[0001]

The present invention relates to a remote monitoring system for an elevator.

[0002]

2. Description of the Related Art Conventionally, a remote monitoring terminal for monitoring the operating status of each of elevators installed in buildings scattered in various places, and notifying a monitoring center serving an area where the elevator exists through a public communication line when an abnormality occurs. In the elevator remote monitoring system, which is installed in the monitoring center and receives the abnormality notification sent from the remote monitoring terminal, grasps what kind of abnormality has occurred in the elevator of which building, and informs the supervisor, Use a public telephone line for the communication line, register the telephone number of the monitoring center in the remote monitoring terminal, automatically call the telephone number when an abnormality occurs, and send the abnormality information to the own device when the line is closed. It is transmitted together with the ID code. On the other hand, on the remote monitoring device side, based on the received ID code, an error report is sent from the database registered in the device itself. Indexing the location of the remote monitoring terminal has to display the particular to display the location of the elevator with abnormality information, it is configured to notify the warden.

[0003]

However, in such a conventional elevator remote monitoring system, since the public telephone network is used for anomaly notification, if the public telephone network is cut off at the time of a disaster, it is difficult to use. However, communication between the remote monitoring terminal and the monitoring center cannot be performed, and the original purpose of the system cannot be fulfilled.

[0004] Further, when an abnormality occurs in an elevator of any building, it is necessary to accurately specify the location of the elevator and to instruct maintenance personnel, but especially when a wide area disaster occurs, the elevator was damaged by the disaster. Regional scope,
It is necessary to grasp the scale, etc., and to promptly support personnel who send in for recovery and take measures promptly.However, conventional elevator remote monitoring systems use the telephone number or maintenance number of each affected elevator to determine its location. The problem is that it is not possible to grasp how much damage has occurred geographically when a wide-area disaster has occurred because it only has the function of specifying, and it is not possible to take such measures promptly. There was also.

The present invention has been made in view of such conventional problems, and provides an elevator remote monitoring system capable of maintaining an elevator remote monitoring function even when a wired communication line is disconnected. With the goal.

Can be recognized, and a response for recovery can be promptly performed. If the map information displayed on the display device is printed out, the printout can be held by a maintenance person and sent to the site.

In the case where a large area disaster occurs and a large number of elevators are damaged, a display device on the remote monitoring device 2 side indicates how many elevators have been damaged and what area is affected. The operator can easily grasp the mark group of the location where the abnormality occurred on the map, and can quickly take recovery measures such as the number of engineers required for recovery work and the scale of support requests. become.

Further, when earthquake sensors of many elevators are activated due to the occurrence of an earthquake, conventionally, a large number of remote monitoring terminals 6 in various places send the same information to the monitoring center 1 via the communication line 4 at the same time. Although the communication line 4 is congested due to the notification of the volume, if only the position data is reported in the case of the earthquake sensing report as in this embodiment, the line occupation time can be shortened. However, it is possible to prevent the line from being punctured by simultaneous notification from a large number of remote monitoring terminals 6.

Next, a second embodiment of the present invention will be described with reference to FIG. The feature of the second embodiment resides in that the wireless communication line 10 is used for communication between the remote monitoring terminal 6 and the remote monitoring device 2 of the monitoring center 1.
