Abstract

PURPOSE:To grasp quickly and accurately the detailed information of a plant by displaying a menu screen on a CRT display device and supplying a specific area with touch through a coordinate input device. CONSTITUTION:A supervisory unit for plant operation state processes the measurement signals S1 supplied to an electronic computer 1 from various measuring instruments at each place of a plant via input terminals 1a-1m and produces plural state signals S3 to show the plant operation states. The computer 1 is connected to a keyboard 2 and selects the signal S3 to supply it to a CRT display device 3 in response to the input of the display request signal S2. Thus a specific picture is displayed by those selected signal S3 on a CRT display device 3. While the input signals Sx and Sy are fetched from a coordinate input device 4 set on the device 3. Then a touch area is calculated. Thus if the water level of a reactor has a drop in an atomic power plant, for example, a detailed screen about said drop is selected by the touch input out of the displays of the device 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a plant operating state monitoring device that monitors the operating state of a plant such as an atomic couplant or a chemical plant to ensure plant safety.

[Technical background of the invention and its problems] Conventional monitoring devices that monitor the operating status of plants such as atomic couplants or chemical plants electronically transmit measurement signals such as process quantities from various measuring instruments installed in various parts of the plant. The operating status of the plant is monitored by processing it with a computer, etc. to obtain multiple status signals that indicate the status of the plant, and then indicating and recording these status signals using a meter such as a needle indicator or a recorder. It is configured. Therefore, in conventional monitoring devices, it is necessary to install separate meters and recorders for each type of signal indicating the operating status of the plant. For this reason, when there are many types of signals to be monitored, such as in an atomic coupler, there will be a large number of meters and recorders, and the monitoring panel will inevitably have to be large. The problem was that a large number of meters and recorders had to be monitored, which placed an excessive burden on the operator.

Therefore, in order to downsize the monitoring panel and reduce the burden on operators, cathode ray tube displays (hereinafter referred to as CRT displays) have recently been used as indicators to display the operating status.
A system has been proposed in which a T-display is configured to switch and display a plurality of plant state quantities at appropriate times. According to such a monitoring device using a CRT display, a plurality of types of plant operating status quantities can be displayed on one CRT display, so that the monitoring panel can be made smaller.

However, in the above-mentioned monitoring device using a CRT display, multiple screens are assigned to one CRT display and the screen to be monitored is appropriately selected by keyboard operation, etc. It was impossible to obtain information that was not directly relevant. Furthermore, even if you select a specific screen using the keyboard, for example, in a large plant such as a nuclear power plant, the number of plant state quantities will be quite large, and the number of screens that aggregate them will be 100 or more.
Since there are up to 200 sheets, it is difficult to make an appropriate selection. Therefore, it is almost impossible to sequentially monitor trends, current values, and set values for determining the presence or absence of plant abnormalities of individual plant status quantities in a shorter time, and it is difficult to respond quickly in an emergency. There was a problem that I couldn't do it.

[Purpose of the Invention] The present invention has been made in view of the above circumstances, and its purpose is to quickly and accurately monitor and take countermeasures when an abnormality occurs in a plant, and to reduce the burden on operators. Plant operating status! ! An object of the present invention is to provide a monitoring device.

[Summary of the Invention] In order to achieve the above object, the present invention includes a status signal generation device that obtains a plurality of status signals indicating the operating status of the plant based on measurement signals obtained from measuring instruments attached to the plant. , a plurality of cathode ray tube displays that display each status signal obtained by the status signal generation device as a specific image, a coordinate input device provided on the display screen of the cathode ray tube display, and a coordinate input device provided on the display screen of the cathode ray tube display; The device includes a display device that displays a menu screen showing a list of names of individual plant state quantities, and a sorting device that sorts the name list menu by name, and the divided specific area corresponding to the coordinate input device. The present invention relates to a plant operation status monitoring device that displays detailed information such as trends and current values of plant status III related to the name in the specific area on the display screen of the cathode ray tube display device by touching the button. .

[Embodiments of the invention] An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic block diagram of a plant operating state monitoring device that is an embodiment of the present invention.

In the figure, measurement signals S1 from various measuring instruments (not shown) installed at various locations in the plant are sent to an electronic calculator 11 via input terminals 1a, Ib, . . . , 1m of an electronic meter*i.
1 is input. In this electronic calculation 111, measurement signals S1 inputted from the various measuring instruments are processed to generate a plurality of status signals indicating the operating status of the plant.

By the way, this computer 1 is connected to a keyboard 2, and when the display request signal S2 from the keyboard 2 is input, the display request signal S2 is selected from among the plurality of status signals.
2 is selected and supplied to the CRT display 3.

Therefore, the CRT display 3 is configured to display the status signal S3 supplied from the electronic computer 1 as a specific image.

Further, the electronic computer 1 receives status signals S from the various measuring instruments mentioned above.
In addition to processing 3, the display screen of CRT display 3 (
It is configured to take in input signals 3x and sy from a coordinate input device M4 mounted on the screen) and determine the area touched by the operator. Here, the screen to be displayed on the CRT display 3 is displayed not as a plant status signal but as a menu screen showing only the names of those screens, and the area determined from the input signals 3x and sy from the coordinate human power device i4, A name screen that matches the specific name of the displayed menu screen is displayed on the CR7 display 3. In addition,
The menu screen is displayed on the CR7 display 3 by inputting from the keyboard 2. The coordinate input device 4 is, for example, a touch screen device as shown in FIG. Corresponding X and Y coordinates are input to the computer 1.

Further, as shown in FIG. 3, the menu screen has a total of 15 items (1-1,
..., 1-5. 2-1. ...2-5. 3-
1. ...3-5), and the name of the screen showing the plant status is displayed in each of the 15 categories. Then, the CR7 display 3 displays a screen with the name appearing in the specific area where the touched coordinate position matches the 15 divided positions.

Note that although the divisions of the menu screen are approximately equal in the figure, it goes without saying that the size of each division may be set to any size as appropriate, taking into account the amount of information and the like.

Next, the operation of this embodiment configured as described above will be explained.

For example, if the water level of a nuclear reactor in a nuclear power plant drops, an operator selects a menu screen using the keyboard 2. Then, the user touches with his/her finger a detailed screen regarding the reactor water level in the menu screen displayed on the CR7 display 3, for example, the screen portion of section 2-3, and inputs the touched coordinates into the computer 1. Then, category 2-
3, a detailed screen regarding the reactor water level is displayed. This screen shows, for example, the water level trend.

Information on direct water levels such as current values and various set values for determining the presence or absence of an abnormality, and aM information such as "feed water flow rate and outflow steam flow" are included.

In this way, by displaying the menu screen on the CR7 display 3 and using the coordinate input device M4, detailed information about the plant can be grasped quickly.

In this embodiment, when enlarging the menu screen, selection is made from the keyboard 2, but if a menu screen selection area is provided in a part of the detailed monitoring screen, the menu screen can be similarly selected from the CRT screen. becomes possible.
