ELEVATOR ARRANGEMENT ADAPTED FOR SOUND-BASED DETERMINING OF POSITIONS OF FIXTURES AT VARIOUS FLOORS

摘要

An elevator arrangement includes a car, an elevator control having car position current information, a plurality of fixtures, at least one sound generator at one of the car and each of the fixtures, and at least one sound detector at the other of the car and each of the fixtures. A fixture position learning procedure includes: travelling the car to and, preferably, stopping at each of the floors; at each floor stop, generating a sound signal from the sound generator at the car or the fixture at the floor stop, detecting the sound signal using the sound detector, determining a position information for the fixture at the floor stop by assigning information on a current position of the car from the elevator control, and storing the position information for subsequent identification purposes, whereby the identity/position of each of the fixtures is determined in the automatically performed learning procedure.
