Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for monitoring the operating status of a plant, which displays all eight types of information on a dialog terminal device that interacts with an operator. This invention relates to a plant operation monitoring device that has been improved so that it can perform monitoring tasks without referring to other document data or other CRT displays.

(Prior Art) Japanese Patent Laid-Open No. 60-36'l14 is known as the latest technology regarding a plant operation monitoring device.

The plant operation monitoring device according to the above-mentioned known technology is (a)
an input device that inputs signals from the plant; (b) a diagnostic processing device that receives signals from the plant and generates operation permission signals for each device; and (c) an input device that receives the signals from the plant and generates operation permission signals and operation signals. (d) an output display device that responds to the operator when the operation is not permitted;
e) It is equipped with a database recording device and a database editing device, and according to this known technology, it is possible to prevent the operator from erroneous operation, and when the operation is not permitted, the operator is informed of the reason. obtain.

[Problem to be solved by the invention]

In order to maximize the effectiveness of the above-mentioned known technology, it is necessary to make a comprehensive judgment by referring to various drawings, charts, and images showing the current state of the equipment in addition to the display on the CRT, which is a means of interaction. Must be.

For this reason, it is necessary to take out and refer to drawings, etc., or call up images other than the CRT used for interaction, which places a heavy physical and mental burden on the operator. Since it takes time, there is a problem that the response when an emergency situation occurs is delayed.

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a plant operation monitoring device that can automatically display all reference data necessary for operation monitoring using a dialogue terminal device.

[Means to solve the problem]

When a plant operation monitoring device according to a known example is used to perform plant operation monitoring work, data that needs to be referenced can be broadly classified into (i) design data and (ii) current data.

(i) Design data refers to data that does not change easily unless the relevant plant equipment is modified, such as piping system diagrams, equipment drawings, equipment layout diagrams, control sequence diagrams, instruction manuals, etc. be.

(ii) @-shaped data refers to data that can change from moment to moment, such as images of equipment captured by an ITV camera.

The above purpose is to provide a drawing information storage device that stores design data and an image information storage device that stores current data, and to monitor the operation monitoring device based on the information data given from the target functional system. This is achieved by providing a function to search and determine the corresponding information, and the image or document information obtained as a result, to combine and display the information of the target function, and to provide an interaction device for interacting with the operator.

[Effect]

The two types of reference data are each stored as information (ie, video information) in a form that can be displayed on a CRT using the apparatus configured as described above.

Optimum information is determined and selected from the video information based on information given from the function targeted by the driving monitoring device. By displaying the target function information and the selected video information in contrast on the same screen on the interaction device with the operator, the operator can Since decisions can be made using all necessary information, decisions regarding the operation monitoring plan can be made efficiently, quickly, and accurately, and there will be no erroneous decisions.

〔Example〕

FIG. 1 is an explanatory diagram showing one embodiment in which the present invention is applied to a power generation plant.

Equipment/equipment 1, which is a component in a power generation plant, is
It is controlled by a control device 2. or.

Plant status data from the control device 2 is input to the computer system 5, and various information data processing is performed by the operation monitoring work of the computer system 5, and the results are 1.
It is displayed on an interaction terminal device 6 such as a display device, and operators monitor the operation of the plant.

In this embodiment, in a plant operation monitoring apparatus having such a configuration, the functions of a plant maintenance and inspection work planning system will be described in particular.

In the maintenance and inspection work planning system, when planning the maintenance and inspection work of the equipment 1, plant status data, scheduled maintenance work personnel, and maintenance time period are used.

Plans are created by comprehensively determining information such as related equipment and related maintenance plans. This planned information is provided to the driver 1 via the dialog terminal device 6 by the dialog processing function. This embodiment adds the following functions to this conventional function.

In other words, the details of each part of the target equipment 1 for the maintenance and inspection work plan are provided by photographic images, image information of current data from ITV, etc., and part of image information of design data showing the equipment installation status, layout status, etc. It is provided with a storage device 5a for storing image information.

Further, it is provided with a document information storage device i5b that stores document book 4 information that is design data such as a piping system diagram 2 equipment configuration diagram of the target equipment 1, *equipment handling manual, and equipment control sequence.

Furthermore, both of the information storage bags ffi 5 a are stored based on the key information provided by the maintenance and inspection work planning system.

The corresponding information search processing function 5C, which searches which information in 5b to use, selects the information, combines this information with the information from the maintenance and inspection work function 5d, and executes the dialog processing function 5e.
The dialogue is displayed on the dialogue terminal device 6 via the dialogue terminal device 6.

FIG. 2 shows an example of a screen displayed on the dialog terminal device 6, that is, a window display or the like on the dialog display screen of a normal maintenance/inspection work plan (same as in the known example).
The image information of the design data and the video information of the current data are combined and displayed.

FIG. 3 shows an example of a method for searching and selecting information to be combined.

Based on the information given from the maintenance inspection planning system, the target information determination process uses the target information determination condition data to:
Document Information 2 Select appropriate information from image information and search and select information to be displayed.

As described above, according to this embodiment, operators can refer to everything from macro information to micro information regarding maintenance and inspection work plans by simply interacting with the dialogue terminal device, and can investigate related documents and There is no need to investigate the condition of installed instruments, etc.

Efficient, quick and accurate planning becomes possible.
