Abstract: Most urban rail transit signaling systems use communication-based train operation control systems (CBTC).In order to ensure the safety of train operation, the safe communication between the vehicle and the trackside must meet the safety and reliability index requirements.Therefore, this article starts from the perspective of safe vehicle-ground communication protocol design between the vehicle and the trackside, and adopts two technical methods: customized network packet sequence method and cyclic redundancy check code encryption to ensure the real-time performance of vehicle-ground information transmission.Authentication and data security integrity verification.At the same time, this method also takes into account the efficiency of vehicle-toground communication and avoids the time-consuming shortcomings of complex algorithms.
