  • Patent number: 8998149
    Abstract: A ground device 1 transmits train control information to an on-board device mounted on a train. The ground device 1 receives a train detection signal (TD signal) from a train with an ATC/TD on-board device mounted thereon through loop coils 21 to 2m, and receives a train position signal from a train with a CBTC on-board device mounted thereon through wayside radio sets 61 to 6n. Based on the input train detection signal and train position signal, the ground device 1 detects the position of each train traveling on a route R, generates control information on each train based on the detected position of each train, and converts the control information to an ATC signal and a CBTC signal. The ATC signal is transmitted to the loop coils 21 to 2m through information transmission units 4, and the CBTC signal is transmitted through the wayside radio sets 61 to 6n.
