Abstract

An elevator group control system, which can perform an appropriate operation so that a user can shorten the time spent until the user arrives at a destination floor in a double-deck elevator performing a double operation in at least one running direction, including a hall operating panel by use of which a user inputs a destination floor in a prescribed hall of an elevator. In a case an operation-prohibited floor of a car stopping at the hall is inputted as a destination floor from the hall operating panel, a group control device registers, as a service floor of the car, a floor preceding or beyond the destination floor inputted from the hall operating panel.

First claim

The invention claimed is:

1. An elevator group control system which is provided with two cars vertically connected to each other and performs a double operation in a prescribed running direction, comprising:
a hall operating panel which is provided in a prescribed hall of an elevator and by use of which a user inputs a destination floor; and
a group control device which, in the case where an operation-prohibited destination floor of one of said two cars stopping at the hall is inputted from the hall operating panel as a destination floor, determines whether
a call has already been registered for a floor preceding or beyond the operation-prohibited destination floor, and
when it is determined that a call has already been registered for a floor preceding or beyond the operation-prohibited destination floor, the group control device registers the floor for which the call has been registered as a service floor of the one of said two cars.

2. The elevator group control system according to claim 1 ,
wherein when it is determined that a call has not already been registered for either a floor preceding the destination floor or a floor beyond the destination floor, the group control device registers a floor higher than the destination floor as a service floor of the car.

3. An elevator group control system which is provided with two cars vertically connected to each other and performs a double operation in a prescribed running direction, comprising:
a hall operating panel which is provided in a prescribed hall of an elevator and by use of which a user inputs a destination floor; and
a group control device which, in the case where an operation-prohibited destination floor of one of said two cars stopping at the hall is inputted from the hall operating panel as a destination floor, determines whether
a call has already been registered for both a floor preceding the destination floor and a floor beyond the operation-prohibited destination floor, and
when it is determined that a call has already been registered for both a floor preceding the destination floor and a floor beyond the operation-prohibited destination floor, the group control device registers a floor higher than the destination floor as a service floor of the one of said two cars.

4. The elevator group control system according to claim 3 ,
wherein when it is determined that a call has not already been registered for either a floor preceding the destination floor or a floor beyond the destination floor, the group control device registers a floor higher than the destination floor as a service floor of the car.

5. An elevator group control system which is provided with two cars vertically connected to each other and performs a double operation in one running direction and performs a semi-double operation in the other running direction, comprising:
a hall operating panel which is provided in a prescribed hall of an elevator and by use of which a user inputs a destination floor;
a group control device which, in the case where an operation-prohibited floor of a car stopping at the hall is inputted from the hall operating panel as a destination floor, registers the destination floor inputted from the hall operating panel as a service floor of the car and registers a prescribed floor beyond the service floor as a transient floor; and
a car control device which, after the registration of the transient floor by the group control device, causes the car to move to the transient floor and thereafter causes the car to stop at the service floor.

6. The elevator group control system according to claim 5 , wherein in the case where an operation-prohibited floor of a car stopping at the hall is inputted from the hall operating panel as a destination floor, if a call has already been registered for any of floors beyond the destination floor, the group control device registers, as a transient floor, a floor most remote from the destination floor among floors for which a call has been registered.

7. The elevator group control system according to claim 5 , wherein in the case where an operation-prohibited floor of a car stopping at the hall is inputted from the hall operating panel as a destination floor, if no call has been registered for any of floors beyond the destination floor, the group control device registers a floor beyond the destination floor as a transient floor so long as a direction from a boarding floor to the destination floor coincides with a prescribed direction to be crowded.

8. The elevator group control system according to claim 5 , wherein in the case where an operation-prohibited floor of a car stopping at the hall is inputted from the hall operating panel as a destination floor, if no call has been registered for any of floors beyond the destination floor, the group control device registers, as a transient floor, a floor nearest to a terminal floor beyond the destination floor among floors at which the car can operate unless a direction from a boarding floor to the destination floor coincides with a prescribed direction to be crowded.
