CODING DEVICE, POSITION-DETERMINING DEVICE, AND POSITION-DETERMINING METHOD

摘要

The invention relates to a computer-implemented method for determining the position of an elevator cab in an elevator shaft by means of a coding device, which coding device comprises a code strip (2) as a marking, in order to increase safety. The position is determined analytically by means of an algorithm on the basis of the code (4) of the marking, wherein an extrapolated position is determined from stored positions and the time of the recording and in turn a coding pattern to be compared is calculated with respect to the recording by reversing the algorithm.
