Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring screen display device using a CRT used for monitoring the operation of a plant or the like.

[0002]

2. Description of the Related Art In recent years, with the development of computer-related technology, a display device using a CRT has been widely used for monitoring the operation of a plant or the like. This display device is capable of displaying monitoring data of a plant or the like on various monitoring screens, and stores tens or hundreds of monitoring screens suitable for the purpose of monitoring.

Among them, various screens for displaying the presence / absence of an abnormality, the state of the abnormality, the history of the abnormality, and the like are prepared as a screen for monitoring the abnormality of the plant or the like. As an example, there is an alarm list screen in which a list of abnormal items that are occurring is displayed on one screen (a plurality of sheets if there are many abnormalities) so that only the currently occurring abnormalities can be checked at a glance. In such a screen, as shown in FIG. 5, considerations are given such as displaying in order of occurrence time and in order of alarm grade, and prompting confirmation by displaying a blink of an alarm which has not been confirmed by the operator. FIG. 5 is a diagram showing an example of a conventional alarm list screen display in which consideration is given to emphasizing abnormalities that the operator should deal with with the highest priority.

[0004] Here, in general, the actions to be taken by an operator when an abnormality occurs are considered as follows. (1) Check for the occurrence of an error (item, time, importance (grade)) (2) Investigate the cause and check the effect of the error (3) Implement the corrective action (if automatic control is enabled, check that automatic processing has started) (4) Plant operation monitoring after the corresponding measures (5) Abnormality recovery confirmation On the conventional CRT screen, (1), (4), and (5) can be directly confirmed, and for (2), abnormality diagnosis And other support systems. Regarding (3), automatic control processing (manual for low urgency) is supported, and it is not followed until the processing is executed or effective, and it can only be confirmed that the alarm is not recovered. is there.

[0005] For example, on the alarm list screen described above, it is only possible to confirm the occurrence and recovery of an alarm, and the identification of whether or not the corresponding alarm has been processed has not been performed.

Therefore, in a case where a plurality of abnormalities occur at the same time, such as during a power failure, it is difficult to take an appropriate countermeasure, and it often depends on the skill of the operator.

On the other hand, development and commercialization of suppressing display of unnecessary alarms and displaying alarms in the order of factors have been performed. However, such a system requires an artificial brain element, and its algorithm is complicated. Furthermore, since a knowledge database is also required, it is difficult for a general operation computer and monitoring control device to realize the processing in terms of both capacity and performance.

Further, it is economically difficult to install a dedicated computer for constructing such a system. In addition, the effects are not yet at an expected level because they are based on technologies that have not yet been established, and it is difficult to analyze and collect detailed characteristics and behavior of monitored objects. .

Therefore, as long as the monitoring screen display device incorporated in the current monitoring and control device is used, the operator is conscious of the occurrence of the abnormality displayed on the screen based on the importance (alarm grade) of the abnormality. Based on the experience and intuition of the operator to some extent, the corresponding measures will be taken.

[0010] The monitoring screen display device for displaying the alarm list screen as shown in FIG. 5 is configured as shown in FIG. FIG. 6 is a block diagram showing a configuration of a conventional monitoring screen display device.

In the first place, in the event of an abnormality, it is sufficient to take appropriate measures in response to the alarm that is occurring and to reset the alarm. The problem here is how to take action when a plurality of alarms occur. However, the information that can be provided by the operator when making a determination is currently only about alarm grade.

[0013] Generally, the higher the grade, the more urgent action is required, so it is possible to make the minimum judgment. However, for example, the following cases are sufficiently considered.
The best decision depends on the skill of the operator.

Case 1) When a plurality of same alarm grades occur Case 2) In many cases, high grade alarms are automatically controlled, while low grade alarms are often handled manually. If a low alarm is left untreated for a long time, the abnormality will be expanded.When recognizing the occurrence of an abnormality, the operator should confirm the abnormality based on the current alarm grade, which indicates the importance and impact of the abnormality. Is good. However, in order to perform an appropriate abnormality response measure, some kind of identification indicating the priority of the response at that time (this changes depending on the situation and time) is required.

However, at present, only the alarm grade is identified and displayed, and there is a demand for a monitoring screen display device that can display an emergency priority in a proper priority order.

First, when an abnormality has occurred, the control processing unit 52 in the control device 50 causes the automatic sequence processing S1, S2,. . . Is performed, and the command is output from the signal input / output processing unit 53. Since there are many interlock conditions in the automatic sequence start, the sequence is not always started when an abnormality occurs. Preparation operations for startup may be required.

In FIG. 2, when the "abnormal" occurs, the "△"
An example of an abnormality handling sequence S1, S2 for opening the “Δ valve 61” and operating the “□□ pump 62” is shown. However, neither the “△△ valve 61” nor the “□□ pump 62” can be opened and operated without any condition, and the permission conditions (a ₁ , a ₂ ,..., A _m ), (b ₁ , b ₂ ,…, b _n )
There is. If any of the permission conditions is not satisfied at the time of occurrence of “XX abnormality”, it means that abnormality handling processing has not been performed.

The operator establishes the unsatisfied permission condition as necessary and sets the "△△ valve" open (sig1) and the "「 pump "operation (sig2). The following three operations are performed to determine whether or not the corresponding sequence has been started after the occurrence of the abnormality, including enabling the operator to accurately grasp whether the operation for satisfying the permission condition, the operation is necessary, and whether or not the operation has been performed. The determination is made based on the AND logic of the condition.

1) During the occurrence of an abnormality 2) The corresponding automatic response sequence command is established 3) The final answer of the operation of the device With the above logic established, the "error response processing" (ST

FIG. 3 is an explanatory diagram showing a state in which the priority of the abnormal time response is identified and displayed on the alarm list screen of the present embodiment and the unsupported and handled alarm list screens.

FIG. 4 is a flowchart of screen processing of each alarm screen and the like according to the present embodiment. The alarm list screen 71 shown in FIG. 3 displays a list of the minimum information such as the tag number, the name, and the content of the alarm item A71 that is occurring, as shown in FIG. Also displays unconfirmed alarms).

Of the alarm items A71 being displayed on the alarm list screen 71, the item "Abnormal response processing" in FIG. 2 is not satisfied but the automatic response is performed, but the automatic response is not activated, and the manual response item. Is also displayed as an alarm item A72 on the unsupported alarm list screen 72.

Of the alarm items corresponding to the automatic operation, those for which the “in the process of handling abnormalities” shown in FIG. 2 has been established and the automatic operation has been activated are also displayed as an alarm item A 73 on the alarm list screen 73 corresponding to the alarm.

Also, of the alarm items A72 in the unsupported alarm list screen 72, the touch panel 30
The item that has been manually dealt with by the touch operation on the displayed symbol is switched to the display on the handled alarm list screen 73 and the alarm item A73.

In the alarm item A73 displayed on the corresponding alarm list screen 73, if the alarm continues even after the lapse of the predetermined time, it is determined that the corresponding action is invalid, and the display on the unsupported alarm list display 72 side is performed. Alarm item A72
Switch to

The above-described display processing between the three screens will be described with reference to the flowchart of FIG. First, when an alarm occurs (ST11), the alarm is displayed on the alarm list screen 71 (ST12).

If the processing content corresponding to the alarm is manually handled (ST13), an alarm item A72 is displayed on the unsupported alarm list screen 72 (ST1).
4), proceed to step ST19.

On the other hand, if the processing content corresponding to the alarm corresponds to the automatic control (ST13), it is further determined whether or not the automatic processing operation has been performed.
4 (ST15), and if the automatic processing has not been performed, the corresponding alarm item A72 is blink-displayed on the non-compliant alarm screen 72 (ST16).

On the other hand, when the automatic processing is performed in step ST15, the display of the unsupported alarm list screen 72 is also displayed as the alarm item A73 on the corresponding alarm list screen 73, and the process proceeds to step ST17.

In step ST17, as shown in FIG. 2, it is determined whether or not the alarm is recovered within a predetermined time. If not recovered, the process proceeds to step ST16, and if recovered, a recovery display is displayed on the alarm list screen 71. (ST1

In step ST 16, the automatic processing is not performed as described above, or the automatic processing is started but the alarm is not recovered, the corresponding alarm item A 72 on the unsupported alarm list screen 72 is displayed as a blink. Have been.

Next, if the corresponding process is not performed within a predetermined time (ST19), the process returns to step ST16. If the corresponding process is performed (ST19), the corresponding symbol in the unsupported alarm list screen 72 is displayed by the operator. When touched (ST20), the display of the unsupported alarm list screen 72 is also displayed as the alarm item A73 on the handled alarm list screen 73, and the process proceeds to step ST17.

When the predetermined condition is satisfied as described above (ST17 and the like), the process ends. The above is the flow of display on each alarm list screen. In the present embodiment, for example, the following processing is also possible.

First, when there are a plurality of alarm items on the unsupported alarm list screen 72, the alarm items can be displayed, for example, in order of occurrence time and in order of alarm grade. Furthermore,
These are displayed as the priority of the corresponding process by displaying the presence or absence of operator confirmation, those that have been left for a predetermined time with no response, those redisplayed due to invalidation of the response, and the like by color display, blink display, etc. You. Here, for example, items that have been left unsupported for a predetermined period of time, items that have been redisplayed due to invalidation of the corresponding measures, and the like may be regarded as items with high priority.

Accordingly, by monitoring the three types of screens, it is possible to confirm the alarm items that are occurring, their contents, whether or not alarms have been processed, the list of items that need to be processed, and their priorities. It is possible. Such a priority determination means is constituted by, for example, the screen creation processing unit 14, the alarm data occurrence / recovery detection unit 12, and the abnormality handling treatment status monitoring unit 16 in FIG.

By such an operation, it is possible to assist the operator in handling the abnormality. The three types of screens can be configured to display each other in a window or to display three types of screens on one screen. Furthermore, it is also possible to automatically display an interrupt when an abnormality occurs, when a response operation is performed, when a response is invalidated, and the like. This facilitates a more appropriate abnormality handling operation.

As described above, the monitoring screen display device according to the embodiment of the present invention includes
An alarm data generation / recovery detection unit 12, a screen input processing unit 13, a screen creation processing unit 14, and an abnormality handling procedure status monitoring unit 16 are provided to monitor the operation status of the automatic sequence and operator input, and to perform processing for the corresponding processing when an abnormality occurs. Since the status is displayed using the alarm list screen 71, the unsupported alarm list screen 72, and the handled alarm list screen 73, the state is less affected by the skill of the operator, and when a plurality of abnormalities occur, The priority of the response measures is identified and displayed, and the abnormal response measures can be performed in the proper priority order.

The above operation and effect are further summarized, and the present invention has the following effects. 1) When a large number of alarms are generated at the same time, for example, when a power failure occurs, it is possible to easily determine an item having a high priority of response.

2) Since the correspondence completed / unfinished is automatically determined, it is possible to prevent forgetting to respond due to a wrong memory or a careless mistake. 3) It is possible to prevent an alarm that does not require an emergency response from being left for a long time to expand the abnormality.

4) If the abnormality handling process is invalid, the next handling process can be executed early. The present invention is not limited to the above embodiment, and can be variously modified without departing from the gist of the invention.

The method described in the embodiment can be executed by a computer as a program that can be executed on a storage medium such as a magnetic disk (floppy disk, hard disk, or the like), an optical disk (CD-ROM, DVD, or the like), or a semiconductor memory. It can also be stored and distributed.
