Abstract

PURPOSE:To reduce the size of a control panel by giving a touch to a plant equipment on a plant flow chart displayed on a display means to select the corresponding operation plant equipment and then giving a touch to the operating switch of the plant equipment displayed on the same screen. CONSTITUTION:The measurement signal given from a measuring instrument 1 is synthesized with the image data selected out of a image data storage device 2 via an image selecting keyboard 3 by an image synthesizing device 4. This synthesized image data is supplied to a CRT 5. A touch screen 6 supplies the signal showing the position on a screen touched by an operator to a controller 7. The controller 7 refers to this signal and the image data stored in an image data storage device 2 to display the image data of the operating switch of the plant equipment touched on the CRT 5. The second touch is given to the displayed operating switch and the screen 6 sends the touch position signal. Thus the controller 7 sends the control signal corresponding to said touch position signal to the plant device.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a plant monitoring and control device that monitors and controls the operation of a large-scale plant such as a nuclear power plant.

[Technical background of the invention and its problems] Conventionally, in large-scale plants such as nuclear power generation plants, various indicators and operations necessary for plant monitoring and control have been installed so that the plant can be monitored and controlled in one place. The equipment is placed on a control panel in the central control room, and is used to monitor and control the entire plant. For this reason, as the number of objects to be monitored and controlled increases, the number of these devices also increases, and controllability increases.
There was a problem that not only did the panel become larger, but the burden on the operator also increased.

Recently, in order to downsize control panels and reduce the burden on operators, touch screens that can detect touch positions by directly touching them with a finger have been placed on top of cathode ray tubes (CRTs) to improve plant control. Plant monitoring and control devices that perform monitoring and control have been devised. In plant monitoring and control equipment using such touch screens, conventional mechanical operation switches are displayed as images on a CRT equipped with a touch screen, and operators can control the plant by touching them with their fingers. This makes it possible to control.

However, in plant monitoring and control equipment that uses such images, if there are many operation switches arranged in the image, it takes time for the operator to search for the operation switch to operate on the screen. There was a problem. Furthermore, since the image used for plant control in this method is only a screen display of mechanical operation switches, another CRT is required to display the operating status of the monitored object that needs to be monitored along with control. There was also the issue of necessity. Therefore, with conventional devices of this type, it has not been possible to significantly reduce the burden on the operator and downsize the control panel.

[Object of the invention] The present invention has been made in response to such conventional circumstances,
The present invention aims to provide a plant monitoring and control device that can reduce the size of the control panel and reduce the burden on operators.

[Summary of the Invention] The present invention provides a measuring means for measuring the operating state of a plant installed in each part of the plant, an image of the plant system diagram, and an image of the operation switches of the plant equipment included in the plant system diagram. An image data storage means for storing image data, a plant system diagram that reads out the image data stored in the image data storage means and shows the current operating status based on the measurement results of the measurement means, and an arbitrary system diagram included in this plant system diagram. An image synthesis means for synthesizing images of operation switches of a plant system diagram, an image display means for displaying an image synthesized by the image synthesis means, a touch screen disposed over the image display means, and an image display. Displaying on the image display means an image of a plant system diagram showing the current operating status synthesized by the image synthesis means in response to the command, and displaying any plant equipment displayed on the image display means from the touch screen. A plant system diagram synthesized by the image synthesizing means and an image of the operation switch of the plant equipment are displayed on the image display means by a corresponding touch position signal, and a touch position signal from the touch screen corresponding to the operation switch is displayed on the image display means. This plant monitoring and control device has a control panel that outputs a control signal corresponding to the operation of the operation switch to the control system of the plant equipment, thereby reducing the size of the control panel and reducing the burden on the operator.

[Embodiments of the invention].

The details of the present invention will be explained below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of this embodiment, and in the figure, reference numeral 1 indicates measuring instruments installed in each part of the plant.

The measurement signal from this measuring device 1 is stored in an image data storage device 2.
The image data selected by the image selection keyboard 3 from among a large number of image data stored in the .

A touch screen 6 is superimposed on the screen of the CRT 5, and the touch screen 6 supplies a touch position signal indicating the position on the screen touched by the operator to the control device 7.

Upon receiving the touch position signal, the control device 7 refers to the touch position signal and the image data stored in the image data storage device @2, and identifies the touched plant equipment.
The image data of the touched operation switch of the plant equipment is called from the image data storage device 2, the image of this operation switch is combined with the image displayed on the CRT 5 by the image composition device 4, and this image is displayed on the CRT 5. let

When the operator touches the displayed operation switch again and the touch screen 6 sends out a touch position signal,
The control device 7 sends a control signal corresponding to this touch position signal to the plant equipment.

FIG. 2 is a diagram showing an example of an image showing operating status information displayed on the CRT 5. In the figure, reference numeral 8 indicates the plant system of the residual heat removal system, cooling system, and emergency equipment cooling system in a boiling water reactor. The figure shows. The display symbols displayed in this figure are, for example, as shown in FIG.
It shows the operating status of the plant equipment. In this figure, symbols 9a and 9b indicate stopped and running pumps, respectively, and symbols 10a, 10b,
Symbols indicated by 10C indicate closed, intermediate, and open valves, respectively. Symbols indicated by symbols 11a and 11b indicate main piping with an unsecured flow path and a secured flow path, respectively, and symbols indicated by the symbol @12. indicates sub-piping, code 13
Symbols a and 13 each indicate the system operation in the FF5ON state. This display is cyan when the operating state of each plant equipment is normal, red when it is abnormal, and green for static equipment such as tanks and heat converters.

Such images are transferred from the image selection keyboard 3 to the control device 7.
Based on the image selection signal sent from the image data storage bag M2, the image data read from the image data storage bag M2 and the measurement data sent from the measuring instrument 1 are combined by the image synthesis device M4 and displayed on the CRT 5.

At this point, for example, if an operator touches a plant device on the plant system diagram displayed on the CRT5, the CRT5
A touch screen 6 disposed overlappingly on the screen sends a touch position signal to a control device 7 as X-Y coordinates.

At this time, the control table @7 starts operating in response to this touch position signal, and performs the processing shown in FIG. 4.

That is, first, the control device 7 inputs the touch position signal sent from the touch screen 6A), and records which plant equipment displayed on the CRT 5 is touched in the input touch position signal and the image data storage device 2. Identification is made by comparing and collating with stored image data (B).

Next, the control table W7 reads the image data of the touched plant equipment operation switch from the image data storage device 2, inputs this image data to the image composition device 4, and displays this operation switch at the bottom of the screen of the CRT 5. (C).

Note that the display patterns of the operation switches displayed at this time differ depending on the plant equipment, and the storage device 2 stores which plant equipment corresponds to which operation switch display pattern.

At this point, the control device 7 waits for the operator to touch the touch screen again (D).

When the operator touches the touch screen 6 again and a touch position signal is sent out, the control device 7 again identifies what was touched on the screen in the same manner as described above (E).

At this time, if the touch is on the operation switch, the control device 7 sends a control signal corresponding to the touched operation switch to the plant equipment (F) and ends the operation.

Furthermore, if the touch is made to the plant equipment that was touched immediately before, the control device 7 sends an image display command to the image synthesis device 4 to erase the operation switch that has already been displayed from the screen ( G), end the operation.

In addition, if the touch is made to a plant device different from the one touched immediately before, the control device 5 erases the currently displayed operation switch from the screen and responds to the newly touched plant device. An image display command for displaying the operation switch to be touched is sent to the image synthesizing device 4 to prepare for the next touch.

Note that the display of the operation switches performed at this time is performed as shown in FIG. In this figure, the symbol @14 indicates an operation switch.

In the plant monitoring and control device configured as described above, the plant equipment to be operated is selected by touching the screen on the CRT5 that displays the plant system diagram showing the operating status with a finger, and the displayed information is displayed in response to this selection. Operation switch 1
After confirming that the selected device is correct, touch 4 to perform the operation. Therefore, since it is a two-step operation, the possibility of erroneous operation is reduced and highly reliable operation can be performed. If the selected plant equipment is incorrect, it is possible to touch the previously touched equipment again to end the operation, or touch the correct equipment again to display the correct operation switch 14. . In this way, a single CRT can simultaneously display the plant operating status and the operating switches for the equipment being operated, allowing operations to be performed while monitoring the operating status, greatly reducing the burden on the operator. It is also possible to downsize the control panel.

Note that although the above explanation assumes that the operation is performed using a touch screen, it is also possible to use a method of instructing with a light ben on the CRT or a method of moving the cursor on the CRT using a keyboard operation without using the touch screen. .

[Effects of the Invention] As described above, in the plant monitoring and control device of the present invention, a plant system diagram showing the operating status of the plant is displayed on one display means, and the plant equipment on the plant system diagram is touched. This allows the plant equipment to be operated by selecting the plant equipment to be operated and touching the operation switch of the plant equipment displayed on the same screen. Therefore, the number of display means can be reduced and the control panel can be downsized, and the number of display means that the operator must monitor can also be reduced, making it possible to significantly reduce the burden on the operator.
