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

摘要

An elevator arrangement (1) is proposed to comprise a car (3), an elevator control (7) having information on a current position of the car (3), a plurality of fixtures (15), at least one sound generator (33) being provided at one of the elevator car (3) and each of the fixtures (15), and at least one sound detector (35) being provided at the other one of the elevator car (3) and each of the fixtures (15). Therein, the elevator arrangement (1) is adapted to perform a fixture position learning procedure comprising: - travelling the car (3) to and, preferably, stopping the car at each of the floors (5); -at each of the floors (5), generating a sound signal (37) using the sound generator (33) provided at a respective one of the car (3) and an associated one of the fixtures (15) located at the floor (5) where the car (3) is currently stopped, detecting the sound signal (37) using the sound detector (35) provided at a respective other one of the car (3) and the associated one of the fixtures (15) located at the floor (5) where the car (3) is currently stopped, determining a position information for the associated fixture (15) located at the floor (5) where the car (3) is currently stopped by assigning an information on a current position of the elevator car (3) provided by the elevator control (7) to the associated fixture (15), and storing such position information for subsequent identification purposes. With such elevator arrangement (1), the identity/position of each of a plurality of fixtures (15) may be determined in an automatically performed fixture position learning procedure.
