Japanese Unexamined Patent Publication No. 2016-141558

On the other hand, in an elevator system that manages multiple elevators as a group, calls are assigned to floors where demand for elevators is expected to increase, such as the reference floor (for example, the first floor) where the building entrance is located during work hours. In some cases, control is performed to automatically open the door by returning the car of an elevator that has not been used. By performing such control, it is possible to reduce the waiting time of the user in a crowded landing.

When this automatic door opening control is performed, both the car that has returned to the reference floor by the control and the car that has been assigned to the landing call and moved to the standard floor will open at the same time at the landing on the standard floor. Sometimes.

Therefore, in the elevator system that has been switched to the registration method by calling the destination floor, when the car that returned by the automatic door opening control and the car that was assigned to the landing call open at the same time, the user assigns it to the call. There is a possibility that the car will be in a different car. When such a situation occurs, the operating efficiency of the elevator system is lowered.

Therefore, in the elevator system configured to be able to switch the landing call registration method, the automatic door opening control is enabled only when the landing call registration method is switched to the registration method by up and down calling, and the elevator system is switched to the destination floor call registration method. When it is, the control is disabled.

However, when the automatic door open control is enabled / disabled in this way, immediately after the landing call registration method is switched from the destination floor call registration method to the vertical call registration method, the floor that is the target of the automatic door open control is used. Even if the registered unanswered destination floor call remains, the automatic door opening control may be executed. In this case, there is a problem that the user on the floor concerned may get in a different car from the car assigned to the call, and the operating efficiency of the elevator system may be lowered.

The present invention has been made in view of the above circumstances, and is an elevator system in which both a destination floor call registration device and a vertical call registration device are installed, and controls for automatically returning and opening a car to a predetermined floor. A group management control device for elevators to prevent users who have registered a landing call with the destination floor call registration device on the relevant floor from erroneously boarding a car other than the one assigned to the call. And the purpose is to provide a group management control method.

According to the embodiment for achieving the above object, the elevator group management control device manages a plurality of elevators in a group, is connected to the vertical call registration device and the destination floor call registration device, and switches to the registration method by vertical call. When it is called, the automatic door opening control is executed to return the car to which the call is not assigned to the specified floor and automatically open the door, and when the registration method is switched to the destination floor calling, the automatic door opening control is performed. It is provided with an automatic door opening control unit that does not execute automatic door opening control when there is an unanswered destination floor call registered on a predetermined floor after switching to the registration method by vertical call without executing.
