Abstract

PURPOSE:To avoid waste dispatch of a clerk in charge in a supervising center by providing in a report processor a signal falldown processing part detecting a report command signal for its falldown reported to the supervising center. CONSTITUTION:When a sensor 1 detects an elevator for its trouble, a signal of abnormality of the sensor 1 is input to a trouble detector 3 and transmitted as a trouble signal 3a to a trouble collector 4 here collected by each kind of the trouble generating a report command signal 4a stored. A waveform of the signal 4a, as shown in a dotted line, is turned off when the trouble is none, rising up on when the trouble is generated and falling down off when the trouble is recovered. This signal 4a is input to a report processor 5 detecting in a signal riseup processing part 6 a riseup of the signal 4a reported to a supervising center 9 through a telephone line 8. When the elevator is restored from its trouble to a normal condition, a signal falldown processing part 7 detects a falldown of the signal 4a to be reported to the supervising center 9 through the line 8.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an elevator failure monitoring device.

[Prior art] A conventional elevator failure monitoring device is disclosed in Japanese Patent Application Laid-Open No. 63-20
It is described in Publication No. 749, etc., and its gist will be explained with reference to FIG.

An abnormality signal from a sensor 1 connected to an elevator control panel (not shown) is input to a failure detection device 3 via an elevator transmission line 2. Here, the abnormality signal is transmitted as a failure signal 3a to the failure aggregation device 4, where it is aggregated for each type of failure and stored as a notification command signal 4a. As shown in the dotted line, the waveform of the notification command signal 4a is such that it remains OFF unless there is a failure, rises when a failure occurs, and remains ON until recovery. This notification command signal 4a is sent to the notification processing device 5.
As shown in the dotted line in the figure, the rise of the ON state indicating a failure is detected, and the monitoring center 9 is notified via the telephone port uA8. This eliminates the need to increase communication line capacity and makes it easier to discover the cause of failures.

[Problems to be Solved by the Invention] Since conventional elevator failure monitoring devices are configured as described above, even if the abnormality is recovered immediately after an abnormality in the elevator is detected and an alarm is issued, the failure monitoring device for the elevator is configured as described above. is not reported to the monitoring center, and among the many types of failures that occur in elevators, such as alarms due to the operation of door overload devices, if the original state is restored, the staff at the monitoring center will not have to go to the failure site. It is conceivable that when a supervisor at the monitoring center rushes to the failure site due to a low-importance alarm, the failure condition may have already been recovered.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator failure monitoring device that can avoid wasteful dispatch of staff at a monitoring center.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a notification system having a signal rise processing unit that collects fault signals, detects the rise of a converted notification command signal, and reports the signal to a monitoring center. The present invention is characterized in that the processing device is provided with a signal fall processing unit that detects the fall of the notification command signal and notifies the monitoring center.

[Function] Since the elevator failure monitoring device according to the present invention is configured as described above, the notification command signal transmitted to the first notification processing device is detected by the signal rising processing section, and also by detecting the rising edge of the signal. The fall processing unit also detects the fall of the signal, and this is reported to the monitoring center, so the staff will be informed that the report command signal is a low-importance alarm and has already recovered. will be informed. As a result, when an employee of the monitoring center is dispatched to the scene after receiving notification of an elevator malfunction, there is no possibility that the elevator malfunction has already been resolved.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an elevator failure monitoring device showing one embodiment of the present invention, and will be explained together with the operation flowchart of FIG. 2.

In step S1, when the sensor 1 connected to the control panel of the elevator (not shown) detects a failure of the elevator, the abnormality signal is input to the failure detection device 3 via the elevator transmission line 2. Here, as in step S2, the input abnormal signal is transmitted as a failure signal 3Ω to the failure aggregation device 4, and as shown in step S3, it is aggregated for each type of failure and made into a notification command signal 4a, be remembered. Here, as shown in the dotted line, the waveform of the notification command signal 4a is such that it remains OFF if there is no failure, rises and continues to be ON when a failure occurs, and falls and returns to the OFF state when recovery occurs. It is something.

Such a notification command signal 4a is input to the notification processing device 5 in the next step S4. Inside, step S5. As shown in S6, the signal rise processing unit 6
The rising edge of the notification command signal 4a is detected, and a notification is sent to the monitoring center 9 via the telephone line 8.

When the elevator failure returns to normal, the signal fall processing unit 7 detects that the 1 notification command signal 4a has fallen, that is, that the elevator failure has been restored. This will be reported to the monitoring center 9 via the telephone line 8, as shown in step S8.

In this way, along with the rising edge of the 1 report command signal 4a, a falling edge indicating failure recovery is also reported to the monitoring center 9, so that the staff in charge can confirm that the alert is of low importance and that the recovery has been made quickly. will be informed. As a result, it is possible to avoid unnecessary dispatch of staff, and it is also possible to respond only to alarms of higher importance.

[Effects of the Invention] As explained above, the present invention detects and reports not only the rising edge of the notification command signal due to an abnormality in the elevator, but also the falling edge of the notification command signal. In the case of a low-level alarm and a quick recovery, it is possible to avoid wasteful dispatch of staff at the monitoring center, such as rushing to the site where a failure has occurred each time an alarm is issued.
