Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a plant monitoring and control device that monitors and controls the status of an industrial plant.

[Conventional technology]

Plant monitoring equipment has a huge number of switches, lamps, meters, recorders, etc. arranged on its large panel, and the number tends to increase as the size of the plant to be monitored increases. The major challenge is how to reduce the space required for this arrangement.

For example, as shown in Japanese Patent Laid-Open No. 60-54017, plant information is displayed on the screen of a CRT for plant monitoring, while images of operation switches, etc. are displayed on the screen of another CRT for operation. A plant monitoring and control device has been proposed in which a desired operation switch image can be selected using a touch switch attached to the surface of the screen of the operation CRT to perform the desired operation.

[Problem that the invention seeks to solve]

However, when monitoring the plant while looking at the screen of the plant monitoring CRT, if it becomes necessary to display plant information for a specific part, the operator can
After turning your gaze to the screen and switching the screen, turn on the monitoring C.
Since the operator has to look at the RT screen again, his/her thoughts are temporarily taken away from "monitoring". As a result,
There was a problem in that continuity of thinking during monitoring could no longer be maintained, plant information could be misunderstood, and smooth monitoring activities could no longer be continued.

An object of the present invention is to provide a plant monitoring and control device that can smoothly monitor plant information without interrupting thinking during monitoring activities.

[Means for solving problems]

The present invention provides a screen that displays multiple types of operation contents for the displayed contents on a part of the display screen of a display device that displays plant information, and detects which operation contents the operator's line of sight is focused on. A device equipped with a gaze position detection device and a switch that instructs the execution of the operation being watched, and configured to change the displayed content to correspond to the operation the operator was staring at immediately before operating the switch. It is.

[Effect]

For example, "
"Enlarge", "Analog trend data display".

Display something like "Always return to screen". Therefore, when the operator turns on the switch while observing the operation content, for example, "enlarge," the currently displayed plant information is enlarged and displayed.

Therefore, since the operator only has to move his/her line of sight within the range of one CRT screen, there is no interruption in thinking about monitoring activities.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram showing an embodiment of a plant control device according to the present invention.

In the figure, a large display device 1 is composed of a plant monitoring operation display section 2 that displays the status of the plant, and a switching selection section 3 that displays a plurality of types of operation contents for the display contents of the display section 2. , display data for display is provided from the computer system 4. A screen gaze position detection device 5 and an operation switch 6 are connected to the computer system 4, and a plant 7 to be monitored is further connected.

Here, the screen gaze position detection device 5 detects which position of the display section 2 or the selection section 3 the line of sight of the operator R8 is directed to, and uses an eye camera fixed to the head or neck of the operator, etc. It is configured.

In the above configuration, a constant monitoring screen is displayed on the plant monitoring operation display section 2 of the large display device 1 by the computer system 4. Therefore, when it becomes necessary for the supervisor 8 of the plant 7 to view detailed data on the state of the plant 7, the supervisor 8 displays the display on the switching selection section 3 of the large display device 1 via the screen gaze position detection device 5. Among the contents, for example, the operator turns on the operation switch 6 while observing the display "Analog Trend" as shown by the broken line 9. Next, the supervisor 8 moves his line of sight to the position where the "analog trend" is to be displayed in the plant monitoring operation display section 2 of the large display device 1, and displays the plant information at this position as shown by the broken line 10. Turn on the operation switch 6 while watching carefully. By this operation, the computer system 4 displays an analog trend screen in the receiving section 2 (to the plant monitoring operation table C instructed by the supervisor 8).

Therefore, it is possible to switch screens without taking your eyes off the monitoring screen.

Here, the principle of identification of the line of sight in the screen gaze position detection device 3 will be explained using FIG. 2.

In order to determine the gaze position on the screen based on the line of sight of the observer 8, first, a line of sight detection device 11 that detects the line of sight and a two-dimensional position detection device 12 that detects the spatial position of this line of sight detection device 11 are required. Become.

In order to detect the spatial position of the line-of-sight detection device 11, the line-of-sight detection device 11 transmits the viewing plane position detection signal 13 in three directions facing the plant monitoring operation display unit 2: left, right, and back. Receive and detect spatial position 2
The dimensional position detection device 12 may be arranged in three directions. The viewing plane center 14 is determined by the three position signals derived from these two-dimensional position signals 12. In this case, when the direction of the line-of-sight detection device 11 changes according to the movement of the observer's head, the visual field position detection signal 13 is transmitted to the two-dimensional position detection device 12.
Since the position of incidence on the light also changes, the center of the visual field at this changed position becomes the line-of-sight direction 15. If the direction of the line of sight is known, it is possible to identify which position on the display screen the user is gazing at by referring to the height of the eyes from the horizontal plane and the height of the display screen.

Next, the line of sight detection device 11 attached to the head or neck of the observer 8 is equipped with a light emitting device 16 and a two-dimensional light receiver that detects the position of the reflected light from the operator's eyeball 17, as shown in FIG. 2(b). The position detection device 18 detects the direction of the line of sight.

Since the direction of the line of sight does not necessarily match the movement of the head, it may be determined by paying attention to the fact that the position of the reflected light changes depending on the direction of the eyeball 17.

FIG. 3 is a flowchart showing the procedure for changing the display content on the display unit 2, and FIG. 4 is a functional block diagram functionally showing the internal configuration of the calculation system 4.

In these figures, the content of the constant monitoring screen is displayed on the display unit 2, but the operator 8
When you turn on the operation switch 6 while gazing at the screen, the screen gaze position detection device 5 outputs the display position information of "analog trend" in the switching selection section 3, and the operation switch 6
An on-operation signal is output from. Therefore, the computer system 4 determines that the "analog trend" display has been selected by the position determination # control section 40, and stores this determination result in the switching selection mode storage section 41.

Next, when the operator 8 looks at the target part of the "analog trend" and turns on the operation switch 6, the computer system 4 displays the position of the plant information displayed on the display unit 2 that was looked at by the operator 8. The plant information is determined by the position determination control unit 40. After that, the screen switching control section 42 moves to the screen switching control section, retrieves the "analog trend" mode information stored in the storage section 41, and sends it to the plant status input/output control section 44 and the screen display control section 43. output the necessary commands.

The plant status input/output control unit 44 collects data from the plant 7 as needed and links it to the screen display control unit 43. The screen display control section 43 displays the "analog trend" at a designated location on the plant monitoring operation display section 2 of the large display device 1 when the "analog trend" data is complete.
Display.

FIG. 5 shows an example of the "Plant Summary Display" screen displayed on the plant monitoring operation display section 2 of the large display device 1.
The figure shows a screen example of the "analog trend" display.

As described above, according to this embodiment, it is possible to switch screens without taking one's eyes off the monitoring screen, and smooth monitoring is possible without losing the continuity of human thought. Another advantage is that display information for a portion of interest can be quickly changed while monitoring the entire image.

In the above embodiment, the configurations of the plant monitoring operation display section 2 and the switching selection section 3 of the large display device 1 are distributed as shown in FIG. The layout can be freely set. Also,·
The display contents of the switching selection section 3 are also not limited to the embodiments. Further, the operation switch 6 may be not only a switch operated by hand, but also a switch operated by foot or voice, and any switch that can display an operation may be used. Furthermore, although the screen gaze position detection device 5 is in the form of glasses, it may be of any configuration as long as it can detect the line of sight of the observer 8 and identify the gaze position on the screen.

〔Effect of the invention〕

As described above, according to the present invention, since the display screen can be switched while monitoring the entire plant monitoring screen, it is possible to quickly switch the display information of the focused part while monitoring the entire plant. Become. ■Screen information can be changed by simple operations (visual inspection, turning on the operation switch), making it possible to perform monitoring without placing an extra burden on plant monitors. ■Since you can switch screens without taking your eyes off the monitoring screen, continuous monitoring becomes possible, and you can quickly respond when an abnormality occurs. ■Switches required for screen switching operations are simplified, making it ideal for plant monitoring rooms.
