Abstract

PURPOSE:To grasp immediately an abnormal state of a plant by providing an alarm function on a pilot lamp, etc. of a CRT request button corresponding to a CRT picture screen on which an abnormal parameter is displayed. CONSTITUTION:A plant abnormality alarm device inputs 2 periodically a process data of a plant 1, and monitors by a monitor device 3 whether each parameter is normal or not. As a result, when an abnormality is detected, an alarm generating signal 4 is sent out, and an alarm is informed by a pilot lamp 6, etc. through an alarm output device 5. In this regard, this device is provided with plural CRTs 9 connected to a CRT output device 7, and a control board 8 having plural CRT request buttons 10. In this case, an alarm checking device 11 is provided, which parameter is abnormal is checked by receiving a signal from the monitor device 3 by said device 11, also the CRT9 picture screen is selected and said button 10 corresponding to it is turned on or flickered, etc., and an alarm and information of an abnormal parameter are offered to a user.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a plant abnormality warning device, and particularly to an abnormality warning device in a plant monitoring system using a CRT screen.

[Prior art]

The configuration of a conventional device of this type is shown in FIG. In this figure, (1) is a plant such as a nuclear power plant, (2)
) periodically manually inputs the process data of the above plant,
(3) is an input device that processes data into a form that is easy to process for plant monitoring and information provision on a CRT; (3) is a monitoring device that monitors whether each of the above plant parameters is normal; .

Alarm generation signal (4) when an abnormality in the plant is detected
Send out. +51 is an alarm output device that generates an alarm upon receiving the above-mentioned alarm generation signal, and (6) is an alarm device such as a speaker or indicator light as a means for notifying the alarm.

In the case of a speaker, it emits a sound (in the case of an indicator light 11, it lights up or flickers.In addition, (7) receives a signal from the monitoring device (3) and displays the monitoring results on a CRT screen. A CRT output device that performs display processing.

(8) is a control panel that displays multiple CRTs (9AX9B) connected to the CRT output device and multiple CRTIJ quest buttons (9AX9B) for selecting the screens of these CRTs.
IOA) to (10F).

Conventional equipment is configured in one or more ways, so if an abnormality occurs in the plant, the user can immediately know about it, but what kind of abnormality has occurred can be determined from the control panel (8). When an abnormality occurs, the user must check the plant data displayed on the CR1 screen installed on the CR1 screen, and an immediate and appropriate response is required. However, it takes time to discover abnormal parameters. There was a drawback. or.

It also has the disadvantage that it is easy to overlook when multiple parameters are abnormal.

[Summary of the invention]

This invention was made in order to eliminate the above-mentioned drawbacks, and the C! The present invention is characterized in that the RTIJ quest button or the indicator light, indicator, etc. corresponding to the abnormal parameter has an alarm function. An example will be explained. In this figure, aυ is an alarm checking device which receives a signal from the monitoring device ii+31 and checks which parameter is abnormal.

Check which CR1 screen the abnormal parameter is displayed on, select the appropriate CR1 screen, and display a warning and abnormal parameter information to the user by lighting or flickering the corresponding CRT request button. It provides:

The rest of the configuration is the same as that of the conventional device shown in FIG. 2, so a description thereof will be omitted. In addition, as another embodiment, a similar effect can be expected by operating an indicator corresponding to an abnormal parameter or by lighting or flickering an indicator light corresponding to an abnormal parameter.

〔Effect of the invention〕

This invention is configured as described above.

In addition to being able to immediately grasp abnormal situations in the plant,
Even when a plurality of parameters are abnormal, it is possible to reliably grasp the alarm status on a separate screen of the CRT without overlooking it.

[Brief explanation of drawings]

FIG. 1 is a schematic configuration diagram showing an embodiment of the present invention. Figure 2 is a schematic configuration diagram showing a conventional device.In the figure, (
1) is the plan), (21 is the input device, (3j is the monitoring device, (5) is the alarm output device, (6) is the alarm device, (7
1 ORT output device, (8) light control panel, (9AX9B
) is a CRT, (10A) to (10F) are CRT request buttons, and nu is an alarm check device. Note that the same reference numerals indicate corresponding parts. Agent: Yu Oiwamasu (and 2 others)

Claims (1)

[Claims] (1) In a system that monitors the presence or absence of plant abnormalities, displays the results on multiple CRTs, and allows selection of CRT screens using the CRT request button, the CRT on which plant abnormalities are displayed is 1. A plant abnormality warning device characterized by lighting or flickering a CRT request button or an indicator light, an indicator, etc. corresponding to an abnormality parameter. 12) The plant abnormality warning device according to claim 1, wherein the plurality of CRTs and CRT request buttons are mounted on a control panel.
