Abstract

A personal authentication device provided in a destination call registration device adapted to obtain authentication information from a user. The device includes an access control device adapted to, when the personal authentication device obtains the authentication information, obtain verification information including a plurality of pieces of permitted floor information corresponding to the authentication information and position information of the destination call registration device; and a supervisory controller adapted to determine, based on the verification information, whether a destination floor inputted into the destination call registration device is a permitted floor, and, based on the registration, control an elevator car.

Claims

1. An elevator system comprising:

a personal authentication device provided in a destination call registration device to obtain authentication information from a user;

an access control device to, when the personal authentication device obtains the authentication information, obtain verification information comprised of a plurality of pieces of permitted floor information corresponding to the authentication information and position information of the destination call registration device; and

a communication device to select one of group controllers based on the position information of the verification information and transmit the verification information,

wherein the group controller determines, based on the verification information, whether a destination floor inputted into the destination call registration device is a permitted floor, and, in the case of the permitted floor, assigns one of multiple elevator cars,

wherein;

the communication device comprises floor transformation data associating floors managed by the access control device and floors managed by the group controller and transforms permitted floors of the verification information managed by the access control device into floors managed by the group controller and transmits transformed information to the group controller.
