Abstract An elevator control system using an electric type floor selector is disclosed including a unit provided at at least one of the specific floors in the hoistway and for indicating the specific floor, units provided at the other floors than the specific floors and for indicating merely the floor, a detector provided at a car in which presence of both the units is detected and when the detector levels with the respective units the detector generates a signal corresponding to it, a floor indicator for indicating the floor at which the car actually stops by using the detected signal, and a stop permissible floor indicator for indicating the electrically calculated stop floor when the car stops. Comparison is made of the output of the floor indicator with the output of the stop permissible floor indicator. In the comparison, when these outputs are different, the car is moved to the specific floor. When the car stops at the specific floor, the floor indicator and the stop permissible floor indicator are set to the specific floor.
An elevator control system using an electric type floor selector comprises: a unit provided at at least one of the specific floors in the hoistway and indicating the specific floor; units provided at the other floors than said specific floors and for indicating merely the floor; a detecting means provided at a car in which presence of both units is detected and, when said detector levels with said respective units, said detector generates a signal corresponding to it; a floor indicator for indicating the floor at which the car actually stops by using the detected signal; and a stop permissible floor indicator for indicating the electrically calculated stop floor when the car stops, in which comparison is made of the output of said floor indicator with the output of said stop permissible floor indicator; when these outputs are different, the car is moved to the specific floor and, when the car stops at the specific floor, said floor indicator and said stop permissible floor indicator are set to said specific floor.

An elevator control system using an electric type floor selector comprises: a unit provided at at least one of the specific floors in the hoistway and indicating the specific floor; units provided at the other floors than said specific floors and for indicating merely the floor; a detecting means provided at a car in which presence of both units is detected and, when said detector levels with said respective units, said detector generates a signal corresponding to it; a floor indicator for indicating the floor at which the car actually stops by using the detected signal; and a stop permissible floor indicator for indicating the electrically calculated stop floor when the car stops, in which comparison is made of the output of said floor indicator with the output of said stop permissible floor indicator; when these outputs are different, the car is moved to the specific floor and, when the car stops at the specific floor, said floor indicator and said stop permissible floor indicator are set to said specific floor.
Claim 3
Dependent Claim
64 words
An elevator control system using an electric type floor selector according to claim 1, in which a plurality of specific floors are used; a calculation is made of the distances between the floor indicated by said stop permissible indicator or the floor indicated by said floor indicator and the specific floors; and the car is moved toward the specific floor with the shortest distance.
