Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention uses a display device to monitor abnormal conditions of a device to be monitored for abnormal conditions such as a plant and a processing device itself, and generates an alarm signal indicating the occurrence of an abnormal condition. The present invention relates to an alarm information processing method in a display device that provides visual displays in different ways that can clearly distinguish the importance or urgency level of the event.

[Conventional technology]

Recently, display devices have been used to monitor the operation and operating status of devices to be monitored for abnormal conditions, such as plants in all fields, and can be said to have the most important position as one of the man-machine interface functions.

The conventional alarm information processing method is 1. Alarms that occur due to changes in the state of equipment to be monitored for abnormal conditions such as plants, and alarms that indicate abnormal conditions of the processing equipment, are displayed as, for example, ``tracking error'' or ``keisanki error''. Generally, an alarm information processing method is adopted in which an alarm message or a guide message of several characters to several dozen characters is displayed on the display screen of the device.

[Problem that the invention seeks to solve]

However, in the conventional alarm information processing method described above, only a short message of the alarm is displayed on the display screen, so even if the alarm is of high importance or urgency, the display B There is almost no difference between the warning signals and the operators may overlook them, and even if they are monitored, it is difficult to determine the importance of the alarm signal, resulting in delays in taking appropriate countermeasures, or in some cases, no countermeasures being taken at all. There was a problem in that a situation could occur where the system could not be used, which could have a serious impact on the safe operation of the plant.

Furthermore, in general, when a serious failure such as a failure occurs in a processing device such as a computer, a situation occurs in which the data that has been displayed on the display device is lost. In such a case, after the processing equipment is restored, the operator must operate the input key on the display unit to follow the plant operating status, which requires a lot of time to input the data, and also There was also the problem that when you wanted to know what kind of data was displayed on the display device, you could not display it.

Therefore, the present invention has been made by focusing on the problems of the conventional method described above, and provides an alarm in a display device that allows an operator to easily judge the situation and take countermeasures and corresponding operations when an alarm occurs due to the occurrence of an abnormal situation. The purpose is to provide an information processing method. .

[Means for solving problems]

In order to achieve the above object, the present invention supplies an external alarm signal indicating the occurrence of an abnormal state of the abnormal state monitored device and an internal alarm signal indicating the occurrence of the abnormal state of the processing device itself to a level determining means, determining the level of importance or urgency of each alarm signal according to the type of each alarm signal by means;
Based on the determination result, the display control means forms alarm level information in different forms depending on the degree of importance or urgency, and displays this on the display device in place of the screen display information immediately before receiving the alarm signal. The present invention is characterized in that screen display information immediately before receiving an alarm signal is saved in a storage device.

[Effect]

In this invention, when an alarm signal from a device to be monitored for an abnormal state such as a plant and an alarm signal from the processing device itself are supplied, the level judgment means, for example, compares a preset alarm signal with its importance or urgency. The level of importance or urgency for the type of alarm signal is determined with reference to the memory table that stores the relationships, and if the determination result is that the level of importance or urgency is high, the display control means, for example, displays the Alarm information consisting of message information indicating the occurrence of the alarm, alarm level information consisting of a red background color and a pattern diagram indicating the alarm occurrence location is output to the display device and displayed, and at the same time, the display device displays the alarm information that is displayed on the display device at that time Save screen display information to a predetermined storage device. Further, when the level of importance or urgency of the alarm signal is low, the display control means outputs and displays alarm level information with only the background color being magenta, for example, on the display device together with the message information, and The screen display information displayed on the display device at that time is saved to a predetermined storage device. In this way, by displaying alarm display information that can be clearly distinguished according to the importance or urgency of the abnormal alarm signal, appropriate measures can be taken.

Then, in order to complete the action for the alarm signal and return to the normal monitoring state, read out the screen display information saved in the storage device before the alarm occurred, output it to the display device, and display the information before the alarm occurred. It is possible to easily return to the normal monitoring state by adjusting the display data that has undergone an event change to the current data.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a flowchart showing its processing procedure.

First, to explain the configuration, in FIG. 1, 1 is a monitoring processing device such as a computer that monitors the operating state of an abnormal state monitored device such as an external plant, and 2 is a CRT display to which the display information output is supplied. Display devices such as 3
4 is a keyboard, and 4 is a display state storage device.

The monitoring processing device 1 includes an alarm signal receiving section 5 that receives various alarm signals representing an abnormal state from an abnormal state monitored device and an alarm signal representing an abnormal state of the processing device itself. The alarm signal receiving unit 5 determines whether the received alarm signal is an alarm signal from an abnormal state monitored device or an alarm signal from within the processing device, and, for example, recognizes the former alarm signal as an “external signal”. The latter alarm signal is processed as an "internal signal."

Here, the alarm signals from the abnormal state monitored device and the processing device itself include detailed information indicating the location where the abnormal state has occurred as additional information.

The external signal and internal □ signal processed by the alarm signal receiving section 5 are supplied to the level determining section 6. This level judgment section 6
determines the level of importance or urgency by referring to the alarm level management table 7 that stores in advance the correspondence between the types of external signals and internal signals and their additional information, and the level of importance or urgency. The level of the signal is determined, and the corresponding level signal is added to the external signal or internal signal and additional information and output. Here, alarm level management table 7
is configured so that tables can be easily added and changed from the outside so that it can respond flexibly to changes in the system environment, and the judgment levels stored in it can be set steplessly. However, because the processing is complicated, it is actually set in three levels: severe, moderate, and mild.

The external signal or internal signal outputted from the level determination section 6, the additional information, and the level signal added thereto are supplied to the display control section 8. The display control unit 8 refers to the management table in the alarm information storage unit 9 based on internal or external signals, detailed information as additional information, and severe, medium, or light level signals indicating importance or urgency. Determine message information and message detailed information, and extract alarm level information consisting of a color code corresponding to the background on the display screen that indicates the importance or urgency of the alarm, and pattern information that clearly indicates the location where the alarm occurred due to the alarm signal. and currently display device 2
After saving the screen display information displayed in the display state storage device 4, each message information, message detailed information, and alarm level information consisting of background color code, pattern information, etc. are saved on the display device 2 as alarm information. Output.

Here, the management table of the alarm information storage unit 9 includes the type of external or internal signal, detailed signal information, and severity.

Medium or light level signals and corresponding message information indicating a rough message of the alarm occurrence location;
Detailed message information indicating the detailed occurrence location, background color code as alarm level information according to the level signal (for example, red for severe severity, yellow for moderate severity, magenta for light severity), and graphics indicating the location of the alarm occurrence. The relationship with the pattern information specified by is stored in advance. Here, the pattern information includes an external view of the processing device 1 or abnormal state monitored device indicating whether the alarm signal is an internal signal or an external signal, and a detailed view showing the location where the abnormality actually occurs inside the processing device 1. It consists of

Note that the screen display information saved in the display state storage device 4 is, for example, when the system of the processing device 1 is down, the screen display information immediately before the processing is stopped is saved in the display state storage device 4, so that the processing When the operator uses the keyboard 3 of the display device 2 to input data to follow the plant status after the equipment 1 has been stopped for a while,
After restoring the saved display information on the display screen of the display device 2, it is only necessary to input only the data that has changed.
The burden of data entry can be reduced.

Next, the operation of this embodiment will be explained according to the processing procedure shown in FIG.

Now, explanation will be given assuming that, for example, a memory abnormality has occurred in the processing device 1. When an alarm signal containing detailed signal information indicating a memory abnormality is supplied from the processing device 1 to the signal receiving section 5, it is processed as an internal signal by the receiving section 5, and this internal signal information and detailed signal information are sent to the level determining section. 6 (step ■).

In this way, when the internal signal information and signal detailed information are supplied to the level determination section 6, the priority level of the importance or urgency of the signal is determined by referring to the alarm level management table 7 based on these ( Step ■). In this case, since the memory abnormality is an important abnormality in performing monitoring processing, the "severe" level with the highest degree of importance is selected, and this is displayed in the display control unit 8 along with the internal signal information and detailed signal information. Supplied.

The display control section 8 first refers to the management table of the alarm information storage section 9 based on the internal signal information,
The message information for displaying "Error related to PU processing device" is read out, and then, based on the signal detailed information, the management table of the alarm information storage section 9 is similarly referred to to display, for example, "Error related to PU processing device".
Step (2) in which detailed message information for displaying "memory error" is displayed one after another (step (2)), and it is further determined whether the level signal is severe, moderate, or light (step (2)).

At this time, level 18 is severe, so the pattern information consists of a red background color code, a pattern diagram showing the processing device 1 based on internal signal information and signal detail information, and a pattern diagram of "memory" as its detailed diagram. is read out as alarm level information (step ①H).

Next, the screen display information displayed on the display screen of the display device 2 is saved to the display state storage device 4 (step ■), and then the message information, message detailed information, background color code, and pattern information are saved. The alarm level information is output to the display device 2 as alarm information (step 2).

Therefore, on the display screen of the display device 2, for example, message information such as "Error related to rCPU processing device" and detailed message information such as "Memory error" are displayed in the upper part of the display screen, and a pattern diagram of the processing device is displayed in the center. and a memory pattern diagram are displayed, and a display indicating a severe alarm level with a red background color is displayed as visual information.

Further, when the level determination section 60 determines that the level of the alarm signal is moderate, the process moves from step (2) to step (2)M, and the display control section 8 refers to the alarm information management table in the alarm information storage section 9. Then, the background color code with the background color as "yellow", the pattern diagram showing the general abnormality location, and the pattern information representing the detailed pattern diagram are read out as alarm level information, and then the process moves to step (2) above. After saving the screen display information displayed on the display screen of the display device 2 to the display state storage device, the process moves to step ■, and the alarm level information consisting of the background color code and pattern information representing medium level is stored in step ■. Together with the message information and message detailed information that have been sent successively, this information is visually displayed on the display screen of the display device 2 as alarm information in place of the conventional display information.

Similarly, when the judgment result of the level judgment unit 6 is that the level of the alarm signal is light, steps ① to ②L
, the display control section 8 refers to the alarm information management table in the alarm information storage section 9 and sets the background color to "magenta".
The alarm level information consisting only of the background color code is read out, and then the process proceeds to step (3), where the screen display information displayed on the display screen of the display device 2 is stored in the display state storage device 4.
Then, in step (2), the alarm level information is visually displayed on the display screen of the display device 2 together with the successive message information and message detailed information in step (2).

In this way, when an alarm occurs, alarm level information corresponding to the level of importance or urgency of the alarm signal is visually displayed on the display device 2 in place of the previously displayed information, so that the operator can There is no risk of missing alarm information, and the occurrence of an abnormal situation can be reliably recognized. Moreover, the background color and
Since the visual display includes different pattern diagrams, etc., there is no misjudgment of the importance or urgency of the warning, and prompt countermeasures can be taken against the warning. Moreover, the display device 3
When displaying alarm information, the display information that was displayed immediately before is saved to the display state storage device 4, so when the alarm countermeasures are completed, the operator can operate the keyboard 3 of the display device 2. By reading the display information saved in the display state storage device 4 and restoring it to the display screen of the display device 2, there is no need to create new display information.
By simply inputting only the data necessary to track event changes, it is possible to return to the normal monitoring state.

In addition, in the above embodiment, a case has been described in which information is a combination of background color and pattern information as alarm level information representing importance or urgency, but it is also possible to use any one of each information, Alternatively, the display color of message information or message detailed information can be changed depending on the degree of importance or urgency.

Further, an alarm signal from an abnormal state monitored device such as an external plant may include additional information indicating the location where the alarm has occurred.If the alarm signal does not include additional information, the alarm signal may be sent to the alarm signal receiving unit 2. It is also possible to analyze which signal line the alarm signal was received from and add additional information indicating a predetermined alarm occurrence location accordingly.

〔Effect of the invention〕

As explained above, according to the present invention, an external alarm signal indicating the occurrence of an abnormal state in the abnormal state monitored device and an internal alarm signal indicating the occurrence of an abnormal state in the processing device itself are supplied to the level determining means, and the level determining means determining the level of importance or urgency of each alarm signal according to the type of each alarm signal by means;
Based on the determination result, the display control means forms alarm level information for RE and jM that differs depending on the degree of importance or urgency, and displays this on the display device in place of the screen display data immediately before receiving the alarm signal. Since the screen display data immediately before the alarm signal is received is saved in the storage device, when an abnormal state occurs in the monitored device or an abnormal state occurs in the processing device, the data displayed on the screen of the display device is saved. Alarm level information is visually displayed in place of the previously displayed information, which makes it possible to reliably recognize the occurrence of an abnormal condition, and to determine whether the alarm level information is important or urgent based on the type of alarm signal. The degree of importance or urgency can be reliably determined.
It becomes possible to quickly take measures against the warning,
Furthermore, when alarm information is displayed on the display screen of the display device, the screen display information that has been displayed on the display screen up to that point is saved in the display state storage device, so for example, if the processing device remains stopped for a while, When an operator restores a device to be monitored in an abnormal state to a normal monitoring state, he or she can resume normal monitoring by simply reading out the display information saved in the display state storage device and inputting only the data that caused the event change. This has the effect of reducing the burden of data input on the operator.
