Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a plant operating state monitoring device for monitoring the operating state of, for example, an atomic or chemical plant to plan 1 to ensure safety.

[Technical background of the invention]

Conventionally, this type of monitoring device processes measurement signals such as process quantities from various measuring instruments installed in various parts of the plant using an electronic computer to obtain multiple status signals indicating the status of the plant. It is configured to monitor the operating status of the plant by giving instructions and recording using meters such as indicators and recorders. Therefore, in the past, it was necessary to install separate meters and recorders for each type of signal that indicates the operating status of the plant. This has the disadvantage that the number of meters and recorders is large, the monitoring panel is large, and the burden on the operator is heavy because the operator has to monitor a large number of meters and recorders.

Therefore, recently, cathode ray tube displays (hereinafter referred to as CRT displays) have been used as indicators to display the operating status in order to downsize monitoring panels and reduce the burden on operators.
A display device is being considered in which multiple types of plant state quantities are switched and displayed at appropriate times. According to this monitoring device using a CRT display, a plurality of types of plant operating status quantities can be displayed on one CRT display, so the monitoring panel can be made smaller. However, since this monitoring device using a CRT display allocates multiple screens to one CRT display and selects the screen to be monitored as appropriate by keyboard operation, etc., while a certain screen is being displayed, If an abnormality that is not directly related to the above occurs, there is a problem in that the occurrence of the abnormality cannot be detected from the currently displayed screen. Therefore, as a means to improve this point, for example, CRT
One idea is to provide an area for anomaly notification on a part of the screen of the display so that when an anomaly occurs, the occurrence of the anomaly is commonly reported regardless of which screen is being displayed.

However, the above means only notifies the occurrence of an abnormality, but does not notify which screen the abnormality corresponds to. Therefore, in order to promptly display the screen corresponding to the abnormality, the operator must memorize the contents of the abnormality and the correspondence between the screens in advance, which further increases the burden on the operator.

[Problems with background technology]

Various proposals have been made as a means to eliminate the negative 10 increase in the number of people involved in driving H, and one of them that is currently in practical use is an automatic hit screen method. This automatic human screen method displays the screen related to the system in which the abnormality has occurred and the corresponding C
This is automatically displayed on the R7 display, and the operator must
It has the advantage of being able to instantly determine to which system the abnormality belongs just by looking at the content displayed on the screen of the T display. However, if the number of CRT displays used in the monitoring equipment is small, it can be recognized in a short time that the automatic hit screen is displayed, but if there are many CRT displays, such as in the central control room of a recent nuclear power plant,
When T-displays are used and the number of operators is small (2 to 3), the number of CRT displays monitored by one person is 7.
~10 units, which is a considerable number. Therefore, even if an auto-hit screen is displayed on a certain CRT display, it is difficult to recognize the auto-hit CRT display in a short time. Furthermore, it becomes difficult to cope with the case where a plurality of CRT display devices continuously display automatic hit screens.

[Purpose of the invention]

The present invention was made based on the above circumstances, and its purpose is not only to reduce the size of the monitoring panel, but also to automatically display a specific image according to the abnormality when an abnormality occurs in the plant. It is displayed on the CRT display and automatically informs the operator that a hit has occurred, allowing the operator to immediately recognize the location of the abnormality, allowing prompt and accurate monitoring and response measures, and reducing the burden on the operator. The purpose of this project is to provide an operating state CI visualization device for extremely useful plans for safe plant operation.

[Summary of the invention]

In order to achieve the above object, the present invention displays the operating status of a plant as a plurality of specific images on a plurality of CRT displays, and when an abnormality occurs in the plant, an automatic hit screen corresponding to the abnormality is displayed. Automatically displays on the CRT display, and notifies the operator that the CRT display has been automatically hit by an automatic hit status display installed near the CRT display, and the operator immediately monitors the automatic hit screen. It was made so that it could be done.

[Embodiments of the invention]

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 and 2 are diagrams showing an embodiment of the present invention, and FIG. 1 is a block diagram showing a schematic configuration of Plan 1 to an operating state monitoring device according to an embodiment of the present invention. In the figure, 1 is an electronic computer that processes measurement signals from various measuring instruments (not shown) installed at various locations in the plant. This computer 1 is connected to the various measuring instruments mentioned above through input terminals 1a, 1b, . . . , 1n, and processes signals from the various measuring instruments to form a plurality of status signals indicating the operating status of the plant It is something.

Moreover, this electronic tightening machine 1 has a plurality of keyboards 2a, 2b.

Furthermore, the electronic meter sieve 1 is designed to detect abnormalities in the plant when processing signals from the various measuring instruments described above. That is, when this electronic calculation 1111 detects an abnormality in the plant based on signals from various measuring instruments, it calculates an abnormality type number, a corresponding image number corresponding to this abnormality number, and a corresponding image number according to the type of the abnormality. Then, the image corresponding to the corresponding image number is automatically displayed as an automatic hit screen on the CRT display corresponding to the selected CRT display number. Also, this electronic computer 1

Next, the operation of the above configuration will be explained. For example, if an abnormal water level drop phenomenon in the reactor occurs in nuclear power generation plan i~, first the abnormality type number is selected, and then the corresponding image number and CRT display number are selected. Here, if the abnormality type number is No. 3, for example,
The corresponding image numbers and CRT display numbers are Nα4 and N0#1 as shown in FIG. Therefore, the automatic hit screen with the corresponding image number NQ4 that aggregates information regarding the reactor water level will be displayed on the CR7 display 3a corresponding to the CRT display number Nα#1. At the same time, an automatic hit status display lamp 4a provided near, for example, above the CR7 display 3a is lit, and the CR7 display 3a is turned on.
