Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator calling device, and more particularly, to an elevator calling device that copes with a squeeze of a hall call button.

[0002]

2. Description of the Related Art Generally, when a passenger operates a hall call button in an elevator call system, a contact provided inside the hall call button is closed to register a hall call and a registration lamp is turned on. By the way, since the hall call button has a movable part, if it is used for a long time, the operation state may not be released and there may be a reluctance. The registration of the landing call is not canceled due to this obstinacy, and the car that arrives in response to the landing call does not close the door, so that the car cannot operate forever. When such a situation is detected, failure information "Do not close the door" is reported to the monitoring center, and the maintenance personnel rushes to restore the elevator.

However, in order to solve the problem that the elevator cannot operate until the maintenance staff arrives in the past, when the hall call is not canceled due to the obstruction of the hall call button, the hall call on the floor is disabled and the elevator Has been proposed, and an elevator call device that performs virtual hall call registration so that the elevator can be used on the floor has been proposed.

Incidentally, Japanese Patent Publication No. 58-4
The thing described in 2110 publication can be mentioned.

[0005]

By the way, in the above-mentioned conventional elevator calling device, since it is possible to use the elevator on the floor where the hall call button is uncomfortable.
The virtual hall call registration is performed to generate hall calls for the floor at regular intervals, but even when there are no passengers on the floor, the car is regularly on the floor for which the virtual hall call registration is performed. There is a problem in that the operation efficiency of the elevator is lowered because of landing on the floor, and the service to the passengers in the car and the passengers waiting on other floors is reduced.

The present invention has been made in view of the circumstances in the prior art as described above, and an object thereof is to reduce a decrease in driving efficiency due to the obstruction of the hall call button and to restore the obstructed hall call button. It is to provide an elevator calling device capable of urging an elevator.

[0007]

In order to achieve this object, the present invention provides a registration circuit for registering a hall call in response to an operation of a hall call button, and a car having a predetermined floor in response to the hall call. In an elevator calling device having a release circuit for releasing the hall call when the vehicle arrives at, a judging means for judging that the hall call button is in a tight state and outputting an output signal when the operation state continues for a certain period of time, and An extinguishing means for extinguishing the registration light of the hall call button according to an output signal, and a door closing means for forcibly closing the door according to each of the output of the output signal and the detection of the call to another floor. It is equipped with it.

According to the present invention configured as described above, when the operating state of the hall call button continues for a certain period of time, the judging means judges that the player is astringent and outputs an output signal. In response to this output signal, the extinguishing means extinguishes the registration light of the hall call button, and the door closing means calls the other floor when the output signal is being output, that is, the car stops. When a hall call or destination floor call on a floor other than the existing floor is detected, the door is forcibly closed so that the car can operate in response to the call to the other floor. As a result, the car operates in response to the call to the other floor, and then, in response to the landing call of the hall call button, which has been reluctant, drives to the floor and stops. It is possible to reduce a decrease in driving efficiency as compared with the case where the virtual hall call registration is generated at regular intervals. Further, since the registration light of the hall button with the astringency is turned off, another user can operate the hall button with the astringency to prompt the recovery of the hall call button with the astringency.
