Abstract
PURPOSE: To form a circuit in a fail safe, by forming in parallel a check circuit and by nullifying a brake instruction of the check circuit which is defetive due to magnetic erasing of each relay.
CONSTITUTION: Signals of a receiver RD on a train, which receives a limit signal of a train speed transmitted from a ground, and of a speed generator TG, which generates a signal being in proportion to a speed of an electric train, are input to check circuits CHD1 and CHD2 of No.1 and No.2 respectively. When a TG signal is found to be larger as a result of comparision of signals from the RD with signals from the TG, both check relays CHR1 and CHR2 are magnetic-erased and a check signal is output. The check signals CHS1 and CHS2 magnetic-erase check relays CMR1 and CMR2 via check circuits CHD1 and CHD2 respectively in the case of no pressure. Magnetic erasion of the check relay can nullify a brake instruction of a check circuit which is defective, and a circuit can be formed in a fail safe.
