Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention is a method for monitoring plant conditions by displaying the pulse status of plants such as nuclear power plants, chemical plants, and thermal power plants on a screen. The present invention relates to a plant monitoring device for performing <2.

(Conventional technology) In recent years, in order to improve the ability to monitor the operating status of plants,
In addition, in order to downsize plant monitoring operation panels, CRT (Cathode Ray Tube), which utilizes computer technology, has been developed.
Display devices such as be) are being actively adopted as a means of providing driving information. The plant process information, which was previously recorded using recorders, is stored as plant data in the computer's internal storage device.
CRT for Plan 1 operators to monitor Plan 1
Jζ is displayed on the screen.

(Problem to be Solved by the Invention) The display on the lower moving surface of the CI can be displayed by selecting the screen on which the system or function that the driving port wants to monitor is displayed from a plurality of preset screens. ing.

However, the contents of the plant parameters displayed on those screens are fixed on that screen, and the form of their expression is also fixed.

Therefore, when the plant operation wants to know the plant parameters, if the parameters are displayed on the selected screen, or even if they are displayed, if the expression format is fixed, monitoring will be performed. Depending on the situation, the display may not always be appropriate, and may not be very desirable from an operational point of view.

The present invention has been made taking the above circumstances into consideration, and provides a plant monitoring device that can select any desired plant parameter and display it on the screen, as well as select any form of expression. The purpose is to provide services.

[Structure of the invention]

(Means for Solving the Problems) The present invention includes a blues input device for inputting plant data, an input processing section for converting the plant data signal from the process input device into a format suitable for screen display, A plant database that inputs the plant data processing signal from the human horn processing section and stores it as plant data, and a process that panorizes the plant data stored in this plant database using the planmy data input signal and displays it on the screen. a screen display control unit that performs the above operations, a screen display device that receives screen display signals from the screen display control unit and displays plant data on the screen, and detailed information on the plant data that is to be displayed on the screen display device and its representation. a display request input device for inputting a request regarding the form;
The apparatus is equipped with a display request determination section that receives a display request signal from the display request input device and outputs a display command signal to the screen display control section. .

(Operation) Plant data signals input from the plant process via the process input device are converted into a format suitable for screen display by the input processing section, and stored in the plan database. The plant data stored in the plant database is displayed on the screen display device by the screen display control section.

When a display request signal is transmitted from the display request input device, the display request determining section receives the display request signal and determines the content of the request. If the request is a request to display detailed information on the plant pig, a display command signal is output to the screen display control section to display the detailed information on the screen. Further, when the request content is a request regarding the presentation form, a display command signal is output to the screen display control section to change the presentation form of the detailed information.

In this way, the display content and presentation form of detailed information on plant data can be changed according to the operator's request, making it easier to monitor than in the past.

(Example) An example of a plant monitoring head according to the present invention will be described with reference to the accompanying drawings.

The plant monitoring device is suitably used as a monitoring device for a nuclear power plant, and as shown in FIG. An input processing section 3 converts the signal 2 into a format suitable for screen display; a plant database 5 receives the plant data processing signal 4 from the input processing section 3 and stores it as plant data; A screen display control unit 7 inputs the plant data obtained as a blunt data input signal 6 and performs processing for screen display, and a screen display control unit 7 inputs a screen display signal 8 from the screen display control unit 7 to display the plant data on the screen. a display request input device 10 for inputting requests regarding detailed information on plant data to be displayed on the screen display device 9 and its representation form; and a display request input device 1
a display request determining section 13 that inputs a display request signal 11 from 0 and outputs a display command signal 12 to the screen display control section 7;
are provided.

Buhund input device? 1. Measures water level, pressure, temperature, etc. through various detectors installed in each process of the plant.
Flow rate etc. 11t! Periodically lean-pulling data regarding the state h and i of the device.

The input processing unit 3 inputs the state quantity of y'' sampled by the input device 1 into the plan 1.
- Input as data signal 2, convert into a format suitable for screen display, and output as plant data processed signal 4. In the plant database 5, the contents of the plant data processing signal 4 outputted from the input processing unit 3 are stored as plant data at regular intervals.
.

For example, if you want to know the details (7 information) about the equipment displayed on the plant system monitoring screen shown in Figure 2, move the mouse cursor 14 to the position where the equipment is displayed.
, and press the 71x button on the display request input device 10 to select C.

When the mouse button is pressed, a display request signal 11 is sent.
The display request determination unit 13 determines the selected device from the display request signal 11 and sends a display command signal 1 to the screen display control unit 7.
Cover the output of 2. The screen display control unit 7 displays detailed information display 15 related to the selected device on the screen of the screen display device 9, as shown in FIG. .

If it is desired to change the presentation form of the detailed information display 15, the user operates the display request input device 10 and selects the trend display selection button 16 or the barge pl-display selection button 17 on the screen. When a selection is made, a display request signal 11 is output from the display request input device 10, and a display request determining section 13 determines the content of the request and outputs a display command signal 12 to the screen display control section 7. The screen display control unit 7 changes the expression form of the detailed information display 15 corresponding to the selected button.
6, as shown in FIG. As shown in FIG. 5, the detailed information display 15 is expressed in a partial display format 19. Furthermore, when the digital display selection button 20 is selected in FIG. 4 or FIG. 5, the representation format of the detailed information display 15 becomes the digital display format 21 as shown in FIG. Detailed information display 1;
) is not limited to the one shown in FIGS. 3 and 5 (see FIG. 5), and various other formats are possible.
