Abstract:
1. A train signaling system comprising: a traffic signaling chain terminus set up unit configured to set a terminus location of a train running on the track and transmit a wireless traffic signal; a plurality of traffic signaling chain relay units installed along the track and configured to forward the wireless traffic signal and allow the wireless traffic signal to form a traffic signaling chain comprising distance-to-go information of the train; and a traffic signaling chain detection unit configured to allow the train to achieve the receipt of the information on the traffic signaling chain and calculate the distance-to-go of the train; wherein each traffic signaling chain relay unit has a plurality of levels; and each traffic signaling chain relay unit comprises: an ID set up unit configured to set a present level relay unit ID information and an upper level relay unit ID information; a relay spacing set up unit configured to set a spacing information between the present level relay unit and the upper or next level relay unit; and a signaling chain length accumulation unit configured to accumulate the spacing of each relay unit level by level.
