Research and Application of Train Communication Network Based on Time-sensitive Networking

Abstract

Objective TCN (train communication networks) has complex topologies and requires high real-time transmission capabilities. Currently, train data transmission mainly relies on TRDP (train real-time data protocol) for carriage, while there are issues of network latency uncertainty. TSN is thus adopted to ensure bounded latency for data transmission, addressing the aforementioned issues faced by TCN. Method A method called TTAM (TRDP and TSN adaptive method) is proposed to achieve protocol conversion between TRDP and TSN, ensuring data transmission in the network. Result & Conclusion Through the establishment of a TSN testbed, the functionality and performance of TSN networks (IEEE 802.1 AS and IEEE 802.1 Qbv) are tested, validating the effectiveness of TTAM in TSN technology application.
