Abstract：Research purposes: The train control centre system for CTCS is an important signal equipment for achieving the sixth speed-raising in China railways. Meanwhile，it is crucial equipment for completing the ground information processing and transmitting dynamic information to the train. This research is aimed at the interpenetration between the train control centre and other train control equipment } as well as the unification of their interface protocols on basis of CTCS2.
Research methods: By analysis of the relay interfaces among the existing signal systems，a series of guidable technical measures are put forward for the train control center interface on basis of the CTCS2 and the possibility is also analyzed of adopting the international standard safety digital interfaces.
Research results: The train control centre interfaces for CTCS2 adopting the international standard safety digital interface can overcome the inherent disadvantages of the existing relay interfaces. This will have the important significance in developing and applying the domestic high speed railway equipment with plug and play function.
Research Conclusions: The train control centre digital interfaces for CTCS2 is safe and reliable. It is feasible to achieve the interconnection between equipment with plug-and-play function.
