Position measurement signal processing unit in which redundant receiver units are provided for each position measurement station to enable redundancy checking of received measurements by processor units

摘要

The processing unit processes the position measurement data from a number of measurement stations (1,2). Each measurement station is connected to a receiver assembly (4,5) that has two receiver units (4.1,4.2,5.1,5.2). The redundant measurement signals from the receiver units for each receiver assembly are compared in a comparator unit (6,7). An Independent claim is made for a method for the safe processing of position measurement signals.
