Abstract
A transmitter and receiver device used together with a control device provided on ground, which performs detection of a train, performs transmission and reception of a train detecting signal, and collates data added to a received train detection signal with predetermined data. A transmitter, to be connected to a track circuit, transmits a train detecting signal, to the track circuit, and a receiver, to be connected to the track circuit, receives the train detecting signal from the track circuit. The transmitter adds a first unique code to the train detecting signal transmitted from the control device provided on the ground and transmits the same to the track circuit. The receiver adds a second unique code to the train detecting signal which was the first unique code added thereto and received from the track circuit and transmits the same to the control device provided on the ground.
