Claims

[Scope of utility model registration request]

(1) A level crossing controller that detects the approach of a train by configuring a closed loop circuit with a transmitter, a rail, an axle of the train, and a receiver, which is attached to the rail and continuously operates when the train is running. a microphone that collects vibration sounds peculiar to trains transmitted through the rails;
and a train vibration sound detector connected to the microphone and detecting the approach of the train from the vibration sound signal.

(2) The level crossing controller according to claim 1, in which the receiver takes an OR between train approach detection using a closed-loop circuit configuration and train approach detection using a train vibration and sound detector.
