Abstract


In order to ensure the safe operation of trains , improve the efficiency of rail transport , the urgent need for state-of-the-art equipment performance , safe and reliable train operation control system . Reference to the European Train Control System ( ETCS ) , China 's railway sector development suited to China 's national conditions of China Train Control System ( Chinese Train Control System CTCS ) . China is building 300 km / h or more passenger dedicated line and the Beijing - Shanghai high-speed railway widely used GSM-R wireless communications - based high-reliability , high security CTCS - 3 column control system . CTCS - 3 train control system , RBC switching is one of the key features of the vehicle equipment , a serious impact on the operational efficiency of the train . In this paper, a hierarchical modeling idea for modeling and analysis of on -board equipment RBC switching function . First create a GSM-R application layer model , the model can simulate the obtained data transmission process in the air , the result message is lost due to the failure of the channel and time delay ; followed on the basis of the GSM-R application layer model , create a cycle messaging model and non-periodic message model , aperiodic message model can simulate the vehicle equipment with RBC messages between interaction and message retransmission mechanism ; once again based on the non-periodic message model , to establish communication between the vehicle equipment with RBC meeting model and terminate the communication meeting model , and then get the switch model and switch model based on two car radio RBC RBC based on a car radio . Finally, the CPN model simulation experiments , a comparative analysis of the two RBC switching mode , the speed of the train running at the same time , the message retransmission interval and RBC overlapping ranges of RBC switching the factors affecting the success rate of in-depth analysis for CTCS - 3 train control system research and implementation of the project to provide a reference .
