System and method for controlling a plurality of elevator cabs in an elevator shaft

摘要

A system and method for controlling a plurality of elevator cabs in an elevator shaft of a structure, the system and method comprising: at least one elevator shaft having a plurality of zones, each zone representing at least one layer of the structure; At least one zone having at least one sensor; At least two elevator caps each of which is movable in the shaft independently of the other; And a controller for determining the movement of each cap in the area. The first cap preceding any other cap is designated as a leading cap; Each cap following the preceding cap designated as a trailing cap; Each cap being movable along the same travel direction to a service area until each cap reaches its designated end zone; The controller instructs the trailing cap to the sensor to move to the zone only after the sensor in the zone has detected that the cap in which it was placed has left the zone.
