  • Onboard system, ground system, and information transmission system
    Patent number: 11180169
    Abstract: An information transmission system includes a ground system provided to a track and an onboard system installed in a train. The ground system includes two (M=2) track antennae selected from N types of track antennae with different resonance frequencies. The two track antennae are arranged side by side in a left and right direction relative to a traveling direction of the train. When the train passes through a position where the ground system is provided, the onboard system detects the two track antennae at once and can determine the resonance frequencies of the track antennae.
