ABSTRACT:
Elevator cars for servicing a plurality of floors are under the control of register means provided at elevator halls to registrate the hall calls for the up- and down-directions. Detector means are installed at the elevator halls to detect the number of the passengers awaiting the cars at the halls. Discriminator means are employed to obtain the information concerning the number of the car awaiting passengers classified for each of the directions of their destinations. The information thus obtained is utilized in the elevator control apparatus to operate the elevator system with a high working efficiency. When the hall calls for one direction are registrated, the detected number of the car awaiting passengers is regarded as the number of the awaiting passengers for the hall calls of the above one direction. When the hall calls for the two directions are registrated, the detected number of the car awaiting passengers are divided into two classes, one for one direction and the other class for other direction on the basis of an appropriate dividing ratio, to thereby detect the number of the awaiting passengers for each of the directions of their destinations. This information about the number of the passengers for each of the directions is utilized in the elevator control operation for allotting the registrated hall calls to the cars. Adder devices are provided for adding together the number of the car awaiting passengers relevant to the allotted hall calls and the number of the passengers in the car to estimate the number of the passengers to be transported by the car. The information of the estimated number of the passenger is utilized for predicting the possible occurrence of the car-full condition. The allotment of the hall calls to the car for which the no-vacancy condition is predicted is restricted.
