Title:
CAR POSITION DETECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/067385
Kind Code:
A1
Abstract:
The present invention relates to a car position detection device that comprises: an identification plate (10) that is provided on each floor within a hoistway (1), and that has a slit pattern comprising a plurality of slits (11); a sensor (20) that is provided on a car (2) side, and that has an N number of coils (21) which generate an output value corresponding to a portion of the slit pattern; and a signal processing unit (31) that extracts an N-bit code string by threshold processing the output value of the N coils (21). On the identification plate (10), the slit pattern is formed such that an M-sequence code is generated. When the car (2) ascends or descends, the sensor (20) generates an output value by opposing a portion of the slit pattern. The signal processing unit (31) extracts a portion of the M-sequence code as the N-bit code string and is capable of determining whether the car is in a door zone or a re-level zone.
