DEVICE OF SELECTING OUTPUT USING TRIPLE MODULAR REDUNDANCY FOR TRAIN CONTROL SYSTEM

摘要

PURPOSE: A device of selecting output using a triple modular redundancy for a train control system is provided to allow a user to maintain the operation of the device even when one or two output selection units has a problem through comparing three output selection units one more time. CONSTITUTION: An outputting apparatus is composed of a first operation unit(110), a second operation unit(120), a third operation unit(130), a first output select part(310), a second output selecting unit(320), a third output select part(330), and a final selection part(340). The first operation unit, the second operation unit, the third operation unit performs same calculation. The first output selection part, the second output selection part, and the third out selection part select output method through a predetermined method.
