Abstract

PURPOSE:To enable all operators to accurately grasp the present state of a plant by providing a large-sized display device to display the information so far displayed on plural units of CRT in order to grasp the overall state of the plant. CONSTITUTION:A large screen 4 is connected to a control computer system 11 via a cable 12 and a large screen driver 10. In the same way, a CRT 5 set on a general monitor control board 1 is connected to the system 11. Thus it is possible to select the contents optimum to the screen 4 out of the system 11 in response to the operating state of a plant and to display them. Then the contents so far displayed on plural CRT can be displayed on a single screen by means of the screen 4. As a result, all operators can easily and simultaneously grasp and decide the present state of the plant through a central control room.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a central control device for centrally monitoring and controlling a large-scale plant, and is particularly applicable to systems in which a large number of operators share responsibility for monitoring and controlling one plant. The present invention relates to a central control device suitable for.

[Conventional technology]

For example, Hitachi Review Vol. 1.62. &9 (September 1980), harmonizes the aggregation of plant information with the automation of operations, as well as operation guidance and diagnosis.

A central control unit equipped with functions such as prediction was used. And this control device has a color C of about 20 inches.
RT display and audio notification systems are adopted, and one CR is used for the purpose of grasping the status of the entire plant.
Since T is insufficient, a method is used in which information is divided and displayed on several CRTs.

In addition, as another example, in control rooms of water and sewage systems, power transmission and distribution systems, etc., graphic panels and mosaics are used to display the entire plant.

[Problem that the invention seeks to solve]

In the conventional device using the above CRT display, one CRT
Therefore, it is difficult for all operators in the central control room to grasp the entire current state of the plant at the same time, and each operator can monitor each subsystem in the plant. There is a problem in that when trying to control the system in an optimal state from an overall perspective, it takes time to judge the situation, and there is a possibility that the response may be delayed, especially in the event of an abnormality. In addition, graphic panels and mosaic panels allow all operators to monitor the entire system, but the disadvantage of these is that the displayed figures are almost fixed and the displayed information cannot be dynamically changed according to the plant status. be.

An object of the present invention is to provide a central control device that allows all operators in the central control room to simultaneously and accurately grasp the current state of the plant according to its operating status.

[Means for solving problems]

The above purpose is to install a large display device that can display any image, and to display information that was previously divided and displayed on several CRTs in order to understand the status of the entire plant on this large display device. This is achieved by having a configuration that allows

[Effect]

As with the conventional CRT, the information displayed on this large display device is selected by a computer system in accordance with the operating status of the plant. This allows all operators to comprehensively grasp and judge the plant status quickly and accurately. In addition, by adding the necessary processing to plant information and displaying it effectively, it is possible to assist operators in making comprehensive decisions, and each operator can control each subsystem in an optimal state from the perspective of the entire plant. It becomes like this.

〔Example〕

Embodiments of the present invention will be described below with reference to FIG.

FIG. 1 shows an example of a central control room equipped with a central control device according to the present invention. A large display device with three large screens 4 behind the general monitoring control panel 1 equipped with operating devices 6, etc.! 2 is placed and easy to operate.

Efforts are being made to improve monitoring performance. However, the large display device 2 may be placed in any position other than the rear as long as it improves operability and monitoring performance, and various layout plans for the central control room can be considered.

FIG. 2 shows an example of a system configuration of a large display device, which is a feature of the present invention. The large screen 4 is connected to a control computer system 11 by a cable 12 through a large screen drive device 10 . Further, the CRT 5 on the general monitoring control panel 1 is similarly connected to the control computer system 11. With such a system configuration, it becomes possible to select and display optimal content on the large screen 4 from the control computer system 11 according to the operating state of the plant.

Furthermore, Figures 3 to 5 show examples of nuclear power plants in which the necessary processing is added to the plant information and the information is displayed effectively. Figure 3 shows the operating status of the entire nuclear power plant.
This is an example of a screen (plant summary display), and such a screen allows operators to easily understand the operating status of the plant. Figure 4 is an example showing the transition of major parameters during a plant abnormality (analog trend display), Figure 5 is an example showing the operating status of the engineering safety equipment system (ECCS summary display), and plant abnormality. Sometimes, by switching to a screen like this, it is possible to allow operators to easily determine the current state of the plant, and to ensure that each operator's subsequent operations are appropriate. It becomes possible.

In addition, by using a large screen, the displayed content, which was previously divided between several CRTs, can be displayed on one screen, reducing the time required for operators to understand the plant status. .

Conversely, it is now possible to display the status of each part superimposed on the stitching screen, making it possible to display the whole and the details of each part at the same time. Furthermore, it is possible to display information on an industrial television, so that in the event of a plant abnormality, all operators can immediately recognize the details of the abnormality.

According to this embodiment, there is an effect that all the operators can easily grasp the current plant status at the same time.

〔Effect of the invention〕

According to the present invention, all operators in the central control room can easily and simultaneously grasp and judge the current plant status.
Each operator will be able to control each subsystem in an optimal state from the viewpoint of the entire plant, resulting in improved operability, monitoring performance, and controllability.
