Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) This invention is aimed at preventing equipment failures, malfunctions, operator errors, or external disturbances in the operation of process plants such as power plants and oil refinery plants. The present invention relates to a plant operation system that detects disturbances in a process caused by such factors and diagnoses the cause of the abnormality and the state of the plant, and a process plant man-machine dialogue device that enables good interaction between operators.

(Prior Art) If disturbances in a process plant are left unaddressed, there is a danger that material imbalance and energy concentration will occur in local parts of the plant, resulting in damage to the plant and release of harmful substances into the environment.

Therefore, it is necessary to detect this disturbance early, diagnose the state of the plant, and take appropriate measures. In a process plant, necessary information within the plant is collected in a central control room, and this information is monitored to generally detect and diagnose abnormalities within the plant.

In other words, a normal operating range is determined in advance for the measured values from the plant regarding appropriate information, and an alarm device that issues a warning to the operator when the measured value deviates from this range enables wide monitoring of the entire plant. Regarding the method of abnormality diagnosis when an alarm occurs,
The problem is being dealt with by establishing procedure manuals and providing driver training.

However, as process plants become larger and more complex, the scale of these warning devices has also grown, and procedures and training have also become more complex. The operator may not be able to take action.

Therefore, systems are being developed that utilize computer information processing technology to provide only truly valuable and appropriate information to operators.

(Problem to be solved by the invention) However, in the above-mentioned system that provides only truly valuable and appropriate information to operators, the information In many cases, the flow is unidirectional, and there are few information provision devices that connect the designer's intentions and the operator's questions in an interactive format. The development of an interface that can estimate the operator's intentions and provide the necessary information appropriately and quickly in an interactive format has been delayed.

This invention was made in consideration of the above circumstances,
Through dialogue between operators and the plant operation support system,
It is an object of the present invention to provide a man-machine interaction device for a process plant that allows operators to broadly and quickly understand the plant status and execute appropriate plant operation.

[Structure of the invention]

(Means for Solving the Problems) The present invention provides a screen selection device in which the purpose and means of a plant and a two-dimensional hierarchical structure of the whole and parts are set;
a menu determining device that determines a menu such as the type of plant system to be displayed on a screen; a dialogue end interface device that determines a screen to be displayed by integrating signals from the screen selecting device and the menu determining device; The present invention is characterized by comprising a dialogue control system that determines the appropriateness of the signal from the dialogue end interface device and causes a screen to be displayed on a display device of the plant operation support system.

(Operation) Therefore, according to the man-machine dialogue device for a process plant according to the present invention, the thought process of the operator is input using the screen selection device regarding the guide displayed on the display device of the plant operation support system, and the above-mentioned The prerequisites for the guide can be displayed on the display device. For this reason,
Since the operator's thoughts can be systematically communicated to the plant operation support system through dialogue, the operator can be made to broadly and quickly understand the plant status, and the plant can be operated appropriately.

(Example) Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a block diagram showing an embodiment of a man-machine interaction device for a process plant according to the present invention together with an operation support system.

Artificial objects such as process plants are generally constructed with a clear purpose and function. The structure of this artifact consists of a system for achieving the final goal of a process plant, subsystems that make up this system and have various subgoals to achieve the final goal, and a system that composes these subsystems and It has an auxiliary system to maintain and demonstrate its functions, and is structured in a hierarchical manner.

Therefore, for such structures as artificial objects, the first consideration is to classify them into parts of the whole.

In addition, in contrast to such a hierarchical structure based on parts of the whole, it is also possible to consider a hierarchical division based on functional aspects of the process plant. In other words, in general, the many functions performed by physical structures are hierarchical in terms of their means of realization and purpose.

This functional hierarchy is roughly divided into five layers: (1) object purpose/constraints, (2) abstraction functions, (3) generalization functions, (4) physical functions, and (5) physical shapes. It will be done.

Now, an abnormality (failure) that occurs in a physical structure affects some of the functions performed by that structure, and this effect is caused by the above-mentioned means-only purpose; This will have a ripple effect. In this way, anomaly propagation follows a bottom-up process.

On the other hand, when an operator diagnoses an abnormality, they usually use a top-down process, starting from the top of the hierarchy and gradually moving down the hierarchy as they catch up on the abnormality, narrowing the scope of the search. .

This is because for a process plant that operates with a purpose, the greatest concern is whether or not the final purpose is always achieved. The man-machine dialogue system shown in FIG. 1 connects the operator's top-down information processing process and bottom-up abnormality propagation through dialogue.

This man-machine dialogue device 1 includes a dialogue panel 2 as a screen selection device, and a CRT (Cathor+l RayTub) that specifies a display device for displaying the selected screen.
e) A selection panel 3, an interactive menu selection system 4 as a menu decision device that also determines the menu to be displayed on the screen, a menu database 5, a CRT 6 for interaction, an interaction panel 2, a CRT selection panel 3, and an interaction CRT 6; A dialogue end interface device 7 which inputs a signal from a touch sensitive screen 11 installed on the CRT 6 to determine the screen to be displayed and determines the CRT on which the screen is displayed, and a signal from the dialogue end interface device 7. The determined suitability of the CRT in the CRT group 10 of the process plant operation support system 9 is determined.
and an interaction control system 8 that displays a screen on the screen.

On the dialogue panel 2, as shown in Fig. 2, a two-dimensional hierarchical structure of the plant's objectives, means, and parts of the whole is set.
Among these, the areas used for each plant have been clearly identified through many cognitive experiments.

FIG. 2 shows an interactive panel 2 used in a nuclear power plant, and the areas used by nuclear power plant operators in the decision-making process regarding abnormalities are indicated by circles.

When the operator selects an arbitrary location (for example, 2B) on the dialogue panel 2, the dialogue end interface device 7 lights up this location to indicate that this location has been activated. The operator can check the currently lit area (2B) on the two-dimensional area of the dialogue panel 2 and the upper and lower areas (for example, IB, 3B).
) and engage in dialogue after understanding the relationship between them. In other words, if the currently lit location is the location indicated by WHAT in Figure 3, each location above and below it is WHV,
This is the HOW section. If the operator wonders why the currently selected information screen is selected, press the WHV section to select it, and if the operator wants to know how to implement it, press the HOW section to select it.

In addition, more detailed information (information that enlarges the part) in terms of a part of the whole than the currently selected information display.
If you intend to
convey one's intentions. On the other hand, if you want to zoom out and see the whole picture, press the left side (total side) to activate it.

The selection signal a of the information screen selected in this way is output from the dialog panel 2 to the dialog end interface device 7.

On the other hand, the CRT selection panel 3 specifies which CRT in the CRT group 10 is to display information.
The sections of this CRT selection panel 3 are physically set to be approximately the same as the arrangement of the CRTs in the actual CRT group 10. In other words,
As shown in Fig. 4 (A), the CRT group 10 consists of two large CRs.
When three small CRTs are spatially arranged under the T, the sections of the CRT selection panel 3 are set as shown in FIG. 4(B), the same as in FIG. 4(A). Ru. This CRT
The CRT selection signal b from the selection panel 3 is also output to the dialogue end interface device 7.

The dialog menu selection system 4 selects a menu based on the currently activated location on the dialog panel 2 (dialogue intention) and the location previously activated on the dialog panel 2 by the operator (dialogue history). From database 5 to dialogue CRT 6
The menu data to be displayed is selected and output to the dialog end interface device 7. Here, the menu database 5 stores menus such as names of plant system types, such as reactor isolation cooling system (RCIC) and high pressure core spray (HPCS). These menus are
They are grouped and stored for each location on the dialog panel 2 that should be activated. If the number of grouped menus is small, a screen image is prepared. When the number of selected menus is 9 or less, the interactive menu selection system 4 displays the menu as a screen image reduced from the text type. The reason why the selection menu is set to 9 or less is because the chunks that can be retained in human primary memory (
This is because the maximum value of the memory unit (unit of memory) is said to be 7±2.

On the screen of the dialogue CRT 6, a menu selected by the dialogue menu selection system 4 based on a signal from the dialogue end interface device 7 is displayed. Dialogue CRT6
A touch-sensitive screen 11 is installed in the
The menu specified by the operator is detected by this touch-sensitive screen 11 and output as a menu signal C to the dialog end interface device 7.

The dialogue end interface device 7 first inputs the CRT selection signal b from the CRT selection panel 3 and outputs it to the dialogue control system 8. Then, this dialogue control system 8
Via the information display system 12 of the plant operation support system 9, the information from the dialog end interface device 7 is displayed on a designated CRT of the CRT group 10.

In addition, the dialogue end inquisition device 7 inputs the selection signal a from the dialogue panel 2, inputs and integrates the menu signal C from the touch sensitive screen 11, and determines the information that the operator wants to know.

The dialog control system 8 displays the determined screen on the selected CRT of the CRT group 10 via the information display system 12.
to be displayed. For example, when an operator specifies HPCS on the dialog CRT 6 screen and selects 2B (Figure 2) on the dialog panel 2, the mass balance of water supply from the water source to the reactor is displayed abstractly. . Then, when the operator specifies 3B (FIG. 2) on the dialog panel 2, a system diagram of the HPCS is shown, and a location where the mass balance of water supply is disrupted is shown. Furthermore, if the operator selects 3C (Figure 2), HPCS components (tank, pump, nozzle, etc.)
status is displayed.

When the menu signal C is not output from the touch sensitive screen 11 to the dialogue end interface device 7 and a signal based only on the selection signal a from the dialogue panel 2 is output to the dialogue control system 8, this dialogue control system 8
outputs to the dialog interface device 7 that the decision made by the dialog interface device 7 is insufficient. Upon receiving this, the dialogue end interface device 7 outputs a signal to the dialogue menu selection system 4 and causes the dialogue menu selection system 4 to select a menu based on the operator's dialogue intention and dialogue history from the dialogue panel 2. , this menu is displayed on the interactive CRT 6.

In this way, the operator not only operates the plant 14 based on the guide displayed on the CRT group 10 via the information display system 12 using the plant diagnosis guide system 13 of the plant operation support system 9, but also operates the plant 14 based on the guide displayed on the CRT group 10 via the information display system 12. Since the outputted preconditions and the like can be understood using the man-machine dialogue device, the state of the plant 14 can be widely and quickly understood, and the plant 14 can be operated suitably.

In addition, since the CRT selection panel 3 is partitioned almost in the same way as the physical layout of the actual CRT group 10 (FIG. 4(A)), it is possible to select the CRT to be used and maintain the screen related to the judgment result. This is easy to do and reduces the burden on the operator's memory.

As described above, the man-machine dialogue device for a process plant according to the present invention includes a screen selection device in which the purpose and means of the plant and a two-dimensional hierarchical structure of the whole and parts are set, and a plant to be displayed as a screen. A menu determining device that determines a menu such as the type of system, a dialogue end interface device that integrates signals from these screen selection devices and the menu determining device and determines a screen to be displayed, and a signal from this dialogue end interface device. and a dialogue control system that determines the suitability of the plant operation support system and displays the screen on the display device of the plant operation support system.This man-machine dialogue device inputs the thinking process of the operator into the operation support system. As a result, through interaction between the operator and the plant operation support system, the operator can broadly and quickly understand the plant status and perform appropriate plant operation.
