Title:
ELEVATOR CAR LOCATION DETECTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/118317
Kind Code:
A1
Abstract:
Provided is an elevator car location detector device, comprising: an identification plate (120) which is configured of a conductor with an equivalent plate thickness to a surface film depth of an eddy current, and a sufficiently thick conductor; and a sensor (130) which moves relative to the identification plate. The sensor further comprises: an excitation coil (131B) which emits an alternating magnetic field; a detector coil (131A) which detects the amplitude and phase of an eddy current magnetic field which arises from the identification plate; and signal processing units (133-137) which detect from an output signal of the detector coil whether the sensor is facing a door zone or a re-level zone.
