PURPOSE: To provide a speed collation apparatus which uses limited fail-safe speed comparison slots and which performs a speed collation having more speed comparison functions than the number of slots by a method wherein a speed band is formed by combining a first speed pattern with a second speed pattern or the like and the speed band is used for the speed collation with a train speed. CONSTITUTION: A train speed V1 , for speed collation, which is detected from an axle performing a collation, a train speed V2 , for check, which is detected from an axle other than the axle, a speed limit V5 by an ATC signal or the like, a first speed pattern V3 at a speed which is by a definite valueα1 higher than a low position side out of the V5 , the V1 and the V2 , a disconnection- detection judgment speed V6 which is given to a speed detection circuit in advance and a second speed pattern V4 at a speed which is by a definite valueα2 lower than a high position side out of the V6 , the V1 and the V2 are combined to form a speed band. A speed collation is performed by using the speed band, a collation output is output as a brake output, a limited fail-safe speed comparison slot is used, and the speed collation having more comparison functions can be performed. |
