Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator notification device for automatically making a notification to a monitoring center for remotely monitoring an elevator via a telephone line.

[0002]

2. Description of the Related Art Generally, in an elevator, when an earthquake exceeding a predetermined seismic intensity occurs during operation of a car, there is a concern that the car may cause an accident such as a collision with a counterweight. Therefore, an earthquake detector is installed in the building where the elevator is installed, and an emergency control device is installed in the elevator, and when the earthquake detector detects an earthquake that exceeds a predetermined seismic intensity, the emergency control device After the car is landed on the nearest floor based on the landing command output, the car is suspended on the nearest floor based on the operation suspension command. When the car is out of operation in this way, the building manager calls the maintenance company in charge of elevator maintenance by telephone, and based on this communication, the maintenance company dispatches a maintenance worker to the building, After checking the elevator and confirming that there is no abnormality, the car will be restarted.

However, since the influence of an earthquake is often over a relatively wide area, a large number of elevator cars are out of operation when an earthquake exceeding a predetermined seismic intensity occurs. For this reason, many building managers temporarily concentrate telephone calls to the elevator maintenance company, but due to the limited number of maintenance personnel, it is possible to perform restoration work on all elevators within a short time. No
Since this restoration work requires a long time, there is a problem that the elevator operation service deteriorates.

As one means for solving such a problem,
For example, as described in Japanese Patent Laid-Open No. 63-55698, when a car is put into a suspension of operation due to an earthquake, a first alarm is issued to a monitoring center to notify an abnormality via a telephone line. If the elevator is not restored due to the car being out of service even after the lapse of a predetermined time, then a second alarm indicating that the elevator is not restored is automatically issued via the telephone line. Elevator reporting devices have been proposed. In the monitoring center, the fact that the elevator has not been restored is displayed on the display device in response to the second notification. In such a conventional notification device, the operator of the monitoring center can surely grasp the unrestored elevator by the display of the display device, and in particular, it is selective for the unrestored elevator for a long time. It is possible to take measures such as dispatching maintenance personnel to.

[0005]

By the way, in the above-mentioned conventional elevator notification device, when a large earthquake occurs over a relatively large area, the first alarm for notifying the abnormality to the monitoring center is sent from a large number of buildings. There is a problem that the telephone line is considerably congested because it is transmitted via the line and the general call volume by the telephone is increased, and it takes a considerably long time to perform the above-mentioned first notification. ..

When the telephone line is extremely congested, the above-mentioned first alert may not be transmitted via the telephone line. When the first alarm cannot be automatically transmitted in this way, the building manager or the like needs to make a telephone contact to the monitoring center. For example, when the manager is absent at night, the above is required. There is a concern that the telephone contact of the company will be delayed until the next morning when the manager comes to work, and it will take a long time to restore the elevator.

The present invention has been made in view of the actual situation in the prior art as described above, and an object thereof is that the car is not in operation due to an earthquake even when a building manager or the like is absent. It is to provide an elevator notification device capable of notifying a monitoring center.

[0008]

In order to achieve this object, the present invention provides an operation stop output from an emergency control device when an earthquake detector installed in the same building detects an earthquake exceeding a predetermined seismic intensity. An elevator notification device provided in an elevator that suspends operation of a car based on a command, and which sends a notification to a monitoring center that remotely monitors this elevator via a telephone line, makes the building manager absent. An absent switch that is turned on when outputting an absence notification signal, a timer that starts in response to the output of both the absence notification signal and the operation stop command, and outputs a time completion signal after a predetermined time, and this time completion signal And a warning indicating that the car is in a suspension state according to the output of both the suspension instruction and the suspension instruction via the telephone line to the monitoring center. Are a configuration in which a road.

[0009]

Since the present invention is configured as described above, when an emergency stop command is output from the emergency control device due to the occurrence of an earthquake exceeding a predetermined seismic intensity after the building manager turns on the absent switch, The operation of the car is stopped by the output of the operation stop command, and the timer is activated to start the timekeeping operation in response to the output of both the operation stop command and the absence notification signal from the absence switch. After that, when the operation stop state of the car is not released within a predetermined time, the timer outputs a time measurement completion signal as the timekeeping operation is completed, and both the time measurement completion signal and the operation stop instruction described above are output. In response to the output of the above, the alarm circuit notifies the monitoring center via the telephone line that the car is not in operation. As a result, even when the building manager or the like is absent, it is possible to notify the monitoring center that the car is not in operation due to the occurrence of the earthquake.
