Abstract

PURPOSE:To enable even such an operator whose has no sufficient knowledge nor experience to quickly call out the necessary screens in response to the areas of faults, by using a table which stores previously the information showing the relation among items. CONSTITUTION:A certain specific item requires attention for a menu screen displayed in a menu system owing to a fact that a fault occurs with a plant equipment related to each item. This information is displayed on the menu screen. Under such conditions, the corresponding item is selected and a detailed screen related to this item is displayed. Then the item to be selected next is retrieved out of a table in order to obtain a reply warning message and then the relative information. Thus the guidance is displayed on the menu screen in relation to the display of the item requiring attention. In such a way, an operator can know instantaneously the menu item to be called out for the detailed information on an emergency state like the occurrence of a fault, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a menu screen display method in an information processing device that monitors and controls the operating status of a plant or the like.

[Conventional technology]

FIG. 3 is an explanatory diagram showing an example of such a conventional menu screen. In the figure, 1 is a CRT screen, A is an item labeled "Overall process", and (A-1) is an item displayed as "Overall process", for example, "
(A-2) is the item labeled "Receiving raw materials", (A-2) is the item labeled "Crushing", (A-3) is the item labeled "Blending", and so on (A-4). ~(A-6) Continues.

Further, B shows an item labeled "Instrumentation Flow", C shows an item labeled "Control Flow", and similar items are displayed.

When the operator monitoring the screen instructs item A, ``Overall process'', using a mouse (not shown), this menu screen disappears and a detailed screen regarding ``Overall process'' is displayed. Next, after returning to the menu screen, if you specify another item, such as "receiving raw materials," a detailed screen related to it will be displayed. When a plurality of items are displayed on the details screen, by further selecting one of the items and specifying the item, a further details screen related to that item can be called up.

In this way, in an information processing device that monitors and controls the operating status of a plant or the like, a large amount of screen information is organized and stored by item.

[Problem that the invention seeks to solve]

By the way, in this menu screen display method, suppose that a failure occurs in, for example, plant equipment that belongs to the "grinding" process. The information processing device (not shown) naturally detects this and makes an announcement to that effect, for example, by voice, and also displays this on the menu screen by blinking the item "(A-2) r crush". do.

In this case, the operator must confirm the occurrence of the failure more specifically and then take appropriate measures in response to the occurrence of such a situation. Therefore, in order to specifically confirm the occurrence of the failure, it is necessary for the operator to call up screens containing related information one after another on the CRT screen.

In such cases, the conventional menu screen display method does not provide guidance on which screen to call up next depending on the location of the failure, so the operator must use all of his or her previous experience and knowledge. I had to judge and decide which screen to call next.

As a result, it may take time to make decisions, and the operator may lack the ability to quickly respond to emergency situations such as failures.
If the operator lacks sufficient experience, there may be omissions in the screens that should be called up, and the operator may not be able to obtain sufficient information to deal with the problem.

An object of the present invention is to solve the problems in the prior art, and to provide a menu screen that allows an operator to quickly call up a necessary screen depending on the location of a failure, even if the operator does not have sufficient knowledge or experience. The objective is to provide a display method.

[Means for solving problems]

In order to achieve the above object, the present invention imports various data related to the operating status of plants etc., organizes them by item and stores them in memory, displays only the items on the screen in a menu format, and selects a specific item. In the information processing apparatus, a detailed screen regarding the item is called up and displayed when the item is selected, and a table is provided in which information indicating the relationship between the items is stored in advance.

[Effect] When a specific item on the menu screen displayed in a menu format requires attention due to a failure in plant equipment related to the item,
When this is displayed on the menu screen, select that item to display the details screen for that item, and then
Furthermore, the item to be selected next in order to obtain related information is searched from the table, and guidance is displayed on the menu screen in association with the display of the item that requires attention.

〔Example〕

The present invention will now be described in detail with reference to the drawings.

FIG. 1 is an explanatory diagram showing a menu screen display in an embodiment of the present invention.

In the same figure, it can be seen that dashed arrows are displayed on the CRT display screen from item (A-1) of the ``raw material receiving'' process to item B of ``instrumentation flow'' and item C of ``control flow.'' Will.

This is because some kind of failure has occurred in the "raw material receiving" process, and there is a voice announcement indicating this, and even on the menu screen, the "raw material receiving" process item (A-
1) If there is a display indicating this (for example, a flashing or red display), the operator must determine that the next item to select is conventional in order to obtain further related information, as necessary. However, in the present invention, by searching a table prepared in advance in an information processing device (not shown), the operator automatically determines the item to be searched next, and in this case, Since these were item B of ``instrumentation flow'' and item C of ``control flow,'' item (A-1), B, and C were connected with arrows and displayed, and the operator was informed of this. That's why there is.

Therefore, the operator can clearly display the next item to be selected on the CRT screen as needed, without having to make a decision himself, so that he can quickly deal with the occurrence of a failure.

FIG. 1A shows the CP in the information processing device (not shown) when the menu of the next item to be selected is displayed on the CRT screen as just described.

It is a flowchart showing the flow of operations performed by U (central processing unit).

See Figure 1A. In step ■, the CPU:
Whether the state of each process in the plant changes or not (if the signal indicating the process state was previously 1, it changes from 1 to 0 or not, or whether the signal indicating the process state was previously 0) If so, we constantly monitor whether it has changed from 0 to 1. If a change is detected, the process proceeds to step (3).

In step ■, if the change is from 0 to 1, it is determined that an alarm has occurred (failure has occurred) and the process proceeds to step ■; if the change is from 1 to 0, the alarm recovery (
(Disaster recovery) and proceed to step ■.

In step (2), a new alarm generation bit in a memory (not shown) is turned ON and this fact is stored. Then, an alarm generation register (also not shown) is counted up by +1. Next, the process proceeds to step (2), where a table (not shown) is searched to find an item (alarm belonging screen) related to the item in which the alarm has occurred.

As a result, in step (2), an arrow pattern as shown in FIG. 1 can be determined. Next, proceed to step (2) to check whether or not the menu screen is being displayed. If it is being displayed, the arrow can be displayed in the next step (2).

In step ■, if the change is from 1 to 0 and the alarm is returned, proceed to step ■, count the alarm generation register (counter) by -1, and in step [phase] It is determined whether or not is zero, and if it is zero, the newly generated bit in the memory is returned to OFF in step 0.

FIG. 2 is an explanatory diagram showing a menu screen display in another embodiment of the present invention.

In the figure, double hatched items (in this example, (A-1) and C) indicate items displayed in red, and single hatched items (in this example, (A-6)) are displayed in magenta. Items without hatching indicate items displayed in blue.

That is, the item in which the alarm occurred and the related item that the operator needs to select next as necessary are displayed in red (more precisely, in a red frame). Also in this case,
Since the operator can immediately know which item he needs to select next, he can quickly deal with the occurrence of a failure.

If the operator points to an item displayed in red using a mouse, calls the screen to the CRT screen, and views the contents even once, then when the menu screen returns, the item will be displayed as the item where the alarm occurred. If the cause (failure) has not been removed, it will turn magenta. Only when the obstacle is removed will the item turn blue.

FIG. 2A is a flowchart showing the flow of operations performed by the CPU in the information processing device (not shown) when the above-described display is performed.

See Figure 2A. From step ■ to ■, step 1A
Same as in the figure. In step (2), items related to the failure occurrence item on the menu screen are displayed in red. Next, proceed to step ■, where it is determined whether the screen for the item displayed in red has been called up on the CRT screen at least once by the operator and its contents have been confirmed. If YES, step ■ The process proceeds to step (2) to turn off the newly generated bit, and the process proceeds to step (2)A to display the item in magenta.

Steps 1 to 0 are also the same as in FIG. 1A. In step 0, in the preceding step [phase], it is confirmed that the alarm generation counter is zero and the fault has been recovered, so the corresponding item is changed to blue to indicate that it is normal.

〔Effect of the invention〕

As explained above, according to the present invention, when an emergency situation such as a failure occurs, an operator who monitors and controls the operation of a plant or the like using a CRT display screen needs to call the operator to obtain detailed information. Since a certain menu item can be immediately known, even an inexperienced operator can quickly deal with the occurrence of a failure.
