Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a plant monitoring device that displays the operating status of two plants in a nuclear power plant on a color C and FIT display device.

[Technical background of the invention and its problems] In general, plant monitoring devices express the status and process quantities of one power plant pictorially using digital numbers, bar graphs, single curves, etc., and collectively display them on a color CRT. The information is displayed on the screen and used effectively for plant monitoring operations. Also,
In the central operation room (hereinafter abbreviated as central operation), various important process data, alarms, etc. are collected on the control panel, so that the status of the entire plant can be understood.

However, if a worker wants to know what is going on at the site, such as when an abnormality occurs, it is necessary for the worker to actually go to the site and check the situation. In addition, regular patrols are carried out to check the status of equipment at each site, as well as the values of recorders and sorters. In the case of nuclear power plants, most of these operations are performed in controlled areas with high radioactivity levels, resulting in increased exposure for each worker. Also.

Entering and exiting these areas requires many procedures such as certain procedures and changing clothes, which requires a great deal of effort and time.

Currently, industrial televisions (hereinafter referred to as ITVs) are installed in several locations.
(abbreviated as ), so that they can monitor the situation at the site from the middle of the day, but their number is small. In addition, there is no relationship with the process computer system that is the main body of monitoring and control, so monitoring is not effective.

In view of these points, a method has been proposed in which both sides of the ITV image and the process computer are selectively displayed, and a method in which both images are combined and displayed on a single CRT monitor. In particular, the latter has the advantage of being able to simultaneously view the actual image of each device and the process amount of the plant to be monitored using the ITV.

However, even with this method, the sound of each device and the environment (temperature, radiation level, etc.) cannot be determined, making it insufficient for grasping the actual situation at the site. Furthermore, in the case of an emergency such as the occurrence of an event in a plant, the operator selects the on-site ITV to be viewed, making it time-consuming to perform the first selection operation to determine what to display.

[Object of the invention] ゝ The present invention can be used in the field, output 1. T! = aga■misao. The purpose is to provide a plant monitoring device that allows you to clearly monitor and monitor the situation at the site without leaving your home.

[Summary of the invention] The present invention includes a microphone and a temperature sensor for ITV equipment.

By adding sensors such as radiation monitors, it is possible to simultaneously output the status of the site environment around the ITV to the center, and
A system characterized in that when an event occurs in a plant, a video that is a combination of a predetermined ITV selection at the site and a CRT screen of a related process computer is automatically displayed in accordance with the event, as well as process data. It is.

[Embodiments of the Invention] Examples of the present invention will be described with reference to FIG. ITV cameras 2 are placed at key points in each part of the plant.

IT on the ITV operation panel 5 with zoom and angle in the middle
It can be freely adjusted using the V-zoom and angle adjustment stick 10. The ITV 2 has a microphone 3 that collects sounds around the ITV, and is connected to an ITV switching control device 4 that selects the ITV.

The image of which ITV camera 2 is to be displayed on the CRT monitor 7 is determined by the selection from the ITV selection panel 9 on the ITV operation panel 5 or the selection output from the process computer 23. The selection signal of the ITV selection panel 9 is IT
The selected output of the process computer 23 is transmitted via the V control device 8 to the ITV switching control device M4 via the switching input/output device 111.

The sound signal of the selected ITV camera 2 is output to the speaker 6 connected to the ITV switching control device 4, and the image signal is output to the video synthesis device [1] connected to the ITV switching control device 4.
12, and here the screen output of the process computer 23, that is, the CRT control device 2, is displayed as six images on the connected CRT monitors 7, 25.
Output to. The CRT monitors 7 and 25 are arranged not only on the ITv operation panel 5 but also on the central control panel 30, and can perform conventional graphic CRT display.

Sensors 21 that measure plant process data are installed in each part of the plant, and their signals are sent to a process input device 22.
The data is input to the process computer 23 in a form that can be processed by the computer. The process computer 23 is connected to the ITV switching input/output device 11 and the CRT control device! 24 is connected, the ITV switching input/output device 11 is connected to the ITV switching input/output device 11 to determine and select one TV in the optimal location for monitoring the plant status determined from the process data, and to send predetermined zoom conditions, camera angle signals, and selection signals to the ITV switching input/output device 11. Switching control device 14

The number of the ITV selected at the site is input via the ITV switching input/output device 11, and predetermined process data corresponding to the ITV number is displayed and output.
Data is output to the RT control device 24.

Next, the operation of the embodiment described above will be explained using FIG. 1 and FIG. 2.
The explanation will be given using an example of ``tor''.

In FIG. 2, an image 41 shows that the ITV camera 2 is

converts process data related to D/G to process computer 2.
Example 1 of the screen displayed by 3 Screen 43 is a video composite device for both!
! In this example, 12 images are combined into one image.

If the operator wants to see the D/G site, he selects the D/G using the ITV selection panel 9 on the ITV operation panel 5. The selection signal passes through the ITV control device 8 and
The image and audio signals from the ITV 2 and the microphone 3 installed in the D/G are transmitted to the switching control device 4, where the image and audio signals are transmitted to the video synthesis device 12. transmitted to speaker 6 D

The switching input/output device 11 indicates that the D/G site has been selected.
is inputted to the process computer 23 through. The process computer 23 sends a screen of predetermined D/G-related process data corresponding to D/G to the video synthesis device 12 via the CRT control device 24.

The video synthesis device 12 combines an image 41 and a screen 42 from the ITV 2.
The five screens 43 are outputted to the CRT monitor 7.25.

Here, the current D/G image is output as is to the image 43, and, for example, the value of the meter on the field panel and the lighting status of the lamp are displayed moment by moment. Further, process data related to D/GLQ, such as generator output V, A, etc., are inputted by the sensor 21, and the values are updated by the process computer 23 at intervals, and the display of the image 43 is also updated. In addition, the sound of the D/G site can also be heard from the speaker 6.

In this way, it becomes possible to actually understand the state of the site using images, process measurement data, and sound, and the center operator can obtain a realistic feeling of the plant site, improving monitoring performance.

In addition to the method of selecting an arbitrary ITV 2 by the operator as described above, it is also possible to automatically select the ITV 2 by the process computer 23. For example, when a power loss accident occurs at a power plant, the D/G automatically starts operating and supplies power to the plant, but in this way, the process computer 23 determines the occurrence of a power loss based on process data. o1cm
The ITV2 selection of the field is switched through the input/output device 11.
It is also possible to instruct the TV switching control device 4.

5. It is also conceivable to have the process computer 23 perform temporal scheduling of ITV selection.

This allows the operator to monitor a set of TV images and process data at the designated time without having to make selections one by one.

In this case, for example, as shown in FIG.
By connecting an image recording device 13 such as a VTR (video tape recorder) or an optical disk device to the system and interlocking recording, image recording of plant operation becomes possible.

Furthermore, in addition to the microphone 3, sensors for measuring the site environment such as a temperature sensor and a radioactivity monitor may be added to the ITV2, thereby allowing the central operation center to grasp more process conditions at the site. It becomes like this.

[Effects of the Invention] As described above, according to the present invention, the ITV image and the display of related process data are combined, and the on-site acoustics, environmental data, etc. are displayed and output to the central operation center. Therefore, it becomes possible to operate the plant while checking the status of equipment at the site, improving the sense of reality and monitoring performance. In particular, there are many places where radioactivity levels are extremely high depending on the location, such as nuclear power plants.2 The present invention can be used to monitor areas such as nuclear power plants.

The condition can be easily grasped without exposing workers, contributing to reducing the exposure of workers. Also.

By determining the process status and displaying the optimal images and process data, it is possible to grasp the status of the plant using conventional I
This is a dramatic improvement over the case of using only TV or process data, and it also contributes to safe operation of the plant and a reduction in the burden on operators.
