The alert issuance control unit issues an alert on the user terminal. The alert history display control unit displays the alert history on the user terminal. The alert details display control unit displays details of the selected alert on the user terminal when any of the alerts displayed in the alert history is selected on the user terminal.

[0006] An aspect of the present invention provides an operation monitoring method for monitoring an operation state of an industrial machine. The operation monitoring method includes displaying specific information related to the operation state of the industrial machine. The operation monitoring method includes issuing an alert corresponding to a trouble caused by a trouble occurring in the industrial machine. The operation monitoring method includes displaying an alert history including the issued alert. The operation monitoring method includes displaying details of the selected alert when any of the alerts displayed in the alert history is selected. The operation monitoring method issues an alert corresponding to the trouble caused by a trouble occurring in the industrial machine in a user terminal used in a factory in which the industrial machine is installed. The operation monitoring method displays details of the selected alert in the user terminal when any of the alerts displayed in the alert history is selected in the user terminal. Effect of the Invention

[0007] According to the operation monitoring system and operation monitoring method relating to aspects of the present invention, a user terminal used in a factory where industrial machinery is installed displays the operating status of the industrial machinery, issues alerts corresponding to troubles with the industrial machinery, displays the history of issued alerts, and displays details of alerts selected from the alert history. Therefore, if a trouble occurs with the industrial machinery, various information can be confirmed without the intervention of a maintenance person (maintenance terminal), allowing for rapid recovery.

[0008] In the operation monitoring system of the above aspect, the alert details display control unit may display, as the details of the alert, a method for dealing with the trouble that caused the selected alert. According to this aspect, the user of the user terminal can confirm the method for dealing with the trouble that caused the alert without the intervention of a maintenance person (maintenance terminal), so that the trouble in the industrial machine can be quickly restored. In the operation monitoring system of the above aspect, the alert details display control unit may display, as the details of the alert, the status of the industrial machine when the selected alert was issued. According to this aspect, the user of the user terminal can confirm the status of the industrial machine when the alert was issued without the intervention of a maintenance person (maintenance terminal), so that the trouble in the industrial machine can be quickly grasped and quickly restored. In the operation monitoring system of the above aspect, the user terminal can make an inquiry to a maintenance person who maintains the industrial machine about the issued alert, and the alert details display control unit may display, as the details of the alert, a history of inquiries about the issuance of an alert of the same type as the selected alert. According to this aspect, since the user of the user terminal can check the past alerts of the same type as the alert that has occurred this time without the intervention of the maintenance person (maintenance terminal), there is a possibility that the trouble of the industrial machine can be solved in the same way as the past alerts, and a quick recovery can be realized. In addition, in the operation monitoring system of the above aspect, when an inquiry is made, the operation status display control unit may cause the maintenance terminal used by the maintenance person to display the same specific information as that of the user terminal that made the inquiry, the alert history display control unit may cause the maintenance terminal to display the same alert history as that of the user terminal that made the inquiry, and when an inquiry is made, the alert details display control unit may cause the maintenance terminal to display details of the selected alert when any of the alerts displayed in the alert history is selected on the maintenance terminal. According to this aspect, since the same information as that of the user terminal can be confirmed on the maintenance terminal, the same information can be shared between the user of the user terminal and the maintenance person, and the trouble of the industrial machine can be quickly dealt with.The operation monitoring system of the above aspect may further include an inquiry display control unit that displays a user interface for making an inquiry on the user terminal when an alert is issued by the alert issuance control unit. According to this aspect, the user of the user terminal can inquire of a maintenance person about a trouble with the industrial machinery that is difficult for the user to solve, so that the trouble with the industrial machinery can be quickly dealt with. The operation monitoring system of the above aspect may further include a server device that can communicate with the user terminal, and the server device may include an operation status display control unit, an alert issuance control unit, an alert history display control unit, and an alert details display control unit. According to this aspect, while centrally managing information from the industrial machinery, an alert can be quickly issued when a trouble occurs in the industrial machinery, so that the trouble in the industrial machinery can be quickly restored.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The present invention will be described below through the embodiments of the invention. The following embodiments do not limit the scope of the invention. In the drawings, the scale may be appropriately changed, such as enlarging, reducing, or emphasizing a part in order to explain the embodiments.

[0011] Fig. 1 is a diagram showing an example of a system configuration of an operation monitoring system 1 according to an embodiment. As shown in Fig. 1, the operation monitoring system 1 has an industrial machine 20, a user terminal 30, a maintenance terminal 40, and a server device 100, and is a system that monitors the operation state of the industrial machine 20. The industrial machine 20 is, for example, a machine tool or a conveying device installed in a factory or the like. The industrial machine 20 appropriately transmits various information about its own status to the server device 100. The information appropriately transmitted from the industrial machine 20 to the server device 100 includes information about the operation of the industrial machine 20, information about troubles that occur during operation, and the like.

[0012] The server device 100 stores various statuses of the industrial machine 20 received from the industrial machine 20 in a storage device (e.g., the storage device 105 described later, etc.). Then, the server device 100 controls the display of various screens based on various statuses of the industrial machine 20 in response to requests from the user terminal 30 and the maintenance terminal 40. Furthermore, the server device 100 issues an alert to the user terminal 30 when a trouble occurs in the industrial machine 20. In this way, the server device 100 is capable of bidirectional communication with the user terminal 30 and the maintenance terminal 40. Note that the server device 100 in the operation monitoring system 1 may be a single device, or may be configured with multiple devices depending on functions and roles. Furthermore, the industrial machine 20, the user terminal 30, and the maintenance terminal 40 may each be multiple rather than one.

[0013] The user terminal 30 is, for example, a terminal used in a factory or the like where the industrial machine 20 is installed. In this embodiment, the user terminal 30 is described assuming that it is a tablet terminal, but is not limited to this, and may be an information processing device such as a PC (Personal Computer). In response to a user operation, the user terminal 30 requests the server device 100 to display a screen relating to various conditions of the industrial machine 20, and displays the screen on its own display unit based on a response from the server device 100 to the request.

[0014] The maintenance terminal 40 is, for example, a terminal used by a maintenance person who maintains the industrial machine 20. The maintenance terminal 40 is, for example, a terminal used at a maintenance base that is located at a location geographically different from a factory where the industrial machine 20 is installed. In this embodiment, the maintenance terminal 40 is described assuming an information processing device such as a PC, but is not limited to this and may be an information device such as a tablet terminal. In response to a user operation, the maintenance terminal 40 requests the server device 100 to display a screen related to various conditions of the industrial machine 20, and displays a screen on its own display unit based on a response from the server device 100 to the request.

[0015] 2 is a diagram illustrating an example of a functional configuration of the server device 100 according to an embodiment. As illustrated in FIG. 2, the server device 100 includes an operation status display control unit 110, an alert issuance control unit 120, an inquiry display control unit 130, an alert history display control unit 140, and an alert details display control unit 150.

[0016] The operation state display control unit 110 displays specific information related to the operation state of the industrial machine 20. Specifically, the operation state display control unit 110 displays the specific information on the user terminal 30 in response to a request from the user terminal 30 used in the factory where the industrial machine 20 is installed. Similarly, the operation state display control unit 110 displays the specific information on the maintenance terminal 40 in response to a request from the maintenance terminal 40 used at the maintenance base. Note that, although details will be described later, when an inquiry is made from the user terminal 30 to the maintenance terminal 40 (maintenance person), the operation state display control unit 110 can display, on the maintenance terminal 40, the same specific information of the industrial machine 20 as that of the user terminal 30 that made the inquiry.

[0017] When a trouble occurs in the industrial machinery 20, the alert issuance control unit 120 issues an alert corresponding to the trouble. Specifically, when the alert issuance control unit 120 receives information from the industrial machinery 20 that a trouble has occurred, the alert issuance control unit 120 causes the user terminal 30 to issue an alert corresponding to the trouble. Regarding the issuance of the alert, the alert issuance control unit 120 causes a predetermined screen of the user terminal 30 to display information that a trouble has occurred in the industrial machinery 20. Details of the issuance of an alert will be described later, but in response to the issuance of the alert, the user of the user terminal 30 may make an inquiry to the maintenance terminal 40 (maintenance person) in order to solve the trouble in the industrial machinery 20.

[0018] When an alert is issued by the alert issuance control unit 120, the inquiry display control unit 130 displays a user interface for making an inquiry on the user terminal 30. Specifically, the inquiry display control unit 130 displays a user interface (e.g., an inquiry button, etc.) for making an inquiry about the alert at an arbitrary position on a screen for confirming the alert issued by the alert issuance control unit 120 on the user terminal 30. The user of the user terminal 30 can use the user interface for making an inquiry to the maintenance terminal 40 (maintenance person) about how to handle the alert.

[0019] The alert history display control unit 140 displays an alert history including an alert issued by the alert issuance control unit 120. That is, the alert history display control unit 140 displays not only an alert issued by the alert issuance control unit 120 but also an alert history including the alert and past alerts issued for the industrial machine 20 that is the target of the alert. Specifically, the alert history display control unit 140 displays an alert history including an alert issued by the alert issuance control unit 120 on the user terminal 30 in response to a request from the user terminal 30. Furthermore, the alert history display control unit 140 displays on the maintenance terminal 40 the same alert history as the alert history displayed on the user terminal 30 in response to a request from the maintenance terminal 40. Note that, although details will be described later, when an inquiry is made from the user terminal 30 to the maintenance terminal 40 (maintenance person), the alert history display control unit 140 can display on the maintenance terminal 40 the alert history of the industrial machine 20 similar to that of the user terminal 30 that made the inquiry.

[0020] The alert details display control unit 150 displays details of the selected alert when any of the alerts displayed in the alert history is selected on the user terminal 30. Specifically, the alert details display control unit 150 displays details of the selected alert on the user terminal 30 when any of the alerts displayed in the alert history is selected on the user terminal 30. Furthermore, in response to a request from the maintenance terminal 40, the alert details display control unit 150 displays on the maintenance terminal 40 details of the alert history that are the same as the details of the alert history displayed on the user terminal 30. Note that, although details will be described later, when an inquiry is made from the user terminal 30 to the maintenance terminal 40 (maintenance person), the alert details display control unit 150 can display on the maintenance terminal 40 details of the alert history of the same industrial machine 20 as that of the user terminal 30 that made the inquiry.

[0021] 3 is a diagram showing an example of a hardware configuration of a server device 100 according to an embodiment. The server device 100 is realized, for example, by a hardware configuration similar to that of a general-purpose computer, etc. The server device 100 executes a predetermined program to realize each function of an operation status display control unit 110, an alert issuance control unit 120, an inquiry display control unit 130, an alert history display control unit 140, and an alert details display control unit 150.

[0022] As shown in FIG. 3, the server device 100 includes a CPU (Central Processing Unit) 101, a ROM (Read Only Memory) 102, a RAM (Random Access Memory) 103, a communication device 104, and a storage device 105. The above-mentioned components are connected by a bus 106. The CPU 101 is a processor that executes various processes, and loads a predetermined program stored in the storage device 105 or the like into the RAM 103 and executes it, controls each component to perform input / output, and controls the display of various screens. The CPU 101 may be configured with one or more processors. The ROM 102 stores a start program that reads a boot program from the storage device 105 to the RAM 103. The RAM 103 stores various data as a working area for the CPU 101.

[0023] The communication device 104 transmits and receives information to and from external devices (e.g., industrial machinery 20, user terminal 30, maintenance terminal 40, etc.) via a network. The storage device 105 is, for example, a hard disk drive or a flash memory. The storage device 105 stores a predetermined program executed by the server device 100 and an operating system. In addition, the server device 100 may be equipped with an input device and an output device. The input device is, for example, an input device such as a mouse or a keyboard, which accepts information entered by operation as a signal and outputs it to the CPU 101. The output device is, for example, a display device such as a liquid crystal display, which displays and outputs various information based on signals from the CPU 101.

[0024] The predetermined program executed by the server device 100 is provided by being stored in a computer-readable recording medium such as a CD-ROM, a flexible disk, a CD-R, or a DVD as a file in an installable or executable format. The predetermined program executed by the server device 100 may be provided by being stored on a computer connected to a network such as the Internet and downloaded via the network. The predetermined program executed by the server device 100 may be provided or distributed via a network such as the Internet. The predetermined program executed by the server device 100 may be provided by being pre-installed in ROM 102 or the like.

[0025] The predetermined program includes at least a module functioning as the operation status display control unit 110, a module functioning as the alert issuance control unit 120, a module functioning as the inquiry display control unit 130, a module functioning as the alert history display control unit 140, and a module functioning as the alert details display control unit 150. In the server device 100, the CPU 101 as a processor reads out and executes a predetermined program from the storage device 105 or the like, whereby each module is loaded onto the RAM 103, and the CPU 101 functions as the operation status display control unit 110, the alert issuance control unit 120, the inquiry display control unit 130, the alert history display control unit 140, and the alert details display control unit 150. Note that each function may be realized partly or entirely by hardware other than the processor. Also, each function may be realized by cloud computing executed via a network.

[0026] Fig. 4 is a process sequence diagram showing an example of the flow of processes in the operation monitoring system 1 according to the embodiment. In Fig. 4, a process sequence between the industrial machine 20, the user terminal 30, and the server device 100 will be described.

[0027] As shown in FIG. 4, the industrial machine 20 provides various information such as information on its own operation to the server device 100 (step S101). The industrial machine 20 provides information to the server device 100 as needed. As a result, the server device 100 stores the information provided by the industrial machine 20 in the storage device 105. The user terminal 30 requests the server device 100 to display a screen related to various conditions of the industrial machine 20 in response to a user operation (step S102). The server device 100 controls the display of various screens based on the various conditions of the industrial machine 20 stored in the storage device 105 in response to a request from the user terminal 30 (step S103). As a result, the user terminal 30 displays various screens on the display unit. The user terminal 30 and the server device 100 exchange information with each other in response to a user operation performed at any timing.

[0028] Furthermore, if a trouble occurs during the operation of the industrial machinery 20, the industrial machinery 20 provides information related to the trouble to the server device 100 (step S104). If the server device 100 receives information related to the trouble from the industrial machinery 20, it issues an alert to the user terminal 30 (step S105). Note that, as described in steps S102 and S103, the user terminal 30 that has received the issuance of the alert is in a state in which it can request the server device 100 to display information required regarding the alert. If the user terminal 30 requests the server device 100 to display information required regarding the alert, various screens are displayed on the display unit in response to the response from the server device 100.

[0029] Hereinafter, various screens from the occurrence of an alert to an inquiry will be described with reference to FIGS.

[0030] FIG. 5 is a diagram showing an example of a list screen of industrial machines 20 displayed on a user terminal 30 according to an embodiment. As shown in FIG. 5, after a login operation is performed on the user terminal 30 based on a predetermined ID and password, etc., a list screen of industrial machines 20 installed in a factory is displayed. The list screen of industrial machines 20 includes the status of each industrial machine 20 (e.g., stopped, in preparation, on standby, in processing, etc.). The status of each industrial machine 20 displayed on the list screen of industrial machines 20 is displayed based on information responded from the server device 100 based on a display request from the user terminal 30. In addition, when an operation of selecting any one of industrial machines 20 from the list screen of industrial machines 20 is performed, the user terminal 30 transmits a display request for the (individual) operating status of the selected industrial machine 20 to the server device 100.

[0031] 6 and 7 are diagrams showing an example of an operation status screen of the industrial machinery 20 displayed on the user terminal 30 according to the embodiment. As shown in FIG. 6 and FIG. 7, in the user terminal 30, an operation status screen is displayed as specific information of the industrial machinery 20 in response to a display request for the operation status from the server device 100. For example, as shown in FIG. 6, the operation status screen includes, as the operation status of the industrial machinery 20, "stopped - 1 hour ago" and an occurring alert. In addition, the operation status screen may include the operation rate of the industrial machinery 20, information about the main body, operation results, consumption of electricity, gas, etc., past processing history, etc. As shown in FIG. 7, the user can check information indicating an inspection that has reached its scheduled date and notifications of new messages (e.g., inquiry messages) in addition to the occurring alerts by selecting a predetermined icon (here, the bell icon at the top) on the operation status screen. As described above, an alert is issued by the alert issuing control unit 120 in response to the occurrence of a trouble in the industrial machinery 20. Furthermore, when an operation for selecting any one of the alerts from the operation status screen is performed, the user terminal 30 transmits to the server device 100 a request for displaying details of the selected alert.

[0032] FIG. 8 is a diagram showing an example of an alert history screen displayed on the user terminal 30 according to the embodiment. As shown in FIG. 8, the alert history screen includes a history of alerts corresponding to the industrial machine 20. Specifically, the alert history screen includes not only a currently issued alert corresponding to the industrial machine 20, but also a history of one or more alerts issued in the past for the industrial machine 20. That is, the alert history screen displays a list of multiple alerts that have been issued currently and in the past for the industrial machine 20 for which an alert is currently issued. For example, the user can check the alert history corresponding to the selected industrial machine 20 by selecting one of the industrial machines 20 from the list screen and then selecting the alert history from a menu (not shown) displayed on the screen. That is, when an operation of selecting the alert history from the menu displayed on the screen is performed, the user terminal 30 transmits a display request for the alert history of the corresponding industrial machine 20 to the server device 100. As a result, the alert history display control unit 140 causes the user terminal 30 to display the alert history including the alerts issued to the corresponding industrial machine 20. The alert history screen displays the issued alerts in chronological order regardless of whether they are occurring or not.

[0033] 9 to 12 are diagrams showing examples of an alert details screen displayed on the user terminal 30 according to the embodiment. As shown in FIG. 9 to FIG. 12, the user terminal 30 displays an alert details screen of a selected alert in response to a request to display details of the alert from the server device 100. In FIG. 9, the "treatment information" tab on the alert details screen is selected. In response to a request to display details of the alert from the user terminal 30, the alert details display control unit 150 displays, as details of the alert, a method of dealing with a trouble in the industrial machine 20 that caused the selected alert. As a result, as shown in FIG. 9, the alert details screen includes, for the alert (trouble in the industrial machine 20), when it occurred, what the cause is, an overall view of the corresponding industrial machine 20, a treatment flow, and the like. Note that, as shown in FIG. 9, the display of the overall view of the industrial machine 20, treatment (treatment flow), and the like may be realized by folding display.

[0034] In FIG. 10, the "Occurrence Status" tab on the alert details screen is selected. In response to a display request for details of the alert from the user terminal 30, the alert details display control unit 150 displays, as details of the alert, the status of the industrial machinery 20 when the selected alert was issued. For example, the status of the industrial machinery 20 includes an image (video) when a trouble occurs. That is, the industrial machinery 20 is equipped with a sensor that captures video, and when a trouble occurs, the video captured by the sensor is also transmitted to the server device 100. As a result, as shown in FIG. 10, the alert details screen includes an image (video) when a trouble occurs in the industrial machinery 20.

[0035] In Fig. 11, the "Previous and Next Alerts" tab on the alert details screen is selected. In response to a request from the user terminal 30 to display details of an alert, the alert details display control unit 150 displays other alerts that occurred before and after the time when the selected alert occurred. The other alerts do not need to have the same alert number as the selected alert. In other words, since the occurrence of one trouble may induce multiple troubles in the industrial machinery 20, not only alerts of the same type but also other types of alerts are displayed as "previous and next alerts."

[0036] As a result, as shown in Fig. 11, the alert details screen includes alerts that occurred before and after the occurrence time of the selected alert, and further includes alerts of various types, not limited to the same type. The user can select any alert from the "Previous and Next Alerts" tab, and this selection makes it possible to check the alert history (see Fig. 8) of the corresponding industrial machine 20. That is, when an operation to select any alert from the "Previous and Next Alerts" tab is performed, the user terminal 30 transmits a display request for the alert history to the server device 100, and displays the alert history shown in Fig. 8 based on the response from the server device 100.

[0037] In FIG. 12, the "Inquiry History" tab on the alert details screen is selected. In response to a display request for alert details from the user terminal 30, the alert details display control unit 150 displays the history of inquiries in which the same type of alert as the selected alert was issued. By displaying the inquiry history in which the same type of alert as the selected alert was issued, it is possible that the current trouble of the industrial machine 20 can be solved by the same treatment as that of the past inquiry. For this reason, as shown in FIG. 12, the alert details screen includes the inquiry history in which the same type of alert as the selected alert was issued. Note that the user can select any of the alerts in the "Inquiry History" tab, and this selection allows the user to check the treatment information of the corresponding alert. That is, when an operation is performed to select any of the alerts from the "Inquiry History" tab, the user terminal 30 transmits a display request for details of the selected alert to the server device 100, and displays the treatment information of the corresponding industrial machine 20 based on the response from the server device 100. In such a case, it is possible that the current alert can be solved by the same treatment as that of the alert for which an inquiry was made in the past.

[0038] The user of the user terminal 30 can make an inquiry to the maintenance terminal 40 (maintenance person) from the alert details screen. For this purpose, the alert details screen includes an "inquiry button" (e.g., an oval-shaped user interface shown in FIG. 12) for making an inquiry to the maintenance terminal 40 (maintenance person). When an alert is issued by the alert issuance control unit 120, the inquiry display control unit 130 displays a user interface for making an inquiry (e.g., an inquiry button) on the user terminal 30. After pressing the inquiry button, the user of the user terminal 30 inputs the necessary information for the inquiry on an inquiry form screen (not shown) and presses a send button or the like. As a result, the user terminal 30 transmits the information input on the inquiry form screen to the maintenance terminal 40 via the server device 100.

[0045] FIG. 19 is a flowchart showing an example of the flow of the display control process of the details of an alert for the user terminal 30 according to the embodiment. As shown in FIG. 19, when any of the alerts from the alert history is selected on the user terminal 30 (step S601: YES), the alert details display control unit 150 displays the details of the selected alert on the user terminal 30 (step S602). On the other hand, when any of the alerts from the alert history is not selected on the user terminal 30 (step S601: NO), the alert details display control unit 150 enters a state of waiting for the selection of any of the alerts from the alert history. Specifically, the alert details display control unit 150 accepts a request to display the details of an alert when any of the alerts displayed in the alert history is selected on the user terminal 30, and displays the details of the selected alert on the user terminal 30.

[0046] Fig. 20 is a process sequence diagram showing an example of the flow of processes in the operation monitoring system 1 according to the embodiment. In Fig. 20, a process sequence between the user terminal 30, the maintenance terminal 40, and the server device 100 will be described.

[0047] As shown in FIG. 20, the user terminal 30 receives an alert due to a trouble in the industrial machine 20 and makes some kind of inquiry about the trouble (step S701). The inquiry is transmitted to the maintenance terminal 40 via the server device 100. When the maintenance terminal 40 accepts the inquiry from the user terminal 30, it requests the server device 100 to display some kind of screen related to the corresponding industrial machine 20 (step S702). In response to the request from the maintenance terminal 40, the server device 100 controls the display of various screens based on various conditions of the industrial machine 20 stored in the storage device 105 (step S703). As a result, the maintenance terminal 40 displays various screens on the display unit. Note that the exchange between the maintenance terminal 40 and the server device 100 is performed in response to an operation by a maintenance person performed at any timing after the inquiry from the user terminal 30 is accepted.

[0048] Similarly to steps S102 and S103, the user terminal 30 requests the server device 100 to display some kind of screen regarding various statuses of the industrial machinery 20 in response to a user operation (step S704). The server device 100 controls the display of various screens based on the various statuses of the industrial machinery 20 stored in the storage device 105 in response to the request from the user terminal 30 (step S705). As a result, the user terminal 30 displays various screens on the display unit. Note that the interaction between the user terminal 30 and the server device 100 is performed in response to a user operation performed at any timing.

[0049] In this way, in a state in which the same information regarding the same industrial machine 20 can be confirmed on the user terminal 30 side and the maintenance terminal 40 side, the user terminal 30 and the maintenance terminal 40 can communicate with each other via chat communication or the like (step S706).

[0050] The following describes the exchange between the user terminal 30 and the maintenance terminal 40 in response to an inquiry.

[0051] After a login operation is performed on the maintenance terminal 40 based on a specified ID and password, etc., a list screen of customers in which each industrial machine 20 is installed is displayed. The customer list screen includes customer information such as the company name and company address. The customer list screen also displays a notification that an inquiry has been made. The customer list screen may also include a switching function for displaying only customers for which an inquiry is being handled, in addition to displaying all customers. The maintenance person can check the information of the selected customer by selecting any one of the customers from the customer list screen. The maintenance person can also check the alert history screen on the maintenance terminal 40 by selecting the inquiry notification displayed on the customer list screen.

[0052] The maintenance terminal 40 can display a customer information screen relating to a specific customer. The customer information screen includes information such as the contact information and person in charge of the customer who is the subject of maintenance, as well as inquiry history, information on the owned industrial machinery 20, and the like. For example, the inquiry history displays the status of each inquiry (e.g., not accepted, accepted, completed, etc., as shown in FIG. 13). Also, the information on the owned industrial machinery 20 displays the state of each owned industrial machinery 20 (e.g., stopped, waiting, in preparation, in processing, etc., as shown in FIG. 5).

[0053] The maintenance terminal 40 can display an operation status screen of the industrial machinery 20, similar to the operation status screen displayed on the user terminal 30 shown in FIG. 6. In response to the request to display the operation status from the server device 100, the maintenance terminal 40 displays the operation status screen as specific information of the industrial machinery 20. For example, when any of the owned industrial machinery 20 is selected on the screen displaying the status of each industrial machinery 20, the operation status screen displayed on the maintenance terminal 40 is treated as a request to display the operation status of the corresponding industrial machinery 20, and is displayed in response to the request. The operation status screen displayed on the maintenance terminal 40 is the same as the operation status screen displayed on the user terminal 30. When an operation to select any of the alerts from the operation status screen is performed, the maintenance terminal 40 transmits a request to the server device 100 to display details of the selected alert.

[0054] The maintenance terminal 40 can display an alert history screen similar to the alert history screen displayed on the user terminal 30 shown in Fig. 8. The alert history screen includes the alert history of the customer and the alert history for each industrial machine 20.

[0055] The maintenance terminal 40 can display an alert details screen similar to the alert details screen displayed on the user terminal 30 shown in Figs. 9 to 12. In response to a request to display alert details from the server device 100, the maintenance terminal 40 displays an alert details screen of an alert selected from the alert history or the like. For example, the maintenance terminal 40 can display the "Treatment Information" tab shown in Fig. 9, the "Occurrence Status" tab shown in Fig. 10, the "Previous and Next Alerts" tab shown in Fig. 11, and the "Inquiry History" tab shown in Fig. 12. In this way, various information that can be confirmed on the user terminal 30 can also be confirmed on the maintenance terminal 40.

[0056] The maintenance terminal 40 can display an inquiry list screen. For example, the inquiry list screen includes an overview of inquiries from customers who are the targets of maintenance. The inquiry list screen can display all inquiries, including unaccepted inquiries, inquiries currently being handled (handled), and both, by using a switching function using tabs, etc. When an inquiry is selected on the inquiry list screen, the maintenance terminal 40 transmits a display request to the server device 100 for an inquiry response screen for the selected inquiry, and displays the inquiry response screen based on the response from the server device 100.

[0057] The maintenance terminal 40 can display an inquiry response screen for inquiries from the user terminal 30. The inquiry response screen includes alert details of the industrial machine 20 in response to the inquiry and a chat screen for responding to the inquiry. The alert details and chat screen included in the inquiry response screen are the same as the alert details and chat screen included in the inquiry screen displayed on the user terminal 30 shown in FIG. 14. The inquiry response screen also includes a status of the inquiry (e.g., not accepted, accepted, being handled, etc.) and a button that triggers the start of handling (e.g., a "Start handling" button). When an inquiry from the user terminal 30 is accepted, the receptionist on the maintenance side requests the maintenance person to handle the inquiry and inputs a message that the inquiry has been accepted. For example, the receptionist on the maintenance side requests the maintenance person to handle the inquiry through chat, and responds to the customer through chat that the inquiry has been accepted. The chat exchange on the maintenance side (chat exchange between the receptionist and the maintenance person) is not displayed on the user terminal 30. Also, at this point in time, only the chat from the receptionist on the maintenance side is displayed on the user terminal 30.

[0058] The maintenance staff presses the "Start response" button to start response, and then checks the alert details screen and the log information (e.g., by pressing a "Check log information" button, etc.). The maintenance staff may also request a log analysis from the support center (e.g., by pressing a "Request log analysis" button, etc.). Note that chats between the support center staff and the maintenance staff are not displayed on the user terminal 30. Based on the alert details screen, log information, log analysis results, etc., the maintenance staff will notify the user via chat, etc., about how to solve the problem with the industrial machine 20.

[0059] The user of the user terminal 30 attempts to resolve the trouble of the industrial machine 20 based on the notification from the maintenance person of how to resolve the trouble of the industrial machine 20. Then, the user of the user terminal 30 presses a "Complete" button to close the inquiry upon resolving the trouble, and ends the inquiry. Similarly, the maintenance person presses a "Complete" button to close the inquiry response upon resolving the trouble, and ends the inquiry response. The inquiry / inquiry response may be ended when either the user of the user terminal 30 or the maintenance person presses the "Complete" button. Communication between the user terminal 30 and the maintenance terminal 40 by chat or the like is carried out via the server device 100.

[0060] FIG. 21 is a flowchart showing an example of the flow of the display process of the specific information for the maintenance terminal 40 according to the embodiment. As shown in FIG. 21, when the operation state display control unit 110 receives a display request of the specific information from the maintenance terminal 40 (step S801: YES), the operation state display control unit 110 displays the specific information on the maintenance terminal 40 (step S802). On the other hand, when the operation state display control unit 110 does not receive a display request of the specific information from the maintenance terminal 40 (step S801: NO), the operation state display control unit 110 waits for reception of the display request of the specific information. Specifically, when the industrial machine 20 of the customer to be maintained is selected on the maintenance terminal 40, the operation state display control unit 110 receives a display request of the operation status screen as the specific information, and displays the operation status screen of the corresponding industrial machine 20 on the maintenance terminal 40. Here, the maintenance terminal 40 requests the server device 100 to display the same operation status screen as that of the user terminal 30 that made the inquiry. This allows the maintenance person to respond to the inquiry while checking the operation status screen similar to that of the user terminal 30 on the maintenance terminal 40.

[0061] FIG. 22 is a flowchart showing an example of the flow of the display control process of the alert history for the maintenance terminal 40 according to the embodiment. As shown in FIG. 22, when the alert history display control unit 140 receives a display request of the alert history from the maintenance terminal 40 (step S901: YES), the alert history display control unit 140 displays the alert history on the maintenance terminal 40 (step S902). On the other hand, when the alert history display request is not received from the maintenance terminal 40 (step S901: NO), the alert history display control unit 140 enters a state of waiting for reception of the display request of the alert history. Specifically, the alert history display control unit 140 receives a display request of the alert history screen from the maintenance terminal 40 by selecting the industrial machine 20 of the customer to be maintained on the maintenance terminal 40 and then selecting the alert history on the maintenance terminal 40, and displays the alert history screen of the corresponding industrial machine 20 on the maintenance terminal 40. Here, the maintenance terminal 40 makes a display request of the alert history similar to that of the user terminal 30 that made the inquiry to the server device 100. This allows the maintenance person to handle the inquiry while checking the alert history screen similar to that of the user terminal 30 on the maintenance terminal 40.

[0062] FIG. 23 is a flowchart showing an example of the flow of the display control process of the alert details for the maintenance terminal 40 according to the embodiment. As shown in FIG. 23, when any of the alerts from the alert history is selected on the maintenance terminal 40 (step S1001: YES), the alert details display control unit 150 displays the details of the selected alert on the maintenance terminal 40 (step S1002). On the other hand, when any of the alerts from the alert history is not selected on the maintenance terminal 40 (step S1001: NO), the alert details display control unit 150 enters a state of waiting for the selection of any of the alerts from the alert history. Specifically, the alert details display control unit 150 accepts a request to display the details of the alert when any of the alerts displayed in the alert history is selected on the maintenance terminal 40, and displays the details of the selected alert on the maintenance terminal 40.

[0063] As described above, the operation monitoring system 1 displays the operation state of the industrial machine 20, issues an alert corresponding to a trouble in the industrial machine 20, displays the history of issued alerts, and displays details of an alert selected from the alert history on the user terminal 30 used in the factory where the industrial machine 20 is installed.
