The invention discloses a rail traffic train-to-train communication method based on space-time division multiple access. The method comprises the steps of firstly, determining the position and speed information of each train through a transponder, a speed sensor and wireless positioning equipment, dividing a same-frequency channel of train communication into a plurality of time slots in a time division multiplexing mode, combining the relationship between the position of each train and a kilometer post, numbering trains, each train occupying one time slot, and after all the trains occupy the time slots, enabling all the time slots to circularly occur in time, so that in a certain distance range, same-frequency interference between the trains is avoided, and direct communication between the trains can be realized. By multiplexing and combining the time slots, the utilization rate of the time slots is increased, and frequency resources can be greatly saved. Meanwhile, the method can be combined with a current CBTC system, and a more favorable guarantee is provided for safe operation of the trains under the condition that the system breaks down or manual operation errors occur.

    本发明公开了一种基于空时分多址的轨道交通车车通信方法,该方法首先通过应答器、速度传感器以及无线定位设备,确定列车的位置、速度信息,通过时分复用的方式,将列车通信的同频信道分为若干时隙,结合列车的位置与公里标的关系,给列车编号,每辆列车占用其中一个时隙,当所有列车占用时隙结束之后,各个时隙在时间上循环地发生,从而在一定的距离范围之内,既避免列车与列车之间的同频干扰,又可以实现列车与列车之间的直接通信。通过对时隙的复用与组合,不仅增加时隙的利用率,还可大大节省频率资源。同时该方法可结合当前的CBTC系统,在系统出故障或人为操作错误的情况下,为列车的安全运行提供一种更有利的保障。
