Abstract

PURPOSE:To quickly judge the abnormality of a plant by comparing plant data with the plant model stored in a storage device and decide the type of a display picture by an arithmetic processing device to display it on a display screen device. CONSTITUTION:Plant data from a plant is fetched into an arithmetic processing device 1 through a plant data fetching device 5. Display contents determining processing 11, display contents extracting processing 12, and picture generating processing 13 are executed in the device 1. Plant data is compared with plant model data 21 stored in a storage device 2. For example, if the temperature of supply water rises because of the abnormality of a supply water heater to reduce the furnace output, plant output reduction is selected by classification related to the furnace output. Next, the abnormality of the supply water system is selected by extraction of plant data (rise of the supply water temperature), and the abnormality of the supply water heater is decided by extraction of detailed plant data. As the result, required data is extracted by the processing 12 and is processed by the processing 13 and is outputted to a display screen device 3.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an operation monitoring panel for thermal power and yK subsidiary power plants.
especially. It relates to display screen devices such as CRTs and large display devices.

[Conventional technology]

Conventional display screen devices include fixed display screen devices using CRTs. In this method, the screen format to be displayed is fixed, and the parameters on the screen (for example, water pressure,
pressure indicators) and equipment operating status (e.g. pumps, etc.)
Valve etc. condition 1r! 4) was displayed in response to changes in plant processes.

[Problem to be solved by the invention]

FIG. 4 shows a conventional double-sided display device according to an embodiment. Using the screen selection screen 2, the operator selects a necessary screen according to the plant operating state, and then via the screen selection section 6b,
Select the required format from the screen menu section 3C and output it to the selection screen format section 3d. The parameters of the plant and the operating status of the equipment are part of the screen that has been selected by the signal processing unit 3a.

These conventional methods require double-sided selection operations for operators to obtain information in response to rapid changes in plant conditions, and require plant operators to perform the necessary plant operation operations. It prevents you from taking enough time to reflect and check. In addition, because the information that should be viewed in response to an event is not gathered together, there is a possibility that the operator may make a wrong decision while checking the facts.

[Means to solve the problem]

In order to achieve the above object, the present invention prepares plant model data in a storage device in order to analyze plant data and abstract the state of the plant. This plant model data is pattern-matched with plant data to abstract the state of the operating plant, and based on the results, the display screen data stored in the storage device can be selected to display a display that corresponds to the plant state. This is how it was done.

[Effect]

The plant model data is obtained by hierarchically classifying plant states. Using the plant data imported from the plant data import device, we check whether each hierarchically classified plant state is established or not, starting with the higher-level state (broad classification) and checking for more detailed classification. It is extracted and displayed from the display screen data corresponding to the plant state established for the most detailed classification. As a result, a display screen corresponding to the plant state is displayed, so the plant operator does not need to select a display screen according to the plant state. Furthermore, when a different display screen is required, the display screen can be changed based on the hierarchical classification of the plant operating status, so plant operators can easily switch the display screen.

〔Example〕

An embodiment of the present invention will be explained below with reference to FIG. In the figure, the arithmetic processing device 1 executes display content determination processing 11, display content extraction processing 12, and image generation processing 13. Reference numeral 2 denotes a storage device, which includes plant model data 21, display element data 22, and display screen data 23. 3 is a display screen device, 4 is a terminal input device, and 5 is a plant data acquisition device. FIG. 2 is an example of hierarchical classification of plant states described in plant model data.

Each node of the classification tree corresponds to a classified plant state. For each plant state, conditions for establishing the plant state as shown in FIG. 3 are described.

In the classification book shown in Figure 2, if a certain node in the tree is true, either only one of its child nodes is true, or there are no nodes that are true (r classification no. properties). Furthermore, in order for a certain node to hold true, at least that visual node must hold true. (
nature of “hierarchy”).

Using these properties, we can determine which node of the classification tree in Figure 2 corresponds to the current operating state by referring to the plant data imported from the plant data importing device to obtain the data necessary for classification. The processing procedure to be determined (such as the work content determination process in FIG. 1) is shown in FIG.

This procedure reads and examines the establishment conditions of established child nodes from the plant data one after another, and if there is a established child node, then further examines each establishment condition of that child node, and then enters the classification tree. The node that is established at the deepest level is identified as the current plant state. Once the plant condition is identified, the type of display screen corresponding to the plant condition is retrieved from the display screen data. FIG. 5 shows the types of display screens corresponding to the hierarchical classification of plant conditions shown in FIG. 2, and the layout of the display screen corresponding to the plant conditions is prepared in advance.

For example, if the feed water temperature rises due to an abnormality in the feed water heater,
Taking the case where the furnace output has decreased as an example, LA (plant output decrease) is first selected from the classification related to the furnace output in the plant status classification book shown in FIG. Next, by extracting macroscopic plant data regarding the abnormal location (high water supply temperature), it is selected as an abnormality regarding the water supply system, and node 2BA is selected. Further, by extracting detailed plant data, it is determined that there is an abnormality regarding the feed water heater, and node 3AAA is established.

As a result, the display screen corresponding to the node 3BAA is selected, and the necessary data is extracted from the plant data by the display content extraction process 12 in FIG. 1, and processed by the image processing device using the display element data and the plant data. (processing in Figure 13) and output to the display screen device 3. The operator can immediately confirm an abnormality by looking at the screen related to node 3AAA in the plant operating state, that is, the display screen around the feed water heater, as the initial screen. If necessary, the display screen corresponding to plant state 2AA can be created by tracing the upper established nodes of the classification tree.
While the screen corresponding to the plant state IB can be obtained by inputting from the terminal input device, it is also possible to view other display screens (for example, LA) on the same hierarchy.

This kind of hierarchical display corresponding to the plant status allows plant operators to clearly see the status that should be looked at in detail.
You can easily know its position within the entire plant.

〔Effect of the invention〕

According to the present invention, plant operators can first obtain a display screen that presents the most characteristic information in the current plant state, so they can make quick and accurate decisions in the event of a plant abnormality. can do.

In addition, the display screen configuration based on hierarchical classification allows
You can smoothly see the status of the plant from part to whole, and from whole to part.
