 judges whether the information corresponding to the item of "criteria" included in the acquired information is any of "number of times", "time", and "cycle" (step S103). If the information corresponding to the item of "criteria" is "number of times", "time", and "cycle" (step S103; Y), the maintenance information setting unit 140 generates regular maintenance information from the acquired information (step S104), and generates scheduled maintenance date and time information based on the generated regular maintenance information (step S105).

[0062] On the other hand, when the information corresponding to the "criteria" item included in the acquired information is "diagnosis result" (step S103; N), the maintenance information setting unit 140 generates scheduled maintenance date and time information based on the status maintenance information previously generated by the status maintenance information generating unit 125 (step S106). After generating the scheduled maintenance date and time information, the maintenance information setting unit 140 sets the scheduled maintenance date and time indicated by the generated scheduled maintenance date and time information in the maintenance schedule, thereby setting the maintenance information including the scheduled maintenance date and time information in the maintenance schedule (step S107), and ends the process.

[0063] As described above, according to the maintenance schedule management system 1 of the present embodiment, in the maintenance schedule management device 100, the authority granting unit 150 grants the user terminal 200 the authority to set maintenance information related to the maintenance of the maintenance target device 10 in the maintenance schedule within a limit that is predetermined for each user. Specifically, the authority granting unit 150 grants authority to the end user terminal 202 within a limit that is predetermined for the end user, and grants authority to the equipment manufacturer terminal 201 within a limit that is predetermined for the equipment manufacturer. In addition, in the maintenance schedule management device 100, the maintenance information setting unit 140 sets maintenance information in the maintenance schedule based on the information output from the user terminal 200 and the authority granted to the user terminal 200. Specifically, security information setting unit 140 can set security information based on information output from end user terminal 202 and authority granted to end user terminal 202, and can set security information based on information output from equipment manufacturer terminal 201 and authority granted to equipment manufacturer terminal 201. Then, equipment manufacturer terminal 201 can use the security information set by end user terminal 202 based on the authority granted to it, and end user terminal 202 can use the security information set by equipment manufacturer terminal 201 based on the authority granted to it.

[0064] In this way, the equipment manufacturer terminal 201 and the end user terminal 202 can set and use maintenance information in the maintenance schedule within a limit predetermined for the user, with the authority granted by the maintenance schedule management device 100. As a result, the maintenance schedule management system 1 according to this embodiment makes it easier to use the maintenance schedule it manages than a maintenance schedule management system that does not have the above-mentioned configuration.

[0065] The device manufacturer terminal 201 may be allowed to use the security information set by the end user terminal 202 within a predetermined limit. That is, the end user terminal 202 may have the primary authority for use of the security information set by the end user terminal 202, while the device manufacturer terminal 201 may have the secondary authority. Similarly, the device manufacturer terminal 201 may have the primary authority for use of the security information set by the device manufacturer terminal 201, while the end user terminal 202 may have the secondary authority, and the use by the end user terminal 202 may be restricted.

[0066] In this embodiment, since the equipment manufacturer terminal 201 and the end user terminal 202 access the maintenance schedule management device 100 and freely set and use maintenance information in the maintenance schedule, it is necessary to enable each user to efficiently use information related to the management of the maintenance schedule. For this reason, the maintenance schedule management system 1 according to this embodiment improves the visibility of information related to the management of the maintenance schedule by enabling the users who use the equipment manufacturer terminal 201 and the end user terminal 202 to freely edit the screens and information displayed on each screen shown in Fig. 9 to Fig. 11.

[0067] According to the maintenance schedule management system 1 of this embodiment, in the maintenance schedule management device 100, the maintenance status information generating unit 125 generates maintenance status information including consumable part status information and predictive maintenance information. In addition, in the maintenance schedule management device 100, the list display information generating unit 161 generates at least information required for displaying a list of the maintenance information, the consumable part status information, and the predictive maintenance information as list display information required for displaying a list of information used to manage the maintenance schedule, and the list display information output unit 162 outputs the generated list display information.

[0068] In this way, in the maintenance schedule management system 1 according to this embodiment, the user terminal 200 can display a list of a maintenance information screen 610, a consumable parts status information screen 620, and a predictive maintenance information screen 630, which are widget screens, on a dashboard screen 600 shown in Fig. 9. As a result, in the maintenance schedule management system 1 according to this embodiment, the user can adjust the maintenance schedule according to the user's situation while checking the maintenance information, the consumable parts status information, and the predictive maintenance information related to the maintenance target device 10.

[0069] That is, in the maintenance schedule management system 1 according to the present embodiment, the user can obtain all the information necessary for managing the maintenance schedule and display it as a list on the dashboard screen 600 as a widget screen, while setting the maintenance information and changing the settings by himself / herself. Therefore, the user is not forced to perform maintenance work more than necessary, and can perform maintenance work according to individual circumstances such as being busy with work. In addition, the user can freely edit each widget screen displayed on the dashboard screen 600 to improve the viewability of the displayed information and efficiently use the information.

[0070] Furthermore, according to the maintenance schedule management system 1 of the present embodiment, the maintenance information includes scheduled maintenance date and time information indicating the scheduled maintenance date and time when the maintenance work on the maintenance target device 10 is scheduled to be performed. By doing this, in the maintenance schedule management system 1 of this embodiment, the maintenance information setting unit 140 can set maintenance information including the planned maintenance date and time information to the maintenance schedule by setting the planned maintenance date and time indicated by the planned maintenance date and time information to the maintenance schedule.

[0071] In particular, according to the maintenance schedule management system 1 of this embodiment, the maintenance information setting unit 140 sets, in the maintenance schedule, scheduled maintenance date and time information indicating a date and time calculated based on periodic maintenance information, which is information regarding maintenance for each predetermined period, or status maintenance information, which is information regarding maintenance when the status of the maintenance target device deteriorates.

[0072] In this way, in the maintenance schedule management system 1 according to this embodiment, the maintenance information setting unit 140 can set, for example, periodic maintenance information manually determined by a user, or maintenance information including scheduled maintenance date and time information generated using status maintenance information automatically generated by the maintenance schedule management device 100, in the maintenance schedule. Note that, in this embodiment, the status maintenance information is information automatically generated by the maintenance schedule management device 100, but it may be information manually determined by a user similar to the periodic maintenance information.

[0073] Furthermore, according to the maintenance schedule management system 1 of this embodiment, the maintenance information setting unit 140 switches from setting scheduled maintenance date and time information based on regular maintenance information to setting scheduled maintenance date and time information based on status maintenance information based on the result of comparing the history of scheduled maintenance date and time information set based on regular maintenance information with the history of the status of the maintenance target device 10 identified from the status maintenance information.

[0074] In this way, the maintenance schedule management system 1 according to this embodiment can switch from setting a maintenance schedule based on periodic maintenance information artificially determined by a user to setting a maintenance schedule based on status maintenance information automatically generated by the maintenance schedule management device 100. As a result, the maintenance schedule management system 1 according to this embodiment can reduce the workload of a user who adjusts the setting of periodic maintenance information compared to a maintenance schedule management system that cannot switch from setting scheduled maintenance date and time information based on periodic maintenance information to setting scheduled maintenance date and time information based on status maintenance information.

[0075] Moreover, according to the maintenance schedule management system 1 of this embodiment, the maintenance target devices 10 include a first maintenance target device 11, a second maintenance target device 12, ..., a ninth maintenance target device 19. In the maintenance schedule management device 100, the maintenance information setting unit 140 can set each piece of maintenance information from the maintenance information of the first maintenance target device 11 to the maintenance information of the ninth maintenance target device 19 in the maintenance schedule. In this way, the maintenance schedule management system 1 of this embodiment can manage maintenance work for multiple types of maintenance target devices 10 in one maintenance schedule, and the user can check maintenance information for multiple types of maintenance target devices 10 in one maintenance schedule.

[0076] Furthermore, according to the maintenance schedule management system 1 of this embodiment, in the maintenance schedule management device 100, the maintenance status information generation unit 173 generates maintenance status information capable of identifying the status of maintenance work that can be identified by the maintenance information. Then, in the maintenance schedule management device 100, the maintenance status information output unit 174 outputs the generated maintenance status information to the user terminal 200. In this way, in the maintenance schedule management system 1 according to this embodiment, the user terminal 200 can display a list of information included in the acquired maintenance status information on, for example, a maintenance status list screen 750 shown in Fig. 11. As a result, in the maintenance schedule management system 1 according to this embodiment, the user can check the maintenance information displayed on the maintenance status list screen 750 and check the status of the maintenance work specified by the maintenance information. In addition, the user can freely edit the information displayed on the maintenance status list screen 750 to improve the viewability of the information and use the information efficiently.

[0077] Furthermore, according to the maintenance schedule management system 1 of this embodiment, in the maintenance schedule management device 100, the maintenance status information generation unit 173 generates maintenance status information capable of identifying that the status of the maintenance work has been performed when the maintenance work is completed. In the maintenance schedule management device 100, the maintenance schedule information storage unit 175 as an example of an information storage unit stores the maintenance information in association with the maintenance status information indicating the status of the maintenance work that can be identified by the maintenance information. In this way, the maintenance schedule management system 1 of this embodiment can manage the content of the maintenance for the maintenance target device 10 in a linked state with the results of the maintenance when the maintenance work is completed.

[0078] Moreover, according to the maintenance schedule management system 1 of this embodiment, the maintenance schedule management device 100 has a maintenance status information generating unit 173 that generates maintenance status information including first maintenance status information that can identify the status of the first maintenance work that can be identified by the first maintenance information, and second maintenance status information that can identify the status of the second maintenance work that can be identified by the second maintenance information. Also, in the maintenance schedule management device 100, the maintenance status information output unit 174 outputs maintenance status information including the first maintenance status information and the second maintenance status information to the user terminal 200. The maintenance status information is information that can identify whether the status of the first maintenance work and the status of the second maintenance work are "scheduled to be performed", "in progress", or "completed".

[0079] In this way, in the maintenance schedule management system 1 according to this embodiment, the user terminal 200 can display a list of each piece of maintenance information in, for example, a scheduled work column 751, a work in progress column 752, and a completed work column 753 of a maintenance status list screen 750 shown in Fig. 11. As a result, in the maintenance schedule management system 1 according to this embodiment, the user can check the maintenance status list screen 750 to see whether the status of the maintenance work identified by each piece of maintenance information is "scheduled to be performed," "in progress," or "completed."

[0080] Furthermore, according to the maintenance schedule management system 1 of this embodiment, in the maintenance schedule management device 100, the notification information output unit 177 outputs to the user terminal 200 notification information indicating a notification based on a situation that can be identified by the maintenance status information. By doing this, in the maintenance schedule management system 1 of this embodiment, the maintenance schedule management device 100 can output alarm information regarding maintenance based on the status of maintenance work, and the user terminal 200 can display the alarm information and output alarm sounds.

[0081] [Embodiment 2] In the first embodiment, the periodic maintenance information is information manually determined by the user, but it may be information automatically generated by the maintenance schedule management device 100, similar to the status maintenance information. The maintenance schedule management system 1 according to the second embodiment will be described in detail below with reference to Figs. 13 and 14. In the second embodiment, the configuration different from that of the first embodiment will be described, and the description of the same configuration as that of the first embodiment will be omitted because it is redundant.

[0082] (Regarding the maintenance schedule management device 100 according to the second embodiment) As shown in Figure 13, in the maintenance schedule management system 1 of this embodiment 2, the maintenance schedule management device 100 further includes a periodic maintenance information generation unit 181 that generates periodic maintenance information, and a status maintenance information output unit 182 that outputs status maintenance information.

[0083] (Hardware Configuration of the Maintenance Schedule Management Device 100 According to the Second Embodiment) In this embodiment, the control unit 51 shown in Fig. 3 functions as a periodic maintenance information generating unit 181 shown in Fig. 13 in accordance with the control program 59. Also, the transmission / reception unit 56 shown in Fig. 3 functions as a status maintenance information output unit 182 shown in Fig. 13. The maintenance schedule management device 100 realizes the functions of the periodic maintenance information generating unit 181 and the status maintenance information output unit 182 shown in Fig. 13 by the control unit 51 using the main storage unit 52, the external storage unit 53, and the transmission / reception unit 56 as resources. For example, the maintenance schedule management device 100 executes a periodic maintenance information generating step performed by the periodic maintenance information generating unit 181 and a status maintenance information output step performed by the status maintenance information output unit 182.

[0084] (Details of Functional Configuration of Maintenance Schedule Management Apparatus 100 According to Second Embodiment) 13, the periodic maintenance information generating unit 181 generates periodic maintenance information based on the history of scheduled maintenance date and time information set based on the status maintenance information. For example, when the number of times scheduled maintenance date and time information has been set based on the status maintenance information exceeds a predetermined threshold, the periodic maintenance information generating unit 181 generates periodic maintenance information that can specify that the average value of the interval between scheduled maintenance dates and times specified from each scheduled maintenance date and time information is set as the cycle of maintenance work.

[0085] The status maintenance information generating unit 125 calculates the wear rate of each consumable part and the replacement time of each consumable part based on, for example, the operating time of the maintenance target device 10, and generates information indicating the calculated wear rate, replacement time, and replacement work history of each consumable part as consumable part status information. Therefore, the consumable part status information includes, for example, first consumable part status information indicating the wear rate, replacement time, and replacement work history of a first consumable part, and second consumable part status information indicating the wear rate, replacement time, and replacement work history of a second consumable part different from the first consumable part. The status maintenance information output unit 182 outputs the status maintenance information to the user terminal 200.

[0086] Therefore, the user terminal 200 is capable of displaying the consumable part status information included in the status maintenance information acquired from the maintenance schedule management device 100. For example, as shown in FIG. 14, the user terminal 200 is capable of displaying a list of the consumable part status information on a consumable part status list screen 800 which displays a list of the statuses of the consumable parts. On the consumable part status list screen 800, for example, information such as the wear rate, replacement time, and replacement work history of each consumable part are displayed in a list arranged in the left-right direction. Note that the consumable part status list screen 800 allows the user to perform various display changes such as deciding whether to display or hide the information displayed in the list and rearranging the information by operating the user terminal 200.

[0087] Returning to Fig. 13, in this embodiment, when the state maintenance information includes the first state maintenance information and the second state maintenance information, if the degree of deterioration of the state of the maintenance target device 10 identifiable by the first state maintenance information is higher than the degree of deterioration of the state of the maintenance target device 10 identifiable by the second state maintenance information, the maintenance information setting unit 140 sets the scheduled maintenance date and time information based on the first state maintenance information in preference to the scheduled maintenance date and time information based on the second state maintenance information. For example, the maintenance information setting unit 140 refers to the first state maintenance information and the second state maintenance information, and when the state of the second maintenance target device 12 is deteriorating as usual while the state of the first maintenance target device 11 is rapidly deteriorating, the scheduled maintenance date and time of the first maintenance target device 11 is calculated to be earlier than the scheduled maintenance date and time of the second maintenance target device 12.

[0088] In this embodiment, the user terminal 200, although not shown, is capable of inputting not only information corresponding to the items "task name", "standard", and "manual" but also maintenance work skill level information, which is information indicating the skill level required for maintenance work, on the maintenance information editing screen 500 by the user. Therefore, when the save button 540 is operated, the user terminal 200 also outputs the maintenance work skill level information as information displayed on the editing screen 500. The maintenance work skill level information is, for example, information indicating that the skill level required for the maintenance work specified by the maintenance information is "level 3".

[0089] In addition, in this embodiment, the user terminal 200 is capable of outputting user information, which is information indicating the user's maintenance work skill level, and work schedule information, which is information indicating a work schedule that can identify the date and time when the user will come to work, together with maintenance work skill level information. Note that the user information is information that can be identified for each user name, such as information such as "Level 4" as the maintenance work skill level of a user with the user name "User A". In addition, the work schedule information is information that can be identified for each user name, such as information such as "2022 / 08 / 22 9:00-17:00", "2022 / 08 / 23 9:00-17:00", ..., "2022 / 08 / 26 9:00-17:00".

[0090] For this reason, the maintenance information setting unit 140 refers to the user information, work schedule information, and maintenance work skill level information included in the information acquired by the user side information acquisition unit 130 from the user terminal 200, and sets the maintenance scheduled date and time information indicating the date and time when a user who has reached the maintenance work skill level indicated by the maintenance work skill level information can perform maintenance work in the maintenance schedule. For example, when the maintenance work skill level indicated by the maintenance work skill level information is "Level 3", the maintenance information setting unit 140 can set the maintenance scheduled date and time information indicating "2022 / 08 / 22 9:00 to 17:00", which is the date and time when "User A", a user whose skill level is "Level 3" or higher, can perform maintenance work, in the maintenance schedule.

[0091] As described above, according to the maintenance schedule management system 1 of this embodiment, in the maintenance schedule management device 100, the periodic maintenance information generation unit 181 generates periodic maintenance information based on the history of scheduled maintenance date and time information set based on the status maintenance information. In this way, the maintenance schedule management device 100 can automatically generate not only the status maintenance information but also the periodic maintenance information based on the status maintenance information. As a result, in the maintenance schedule management system 1 according to the present embodiment, if the required accuracy is confirmed in the maintenance work based on the status maintenance information, the maintenance work based on the status maintenance information can be switched to the maintenance work based on the periodic maintenance information.

[0092] Moreover, according to the maintenance schedule management system 1 of this embodiment, in the maintenance schedule management device 100, the maintenance information setting unit 140 can set scheduled maintenance date and time information based on the first state maintenance information and scheduled maintenance date and time information based on the second state maintenance information. Then, when the degree of deterioration of the state of the maintenance target device 10 identifiable by the first state maintenance information is higher than the degree of deterioration of the state of the maintenance target device 10 identifiable by the second state maintenance information, the maintenance information setting unit 140 sets the scheduled maintenance date and time information based on the first state maintenance information in preference to the scheduled maintenance date and time information based on the second state maintenance information. In this manner, in the maintenance schedule management system 1 according to this embodiment, when the condition of one maintenance target device 10 rapidly deteriorates, the scheduled maintenance date and time for that one maintenance target device 10 can be set to the closest date and time when maintenance work can be performed, regardless of the scheduled maintenance dates and times for the other maintenance target devices 10.

[0093] Furthermore, according to the maintenance schedule management system 1 of this embodiment, in the maintenance schedule management device 100, the maintenance information includes maintenance work skill level information indicating the skill level required for maintenance work. Then, the maintenance information setting unit 140 acquires user information, work schedule information, and maintenance work skill level information from the user terminal 200, and sets scheduled maintenance date and time information indicating the date and time when maintenance work can be performed by a user who has reached the maintenance work skill level indicated by the maintenance work skill level information. In this way, in the maintenance schedule management system 1 of this embodiment, maintenance information can be set in the maintenance schedule to match the work schedule of a user who has reached the maintenance work skill level, thereby ensuring that maintenance work is performed by that user. In addition, the maintenance schedule management system 1 according to the present embodiment exerts the same effects as the maintenance schedule management system 1 according to the first embodiment.

[0094] (Example of change) In the above-mentioned first and second embodiments, the maintenance information setting unit 140 is capable of setting the maintenance information in the maintenance schedule based on the periodic maintenance information or the status maintenance information, but is not limited to this. For example, the maintenance information setting unit 140 may be capable of setting the maintenance information in the maintenance schedule based only on the status maintenance information.

[0095] In the above first and second embodiments, the maintenance schedule management device 100 generates the status maintenance information based on the output information from the maintenance target device 10 acquired from the edge terminal 20, but the present invention is not limited to this. For example, the status maintenance information may be generated based on the output information from the maintenance target device 10 collected by the edge terminal 20, and the maintenance schedule management device 100 may acquire the status maintenance information generated by the edge terminal 20. In this way, the maintenance schedule management device 100 can omit the status maintenance information generation unit 125.

[0096] In the above-mentioned first and second embodiments, the user terminal 200 can edit the maintenance target device related information stored in the maintenance target device related information storage unit 110 on an editing screen and output the information, but the user terminal 200 may not be able to edit the maintenance target device related information. For example, the maintenance schedule management device 100 may generate the maintenance target device related information based on the input information by the administrator, and store the generated maintenance target device related information in the maintenance target device related information storage unit 110. In the above-mentioned first and second embodiments, the user terminal 200 can edit the consumable part related information stored in the consumable part related information storage unit 115 on an editing screen and output the information, but the user terminal 200 may not be able to edit the consumable part related information. For example, the maintenance schedule management device 100 may generate the consumable part related information based on the input information by the administrator, and store the generated consumable part related information in the consumable part related information storage unit 115.

[0097] The maintenance information displayed on the maintenance information screen 610 shown in Fig. 9, the maintenance calendar screen 700 shown in Fig. 10, and the maintenance status list screen 750 shown in Fig. 11 in the above first and second embodiments may be displayed in different colors, highlighted, or blinking depending on conditions such as classification and importance. In this case, for example, on the maintenance information editing screen 500 shown in Fig. 7A to 7D, the user may be able to select a display color for color-coding each piece of maintenance information, select whether to highlight the information, or select whether to blink the information.

[0098] In the above first and second embodiments, the maintenance status information is information that can identify whether the status of the maintenance work is "scheduled to be performed," "in progress," or "completed," but the information is not limited to this as long as it is information related to the status of the maintenance work. For example, if the status of the maintenance work identified by the maintenance status information is "completed," the maintenance status information may include an implementation report on the maintenance work acquired by the user-side information acquisition unit 130 from the user terminal 200, information corresponding to the "remarks" item such as handover to the next maintenance work, and information on images related to the maintenance work.

[0099] In the above-mentioned first and second embodiments, the maintenance information setting unit 140 switches the information on which the scheduled maintenance date and time information is generated and set from the periodic maintenance information to the status maintenance information when the accuracy of judging the deterioration of the status of the maintenance target device 10 identified from the status maintenance information is high, but the switching from the periodic maintenance information to the status maintenance information is not limited to this. For example, the maintenance information setting unit 140 may automatically switch from the periodic maintenance information to the status maintenance information when the status of the maintenance target device 10 identified from the status maintenance information is rapidly deteriorating.

[0100] The central part of the maintenance schedule management device 100, which includes the control unit 51, main memory unit 52, external memory unit 53, transmission / reception unit 56, and internal bus 50, may be configured by distributing a control program 59 for executing the above-mentioned operations by storing it in a recording medium readable by the maintenance schedule management device 100, such as a flash memory, and installing the control program 59 to configure the maintenance schedule management device 100. Alternatively, the control program 59 may be stored in a storage device of a server device on a communication network, and the maintenance schedule management device 100 may download the control program 59 to configure the maintenance schedule management device 100.

[0101] Furthermore, when the functions of the maintenance schedule management device 100 are realized by sharing between an OS (Operating System) and an application program, or by cooperation between the OS and the application program, only the application program portion may be stored in a recording medium or storage device.

[0102] It is also possible to superimpose the control program 59 on a carrier wave and provide it via a communication network. For example, the control program 59 may be posted on a bulletin board (BBS, Bulletin Board System) on the communication network and provided via the communication network. Then, the control program 59 may be started and executed under the control of the OS in the same way as other application programs, thereby executing the above-mentioned processing.

[0103] Various embodiments and modifications of the present disclosure are possible without departing from the broad spirit and scope of the present disclosure. The above-described embodiments are for explaining the present disclosure and do not limit the scope of the present disclosure. In other words, the scope of the present disclosure is indicated by the claims, not the embodiments.
