Floor position detection device of the lift installation and method for generating floor signals

摘要

The invention relates to a floor position detection device 26 of a lift installation and a method for generating a floor signal. The floor position detection device 26 includes an evaluation unit 36 and a sensor unit 35 for generating a floor signal comprising two states. The floor signal may adopt two states: "in range of floor" or "out of range of floor". The sensor unit 35 comprises a first Hall effect sensor 28 for generating a first floor position feature value and a second Hall effect sensor 30 for generating a second floor position feature value. Evaluation unit 36 is designed to generate a floor signal based on the comparison between the first and second floor position feature values. According to the invention, the evaluation unit 36 is provided for verifying whether the first and / or second floor position feature value is greater than the first threshold value and generating a floor signal based on the result of the verification.
