The invention relates to an inter-train direct communication method and an inter-train direct communication device, and belongs to the technical field of rail transit, the inter-train direct communication method comprises the following steps: obtaining an ID of a current train and a train ID of a receiving terminal of the current train; the position information of the current train is sent to a receiving terminal through a Beidou satellite navigation system; receiving position information sent by other trains to the current train; according to the received position information of the other trains and the position information of the current train, the position of a communication train of the current train and the ID of the communication train are judged; the current train sends information to the communication train and receives the information sent by the communication train, and communication between the current train and the communication train is carried out. According to the inter-train direct communication method, the position sharing between the trains can be realized, the communication train of the current train is judged according to the train position, and the ID of the communication train is obtained, so that the current train can directly communicate with the communication train, the communication time delay can be shortened, the Doppler frequency shift is reduced, and the communication efficiency is improved. And trackside equipment and communication nodes can be reduced, and the running safety of the current train is ensured.
本发明涉及一种列车间直接通信方法及列车间直接通信装置,属于轨道交通技术领域,列车间直接通信方法,包括以下步骤:获取当前列车的ID以及当前列车的接收终端的列车ID;将当前列车的位置信息通过北斗卫星导航系统发送给接收终端;接收其他列车向当前列车发送的位置信息;根据接收的其他列车的位置信息以及当前列车的位置信息,判断当前列车的通信列车的位置以及通信列车的ID;当前列车向通信列车发送信息以及接收通信列车发送的信息,进行当前列车与通信列车之间的通信。上述列车间直接通信方法中可实现列车间位置的共享,根据列车位置,判断当前列车的通信列车,并获取通信列车的ID,以使当前列车可与通信列车直接进行通信,不仅可以以缩短通信时延、减少多普勒频移,还可以减少轨旁设备和通信节点、保证当前列车运行的安全性。
