Description

  The present invention relates to an elevator monitoring apparatus that remotely monitors equipment of an elevator.

  During the alarm test of the elevator monitoring device, a predetermined type of alarm was performed a specified number of times.

Conventionally, the work was performed only for the alarm test, but the work efficiency can be improved by performing the alarm test together with other tasks.

It has been proposed that a terminal device is provided with a function of detecting that an abnormal signal has occurred a predetermined number of times or more within a predetermined time during a notification test and restricting the transmission from being performed more than a predetermined number of times (see Patent Document 1). ).
JP-A-8-2559469

  According to the conventional technology, since the terminal has the number of times that can be issued and the effective time limit, if the work is delayed due to on-site conditions or the ability of the worker, the alarm test may not be completed even if the effective time limit is exceeded. There is.

  An object of the present invention is to provide an elevator monitoring device capable of setting the number of times that a notification can be issued and the effective time limit.

  In order to achieve the above-mentioned object, the present invention provides a plurality of types of detectors for detecting an abnormality in equipment of the elevator, a monitoring terminal for the elevator for monitoring the states of the plurality of types of detectors, a plurality of monitoring terminals and a communication line. A monitoring center connected to the monitoring center, detecting means for detecting that an abnormal signal from the plurality of types of detectors has been generated a predetermined number of times within a predetermined time, and transmitting the abnormal signal to the monitoring center. In the elevator monitoring apparatus having a transmission limiting means for limiting to a predetermined number of times, a setting means for setting the number of times of transmission of the abnormal signal and the effective time of the transmission control means by an operation terminal that can be detachably connected to the monitoring terminal It is equipped with.

  According to the present invention, since it is possible to set the number of times that an alert can be issued and the effective time limit, unnecessary alerts can be eliminated and the burden on the operator of the control center can be reduced. Can be done.

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

  FIG. 1 is a block diagram showing a configuration of a remote monitoring apparatus for an elevator according to an embodiment of the present invention, FIG. 2 is a flowchart showing a processing procedure for setting a notification restriction mode, and FIG. 3 is a notification restriction mode setting. FIG. 4 is a flowchart showing a processing procedure for checking the setting valid time limit in the alerting restriction mode.

  In FIG. 1, an elevator 1, an abnormality detector 2 for detecting an abnormality of the elevator, a control panel 3 for controlling the operation of the elevator, a monitoring terminal 4 connected to the control panel 3 and capable of monitoring and diagnosing an elevator state, and a telephone line 5 A monitoring center 6 connected to a plurality of monitoring terminals 4 via a telephone line 5 and an operation terminal 7 which is detachably connected to the monitoring terminal 4 and can individually set data.

  Next, the alerting restriction mode will be described with reference to the drawings.

  First, the processing procedure for setting the notification restriction mode in FIG. 2 will be described.

  In step 100, the operation terminal 7 is connected to the monitoring terminal 4.

  Next, in step 101, the type of notification to be restricted and the number of times that can be issued, which are specifications of the notification restriction mode, are input to the operation terminal 7.

  Next, in step 102, the effective time of the notification restriction mode is input to the operation terminal 7.

  Next, in step 103, a notification restriction mode is set from the operation terminal 7 to the monitoring terminal 4. The set data is stored in the RAM 43 of the control terminal. Here, the processing from step 101 to step 103 corresponds to the setting means.

  Next, in step 104, the connection between the monitoring terminal 4 and the production terminal 7 is removed.

  This completes the process of setting the notification restriction mode.

  Next, a processing procedure when an abnormality is detected during the setting of the alerting restriction mode in FIG.

  First, in step 200, an abnormality occurs in the elevator 1.

  Next, in step 201, the abnormality detection device 2 detects an abnormality of the elevator 1.

  Next, in step 202, the control panel 3 transmits an abnormality of the elevator 1 to the monitoring terminal 4.

  Next, in step 203, it is determined from the data stored in the RAM 43 of the monitoring terminal 4 whether the notification limiting mode is set. If set, the process proceeds to step 204. If not set, the process proceeds to step 205.

  Next, in step 204, it is determined whether or not the limited type of notification is generated from the data of the notification limitation mode stored in the RAM 43 of the monitoring terminal 4 and the notification has been detected more than the allowable number of times. Determine. If it has been detected, the process is terminated. If not detected, the process proceeds to step 205. Here, in the RAM 43 of the monitoring terminal 4, the type of notification that has been detected this time and the cumulative number of notifications are stored.

  Next, at step 205, the control terminal 4 issues an abnormal signal to the monitoring center 6 via the telephone line 5.

  This is the end of the process when an abnormality is detected during the notification restriction mode setting.

  Next, the processing for checking the valid setting time limit of the notification restriction mode will be described with reference to the processing procedure for checking the valid setting time limit of the reporting restriction mode shown in FIG.

  First, in step 300, it is determined from the data stored in the RAM 43 of the monitoring terminal 4 whether the notification limiting mode is set. If set, the process proceeds to step 301. If not set, the process ends.

  Next, in step 301, the set effective time is compared with the current time from the data in the notification limiting mode stored in the RAM 43 of the monitoring terminal 4. If the set valid time has passed from the current time, the process proceeds to step 302. If it has not elapsed, the process ends.

  Next, in step 302, the setting of the report restriction mode stored in the RAM 43 of the monitoring terminal 4 is canceled, and the kind of report and the total number of reports are cleared.

  This is the end of the processing for checking the effective time limit of the notification restriction mode. This process is automatically executed at a certain cycle.

It is a block diagram which shows the structure of the remote monitoring apparatus of the elevator of one Embodiment of this invention. It is a flowchart which shows the process sequence of the setting of alerting | reporting restriction | limiting mode in one Embodiment of this invention.
