  • Patent number: 12263873
    Abstract: An implementation method for an independent multimode train control system based on a trackside platform is provided. According to the implementation method, a trackside train control system and an interlocking system are provided independently to meet requirements of hybrid operation of trains having different systems; and at the same time, during operation of a train in a moving block mode, once a trackside control system fails or an on-board system fails, the multimode train control system can ensure that the train is degraded automatically and operates according to a degraded mode.

  • Patent number: 12246763
    Abstract: A disclosure relates to a degradation management method for a versatile signal system, a device and a medium. The versatile signal system supports both the CTCS system for the national railway and the CBTC system for the urban railway; the method controls the safety of trains equipped with the CTCS system or the CBTC system on the same line, and effectively conducts degraded operation management; and the management method comprises switching between normal operation modes of the CTCS system and the CBTC system, switching between degraded operation modes, and switching between normal operation modes and degraded operation modes in a shared area. Compared with the prior art, the disclosure has the advantage that effective degradation operation mode management on trains running on a line under a CTCS+CBTC signal system is realized.
