  Hereinafter, an information transmission / reception system, a terminal device, an information processing method, and a program according to embodiments will be described with reference to the drawings.

(First embodiment)
FIG. 1 shows an example of a monitoring system to which the information transmission / reception system in this embodiment is applied.
The monitoring system shown in the figure includes a monitoring server 100, a plurality of monitoring terminals 200 (an example of a terminal device), and one or more monitoring target devices 300.
The monitoring server 100 is communicably connected to each of the monitoring target devices 300, and monitors the state of each of the monitoring target devices 300. Note that communication between the monitoring server 100 and the monitoring target device 300 may be wired or wireless.
Moreover, the monitoring target apparatus 300 in this embodiment can mention the circuit breaker in an electric power system, etc. as an example. However, the type of device as the monitoring target device 300 is not particularly limited.

  In addition, the monitoring server 100 is connected to each of the monitoring terminals 200 so as to be communicable. The monitoring server 100 can transmit device status information obtained by monitoring the monitoring target device 300 to the monitoring terminal 200. The device status information is information indicating the status of the monitoring target device 300.

The monitoring terminal 200 is a terminal used by each monitoring person who is a user of the monitoring system to manage the monitoring target device.
The monitoring terminal 200 can display a user interface screen in which the status of the monitoring target device 300 is reflected using the device status information received from the monitoring server 100. The user interface screen is a screen that can be operated by the user (monitoring person).

In addition, the monitoring terminal 200 executes a predetermined process in response to an operation on the user interface screen.
As an example, the monitoring terminal 200 transmits a command to the monitoring server 100 in response to an operation performed on a user interface screen for controlling a monitoring target device. The monitoring server 100 controls the monitoring target device 300 to be controlled according to the received command. Thereby, the monitoring target device 300 operates in accordance with an operation performed by the monitor on the user interface screen of the monitoring terminal 200.

  Further, in this embodiment, the user interface screen is shared so that the user interface screen in the same state as the user interface screen displayed on one monitoring terminal 200 is also displayed on the other monitoring terminals 200. . Hereinafter, sharing of the user interface screen in the present embodiment will be described.

FIG. 2 shows an example of a user interface screen displayed on one monitoring terminal 200.
The user interface screen shown in the figure includes a fixed area FXA and a main window MWD. The fixed area FXA is an area that is always fixed and displayed. However, the display of buttons, messages, and the like in the fixed area FXA changes as appropriate according to, for example, the operation of the monitor or the processing result of the monitoring terminal 200.

In the main window MWD, for example, information corresponding to the function designated by the operation of the supervisor is displayed. As an example, a system diagram K and a sub-window SWD are displayed in the main window MWD of FIG.
The system diagram K shows the monitoring target device 300 together with the connection system. Further, the icon indicating the monitoring target device 300 in the system diagram K indicates the state of the corresponding monitoring target device 300, for example, by a predetermined display mode.
The sub window SWD is a window displayed in the main window MWD. The sub-window SWD in the figure is a device control window that indicates the status of the monitoring target device 300 selected from the monitoring target devices 300 indicated as icons in the system diagram K, for example, and can be controlled on and off.

In the sub-window SWD shown in the figure, a text TX, an on button BT1, and an off button BT2 are arranged.
The text TX represents the state of the corresponding monitoring target device 300 as a text message. In the text TX of the figure, for example, a message “device state normal” indicates that the corresponding monitored device 300 is currently operating normally.
The on button BT1 is a button for performing an operation of switching the operation of the corresponding monitoring target device 300 from off to on. The off button BT2 is a button for performing an operation of switching the operation of the corresponding monitoring target device 300 from on to off.
In the case of the figure, according to the corresponding monitoring target device 300 being in the on state, the on button BT1 is displayed as being inoperable by displaying, for example, gray out. On the other hand, the off button BT2 is normally displayed, indicating that it can be operated.

Here, a monitor (sending monitor) who uses the monitoring terminal 200 on which the user interface screen of FIG. 2 is displayed wanted to display the user interface screen of FIG. 2 on other monitoring terminals 200 as well. If so, do the following:
First, the transmission side supervisor operates the transmission button BT3 arranged in the fixed area FXA. The send button BT3 is a button for performing an operation for giving an instruction to transmit the user interface screen displayed when the operation is performed to another monitoring terminal 200.
The transmission of the user interface screen here means transmission of screen construction information including information for reproducing the user interface screen.

In response to the operation of the transmission button BT3, the screen transmission dialog shown in FIG. 3 is displayed on the user interface screen of FIG.
In the screen transmission dialog shown in the figure, an input box BX1, a transmission confirmation button BT11, and a cancel button BT12 are arranged.
The transmission side supervisor inputs the terminal ID of the monitoring terminal 200 that is the transmission destination of the user interface screen in the input box BX1 in the screen transmission dialog. That is, in this case, designation of the monitoring terminal 200 as the transmission destination on the user interface screen is performed by inputting the terminal ID in the input box BX1.

The transmission side supervisor operates the transmission confirmation button BT11 after inputting the terminal ID in the input box BX1. In response to the operation of the transmission confirmation button BT11, the monitoring terminal 200 transmits screen construction information for reproducing the main window MWD as the user interface screen shown in FIG. 2 to the monitoring terminal 200 designated as the transmission destination.
Thus, in this embodiment, a user interface screen is transmitted by transmitting screen construction information. Hereinafter, transmission of screen construction information is synonymous with transmission of a user interface screen.

Note that the transmission-side supervisor may operate the cancel button BT12 when it is desired to stop transmission of the user interface screen under the state where the screen transmission dialog shown in FIG.
In response to the operation of the cancel button BT12, the screen transmission dialog is hidden, and the display returns to the display state shown in FIG. 2, for example.

FIG. 4 is an example of screen construction information transmitted by the monitoring terminal 200. The screen construction information in the figure corresponds to the state of the main window MWD in FIG.
In the screen construction information shown in the figure, the <mainwindow> and </ mainwindow> tags define the state of the main window MWD.
The description of <windowtype> w0001 </ windowtype> indicates the type (type) of the main window MWD. In the same figure, “w0001” specified by the tag <windowtype> w0001 </ windowtype> is the monitoring screen of the monitoring target device 300 in which the type of the main window MWD in FIG. Is an identifier.
The description <x> 300 </ x> indicates the horizontal size of the main window MWD.
The description <y> 400 </ y> indicates the vertical size of the main window MWD.
The description of <pos> (0,10) </ pos> indicates, for example, the coordinates where the upper left vertex of the main window MWD is located as the position of the main window MWD.
The description of <scroll> 0 </ scroll> indicates a scroll state in the main window MWD.

<subwindow> and <subwindow> tags define subwindows arranged in the main window MWD.
Under the <subwindow> and </ subwindow> tag hierarchy, the description of <type> control </ type> specifies that the type of the subwindow SWD is a device control window.
In addition, the description of <text> device state normal </ text> specifies that the content in the sub-window SWD as the device control window is “device state normal”.
Further, the description of <btn1> btnON </ btn1> specifies that the on button BT1 is arranged in the sub-window SWD. Further, the description of <state> disable </ state> under the tag hierarchy of <btn1> and </ btn1> specifies that the on button BT1 should be inactive.
Further, the description of <btn2> btnOFF </ btn2> specifies that the off button BT2 is arranged in the sub-window SWD. Further, the description of <state> able </ state> under the tag hierarchy of <btn2> and </ btn2> specifies that the off button BT2 should be active.
Thus, the contents described in the screen construction information include information for reproducing the user interface screen.

The monitoring terminal 200 that has received the screen construction information displays a display confirmation dialog shown in FIG. 5, for example. As shown in the figure, a message is displayed in the display confirmation dialog, for example, “Do you want to allow reception of the screen from the supervisor A?”. In the display confirmation dialog, a permission button BT21 and a rejection button BT22 are arranged.
The reception-side supervisor can immediately know that the user interface screen has been transmitted by displaying the display confirmation dialog. In addition, the receiving side monitor can recognize that the monitor who has transmitted the user interface screen is the monitor A by viewing the above message.

  When the reception side monitor can permit the reception of the user interface screen transmitted from the monitor A, he operates the permission button BT21. On the other hand, for example, when it is not a situation where the user interface screen of the monitor A can be confirmed now, the receiver monitor can reject the display of the user interface screen transmitted from the monitor A. In this case, the reception side supervisor operates the rejection button BT22.

When the permission button BT21 is operated, the monitoring terminal 200 of the receiving side monitor reproduces the main window MWD using the received screen construction information.
Specifically, the monitoring terminal 200 of the receiving side supervisor recognizes that the user interface screen as the main window MWD should be constructed by the <mainwindow> tag in the screen construction information of FIG. Furthermore, the monitoring terminal 200 of the reception side supervisor refers to <windowtype> w0001 </ windowtype> in the screen construction information and recognizes that the main window MWD is the type indicated by the identifier “w0001”.
The monitoring terminal 200 of the receiving side monitor stores data of various objects such as windows, buttons, and system diagrams arranged on the user interface screen. Therefore, the monitoring terminal 200 reads an object corresponding to the main window MWD of the type indicated by the identifier “w0001”.
Then, the monitoring terminal 200 of the receiving side supervisor uses the read object to create a main window MWD having a size according to the description of <x> 300 </ x> and the description of <y> 400 </ y>. Generate. The monitoring terminal 200 of the reception side supervisor expands the generated main window MWD at a position on the screen indicated by <pos> (0,10) </ pos>.
In addition, the monitoring terminal 200 of the reception side supervisor sets the scroll state in the main window MWD according to the description of <scroll> 0 </ scroll>.

Further, the monitoring terminal 200 of the reception side supervisor recognizes that the subwindow is arranged in the main window MWD depending on the tag of <subwindow>, and reads the object of the subwindow.
Further, the monitoring terminal 200 of the receiving side supervisor recognizes that the type of the subwindow is a screen transmission dialog according to the description of <type> control </ type>. The monitoring terminal 200 of the reception side supervisor arranges the characters “device state normal” at the position of the text TX in the screen transmission dialog according to the description of <text> device state normal </ text>.
Further, the monitoring terminal 200 of the receiving side supervisor reads the object of the on button BT1 according to the description of <btn1> btnON </ btn1>, and arranges the on button BT1 in the screen transmission dialog. In addition, the monitoring terminal 200 of the receiving-side supervisor sets the on button BT1 in a grayed-out state according to the description of <state> disable </ state> below the <btn1>, </ btn1> hierarchy so that no operation is accepted. Set to.

Further, the monitoring terminal 200 of the reception side supervisor reads the object of the off button BT2 according to the description of <btn2> btnOFF </ btn2>, and arranges the on button BT1 in the screen transmission dialog. In addition, the monitoring terminal 200 of the receiving side supervisor can accept the operation by arranging the off button BT2 in the active state according to the description of <state> able </ state> in the hierarchy of <btn1> and </ btn1>. Set as follows. As a result of the processing being performed in this manner, the main window MWD is reproduced based on the screen construction information.
Then, the monitoring terminal 200 of the receiving side monitor displays the main window MWD reproduced as described above.

As described above, the main window MWD displayed on the monitoring terminal 200 of the receiving side supervisor reproduces the same state as that shown in FIG. In this way, in this embodiment, the user interface screen displayed on the monitoring terminal 200 of the transmission side supervisor is shared with the monitoring terminal 200 of the reception side supervisor.
Further, the main window MWD displayed on the monitoring terminal 200 of the receiving side monitor is not based on the image data of the main window MWD, but is constructed using an object stored in the monitoring terminal 200 of the receiving side monitor. Yes.
Accordingly, the reception side supervisor can perform an operation on the user interface screen including the displayed main window MWD.

As an example, sharing of a user interface screen in the present embodiment is utilized as follows.
For example, when the monitor A is not yet skilled, there are cases where the operation of the monitoring target device 300 that he / she is in charge of cannot be sure. In such a case, the supervisor A wants to have another supervisor B who is more skilled than himself / herself confirm the operation on his / her monitoring target device 300.
Therefore, in this case, the supervisor A causes the monitoring terminal 200 to display the main window MWD in which the result of the operation of the monitoring target device 300 is reflected. In addition, as described above, the monitoring person A designates the monitoring terminal 200 of the monitoring person B as a transmission destination and transmits a user interface screen (screen construction information).

The user interface screen (screen construction information) transmitted as described above is received by the monitoring terminal 200 of the monitoring person B. In response to the reception of the user interface screen, the monitoring terminal 200 of the monitoring person B displays the display confirmation dialog illustrated in FIG.
For example, as described with reference to FIG. 5, the supervisor B operates the permission button BT21 arranged in the display confirmation dialog displayed on the monitoring terminal 200 operated by the supervisor B. Accordingly, the main window MWD in the same state as that displayed on the monitoring terminal 200 of the monitoring person A is displayed on the monitoring terminal 200 of the monitoring person B.
Note that the operation confirmation request from the supervisor A to the supervisor B may be made verbally or by telephone.

The monitor B can check whether the operation of the monitor A is appropriate by looking at the displayed main window MWD. In addition, if the operation of the supervisor A is not appropriate, the operation can be immediately corrected by operating the user interface screen including the displayed main window MWD as it is.
In this way, since the user interface screen can be shared in the present embodiment, it is possible to facilitate management work of the monitoring target device 300 in a monitoring system, for example.

Also, for example, when the other side is busy with other tasks and there is no room for checking the user interface screen of the sending side monitor, the receiving side monitor may operate the reject button BT22 in the display confirmation dialog shown in FIG. .
In response to the operation of the refusal button BT22, the monitoring terminal 200 of the reception side supervisor transmits a display refusal notification to the monitoring terminal 200 of the transmission side supervisor.
In response to receiving the display refusal notification, the monitoring terminal 200 of the sending side monitor displays a screen display refusal notification dialog.

FIG. 6 shows an example of a screen display rejection notification dialog. In the screen display refusal notification dialog shown in the figure, a message such as “Monitor B refuses to display the screen” is displayed. By looking at such a message, the transmission side supervisor can know that the display of the user interface screen transmitted by the reception side supervisor is rejected by the reception side supervisor.
The sending side supervisor who knows that the display of the user interface screen is rejected operates the OK button BT31 in the screen display rejection notification dialog as an operation for confirmation. By operating the OK button BT31, the screen display rejection notification dialog is deleted.

Here, transmission / reception of screen construction information, display rejection notification, and the like between the monitoring terminals 200 is performed via the monitoring server 100. Through the monitoring server 100, for example, authentication processing for the monitoring terminal 200 can be performed in the monitoring server 100 in an integrated manner.
Note that, without passing through the monitoring server 100, transmission and reception of screen construction information, display rejection notification, and the like may be performed between the monitoring terminals 200.

In the present embodiment, an access right is set for each monitor of the monitoring terminal 200. In the case of this embodiment, the user interface screen that can be displayed on the monitoring terminal 200 differs depending on the access right.
For this reason, for example, the access right set according to the monitor in the monitoring terminal 200 designated as the transmission destination of the user interface screen by the transmission side monitor may not be able to access the user interface screen to be transmitted.
In such a case, even if the transmission side supervisor transmits the user interface screen, the user interface screen is not displayed on the transmission destination monitoring terminal 200. Further, on the monitoring terminal 200 of the transmission side supervisor, a screen transmission impossible notification dialog as shown in FIG. 7 is displayed.

  In the screen transmission disabling notification dialog in the figure, for example, a message “Cannot be transmitted to a user without access right” is displayed. By looking at this message, the transmission side supervisor can recognize that transmission is not possible because the supervisor of the transmission destination monitoring terminal 200 does not have access rights to the user interface screen to be transmitted. Therefore, the transmission side supervisor operates the OK button BT41 for confirmation. In response to the operation of the OK button BT41, the screen transmission impossible notification dialog is deleted.

As a modification of the present embodiment, a screen transmission dialog as illustrated in FIG. 8 may be displayed instead of the screen transmission dialog in FIG.
In the screen transmission dialog shown in the figure, a monitor of another monitoring terminal 200 is presented. The figure is an example of a screen transmission dialog displayed on the monitoring terminal 200 of the monitoring person A, and a monitoring person B, a monitoring person C, a monitoring person D, and a monitoring person E are presented. A radio button RBT is arranged for each of the presented monitor B, monitor C, monitor D, and monitor E.
In this case, the monitor A operates the radio button RBT corresponding to the monitor who wants to transmit the user interface screen among the monitor B, the monitor C, the monitor D, and the monitor E to make the selected state. In this case, the selection of the radio button RBT is not alternative and multiple selections are possible. Accordingly, a plurality of user interface screen transmission destinations can be selected under the screen transmission dialog shown in FIG. In the example of the figure, a state where the monitor B and the monitor D are selected is shown.

Then, the supervisor A operates the radio button RBT as described above to select the transmission destination of the user interface screen, and then operates the transmission confirmation button BT11. In response to the operation of the transmission confirmation button BT11, the monitoring terminal 200 transmits user interface screens to the two monitoring terminals 200 corresponding to the monitor B and the monitor D, respectively.
Also in this case, if the transmission on the user interface screen is to be stopped, the transmission side supervisor may operate the cancel button BT12.

Next, a configuration example of the monitoring terminal 200 will be described with reference to FIG. The monitoring terminal 200 shown in the figure includes a communication unit 201, a control unit 202, a storage unit 203, a display unit 204, and an operation unit 205.
The communication unit 201 communicates with the monitoring server 100.

The control unit 202 executes various controls for realizing the function as the monitoring terminal 200. The function as the control unit 202 is realized by, for example, a CPU (Central Processing Unit) included in the monitoring terminal 200 executing a program.
The control unit 202 includes a screen display control unit 221 (an example of a transmission-side screen display control unit and a reception-side screen display control unit), a screen construction information transmission control unit 222, and a screen construction information reception processing unit 223.
The screen display control unit 221 (transmission-side screen display control unit) causes the display unit 204 to display a user interface screen.
Further, the screen display control unit 221 (reception-side screen display control unit) reproduces using the screen construction information received from the transmission-side monitoring terminal 200 when the monitoring terminal 200 is the reception side of the user interface screen. A user interface screen is displayed on the display unit 204.
Hereinafter, a user interface screen displayed using the screen construction information received from the monitoring terminal 200 on the transmission side is also referred to as a “reception user interface screen”.

  The screen construction information transmission control unit 222 transmits screen construction information including information for reproducing the user interface screen in the same state as the user interface screen displayed by the screen display control unit 221 to another monitoring terminal (receiving device). .

The screen construction information reception processing unit 223 executes processing according to reception of the user interface screen (screen construction information) when the monitoring terminal 200 is the reception side of the user interface screen.
As processing according to reception of the user interface screen, the screen construction information reception processing unit 223 displays a display permission instruction operation screen in response to reception of screen construction information. The display enable / disable instruction operation screen is a screen that allows an operation to instruct whether to display the reception user interface screen, and an example thereof is the display confirmation dialog illustrated in FIG. 5.

  The storage unit 203 stores various information used by the control unit 202. For example, the storage unit 203 stores programs executed by the CPU corresponding to the control unit 202, various objects on the user interface screen, and the like.

The display unit 204 displays an image according to the control of the control unit 202.
The operation unit 205 collectively indicates operators and operation devices included in the monitoring terminal 200. The operation unit 205 includes input devices such as a keyboard, a mouse, and a touch pad. An operator or an operation device as the operation unit 205 outputs an operation signal to the control unit 202 in response to an operation. The control unit 202 executes control according to the input operation signal.

  Next, an example of a processing procedure executed by the monitoring terminal 200 on the transmission side and the monitoring terminal 200 on the reception side of the user interface screen will be described with reference to the flowchart of FIG. In the present embodiment, as described above, transmission / reception of information between the monitoring terminals 200 is performed via the monitoring server 100. However, in the same figure, the monitoring server 100 is omitted for convenience of explanation.

First, the processing procedure executed by the monitoring terminal 200 of the transmitting side supervisor will be described. The processing of the monitoring terminal 200 of the transmission side supervisor in the figure is started under the state where the user interface screen as illustrated in FIG. 2 is displayed.
The screen construction information transmission control unit 222 waits for a screen transmission instruction operation to instruct transmission of the currently displayed user interface screen (step S101—NO). The screen transmission instruction operation here is an operation for the transmission button BT3 in the fixed area FXA of the user interface screen in FIG. 2, and the subsequent operation for the screen transmission dialog shown in FIG. 3 or FIG.

In response to the screen transmission instruction operation (step S101—YES), the screen construction information transmission control unit 222 confirms the access right of the monitor corresponding to the monitoring terminal 200 designated as the transmission destination (step S102). ).
Next, the screen construction information transmission control unit 222 determines whether or not it is possible to access the user interface screen to be transmitted this time with the access right confirmed in step S102 (step S103).

If accessible (step S103—YES), the screen construction information transmission control unit 222 generates screen construction information for reproducing the user interface screen (main window MWD) currently displayed on the display unit 204. (Step S104).
Then, the screen construction information transmission control unit 222 transmits the screen construction information generated in step S104 to the monitoring terminal 200 designated as the transmission destination in the screen transmission instruction operation performed corresponding to step S101 (step S101). S105).

After transmitting the screen construction information in step S105, the screen display control unit 221 determines whether a display rejection notification from the monitoring terminal 200 on the receiving side has been received (step S106). The display rejection notification is transmitted when the monitoring terminal 200 on the receiving side rejects reception of the screen construction information transmitted in step S105.
When a display rejection notification has not been received (step S106—NO). The screen construction information transmitted in step S105 is displayed without being rejected in the monitoring terminal 200 on the receiving side. Therefore, in this case, the processing shown in FIG. When the display rejection notification is not received, a dialog for notifying that the display of the user interface screen is accepted may be displayed on the monitoring terminal 200 on the receiving side.

  On the other hand, when the display rejection notification is received, the screen display control unit 221 displays the screen display rejection notification dialog illustrated in FIG. 6 (step S107).

In addition, when it is determined that the user interface screen cannot be accessed with the access right corresponding to the monitor of the transmission destination monitoring terminal 200 (step S103—NO), the following processing is executed.
That is, the screen display control unit 221 displays the screen transmission impossibility notification dialog illustrated in FIG. 7 (step S108).

  As the control according to the access right, for example, the monitoring terminal 200 on the receiving side may determine whether or not there is an access right for the received user interface screen reproduced by the received screen construction information. In this case, if there is no access right, the reception-side terminal device 200 may notify the transmission-side monitoring terminal 200 that the reception of the screen construction information has been rejected because there is no access right.

Next, a processing procedure executed by the monitoring terminal 200 on the receiving side will be described. In the monitoring terminal 200 on the reception side, the communication unit 201 receives the screen construction information transmitted from the monitoring terminal 200 on the transmission side in step S105 (step S201).
In response to the reception of the screen construction information in step S201, the screen construction information reception processing unit 223 displays the display confirmation dialog illustrated in FIG. 5 (step S202).

  Under the state in which the display confirmation dialog is displayed in step S202, the screen construction information reception processing unit 223 determines whether a display permission operation has been performed (step S203). The display permission operation is an operation on the permission button BT21 in the display confirmation dialog shown in FIG.

  When a display permission operation is performed (step S203—YES), the screen display control unit 221 reproduces the user interface screen as described above using the screen construction information received in step S201. The user interface screen reproduced in this way is the reception user interface screen. The screen display control unit 221 displays the reception user interface screen (step S204).

On the other hand, when the reject button BT22 in the display confirmation dialog is operated, the display permission operation is not performed (step S203—NO). In this case, the screen construction information reception processing unit 223 transmits a display rejection notification to the monitoring terminal 200 on the transmission side (step S205). In this case, since step S204 is skipped, the reception user interface screen based on the screen construction information received in step S201 is not displayed.
By such processing, the user interface screen displayed on one monitoring terminal 200 is shared so that it can be displayed on other monitoring terminals 200 in an operable manner.

In the process of the transmission-side monitoring terminal 200 shown in the figure, the screen construction information is not transmitted as a mode of restricting the transmission of the screen construction information according to the access right of the transmission destination monitoring terminal 200. I am doing so.
However, as an aspect of restricting the transmission of screen construction information, for example, screen construction information that can be reproduced in part according to the access right on the user interface screen displayed on the monitoring terminal 200 on the transmission side is transmitted. Also good. Moreover, you may make it transmit the screen construction information with which the item which can be operated according to the access right was restrict | limited as an aspect of a transmission restriction | limiting of screen construction information.

(Second Embodiment)
Next, the second embodiment will be described. The monitoring server 100 according to the present embodiment detects whether or not a failure has occurred as a monitoring operation for the monitoring target device 300. When a failure occurs in the monitoring target device 300, the monitoring server 100 transmits an alarm (warning) to each monitoring terminal 200. For example, the alarm in this embodiment may simply notify that any of the monitoring target devices 300 has failed. Or the alarm in this embodiment may notify the occurrence of a failure including information indicating the monitored device 300 in which the failure has occurred, information indicating the content of the failure, and the like.

  As a basic operation of the monitoring terminal 200 that has received the alarm, a display for notifying the monitoring target device 300 that a failure has occurred is performed on the display unit 204 at a timing according to the reception of the alarm. Specifically, an alarm window including a message indicating that a failure has occurred in the monitoring target device 300 is displayed in a pop-up manner.

  However, the monitoring target device 300 notified by the alarm is not necessarily severe. Some supervisors do not need to respond to alarms depending on the given work contents. For this reason, some supervisors may want to prioritize confirmation of user interface screens transmitted from other supervisors over alarms. In this case, it becomes troublesome for the monitor to display the alarm window while checking the displayed user interface screen.

Therefore, in the present embodiment, when the display-side monitor performs display confirmation using the display confirmation dialog, the permission in the normal mode and the permission in the alarm restriction mode are selected to permit the display of the user interface screen. It can be so.
Therefore, in the monitoring terminal 200 on the receiving side in the present embodiment, a display confirmation dialog shown in FIG. 11 is displayed instead of the display confirmation dialog in FIG. 5 in response to reception of the user interface screen.

In the display confirmation dialog shown in the figure, two permission buttons, a normal mode support permission button BT21a and an alarm restriction mode support permission button BT21b, are arranged.
Here, the normal mode is a mode in which when an alarm is received, an alarm window is displayed regardless of what user interface screen is displayed.
The alarm restriction mode is a mode for restricting alarm notification when an alarm is received. Specifically, the alarm restriction mode displays an alarm window when an alarm is received and the reception user interface screen is not displayed. However, in this mode, the alarm window is not displayed when the reception user interface screen is displayed.

Even when the reception side user interface screen is displayed, the reception side supervisor operates the normal mode support permission button BT21a when an alarm window is to be displayed when an alarm is received.
In response to operation of the normal mode support permission button BT21a, the monitoring terminal 200 on the reception side displays a reception user interface screen under the normal mode.

On the other hand, when it is desired to display the reception user interface screen without displaying the alarm window even when an alarm is received, the reception side supervisor operates the alarm restriction mode support permission button BT21b.
In response to the operation of the alarm restriction mode support permission button BT21b, the monitoring terminal 200 on the reception side displays the reception user interface screen under the alarm restriction mode.

FIG. 12 shows a configuration example of the monitoring terminal 200 in this embodiment. In the figure, the same parts as those in FIG.
In the monitoring terminal 200 shown in the figure, the control unit 202 further includes an alarm response control unit 224.
When the alarm response control unit 224 is displaying the reception user interface screen and an alarm is transmitted from the monitoring server 100, if alarm notification is permitted, the alarm response control unit 224 displays the alarm notification. On the other hand, when an alarm is transmitted from the monitoring server 100 when the reception user interface screen is displayed, the alarm response control unit 224 restricts alarm notification when alarm notification is not permitted. . Specifically, in the present embodiment, alarm notification is limited so that alarm notification is not performed on the reception user interface screen when alarm notification is not permitted.

  The flowchart in FIG. 13 illustrates an example of a processing procedure executed by the reception-side monitoring terminal 200 according to the present embodiment in response to reception of screen construction information. In the figure, the same steps as those executed by the monitoring terminal 200 on the receiving side in FIG.

  In response to the screen construction information being received by the communication unit 201 in step S201, the screen construction information reception processing unit 223 displays a display confirmation dialog in step S202. Here, depending on step S202 of this embodiment, the display confirmation dialog illustrated in FIG. 11 is displayed.

After displaying the display confirmation dialog, the screen construction information reception processing unit 223 determines whether or not the “permit in normal mode” operation has been performed as an operation on the display confirmation dialog (step S203A). The “permit in normal mode” operation is an operation on the normal mode support permission button BT21a.
When the “permit in normal mode” operation is performed (step S203A—YES), the screen construction information reception processing unit 223 sets the normal mode (step S211). In step S204, the screen display control unit 221 displays the reception user interface screen using the screen construction information received in step S201.

  When the “permit in normal mode” operation is not performed (step S203A-NO), the screen construction information reception processing unit 223 further determines whether or not the “permit in alarm limit mode” operation is performed ( Step S203B). The “permit in alarm limit mode” operation is an operation on the alarm limit mode permission button BT21b.

When the “permit in alarm limit mode” operation is performed (step S203B—YES), the screen construction information reception processing unit 223 sets the alarm limit mode (step S212). In step S204, the screen display control unit 221 displays the reception user interface screen using the screen construction information received in step S201.
In response to the alarm restriction mode being set in step S212, for example, the screen display control unit 221 displays a message indicating that the alarm restriction mode has been set on the screen including the reception user interface screen. You may be made to be. As an example, the display mode of the transmission button BT3 in the fixed area FXA may be changed so as to indicate that the alarm restriction mode is set.

  If the “permit in alarm limit mode” operation is not performed (step S203B-NO), the reject button BT22 in the display confirmation dialog is operated. Therefore, the screen construction information reception processing unit 223 in this case transmits a display rejection notification to the monitoring terminal 200 on the transmission side (step S205). In this case, the reception user interface screen is not displayed in step S204.

Next, a processing procedure example executed by the receiving monitoring terminal 200 in response to receiving an alarm from the monitoring server 100 will be described with reference to a flowchart of FIG.
In the monitoring terminal 200 on the receiving side, the alarm handling control unit 224 waits for an alarm transmitted from the monitoring server 100 to be received (step S301—NO).

When an alarm is received (step S301—YES), the alarm handling control unit 224 determines whether or not the reception user interface screen is currently being displayed (step S302).
When the reception user interface screen is being displayed (step S302—YES), the alarm response control unit 224 further determines whether or not the normal mode is currently set (step S303).

  When the normal mode is set (step S303—YES), the alarm response control unit 224 displays an alarm window corresponding to the alarm received in step S301. As described above, the process proceeds from step S303 to step S304, whereby an alarm window is displayed on the reception user interface screen in the normal mode.

  On the other hand, when the normal mode is not set (step S303-NO), the alarm restriction mode is set. Therefore, the alarm response control unit 224 in this case skips step S304 and ends the process shown in FIG. In this way, when the reception user interface screen is displayed under the alarm restriction mode, the alarm window corresponding to the alarm received in step S301 can be prevented from being displayed.

  Even when the reception user interface screen is not being displayed in step S302, an alarm window is displayed in step S304.

(Third embodiment)
Subsequently, a third embodiment will be described. In the present embodiment, a level (alarm level) at a predetermined level is set in the alarm transmitted by the monitoring server 100 according to, for example, the severity of a failure that has occurred.
In the case of the second embodiment, in the alarm restriction mode, the alarm window corresponding to the received alarm is not uniformly displayed regardless of the alarm level.
However, the receiving side supervisor may not be notified of an alarm with a low alarm level, but may desire to receive notification of an alarm with a certain alarm level or higher.

  Therefore, in the present embodiment, when the alarm restriction mode is set and the user interface screen is displayed, the display control of the alarm window is performed as follows according to the alarm level corresponding to the received alarm. Configure as follows. In other words, the monitoring terminal 200 on the receiving side according to the present embodiment is configured not to display an alarm window when the alarm level is lower than a certain level, and to display an alarm window when the alarm level is equal to or higher than a certain level.

The configuration of the monitoring terminal 200 in this embodiment may be the same as that in FIG. In addition, in the case where alarm notification is not permitted, the alarm response control unit 224 in the present embodiment performs display for notifying the alarm when the level of the received alarm is equal to or higher than a certain level.
On the other hand, when alarm notification is not permitted, the alarm response control unit 224 limits the alarm notification so that the alarm notification display is not performed when the alarm level is less than a certain level.

  The flowchart in FIG. 15 illustrates an example of a processing procedure that the monitoring terminal 200 on the receiving side according to the present embodiment executes in response to receiving an alarm from the monitoring server 100. In the figure, the same steps as those in FIG. 14 are denoted by the same reference numerals, and the description thereof is omitted.

When it is determined in step S303 that the alarm handling control unit 224 is not in the normal mode (that is, the alarm restriction mode), the following process is performed.
That is, the alarm response control unit 224 recognizes the alarm level indicated by the alarm received in step S301 (step S311).
Next, the alarm response control unit 224 determines whether the alarm level recognized in step S311 is equal to or higher than a certain level (step S312).

  If the alarm level is equal to or higher than a certain level (step S312—YES), the alarm handling control unit 224 displays an alarm window on the currently displayed reception user interface screen in step S304.

  On the other hand, if the alarm level is less than a certain level (step S312—NO), the alarm handling control unit 224 skips step S304 and ends the process shown in FIG. As a result, the alarm window is not displayed on the receiving user interface screen currently being displayed.

By executing the processing shown in FIG. 15 as described above, if the alarm level of the received alarm is higher than a certain level when the reception user interface screen is displayed in the alarm restriction mode, it is determined that the alarm has occurred. The supervisor can be notified.
In the present embodiment, the threshold of the alarm level determined in step S312 may be arbitrarily set according to the convenience of the monitor by the operation of the monitor.

  Note that, in each of the above embodiments, a case where the user interface screen is shared between the monitoring terminals 200 in the monitoring system is taken as an example. However, the configuration for sharing the user interface screen according to the present embodiment can be applied to an information processing system other than the monitoring system.

  According to at least one embodiment described above, the transmission-side monitoring terminal 200 transmits screen construction information that reproduces the user interface screen displayed on the display unit, and the reception-side monitoring terminal 200 constructs the screen. A state in which a user interface screen reproduced using information is displayed, so that the same user interface screen image displayed on one terminal device can be operated on another terminal device. Can be displayed.

  It should be noted that a program for realizing the function as the monitoring terminal 200 is recorded on a computer-readable recording medium, and the program recorded on the recording medium is read into a computer system and executed, thereby executing the monitoring. Each process as the terminal 200 may be performed. Here, “loading and executing a program recorded on a recording medium into a computer system” includes installing the program in the computer system. The “computer system” here includes an OS and hardware such as peripheral devices. Further, the “computer system” may include a plurality of computer devices connected via a network including a communication line such as the Internet, WAN, LAN, and dedicated line. The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. As described above, the recording medium storing the program may be a non-transitory recording medium such as a CD-ROM. The recording medium also includes a recording medium provided inside or outside that is accessible from the distribution server in order to distribute the program. The code of the program stored in the recording medium of the distribution server may be different from the code of the program that can be executed by the terminal device. That is, the format stored in the distribution server is not limited as long as it can be downloaded from the distribution server and installed in a form that can be executed by the terminal device. Note that the program may be divided into a plurality of parts, downloaded at different timings, and combined in the terminal device, or the distribution server that distributes each of the divided programs may be different. Furthermore, the “computer-readable recording medium” holds a program for a certain period of time, such as a volatile memory (RAM) inside a computer system that becomes a server or a client when the program is transmitted via a network. Including things. The program may be for realizing a part of the functions described above. Furthermore, what can implement | achieve the function mentioned above in combination with the program already recorded on the computer system, what is called a difference file (difference program) may be sufficient.
