Description

  The present invention relates to a GUI for displaying a trend graph for monitoring control, and more particularly to a scale display method in trend graph display of a plurality of measurement / recording channels.

  In various types of monitoring control systems, measurement data and control data to be monitored and controlled are displayed on a monitoring screen to enable monitoring and operation by an operator. A GUI (graphical user interface) is adopted for display control of the monitoring screen, and a measurement trend graph display for displaying measurement data in a graph in real time and a recording trend graph display for displaying file-logged data in a graph in a historical manner are performed.

These trend graph displays have a display control function that allows multiple channels of data to be displayed on a single screen in order to make monitoring and monitoring status easier to understand. The vertical and horizontal axes of the display frame are scales for each data ( Values and instruction lines) are displayed so that rough values of the data can be read, and the legends (group names and attributes of the data) are displayed in a list for each display data outside the frame (for example, Patent Document 1 and Patent Document 2). reference).

  When displaying a plurality of channel data on one screen, the range (scale, unit, etc.) of each data is often different. In this case, the scale display is performed by superimposing the scales for each channel data or by dividing the display on the left and right sides of the display frame.

  In such a scale display control method, there are problems such as making it difficult to associate the data with the scale, and reducing the trend graph display frame when trying to display a large number of scales for each data of many channels. there were.

  An object of the present invention is to make it easy to associate each data with its scale without changing the size of the data display area and the scale display area to display a plurality of data on one screen and a scale display for each data. To provide a trend graph display method.

  In order to solve the above-described problem, the present invention solves the problem of the display position and display order of the scale of the selected display data when the scale for each display data is selected, depending on the sharing, position and order of the other scales. And is characterized by the following method.

(1) A GUI for displaying a trend graph on a display device displays a plurality of trend graphs in a trend graph display area of one screen, and displays each trend along the horizontal axis and the vertical axis or the circumferential direction of the trend graph display area. A trend graph display method for displaying a plurality of scales for each graph,
The GUI is
A scale selection control step for selecting the scale selected by the check operation of the check box for each display data or the selection operation of the radio button for each display data,
A scale position control step for displaying one or more scales side by side in a scale display area in which the selected scale is arranged at a position closest to the trend graph display area;
When displaying a plurality of scales in the scale display area, a scale order control step for controlling the display order of the scales and the display order accompanying the change of the scales;
It is characterized by having.

  (2) The scale selection control step includes a step of selecting, as the shared scale for the display data, when the same scale is used for each display data.

  As described above, according to the present invention, when a scale for each display data is selected, the display position and the display order of the scale of the selected display data are controlled according to sharing with other scales, the position, and the order. Therefore, it becomes easy to associate each data with the scale without changing the size of the data display area and the scale display area to display a plurality of data and a scale for each data on one screen.

  FIG. 1 is a main part configuration diagram of a trend graph display device showing an embodiment of the present invention, which is realized by computer resources for constructing a monitoring control system and software using the same.

  The display device 10 displays various monitoring screens, and displays a trend graph as one of them. The GUI 20 performs display control of the display device 10. This display control includes display control according to operation input by the operation input unit 30 such as a keyboard and a mouse of the operation input unit 30, and real-time data collected by the data management unit 40. And display control using file data stored in a database.

  In the figure, a screen displaying a trend graph on the display device 10 is shown. In this screen configuration, the trend graph display area 11 of the voltage or frequency to be monitored is arranged at the center of the screen, the scale display areas 12 and 13 are arranged at the nearest positions on the vertical axis on both sides, and the horizontal axis on the lower side. The scale display area 14 is arranged at the nearest position, and the legend display area 15 classified by data item is arranged further to the right of the scale area 13. Further, display areas 16 to 19 for command input buttons and radio buttons are arranged near the upper and lower ends of the screen.

  For these basic screen displays, the screen display control unit 21 of the GUI 20 performs display processing of screen display components based on the screen configuration data, and the measurement / recording data acquired from the data management unit 40 by the graph display control unit 22. The display is controlled in the trend graph display area 11 by adjusting the scale.

  In addition to the screen display control unit 21 and the graph display control unit 22 described above, the GUI 20 includes a scale position control unit 23, a scale order control unit 24, and a scale selection control unit 25, and these control units 23 to 25 provide a scale display area. The scale display control is performed. Hereinafter, the scale display control will be described in detail.

(A) Scale position control The scale position control unit 23 arranges one or more scales in the horizontal direction in the scale display areas 12 and 13 arranged at positions closest to the vertical axis of the trend graph display area. Display position control is performed, and the display area 12 or 13 is controlled when the position control is performed.

  Note that the scale display area 14 on the horizontal axis often has the same scale for each display data. In this case, one scale is selected and its position is controlled. Take control.

(B) Scale order control When the scale order control unit 24 displays a plurality of scales in the scale display area 12 or 13, the scale order control unit 24 controls the display order of the scales and the display order associated with the change (deletion, addition) of the scales. .

(C) Scale selection control The scale selection control unit 25 selects a scale selected and operated for each display data by the operation input unit 30 from scale data stored in the data management unit 40. If the same scale unit (electricity, position, pressure, etc.) and scale (equal interval, logarithm) are used for each display data, these display data are grouped and the scale is selected as a shared scale for each group. To do.

  This scale selection is performed by checking a check box for each data item displayed in the legend display area 15 using the operation input unit 30 or by selecting a radio button.

  The scale display control by the control units 23 to 25 will be described with the following specific example.

  FIG. 2 shows a case where five pieces of display data (DATA1 to DATA5) are displayed, while three scales (scale 1 to scale 3) are displayed on the vertical axis in the scale display control.

  In this case, in the scale selection control, scale 1 is assigned to DATA1, DATA4, and DATA5 as the same scale group, scale 2 is assigned to DATA2, and scale 3 is assigned to DATA3 according to the selection by the check box of legend display area 15. In the scale position control and the scale order control, the scale 2 is displayed on the left side of the scale 1 because the display position is “2” on the left side of the trend graph display area 11, and the scale 3 is the trend display position. Since it is on the right side of the graph display area 11, it is displayed on the right side of the trend graph display area 11.

  In the display state of FIG. 2, when the selection of the scale display of DATA1, DATA4, and DATA5 is turned off, the scale 1 assigned to the scale position control is not displayed as shown in FIG. Then, scale 2 is displayed with right justification. Even when the scale display selection is turned off, the “scale filling” control is not performed when another scale is used.

  Further, when only one scale is displayed in the scale display area 12 or 13, in the scale position control, the position closest to the trend data display area 11 is selected as shown in FIG. The scale display position.

  In the embodiment, by performing display color control in which the display data and the scale have the same color, recognition that associates the display data with the scale can be further facilitated.

  In the embodiment, a rectangular data display area having a vertical axis and a horizontal axis is shown. However, a circular data display area having a scale display area on the X and Y axes or a scale display area in the circumferential direction; It can be applied to achieve the same effect.
