Abstract:
Elevator systems having an elevator machine connected to an elevator car within an elevator shaft, the elevator shaft including a plurality of landings, at least one first sensor assembly attached to the elevator car, at least one second sensor assembly arranged within the elevator shaft and configured to interact with the at least one first sensor assembly, and a computing system in communication with at least one of the at least one first sensor assemblies and the at least one second sensor assemblies such that the computing system receives at least one of signals or data from the at least one of the at least one first sensor assemblies and the at least one second sensor assemblies. The at least one first sensor assemblies and the at least one second sensor assemblies form a contactless position sensing system for determining a position of the elevator car within the elevator shaft.
