The operation PC 20 causes the video output from the server 30 to be displayed on the display unit by a real-time display / instruction function.

  Next, the process of delegating the authority to issue an instruction to the work monitored by the monitor 2 to the other monitor in the operation PC 20 will be specifically described with reference to FIGS.

  As an initial state, it is assumed that the operation PC 20A is simultaneously monitoring work at points a, b, and c by the mobile terminal 10 at each point. When the monitor 2 operates the operation PC 20A and simultaneously monitors a plurality of operations, the simultaneous monitoring becomes difficult due to a problem or the like, and it becomes necessary to transfer the monitoring of the point c to another monitor 2 The monitoring person 2 who operates the operation PC 20A designates the authority delegation destination monitoring person 2 (or the operation PC 20B) to issue an instruction to work, and requests authority transfer. Then, when the delegation destination monitor 2 accepts the delegation of authority, the authority to monitor the work at the point c is delegated to the monitor 2 operating the operation PC 20B. The monitor 2 can also display the screen shown in FIG. 16 to determine the authority transfer destination monitor 2 after grasping the work status of the other monitor.

  Next, a specific procedure for delegating authority will be described with reference to FIG.

  First, the monitor 2 selects the personal list button from the command key, and displays the monitored work list (step S2701). Specifically, based on the work manual / work list data 33b stored in the storage unit 33 of the server 30, the work monitored by the monitor 2 by the EPSS function of the server 30 is read out as a work list. It is output to the operation PC 20. Next, the supervisor 2 selects a work to be delegated authority from the displayed work list (step S2702), and further requests authority delegation by clicking the authority delegation button displayed below the work list. (Step S2703). When the authority delegation is requested, the operation PC 20 generates the authority delegation pop-up screen shown in FIG. 28 by the authority delegation function and displays it on the display unit (step S2704). The monitor 2 selects the monitor to be delegated and inputs a message to the text area on the displayed authority delegation pop-up screen, and clicks the delegation button (step S2705). When the delegation button is clicked, the operation PC 20 displays a message on the display unit confirming authority delegation to the delegation destination monitor as shown in FIG. 29 (step S2706). And waits for the approval (step S2707). When the consent is not obtained from the delegation destination monitor (step S2707 / NO), the operation PC 20 again generates the authority delegation pop-up screen by the authority delegation function and displays it on the display unit (step S2704). The monitor 2 reselects the monitor to be delegated and re-inputs the message to the text area on the displayed authority delegation pop-up screen (step S2705). On the other hand, when the consent is obtained from the delegation destination monitor (step S2707 / YES), as shown in FIG. 30, the operation PC 20 displays a message on the display unit that the authority delegation is completed by the authority delegation function. (Step S2708).

  Note that when authority delegation is notified from the operation PC 20 by selecting a monitor and sending a message, the server 30 stores the monitor data 33a of the monitor selected by the operation PC 20 by the authority delegation function of the EPSS function from the storage unit 33. read out. Next, based on the supervisor data 33a read out by the authority delegation function of the MMoIP function, the operation PC operated by the supervisor selected in the operation PC 20 is notified of the authority delegation request. At that time, the message input in the operation PC 20 is also transmitted. When the server 30 receives notification from the delegation destination operation PC 20 that the authority delegation is accepted, the server 30 notifies the operation PC 20 of the fact by the authority delegation function of the MMoIP function. Further, the server 30 uses the authority delegation function of the EPSS function to monitor the work record ID, work date, worker, work place, target device and target part, work content, work manual 33b file name, work record video data. The general / link data 33a is updated by associating the file name 33c with the file name of the work recording voice data / work instruction voice data d. On the other hand, when the server 30 receives a notification from the delegation destination operation PC 20 that the authority delegation is rejected, the server 30 notifies the operation PC 20 of the fact by the authority delegation function of the MMoIP function. Then, the server 30 waits for selection of a new monitor.

  Here, the operation of the delegation destination operation PC will be described with reference to FIG.

  When the delegation destination operation PC receives the authority delegation request and message from the server 30, the authority delegation function displays the authority delegation pop-up shown in FIG. 32 and monitors whether or not to accept the authority delegation request. A member is inquired (step S3101). Then, when a button for accepting authority delegation is clicked by the monitor (step S3102 / YES), the operation PC causes the authority delegation function to display a message to the effect that the authority delegation shown in FIG. The server 30 is notified that the authority transfer is accepted (step S3103). The monitor selects the personal list button from the command key, displays the monitored work list, and confirms whether the authority has been transferred (step S3104). On the other hand, when a button that does not approve authority transfer is clicked by the monitor (step S3102 / NO), the operation PC notifies the server 30 that authority transfer is rejected.

  According to the above-described configuration, when the monitoring staff simultaneously monitors a plurality of work sites, when the simultaneous monitoring becomes difficult due to a problem or the like, the work on the work sites is monitored and an instruction is given. Since the authority can be delegated to other observers, even if the observer becomes unable to monitor, the mutual communication between the worker and the observer is carried out smoothly without interruption, and the authority to monitor the work on site Since the process of delegating to other observers is also quickly performed, the efficiency of the monitoring system can be improved.

  Next, a process of advancing work while the worker 1 who operates the mobile terminal 10 and the monitor 2 who operates the operation PC 20 jointly confirm the work will be described with reference to FIG. It is assumed that the indication board screen is already displayed on the mobile terminal 10 and the indication board is already displayed on the main window of the work sheet on the operation PC 20.

  First, the mobile terminal 10 monitors the check of the C button by the worker 1 using the real-time communication function, and when checked, notifies the server 30 to that effect (step S3401). The server 30 updates the work manual / work list data 33b stored in the storage unit 33 by the synchronization function of the EPSS function, and notifies the operation PC 20 that the C button has been checked by the status synchronization function of the MMoIP function ( Step S3402). When the operation PC 20 receives notification from the server 30 that the C button has been checked, the operation PC 20 updates the display of the C button of the corresponding step displayed on the indication board by the real-time display / instruction function (step S3403). On the other hand, the operation PC 20 monitors the check of the M button by the monitor 2 using the real-time display / instruction function, and notifies the server 30 of the check (step S3404). The server 30 reads the work manual / work list data 33b related to the update of the work manual / work list data 33b stored in the storage unit 33 and the work contents of the next step from the storage unit 33 and reads them. The work manual / work list data 33b is transmitted to the mobile terminal 10, and the mobile terminal 10 is notified that the M button has been checked by the status synchronization function of the MMoIP function (step S3405). When the mobile terminal 10 receives notification from the PC 30 that the work manual / work list data 33b related to the work content of the next step and the M button have been checked, the corresponding information displayed on the indication board by the real-time display / instruction function The display of the M button of the step to be updated is updated, and the work content of the next step is displayed based on the received work manual / work list data 33b (step S3406). When all steps are completed by checking the M button by the monitor 2, the server 30 notifies the mobile terminal 10 and the operation PC 20 of the completion of the work by the MMoIP function. The mobile terminal 10 and the operation PC 20 display a message notifying completion of work on the indication board.

  According to the above configuration, the center console and the maintenance console share the same work procedure manual, and the workers can complete each step by collaborating to confirm each step included in the work procedure. After confirmation, an experienced expert confirms through the video and audio sent from the work site and permits the progress to the next step. Can be prevented.

  Next, a process of switching the work site that is mainly monitored in the operation PC 20 in response to a call from the mobile terminal 10 will be described with reference to FIGS.

  First, the process of switching the main work site monitored by the operation PC 20 using the calling function will be described with reference to FIG.

  As an initial state, it is assumed that the center console 200 mainly monitors the maintenance console 100 at the site a and displays a work sheet corresponding to the site a on the display unit of the operation PC 20. Therefore, although the center console 200 is also in charge of monitoring work at the sites b and c, it is assumed that the work sheets for the sites b and c are not displayed on the display unit of the operation PC 20.

  When the center console 200 monitors a plurality of work at the same time, in order to prevent the confusion of the work contents, there is always one site to be monitored at the main, and the change to the monitoring of other sites is shown in FIG. This is due to the switching described above. As a result of this switching, the voice of the site that is not monitored by the main is not output to the center console 200. Therefore, when an inquiry or the like occurs from the center console 100, the call function described below is used for the center console 200. Make a call and request a switch to main monitoring.

  Here, it is assumed that a call is generated from the maintenance console 100 at the site c to the center console 200. Upon receiving the call, the center console 200 can switch to the main monitoring site by switching to the work sheet for monitoring the maintenance console 100 corresponding to the site c by the switching shown in FIG.

  Next, the monitoring switching processing procedure based on the calling function will be described with reference to FIG.

  First, the worker 1 selects the communication board button, displays the communication board screen on the display unit, and requests the monitor 2 to be called from the communication board screen (step S3501). Note that the portable terminal 10 operated by the worker 1 is not communicating with the operation PC 20 via the communication board, and the operation PC 20 is communicating with another portable terminal. When the call of the monitor 2 is requested, the mobile terminal 10 requests the server 30 to communicate with the monitor 2 in charge of the work site where the mobile terminal 10 is arranged by the call function (step S3502). Upon receiving a communication request with the monitor 2 from the mobile terminal 10, the server 30 reads out the monitor data 33e of the operation PC 20 that monitors the mobile terminal 10 from the storage unit 33 by the calling function of the MMoIP function (step S3503). Based on the monitor data 33e, the operation PC 20 operated by the monitor 2 is requested to communicate with the worker 1 (step S3504). When communication is requested from the server 30, the operation PC 20 displays a message to the effect that a call from another work sheet is transmitted on the work sheet monitored by the monitor 2 by the call function (step S3505). ). Then, the watcher 2 who sees the message selects the personal list button from the command key, displays the work list being monitored, and selects the work of the worker 1 who has called, and the work sheet is displayed. Then, the server 30 realizes communication between the supervisor 2 and the worker 1 by the video / audio communication function of the MMoIP function (step S3506).

  According to the above-described configuration, when the monitoring person simultaneously monitors a plurality of works on the operation PC, the work contents obtained by simultaneously displaying the work sheets for monitoring a plurality of sites are confused. If there is one work sheet displayed on the screen, the change to the monitoring of other sites is performed by switching the work sheet, and when the worker requests to switch the work sheet using the call function from the mobile terminal, By notifying the operation PC and prompting the operator to switch work sheets, it is possible to prevent confusion of work contents by monitoring multiple sites, and by calling up when the worker needs advice from the monitor Communication between the observer and the worker can be realized.
