Description

  The present invention relates to an alarm information display device and an alarm information display method for displaying alarm information generated in a plant, and an alarm information display device and alarm information in which important alarm information can be reliably recognized and alarm information that can be displayed is not limited. It relates to the display method.

  As a system for displaying alarm information transmitted from a plant, a system for displaying a message indicating alarm information on a screen in real time is known. In such a system, for example, when an alarm is notified with two levels of importance, if a certain process value rises and exceeds a low level threshold, a low level (medium alarm) alarm is issued and this alarm is dealt with. Alarm information to be displayed is displayed. Further, when the process value continues to rise and exceeds a high level threshold, a severe (severe alarm) alarm is issued and alarm information corresponding to the severe alarm is newly displayed. For this reason, two alarm information having different importance levels are displayed side by side.

  Patent Document 1 describes an alarm display device that displays an alarm generated in a plant in accordance with an alarm importance level.

And a function for displaying other alarm information.

  Hereinafter, an embodiment of an alarm information display device according to the present invention will be described with reference to FIGS.

  FIG. 1 is a block diagram illustrating a configuration example of a plant control system in which the alarm information display device of the present embodiment is used.

  As shown in FIG. 1, the plant control system is distributed in each part of the plant, field controllers 2, 2,... Controlling field devices 1, 1,..., And alarm information from each part of the plant control system. And a terminal device 3 for displaying the same. The field controllers 2, 2,... And the terminal device 3 are connected to each other via a communication line 4.

  As shown in FIG. 1, the terminal device 3 is stored in the storage unit 31 and the storage unit 31 that sequentially stores the alarm information of the alarm generated in the plant in association with the importance of the alarm information and the generation time of the alarm. The first display means 32 that displays only the alarm information defined as having the highest importance among the alarm information and the alarm information stored in the storage means 31 are limited to the alarm information having the highest importance. The second display means 33 for displaying without being performed, and the accepting means 34 for accepting selection of the display by the first display means 32 or the display by the second display means 33 are configured.

  FIG. 2 is a flowchart showing an operation procedure of the storage unit 31 of the terminal device 3.

  The storage unit 31 receives alarm information transmitted from each part of the plant and stores it.

  In step S1 of FIG. 2, the storage means 31 waits for the alarm information to be received and proceeds to step S2. The alarm information includes a message indicating the content of the alarm and the alarm information source (alarm source) and the importance of the alarm. The alarm information includes the date and time of transmission. The source of the alarm information is recognized as a tag name or slot number associated with the field device 1 or a parameter held by the field device 1.

  In step S2, old alarm information is deleted according to a predetermined condition. Thereby, the number of alarm information stored in the storage means 31 can be limited to a certain level. For example, the number of alarm information to be stored for each alarm source can be determined. Further, the number of alarm information having the same importance for the same alarm source may be limited to a certain value.

  Next, in step S3, the alarm information received in step S1 is stored, and the process returns to step S1. Each alarm information is stored as a record in which the above-mentioned message, alarm information transmission source, alarm importance, and transmission date / time are associated with each other.

  Next, the display operation in the terminal device 3 will be described.

  FIG. 3 is a diagram illustrating how an alarm is generated in accordance with a change in process value. FIG. 3A shows a case where an alarm is generated when the process value rises beyond a predetermined threshold. Such alarms include HI alarms (medium alarms) and HH alarms (heavy alarms) having different levels of importance.

  When the process value rises and exceeds the HI alarm threshold at time t1, a HI alarm is generated. The terminal device 3 receives the alarm information of the alarm, and the alarm information is stored in the storage unit 31.

  FIG. 4A shows a display screen by the first display means 32 when the HI alarm is generated. Usually, the display by the first display means 32 is selected as a default.

  When the alarm information of the HI alarm is stored in the storage means 31, the first display means 32 acquires the alarm information from the storage means 31 and displays it. As shown in FIG. 4A, the alarm information 51 of the HI alarm displayed on the screen includes an alarm occurrence date / time 51A, an alarm source 51B, and an alarm importance 51C.

  As shown in FIG. 3A, when the process value further increases and exceeds the HH alarm threshold at time t2, an HH alarm is generated. The terminal device 3 receives the alarm information of the alarm, and the alarm information is stored in the storage unit 31. FIG. 4B shows a display screen by the first display means 32 when the HH alarm is generated.

  Since the alarm information of the HH alarm is defined as more important than the alarm information of the HI alarm, the first display unit 32 acquires the alarm information from the storage unit 31 and displays it. As shown in FIG. 4B, the alarm display 51 on the screen is deleted and only the alarm information 52 of the HH alarm is displayed. The alarm information 52 of the HH alarm displayed on the screen includes an alarm occurrence date 52A, an alarm source 52B, and an alarm importance 52C.

  FIG. 4C shows a display screen when the display by the second display means 33 is selected via the receiving means 34 from the display state of FIG. When the “+” icon 61 shown in FIG. 4B is clicked, the display is switched to the “−” icon 62 as shown in FIG. The second display means 33 acquires the alarm information 52 from the storage means 31, and displays the alarm information 51 in a tree shape below the alarm information 52.

  When the “-” icon 62 shown in FIG. 4C is clicked, the tree display is folded, and the display screen is returned to the display screen by the first display unit 32 shown in FIG. Thus, the display by the first display means 32 and the display by the second display means 33 can be freely switched by the user's operation.

  Note that the importance of the alarm information may be defined in three or more stages. In this case, only the most important alarm information is displayed in the display by the first display means 32. As will be described later, in the display by the second display means 33, all alarm information is displayed regardless of the importance. The alarm information displayed by the first display means 32 is alarm information that satisfies a predetermined criterion.

  FIG. 5 is a diagram illustrating a case where alarm information from a plurality of alarm sources is displayed in a mixed manner. FIG. 5A shows a display by the first display means 32, and only alarm information having the highest importance is displayed among alarm information from the same source. In addition, as shown in FIG. 5A, the alarm information is displayed in chronological order according to the occurrence date and time. In FIG. 5A, newer alarm information is displayed in the lower part.

  When the “+” icon 61 shown in FIG. 5A is clicked, as shown in FIG. 5B, the second display means 33 acquires all alarm information about the alarm source from the storage means 31, and Is displayed. As a result, the alarm information 54 of the alarm source is expanded and displayed in a tree shape. When the “-” icon 62 is clicked, the tree display is folded, and the screen is returned to the display screen by the first display means 32 shown in FIG.

  Further, as shown in FIG. 6, all alarm information stored in the storage means 31 can be displayed in chronological order by a predetermined operation. In this example, the latest alarm information is displayed at the top and older alarm information is displayed at the bottom.

  FIG. 7 shows a display example by the second display means 33 when alarms from the same source include those of a plurality of importance levels.

  In the example of FIG. 7, alarm information from the same source is grouped according to importance, and each group is displayed as a group. Further, a group of alarm information with high importance is arranged at the upper level. For example, the alarm information 55 regarding the HH alarm (heavy alarm) is positioned at the uppermost position, and the alarm information 56 regarding the HI alarm (medium alarm) is disposed below the alarm information 55. Furthermore, alarm information with low importance is arranged below the alarm information.

  The number of alarm information stored in the storage unit 31 is defined for each group. In this example, ten pieces of alarm information are stored for each group, and all stored alarm information is displayed.

  Further, alarm information is arranged in time series in each group.

  When the “−” icon 62 is clicked from the display state shown in FIG. 7, the tree display is collapsed, and the display is switched to the display of only the alarm information 55 a by the first display means 32. Other alarm information is deleted.

  As described above, according to the alarm information display device of the present embodiment, a display state in which only the most important alarm information in the same source is displayed and all alarms are saved while storing necessary alarm information in the storage unit. An operator can arbitrarily select a display state for displaying information. Therefore, it is possible to display other alarm information according to the user's selection while realizing the “Eclipse” function that shows only the most important alarm information notified from the same alarm source. Therefore, necessary information can be given to the operator accurately, and the operator can perform operations such as selecting a display state with peace of mind.

  Further, if the user can set the importance of the alarm information, it is possible to obtain a flexible display form according to the plant status and the like. In this case, as shown in FIG. 1, an importance level table 35 for associating alarm information with its importance level may be provided, and the importance level table 35 may be configured to be created and modified by the user. Since the first display unit 32 and the second display unit 33 can acquire alarm information necessary for display by referring to the importance level table 35 when accessing the storage unit 31, the importance level set by the user is obtained. Alarm information can be displayed according to
