Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator abnormal condition notification device, and more particularly to an elevator abnormal condition notification device that broadcasts the occurrence of an abnormal landing button to passengers.

[0002]

2. Description of the Related Art As disclosed in Japanese Examined Patent Publication No. 58-42110, a conventional device disables a hall button when a failure occurs in which the hall button continues to be pressed due to a smooth operation of the hall button mechanism. At the same time, there is a device for avoiding a failure in which the hall button is continuously pressed by generating a virtual call for another floor and moving the car up and down to the other floor.

Further, recently, a monitoring center for remotely monitoring an elevator via a communication line has been installed, detects a failure that the hall button is continuously pressed, and activates the communication line provided in the elevator with this detection signal. 2. Description of the Related Art There is provided a monitoring system that notifies a monitoring center of the occurrence of a failure, and a supervisor of the monitoring center dispatches a technician who repairs the elevator in which the failure has occurred.

[0004]

In the above-mentioned prior art, since the hall button continues to be pressed and does not respond to the faulty hall button, it is unreasonable not to call the hall even if the elevator is moving, or the elevator is not called. There was a problem that some floors could not be used.

Further, even if the failure is reported to the monitoring center, there is a problem that the elevator cannot be used on the relevant floor until the engineer repairs the malfunction of the mechanical part of the landing button. Further, the smooth movement of the mechanical portion of the landing button is often caused by the powder generated by the friction between the movable portion of the button and the button guide, and is easily restored by pressing the button again. Therefore, even if a technician receives a repair request from a monitoring staff for a failure due to a non-smooth operation of the mechanism of the landing button, the elevator is often operating normally.

An object of the present invention is to provide an elevator abnormal condition notification device capable of safely and quickly recovering from a failure in which a hall button is continuously pressed without dispatching a specialized engineer.

[0007]

To achieve the above object, the present invention provides a hall call registration detection circuit for registering a hall call for a floor by operating a hall button, and the hall button is continuously operated for a predetermined time. A timed circuit that detects the occurrence of a similar condition, a hall button abnormality detection circuit that detects an abnormality of the hall button when this time circuit operates, and a hall button abnormality detection circuit that detects an abnormality. In an elevator abnormal condition notification device for notifying an abnormal condition to a monitoring center that remotely monitors an elevator via a communication line, a voice synthesizing device that is activated in response to the operation of the hall button abnormality detection circuit, and the voice synthesizing device. And a speaker that broadcasts the method of recovering from the abnormality stored in FIG.

[0008]

Since the present invention is configured as described above, the present invention
When it detects that the hall button continues to operate due to the operation failure of the hall button mechanism, it broadcasts a method for recovering the failure of the hall button mechanism, which causes the hall button to continue being pressed. When an accident occurs, anyone can safely restore it, improving the efficiency of elevator use and eliminating unnecessary dispatch of technicians.
