“…Under the normal circumstances, the highly secure ATP (automatic train protection) system provides security protection for the train. However, because of the high complexity of ATP system, equipment failure is inevitable [3]. In order to minimize the impact on the operation, the train depends on manual driving completely after the removal of ATP [4,5], which is lack of effective technical means of prevention, and is in risk.…”

“…There have been a variety of attempts for the train collision warning system which is independent from the ATP signal system. Germany proposed the concept of RCAS (Railway Collision Avoidance System) in 2006 and has done a successful demonstration and validation in 2010 [3,5]. RCAS is mainly based on GPS satellite positioning and Ad-hoc network communication technology to complete the warning.…”

Anti-collision warning system is very important for urban rail train in ATP failure situation. The ranging method based on SDS-TWR principle can give the good ranging precision and long distance. However, in the case of multi-train, especially near the train node, the anti-collision warning system cannot work normally when the signal collision channel is busy. Combining the RFID label information, collision avoidance mode can promote fairness as all stations have equal probability of gaining access to the media. The method of SDS-TWR is used to model the wireless location of urban rail trains under high-speed moving conditions, and the actual measurement results are presented. The method proposed in this paper can effectively realize the distance detection of collision warning and improve the usability of train crash warning equipment in complicated environment.
