Abstract

Abstract An elevator system for controlling cars on the basis of their separation from a destination, particularly for assigning hall calls to individual cars on this basis. The presence of an abnormally long spacing between a car and a destination, such as a hall call to be assigned, is sensed and a signal generated to represent that spacing. Landing count can be employed for normal spacing and a characteristic signal is utilized for the long spacing as encountered with a blind hatch region. A fixed pulse count is developed for each of the relatively uniform spaced landings and a proportionally longer pulse count is employed for the long travel increment of a blind hatch traverse. The blind hatch service factor is represented by a predetermined number of pulses which are accumulated on a per car basis in a master counter with other pulse series representing various service factors. The total counts for the cars are then compared and the hall call is assigned to the car with the lowest count as being best suited to serve the call.
