12344291 · 2025-07-01 · ·

A system and method for monitoring failure of a train within a tunnel is disclosed. The method comprises receiving, by the central server, an estimated crossing time for the train to cross the tunnel and the latest location of the train from a telemetry system onboard the train. The telemetry system comprises a Head-of-Train device communicatively coupled to an End-of-Train device. The method further comprises detecting a failure event associated with the train, by the central server, if an attempt to establish communication with the telemetry system is unsuccessful after the estimated crossing time. The method further comprises broadcasting, by the central server, an emergency alert message indicating the failure event to one or more receiving devices based on the latest location of the train. The receiving device is associated with at least one of an operator control station and an adjacent train.

Permanent-magnet magnetic levitation rail transit control system based on 5G communication technology

Disclosed in the present invention are a permanent-magnet magnetic levitation rail transit control system and method based on 5G communication technology. The system comprises: an intelligent control center, a 5G communication platform, a train security system, an Internet of things monitoring system, and a passenger service system. In the present invention, targeted at the problem of being difficult to ensure barrier-free transmission of signals even by means of beamforming technology due to high moving speed of a permanent-magnet magnetic levitation rail transit system and small coverage of 5G base stations, a multi-connectivity scheme is used, and the intelligent control center selects two 5G base stations for signal transmission at the same time depending on distribution of 5G base stations along a line, wherein one 5G base station is the current closest base station, and the other 5G base station is the next base station to be approached. By means of a relay-type base station passing mode, it is ensured that a 5G communication platform can provide a stable and reliable communication link.

METHOD, RAILROAD CAR AND COMPUTER PROGRAM PRODUCT FOR OPERATING A RAILROAD CAR GROUP
20250242847 · 2025-07-31 ·

A method operates a railroad car group, which is delimited by a front car and a rear car. In at least one of the two mentioned cars, a status indication is determined that indicates the position and/or the speed of this car. The status indication is transmitted to a track-side communication facility. The track-side communication facility relays the status indication to the other of the two mentioned cars, and in each case in the other of the two mentioned cars, the received status indication and another status indication that indicates the position and/or the speed of this other car are subjected to a plausibility check. A safety measure is triggered in the other car if the plausibility check indicates a separation of the railroad car group.
