To address the technical challenges associated with the application interoperability of RBC handover process between the new-type train control system and the CTCS-3 level train control system,an in-depth research has been conducted on the differences of RBC handover process between the two train control systems.According to the RBC handover process for CTCS-3 level train control system and the characteristics of the new-type train control system,the key technical requirements for RBC handover between the two train control systems are distinguished from the aspects of the calculation method of movement authority,interactive information,and train-ground communication protocols.The differences of RBC handover between the two train control systems are analyzed from the key links such as the processing strategies of train information,train protection,communication fault handling,the checking of first section after the boundary,and the management of train under backup supervision mode.This work serves as a valuable foundation for problem analysis and engineering design related to RBC handover scenarios in practical applications,and provides theoretical foundations and technical supports for railway line upgrades and cross-system interoperation in future.
