Elevator system which limits the number of destination call registrations to be allocated to the single car
In an elevator system, a group supervisory control apparatus selects a car responding to a destination call registration performed on a landing destination operating panel. A limit value of the number of destination call registrations for stop floors existing in the same direction from the same stop floor is set in the group supervisory control apparatus in a manner corresponding to the stop floor. The group supervisory control apparatus counts the number of destination call registrations for the stop floors existing in the same direction from the same stop floor in response to the destination call registration performed on the landing destination operating panel, and limits the number of destination call registrations to be allocated to the single car according to a limit value corresponding to the stop floor.
1. An elevator system comprising:
a plurality of cars;
a plurality of landing destination operating panels provided to landings on a plurality of stop floors, each of the landing destination operating panels being for enabling a destination call registration; and
a group supervisory control apparatus for selecting the car responding to the destination call registration performed on the landing destination operating panel,
wherein a limit value of the number of destination call registrations for the stop floors existing in the same direction from the same stop floor is set in the group supervisory control apparatus for each of the stop floors, and
the group supervisory control apparatus counts the number of destination call registrations for the stop floors existing in the same direction from the same stop floor in response to a destination call registration performed on the landing destination operating panel of the same stop floor, and limits the number of destination call registrations to be allocated to a single car according to the limit value corresponding to the stop floor.
2. The elevator system according to claim 1 , wherein the stop floors, on which the landing destination operating panels are provided, are registered in the group supervisory control apparatus in such a manner that the stop floors are classified into a general floor and a crowded floor expected to be more crowded than the general floor, and the limit value for the crowded floor is set smaller than that for the general floor.
3. An elevator system comprising:
a plurality of cars;
a plurality of landing destination operating panels provided to landings on a plurality of stop floors, each of the landing destination operating panels being for enabling a destination call registration; and
a group supervisory control apparatus for selecting the car responding to the destination call registration performed on the landing destination operating panel, wherein the group supervisory control apparatus comprises:
means for setting a limit value, for each of the stop floors, of the number of destination call registrations for the stop floors existing in the same direction from the same stop floor, wherein the means for setting a limit value comprises means for counting the number of destination call registrations for the stop floors existing in the same direction from the same stop floor in response to a destination call registration performed on the landing destination operating panel of the same stop floor, and
means for limiting the number of destination call registrations to be allocated to a single car according to the limit value corresponding to the stop floor.
4. The elevator system according to claim 1 , wherein the group supervisory control apparatus further comprises means for classifying the stop floors into a general floor and a crowded floor expected to be more crowded than the general floor, wherein the limit value for the crowded floor is set smaller than that for the general floor.
