The embodiment of the invention provides a train-ground communication method and system for a coupled train. The method comprises the following steps that: a VOBC at the head end of a first train is activated; a head-to-tail through line of the first train is connected with a head-to-tail through line of a second train through vehicle automatic couplers; the first VOBC is connected to a first train-ground wireless network through a TAU at the head end of the first train and the first VOBC is connected with the TAU at the tail end of the first train through the first head-to-tail through line to access a second train-ground wireless network. Therefore, the coupled train only needs to perform train-ground communication through the first VOBC, signal interference caused by simultaneous train-ground communication of the two VOBCs is avoided, and the driving safety of the train is ensured.
本发明实施例提供一种连挂列车的车地通信方法及系统,所述方法包括:通过激活第一列车首端的VOBC,并将第一列车的首尾贯通线与第二列车的首尾贯通线通过车辆自动车钩连接,第一VOBC通过第一列车首端的TAU连接接入第一车地无线网络,并通过第一首尾贯通线与第一列车尾端的TAU连接接入第二车地无线网络,从而连挂列车只需通过第一VOBC进行车地通信,避免两个VOBC同时进行车地通信带来的信号干扰,保证了列车的行车安全。
