ABSTRACT:
In an elevator control system, in which the elevator car is controlled on the basis of elevator car positions obtained through the counting of distance pulses provided in proportion to the distance travelled by the car and floor height data indicative of the heights of individual floors, the distance pulses are counted by moving the car at a low speed from the lowest floor to the highest floor, and the count at the time of the actuation of a floor position detector, which is actuated when the car passes by each floor, is stored as the floor height value of that floor in a RAM (Random Access Memory). With this arrangement, the measurement of the floor heights is facilitated, and also the preparation of a ROM (Read-Only Memory) for storing the floor height data for each elevator car is made needless to promote the standardization.
