Detailed Description of the Invention [Object of the Invention] (Industrial Application Field) The present invention relates to a plant operation monitoring device used for monitoring the operating status of plants such as nuclear power plants, thermal power plants, chemical plants, etc. Regarding.

(Prior Art) In recent years, in process plants that have a large number of equipment, such as nuclear power plants, thermal power plants, and chemical plants, computer technology has been utilized to improve the monitoring performance of the plant operating status.
Plant operation monitoring devices that display the response of process quantities on a display device such as a Ray Tube (Ray Tube) are being actively employed as a means of providing operation information.

FIG. 3 shows the configuration of an example of such a conventional plant operation monitoring device. The plant operation monitoring device is provided with a process input device 1 for inputting plant data such as plant parameters. A plant data signal 2 is output from the process input device 1 .

This plant data signal 2 is input to the input processing section 3, where it is processed into an easy-to-handle form by unit conversion, etc.
It is output as a plant data processing signal 4 and stored in the plant database 5 as plant data.

Then, when the operator a selects a screen to be displayed using the screen selection device 6, a screen selection signal 7 is output from the screen selection device 6, and the screen display section 8 to which this screen selection signal 7 has been input selects the screen. The display information 10 for displaying the selected screen is read from the display information data table 9 that stores display information necessary for display, while the plant parameters to be displayed are recognized from the display information 10 and the plant database 5 The plant data 11 is read from , and a screen display signal 12 is output as an image signal. The screen display signal 12 is input to a display device 13 such as a CRT, and information regarding the operating state of the plant is displayed on the screen of the display device 13 and provided to the operator a.

The input processing section 3, the plant database 5, the screen display section 8, and the display information data table 9 are connected to the computer 1.
It is housed within 4.

In addition, when it becomes necessary to operate plant equipment 15 such as valves and pumps while monitoring the plant operation status using the plant operation monitoring device configured as described above, operator a 16, and the operating state of the plant equipment 15 is changed by the operation signal 17 issued therefrom. In this case, in order to monitor plant parameters such as pressure, flow rate, temperature, etc. related to the plant equipment 15, It is necessary to select a screen containing such information using the screen selection device 6 and display it on the screen display device 13.

(Problems to be Solved by the Invention) As described above, in conventional plant operation monitoring devices, when an operator attempts to operate plant equipment using an operating device, the pressure, flow rate, temperature, etc. related to the plant equipment are monitored. In order to monitor plant parameters, it is necessary to select in advance a screen containing such information using a screen selection device and display it on a screen display device.

Therefore, operators must select screens to obtain the necessary plant parameters every time they operate equipment, and the required information may be spread over multiple screen displays, which increases the burden on operators. The problem is that there are too many. Such a burden on the operator leads to increased mental fatigue of the operator, which increases the possibility of erroneous operation, especially in a chaotic state such as when a plant abnormality occurs.

Furthermore, this is especially the case when the screen display device is not in the immediate vicinity of the operating device, since it is difficult to monitor while operating the device.

The present invention was made in response to such conventional circumstances, and eliminates the need for screen selection when operating equipment, reducing the burden on the operator compared to the past, reducing the possibility of erroneous operation, The present invention aims to provide a plant operation monitoring device that can improve plant safety.

The plant operation monitoring device of this embodiment is provided with a specific equipment determining section 18, and a coordinate input device 19 (for example, a mouse) is connected to this specific equipment determining section 18. Then, when the operator a inputs the coordinate signal 2o corresponding to the plant equipment on the display screen of the screen display device 13A using the coordinate input device 19, the specific equipment determination unit 18 compares it with the display information data table 9 and selects the plant equipment. The system is configured to specify the selected plant equipment (selected equipment) and send it as an equipment selection signal 21 to the equipment information display section 22.

In addition, the equipment information display section 22 includes, as information to be displayed for each plant equipment, information about displays (operation displays) necessary to operate these plant equipment and information necessary for monitoring during operation. A device information data table 23 containing information on various parameters is connected. Then, the device information display unit 22 reads data regarding the selected device described above from the device information data table 23 in accordance with the device selection signal 21, and has a multi-window function as an operating device window 24, for example, as shown in FIG. The screen display signal 1 is displayed so as to be superimposed near the selected device (plant device 15) on the screen display device 13A.

4a desired display area (for example, "off" in Fig. 2)
, "person", etc.) is selected using the coordinate input device 19,
The device operation coordinate signal 26 corresponding to this position is input to the device operation determination section 27. Then, the equipment sweeping determination unit 27 uses the equipment operation coordinate signal 26 and the equipment information data table 23.
It is determined what kind of operation has been performed, such as starting or stopping the device, by comparing the information with the device, and sends the device operation request signal 28 to the operation signal output section 29. The operation signal output unit 29 sends an operation signal 17A to the plant equipment 15 in accordance with the equipment operation request signal 28 to change the state of the plant equipment 15.

That is, in the plant operation monitoring device of this embodiment, the operation status of the plant is displayed on the screen display device 13A, and when it becomes necessary to operate the plant equipment during monitoring, the operation status of the plant is displayed on the screen display device 13A. The displayed plant equipment 15 to be operated is selected on the screen using a coordinate input device 19 such as a mouse. Then, an operation window 24 consisting of an operation display 24a for operating the selected device and a parameter display 24b that needs to be monitored during operation is automatically displayed near the selected device 15 on the same screen. Operation and monitoring can be performed simultaneously on the screen.
