  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the present embodiment, as will be described later, a function switching button for switching the functions of the first button group and the second button group included in the screen selection device is provided. When the function is switched by the function switching button, a desired time period is selected from the plurality of time periods by the first button, and a desired combination of monitoring parameters is selected by the second button from the plurality of groups.

  Thereby, according to this embodiment, the screen for monitoring a desired group by a desired time period can be selected easily, and the workability | operativity and usability of monitoring work improve.

  Before describing the embodiment, the configuration of the comparative example will be described with reference to FIGS. On the upper side of FIG. 8, parameter groups G11, G12,. . . It is shown. The parameter group includes one or a plurality of monitoring parameters of the plant monitoring device such as voltage, current, frequency, and temperature. The user can register the parameter group in advance using the client terminal 40, and can correct the registered parameter group.

  Parameter groups are created for different time periods (time axes T1, T2, etc.). Even if the combination of parameters to be monitored is the same, if the time axis is different, the parameter groups are different. A certain number of parameter groups can be registered for each time axis.

  The screen selection device 14P includes a plurality of push button groups 140P and 141P. Each of the push button groups 140P and 141P includes a plurality of push button switches. The push button switch is a hard switch that is manually operated by the user, and is different from a soft switch that is operated by an operation on the screen.

  One push button group 140P is a push button group for selecting a screen type. The other push button group 141P is a push button group for selecting a screen number. A combination of a push button for selecting a screen type and a push button for selecting a screen number is determined in advance for each time axis of the user arbitrarily designated trend screen. When the user operates the push button for selecting the screen type and the push button for selecting the screen number, the trend is displayed for the parameter group of the group (for example, the head) fixedly specified on the time axis corresponding to the combination. Is done. The trend display means displaying a time change of each monitoring parameter included in the parameter group based on a predetermined time axis.

  In the example of FIG. 8, when the user presses the screen type “# 3” from the screen type selection pushbutton group 140P and further presses “05” from the screen number selection pushbutton group 141P, plant monitoring is performed. A plant configuration diagram and the like are displayed on the display device 12 of the apparatus. When the user presses the push button with the screen number “06”, for example, a screen showing a time change of the parameter group G11 is displayed on the display device 12. Similarly, when the user presses the push button with the screen number “07”, a screen showing the time change of another parameter group G21 is displayed on the display device 12.

  Thus, when displaying a screen on the display device 12 incorporated in the plant monitoring device, the user selects the hard switches 140P and 141P dedicated to display screen selection provided on the monitoring panel.

  Here, the configuration of the monitoring panel will be described with reference to FIG. The monitoring panel 10 includes a monitoring console main body 11, a display device 12 provided on the rear side of the monitoring console main body 11, a control device operation switch 13 provided in front of the display device 12 and provided on the upper surface of the monitoring console main body 11. And a screen selection device 14. The screen selection device 14 in the embodiment and the screen selection device 14P in the comparative example are different in content, but the arrangement relationship in the monitoring panel 10 is the same, and therefore will be described using the configuration of FIG.

  As shown in FIG. 2, in a limited space located in front of the display device 12, various operation switches 13 for operating the control device and a screen selection device 14P composed of a plurality of pushbutton groups are arranged. Yes. Due to such physical limitations, it is difficult to greatly expand a dedicated hard switch for selecting a screen or to install an input device such as a pointing device and a keyboard on a desk. Furthermore, since the distance from the user to the display device 12 is also far away, even if the display device 12 is configured as a touch panel, it is difficult for the user to touch and operate the screen of the display device 12.

  Due to such physical constraints, the screen selection device 14P assigns the number of the monitoring screen to the push button (hard switch), and the user selects the push button corresponding to the number, thereby displaying the desired screen. 12 is displayed.

  FIG. 9 shows a method for selecting a screen. The plant monitoring device determines the screen type based on the push button input from the push button group 140P (S11), and further determines the screen number based on the push button input from another push button group 141P (S12). The plant monitoring device edits the screen display data (S13), transmits the screen display data to the display device 12, and requests screen display (S14).

  Monitoring of parameters by trend display is important for plant monitoring, and generally several types of screens are provided for displaying trends in a fixed combination of parameters suitable for the purpose. The user determines which screen to display according to the state of the plant.

  In addition, there is a demand for trend monitoring of various parameters according to more detailed circumstances. Therefore, as shown in FIG. 8, a trend display screen is prepared in which the user can arbitrarily specify the monitoring parameters by grouping them. On this trend display screen, a group (such as a head group) designated in advance among the monitoring parameters designated by the user is fixedly displayed. Other parameter groups can be monitored only by the dedicated client terminal 40 installed at the user's desk. The monitoring parameter group is also designated from the client terminal 40.

  For plant monitoring, monitoring by trend display arbitrarily designated by the user on the display device 12 incorporated in the monitoring panel 10 is important. Although the client terminal 40 also has a display function, the monitoring panel 10 is also provided with a control device operation switch 13 and the like, and can respond immediately, so the display device 12 is the center of monitoring. On the other hand, the parameter to be monitored changes depending on the state of the plant. However, in the screen selection method shown in FIG. Yes, it is difficult to respond immediately, and it is not easy to use.

A configuration may be used in which an unused switch among the control device operation switches 13 is used as the mode transition button 1400.

  In the normal mode, as described in FIGS. 8 and 9, the first push button group 140 provides a screen type selection function (first function) for selecting the screen type, and the second push button group 141 displays the screen number. A screen number selection function (second function) for selection is provided.

  When the user presses the mode transition button 1400, the first push button group 140 provides a time axis selection function (third function) for selecting a time axis instead of the screen type selection function. Similarly, the second push button group 141 provides a group number selection function (fourth function) for selecting a group number instead of the screen number selection function.

  In the state of transition to the trend display mode, the user selects a push button corresponding to a desired time axis from the first push button group 140. Further, the user selects a push button corresponding to a desired monitoring parameter group from the second push button group 141. Thereby, the plant monitoring apparatus 1 displays the data regarding the designated parameter group on the display device 12 on the designated time axis.
