Abstract
A floor position detection device of an elevator installation, and a method for generating a floor signal, includes a sensor unit and an evaluation unit for generating the floor signal with two states. The states are “in the range of the floor” and “outside the range of the floor”. The sensor unit includes a first Hall effect sensor generating a first floor position characteristic value and a second Hall effect sensor generating a second floor position characteristic value. The evaluation unit generates the floor signal on the basis of a comparison between the first and the second floor position characteristic values. The evaluation unit verifies whether the first and/or second floor position characteristic value is higher than a first threshold value and generates the floor signal on the basis of the result of the verification.
