Description

  Embodiments described herein relate generally to a monitoring control system that notifies abnormality occurrence information.

In the monitoring and control system, various data are acquired from monitoring target devices installed in factories, plants, and the like, and when an abnormality or failure occurs, an alarm is given to the monitoring terminal in the monitoring room to display an abnormality.

In addition, in order to be able to notify the occurrence of abnormality even when the person in charge is absent in the monitoring room,
There is also a system for notifying occurrence of an abnormality by e-mail or the like.

JP 2002-149233 A

In the conventional monitoring control system, it is possible to notify the person in charge who is not in the monitoring room of the occurrence of an abnormality.

However, if there is a person in charge at the site where the target device in which an abnormality has occurred, it may not be necessary to go to the site, and unnecessary mail may be transmitted.

Accordingly, it is an object of the present invention to provide a monitoring control system that can efficiently monitor and recover from a failure by dividing the correspondence for each type of alarm.

The monitoring control system of the embodiment monitors abnormality information acquisition means for acquiring abnormality information of a monitoring target device, and abnormality information of a predetermined type of abnormality information to a terminal having a high priority after the first predetermined time has elapsed. A first abnormality information notifying unit for notifying an abnormality of the target device, and a failure recovery determination for determining whether or not the failure has been recovered after a second predetermined time has elapsed after being notified to the terminal by the first abnormality information notifying unit. And when the failure recovery determination means determines that the failure has not been recovered, a second notification is made to notify the abnormality of the monitored device to the terminal having the second highest priority after the previously notified terminal.
Anomaly information notification means.

The block diagram of the monitoring control system of embodiment. The flowchart which shows operation | movement of the monitoring control apparatus of embodiment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a configuration diagram of a monitoring control system according to a first embodiment of this invention.

The supervisory control system transmits / receives information between the supervisory control device 1 that acquires various data from field devices arranged in factories, plants, etc. and monitors abnormalities and failures of the field devices, and the supervisory control device 1. The terminal 2 which performs.

The supervisory control device 1 is an input / output means 1 for acquiring various data of the field device 3 via the field board 4.
1, an abnormality monitoring unit 12 that monitors an abnormality based on various data of the field device 3 from the input / output unit 11 and notifies the abnormality, and information that transmits information to the terminal 2 based on an instruction from the abnormality monitoring unit 12 It has the transmission / reception means 13 and the display means 14 which displays various data including abnormality.

Next, the operation of the monitoring control device 1 will be described using the abnormality monitoring flowchart of FIG.

When an abnormality occurs in the field device 3, the information is acquired via the input / output means 11. (Step 1)
Based on the abnormality information from the field device 3, the abnormality monitoring means 12 warns whether the abnormality needs to be dealt with within a certain period of time, whether it is an abnormality that requires immediate action, or an abnormality that does not require action. Sort by type. (Step 2) Here, an abnormality that needs to be dealt with within a certain period of time is an abnormality that needs to be dealt with. It can recover from a failure.

If it is an abnormality that needs to be dealt with within a certain period of time, it is counted up until a certain period of time has elapsed (step 3). If so, proceed to Step 5, and if the failure has been recovered, proceed to Step 9. (Step 4)
In step 5, information that an abnormality has occurred is notified to the person in charge to the terminal 2 via the information transmission / reception means 13. At this time, based on the database storing the person in charge who performs the notification, the terminal 2 of the person in charge with a high priority is notified.

After notifying the terminal 2, it counts up until a specified time elapses (step 6),
When the specified time elapses, it is determined whether or not the failure has been recovered. If the failure has not been recovered, the process returns to step 5 and the next highest priority person in charge is notified and the failure is recovered. If yes, go to Step 8. (Step 7)
When the failure has been recovered, the failure is notified to the terminal 2 of the person in charge who made the notification in step 5, and then the process is terminated. (Step 8, Step 9)
Further, when it is determined in step 2 that the abnormality requires immediate response, the process proceeds to step 5 to execute processing subsequent to the notification to the terminal 2 without waiting for a certain period of time.

If it is determined in step 2 that the abnormality is unnecessary, step 9
Proceed to ending the process. An abnormality that does not need to be dealt with is a minor abnormality that is highly likely to be a transient abnormality or that can be handled by a person in charge of monitoring the display means 14.

In this way, by performing a preset response for each type of alarm, it is possible to efficiently monitor and recover from a failure.

In particular, when there is a person on site and immediate response is possible, it is possible to prevent useless notification of abnormality. In addition, by notifying the terminal of the abnormality, it is possible to prevent oversight of the abnormality that needs to be dealt with even when the person in charge of the monitoring room is absent. Furthermore, when the failure is recovered, the failure recovery information can be shared by notifying the terminal that has been notified of the failure recovery information.

In the present embodiment, transmission / reception of information between the monitoring control device 1 and the terminal 2 may be email notification or voice telephone notification. The terminal 2 may be a mobile terminal such as a mobile phone or a fixed terminal such as a fixed phone. Since the person in charge carries the mobile device, the person in charge can be notified directly, but it may not be received outside the service area, so by registering a fixed terminal such as an office in addition to the mobile terminal, Anomalies can be dealt with more reliably.

The type of alarm may be subdivided according to the level of abnormality, and the notification method to the terminal may be changed accordingly. For example, notification is made to a plurality of terminals 2 for those having a high degree of abnormality, and notifications are given to terminals 2 having a lower degree of importance than those having a higher degree of importance. You may make it do. As a result, it is possible to more reliably deal with an abnormality with a high importance.

Further, it is possible to create a database by recording the contents of the actions taken at the time of failure recovery, and make it accessible from the terminal 2. Thus, it is possible to check the response history when an abnormality occurs, which can be used for countermeasures.
