| الوصف: | Objective The millisecond-level precision of NTP (network time protocol) in train communication networks has increasingly failed to meet the requirements of high traffic and deterministic transmission. Meanwhile, existing research is limited to applying the PTP (precision time protocol) to train communication scenarios, lacking research on time synchronization in time-sensitive networks within train communication networks. Therefore, it is necessary to conduct relevant analysis. Method Firstly, based on the current research status of time synchronization in train communication networks, the deviation and delay in train communication networks are analyzed according to time-sensitive network synchronization protocols. Secondly, redundancy mechanis for clock service source failures and jumps are proposed. Finally, the effectiveness of the redundancy mechanism is verified through simulation of the time synchronization process. Result & Conclusion Time-sensitive networks are well suited for time synchronization of clock service sources in train communication networks, and their redundancy mechanisms effectively mitigate synchronization errors caused by clock service source failures and jumps. |
