Research on fusion technology of terminal device TRDP and TSN based on real-time Linux in train communication network
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.
