DEVICE TO DETECT FLOOR POSITION Russian patent published in 2015 - IPC B66B1/34 

FIELD: measurement equipment.

SUBSTANCE: invention relates to a device to detect lift system floor position. The lift system floor position detection device comprising at least the first unit of sensors, which comprises the first Hall sensor and is designed to detect at least one criterion of floor position and containing at least one unit of assessment. Besides, the unit of floor position criterion assessment serves to generate a floor signal, where the unit of sensors comprises at least the second Hall sensor. The assessment unit comprises at least one electronic circuit, which is designed to compare amplitudes of analogue signals from at least two Hall sensors. If amplitudes of signals are identical, the unit of assessment changes at least the condition of one digital switching. The lift system comprises at least one lift cabin, comprising a device for floor position detection, at least one first unit of sensors is placed on the lift cabin. The method to determine floor position with the floor position detection device consists in the fact that for generation of a floor signal they assess criteria of floor position from at least two Hall sensors.

EFFECT: invention provides for increased reliability of lift operation.
