Abstract

According to one embodiment, a method of operating an elevator system having at least one lane is provided. The method comprising: detecting a failure in the elevator system; detecting a location of the failure within the elevator system; determining a traffic pattern of the elevator car in response to the location of the failure, the traffic pattern operable to direct the elevator car to avoid the location of the failure; and moving the elevator car in accordance with the traffic pattern selected.

First claim

What is claimed is:

1. A method of operating an elevator system having at least one lane, the method comprising:
detecting a failure in the elevator system;
detecting a location of the failure within the elevator system, wherein the failure prevents movement of any elevator car of the elevator system at the location of the failure;
determining a traffic pattern of an elevator car in response to the location of the failure, the traffic pattern operable to direct the elevator car to avoid the location of the failure; and
moving the elevator car in accordance with the traffic pattern selected, wherein a lane where the failure is located is still available for use by the elevator car excluding the location of the failure, wherein landings above the location of the failure are still accessible by the elevator car in the lane where the failure is located.

2. The method of claim 1 , further comprising:
directing the elevator car to use a second transfer station when the failure has occurred in a first transfer station.

3. The method of claim 1 , further comprising:
directing the elevator car to a second lane when the failure has occurred in a first lane.

4. The method of claim 1 , further comprising:
directing the elevator car in a first lane to reverse direction of travel when the failure has occurred in the direction of travel in the first lane.

5. The method of claim 1 , further comprising:
directing the elevator car to transfer from a first lane to a third lane, when the failure has occurred in a second lane.
