Abstract

PURPOSE:To display a system picture including more detailed and appropriate information on a CRT, by fitting a coordinate input device to the CRT and monitoring the state of a plant through a summary picture during normal operations and, as occassion demands, specifying a simbol in the summary picture. CONSTITUTION:When an operator wants to see a system picture including detailed information, he touches the system part he wants to see, namely, its simbol in the summary picture with hand. Then an analog signal is transmitted from a touch screen 11 to a detector 13 through a cable 12. The detector 13 finds the X and Y coordinates of the touched point in accordance with the analog signal and transmits the coordinates to a process computer 3 through another cable 14. The process computer 3 determines the picture number corresponding to the X and Y coordinates and actuates a picture producing program. Then the computer 3 inputs the plant data to be displayed in the picture from data files and produces the designated picture, and then, displays the picture on the CRT 6 of a control board 5 through a cable 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a plant monitoring device that displays information on the operating status of a plant.

[Technical background of the invention and its problems] Plant monitoring devices are used to monitor the operating status of plants.

A conventional plant monitoring device will be explained with reference to FIG.

In the figure, the state quantities of the plant are measured by detector 1, and the data measured via cable 2 is transmitted to the process.
It is input to the computer 3. The output information of the process computer 3 is displayed on a CRT 6 attached to the control panel 5 via a cable 4 as a system diagram as shown in FIG. 5, for example, by selecting the screen with the request key 7. After the output of the detector 1 inputted to the process computer 3, that is, the blunt state falsehood is inputted to the input 3a,
stored in the plant data file 31).

On the other hand, when the operator presses a request key 7 such as a numeric keypad 7' one-button button 7 as shown in FIG. 6, a screen is selected (process 3e). Information on which screen is to be output is input to the wrestling input device 9 via cable 8, and further input to the process computer 3 via cable 10. Based on that information, the screen is selected and the screen creation program is output. ) (Process 3c), create and output the specified screen by inputting from the plan 1 to data file displayed on the screen Process 3d), control the CRT 6 in the 12TL board 5 via the cable 4, for example, as shown in Figure 5. It is displayed as a system diagram as shown in .

Since the conventional plan 1 monitoring device is configured as described above, the operator has to search for the system screen containing the information he/she wants to know by selecting it using the numeric keypad or one-button button. There were problems such as the burden of 4R being ecstatic, the possibility of overlooking the occurrence of small abnormalities, and a delay in the detection of abnormalities.

[Object of the Invention] The present invention has been made in view of the above circumstances, and its purpose is to monitor the overall status of the plant on a summary-level screen during normal operation, and to monitor the overall status of the plant in an emergency or when necessary. The object of the present invention is to provide a plant monitoring device that provides detailed and appropriate information to the plant.

[Summary of the Invention 1] In order to achieve the above object, the present invention provides a plant monitoring device that embeds data detected from each part of a plant using a predetermined program and displays the processing results on a CRT. , a coordinate input device is attached to the CRT, and while the plant status is monitored on the summary screen during normal operation, symbols on the summary screen can be specified in emergencies or when necessary.This allows for more detailed and appropriate information. The screen containing the system can be displayed on the CRT.

[Embodiments of the invention] An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention. In comparison with the plant monitoring device shown in FIG. 4, FIG. 1 shows a coordinate input device provided on a CRT, for example, a touch screen 11, a detection device 13 that detects the position of a touched place based on a signal from the touch screen 11, and a coordinate input device provided on a CRT. Means (3'') for determining the screen number of the display screen from the position of the screen and the cable 12 therebetween.
The only difference is the configuration with the addition of 44, and the configuration of 1 is the same as the configuration of the plant monitoring device shown in Fig. 4, so the same components are given the same reference numerals and detailed explanations will be given. It shall be omitted.

In FIG. 1, a detector 1 measures the state quantity of plan i-, and the measured data is input to a process computer 3 via a cable 2. In FIG.

The output information of the process computer 3 is displayed as a system diagram as shown in FIG. 5, for example, by selecting both sides of the request key 7 on the CRTG installed in the control panel 5 via the cable 4.

The output of the detector 1, that is, the plant state quantity inputted to the process computer 3 is input processed 3a and then stored in the plan i-data file 3b.

On the other hand, when the operator presses the refresh key 7 on the numeric keypad, one-button button, etc., a screen is selected (process 3e). Information about which screen is to be output is input to the process input device 9 via cable 8, and then input to the process computer 3 via cable 10. Based on this information, the screen is selected and the screen creation program is started (processing is performed). 3C), input from the plant data file displayed on the screen, create and output the specified screen 3d), use the cable 4 to connect the CRT 6 in the control panel 5 to the system shown in Figure 2, for example. Displayed as a diagram. The operator monitors the overall status of the plant using the summary screen shown in FIG.

Now, when an operator wants to see a system screen containing more detailed information, he touches the desired system part, or symbol, on the summary screen. This touch causes an analog signal to be transmitted from the touch screen 11 to the detector 13 via the cable 12. The detector 13 uses this signal to determine the X and Y coordinates of the touched location and transmits them to the process computer 3 via the cable 14. process computer 3
, the screen number corresponding to the X, Y coordinates is determined using the coordinate screen number table shown in FIG. 3 (process 3f), and the screen creation program is started (process 1'I! 3c) The plant data to be displayed on the % screen is input from the data file, and the instructed screen is created and outputted. 3d) The data is displayed on the CRT 6 of the control panel 5 via the cable 4.

[Effects of the Invention] As explained above, according to the present invention, the operation H
There is no need to search when selecting a screen, and while grasping the general status of the plant, you can view more detailed and appropriate information in emergencies or when necessary by simply identifying the coordinate input device placed in front of the CRT. Therefore, an excellent effect can be achieved in that the labor of the operator can be reduced.
