With the improvement of the intelligence level of rail transit train network system,a fusion architecture of terminal device TRDP and time sensitive network(TSN)based on real-time Linux is proposed to meet the increasing real-time and deterministic requirements of the train communication network end-to-end.To verify its rationality,a testing platform has been designed to test the TSN-TRDP fusion architecture.The results show that the end-to-end time synchronization error of the two network nodes can reach ns-level,with a delay of μs-level,meeting the real-time Linux TRDP and TSN fusion application requirements.
