JP7673783B2 - Notification management system, communication system, notification management method, and program - Google Patents

Description

The present invention relates to a notification management system, a communication system, a notification management method, and a program.

At production sites, etc., when workers performing assembly work on a line report an abnormality or trouble to the line manager, a rotating light installed on the line lights up and a buzzer sounds to notify them. Another solution for this type of communication is a communication system where the line number is displayed on an electronic bulletin board when a button is pressed on the line.

In addition, a communication system is known in which, in a communication device such as an intercom, an image of a visitor on the intercom is sent to a mobile terminal in response to a call from the intercom so that the caller can be confirmed before answering (see, for example, Patent Document 1).

In conventional systems, at production sites, managers are unable to rush to the site until they hear the buzzer or notice the information on the electronic bulletin board, and as they are only able to understand and respond to the problem once they have arrived at the site, it can take time to respond to the problem. In addition, the details of the problem that has occurred cannot be shared with other managers, for example, until the manager has responded to the problem and recorded it, making it difficult for multiple managers to split up and respond to multiple problems when they occur.

Thus, in conventional systems, for example, there is a problem in that managers at production sites and other sites are unable to quickly respond to events (such as problems) that occur. Note that such problems are difficult to resolve simply by applying the technology disclosed in Patent Document 1, for example.

One embodiment of the present invention has been made in consideration of the above problems, and enables managers and others to quickly respond to events that occur at production sites and other worksites.

In order to solve the above problem, a notification management system according to one embodiment of the present invention is a notification management system connected via a communication network to a first terminal device used by an on-site worker and a second terminal device used by an administrator, and includes a setting information management means for transmitting a setting screen for accepting settings of setting information including options for a plurality of events to an information terminal capable of communicating with the notification management system and accepting the setting of the setting information from the information terminal; and a first screen displayed on the first terminal device using the setting information acquired from the notification management system , the first screen allowing the worker to select an event that has occurred from the plurality of events. the event information being information on the occurred event transmitted from the first terminal device when the event information is selected, a first transmission means for transmitting the received event information to the second terminal device, a second reception means for receiving a response transmitted from the second terminal device when an event to which the manager will respond is selected via a second screen displayed on the second terminal device, the second screen displaying an event that has occurred at the site based on the transmitted event information, and a second transmission means for transmitting the received response to the first terminal device so that the first terminal device can display that the event that has occurred is being handled by the manager.

According to one embodiment of the present invention, managers and others can quickly respond to events that occur at production sites and other work sites.

<System Configuration>
1 is a diagram showing an example of a system configuration of a communication system according to an embodiment. The communication system 1 includes a notification management system 10 connected to a communication network 2 such as the Internet or a LAN (Local Area network), one or more first terminal devices 101a, 101b, ..., and one or more second terminal devices 102a, 102b, ..., etc.

In the following description, when referring to any one of the one or more first terminal devices 101a, 101b, ..., the term "first terminal device 101" is used. When referring to any one of the one or more second terminal devices 102a, 102b, ..., the term "second terminal device 102" is used. Furthermore, the first terminal device 101 and the second terminal device 102 may be collectively referred to simply as "terminal device".

The first terminal device 101 is an information processing device having a computer configuration such as a smartphone, tablet terminal, or dedicated terminal, which is placed at a site 30 where workers perform work, such as a production site, repair site, or packaging site. The first terminal device 101 executes a predetermined application program (hereinafter referred to as an app) to display an operation screen on a display unit such as a touch panel display, which selectably displays one or more events corresponding to the site 30. Here, the one or more events corresponding to the site 30 may include various occurrences that may occur at the site 30, such as "toilet," "out of parts," and "line stopped."

The second terminal device 102 is an information processing device having a computer configuration such as a smartphone, tablet terminal, or dedicated terminal, which is used by a manager or the like who manages the site 30. The second terminal device 102 displays on the display unit a notification screen that notifies the occurrence of information about an event occurring at the site 30 based on information about an event selected by a worker or the like on the first terminal device 101.

The notification management system 10 is, for example, an information processing device having a computer configuration, or a system including multiple information processing devices, and includes, for example, an administration site 11, a user site 12, and an API (Application Programming Interface) 13. The notification management system 10 also includes a log information DB (Database) 14 and a setting information DB 15 inside or outside the notification management system 10. The notification management system 10 is, for example, placed on a cloud, but is not limited to this, and may be realized, for example, by a server device placed in a local network.

The management site 11 is a website for registering, in the setting information DB 15, setting information for setting the display screen displayed on the display unit of the first terminal device 101 or the display screen displayed on the second terminal device 102. The administrator, etc. can set the setting information by accessing the management site 11 using an information terminal 100 having a web browser function, such as a PC (Personal Computer), a tablet terminal, or a smartphone. The management site 11 stores and manages the set setting information in the setting information DB 15. Note that the administrator, etc. may access the management site 11 using a web browser provided on the first terminal device 101 or the second terminal device 102, for example, without being limited to the information terminal 100.

The user site 12 is a website that provides the log information stored in the log information DB 14 to the administrator, etc. The administrator, etc. can access the user site 12 using an information terminal 100, etc. that has a web browser function, and display the log information of the notification management system 10 stored in the log information DB 14 on the display unit, etc. of the information terminal 100.

The API 13 provides an interface for using various functions of the notification management system 10 to the first terminal device 101 and the second terminal device 102, etc. For example, the API 13 provides the terminal devices, etc. with a Web API for using various functions including a function for logging in to the notification management system 10, a function for acquiring setting information, a function for transferring information, and a function for recording responses to events.

The notification management system 10 uses, for example, an authentication infrastructure 20 external to the communication system 1 to authenticate users (administrators, workers, etc.) or terminal devices (first terminal device 101, second terminal device 102, etc.) who use the notification management system 10. This allows the notification management system 10 to identify users or terminal devices that have logged in to the notification management system 10.

(Processing Overview)
2 is a diagram for explaining an overview of the process of the communication system according to an embodiment. In FIG. 2, the first terminal device 101 arranged at the site 30 displays an operation screen 201 that selectably displays one or more events (e.g., "toilet", "out of parts", etc.) corresponding to the site 30. In the example of FIG. 2, the operation screen 201 displays a selection area 202 that displays a plurality of selection buttons for selecting events such as "toilet", "out of parts", etc., an installation location display area 203 that displays an installation location, and a status display area 204 that displays a status. The number of the plurality of selection buttons displayed in the selection area 202, the display contents, etc. can be customized by an administrator or the like by accessing the management site 11 with the information terminal 100 or the like and changing the setting information.

In addition, in FIG. 2, the site manager 211 who manages the site 30 possesses the second terminal device 102a, and the parts manager 212 who manages the parts possesses the second terminal device 102b. In the following explanation, the site manager 211 and the parts manager 212 may be collectively referred to simply as the manager. In the example of FIG. 2, the replacement personnel 213 possesses the second terminal device 102c. In this way, the second terminal device 102 may be possessed by staff other than the manager.

In the above configuration, for example, when a problem occurs at the site 30, the worker 200 selects a selection button corresponding to the problem that occurred at the site 30 from among a plurality of selection buttons displayed in the selection area 202 of the first terminal device 101 (step S1). As a result, the first terminal device 101 transmits information on the event selected by the worker 200 (herein referred to as event information) to the notification management system 10 (step S2).

When the notification management system 10 receives event information from the first terminal device 101, it displays, for example, in the status display area 204 of the operation screen 201 displayed by the first terminal device 101, that the administrator is being called (step S3). At this time, the notification management system 10 may turn on the rotating light 205 provided at the site 30 to notify that a problem has occurred at the site 30. Note that the processing of step S3 is optional. For example, when the first terminal device 101 transmits event information to the notification management system 10, it may display in the status display area 204 that the administrator is being called, without being controlled by the notification management system 10.

The notification management system 10 records log information indicating that the event information has been received from the first terminal device 101 in the log information DB 14 (step S4), and transfers the received event information to the second terminal device 102a, 102b, etc., possessed by the administrator (step S5). Preferably, the notification management system 10 pushes the event information received from the first terminal device 101 to the second terminal device 102a, 102b, etc., possessed by the administrator. As a result, a notification screen indicating that the event selected by the worker 200 is occurring at the site 30 is displayed on the display screen of the second terminal device 102a, 102b.

The manager who receives the notification responds according to the content of the event occurring at the site 30, for example, as displayed on the notification screen. For example, if the event occurring at the site 30 is "other," the site manager 211 responds by rushing to the site 30 or by making a voice call with the worker 200 at the site 30 to instruct the worker to respond. Also, if the event occurring at the site 30 is "toilet," the site manager 211 may transfer the event information to the second terminal device 102c of the replacement worker 213 as necessary and instruct the replacement (step S6). Also, if the event occurring at the site 30 is "out of parts," the parts manager 212 may arrange for parts to be replenished.

When the administrator has finished responding to the event occurring at the site 30, the administrator can send the response details to the notification management system 10 by inputting the response details into the second terminal device 102 (step S7). When the notification management system 10 receives the response details from the second terminal device 102, it records the received response details in the log information DB 14, for example, in association with the event that occurred at the site 30.

For example, by performing the above-described processing, the communication system 1 according to this embodiment enables a manager or the like to quickly respond to an event that occurs at a site 30, such as a production site.

As shown in Figure 6 (C), the business item 602 includes information such as a business item ID, a business item name, a type, and options as keys (items). The business item ID is identification information for identifying the business item 602. The business item name is information indicating the name of the business item. For example, information such as options, photos, text, and lists is set as the type. For example, information regarding the options of the setting item is set as the option.

Fig. 7 (A) shows an example of data to be set in the work information 601 according to one embodiment, and Fig. 7 (B) shows an example of data to be set in the work item 602 according to one embodiment. For example, the work item IDs "item1" and "item2" are set for the work with the work ID "work1" in Fig. 7 (A). The work item ID "item1" indicates an event option as shown in Fig. 7 (B), and the first terminal device 101 can display the operation screen 201 as shown in Fig. 2 using information such as toilet, out of parts, ..., etc., set in the options of the work item ID "item1". In addition, the work item ID "item2" indicates a list of forwarding destinations 1 as shown in Fig. 7 (B), and the notification management system 10 notifies the second terminal devices 102a and 102b of the event information using information such as user1, user2, etc., set in the options of the work item ID "item2".

In addition, the task with task ID "work3" in FIG. 7(A) has task item ID "item3" set.

Note that user1, user2, and user3 each indicate the user ID of the user using the second terminal device 102a, 102b, 102c, or the terminal ID for identifying the second terminal device 102a, 102b, 102c, etc.

<Processing flow>
Next, the process flow of the notification management method according to this embodiment will be described.

(Communication System Processing)
8 and 9 are sequence diagrams showing an example of processing of the communication system according to the first embodiment. Here, for example, as shown in Fig. 5, the communication system 1 includes a notification management system 10, a first terminal device 101, and a second terminal device 102, and a user who uses the first terminal device 101 is called an operator, and a user who uses the second terminal device 102 is called an administrator. Also, at the start of the processing shown in Fig. 8, it is assumed that the administrator has already logged in to the notification management system 10 using the second terminal device 102.

When the worker performs a startup operation on the first terminal device 101 in step S801, the first terminal device 101 executes a login process to log in to the notification management system 10 in step S802. This login process may be any method, but as an example, the display control unit 512 of the first terminal device 101 sends a login request to the notification management system 10. This login request may be, for example, a request to log in using the terminal ID of the first terminal device 101, or a login request using the user ID of the worker.

If the login request contains valid authentication information issued by the authentication infrastructure 20, the authentication unit 504 of the notification management system 10 permits the first terminal device 101 to log in. On the other hand, if the login request does not contain valid authentication information issued by the authentication infrastructure 20, the authentication unit 504 instructs the first terminal device 101 to redirect to the authentication infrastructure 20. In this case, the first terminal device 101 performs authentication, for example, OAuth or OpenID, in the authentication infrastructure 20, and after obtaining valid authentication information, sends a login request to the notification management system 10, thereby being able to log in to the notification management system 10.

In step S803, the display control unit 512 of the first terminal device 101 transmits a setting information acquisition request to the notification management system 10 to request acquisition of setting information. This acquisition request includes, for example, a template ID that identifies the template 600 that stores the setting information of the first terminal device 101.

In steps S804 and S805, when the reception unit 502 of the notification management system 10 receives a request to acquire setting information, it acquires setting information (template 600) corresponding to the template ID included in the request to acquire setting information from the setting information DB 15. In addition, in step S806, the reception unit 502 transmits the acquired setting information to the first terminal device 101. This setting information includes, for example, business information 601 in which data such as that shown in FIG. 7 (A) is set, and business items 602 in which data such as that shown in FIG. 7 (B) is set.

In step S807, the display control unit 512 of the first terminal device 101 uses the setting information acquired from the notification management system 10 to display, for example, an operation screen 1001 as shown in FIG. 10 (A) on a display unit such as the display 417.

In the example of FIG. 10(A), the operation screen 1001 includes an installation location display area 1002 that displays the installation location of the first terminal device 101, a status display area 1003 that displays the status, and a selection area 1004 that displays multiple selection buttons. The display control unit 512 uses the setting information acquired from the notification management system 10 to display multiple selection buttons in the selection area 1004 that selectably display events corresponding to the site 30, such as "toilet," "out of parts," ....

In step S808, when the worker performs a selection operation to select one of the multiple selection buttons displayed on the operation screen 1001, the communication system 1 executes the processing from step S809 onwards. For example, when a part is out of stock at the site 30, the worker selects the "Out of stock" button displayed on the operation screen 1001.

In step S809, the display control unit 512 of the first terminal device 101 displays, for example, a calling screen 1010 as shown in FIG. 10 (B) on a display unit such as the display 417. For example, the display control unit 512 highlights the selected "Out of Component" button 1012 in the selection area 1004 of the calling screen 1010. The display control unit 512 also displays a character string such as "Calling" in the status display area 1003, indicating that the administrator is being called. As another example, the display control unit 512 may display a character string such as "Calling" in the status display area 1003 after receiving control information from the notification management system 10.

In step S810, the event information transmission unit 513 of the first terminal device 101 transmits a call request including the template ID and information about the event selected in step S808 (hereinafter referred to as event information) to the notification management system 10.

In steps S811 and S812, when the reception unit 502 of the notification management system 10 receives a call request, the forwarding unit 503 obtains setting information corresponding to the template ID included in the call request from the setting information DB 15.

In step S813, the recording unit 505 of the notification management system 10 records log information related to the call request accepted by the acceptance unit 502 in the log information DB 14. At this time, various information such as identification information (hereinafter referred to as a notification ID) for identifying a series of processes (session) related to the accepted call request and the date and time of acceptance are added to the log information.

In step S814, the forwarding unit 503 of the notification management system 10 notifies the destination set in the acquired setting information of the event information, the notification ID, etc. For example, if the setting information acquired by the forwarding unit 503 includes a task item as shown in FIG. 7 (B), the forwarding unit 503 acquires the destination address from the list of forwarding destination 1 (user1, user2) stored in the task item ID "item2". Note that the list of forwarding destination 1 is an example of information of a first forwarding destination to which information of an event received from the first terminal device 101 is forwarded.

In step S815, when the event information receiving unit 522 of the second terminal device 102 receives the event information notified from the notification management system 10, the display control unit 523 displays, for example, a notification screen 1101 as shown in FIG. 11 (A) on the display 417, etc.

In the example of FIG. 11(A), the notification screen 1101 displays a call status display area 1102 that selectably displays one or more currently occurring events (calls), a response status display area 1103 that holds information on events being handled by other administrators, etc. The notification screen 1101 may also include a history button 1104 for viewing past call history. Note that in the notification screen 1101 shown in FIG. 11(A), "No. 3 Parts Out" displayed in the call status display area 1102 corresponds to the event information notified in step S814.

In step S816, when the administrator performs a response operation to select information on an event to which to respond from information on one or more events displayed in the call status display area 1102 of the notification screen 1101, the communication system 1 executes the processing from step S817 onward.

In step S817, when the operation acceptance unit 524 of the second terminal device 102 accepts a response operation by the administrator, the display control unit 523 displays, for example, a response screen 1111 as shown in Fig. 11 (B) on the display 417, etc. In the example of Fig. 11 (B), the response screen 1111 displays a call content display area 1112 for displaying information on the selected event (call), a response content input area 1113 for inputting the response content for the selected event, a transfer button 1114, and a completion button 1115, etc. Note that the format of the response content input field 1116 displayed in the response content input area 1113 can be customized by setting the setting information, and it is also possible to register, for example, photographed image data, recorded sound data, etc.

In step S818, the operation reception unit 524 of the second terminal device 102 sends a response including the notification ID of the event selected by the administrator's response operation to the notification management system 10.

In step S819, when the reception unit 502 of the notification management system 10 receives the response sent by the second terminal device 102, the recording unit 505 records log information related to the response received by the reception unit 502 in the log information DB 14. In addition, in step S820, the reception unit 502 transmits the received response to the first terminal device 101 that originated the request.

In step S821, when the communication unit 511 of the first terminal device 101 receives a response from the notification management system 10, the display control unit 512 displays, for example, a handling screen 1020 as shown in FIG. 10 (C) on the display 417, etc. For example, the display control unit 512 displays, for example, the character string "Handling" in the status display area 1003 of the handling screen 1020, indicating that the administrator is handling the situation.

As another example, the first terminal device 101 and the second terminal device 102 may use the call units 514 and 526 to transition to a call in progress state in which voice calls are possible, and the display control unit 512 may display a character string such as "Call in progress" in the status display area 1003. This allows the manager or the like to more appropriately determine the status (urgency, importance, etc.) of the site 30 by voice calls with the workers or the like, without having to rush to the site 30.

Following the above process, in step S822 of FIG. 9, the administrator responds to the event that occurred at the site 30 (e.g., rushes to the site 30, etc.).

In step S823, for example, when the administrator has finished responding to an event, the administrator performs an input operation to input the response details implemented by the administrator into the response details input field 1116 on the response screen 1111.

In step S824, the information transmission unit 525 of the second terminal device 102 transmits the response content entered by the administrator to the notification management system 10. This response content includes, for example, the notification ID included in the notification received in step S814.

In step S825, when the reception unit 502 of the notification management system 10 receives the response content sent by the second terminal device 102, the recording unit 505 records log information related to the response content received by the reception unit 502 in the log information DB 14. In addition, in step S826, the reception unit 502 transmits a completion notification to the first terminal device 101 indicating that the administrator's response has been completed.

In step 827, when the communication unit 511 of the first terminal device 101 receives the completion notification, the display control unit 512 displays again, for example, the operation screen 1001 as shown in FIG. 10 (A), and ends the series of processes corresponding to the notification ID.

By performing the above process, in the communication system 1 according to this embodiment, when a trouble (event) occurs at the site, the worker can notify one or more managers of the occurrence of the trouble simply by selecting a selection button displayed by the first terminal device 101.

In addition, the administrator can grasp an overview of one or more unaddressed troubles occurring at the site from the notification screen 1101 displayed by the second terminal device 102. Therefore, when multiple troubles occur at the site, it becomes easy for multiple administrators to split up and respond to the multiple troubles.

As described above, this embodiment enables managers and others to quickly respond to events that occur at production sites and other worksites.

Second Embodiment
In the second embodiment, for example, in Fig. 2, an example of processing will be described in which event information notified to the second terminal devices 102a and 102b held by the manager is transferred to the second terminal device 102c held by the replacement worker 213. Note that the second terminal device 102c may be, for example, a shared smartphone used by multiple replacement workers, and in this case, the manager or the like hands over the second terminal device 102c to the replacement worker in advance.

Figure 12 is a sequence diagram showing an example of a transfer process according to the second embodiment.

In step S1201, the second terminal device 102a is assumed to be displaying the corresponding screen 1111 as shown in FIG. 11 (B), for example, by the processing of steps S801 to S817 in FIG. 8.

In step S1202, the site manager 211 performs a transfer operation on the corresponding screen 1111. For example, the site manager 211 performs the transfer operation by selecting the transfer button 1114 displayed on the corresponding screen 1111.

In step S1203, the information sending unit 525 of the second terminal device 102a sends a transfer request including the notification ID and the event information to the notification management system 10.

In steps S1204 and S1205, when the reception unit 502 of the notification management system 10 receives a forwarding request, the forwarding unit 503 obtains setting information corresponding to the template ID included in the forwarding request from the setting information DB 15.

In step S1206, the forwarding unit 503 of the notification management system 10 forwards the event information, notification ID, etc. to the destination set in the acquired setting information. For example, if the setting information acquired by the forwarding unit 503 includes a task item as shown in FIG. 7 (B), the forwarding unit 503 acquires the destination address from the list of forwarding destinations 2 (user3) stored in the task item ID "item3". Note that the list of forwarding destinations 2 is an example of information on a second forwarding destination to which information on an event received from the second terminal device 102 is forwarded.

In step S1207, when the event information receiving unit 522 of the second terminal device 102c receives the transferred event information, the display control unit 523 displays, for example, a change instruction screen on the display 417, etc., which displays a change instruction from the site manager.

In step S1208, the replacement personnel can terminate the display of the replacement instruction screen by performing an acceptance operation on the replacement instruction screen to indicate that the instruction has been accepted, for example, when heading to the site 30 in accordance with the replacement instruction.

The above process is an example, and various modifications or applications are possible. For example, the transfer destination in response to the transfer request is not limited to the second terminal device 102c of the replacement worker 213, but may be the second terminal device 102b of the parts manager 212, etc.

[Third embodiment]
In the third embodiment, an example of processing is described in which an administrator or the like accesses the notification management system 10 using an information terminal 100 to perform management tasks such as viewing log information or setting configuration information.

(Log information display process)
13 is a sequence diagram showing an example of a process for displaying log information according to the third embodiment. This process shows an example of a process in which an administrator or the like uses a web browser 531 or the like of the information terminal 100 to display log information recorded in the log information DB 14. Note that the administrator may display the log information by using, not limited to, a web browser, but also an application for the communication system 1 having a function of a web browser.

In step S1301, the administrator performs a connection operation to connect to the user site 12 provided by the log information providing unit 506 of the notification management system 10, for example, using the web browser 531 of the information terminal 100. For example, the administrator performs an operation on the web browser 531, such as selecting a pre-set bookmark or inputting the URL of the user site 12.

In step S1302, the web browser 531 of the information terminal 100 executes a login process to log in to the user site 12. This login process may be performed by any method, but as an example, the web browser 531 of the information terminal 100 transmits a login request to the user site 12 using the administrator's user ID.

If the login request to the user site 12 contains valid authentication information issued by the authentication infrastructure 20, the authentication unit 504 of the notification management system 10 permits the login of the first terminal device 101. On the other hand, if the login request does not contain valid authentication information issued by the authentication infrastructure 20, the authentication unit 504 instructs the web browser 531 of the information terminal 100 to redirect to the authentication infrastructure 20. In this case, the web browser 531 performs authentication, for example, OAuth or OpenID, in the authentication infrastructure 20, and after obtaining valid authentication information, sends a login request to the user site 12, thereby enabling the user to log in to the user site 12.

In steps S1303 and S1304, the web browser 531 of the information terminal 100 acquires an operation screen (e.g., a web page) for viewing the log information from the log information providing unit 506 of the notification management system 10. In addition, in step S1305, the web browser 531 displays the acquired operation screen.

In step S1306, when the administrator performs an operation to display log information on the operation screen, the communication system 1 executes the processing from step S1307 onwards.

In step S1307, the web browser 531 of the information terminal 100 requests the log information providing unit 506 of the notification management system 10 to display the log information.

In steps S1308 and S1309, the log information providing unit 506 of the notification management system 10 acquires the log information recorded in the log information DB 14.

In steps S1310 and S1311, the log information providing unit 506 of the notification management system 10 creates a display screen for displaying the acquired log information, and transmits the created display screen for the log information to the information terminal 100. Preferably, the display screen for the log information includes a UI (User Interface) for sorting the log information, for example, by the date and time when an event occurred, the event that occurred, the type of notification, etc.

In step S1312, the web browser 531 of the information terminal 100 displays a display screen of the log information received from the log information providing unit 506 of the notification management system 10.

Figure 14 shows an example of log information according to the third embodiment. This figure shows an example of log information 1400 displayed on the log information display screen displayed by the web browser 531 in step S1312 of Figure 13.

In the example of FIG. 14, the log information 1400 includes information such as event, date and time, level, notification ID, notification type, and response content as items. The event is information on an event that occurred at the site 30. Specifically, it corresponds to a selection button such as "toilet", "out of parts", ... selected by the worker on the operation screen 1001 as shown in FIG. 10 (A). The date and time is information indicating, for example, the date and time when the notification management system 10 received the notification. The level is information indicating the level of the notification (for example, Warning, Alarm, etc.). The notification ID is identification information that identifies a series of notifications corresponding to a selection button such as "toilet", "out of parts", ... selected by the worker on the operation screen 1001 as shown in FIG. 10 (A).
The notification type is information indicating the type of notification, such as call, respond, close, cancel, etc. The action content is, for example, a character string indicating the action content input to a action screen 1111 as shown in FIG.

Event-related notifications relayed by the notification management system 10 are thus recorded in the log information DB 14, and the manager, etc. can view the log information using a web browser, etc., of the information terminal 100. In addition, the log information also records the response made by the manager, etc., so that the manager, etc. can easily evaluate and review the management system of the site 30 by analyzing the log information.

(Setting process of setting information)
15 is a sequence diagram showing an example of a setting process of setting information according to the third embodiment. This process shows an example of a process in which an administrator or the like sets the setting information stored in the setting information DB 15 using a web browser 531 or the like of the information terminal 100. Note that the administrator may set the setting information using a means other than a web browser, such as an application for the communication system 1 having a web browser function.

In step S1501, the administrator performs a connection operation to connect to the management site 11 provided by the setting information management unit 507 of the notification management system 10, for example, using the web browser 531 of the information terminal 100. For example, the administrator performs an operation on the web browser 531, such as selecting a bookmark that has been set in advance or inputting the URL of the management site 11.

In step S1502, the web browser 531 of the information terminal 100 executes a login process to log in to the management site 11. This login process may be similar to the login process described in step S1302 of FIG. 13.

In step S1503, the web browser 531 of the information terminal 100 requests the setting information management unit 507 of the notification management system 10 to obtain a setting screen for setting the setting information.

In steps S1504 and S1505, the setting information management unit 507 of the notification management system 10 acquires the setting information stored in the setting information DB 15.

In steps S1506 and S1507, the setting information management unit 507 of the notification management system 10 uses the acquired setting information to create a setting screen for the setting information and transmits it to the information terminal 100.

In step S1508, the web browser 531 of the information terminal 100 displays the setting screen received from the setting information management unit 507.

Fig. 16 is a diagram showing an image of a setting information setting screen according to the third embodiment. This diagram shows an example of a setting information setting screen 1600 displayed by the web browser 531 in step S1508 of Fig. 15. In the example of Fig. 16, the setting information setting screen 1600 displays a template name setting field 1601, a business name setting field 1602, an item name setting field 1603, and a setting button 1604, etc.

On this setting information setting screen 1600, the administrator can scroll the screen to display setting fields for each item of template 600, business information 601, and business items 602, as shown in Figs. 6(A) to (C), for example. After setting the setting information in each setting field, the administrator can perform setting operations by selecting the setting button 1604.

In step S1509, when the administrator performs a setting operation on the setting screen 1600, the communication system 1 executes the processing from step S1510 onwards.

In step S1510, the web browser 531 of the information terminal 100 transmits the settings configured on the setting screen 1600 to the setting information management unit 507 of the notification management system 10.

In steps S1511 and S1512, the setting information management unit 507 of the notification management system 10 updates the setting information by reflecting the setting contents received from the web browser 531 in the setting information stored in the setting information DB 15.

By the above process, the administrator can easily set the setting information as shown in, for example, FIGS. 6 (A) to 6(C) using the web browser 531 of the information terminal 100 or the like.

As described above, each embodiment of the present invention enables managers and others to quickly respond to events that occur at production sites and other worksites.
