Abstract
An elevator system (20) includes an elongated member (30, 32, 34) that may sway under certain conditions. An exemplary method of controlling the elevator system (20) includes selectively controlling an elevator car dispatching schedule when a condition exists that is conducive to sway of one of the elongated members (30, 32, 34). The control over the elevator car dispatching schedule controls the time that the elevator car is in a predetermined critical zone while the condition exists such that the time does not exceed a selected amount.
Claims20
A method of controlling an elevator system, comprising
- selectively controlling an elevator car dispatching schedule when a condition exists that is conducive to sway of an elongated vertical member associated with the elevator car to control a time that the elevator car is in a predetermined critical zone while the condition exists such that the time does not exceed a selected amount.
An elevator system, comprising:
- an elevator car;
- an elongated vertical member associated with the elevator car;
- a detector for detecting a condition conducive to sway of the elongated vertical member;
- and
- a dispatching schedule controller that controls a dispatching schedule for the elevator car when the condition exists such that an amount of time the elevator car is in a predetermined critical zone does not exceed a selected amount.
