  The monitoring device 20 includes a notification unit 24, a timer unit 26, a timer changing unit 28, and a transmission / reception unit 30.

  The reporting unit 24 is connected to the monitoring unit 22, and when the abnormality signal of the facility 14 is input from the facility 14 to the monitoring unit 22, it reports the abnormality signal to the monitoring center 16 as abnormality information. Further, the reporting unit 24 has a function of reporting the same abnormality information to the monitoring center 16 again based on a predetermined time T1 elapsed signal from the timer unit 26 described later. That is, the reporting unit 24 repeats the reporting operation with respect to the monitoring center 16 with a predetermined time T1 while the abnormality signal of the facility 14 is continuously generated and continuously detected.

  The timer unit 26 is a device that measures time. The timer unit 26 starts measuring time based on the reporting operation of the reporting unit 24. When the measurement time reaches a predetermined time T1 set in advance, the timer unit 26 outputs a predetermined time T1 elapsed signal to the reporting unit 24. The predetermined time T elapsed signal includes abnormality information generated by the reporting unit 24 and information indicating that the predetermined time T1 has elapsed since the start of timing based on this information.

  The timer changing unit 28 is a device that changes a predetermined time T <b> 1 set in the timer unit 26. The predetermined time T1 is the time from the time when the abnormality of the facility 14 is reported as abnormality information, and the time is, for example, 5 minutes. The timer changing unit 28 can change the predetermined time T1 to a predetermined time T2 (for example, 30 minutes) longer than this.

  The transmission / reception unit 30 is connected to the reporting unit 24 and the timer changing unit 28 and the monitoring center 16 via the communication line 18, and transmits and receives information and signals between the monitoring device 20 and the monitoring center 16. The information and signals to be transmitted and received in the present embodiment include abnormality information, change command information that is information for operating the timer changing unit 28, and change completion information that is information indicating that the change has been completed.

  The monitoring center 16 includes a transmission / reception unit 32, a display unit 34, a work instruction unit 36, and a storage unit (not shown).

  The transmission / reception unit 32 is connected to the communication line 18 and transmits / receives information and signals to / from the transmission / reception unit 30 of the building 12.

  The display unit 34 is, for example, a display, and displays information from the monitoring device 20, specifically, abnormality information issued by the monitoring device 20 and worker information. Here, the information on the worker includes a field in which the worker is responsible, a work place of the worker, whether the worker is working, and the like. Further, the worker information also includes information indicating that the work instruction unit 36 has instructed.

  The work instruction unit 36 is an apparatus that instructs a worker to deal with an abnormality in the facility 14 based on the abnormality information. The work instruction unit 36 can automatically instruct the worker based on the abnormality information displayed on the display unit 34 and the worker information. Alternatively, the present invention is not limited to this configuration, and a supervisor stationed at the monitoring center 16 can select an appropriate worker, and the work instruction unit 36 can instruct the worker.

  The storage unit stores abnormality information, change command information, change completion information, and worker information.

  The monitoring center 16 includes an abnormal information frequent occurrence detection unit 38, a notification interval changing unit 40, and a notification unit 42.

  The abnormal information frequent occurrence detection unit 38 is a device that detects the frequent occurrence state of the same abnormal information from the monitoring device 20. The abnormal information frequent occurrence state is a situation in which the number n of notifications of the same abnormality information within the predetermined time Tx is equal to or greater than the predetermined number N1. Here, the predetermined time Tx is, for example, 1 hour, and the predetermined number of times N1 is, for example, 10 times.

  The abnormal information frequent occurrence detection unit 38 counts the time until the predetermined time Tx, and counts the number of times the abnormal information has been issued during that time, for example, when the reported abnormal information is the first one, not continuous on that day. To do. Then, the abnormal information frequent occurrence detection unit 38 detects that the abnormal information is in a frequent occurrence state when the number n of the same abnormal information in the predetermined time Tx is equal to or greater than the predetermined number N1.

  The reporting interval changing unit 40 causes the monitoring device 20 to change the reporting interval when the abnormal information frequent occurrence detecting unit 38 detects a frequent occurrence state of abnormal information. Specifically, the notification interval changing unit 40 outputs change command information to the timer changing unit 28. The timer changing unit 28 to which the change command information is input changes the predetermined time T1 set in the timer unit 26 to the predetermined time T2, and outputs the change completion information to the monitoring center 16.

  When the notification interval is changed by the notification interval changing unit 40, the notification unit 42 notifies the worker instructed by the work instruction unit 36 of the change content. This is to inform the worker that the reduction in the number of notifications is due to a change in the notification interval. The notification unit 42 can notify the worker based on the change command information from the notification interval changing unit 40 or the change completion information from the timer changing unit 28.

  Next, an example of the control operation of the system 10 will be described with reference to FIG. FIG. 2 is a flowchart showing the control operation of the system 10. The start of this control operation is the time when an abnormality occurs in the facility 14 and the monitoring unit 22 of the monitoring device 20 detects the abnormality signal.

  In step S101, the reporting unit 24 reports abnormality information to the monitoring center 16 based on the detected abnormality signal. At this time, the timer unit 26 starts measuring time.

  In step S102, the monitoring center 16 receives the abnormality information, and in step S103, the work instruction unit 36 instructs the worker to deal with the abnormality of the equipment 14 based on the abnormality information.

  In step S104, the abnormal information frequent occurrence detection unit 38 starts counting the timer and the number of times the abnormal information is issued the same as the abnormal information when the monitoring center 16 receives the abnormal information in step S102.

  In step S105, it is determined whether or not the number n of times of notification when the predetermined time Tx has elapsed is equal to or greater than the set number N1. When the number of times of reporting n when the predetermined time Tx has elapsed is equal to or greater than the set number of times N1, the abnormal information frequent occurrence detection unit 38 detects frequent occurrence of abnormal information and proceeds to step S106. On the other hand, when the number of times of reporting n when the predetermined time Tx has elapsed is less than the set number of times N1, the abnormal information frequent occurrence detection unit 38 determines that the abnormal information is not in the frequent occurrence state, and the control operation ends.

  In step S106, the notification interval changing unit 40 outputs change instruction information to the timer changing unit 28, and based on the information, the timer changing unit 28 starts from the notification interval, that is, from the predetermined time T1 set in the timer unit 26. Change to a large predetermined time T2. After the change, the timer changing unit 28 outputs the change completion information to the monitoring center 16.

  In step S107, the notification unit 42 notifies the worker instructed in step S103 of information that the notification interval has been changed, and the control operation ends.

  According to the system 10 of the present embodiment, when the number of times of reporting based on the same abnormality information occurs frequently, the reporting interval can be changed to be larger. By changing the notification interval in this manner, the number of notifications within a predetermined time is reduced compared to the number of notifications before the change, so that the communication cost associated with the notification can be reduced. Furthermore, since the number of times of reporting is reduced, the number of times abnormal information is processed in the monitoring center 16 is also reduced, so that the load on the monitoring center 16 can be reduced.

  In this embodiment, the case where the monitoring device 20 mainly manages the abnormality of the equipment 14 as the monitoring of the equipment 14 has been described, but not limited to this configuration, the management of the state of the equipment 14, the setting of the equipment 14, It is also possible to have a function of issuing an operation command for the facility 14.

  Moreover, although this embodiment demonstrated the case where the monitoring apparatus 20 had the alerting | reporting part 24, the timer part 26, the timer change part 28, and the transmission / reception part 30, this invention is not limited to this structure. These configurations 24, 26, 28, and 30 may be provided separately from the monitoring device 20 as a reporting device.
