Abstract: The present disclosure relates to a train autonomous control system (TACS) based method for train interval protection control, and an apparatus for the method. The method includes: step one: receiving, by a carborne controller (CC), a train operation command sent by an automatic train supervision (ATS) system to obtain a movement mission; step two: calculating, by the CC, a train guaranteed zone in real time according to information of train localization, car characteristics, and carborne controller characteristics; step three: calculating, by the CC, track resources required to be used in combination with current mission information according to the train guaranteed zone, and requesting to a wayside information control (WSIC) for information of collided trains occupying these track resources; and step four: sending, by the WSIC, a list of the collided trains on the track resources required to be used to the CC according to information of the track resources required to be occupied by a train on a whole line.

Abstract: The present disclosure relates to a global train-localization system. The system may autonomously send a precise location of a train to effectively cope with train location recognition in a case of various faults or degradations. The localization system includes: a backup localization unit installed on the train and configured to read beacon location information on a track; and a global train-localization system (GTS) server configured to receive, store and convert train localization information sent by the backup localization unit and to perform output and display. Compared to the prior art, the present disclosure has the advantages of effectively coping with system degradation, namely, tracking the location of the train in real time even in a case of complete fault of a signal system, etc.

Abstract: The present disclosure relates to a stent delivery component, a stent delivery system and a stent system. In particular, a stent delivery component including a base and at least two clamping wings which are rotatably connected with the base, respectively, is provided.
