Train-ground communication system with redundant channel and redundant channel

The invention provides a train-ground communication system with a redundant channel and the redundant channel. The communication channel comprises a first LTE-M base station, a second LTE-M base station, a first LTE-M radio station, a second LTE-M radio station, a first Ethernet and a second Ethernet. The first LTE-M base station, the first Ethernet and the first LTE-M form a first communication channel for communication between the radio station vehicle-mounted equipment and ground equipment; the second LTE-M base station, the second Ethernet and the second LTE-M radio station form a second communication channel for communication between the vehicle-mounted equipment and the ground equipment; the communication system comprises ground equipment, vehicle-mounted equipment and the two communication channels, and the ground equipment and the vehicle-mounted equipment are in data communication through the first communication channel and the second communication channel which are arranged in a redundant mode.
