[Figure 6] FIG. 10 is a block diagram showing an example of the configuration of a management system according to a second embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0010] [Embodiment 1] <Configuration of management system 100> Fig. 1 is a block diagram showing an example of the configuration of a management system 100 according to a first embodiment of the present invention. As shown in Fig. 1, the management system 100 includes a management device 1, a programmable display device 3, and a plurality of terminal devices 4A, 4B, 4C, and 4D. In Fig. 1, the management system 100 includes four terminal devices 4A to 4D, but is not limited to this, and the management system 100 may include at least two terminal devices.

[0011] <Configuration of management device 1> The management device 1 manages a posting screen on which messages can be posted from a plurality of terminal devices 4A to 4D. The management device 1 includes a server 2 and a BOT 6. The server 2 is a chat server that manages the posting screen. The server 2 includes a communication unit 21, a storage unit 22, and a control unit 23. The BOT 6 is a program that can communicate with the server 2 and the programmable display device 3, and transmits information received from the programmable display device 3 to the server 2.

[0012] The processing of the BOT 6 described in this embodiment may be executed by the server 2. Also, part of the processing of the server 2 described in this embodiment may be executed by the BOT 6. In this case, the detecting unit 233, collecting unit 234, information generating unit 235, and adding unit 236 described below may be provided in the BOT 6. Furthermore, the processing of the BOT 6 described in this embodiment may be executed by the programmable display device 3.

[0013] The communication unit 21 is capable of communicating with the terminal devices 4A to 4D and the BOT 6 via the network. The communication unit 21 is a communication interface that enables the server 2 to communicate with the terminal devices 4A to 4D and the BOT 6. The storage unit 22 stores data and is, for example, a memory.

[0014] The control unit 23 controls each unit of the server 2 and is, for example, a CPU (Central Processing Unit). The control unit 23 has a communication processing unit 231, a storage processing unit 232, a detection unit 233, a collection unit 234, an information generation unit 235, and an addition unit 236. The communication processing unit 231 controls communication by the communication unit 21. The storage processing unit 232 controls storage by the storage unit 22.

[0015] <Programmable Display 3 Configuration> The programmable display 3 is connected to a PLC (Programmable Logic Controller) 7. The programmable display 3 communicates with the PLC 7 by being connected to the PLC 7 via a communication cable. The programmable display 3 is a dedicated computer that realizes the operation and display functions specific to the programmable display by displaying a screen for operation and display, and is used as an HMI (Human Machine Interface) device.

[0016] The programmable display 3 includes a communication unit 31, a display unit 32, an operation unit 33, and a control unit 34. The communication unit 31 is a communication interface for the programmable display 3 to communicate with the BOT 6 and the PLC 7. The display unit 32 displays the state of the device 8 and also displays a screen for operating the device 8. Also, the display unit 32 may display a posting screen. The operation unit 33 is for the user to operate the screen of the display unit 32, and is, for example, a touch panel that accepts touch operations.

[0017] The control unit 34 controls each part of the programmable display 3 and is, for example, a CPU. Also, the control unit 34 executes an operation of displaying the state of the device 8 connected to the PLC 7 and an operation of controlling the state of the device 8 according to an operation on the operation unit 33.

[0018] <Configuration of PLC 7 and Device 8> The PLC 7 is a control device that reads the state of the device 8 and gives a control instruction to the device 8 at a predetermined scan time according to a sequence program created by the user. The device 8 may include, for example, input devices such as sensors or switches, and output devices such as actuators, relays, solenoid valves, or displays.

[0019] <Configuration of Terminal Devices 4A to 4D> The terminal devices 4A to 4D are, for example, portable terminals such as smartphones or tablet PCs, or fixed terminals such as notebook PCs or desktop PCs. Dedicated application software that functions as part of the management system 100 and is used to post and display messages (described later) is installed in the terminal devices 4A to 4D. The terminal device 4A includes a communication unit 41, a display unit 42, an operation unit 43, and a control unit 44. The communication unit 41 is connected to the server 2 via a network. The communication unit 41 is a communication interface that enables the terminal device 4A to communicate with the server 2.

[0020] The display unit 42 displays a posting screen, etc. The operation unit 43 allows the user to operate the screen of the display unit 42, and is, for example, a touch panel that accepts touch operations. The control unit 44 controls each unit of the terminal device 4A, and is, for example, a CPU. Like the terminal device 4A, the terminal devices 4B to 4C each include a communication unit 41, a display unit 42, an operation unit 43, and a control unit 44.

[0021] <Post a message> Fig. 2 is a diagram showing an example of a posting screen PP1 on which messages can be posted from terminal devices 4A to 4D included in the management system 100 shown in Fig. 1. With reference to Fig. 2, it is assumed that users A, B, C, and D are users who operate terminal devices 4A to 4D, respectively, in this order. Furthermore, messages can also be posted from a BOT 6 on the posting screen PP1.

[0022] The communication unit 21 of the server 2 is capable of communicating with the programmable display device 3 via the BOT 6, and is also capable of communicating with the terminal devices 4A to 4D. This allows the display unit 32 of the programmable display device 3 and the display units 42 of the terminal devices 4A to 4D to display the posting screen PP1.

[0023] The management system 100 performs different operations depending on the type of tag added to a message posted on the posting screen PP1. The types of tags added to messages include the following (1) to (5). The detection unit 233 detects the above tags (1) to (4) based on the message posted on the posting screen PP1.

[0024] (1) Alarm response enabled tag or alarm unresponsive tag (2) Alarm occurrence tag (3) Alarm recovery tag (4) Response status request tag (5) Summary information tag <(1) tag> The alarm available tag is a tag indicating that the user is available to respond to the alarm. The alarm unavailable tag is a tag indicating that the user is unavailable to respond to the alarm. The tag (1) above is added to messages sent from the terminal devices 4A to 4D to the server 2. The collection unit 234 collects the tag (1) above detected by the detection unit 233. The information indicated by the tag (1) above is an example of related information related to the generated alarm.

[0025] For example, when user A operates the operation unit 43 to post the message M3 shown in FIG. 2, the control unit 44 of the terminal device 4A uses the communication unit 41 to transmit the message M3 to the server 2. The message M3 includes the message content of user A and a tag TG3. The tag TG3 is an alarm unresponsive tag indicating that user A is unresponsive to an alarm. When posting the message M3, user A can add the tag TG3 to the message M3 by operating the operation unit 43. The message M3 may also include the posting time of the message M3.

[0026] In the server 2, the communication processing unit 231 receives a message M3 from the terminal device 4A using the communication unit 21. The detection unit 233 detects a tag TG3 from the message M3 received by the communication unit 21. The collection unit 234 acquires the tag TG3 detected by the detection unit 233.

[0027] The information generating unit 235 generates the summary information tag (5) for displaying the information indicated by the tag TG3 in the maintenance area A1 of the posting screen PP1. The summary information tag for displaying the information indicated by the tag (1) such as the tag TG3 is an example of first information. Details of the summary information tag will be described later.

[0028] The maintenance area A1 is an area of ​​the posting screen PP1 that remains displayed on the display units 42 of the terminal devices 4A to 4D. For example, when the posting screen PP1 displayed on the display units 42 is scrolled, the maintenance area A1 remains displayed on the display units 42.

[0029] 2, the maintenance area A1 is located at the top of the posting screen PP1, but is not limited to this, and the maintenance area A1 may be located in a part other than the top of the posting screen PP1. The maintenance area A1 may be divided into multiple areas on the posting screen PP1. For example, a part of the maintenance area A1 may be located at the top of the posting screen PP1, and the remaining part of the maintenance area A1 may be located at the bottom of the posting screen PP1.

[0030] The addition unit 236 adds the summary information tag generated by the information generation unit 235 to the information indicated by the tag TG3 acquired by the collection unit 234. The storage processing unit 232 updates the posting screen PP1 stored in the storage unit 22 to add the message M3. At this time, the storage processing unit 232 also stores in the storage unit 22 the information indicated by the tag TG3 to which the summary information tag has been added by the addition unit 236.

[0031] The communication processing unit 231 notifies the terminal devices 4A to 4D using the communication unit 21. At this time, the communication unit 21 transmits the information of the posting screen PP1 stored in the storage unit 22 to the terminal devices 4A to 4D. A message M3 has been added to the posting screen PP1, and the message M3 includes the tag TG3. Therefore, by transmitting the information of the posting screen PP1 to the terminal devices 4A to 4D, the communication unit 21 also transmits the information indicated by the tag TG3 to which the summary information tag has been added by the addition unit 236 to the terminal devices 4A to 4D.

[0032] Similarly, the communication processing unit 231 may notify the programmable display device 3 using the communication unit 21. Specifically, the communication unit 21 may transmit, via the BOT 6, to the programmable display device 3, information on the posting screen PP1 and information indicated by the tag TG3 to which the summary information tag has been added by the adding unit 236. Note that the display on the display unit 32 of the programmable display device 3 may also be maintained in the maintenance area A1.

[0033] In the terminal devices 4A to 4D, the communication unit 41 receives, from the communication unit 21 of the server 2, information on the posting screen PP1 and information indicated by the tag TG3 to which the summary information tag has been added by the adding unit 236. The control unit 44 determines whether the summary information tag has been added to the information indicated by the tag TG3.

[0034] Consider a case where the control unit 44 determines that a summary information tag has been added to the information indicated by the tag TG3. In this case, the control unit 44 displays information indicating that user A is unavailable to respond to the alarm as the information indicated by the tag TG3 in the response information I2 related to the maintenance area A1 of the posting screen PP1 displayed by the display unit 42.

[0035] The BOT 6 receives, from the communication unit 21 of the server 2, information on the posting screen PP1 and information indicated by the tag TG3 to which the summary information tag has been added by the adding unit 236. The BOT 6 determines whether the summary information tag has been added to the information indicated by the tag TG3.

[0036] In the programmable display device 3, the communication unit 31 may receive, from the communication unit 21 of the server 2 via the BOT 6, the information on the posting screen PP1 and the information indicated by the tag TG3 to which the summary information tag has been added by the adding unit 236. In this case, the control unit 34 determines whether the summary information tag has been added to the information indicated by the tag TG3.

[0037] Consider a case where the control unit 34 determines that a summary information tag is added to the information indicated by the tag TG3. In this case, the control unit 34 displays information indicating that user A is unavailable to respond to the alarm as the information indicated by the tag TG3 in the response information I2 related to the maintenance area A1 of the posting screen PP1 displayed by the display unit 32.

[0038] Messages M4 to M6 are posted in the same way as message M3. Consider the case where user B posts message M4. A tag TG4 is added to message M4. Tag TG4 is an alarm unavailable tag indicating that user B is unavailable to respond to the alarm. When message M4 is posted, information indicating that user B is unavailable to respond to the alarm is displayed as information indicated by tag TG4 in response information I2 displayed on display unit 42 of terminal devices 4A to 4D.

[0039] Now, consider the case where user C posts message M5. A tag TG5 is attached to message M5. The tag TG5 is an alarm response available tag indicating that user C is available to respond to the alarm. When message M5 is posted, information indicating that user C is available to respond to the alarm is displayed as information indicated by tag TG5 in response information I2 displayed on display unit 42 of terminal devices 4A to 4D.

[0040] Furthermore, consider the case where user B posts message M6. A tag TG6 is attached to message M6. The tag TG6 is an alarm response available tag indicating that user B is available to respond to the alarm. When message M6 is posted, information indicating that user B is available to respond to the alarm is displayed as information indicated by tag TG6 in response information I2 displayed on display unit 42 of terminal devices 4A to 4D.

[0041] In other words, when user B posts message M4 and then message M6, response information I2 is updated from information indicating that user B is unable to respond to the alarm to information indicating that user B is able to respond to the alarm.

[0042] Now, consider a case where a message M6 is posted from terminal device 4B to posting screen PP1 after communication unit 21 transmits information indicated by tag TG4 to which a summary information tag has been added by addition unit 236 to terminal devices 4A to 4D. In this case, processing by detection unit 233, collection unit 234, information generation unit 235, addition unit 236, and communication unit 21 is executed again, thereby updating response information I2 displayed in maintenance area A1.

[0043] Specifically, the detection unit 233 detects the tag TG6 from the message M6. The collection unit 234 acquires the tag TG6 detected by the detection unit 233. The information generation unit 235 generates a summary information tag, and the addition unit 236 adds the summary information tag generated by the information generation unit 235 to the information indicated by the tag TG6 acquired by the collection unit 234. The communication unit 21 transmits the information indicated by the tag TG6 to which the summary information tag has been added by the addition unit 236 to the terminal devices 4A to 4D.

[0044] In the terminal devices 4A to 4D, the communication unit 41 receives, from the communication unit 21 of the server 2, the information on the posting screen PP1 and the information indicated by the tag TG6 to which the summary information tag has been added by the adding unit 236. The control unit 44 determines whether the summary information tag has been added to the information indicated by the tag TG6.

[0045] Consider a case where the control unit 44 determines that a summary information tag has been added to the information indicated by the tag TG6. In this case, the control unit 44 updates the response information I2 related to the maintenance area A1 of the posting screen PP1 displayed by the display unit 42 from information indicating that user B is unavailable to respond to the alarm to information indicating that user B is available to respond to the alarm. This allows the users of the terminal devices 4A to 4D to check the latest related information related to the alarm at a glance.

[0046] <(2) tag> The alarm occurrence tag is a tag indicating that an alarm has occurred. The alarm occurrence tag is added to a message sent from the BOT 6 to the server 2. For example, if an abnormality occurs in the device 8, the PLC 7 sends abnormality information indicating that an abnormality has occurred in the device 8 and variable information indicating variables related to the device 8 to the programmable display device 3.

[0047] In the programmable display device 3, when the communication unit 31 receives the abnormality information and variable information from the PLC 7, the control unit 34 uses the communication unit 31 to transmit the abnormality information and variable information to the BOT 6. When the BOT 6 receives the abnormality information and variable information from the communication unit 31 of the programmable display device 3, it detects and collects information related to the alarm from the abnormality information and variable information, and generates information related to the abnormality information and variable information.

[0048] Then, the BOT 6 transmits a message M1 shown in Fig. 2 to the server 2. The message M1 includes occurrence information I1 indicating the occurrence of an alarm and a tag TG1. The occurrence information I1 may include the time when the alarm occurred. The tag TG1 is an alarm occurrence tag indicating that an alarm has occurred.

[0049] In the server 2, the communication processing unit 231 receives a message M1 from the BOT 6 using the communication unit 21. The detection unit 233 detects a tag TG1 from the message M1 received by the communication unit 21. The information generation unit 235 generates a summary information tag for displaying the information indicated by the tag TG1 in the maintenance area A1. The information indicated by the tag TG1 is an example of occurrence information indicating the occurrence of an alarm. Furthermore, the summary information tag for displaying the information indicated by the tag (2) above, such as the tag TG1, is an example of second information.

[0050] The addition unit 236 adds the summary information tag generated by the information generation unit 235 to the information indicated by the tag TG1. The storage processing unit 232 updates the posting screen PP1 stored in the storage unit 22 by adding the message M1. At this time, the storage processing unit 232 also stores in the storage unit 22 the information indicated by the tag TG1 to which the summary information tag has been added by the addition unit 236.

[0051] The communication processing unit 231 notifies the terminal devices 4A to 4D using the communication unit 21. At this time, the communication unit 21 transmits information on the posting screen PP1 stored in the storage unit 22 to the terminal devices 4A to 4D. A message M1 has been added to the posting screen PP1, and the message M1 includes the tag TG1. Therefore, by transmitting the information on the posting screen PP1 to the terminal devices 4A to 4D, the communication unit 21 also transmits the information indicated by the tag TG1 to which the summary information tag has been added by the addition unit 236 to the terminal devices 4A to 4D. In other words, the communication unit 21 transmits the summary information tag generated by the information generation unit 235 to the terminal devices 4A to 4D.

[0052] Similarly, the communication processing unit 231 may use the communication unit 21 to notify the programmable display device 3 via the BOT 6. Specifically, the communication unit 21 may transmit, to the programmable display device 3 via the BOT 6, information on the posting screen PP1 and information indicated by the tag TG1 to which the summary information tag has been added by the addition unit 236.

[0053] The communication unit 21 transmits a summary information tag to the terminal devices 4A to 4D for displaying occurrence information indicating the occurrence of an alarm in the maintenance area A1 where the display on the display unit 42 of the terminal devices 4A to 4D is maintained. This allows the users of the terminal devices 4A to 4D to check the occurrence information indicating the occurrence of an alarm at a glance.

[0054] In the terminal devices 4A to 4D, the communication unit 41 receives, from the communication unit 21 of the server 2, information on the posting screen PP1 and information indicated by the tag TG1 to which the summary information tag has been added by the adding unit 236. The control unit 44 determines whether the summary information tag has been added to the information indicated by the tag TG1.

[0055] Consider a case where the control unit 44 determines that a summary information tag has been added to the information indicated by the tag TG1. In this case, the control unit 44 displays a message M1 in the maintenance area A1 of the posting screen PP1 displayed by the display unit 42. Note that the BOT 6 may also transmit to the server 2 a message regarding an alarm, a message displaying a trend graph, or a message showing the results of a compilation of the response status to the alarm.

[0056] <(3) tag> The alarm recovery tag is a tag indicating that an alarm has been recovered. The alarm recovery tag is added to a message sent from the BOT 6 to the server 2. For example, when an abnormality in the device 8 is recovered, the PLC 7 sends recovery information indicating that the abnormality in the device 8 has been recovered to the programmable display device 3.

[0057] In the programmable display device 3, when the communication unit 31 receives recovery information from the PLC 7, the control unit 34 uses the communication unit 31 to transmit the recovery information to the BOT 6. When the BOT 6 receives the recovery information from the communication unit 31 of the programmable display device 3, it transmits a message M7 shown in FIG. 2 to the server 2. The message M7 includes recovery information I3 indicating the recovery of the alarm and a tag TG7. The recovery information I3 may also include the time of recovery of the alarm. The tag TG7 is an alarm recovery tag.

[0058] In the server 2, the communication processing unit 231 receives a message M7 from the BOT 6 using the communication unit 21. The detection unit 233 detects a tag TG7 from the message M7 received by the communication unit 21. The information indicated by the tag TG7 is an example of recovery information indicating that an alarm has been recovered. The storage processing unit 232 updates the posting screen PP1 stored in the storage unit 22 to add the message M7. At this time, the storage processing unit 232 also stores the information indicated by the tag TG7 in the storage unit 22.

[0059] The communication processing unit 231 notifies the terminal devices 4A to 4D using the communication unit 21. At this time, the communication unit 21 transmits the information of the posting screen PP1 stored in the storage unit 22 to the terminal devices 4A to 4D. As a result, the communication unit 21 also transmits the information indicated by the tag TG7 to the terminal devices 4A to 4D. Similarly, the communication processing unit 231 may also notify the programmable display device 3 via the BOT 6 using the communication unit 21. Specifically, the communication unit 21 may transmit the information of the posting screen PP1 and the information indicated by the tag TG7 to the programmable display device 3 via the BOT 6.

[0060] In the terminal devices 4A to 4D, the communication unit 41 receives information on the posting screen PP1 and information indicated by the tag TG7 from the communication unit 21 of the server 2. The control unit 44 determines whether a summary information tag has been added to the information indicated by the tag TG7. The control unit 44 determines that a summary information tag has not been added to the information indicated by the tag TG7, and causes the display unit 32 to display a message M7 in an area of ​​the posting screen PP1 other than the maintenance area A1.

[0061] In the programmable display device 3, the communication unit 31 may receive information on the posting screen PP1 and information indicated by the tag TG7 from the communication unit 21 of the server 2. In this case, the control unit 34 determines whether a summary information tag has been added to the information indicated by the tag TG7. The control unit 34 determines that a summary information tag has not been added to the information indicated by the tag TG7, and causes the display unit 32 to display the message M7 in an area of ​​the posting screen PP1 other than the maintenance area A1.

[0062] <(4) tag> The response status request tag is a tag that requests information indicating the response status to the alarm. Specifically, the response status request tag is a tag that requests information indicating the response status to the alarm for each user. The response status request tag is added to messages transmitted from the terminal devices 4A to 4D to the server 2. When posting a message, users A to D can operate the operation unit 43 to include the response status request tag in the message.

[0063] When a message including a response status request tag is posted on the posting screen PP1, the detection unit 233 detects the response status request tag from the message. When the detection unit 233 detects the response status request tag, the information generation unit 235 generates first request information that requests that the information indicated by the tag collected by the collection unit 234 (information indicating the response status in response to the alarm) be displayed on the display units 42 of the terminal devices 4A to 4D.

[0064] The communication processing unit 231 of the server 2 transmits the first request information generated by the information generating unit 235 to the terminal devices 4A to 4D using the communication unit 21. When the communication unit 41 of the terminal devices 4A to 4D receives the first request information from the communication unit 21, the control unit 44 causes the display unit 42 to display information indicating the response status to the alarm on the posting screen PP1.

[0065] Note that a message including an information request tag requesting detailed information about the alarm that has occurred may be posted on the posting screen PP1 as an example of the response status request tag. In this case, the information generating unit 235 generates second request information requesting detailed information about the alarm.

[0066] The communication processing unit 231 of the server 2 uses the communication unit 21 to transmit the second request information generated by the information generation unit 235 to the BOT 6. The BOT 6 transmits the second request information received from the communication unit 21 to the programmable display device 3. In the programmable display device 3, when the communication unit 31 receives the second request information from the BOT 6, the control unit 34 uses the communication unit 31 to have the PLC 7 read out the status of the device 8 and receives information indicating the status of the device 8 from the PLC 7.

[0067] The control unit 34 uses the communication unit 31 to transmit the information indicating the status of the device 8 received from the PLC 7 to the server 2 via the BOT 6. The communication unit 21 receives the information indicating the status of the device 8 from the BOT 6. The information generation unit 235 generates third request information that requests that the information indicating the status of the device 8 be displayed on the posting screen PP1 displayed by the display unit 42.

[0068] The communication processing unit 231 uses the communication unit 21 to transmit the third request information generated by the information generation unit 235 to the terminal devices 4A to 4D. When the communication unit 41 receives the third request information from the communication unit 21 in the terminal devices 4A to 4D, the control unit 44 causes the display unit 42 to display information indicating the status of the device 8 on the posting screen PP1. Here, the information indicating the status of the device 8 may be included in the third request information and is detailed information about the alarm that has occurred, such as a trend of numerical values ​​related to the alarm or a method for restoring the alarm.

[0069] <(5) tag> The summary information tag is a tag for displaying response information I2 indicating whether users A to D are able to respond to the alarm and the status of the alarm. For example, consider a case where the detection unit 233 detects a tag TG1 from a message M1 received by the communication unit 21 from a BOT 6. In this case, the information generation unit 235 generates a summary information tag for displaying the message M2 in the maintenance area A1.

[0070] Message M2 includes response information I2 indicating whether users A to D are able to respond to the alarm. Response information I2 is an example of related information related to the alarm that has occurred. Addition unit 236 adds a summary information tag generated by information generation unit 235 to message M2. Storage processing unit 232 updates posting screen PP1 stored in storage unit 22 to add message M2. At this time, storage processing unit 232 also stores the summary information tag in storage unit 22.

[0071] The communication processing unit 231 notifies the terminal devices 4A to 4D using the communication unit 21. At this time, the communication unit 21 transmits the information of the posting screen PP1 stored in the storage unit 22 to the terminal devices 4A to 4D. As a result, the communication unit 21 also transmits the summary information tag to the terminal devices 4A to 4D. Similarly, the communication processing unit 231 may also notify the programmable display device 3 via the BOT 6 using the communication unit 21. Specifically, the communication unit 21 may transmit the information of the posting screen PP1 to the programmable display device 3.

[0072] In the terminal devices 4A to 4D, when the communication unit 41 receives information on the posting screen PP1 from the communication unit 21 of the server 2, the control unit 44 determines whether a summary information tag has been added to the message M2. The control unit 44 determines that a summary information tag has been added to the message M2, and causes the display unit 42 to display the message M2 in the maintenance area A1 of the posting screen PP1.

[0073] Furthermore, in the programmable display device 3, when the communication unit 31 receives information on the posting screen PP1 from the communication unit 21 of the server 2, the control unit 34 determines whether a summary information tag has been added to the message M2. The control unit 34 determines that a summary information tag has been added to the message M2, and causes the display unit 32 to display the message M2 in the maintenance area A1 of the posting screen PP1.

[0074] Now, consider the time when the communication unit 41 of the terminal devices 4A to 4D receives the message M2 from the communication unit 21 of the server 2. At this time, if the posting screen PP1 is not displayed on the display unit 42 of the terminal devices 4A to 4D, the response information of all of the users A to D in the response information I2 indicates that no response has been made. The detection unit 233 detects that no response has been made when no message has been posted from the terminal devices 4A to 4D.

[0075] As described above, the information generation unit 235 generates a summary information tag for each of the terminal devices 4A to 4D to display the related information collected by the collection unit 234 in the maintenance area A1 of the posting screen PP1, in which the display on the display unit 42 of the terminal devices 4A to 4D is maintained. Furthermore, the addition unit 236 adds the summary information tag generated by the information generation unit 235 to the related information collected by the collection unit 234. The communication unit 21 transmits the related information to which the summary information tag has been added by the addition unit 236 to the terminal devices 4A to 4D.

[0076] The communication unit 21 transmits the alarm-related information, to which the summary information tag has been added, to the terminal devices 4A to 4D. The summary information tag is information that causes each of the multiple terminal devices 4A to 4D to display the alarm-related information in the maintenance area A1 in which the display on the display unit 42 of the terminal devices 4A to 4D is maintained. Therefore, the alarm-related information is displayed in the maintenance area A1 on the display unit 42 of the terminal devices 4A to 4D. Therefore, the users of the terminal devices 4A to 4D can check at a glance the alarm-related information collected based on messages that can be posted on the posting screen PP1, without having to check the individual messages posted on the posting screen PP1.

[0077] Furthermore, the detection unit 233 detects, from the message, response information I2 indicating whether the users of the terminal devices 4A to 4D are able to respond to the alarm, as related information. The related information detected by the detection unit 233 is response information I2 indicating whether the users of the terminal devices 4A to 4D are able to respond to the alarm.

[0078] Therefore, because the response information I2 is displayed in the maintenance area A1, the users of the terminal devices 4A to 4D can check at a glance the response information collected based on messages that can be posted on the posting screen PP1. In other words, each user can check at a glance the response status of others and instantly determine whether or not they need to respond to the alarm.

[0079] <Displaying the history of past alarms> Fig. 3 is a diagram showing an example of a case where a history AC1 of past alarms is displayed on the posting screen PP1 shown in Fig. 2. Consider a case where the detection unit 233 detects a tag TG7 indicating alarm recovery from the message M7 shown in Fig. 2. In this case, the information generation unit 235 generates third information for displaying a message M8 including a history AC1 of past alarms that have been historically recorded for the alarm in the maintenance area A1. The history AC1 of past alarms indicates, for example, the time when an alarm occurred in the past and the time when the alarm was recovered in the past.

[0080] The storage processing unit 232 updates the posting screen PP1 stored in the storage unit 22 by adding the message M8. The communication processing unit 231 notifies the terminal devices 4A to 4D using the communication unit 21. At this time, the communication unit 21 transmits the information of the posting screen PP1 stored in the storage unit 22 to the terminal devices 4A to 4D. The communication unit 21 also transmits the third information generated by the information generation unit 235 to the terminal devices 4A to 4D.

[0081] The communication unit 21 transmits the third information for displaying the past alarm history AC1 in the maintenance area A1 to the terminal devices 4A to 4D, so that the users of the terminal devices 4A to 4D can check the past alarm history AC1 at a glance.

[0082] After the posting screen PP1 is updated to add message M8, when the communication unit 21 receives message M1 from BOT 6, messages M1, M2, and M8 are displayed in the maintenance area A1. The information generation unit 235 may generate third information so that alarm histories older than a predetermined time before the current time are not displayed in the maintenance area A1. No summary information tag is added to message M8.

[0083] The third information may also be information for displaying a message M8 including link information for displaying a past alarm history AC1 in the maintenance area A1. In this case, when users A to D operate the operation unit 43 to select the link information included in the message M8, the control unit 44 causes the display unit 42 to display the past alarm history AC1. Note that adding the past alarm history AC1 to the posting screen PP1 may move the position of the response information indicating whether or not the user can respond.

[0084] <Selection screen PP2> Fig. 4 is a diagram showing an example of a selection screen PP2 showing a list of threads that can be displayed on the display units 42 of the terminal devices 4A to 4D included in the management system 100 shown in Fig. 1. For example, when a user operates the operation unit 43 to select a thread SL1 on the selection screen PP2, the control unit 44 causes the display unit 42 to display a posting screen PP1 shown in Fig. 2. Similarly, when another thread is selected, a posting screen corresponding to that thread is displayed on the display unit 42.

[0085] The creation unit of the server 2 creates a thread for each programmable display device 3 and each type of alarm, and the setting unit sets a group of users who can receive messages for each thread. In other words, the setting unit sets a group of terminal devices that can receive messages for each thread. The creation unit and setting unit are provided in the control unit 23. Users who belong to a group that can receive messages can communicate about responses to alarms through the posting screen PP1.

[0086] Here, the information generating unit 235 generates fourth request information that requests that the selection screen PP2 be displayed on the display unit 42 of the terminal device 4A to 4D. The selection screen PP2 is a screen that allows the user to select one thread from among the threads for displaying a posting screen corresponding to each of a plurality of alarms. A thread is an example of a selection area. The fourth request information includes a list of the threads that the terminal device 4A to 4D should display, and each item in the list includes the display name of the thread (alarm name) and the status of the alarm (occurring / recovered / responded, etc.).

[0087] The communication unit 21 transmits the fourth request information generated by the information generation unit 235 to the terminal devices 4A to 4D. On the selection screen PP2, the display priority of the selection area of ​​the posting screen corresponding to an alarm in which the event that caused the alarm to be generated is still present is higher than the display priority of the selection area of ​​the posting screen corresponding to an alarm in which the event that caused the alarm to be generated has been resolved. The display priority is expressed, for example, by the display order or the color of the thread.

[0088] For example, consider a case where an alarm occurrence tag is detected by detection unit 233 on posting screen PP1 corresponding to thread SL1. In this case, control unit 44 of terminal devices 4A to 4D changes the color of thread SL1 to a color corresponding to the occurrence of an alarm, based on the fourth request information received by communication unit 41 from communication unit 21. Furthermore, each thread may display the number of unreplied users indicating the number of users who have not responded to the posting screen corresponding to the thread.

[0089] Also, consider a case where an alarm response possible tag is detected on the posting screen corresponding to thread SL2 by the detection unit 233. In this case, the control unit 44 of the terminal devices 4A to 4D changes the color of thread SL2 to a color corresponding to the alarm being handled, based on the fourth request information received by the communication unit 41 from the communication unit 21.

[0090] Furthermore, consider a case where an alarm reset tag is detected on the posting screen corresponding to thread SL3 by the detection unit 233. In this case, the control unit 44 of the terminal devices 4A to 4D changes the color of thread SL3 to a color corresponding to the alarm being reset, based on the fourth request information received by the communication unit 41 from the communication unit 21.

[0091] On the selection screen PP2, for example, regardless of the number of unanswered messages on the posting screen, threads may be displayed in darker colors in the order of alarm occurrence, alarm being handled, and alarm recovery. Also, on the selection screen PP2, threads may be displayed from the top in the order of alarm occurrence, alarm being handled, and alarm recovery. In this way, by changing the color and display order of threads based on the tags detected by the detection unit 233, it is possible to make it easier to grasp currently occurring alarms.

[0092] The users of the terminal devices 4A to 4D can check the display priority of the selection areas on the posting screen corresponding to each of the multiple alarms, and can therefore preferentially select the selection area on the posting screen corresponding to the alarm for which the event that caused the alarm to occur is still being maintained.

[0093] In addition, the user can determine whether the alarm corresponding to each thread is currently active, currently being handled, or has been resolved simply by checking the threads on the selection screen PP2. Furthermore, even if there are a large number of threads, the current alarm status can be easily grasped on the selection screen PP2.

[0094] <Another example of posting a message> Fig. 5 is a diagram showing an example of posting a message on the posting screen PP1 shown in Fig. 2. When displaying the posting screen PP1 on the display unit 42, the control unit 44 causes an input field IP1 for inputting a message, a standard button B1, and a send button B2 to be displayed on the display unit 42, as shown in Fig. 5. Users A to D can input a message in the input field IP1 by operating the operation unit 43, and when they press the standard button B1, the control unit 44 causes a selection display DS1 to be displayed on the display unit 42.

[0095] The selection display DS1 displays the standard phrases "unavailable," "available," and "graph display." Users A to D can select these standard phrases by operating the operation unit 43. The selection display DS1 displays a plurality of standard phrases. When "unavailable" is selected, "unavailable" is entered into the input field IP1, and when "available" is selected, "available" is entered into the input field IP1. When "graph display" is selected, "graph display" is entered into the input field IP1.

[0096] Users A to D can post a message on the posting screen PP1 by operating the operation unit 43 and pressing the send button B2. If "unavailable" is selected, an alarm unavailable tag is added to the posted message, and if "available" is selected, an alarm available tag is added to the posted message. In this way, users A to D can send a message simply by selecting a fixed phrase from the selection display DS1. In other words, users A to D can save the trouble of inputting a message and also the trouble of adding tags to the message.

[0097] Furthermore, when users A to D operate the operation unit 43 to select "Graph display" from the selection display DS1 and post a message, an information request tag is added to the message, requesting information for graph display from the programmable display device 3. As a result, a message M9 including content indicating "Graph display" and the time the message was posted is posted on the posting screen PP1, and a message M10 showing a graph related to the device 8 is posted from the server 2.

[0098] <Effects> The management system 100 uses a group chat system for alarm notification, and links alarms with the response contact after an alarm occurs. This allows seamless communication from alarm notification to response (such as communication about who can rush to the scene), and a log of this communication can be kept.

[0099] In addition, it is possible to quickly find the thread of an alarm that has occurred, and to check at a glance whether the person in question is available to respond, which requires checking past logs. Furthermore, this information can be used to prepare countermeasures for future alarm occurrences.

[0100] In the management system 100, a user can immediately determine who in the group can respond to an alarm while communicating with other users in the group in order to respond to the alarm. Furthermore, even after a user who can respond to an alarm arrives at the scene where the alarm occurred, the user can consult with other users on how to respond to the alarm or request assistance from the scene.

[0101] Furthermore, when communicating with other users, there is no need to use a separate chat app or call app, and communication with other users can be easily achieved. Alarm occurrence status and response status can be smoothly shared, and unlike separate chat apps and calls, alarm history can be kept. Furthermore, users do not need to go back through other users' messages on the posting screen PP1 to check the alarm status, and there is no need to refer to all past logs, so they can immediately determine the alarm response status.

[0102] <Variation 1> Regarding tags that are added to messages posted on the posting screen PP1, there may be tags that can only be added by the programmable display device 3 or the server 2, and tags that can only be added by some users. In other words, authority for tags may be set for each programmable display device 3, server 2, and user. This makes it possible to prevent, for example, a user from accidentally adding a tag and changing the status of an alarm.

[0103] <Variation 2> The management system 100 may include a plurality of programmable display devices 3. In this case, the server 2 communicates with the plurality of programmable display devices 3. The server 2 executes the above-described processing between the server 2 and the plurality of programmable display devices 3.

[0104] [Embodiment 2] A second embodiment of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the first embodiment, and the description thereof will not be repeated.

[0105] Fig. 6 is a block diagram showing an example of the configuration of a management system 100A according to the second embodiment of the present invention. As shown in Fig. 6, the management system 100A differs from the management system 100 in that the management device 1 is changed to a management device 1A, and the management device 1A differs from the management device 1 in that the server 2 is changed to a server 2A.

[0106] Server 2A differs from server 2 in that control unit 23 is replaced with control unit 23A. Control unit 23A includes a model generation unit 237 in addition to the components included in control unit 23. Model generation unit 237 receives content information indicating the content of messages posted on posting screen PP1 from terminal devices 4A to 4D as input, and generates a detection model through machine learning that outputs related information relating to an alarm that has occurred. In other words, model generation unit 237 generates a detection model through supervised learning using a dataset that is a combination of a plurality of example conversation sentences and the intentions indicated by those example sentences.

[0107] For example, the model generation unit 237 generates a detection model by machine learning using response information indicating whether the users of the terminal devices 4A to 4D are able to respond to the alarm as the related information related to the alarm. The content information indicating the content of the message is, for example, text information.

[0108] The detection unit 233 detects related information relating to the generated alarm from messages posted on the posting screen PP1 from the terminal devices 4A to 4D, using the detection model generated by the model generation unit 237. For example, the detection unit 233 detects response information indicating whether the users of the terminal devices 4A to 4D are able to respond to the alarm, from the messages, using the detection model generated by the model generation unit 237.

[0109] The detection unit 233 uses a detection model generated by machine learning to detect related information related to the alarm from messages that can be posted from the terminal devices 4A to 4D. Therefore, it is possible to detect related information from a message without adding additional information indicating the related information to the message. In other words, there is no need to add a tag to the message.

[0110] [Software implementation example] The functions of the management device 1, 1A (hereinafter referred to as the "device") can be realized by a program that causes a computer to function as the device, and a program that causes a computer to function as each control block of the device (particularly each part included in the control unit 23, 23A).

[0113] Furthermore, some or all of the functions of the control blocks can be realized by logic circuits. For example, an integrated circuit in which a logic circuit that functions as each of the control blocks is formed is also included in the scope of the present invention. In addition, the functions of the control blocks can also be realized by, for example, a quantum computer.
