SIGNAL SELECTION SYSTEM IN REDUNDANT LINE

摘要

PROBLEM TO BE SOLVED: To prevent generation of non-matching signals between the transmission line signals of redundant constitution. SOLUTION: This system is provided with an input IF part for inputting first and second signals C1 and C2 from the respective input lines of the redundant constitution, a first output IF part for selecting a normal signal by itself and outputting it to a first redundant output line for the branching signals C1a and C2a of the first and second input signals, a second output IF part for selecting the normal signal by itself and outputting it to a second redundant output line for the other branching signals C1b and C2b of the first and second input signals and a signal selection control part for detecting the non-matching signal selection in the first and second output IF parts and matching the selection of the respective branching signals in the first and second output IF parts to a signal input system (C1 or C2) without abnormality for the respective branching signals.
