ELEVATOR STOPPING POSITION-DETECTING DEVICE

WIPO Patent Application WO/2013/035368

A1

The elevator stopping position-detecting device is provided with floor arrival reference plates (6) that are disposed on the wall of a building and a position-detecting unit (5) disposed on the elevator car (1). The floor arrival reference plates (6) are provided with a detected resonance circuit comprising a detected coil (11). The position-detecting unit (5) is provided with: detecting coils (13, 14) that are set parallel along the movement direction of the car (1) and connect electromagnetically to the detected coil (11); detecting circuits (18, 19) that output the direction of displacement and magnitude of displacement of the car (1) based on the output of the detecting coils (13, 14); a differential circuit (20); an adder circuit (21); a variable gain amplifier circuit (22); etc. As a result of said configuration, the stopping position of the elevator car can be detected safely and with high precision.
