Elevator position detection systems

An elevator system comprising:

• an elevator machine operably connected to an elevator car located within an elevator shaft, the elevator shaft including a plurality of landings;
• at least one first sensor assembly attached to the elevator car comprising a first sensor, a second sensor, and a third sensor;
• a plurality of second sensor assemblies arranged within the elevator shaft and configured to interact with the at least one first sensor assembly, wherein each landing of the plurality of landings includes an associated second sensor assembly from the plurality of second sensor assemblies;
• and
• a computing system operably connected to and in communication with at least one of (i) the at least one first sensor assembly and (ii) the plurality of second sensor assemblies such that the computing system receives at least one of signals or data from the operably connected assembly or assemblies when the at least one first sensor assembly interacts with a second sensor assembly of the plurality of second sensor assemblies,
• wherein the at least one first sensor assembly and the plurality of second sensor assemblies form a contactless position sensing system for determining a position of the elevator car within the elevator shaft,
• wherein each of the plurality of second sensor assemblies comprises a plurality of tags, wherein a first tag is arranged to align with the first sensor, a second tag is arranged to align with the second sensor, and a third tag is arranged to align with the third sensor and the third tag comprises a first tag element and a second tag element separated by a tag spacing distance and a third tag element, the third tag element having a predetermined frequency selected to enable identification of a respective associated landing of the plurality of landings by the contactless position sensing system, wherein the predetermined frequency of the third tag comprises encoded information to uniquely identify each landing, and
• wherein the computing system is configured to:
• determine a landing error for each landing to compensate for installation errors to determine a set landing position for each landing based on an interaction of the first, second, and third sensors with the respective first, second, and third tags at each landing;
• identify, during elevator operation, a specific landing based on a detected third tag of a second sensor assembly, and
• control the elevator machine to adjust, during the elevator operation, a landing position of the elevator car to the set landing position at the specific landing based on an interaction of the first, second, and third sensors with the respective first, second, and third tags at each landing.
