Train resident in belt detection manner and its device null carriage rail

摘要

PROBLEM TO BE SOLVED: To reliably detect a train existing railroad line without being affected by an increase in train short circuit resistance caused due to rust on a rail, and to prevent erroneous detection based on reduction of a reception level at rainfall.;SOLUTION: In a zone where much rust is caused on the rail, based on a train detection signal from a track circuit behind in a train moving direction out of adjacent track circuits, a train detection determination level of the track circuit is increased.;COPYRIGHT: (C)2007,JPO&INPIT
