Abstract (en)
[origin: WO03011733A1] The invention relates to a lift system comprising an absolute length measuring system for determining the position of a cage which can be displaced along at least one guiding rail, said guiding rail comprising an absolute code mark pattern of a pseudo-random codification arranged in the direction of displacement. One such measuring system enables an increased resolution to be easily achieved in the detection of position over a long displacement path of the lift cage. To this end, the absolute code mark pattern and the incremental code symbol pattern are represented as a single-track combined code mark pattern of the n-position pseudo-random sequence in Manchester encoding, with code marks having the same length, and the code reading device comprises reading stations for scanning successive n+1 code marks, the second code mark of the single-track combined code mark pattern being respectively scanned.
